J Clin Med 2024; 13:3287. [PMID: 38892997 PMCID: PMC11172714 DOI: 10.3390/jcm13113287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/23/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
Background: The Carlevale lens (FIL SSF, Soleko IOL Division, Italy) is a new lens for suture-less scleral fixation. This paper aimed to systematically review articles on this lens, the surgical techniques used for its implantation, complications and outcomes. Methods: This systematic review was performed following the PRISMA guidelines. The search string used was "Carlevale" AND "scleral fixation" from inception until March 2024. For completeness, either case-control studies, case reports or case series written in English were included. The authors used the Newcastle-Ottawa scale for the case-control studies and the JBI Critical Appraisal Checklist for case reports and case series. Results: Twenty-nine articles were included. Scleral fixation with Carlevale lens can be performed by creating scleral flaps or, alternatively, by using scleral pockets. The two sclerotomies must be diametrically opposed, and are preferably created by 25-gauge trocars. A pars plana vitrectomy should be performed every time, and the design of the lens should be suitable for self-anchoring to the sclera; the most accredited strategy to achieve this is to avoid scleral sutures. There were only a few intraoperative and postoperative complications reported; vitreous hemorrhages were the most frequent intraoperative events, while the most relevant postoperative complications were vitreous hemorrhages, cystoid macular oedema and transient variations in the intraocular pressure. Excellent results have been obtained in terms of BCVA, IOL centration and stability, mean intraocular pressure, postoperative spherical equivalent, separation between anterior and posterior chamber and the distance of the IOL from anterior chamber structures. Conclusions: The foldable hydrophilic design of the Carlevale lens has shown good effectiveness, IOL stability and few intra and post-operative complications.

J Cataract Refract Surg 2024; 50:605-610. [PMID: 38350232 PMCID: PMC11146187 DOI: 10.1097/j.jcrs.0000000000001421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/15/2024]
Abstract
PURPOSE To evaluate which secondary intraocular lens (IOL) implantation technique was more successful in achieving the best postoperative results and refractive outcomes between retropupillary iris-claw IOL (ICIOL) and flanged intrascleral IOL (FIIOL) fixation with the Yamane technique. SETTING Eye Clinic of the University of Trieste, Trieste, Italy. DESIGN Retrospective observational study. METHODS 116 eyes of 110 patients who underwent ICIOL or FIIOL were analyzed. Patients with follow-up shorter than 6 months or with incomplete clinical data were excluded. Collected data included demographics, ocular comorbidity, indication of surgery, intraocular pressure, early (≤1 month) and late (>1 month) postoperative complications, corrected distance visual acuity (CDVA), and manifest refraction at the last follow-up visit. RESULTS 50% (n = 58) of eyes underwent FIIOL and 50% (n = 58) ICIOL implantation for aphakia (n = 44, 38%) and IOL dislocation (n = 72, 62%). No statistically significant differences in demographics, comorbidity, follow-up duration, postoperative complications, and surgical indications were found. The refractive prediction error (RPE) was 0.69 ± 0.94 diopter (D) in the FIIOL group and 0.21 ± 0.75 D in the ICIOL group ( P = .03), indicating residual hyperopia after both techniques. RPE, mean absolute error, and median absolute error were higher in the FIIOL group ( P = .003). ICIOL implantation was more successful in obtaining a RPE between -0.50 D and +0.50 D (52% of ICIOL, n = 30, and 31% of FIIOL, n = 18). CONCLUSIONS Both techniques were effective in increasing preoperative CDVA with no statistical difference between them. Although complication rates did not significantly differ, the FIIOL group exhibited less predictable refractive outcomes. Adjusting the dioptric power of the 3-piece IOL, as performed in ciliary sulcus implantation, to prevent myopic shift, is not recommended.

Abstract
INTRODUCTION Single-haptic iris-claw intraocular lens (IOL) dislocation is not an uncommon complication. A few different surgical techniques are available for its refixation but usually involve a more invasive approach. We aim to demonstrate an original and simple approach for refixation of single haptic retropupillary iris-claw IOL subluxations. METHODS We present a case of an 80-year-old male with a single haptic retropupillary iris-claw IOL subluxation in a previously vitrectomized eye. We used a new surgical approach to refix this type of subluxation. RESULTS This new technique uses only two 30-gauge needles (one of them connected to a viscosurgical device) to re-enclavate the subluxated haptic of the retropupillary iris-claw IOL. By minimising surgical manipulation, the patient's postoperative period was uneventful. CONCLUSIONS We highlight a new, quick, safe, and unusual surgical approach to single-haptic retropupillary iris-claw IOL dislocation in vitrectomized eyes. Because of its characteristics, we named it the "fencing" IOL repositioning technique.

Abstract
This study aimed to describe a novel modified surgical technique for FIL SSF lens (Rome, Italy: Soleko) implantation. A retrospective study of FIL SSF lens implantation on six eyes of six patients with subluxated or dislocated intraocular lens (IOL). Standard pars plana vitrectomy (PPV) was performed in all patients. The subluxated or dislocated IOL was removed from a 2.4 corneal incision. From the same incision, the folded FIL SSF lens was inserted. Then lens plugs were extremized through a 23G scleral incision inside two 4 mm pockets that were created at the beginning of the operation. In two cases one pocket had to be converted into a triagonal-shaped scleral flap. All scleral pockets were sutured with 7.0 Vicryl suture and the conjunctiva with 7.0 Vicryl. In the follow-up period of six months, the lens is centered and not tilted. The refractive outcome is within the expectations. Visual acuity is improved in all patients. No haptic exposure and no other complications were noted in all cases. FIL SSF lens is a good option for treating aphakia. This modified implantation technique is safe, fast, and easy. It is also versatile, combining the advantages of both previously described techniques, as it gives the option of flap conversion if needed. Larger studies and prospective comparative studies can highlight the best and more appropriate technique.

Abstract
PURPOSE We evaluated the pupillary characteristics and response to light and drugs in eyes with posterior chamber (PC) placement of iris-claw intraocular lens (IC-IOL). METHODS In this cross-sectional, comparative study, we included adults with an IC-IOL implanted in the PC of a single eye. We excluded patients with ocular trauma, postoperative IC-IOL displacement or complications, and extended iris atrophy. We used anterior segment optical coherence tomography to perform light-controlled pupillography, measure the pupil diameter (PD), and estimated the pupil circularity under mesopic conditions. PD was also assessed under photopic, scotopic, pharmacological mydriasis, and miosis conditions. The results were compared to those of the fellow eye, phakic, or regular pseudophakic. RESULTS The IC-IOL and control groups included 30 eyes each. The most frequent reasons for IC-IOL implantation were complicated cataract (37%) and dislocated/luxated prior IOL (33%). Compared to the control group, the IC-IOL group had lower visual acuity, a smaller PD under scotopic conditions (p = 0.0010) and after pharmacological mydriasis (p < 0.0001), and a larger PD after pharmacological miosis (p < 0.0001). Mesopic pupil circularity was comparable between the groups. We also considered ongoing extraocular treatments with possible effects on iris motility. CONCLUSIONS The pupillary size and profile were similar between the groups in mesopic light. Reduced mydriasis was noted in response to light and drugs, while the degree of miosis was reduced in response to inducing drugs in the IC-IOL compared to the control group. This study complements previous results concerning the PC placement of IC-IOLs by adding original observations on drug-induced pupil motility.

Abstract
Early (< 3 months) intraocular lens (IOL) dislocation occurs due to insufficient fixation in the capsular bag, while late dislocation (≥ 3 months) is due to increasing insufficiency of the zonular apparatus. Iris-fixated IOL (IFIOL) and suture- or sutureless-fixated scleral IOL (SFIOL) are currently the most commonly used methods when IOL exchange is indicated. Different methods of scleral fixation with or without sutures have been described. The most important techniques are summarised in this paper. IFIOL and SFIOL allow comparable visual outcomes but differ in their risk profile. The decision of which method to use should be made case by case and in accordance with the surgeon's preference.

Trans-Scleral Plugs Fixated FIL SSF IOL: A Review of the Literature and Comparison with Other Secondary IOL Implants. J Clin Med 2023; 12:jcm12051994.

Abstract
Purpose. To revise the current literature on FIL SSF (Carlevale) intraocular lens, previously known as Carlevale lens, and to compare their outcomes with those from other secondary IOL implants. Methods. We performed a peer review of the literature regarding FIL SSF IOLs until April 2021 and analyzed the results only of articles with a minimum of 25 cases and a follow-up of at least 6 months. The searches yielded 36 citations, 11 of which were abstracts of meeting presentations that were not included in the analysis because of their limited data. The authors reviewed 25 abstracts and selected six articles of possible clinical relevance to review in full text. Of these, four were considered to be sufficiently clinically relevant. Particularly, we extrapolated data regarding the pre- and postoperative best corrected visual acuities (BCVA) and the complications related to the procedure. The complication rates were then compared with those from a recently published Ophthalmic Technology Assessment by the American Academy of Ophthalmology (AAO) on secondary IOL implants. Results. Four studies with a total of 333 cases were included for results analysis. The BCVA improved in all cases after surgery, as expected. Cystoid macular edema (CME) and increased intraocular pressure were the most common complications, with an incidence of up to 7.4% and 16.5%, respectively. Other IOL types from the AAO report included anterior chamber IOLs, iris fixation IOLs, sutured iris fixation IOLs, sutured scleral fixation IOLs, and sutureless scleral fixation IOLs. There was no statistically significant difference in the rates of postoperative CME (p = 0.20), and vitreous hemorrhage (p = 0.89) between other secondary implants and the FIL SSF IOL, whereas the rate of retinal detachment was significantly less with FIL SSF IOLs (p = 0.04). Conclusion. The results of our study suggest the implantation of FIL SSF IOLs is an effective and safe surgical strategy in cases where there is a lack of capsular support. In fact, their outcomes seem to be comparable to those obtained with the other available secondary IOL implants. According to published literature, the FIL SSF (Carlevale) IOL provides favorable functional results with a low rate of postoperative complications.

Abstract
BACKGROUND There is no standard for the treatment of functional aphakia in cases with a compromised capsular system. Retropupillary fixation of an Artisan iris-claw IOL ("Intraokularlinse") is one of the established procedures. OBJECTIVE Aim of this study was the evaluation of indications, visual and refractive long-term results and complication rates after retropupillary implantation of an iris-claw lens. MATERIAL AND METHODS This retrospective study comprised 366 eyes that received a retropupillary Artisan intraocular lens (IOL) in a single center between January 2009 and December 2019. The mean follow-up period was 249 days (8 months) ±516 days. RESULTS IOL dislocation (68%) was the most common reason for a retropupillary iris-claw implantation. Previous vitrectomy was a significant preoperative risk factor for IOL dislocation (p = 0.0001). Best corrected visual acuity improved from 0.65 ± 0.64 (logMAR) preoperatively to 0.57 ± 0.51 (logMAR) 4-6 weeks after the surgery. The mean deviation from the planned refraction was +0.40 ± 1.37 dpt and 73% of the patients had a deviation within ±1 dpt of the planned refraction. Relevant postoperative complications during the first 4 weeks were pupillary distortion (42%), ocular hypotony (15%) and transient hyphema (14%). Late complications (≥4 weeks after the surgery) included persistent pupillary distortion (20%), cystoid macular edema (13%) and iris-claw disenclavation (6%). CONCLUSION The retropupillary Artisan implantation is an efficient method for treating aphakia without capsular support and provides good visual and refractive results with an acceptable surgical risk profile.

Abstract
The aim of this multicenter, national clinical audit is to evaluate the predictive factors and management of postoperative macular edema (ME) after retropupillary iris-claw intraocular lens (RICI) implantation and pars plana vitrectomy (PPV). Preoperative, surgical and postoperative data were collected. Number and type of intravitreal injections (IT) administered (anti-VEGF or dexamethasone implant), visual acuity (VA), intraocular pressure (IOP) and central retinal thickness (CRT) assessed by OCT were collected at 1, 3, 6 and 12 months. From 325 eyes (325 patients), 11.7% (38/325) developed postoperative ME. Previous complicated cataract surgery with no capsular support was the only significant predictive factor for developing postoperative ME (OR 2.27, 95% CI 1.38-4.52, p = 0.02) after RICI implant. Mean time to ME development was 11.4 ± 10.7 weeks, and mean CRT peaked at 3 months follow-up. Different treatment options were non-steroidal anti-inflammatory (NSAIDs) drops (31.6%, 12/38), dexamethasone (DEX) implant (50%, 19/38), anti-VEGF (7.9%, 3/38) or combined IT (10.5%, 4/38). Cumulative probability of ME resolution was higher in the group treated with IT than in the group treated with topical NSAIDs (85.2% vs. 58.3%, p = 0.9). Performing RICI implantation after complicated cataract surgery is a risk factor for the development of postoperative ME. DEX implants may be an effective treatment for postoperative ME in these cases.

Abstract
Purpose To review current evidence regarding the use of iris-claw intraocular lens (IOL) in terms of its efficacy and safety in the population of pediatric ectopia lentis. Methods A comprehensive literature search of six electronic databases (PubMed-NCBI, Medline-OVID, Embase, Cochrane, Scopus, and Wiley) and secondary search through reference lists was conducted using keywords selected a priori. All primary studies on the use of iris-claw in pediatric ectopia lentis that evaluated visual acuity (VA), complications, and endothelial cell density (ECD) were included and critically appraised using the Newcastle-Ottawa Scale. Results Ten studies were eligible for inclusion with an overall sample size of 168 eyes of children with ectopia lentis, and the majority of studies evaluated anterior iris-claw IOL. All studies reported improvement in postoperative VA. The most commonly reported complication across studies was IOL decentration. All studies reported decreasing ECD, and this was observed in both anterior and retropupillary iris-claw IOL. Conclusion Current evidence shows that iris-claw IOL is effective in terms of improving VA in pediatric ectopia lentis. Due to the lack of long-term evidence of its safety in children, one must remain cautious regarding potential endothelial cell loss. Further high-quality, interventional, long-term studies are needed.

Abstract
Purpose To study the use of sulcus placement of a 3-piece intraocular lens (IOL) with optic capture in patients with exfoliation with zonular weakness. Methods Data on all exfoliation patients who had direct or indirect evidence of zonular weakness and had a 3-piece IOL implanted in the sulcus with optic capture over a 5-year period between January 2017 and January 2022 were included in this retrospective case series. Results The study comprised of 35 eyes of 35 patients. The mean age at surgery of the 20 male and 13 female patients was 75.21 years ± 5.74 (standard deviation (SD)). The mean pupillary diameter was 5.77 ± 2.23 mm (range: 10 to 3 mm). A capsular tension ring (CTR) was used in 17 cases and iris hooks as a pupil-expanding device were used in 15 cases. No patients had an increase in inflammation after surgery and there were no late subluxation or dislocation of "in the bag" posterior chamber IOL or major complications. There was a significant improvement in visual acuity. Conclusion The sulcus placement of 3-piece IOL with optic capture is the ideal technique in patients with clinical or intraoperative evidence of mild to moderate zonular weakness. It may also be more appropriate in relatively younger patients (in the fifties or sixties) with exfoliation with no overt zonulopathy to prevent late subluxation or dislocation of "in the bag" IOL.

Abstract
Despite the safety and efficacy of cataract surgery, intraoperative complications can hamper the ability to place an intraocular lens in the capsular bag. With vast numbers of cataract surgeries performed daily, complications occur often enough that every ophthalmologist should be equipped with techniques to manage aphakia. Medical management of aphakia used to be commonplace but these techniques have their disadvantages including thick bulky lenses, poor cosmesis, and aniseikonia. Surgical management of aphakia overcomes these disadvantages and offers patients the possibility of a spectacle and contact lens-free lifestyle. This article reviews the various options of surgical management of aphakia and their advantages and disadvantages. Comparison of outcomes between techniques and a protocol for deciding between techniques is presented.

Abstract
AbstractBackground: Complicated cataract surgery is the main cause of secondary lens implantation surgery. Several approaches have been introduced to face those circumstances. As it concerns scleral-fixated IOLs for the posterior chamber, many types of IOL can be implanted. The aim of article is to review the single piece sutureless scleral fixation Carlevale lens; Methods: Narrative review; Results: Several works described as safe the IOL implantation utilizing the handshake approach, without tactile manipulation, which allows for self-centration and lens firm fixation in uncomplicated surgery. This allows to reduce high order aberration such as astigmatism and coma, with a very good postoperative BCVA Conclusions: Carlevale lens is one of the best option to manage insufficient capsular support.

Abstract
Purpose The aim of this study was to evaluate a micrometer-accurate analysis of the retropupillary Verisyse® intraocular lens (IOL) (Ophtec, Groningen NL; Santa Ana, USA) enclavation in the iris tissue. Methods A retrospective consecutive case series was conducted at the Department of Ophthalmology, University Hospital Mainz. Patients with an optical coherence tomography (Spectralis®, Heidelberg Engineering®; Heidelberg, Germany) examination after retropupillary Verisyse® IOL implantation were included retrospectively. The enclavation geometry was measured using the Eye-Explorer® from Heidelberg Engineering® (Heidelberg, Germany). Seventeen measuring positions were determined nasally and temporally at the corresponding enclavation points. Results 72 eyes of 67 patients after implantation of a retropupillary Verisyse® IOL were analyzed. The average age was 68 ± 17.2 years (63% female; 38% male). The analysis of the position of the Verisyse® IOL showed highly homogeneous data in all measured points. The depth of the anterior chamber showed a positive correlation with width of the posterior deflection of the iris tissue behind the enclavation (Pearson r: 0.321, p=0.041). The offset of the haptics showed greater deviations, and the lens diopter implanted was higher (r = 0.337, p=0.007). Conclusion This is the first study that analysis the exact enclavation of retropupillary implanted Verisyse® IOL. It provides new information about the intrastromal course of the haptics in the iris tissue. It could be shown that the haptics do not run parallel in the iris tissue, but are anchored in the iris tissue with an average offset of 95 µm. This rebuts previous assumptions about the intrastromal course and provides new information.

Abstract
PURPOSE To report 12-month visual outcomes, incidence of intraocular pressure (IOP) changes and postoperative complications after pars plana vitrectomy with retropupillary implantation of an iris claw intraocular lens (IOL) in aphakic eyes after complicated cataract surgery and eyes with a dislocation of the IOL. METHODS This is a retrospective analysis of eyes undergoing implantation of an iris claw IOL combined with pars plana vitrectomy from 1st of January 2009 until 30th of June 2018 after complicated cataract extraction with capsular loss (Group A) or dislocation of an IOL (Group B). Corrected distance visual acuity was analyzed in logarithm of the minimum angle of resolution (logMAR) units, IOP was recorded in mmHg. RESULTS Eyes in Group A (n = 49) improved from a preoperative median visual acuity of 0.523 logMAR (Snellen 20/65) to 0.201 logMAR (Snellen 20/30), P < 0.01. Eyes in Group B (n = 126) showed stable median visual acuity, preoperative 0.301 logMAR (Snellen 20/40) versus postoperative 0.222 logMAR (Snellen 20/30), P > 0.05. During 12 months in Group A, IOP >21 mmHg occurred in 9 (18.4%) eyes; no eye had an IOP <6 mmHg. In Group B, IOP >21 mmHg occurred in 15 (11.9%) eyes, IOP <6 mmHg in 5 (4%) cases. None of the eyes in Group A and B had IOP >21 mmHg or <6 mmHg at 12 months follow-up. CONCLUSION The retropupillary implantation of an iris claw IOL with pars plana vitrectomy provides adequate visual rehabilitation and seems to be safe in IOP changes.

Abstract
INTRODUCTION The correction of aphakia when there is no adequate capsular support remains a therapeutic challenge. The use of retroiridial fixation lenses has been extended given their lower complication rate compared to other available options. MATERIAL AND METHODS Retrospective study including all cases operated with an Artisan® retropupillary aphakia implant. RESULTS 33 eyes were included out of a total of 28 patients. The follow-up period has been 38.55 months (1-96). 32.3% had a lens dislocation and 67.7% had an intraocular lens dislocation. The previous mean best corrected visual acuity (BCVA) was 1.18 ± 0.79 logMAR and post-intervention 0.36 ± 0.62 (p < 0.01). 93.8% of the patients presented a final BCVA equal to or better and 62.5% an improvement of 3 or more lines. The most frequent complication was corectopia (31.3%) and hypotony in the immediate postoperative period (21.9%). An epiretinal membrane (ERM) developed in 18.8% and cystic macular oedema (CME) in 9.4%. The presence of complications in the postoperative period did not statistically influence the final BCVA. CONCLUSIONS The retropupillary Artisan® lens allows the correction of aphakia with satisfactory visual results and a low rate of complications.

Tilt and decentration of posterior and anterior iris-claw intraocular lenses: a pilot study using anterior segment optical coherence tomography. BMC Ophthalmol 2022; 22:233. [PMID: 35606746 PMCID: PMC9125863 DOI: 10.1186/s12886-022-02430-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 04/29/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Information on the centration and tilt of iris-claw intraocular lenses (IC-IOLs) is limited. In this study, we tested the capacity of an anterior segment optical coherence tomography (AS-OCT) instrument to measure decentration and tilt of anterior and posterior IC-IOLs through an integrated software. METHODS The present observational, cross-sectional study was conducted at University Eye Clinic of Parma (Parma, Italy). The CASIA2 swept-source AS-OCT (Tomey Corp.) was used to measure the tilt and decentration of posterior and anterior IC-IOLs in patients implanted at least 6 months in advance. After failure with full-automation, semi-manual IOL tracing was applied. In-the-bag (IB) contralateral IOLs, when present, were measured automatically. The Bland-Altman method was used to evaluate the agreement between repeated measurements (2 images for each study eye). The amount and direction of tilt and decentration were recorded and plotted into polar charts for evaluation. RESULTS A total of 21 patients were included: 14 with posterior and 7 with anterior IC-IOL fixation. In 17 eyes (81%), the AS-OCT provided a repeatable measurement of tilt and decentration. All contralateral eyes with IB IOL were automatically measured. The median decentration was 0.67 mm, 0.24 mm, and 0.24 mm in posterior IC-IOLs, anterior IC-IOLs, and IB IOLs group, respectively. The median tilt was 5.0°, 5.6°, and 5.6° for posterior IC-IOLs, anterior IC-IOLs, and IB IOLs, respectively. Tilt direction was mainly temporal, while decentration was inferior-temporal with posterior IC-IOLs and scattered with anterior IC-IOLs and IB IOLs. CONCLUSIONS The semi-manual tracing function of the CASIA2 AS-OCT provides repeatable and affordable measurements of the decentration and tilt of IC-IOLs in both the anterior and posterior chamber. Data from the former group were similar to the IB group.

Abstract
Introduction To describe the outcomes of retropupillary iris fixation of an iris claw Artisan Myopia intraocular lens (IOL), and to review literature on retropupillary iris fixation of iris claw models for myopia for the correction of aphakia and IOL dislocation in eyes with extremely high myopia. Methods Single-center, retrospective case series. Three patients (three eyes) with pathological myopia underwent retropupillary iris fixation of the iris claw Artisan Myopia model 204 for the correction of aphakia and IOL dislocation. After IOL power calculation, we found that the Artisan Aphakia IOL was not available for these patients. One patient had a history of previous extracapsular cataract extraction and two patients exhibited IOL–bag complex dislocation. The target lens power was calculated using ultrasound biometry and the Sanders–Retzlaff–Kraff theoretical and T2 formulae, with an A-constant of 103.8. All surgeries were performed by a single surgeon. Visual outcomes were assessed at 12–48 months after surgery. Results The mean axial length was 34.33 ± 0.21 mm. The power of the implanted Artisan IOLs ranged between − 4.00 and − 3.00 diopter. The corrected distance visual acuity, measured in logarithm of the minimum angle of resolution units, improved after surgery in all eyes, from 0.60 ± 0.36 logMAR before surgery to 0.40 ± 0.43 logMAR after surgery at 12 months postoperatively and remained stationary thereafter. There were no postoperative complications. Conclusions Retropupillary iris fixation of Artisan Myopia IOLs may be a safe and effective surgical treatment option for the correction of aphakia and IOL dislocation in patients with extremely high myopia.

Abstract
Iris-claw lenses have gained increasing popularity over the last years and are by many surgeons regarded as viable options in eyes with insufficient capsular or zonular support. The iris-claw lens has two haptics with fine fissures for folding (enclavating) the mid-peripheral part of the iris stroma and can either be placed in front of or posterior to the iris. In particular, the retropupillary implantation has been increasingly chosen probably due to having an anatomical position similar to that of the crystalline lens. The present review is based on a literature review and also on the authors' clinical experience with this lens, and it focuses on surgical techniques and outcomes especially related to the characteristics of this lens, having haptics with claws that fixate the lens to the posterior iris. Implanting retropupillary iris-claw lenses has a relatively short learning curve, and there are only few complications reported during surgery. Retropupillary iris-claw lenses have demonstrated generally favourable efficiency and safety. However, the outcomes are probably more influenced by the reason for surgery and eye comorbidity than the lens itself. Albeit seldom reported, the postoperative complications have mostly been related to atrophy of the iris at the site of the haptics, or IOL decentration or disenclavation of one of the haptics. To date, however, there are few randomized clinical trials comparing this lens to other lens alternatives in eyes exhibiting insufficient capsular or zonular support for placing the lens in the ciliary sulcus. In the future, prospective studies with large samples should be performed to gain insights into the long-term safety of retropupillary placed iris-claw lenses, and for comparisons with the various other techniques of lens fixation.

Abstract
An Intraocular Lens (IOL) fixated on the iris either anteriorly, as a phakic IOL, or posteriorly, as an aphakic IOL, can influence pupil motility. In this interventional case series study, we evaluated pupil size under different levels of illumination (scotopic = 0.04 lx, low-mesopic = 0.4 lx and high-mesopic = 4 lx) for anterior iris-claw IOL fixation for correcting myopia or hyperopia (IFPH), retropupillary iris-claw IOL fixation to correct aphakia or as treatment for late in-the-bag IOL dislocation/subluxation (IFRP), and capsular-fixation IOL in-the-bag implantation (IB). Pupil size was measured preoperatively for the IFPH- and IB-group as well as 6 months after surgery for all groups. We analyzed a total of 70 eyes: 22 eyes of 11 patients with phakic IOLs, 22 eyes of 20 patients in the IFRP group and 26 eyes of 13 patients in the IB group. Both IFPH and IB showed a smaller postoperative scotopic pupil size, compared with the preoperative values. When compared to postoperative values of IB and IFPH, IFRP showed a significantly smaller postoperative scotopic pupil size (IFPH: 5.89 ± 0.83 mm, IFRP: 4.37 ± 0.83 mm, IB: 5.34 ± 0.98 mm, p < 0.001) while no differences were seen at high-mesopic lighting. Neither of the surgical techniques seems to impair the constriction of the pupil.

Abstract
PURPOSE: The purpose of this study was to compare the long-term efficacy and safety of posterior iris-claw lens and scleral-fixated posterior chamber lens for aphakia after traumatic posterior dislocation of the crystalline lens. MATERIAL AND METHODS: Out of 120 evaluated cases, 60 were randomly assigned in each group. A 23G vitrectomy was done and intraocular lens was implanted by two different techniques. Extensive preoperative and postoperative evaluation was performed including optical coherence tomography and Scheimpflug imaging. Follow-up was done on days 1, 7, and 28 at 3 months, 6 months, and 12 months. RESULTS: A significant improvement was found in uncorrected visual acuity in both the groups. Surgical time in iris fixation was significantly less (P < 0.001), whereas pupil peaking and pigment release were more. Difference in mean intraocular pressure and change in astigmatism in both the groups were insignificant. CONCLUSION: Both the techniques had similar good visual results. Although operating time was shorter for iris fixation, it had several disadvantages, including immediate postoperative inflammation and ovalling of the pupil. However, scleral fixation had a better outcome in terms of postoperative complications.

Visual acuity, intraocular pressure, and central retinal thickness assessed by optical coherence tomography were collected at 1, 3, 6, and 12 months after surgery. Kaplan-Meier curves were created to assess the cumulative probability of postoperative visual acuity and intraocular pressure levels, macular edema development, and corneal decompensation. RESULTS The cumulative probability of the final visual acuity ≤0.3 logarithm of the minimum angle of resolution (≥20/40 Snellen) was 75.6% at 12-month follow-up. The probability of intraocular pressure >21, ≥25, and ≥30 mmHg was 48.1%, 33.1%, and 19.0%, and the probability of intraocular pressure-lowering drops was 50.9% at 12 months. Glaucoma surgery was required in 4.3% of the eyes (14/325). The cumulative probability of macular edema was 20.5% at 12 months and was greater in complicated cataract surgery than in intraocular lens-luxation eyes (26% vs. 16.7%, P = 0.04). Corneal transplantation was required in 2.8% of the eyes (9/325). CONCLUSION This study on 325 eyes with aphakia or intraocular lens dislocation managed with the retropupillary iris-claw intraocular lens technique provides clinical outcomes in a real-world scenario, reporting relevant data for patient counseling and preoperative discussions.

Supporting IOL'S in a Deficient Capsular Environment: The Tale of No "Tails". J Ophthalmol 2021; 2021:9933486. [PMID: 34557313 PMCID: PMC8455193 DOI: 10.1155/2021/9933486] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 08/18/2021] [Indexed: 11/18/2022] Open
Abstract
Purpose To evaluate the efficacy and safety of the following three distinct surgical procedures for secondary IOL implantation without capsular support: Iris-claw lens, flanged transscleral fixated IOLs (Yamane technique), and sutureless transscleral hook IOL fixation (Carlevale IOL). Materials and Methods In this retrospective comparative study, three different sutureless IOL implantation techniques were compared in patients without any capsular support. Visual acuity and outcomes were analyzed in 24 eyes of 23 patients (14 male and 9 female). Study included 13 iris-claw lenses (Artisan Ophtec), 6 flanged transscleral fixated IOLs (Yamane technique using a MA60MA Alcon Inc IOL), and 5 transscleral Carlevale IOLS (Carlevale IOL, Soleko, Italy). Results logMAR mean best-corrected visual acuity (BCVA) improved from 0.49 ± 0.19 to 0.19 ± 0.10 at three months after surgery (p < 0.05). Postoperative BCVA was similar in all three groups, and no intergroup difference was noted. Three eyes (12.5%) had a raised IOP >25 mmHg, 2 eyes (8%) presented a subluxated/dislocated IOL, 4 eyes (16%) had corneal edema longer than 7 days, 3 eyes (12.5%) had irregular pupil profile, 2 eyes (8%) had vitreous hemorrhage, 7 eyes had (29%) corneal astigmatism over 3 diopters, and one patient (4%) developed cystoid macular edema (CME). Conclusions All three surgical procedures can be considered adequate to correct aphakia in patients without capsular support with significant improvement in visual acuity and low complication.

Abstract
A 58-year-old woman presented to us with sudden onset diminution of vision for 10 days following trauma while using mobile phone. Patient had a history of posterior iris claw implantation 3 years ago. On examination, the patient was aphakic and intraocular lens (IOL) was seen enclaved on nasal side and disenclaved on temporal side on ultrasound biomicroscopy. Patient underwent surgery for re-enclavation of temporal haptic by lifting the IOL using 23-gauge pars plana trocar. Patient had a postoperative uncorrected visual acuity of 6/9 and best-corrected visual acuity of 6/6 with refraction. Re-enclavation of partially disenclaved posterior iris claw lens is a minimally invasive technique to restore visual acuity in such cases.

Abstract
Purpose To evaluate refractive outcomes after retropupillary iris-claw intraocular lens (IOL) implantation and to compare postoperative astigmatism from (1) a conventional 5.5-mm sclerocorneal incision, (2) an L-shaped scleral tunnel incision, and (3) a frown scleral tunnel incision. Methods This was a retrospective study of eyes undergoing dislocated IOL exchange for a retropupillary iris-claw IOL. Uncorrected and corrected distance visual acuity (UDVA and CDVA) and postoperative complications were evaluated until postoperative months 24. The refractive outcomes and the surgically induced astigmatism (SIA) vector were compared between groups. Results The medical records of 107 eyes from 107 patients with mean age of 65.31 ± 12.15 years were reviewed. Eyes with a frown incision showed the best UDVA, followed by those with L-shaped and conventional incisions (P = 0.003). Eyes with an L-shaped incision or frown incision had a lower SIA than that of the conventional incision group at postoperative 6 months (mean ± standard deviation [SD] SIA, 0.86 ± 0.85 D, 0.63 ± 0.37 D, and 1.70 ± 1.27 D for frown incision, L-shaped incision, and conventional incisions, respectively; P = 0.004). Conclusion The frown incision and L-shaped incision induced a significantly smaller SIA than the conventional incisions, which was associated with better UDVA postoperatively.

MEDICINA (KAUNAS, LITHUANIA) 2021; 57:785. [PMID: 34440990 PMCID: PMC8398260 DOI: 10.3390/medicina57080785] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 07/24/2021] [Accepted: 07/27/2021] [Indexed: 11/17/2022]
Abstract
Background and Objectives: Iris-claw intraocular lens (ICIOL) could be implanted in the anterior chamber (AC) or retropupillary (RP) in eyes lacking capsular and/or zonular support. Several studies have focused on comparing the efficacy and complications of these two techniques and we designed this research to review the published literatures. Materials and Methods: Peer-reviewed studies were collected through network databases (PubMed, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov) and analyzed. The primary outcome was the standardized mean differences (SMDs) of pre- and post-operative corrected distant visual acuity (CDVA). The secondary outcome was the SMDs of pre- and post-operative intraocular pressure (IOP), endothelial cell counts (ECC), and the odds ratios (ORs) of post-operative IOP elevation and cystoid macular edema (CME). Comprehensive Meta-Analysis software was utilized to conduct statistical analysis. Results: Six studies (one randomized controlled trial and five retrospective case series) were relevant and included a total of 516 eyes (255 and 261 eyes in the AC ICIOL and RP ICIOL groups, respectively). The quantitative analysis showed no significant differences in CDVA (SMD: 0.164, 95% confidence interval (CI): -0.171 to 0.500), ECC (SMD: -0.011, 95% CI: -0.195 to 0.173), and IOP elevation events (OR: 0.797, 95% CI: 0.459 to 1.383). Lesser IOP reduction (SMD: 0.257, 95%CI: 0.023 to 0.490) and a relative increase in the incidence of CME (OR:2.315, 95% CI: 0.950 to 5.637) were observed in the AC ICIOL group compared with RP ICIOL group. Conclusions: Our meta-analysis indicated that AC and RP ICIOL seem to have equivalent visual outcomes. RP ICIOL may perform slightly better with more IOP reduction and lesser CME. More randomized controlled trials, which have higher patient participation and more outcomes are needed to confirm our conclusions.

Abstract
PURPOSE Iris claw intraocular lenses (IOLs) were successfully used for the management of aphakia in patients that lack capsular support. The aim of this study was to compare the clinical outcome of prepupillary and retropupillary implantation of these IOLs. METHODS The files of the 26 patients that had an iris claw IOL implantation between 2010 and 2020 were retrospectively reviewed. Detailed ophthalmological examination findings including corrected distance visual acuity (CDVA), intraocular pressure, endothelial cell counts, slit lamp and dilated fundus examination findings were specifically tabulated. Intraoperative and postoperative complications were also specifically recorded. RESULTS There were 18 patients in the prepupillary implantation group and eight patients in the retropupillary implantation group. Age and gender distribution were similar between the groups. CDVA significantly increased in prepupillary and retropupillary implantation groups (p = 0.001 and p = 0.012, respectively). Median endothelial cell loss was 6.7% in prepupillary group and 7.2% in retropupillary group. The only intraoperative complication was iridodialysis (n = 1). Postoperative complications included retinal detachment (n = 1), cystoid macular edema (n = 2) and IOL tilt (n = 1). All of these complications occurred in the prepupillary implantation group. CONCLUSION Prepupillary and retropupillary implantation of iris claw IOLs resulted with similar visual gain and endothelial loss rates in a follow-up time of 6 months. There was an insignificant trend toward a reduced complication rate following retropupillary implantation.

Abstract
BACKGROUND To compare the clinical features and long-term treatment outcomes of patients undergoing secondary intraocular lens (IOL) surgery with scleral-fixated (SFIOL) versus retropupillary iris-claw IOL (RPICIOL). METHODS Consecutive patients treated between June 2014 and December 2019 at two tertiary centres were retrospectively reviewed. The primary outcome was the best-corrected visual acuity (BCVA). Secondary outcomes included factors associated with significant corneal endothelial injury and postoperative redislocation. RESULTS This study included 395 eyes undergoing surgery with SFIOL (237 eyes, 60%) or RPICIOL (158 eyes, 40%), with no differences in baseline BCVA (p = 0.76) or endothelial cell density (ECD) (p = 0.39). Compared with the SFIOL group, the RPICIOL group had faster visual recovery (postoperative month 1, 20/37 vs. 20/46, p = 0.005) sustained to over 36 months (p = 0.034), favourable absolute prediction errors (within 0.5D, 67.3% vs. 54.9%, p = 0.027), and shorter operation times (52.7 vs. 60.9 min, p = 0.015). There was no difference in ECD after 12 months (P = 0.282). Over a mean follow-up duration of 33 months (152 cases >3 years, 38.5%), the SFIOL group experienced more cases of tilted/decentred IOLs (14 vs. 1, p = 0.006), suture exposure (7 vs. 0, p = 0.045), and redislocation (17.7% vs. 10.1%, p < 0.001). Multivariable regression showed that a final BCVA below 20/40 was associated with SFIOL (P = 0.007), older age (p = 0.001), intraoperative complications (p = 0.002), past history of vitrectomy/glaucoma surgery or uveitis (p = 0.046), and surgically induced astigmatism >1D (p = 0.029). CONCLUSIONS RPICIOL appears to be a safe and effective surgical option for secondary IOL surgery over a long-term follow-up, comparing favourably against conventional SFIOL.

Abstract
Retropupillary iris-claw intraocular lenses (ICIOLs) have been increasingly chosen by surgeons nowadays as a primary or secondary procedure of IOL implantation in eyes with insufficient capsular or zonular support. They have gained popularity due to their simple fast technique, favourable functional outcomes, and safety. The transition in the ICIOL fixation from prepupillary to a more biologically appropriate retropupillary position and change in the optic design from biconvex to convex-concave have provided better visual outcomes and improved safety. A peer-reviewed literature search was conducted in Medline (PubMed), Embase, and Cochrane Library using the keywords "retropupillary iris claw" and "iris claw". The search yielded 310 articles that were screened. Forty-three articles on retropupillary ICIOLs were finally found to be relevant and reviewed in full-text versions. The functional outcomes following retropupillary implantation of ICIOLs have been acceptable in eyes with no ocular co-morbidities otherwise. However, the indications for surgery may affect the outcomes. The major postoperative complications directly associated with ICIOLs include pupil ovalization and redislocation. Nevertheless, the rate of disenclavation depends on the experience and skill of the surgeon. This review is based on a literature review, and it focuses on the preoperative evaluation, surgical technique, postoperative outcomes, and associated complications. Prospective randomized trials with a larger sample size and longer follow-up are needed for comparison with other techniques of IOL fixation and confirmation of long-term safety profile.

Abstract
Cataract surgery via phacoemulsification with intraocular lens (IOL) placement in the capsular bag is the gold standard in the presence of adequate capsular support. However, when capsule and/or zonular fibers are weak or absent, alternate fixation strategies are required. Common alternative options include retropupillary iris-claw IOLs (RP-IC IOLs) and scleral-fixated IOLs (SF IOLs). In the present review of 87 articles with 2174 eyes implanted with RP-IC IOLs and 2980 eyes with SF IOLs, we discuss the published literature with respect to safety and efficacy. Although the studies reporting outcomes of these IOLs have been performed in patients with different concomitant conditions, visual and refractive outcomes were found to be comparable between RP-IC IOLs and SF IOLs. RP-IC IOL implantation seemed to provide equivalent or a potentially lower rate of complications than SF IOL implantation. Data from the literature also suggest that the surgical technique of RP-IC IOL implantation is relatively simpler with correspondingly shorter surgical times.

Abstract
Background. The management of patients with aphakia and/or lack of capsular support remains debated. The sutureless posterior chamber IOL (PCIOL) fixation is a very useful surgical option. The purpose of the study was to compare the early outcomes as well as post-operative best corrected visual acuity, refractive errors and complications of two different techniques of sutureless PCIOL secondary implantation. Methods. Patients who underwent secondary implantation from December 2019 to January 2021 in the Department of Ophthalmology of Creteil Hospital, and in the Granville Ophthalmology Center, were retrospectively included. Eyes implanted with the iris claw lens (Artisan Aphakia IOL model 205, Ophtec BV, Groningen, The Netherlands) were included in group 1, and eyes implanted with a newly developed sutureless trans-scleral plugs fixated lens (STSPFL, Carlevale lens, Soleko, Pontecorvo, Italy) were included in group 2. Results. Twenty-two eyes of 22 patients were enrolled in group 1, and twenty eyes of 20 patients in group 2. No difference was found in visual acuity between two groups (0.35 +/− 0.29 logmar for group 1 and 0.23 +/− 0.51 logmar for group 2) (p = 0.15) at mean post-operative follow up (6.19 +/− 3.44 months for group 1 and 6.42 +/− 3.96 months for group 2) (p = 0.13). Both the mean refractive error (MRE) and induced astigmatism (IA) were greater in group 1 compared to group 2, respectively: the MRE was 0.99 +/− 0.57 vs. 0.46 +/− 0.36 (p < 0.01), and IA was 1.72 +/− 0.96 vs. 0.72 +/− 0.52 (p < 0.01). Conclusions. No significant differences in terms of the recovery of visual acuity were found between the two groups. Group 2 (STPFL) gives better results in our sample due to less post-operative induced astigmatism and less refractive error.

Abstract
Purpose: To evaluate the outcomes of implantation of an iris-claw intraocular lens (IC-IOL) in retropupillary position in aphakic patients. Methods: We conducted a prospective interventional study, including 36 aphakic eyes with inadequate capsular support. The postoperative examination included best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central corneal thickness (CCT), and anterior segment examination with emphasis on the anterior chamber reaction and shape of pupil. Follow-up was done for 3 months. Results: Thirty-six eyes of 34 patients, including 22 right eyes and 14 left eyes were included. Indications for surgery were complicated cataract surgery in 38.9% (n = 14), aphakia in 27.8% (n = 10), pseudophakic bullous keratopathy in 16.7% (n = 6), dislocated posterior chamber IOL (PCIOL) in 11.1% (n = 4), IC drop in 2.8% (n = 1), and subluxated PCIOL in 2.8% (n = 1). Postoperatively, the visual acuity improved by at least two lines in 32 (88.9%) and worsened in four (11.1%) eyes at the end of three months. Mean postoperative IOP at the end of the third month was 12.42 mmHg (standard deviation [SD] 2.57; range 11.55–13.29 mmHg). The mean postoperative CCT at the end of the third month was 542.42 microns (SD 13.77; range 537.76–547.07 microns). Sixteen eyes (44.4%) had horizontally oval pupil, eleven eyes (30.6%) had round pupil, and nine eyes (25%) had irregular pupil. Twenty-three eyes (63.9%) presented with significant anterior chamber reaction and seven eyes (19.4%) had corneal stromal edema on postoperative day 1. Conclusion: Our study demonstrated that retropupillary IC-IOL implantation in eyes without adequate capsular support is an effective and safe procedure with a good visual outcome and fewer complications.

Abstract
We aimed to investigate the efficacy and safety of primary retropupillary iris claw intraocular lens (R-IOL) implantation in patients with complete intraocular lens (IOL) dislocation. In this single-center retrospective case series, we reviewed the medical records of patients who underwent R-IOL implantation surgery with pars plana vitrectomy for the treatment of IOL dislocation between September 2014 and July 2019. The primary outcome was change in visual acuity (VA) up to 24 months postoperatively. The secondary outcomes included changes in intraocular pressure (IOP), refractive errors, and endothelial cell count (ECC) over the same period. Data of 103 eyes (98 patients) were analyzed. The mean uncorrected VA was significantly improved at one month postoperatively (− 0.69 logMAR, P < 0.001), compared to the preoperative value. IOP (− 2.3 mmHg, P = 0.008) and ECC (− 333.4 cells/mm2, P = 0.027) significantly decreased one month post-surgery and remained stable thereafter. Postoperative mean spherical equivalents were similar to the prediction error throughout the follow-up period. IOP elevation (n = 8, 7.8%), cystoid macular edema (n = 4, 3.9%), and dislocation of the R-IOL (n = 10, 9.7%) were managed successfully. Overall, primary R-IOL implantation with pars plana vitrectomy is effective and safe for correcting IOL dislocation due to various causes.

Abstract
PURPOSE To report clinical outcomes of retropupillary iris-suture-fixated rigid intraocular lens (IFIOL) SETTING: Tertiary care ophthalmic hospital DESIGN: Retrospective study METHODS: This study included all eyes undergoing IFIOL with a minimum follow-up of 6 months between April 2017 and January 2019. Patients with preexisting anterior or posterior segment pathologies causing defective vision, uveitis or history of previous intraocular surgeries with exception of cataract surgery were excluded from the study. Data were retrieved from electronic medical records, and we documented demographics, history, position of cataractous lens or IOL, primary/secondary surgery and its complications. Postoperative visual acuity, pupillary response, diplopia, centration of IOL, inflammation were also recorded at the baseline visit and at 1 month, 3 months and 6 months postoperatively. RESULTS One hundred and ten eyes of 110 patients that underwent IFIOL were evaluated. Twenty-two patients (20%) underwent primary IFIOL, whereas 67 (60.9%) patients had secondary IFIOL. In 18 patients (16.36%), IFIOL was done to reposition decentered/dislocated IOLs. At the final follow-up, there was a significant improvement in corrected distance visual acuity (CDVA) with 87 patients (79.09%) achieving CDVA of 6/12 or better. IFIOL was stable and centered in 101 eyes (91.81%). Two patients (1.81%) had intraoperative complications. Postoperative iritis was seen in 7 patients (6.36%), and 4 patients (3.63%) had rise in IOP. CONCLUSION This is a safe, reliable, reproducible technique for aphakia rehabilitation and decentered IOL stabilization with good clinical outcome, especially in a limited resource setting.

Abstract
The review discusses modern problems of intraocular lens (IOL) exchange. Making an adequate choice between IOL reposition and IOL exchange in pseudophakic patients with problems of lens fixation remains a largely unsolved issue. The literature data shows a noticeable increase in the number of supporters of retropupillary fixation of an iris-claw lens during the exchange procedure.

Abstract
OBJECTIVE OF SURGERY The aim is the explantation of an intraocular lens (IOL) due to dislocation into the vitreous cavity with subsequent secondary implantation of a retropupillary iris claw IOL via the pars plana without creating a large corneal incision. The aim of the operative technique is to avoid corneal astigmatism after secondary IOL implantation, faster recovery of visual acuity and reduction of invasive maneuvers in the anterior chamber. INDICATIONS The surgery is indicated by an in-the-bag dislocation of a posterior chamber lens into the vitreous cavity without the possibility of refixation due to zonulopathy. CONTRAINDICATIONS Contraindications are extensive iris stromal defects, iritis, scleromalacia, ischemic retinopathies. SURGICAL TECHNIQUE The technique consists of explantation of the IOL during a standard pars plana vitrectomy (20 gauge) with an extended sclerotomy and subsequent secondary implantation of a retropupillary iris claw IOL using the same sclerotomy. The operation video is available online. FOLLOW-UP Treatment is carried out with local steroids and antibiotic eyedrops for 3 weeks. In the case of a corneal suture, removal is recommended after 14 days. EVIDENCE The implantation of a retroiridal iris claw lens is an established procedure. The introduction via the pars plana in the presented form is a first description.

Abstract
ZusammenfassungEs stehen verschiedene alternative chirurgische Optionen zur Verfügung, um eine sekundäre Intraokularlinse (IOL) in Augen mit unzureichender Kapselunterstützung zu implantieren. Erfolgreiche Techniken umfassen die Implantation einer irisfixierten IOL (IFIOL), einer kammerwinkelgestützten Vorderkammerlinse (ACIOL) oder verschiedene Variationen zur Sklerafixierung (SFIOL). Jede dieser Methoden hat sich als sicher und effektiv erwiesen, weist jedoch verfahrensspezifische Einschränkungen auf. Jüngste Studien zeigen, dass die Entwicklung neuer chirurgischer Techniken diesen Patienten weiterhin sichere und reproduzierbare Behandlungsmöglichkeiten bietet. Obwohl die Implantation von sekundären IOLs ohne Kapselunterstützung von vielen Faktoren, einschließlich der Präferenz des Chirurgen, abhängt, sind nahtlose sklerafixierende Techniken für die chirurgische Gemeinschaft von wachsendem Interesse. Das Bestreben nach kürzeren und weniger traumatischen Operationen sowie nach reproduzierbaren und funktionell guten Ergebnissen, fördert dabei die Entwicklung von neuen Operationstechniken, Intraokularlinsen und Instrumenten. Diese Übersichtsarbeit gibt einen Einblick in alte und neue Behandlungsmethoden zur Korrektur von Aphakie mit sekundären Intraokularlinsen

Abstract
PURPOSE To describe practical approaches to the management of subluxed or dislocated intraocular lenses (IOL) in patients with uveitis. PATIENTS AND METHODS Retrospective case series from a specialist uveitis clinic. RESULTS Fifteen IOLs in 13 patients were subluxed inferiorly (12) or dislocated into anterior chamber (2) or vitreous (1) at a mean delay of 12 years after cataract surgery. Six eyes required vitrectomy and seven IOL explantation. A dislocated IOL was repositioned by scleral fixation in one, and a new IOL was implanted in three (two scleral-sutured, one iris-claw). Eight were observed without surgery and 7 were left functionally aphakic (4 corrected with contact lens). The mean final best-corrected visual acuity was 0.6 LogMAR. CONCLUSIONS There are several management choices for IOL dislocation which should take into account the degree of uveitis, patient age and expectations. We present a pragmatic approach: surgery can often be avoided in this high-risk group.

Abstract
PURPOSE To review the published literature on the visual acuity results and complications of different surgical techniques for intraocular lens (IOL) implantation in the absence of zonular support. METHODS Peer-reviewed literature searches were conducted last in PubMed and the Cochrane Library in July 2019. The searches yielded 734 citations of articles published in English. The panel reviewed the abstracts of these mostly retrospective case series studies, and 45 were determined to be relevant to the assessment objectives. Three articles were rated as level II evidence, and 42 articles were rated as level III evidence. RESULTS Eight different types of IOL fixation techniques with at least 6-month follow-up were evaluated: anterior chamber IOL (ACIOL), iris-claw IOL, retropupillary iris-claw IOL, 10-0 polypropylene iris-sutured posterior chamber IOL (PCIOL), 10-0 polypropylene scleral-sutured PCIOL, 8-0 polypropylene scleral-sutured PCIOL, CV-8 polytetrafluoroethylene, and intrascleral haptic fixation (ISHF). Eight articles reported data comparing 2 techniques. The 45 studies had insufficient statistical power to compare the techniques conclusively. A qualitative analysis of similar types showed that trends in visual acuity outcomes were not inferior to those of ACIOL implantation, but the severity of preoperative pathologic features was not controlled for. Compared with ACIOL, complications of cystoid macular edema were higher in 10-0 polypropylene iris-sutured PCIOL and 8-0 polypropylene scleral-sutured PCIOL. Non-anterior chamber IOL techniques were less likely to report chronic uveitis. Chronic glaucoma was highest in the 8-0 polypropylene scleral-sutured PCIOL group. Although retinal detachment was infrequent overall, it was twice as common in both iris- and scleral-sutured PCIOLs (except CV-8 polytetrafluoroethylene suture) compared with nonsutured methods: ACIOL, iris-clipped IOL, and ISHF PCIOL. CONCLUSIONS The evidence reviewed shows no superiority of any single IOL implantation technique in the absence of zonular support. The various techniques seem to have equivalent visual acuity outcomes and safety profiles. Each technique has its own profile of inherent risk of postoperative complications. Surgeons must educate patients on the importance of close, long-term follow-up as a result of the uncertain nature of these techniques. Large prospective studies are needed to confirm the long-term complication profiles of these various IOL implantation techniques.

Abstract
Purpose To compare the visual outcome and complications of retropupillary fixated iris claw intraocular lens (IOL) and sutureless intrascleral IOL fixation using the flanged fixation technique at 1 year. Methods In this retrospective study, eyes that underwent either iris claw or flanged SFIOL from January 2016 to July 2017 with a minimum of 1-year follow-up were enrolled. Improvement in visual acuity, intraocular pressure measurements, endothelial cell count, central macular thickness, and complications were compared between and within groups at 6 weeks, 3 months, and 1 year postoperatively. Results Data from 150 eyes were analyzed (n = 90 in the iris claw group and n = 60 in the flanged SFIOL group). Posterior capsular rent was the most common indication for IOL implantation (n = 51, 34%). The iris claw and SFIOL groups were comparable in terms of demographics and baseline characteristics. There was significant improvement in uncorrected distance visual acuity (UCDVA) at 6 weeks in both groups (P = 0.77), and at 1 year, the UCDVA was comparable between groups (0.36 ± 0.32 in the iris claw group and 0.30 ± 0.28 in the SFIOL, P= 0.75). Transient elevation of intraocular pressure was seen slightly more in eyes with SFIOL (17%), while ovalization of the pupil was the main sequelae seen in the iris claw group (20%). Conclusion Both iris claw IOL fixation and SFIOL using flange are viable options for surgical correction of aphakia. Visual outcomes are excellent at 6 weeks and are maintained till 1-year follow-up, and complication rates are acceptably low, although ovalization of pupil is common with iris claw IOLs.

Abstract
A male patient, 63 years of age, presented with dislocation of a retropupillary fixated iris claw lens due to nasal haptic disenclavation. During re-enclavation the intraocular lens dislocated again. To avoid further dislocation, both superior fingers of the haptics were pushed through the iris tissue to achieve more stable support of the haptic ends. This method of fixation appeared to be well tolerated.

Abstract
Purpose To characterize the influence of decentration on higher-order aberrations of Artisan aphakic intraocular lens implantation eyes. Setting. Department of Ophthalmology and Vision Science, Eye and ENT Hospital of Fudan University, Shanghai, China. Design Retrospective case series. Methods Twenty-three eyes of 18 patients were retrospectively examined. Location of the IOL was imaged using a slit-lamp, and decentration (the distance from the center of a pupil to the geometric center of the IOL) was measured using the AutoCAD 2007 software. Ocular and internal higher-order aberrations were measured using the wavefront analyzer KR-1W (Topcon) and their correlation with decentration were analyzed. Coma, spherical, 3rd-, 4th-order, trefoil, tetrafoil aberrations, ocular, and internal higher-order aberrations were calculated for a 4.0 mm pupil diameter. Results The mean age of patients was 33.6 ± 21.4 years (ranging from 7 to 72 years). The mean follow-up period was 28.2 ± 10.5 months (ranging from 12 to 52 months). The mean postoperative best-corrected visual acuity (BCVA) was 0.19 ± 0.19 logMAR (range −0.18–0.52). The mean decentration was 0.57 ± 0.28 mm (range 0.15–1.21 mm). There was no correlation between Artisan IOL decentration and ocular higher-order aberrations, internal higher-order aberrations, coma, spherical, 3rd-, 4th-order, trefoil, and tetrafoil aberrations, respectively. There was a positive correlation between Artisan IOL decentration and 2nd-astig aberrations when 2nd-astig aberrations were less than 0.1. Conclusions The position of Artisan IOLs showed slight decentration and the amounts of decentration were not large enough to influence higher-order aberrations.

Abstract
Scleral and iris fixation of intraocular lenses (IOL) are useful in the treatment of surgical or traumatic aphakia, luxation, and subluxation of IOL if the patient does not present appropriate capsular support. However, there is no consensus in the literature about which of these 2 methods is safer and better. The authors performed a literature review searching the main postoperative outcomes obtained with the use of each surgical method. Scleral and iris fixation of IOL are efficient in correction of the patients' visual acuity, even though each technique presents distinct complications which depend especially on the experience of the surgeon with the performed surgical method. It is important to understand that individuals submitted to scleral or iris fixation present previous preoperative complications in their eyes. Besides, both procedures are very complex, involving intense manipulation of the eye globe. The success rate of these surgical techniques is highly variable and has a close relation to the preoperative conditions of the patient's eye and the improvement of the surgeon's learning curve.
