Abstract
A woman in her 50s presented with suspected open globe injury (OGI) of the right eye after being hit with a high velocity piece of plastic. Visual acuity at the time of presentation was counting fingers in the affected eye. Slit lamp examination revealed a full thickness laceration of the cornea and a traumatic cataract. Primary corneal repair was performed and the patient was left aphakic after cataract removal. Secondary intraocular lens placement was deferred for 2 years, after which time a scleral-fixated intraocular lens was implanted using the Yamane technique. Postoperative visual acuity of 20/50 was achieved, with the vision limited by persistent diabetic macular oedema. Thus, this case of successful implantation of a secondary lens using the Yamane technique in a patient with prior corneal laceration and traumatic cataract highlights that the Yamane technique can result in visual improvement in patients with prior OGI.

[Secondary implantation of retropupillary fixated iris-claw intraocular lenses]. DIE OPHTHALMOLOGIE 2023; 120:184-190. [PMID: 36028580 DOI: 10.1007/s00347-022-01714-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/29/2022] [Accepted: 07/31/2022] [Indexed: 02/07/2023]
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.

Predictive Factors and Management of Macular Edema after Retropupillary Iris-Claw Intraocular Lens Implantation in Aphakia: National Multicenter Audit-Report 2. J Clin Med 2023; 12:jcm12020436. [PMID: 36675364 PMCID: PMC9862359 DOI: 10.3390/jcm12020436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/16/2022] [Accepted: 12/31/2022] [Indexed: 01/06/2023] Open
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 describe the facilitated trailing haptic externalization technique for intrascleral intraocular lens (IOL) fixation. METHODS In this technique, first the direction of the 4-5 mm tip of the trailing haptic is straightened with the help of forceps. After the second needle enters the posterior chamber, the edge of the IOL optic is pushed towards the opposite scleral tunnel with the needle. The trailing haptic approaching the center from the periphery and the straightened distal part of the haptic towards the direction of the needle facilitate the relatively easily and gently placing of the haptic into the lumen with a one-time use of forceps. RESULTS This technique was performed on 65 eyes of 58 patients, with a mean patient age of 53.0 ± 14.6 years (range, 22-78). No complications such as endothelial touch, vitreous loss, iris or ciliary body damage, and hyphema were encountered during surgery. The mean operation duration was 14.8 ± 2.3 min (range, 12-20). In the postoperative period, there was only mild postoperative anterior chamber reaction in all eyes. Postoperative transient intraocular pressure (IOP) elevation that responded well to topical antiglucomatous therapy was observed in only two cases (3%). No patient developed haptic exposure, IOL dislocation, iris capture, postoperative hypotony, vitreous hemorrhage, choroidal effusion, cystoid macular edema, or retinal detachment. CONCLUSION The facilitated trailing haptic externalization technique provides a safer, simpler, and minimally invasive surgery without significant complications while easing the surgical difficulties of the Yamane technique.

J Curr Ophthalmol 2022; 34:277-283. [PMID: 36644474 PMCID: PMC9832467 DOI: 10.4103/joco.joco_62_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 05/02/2022] [Accepted: 05/03/2022] [Indexed: 12/12/2022] Open
Abstract
Purpose To assess the incidence of glaucoma after combined Descemet's stripping endothelial keratoplasty (DSEK) and retropupillary fixated iris-claw intraocular lens (IOL) implantation in the patients with bullous keratopathy (BK) who required secondary IOL or IOL exchange. Methods In this retrospective case series, medical records of 22 patients who underwent combined DSEK and retropupillary fixated iris-claw IOL implantation were evaluated. Preoperative vision, intraocular pressure (IOP), postoperative IOP at different time periods, and intraoperative and postoperative complications were analyzed. Results A total of 22 eyes of 22 patients (7 females and 15 males) were analyzed. The median age was 62 years, and the median duration of the postoperative follow-up was 106.5 days. The corrected distance visual acuity improved from a median of 1.85 logMAR to 1.68 logMAR. None of the patients had intraoperative complications. Three patients (13.6%) had dislocation of the donor tissue on the 1st postoperative day and were successfully rebubbled. Six eyes (27.3%) had graft failure and required penetrating keratoplasty. Eleven eyes (50%) had a sustained rise in the IOP, of which 2 (9.09%) had ocular hypertension and 9 eyes (40.9%) progressed to glaucoma. Conclusions DSEK combined with retropupillary fixated iris-claw lens is a good surgical option for the management of aphakic/pseudophakic BK in patients who require secondary IOL or IOL exchange. Regular IOP monitoring after the surgery is an essential, as there is a risk of IOP rise and glaucoma in the postoperative period. Clinicians should be vigilant and control the IOP to prevent glaucoma progression.

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
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.

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
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.
