Comparative long-term outcomes of vitrectomy combined with anterior chamber intraocular lens to intra-scleral haptic fixation of posterior chamber intraocular lens. Int J Retina Vitreous 2024; 10:59. [PMID: 39187860 PMCID: PMC11346030 DOI: 10.1186/s40942-024-00572-2] [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: 04/08/2024] [Accepted: 08/12/2024] [Indexed: 08/28/2024] Open
Abstract
PURPOSE To evaluate the long-term clinical outcomes in patients with combined pars plana vitrectomy (PPV) with anterior chamber intraocular lens (ACIOL) to intrascleral haptic fixation (ISHF) using the Agarwal technique with fibrin glue to secure the scleral flap of a posterior chamber intraocular lens. METHODS Retrospective, consecutive, single-center, comparative case series. 83 eyes were studied. Patients with < 8 months of follow-up were excluded. Detailed pre-, intra-, and post-operative complications were analyzed using mixed model univariate analysis and t-test. Pre- and post-operative best corrected visual acuity (BCVA) was analyzed. RESULTS Twenty-five subjects met entry criteria. Mean age at time of surgery was 70.4 ± 17.7 years in the ACIOL group (n = 12) and 54.6 ± 21.1 years in the ISHF group (n = 13; p = 0.03). Mean follow-up was 38.2 months. Incidence of corneal decompensation was similar in the ACIOL and ISHF lens group (p = 0.93). There was no difference in the BCVA mean change or cystoid macular edema (CME) at the final visit between the groups (p = 0.47; p = 0.08), but there was a trend toward increased CME in the ACIOL group. CONCLUSIONS PPV with concomitant placement of either ACIOL or ISHF lens result in improvement in BCVA. Both procedures are well tolerated and result in favorable outcomes with long-term follow-up though varying patient populations do not allow precise comparison between the two groups.

Abstract
Lens drop and intraocular lens (IOL) drop can occur after cataract or phacoemulsification surgery, where the IOL is dislocated from the capsular bag into the vitreous cavity. The aim of this study was to investigate the short-term outcomes of implanting a retropupillary iris-claw in patients with IOL drop and lens drop after phacoemulsification. A cross-sectional study was conducted at Santosa Hospital, Bandung, West Java, Indonesia, from January 2020 to December 2023. Patients were divided into two groups: IOL drop and lens drop groups. Total sampling was used, involving 51 patients in the present study, with 27 patients in the IOL drop group and 24 patients in the lens drop group. Data collected included age, sex, eye laterality, the onset of IOL drop or lens drop, intraocular pressure (IOP), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), record of astigmatism change preoperative and postoperative, and postoperative pars plana vitrectomy (PPV) complications. Our data indicated that the UDVA significantly improved in both IOL drop and lens drop groups after PPV surgery (p<0.001). However, there were no significant changes in IOP or astigmatism following the surgery in either group. Over one month, both groups showed improved UDVA, decreased IOP, and changes in astigmatism, with no significant differences between groups. Similarly, there was no significant difference in CDVA between IOL drop and lens drop groups. Only four complications were recorded in the present study. Comparing IOL drop and lens drop groups, only an increase in IOP showed a significant difference (p=0.018). Corneal edema, IOL decentration, and pupil ovalization were not significantly different. In conclusion, retropupillary iris-claw IOL implantation is safe and effective for aphakic patients with complications from phacoemulsification, regardless of whether it is lens drop or IOL drop.

Abstract
PURPOSE Evaluate long-term outcomes following Cionni modified capsule tension ring (MCTR) and in-the-bag intraocular lens (IOL) implantation in subluxated lenses. DESIGN Retrospective case series. METHODS Forty-one eyes of 31 patients from Raghudeep Eye Hospital, India, with subluxated lenses who had completed a minimum of 5 years' postoperative follow-up were included. Lens extraction, capsular bag fixation with MCTR using 9-0 polypropylene suture, and in-the-bag IOL implantation were performed in all eyes. Corrected distance visual acuity (CDVA), IOL centration, posterior capsule opacification, glaucoma, and retinal complications were documented at final follow-up. RESULTS The mean age of the cohort was 20.48 ± 16.46 (SD) years. Twenty-four eyes (58%) were below 15 years of age at the time of surgery. Marfan syndrome accounted for 37% cases. Mean follow-up was 9.89 ± 3.81 (SD) years. Thirty-two eyes (74%) had a CDVA of ≥0.3 logMAR at final follow-up. IOL decentration was noted in 7 eyes (17%), requiring a secondary surgery. The mean duration from primary surgery to resurgery was 8.79 years. Seventeen eyes (41%) required a laser capsulotomy, 88% of which were pediatric eyes. Retinal detachment occurred in 4 eyes (10%), 3 of which had Marfan syndrome. CONCLUSION Capsular bag fixation with an MCTR using 9-0 polypropylene and in-the-bag IOL implantation had good long-term visual outcomes with an acceptable rate of serious postoperative complications in eyes with subluxated lenses. This approach allows preservation of the natural compartments of the eye and placement of an IOL in its most physiological position. However, considering a 17% rate of IOL decentration requiring surgical intervention, long-term stability with nonbiodegradable suture materials such as polytetrafluoroethylene as well as decentration rates following sutured or sutureless scleral fixation should be compared.

Abstract
This retrospective study aimed to compare the outcomes of modified double-flanged sutureless scleral fixation versus sutured scleral fixation. Medical records of 65 eyes from 65 patients who underwent double-flanged scleral fixation (flange group) or conventional scleral fixation (suture group) between 2021 and 2022 were reviewed. Visual and refractive outcomes, as well as postoperative complications, were compared 1, 2, and 6 months after surgery. We included 31 eyes in the flange group and 34 eyes in the suture group. At 6 months postoperatively, the flange group showed better uncorrected visual acuity (0.251 ± 0.328 vs. 0.418 ± 0.339 logMAR, P = 0.041) and a smaller myopic shift (- 0.74 ± 0.93 vs. - 1.33 ± 1.15 diopter, P = 0.007) compared to the suture group. The flange group did not experience any instances of iris capture, while the suture group had iris capture in 10 eyes (29.4%; P < 0.001). In the flange group, all intraocular lenses remained centered, whereas in the suture group, they were decentered in 8 eyes (23.5%; P = 0.005). The double-flanged technique not only prevented iris capture and decentration of the intraocular lens but also reduced myopic shift by enhancing the stability of the intraocular lens.

Abstract
PURPOSE To describe the innovative technique of trocar-assisted intraocular lens (IOL) and capsular bag complex fixation. METHODS In this technique, initial pupil dilatation is achieved either with intracameral adrenaline or with the help of iris hooks. Automated anterior vitrectomy is performed in cases with vitreous prolapse. A 25 G trocar cannula is placed at the limbus through a paracentesis opposite the zonular dialysis area. The cannula lumen act as a guide to pass the double-arm polypropylene suture attached to the needle. This prevents any inadvertent corneal injury and acts as a perpendicular tract to pass the needle through IOL capsular bag complex. RESULTS We performed this technique in 9 cases with an excellent outcome with a minimum of 3 months of follow-up. All patients had well-centred IOL. There was no incidence of corneal injury, Descemet membrane detachment, iris trauma, IOL tilt, decentration, dislocation, vitreous prolapse or retinal detachment. All patients achieved excellent visual acuity ranging from 6/12-6/6 postoperatively. CONCLUSION The novel trocar-assisted IOL bag complex fixation technique is very effective and allows smooth IOL fixation in technically challenging cases with IOL subluxation. The trocar acts as a guide to prevent injury to the surrounding tissue, and IOL fixation is achieved with minimal manipulations in the anterior chamber. It also prevents the need for IOL explantation in these cases.

Abstract
Congenital subluxation of the lens as a complication of Marfan syndrome, Weill-Marchesani syndrome, microspherophakia, etc. leads to the development of amblyopia and requires timely surgical treatment with removal of the subluxated lens and implantation of an artificial intraocular lens (IOL). IOL implantation in children with pathology of the ligamentous apparatus of the lens remains an urgent problem of ophthalmic surgery due to the lack of a consensus regarding the IOL fixation method among practitioners. PURPOSE This study evaluated the effectiveness and safety of IOL implantation with transscleral fixation using the knotless Z-suture technique in pediatric patients with congenital lens subluxation. MATERIAL AND METHODS The study included 24 children (36 eyes) with grade III congenital subluxation of the lens who underwent phacoaspiration of the subluxated lens with IOL implantation with transscleral fixation using the knotless Z-suture performed in the Kazakh Research Institute of Eye Diseases in Almaty in the period from 2017 to 2021. The average observation period was 31.7±11.3 months (2.0 to 4.5 years). The stability of the IOL position, the state of the intrascleral sutures, visual acuity after surgery, the presence and severity of complications in the long-term period were evaluated. RESULTS All patients (100%) had a significant improvement in visual acuity after surgery. No intraoperative complications were registered in any of the cases. Postoperative complications were noted in 8.3% of cases (n=3). The final functional outcome of surgical treatment depended on the presence of concomitant pathology, the main cause of low vision was the development of refractive amblyopia due to refractive errors. CONCLUSIONS The presented technique of transscleral fixation of IOL has proven to be reliable, which is especially important for pediatric patients considering their high physical activity and expected lifespan.

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.

Abstract
OBJECTIVE To identify changes in secondary lens techniques over time and to determine common complications of each technique. DESIGN Retrospective cohort study. PARTICIPANTS All patients in the database from January 2015 to December 2021 who underwent secondary lens placement (anterior chamber intraocular lens [IOL, ACIOL], scleral-fixated IOL [SFIOL], or scleral-sutured IOL [SSIOL]). METHODS Rates of secondary IOL surgery techniques were analyzed in 3597 participants in a nationwide aggregated electronic health care database using 2-sample independent t tests. Rates of postoperative rhegmatogenous retinal detachment (RRD) after secondary IOL surgery were assessed using chi-square test of proportion. Postoperative visual acuity (VA) was assessed using 2-sample independent t tests. MAIN OUTCOME MEASURES The primary outcome was change in IOL technique over time. Secondary data points examined were the development of postoperative RRD after secondary IOL surgery, VA changes, the development of endophthalmitis, suture erosion, haptic erosion, or corneal edema after IOL surgery. RESULTS Anterior chamber IOL use decreased over the 7-year period from 93% of cases to 36% of cases (P < 0.0001), while SFIOL use increased from 3% to 34% (P < 0.0001) and SSIOL use increased from 4% to 30% (P < 0.0001). Visual acuity increased for each surgical technique (ACIOL: 44.1 vs. 49.2 ETDRS letters, P < 0.001; SFIOL: 48.7 vs. 57.6 letters, P < 0.001; SSIOL: 51.5 vs. 61.2 letters, P < 0.001), with larger VA gains seen in SFIOL and SSIOL use (ACIOL vs. SFIOL, P = 0.004; ACIOL vs. SSIOL, P = 0.002; SFIOL vs. SSIOL, P = 0.64). Average RRD rates did not significantly differ between techniques. Rates of endophthalmitis, haptic erosion, and suture erosion were low and did not significantly differ between techniques. Rates of corneal edema were significantly higher in ACIOL cases (vs. SFIOL, P < 0.0001; vs. SSIOL, P < 0.0001). CONCLUSIONS Rates of ACIOL implantation performed by vitreoretinal surgeons have decreased over time with more vitreoretinal surgeons electing to place either an SFIOL or SSIOL toward the end of the study period; complication profiles among the 3 techniques may be similar.

Abstract
AIM To identify the current surgical management of aphakia and the outcomes and complications of each technique. METHODS This cross-sectional study included ophthalmic surgeons with at least one-year experience in surgery for aphakia. A study questionnaire was formulated to collect data in Saudi Arabia and other regional countries. The questionnaire included 22 questions on demographics, preferred surgical techniques, complications and the factors related to surgeon decision and the choice for managing aphakia. RESULTS The study included 145 participants (111; 76.6% were males) with mean age of 46.7 ± 11.5 years. The mean duration of cataract surgery experience was 17.6 ± 11.1 years. Most participants (86.2%) were trained in cataract surgery. Scleral fixation of intraocular lens (SFIOL) was the most commonly preferred technique, followed by iris fixation IOL, and anterior chamber IOL (75.2%, 9%, and 15.9%, respectively). The main determinants for selection of a surgical technique were simplicity (56.6%), surgical instrument availability (48.3%), and training on the technique (47.6%). The most frequent postoperative complications were pupil distortion, high intraocular pressure (IOP), pupillary capture of the IOL, and IOL decentration. CONCLUSIONS SFIOL is the preferred surgical technique for managing aphakia. The decision to choose one technique over another is complex and is based on several factors, including technical difficulty, previous training, anatomical variations, ocular comorbidities, and the potential complications. The most frequent complications after surgical correction of aphakia are pupil distortion, high IOP, pupillary capture of the IOL, and decentered IOLs.

Abstract
INTRODUCTION The aim of this study was to evaluate the outcome of the modified Carlevale intraocular lens (IOL) fixation technique, using two different vitrectomy ports (23- vs. 27-gauge) as anchor fixation. METHODS Retrospective, consecutive study of 282 eyes (282 patients) who underwent a secondary IOL implantation using the Carlevale IOL (Soleko IOL Division, Italy) with two anchor haptics for intrascleral implantation with either 23- or 27-gauge (G) port. RESULTS Transient post-operative ocular hypotonia (intraocular pressure ≤5 mm Hg) was observed less in the 27-G group (13 vs. 4 patients, p = 0.057) three requiring additional tunnel sutures (2 cases for 23-G; 1 case 27-G). Post-operative vitreous haemorrhage was recorded more often in the 23-G group (8 vs. 1 patient, p = 0.034), but all cases in both groups resolved without intervention. Visual acuity did improve post-operatively in the two groups. No post-operative complications such as retinal detachment, endophthalmitis, and IOL-dislocation tilt were observed in the follow-up. CONCLUSION The 27-G modified technique for sutureless intrascleral implantation is simple and effective and causes less post-operative hypotony.

Wang T, Chen Y, Lu J, Li N, Min H. A novel surgical approach for fixation of a posterior chamber intraocular lens of Rayner 620 H with Gore-Tex suture. BMC Ophthalmol 2023; 23:20. [PMID: 36635644 PMCID: PMC9835369 DOI: 10.1186/s12886-022-02759-3] [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: 07/20/2022] [Accepted: 12/26/2022] [Indexed: 01/13/2023] Open
Abstract
PURPOSE To report a novel surgical approach for the scleral fixation of the Rayner 620 H intraocular lens (IOL) with Gore-Tex suture and its outcomes at 6 months postoperatively. METHODS 19 consecutive patients who underwent novel surgical approach for the scleral fixation of Rayner 620 H IOL with Gore-Tex suture at Peking Union Medical College Hospital between June 2020 and June 2021 were included. Data on best-corrected visual acuity (BCVA), spherical equivalent, total astigmatism/axis, short-term and long-term complications, and corresponding management with a follow-up of 6 months were collected. RESULTS Nineteen patients (11 men and 8 women) with a mean age of 62.7 ± 10.6 years were included. The median BCVA improved significantly from 0.90 ± 0.90 (Snellen 20/160) preoperatively to 0.20 ± 0.30 (Snellen 20/32) at postoperative 6 months follow-up (P < 0.001). The stratification of the accuracy of refractive outcomes was 53% of patients within ± 0.5 D and 84% of patients within ± 1.0 D of the refractive target. Corneal edema (n = 3, 16%) and increased intraocular pressure (IOP) (n = 4, 11%) were short-term complications. Long-term complications included increased IOP (n = 1, 5%), and macular edema (n = 1, 5%). CONCLUSION The novel surgical approach for scleral fixation of the Rayner 620 H IOL with Gore-Tex suture is a reasonable option for patients who need secondary IOL placement without adequate capsular support.

Abstract
PURPOSE The purpose of this study was to report a rare case of cyclodialysis cleft after secondary intraocular lens (IOL) placement using the Yamane flanged intrascleral haptic fixation technique. METHODS This study is an observational case report. RESULTS A 74-year-old man with an ocular history of spontaneously dislocated IOL and subsequent anterior chamber IOL (ACIOL) placement presented with monocular diplopia secondary to ACIOL subluxation. The patient underwent explantation of the subluxed ACIOL and placement of a scleral-fixated IOL using the Yamane technique. The postoperative course was complicated by persistent hypotony, prompting ultrasound biomicroscopy, which revealed a cyclodialysis cleft adjacent to one of the externalized IOL haptics. The haptic was discovered in the involved supraciliary space while performing direct cyclopexy. The cyclodialysis cleft closed with return to physiologic intraocular pressure. CONCLUSIONS Cyclodialysis cleft formation is a possible complication of scleral IOL fixation and should be suspected in cases of prolonged postoperative hypotony. Extended longitudinal tracking of the needle and haptic through the supraciliary space may be one mechanism for cyclodialysis cleft formation in the Yamane technique.

Abstract
Purpose Scleral-fixation of intraocular lenses (IOLs) provides an option for eyes that lack sufficient capsular support for in-the-bag IOL placement. The latest techniques for lens fixation include use of a novel suture material, Gore-Tex, and a sutureless method, with flanged intrascleral fixation. The purpose of this pilot study was to compare these methods in terms of anatomic and clinical outcomes. Methods A total of 35 eyes of patients 18-60 years of age who presented with aphakia, subluxated lens, or ectopia lentis were randomized into two groups. Group A (15 eyes) underwent flanged intrascleral IOL fixation using the Yamane technique; group B (20 eyes) underwent 4-point transscleral fixation of IOL using Gore-Tex suture. The following parameters were compared between groups on day 1, week 3, and month 6 postoperatively: logMAR uncorrected and best-corrected visual acuity, retinoscopy, IOL centration on slit-lamp biomicroscopy, and IOL tilt on ultrasound biomicroscopy. Results Postoperative visual acuity was better in group B: uncorrected, logMAR 0.89 ± 0.22 versus 0.72 ± 0.24 (P = 0.046); best-corrected, logMAR 0.51 ± 0.18 versus 0.37 ± 0.26 (P = 0.016). No significant difference was found in postoperative retinoscopy and astigmatism between groups. IOL tilt (>100 µm) occurred in 8 cases in group A and in 9 cases in group B; 87% in group A and 100% in group B were well centered. Complications in both groups were minimal. Conclusions In our small study cohort, both sutureless flanged IOL fixation and Gore-Tex sutured scleral IOL fixation resulted in excellent visual rehabilitation of patients with aphakia and subluxated lenses. Patients who underwent Gore-Tex suture fixation experienced better postoperative visual acuity, IOL centration, and stability.

Abstract
In the absence of capsular support, it is not always possible to safely place an intraocular lens (IOL) in the capsular bag at the time of surgery. Several techniques have thus been developed to enable safe placement of a secondary IOL outside the capsular bag. These techniques include placement of anterior chamber IOLs, iris-fixated IOLs (sutured, iris-claw), and scleral-fixated IOLs (sutured, sutureless). Secondary IOL placement can take place at the time of the initial surgery or in a second surgery. Each technique has its own unique advantages, as well as its potential complications. At this time, comparison studies have found no secondary IOL technique to be superior in terms of visual acuity or rate of complications. Additional comparison studies with longer follow-up times are needed to confirm these findings. The decision on which secondary IOL technique to perform depends on numerous factors including surgeon experience and comfort, as well as patient comorbidities.

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
UNLABELLED For the moment, the refractive outcomes of out-of-the-bag intraocular lens (IOL) implantation remain insufficiently studied. PURPOSE To study and compare the refractive outcomes of retropupillary implantation of an iris-claw lens and transscleral suture fixation of IOL in complicated phacoemulsification. MATERIAL AND METHODS The study included 70 patients (73 eyes) after complicated phacoemulsification in combination with grade 2 lens subluxation. The first group included 36 patients (39 eyes) who underwent complicated phacoemulsification using torsional ultrasound and retropupillary implantation of an iris-claw lens. The second group included 34 patients (34 eyes) after complicated phacoemulsification using torsional ultrasound and transscleral suture fixation of an elastic hydrophobic IOL. In the postoperative period we performed a comparative evaluation of uncorrected visual acuity and best corrected visual acuity, the average absolute error of IOL optical power calculation, the precision of postoperative refraction within ±0.5 diopters, the degree of induced astigmatism, and the tilt of the IOL. RESULTS At three months after surgery uncorrected visual acuity of 0.8-1.0 was achieved in 33.3% of cases in the first group and 17.6% in the second group, the average absolute error of IOL optical power calculation was 0.34±0.08 diopters in the first group and 0.63±0.19 diopters in the second group, the precision of postoperative refraction within ±0.5 diopters was 94.9% in the first group and 85.3% in the second group, the tilt of the IOL was 0.69±0.21° in the first group and 3.19±0.97° in the second group (p<0.05). There were no significant differences in best corrected visual acuity and the degree of induced astigmatism 3 months after surgery. CONCLUSION Implantation of an iris-claw lens in the course of complicated phacoemulsification in lens subluxation significantly improves refractive outcomes of the implantation in comparison with transscleral IOL fixation.

Abstract
To report a case of bilateral pseudophakic bullous keratopathy (PBK) in a patient having bilateral microcornea with pre-existing anterior chamber intraocular lens (ACIOL) who underwent Descemet stripping endothelial keratoplasty (DSEK) with a successful postoperative visual outcome. A 36-year-old female, diagnosed with microcornea and congenital cataract in both eyes underwent lens aspiration sequentially followed by ACIOL implantation in both eyes. The patient reported to our centre and was diagnosed with bilateral PBK with ACIOL with microcornea. She also had associated secondary glaucoma, postoperative chronic uveitis, and hyphaema, which were controlled with medical management first and taken into consideration while planning DSEK. The patient underwent manual DSEK without intraocular lens exchange under local anaesthesia in both eyes sequentially with a good visual recovery postoperatively in both eyes. Descemet stripping automated endothelial keratoplasty (DSAEK)/DSEK seems a viable option in patients with microcornea who develop PBK following cataract surgery with retained ACIOL where there is absence of capsular support as well as deficiency of iris tissue.

Abstract
Varied options are available for the implantation of secondary intraocular lens implants in the absence of zonular or capsular support. Loss of the capsule can occur in the context of complicated cataract surgery, trauma or inherited conditions such as Marfan syndrome or pseudoexfoliation. Approaches to overcome this include optical measures such as the use of spectacles or contact lenses, and surgical therapy incorporating the use of anterior chamber, iris-fixated or scleral-fixated lenses. Surgical techniques to implant scleral-fixated lenses have undergone various modifications, since the first publication of sutured intrascleral fixation described in the 1980s. However, despite the advances in surgical techniques, studies are limited either by their retrospective nature, small sample size and most importantly small duration of follow-up. This comprehensive review aims to amalgamate the evolution of various surgical techniques with regards to intrascleral lens fixation and suggests areas for future development.

Abstract
Importance/Background To describe the characteristics and 1-year postoperative surgical outcomes of primary combined trans pars plana vitrectomy (TPPV) with iris-fixated posterior-chamber intraocular lens (IF-PCIOL) implantation for subluxated cataracts and intraocular lenses (IOLs). Methods Consecutive cases of significantly subluxated cataracts and IOLs from January 2014 to May 2019 were included in this retrospective case series. Results A total of 103 eyes of 103 patients were included. Median age was 67.4 (interquartile range [IQR] 27–89) years. Thirty-two (31.1%) had subluxated cataracts, while 71 (68.9%) had subluxated IOLs. Overall median preoperative logMAR BCVA was 0.9 (IQR 0–2.5). Median logMAR BCVA improved to 0.3 (0–1.9) and 0.2 (0–1.8) for the subluxated cataract and IOL groups, 81.2% and 75% of eyes achieved logMAR ≤ 0.3, and 94% and 97% achieved IOL stability at month 12, respectively. Eyes with subluxated IOLs had a significantly less myopic median SE if a new IOL was implanted compared to iris-fixating the dislocated IOL. Conclusion Combined primary TPPV and IF-PCIOL implantation is a good surgical option for subluxated IOL or cataract without sufficient capsular support, with at least 75% achieving logMAR BCVA ≤ 0.3 and 95% IOL stability at postoperative year 1. In eyes with subluxated IOLs, explanting that IOL and iris-fixating a new IOL led to a reduced SE and better visual outcome at postoperative month 12 when compared to iris-fixating the dislocated IOL.

Abstract
PURPOSE To report intraoperative performance and long-term postoperative outcomes after scleral fixation of intraocular lenses (IOLs) with polytetrafluoroethylene suture (PTFE). SETTING Raghudeep Eye Hospital, Ahmedabad, India. DESIGN Prospective, interventional case series. METHODS One hundred eyes undergoing scleral fixation of IOLs using PTFE suture (Gore-Tex) with 12 months or more postoperative follow-up were included. The primary outcome measures were occurrence of intraoperative and postoperative complications such as glaucoma, suture-related complications, and inflammation within the follow-up period. The secondary outcome measure was improvement in visual acuity (VA). RESULTS Of the 100 eyes, posteriorly dislocated IOLs (53 eyes) followed by dropped nuclei (33 eyes) were the most common surgical indications. Mean follow-up was 23 months (range 12 months to 5 years). Seventy-one patients (77.17%) had 18 months or more follow-up; 21 eyes had a rise in intraocular pressure in the early postoperative period; 12 of them required glaucoma surgery. Early complications were vitreous hemorrhage in 13 eyes, retinal detachment in 6 eyes, and transient hyphema in 1 eye. Late postoperative complications were cystoid macular edema (9 eyes), epiretinal membrane (3 eyes), and bullous keratopathy (3 eyes). Mean VA improved from 0.92 ± 0.16 (SD) logarithm of the minimum angle of resolution (logMAR) preoperatively to 0.41 ± 0.27 logMAR. LogMAR at final follow-up was 0.41 ± 0.28 (P < .01). There were no cases of suture-related complications (erosion/breakage/granuloma) or IOL decentration throughout the follow-up period. CONCLUSIONS Scleral fixation of IOLs with PTFE suture was found to be safe and well tolerated. All eyes had well-centered IOLs, with no suture-related complications during long-term follow-up. VA improved significantly with acceptable postoperative complications.

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
The authors describe the surgical techniques to implant a novel intraocular lens with artificial iris (Reper) in patients affected by traumatic aphakia and aniridia. Two surgical approaches are proposed: implantation by suture-loaded cartridge and "open sky" implantation combined with penetrating keratoplasty. The method of establishing the exact position of the scleral fixation points and the pre-assembly of the suture of Reper before its implantation are the main novel proposed surgical procedures. The rationale is to minimize surgical procedures in the anterior chamber and to prevent knot loosening and lens tilting. The simultaneous treatment of aphakia and aniridia with a single prosthesis, the stability of the Reper and the functional, anatomical and aesthetic outcomes obtained are the highlighted advantages in this study.

Abstract
Purpose To assess the role of surgical peripheral iridectomy (PI) in preventing iris-related complications associated with glued intraocular lens (GIOL) surgery in children with bilateral ectopia lentis. Methods Nonrandomized interventional case series of 34 eyes of 17 children (<15 years of age) who underwent pars plana lensectomy (PPL) and GIOL surgery between January 2013 and December 2016. Eyes with surgical PI (January 2013-June 2015) were compared with those without surgical PI (July 2015-December 2016). The primary outcome measure of the role of surgical PI in GIOL surgery was to account for complications such as optic capture, secondary glaucoma, intraocular lens (IOL) dislocation, or repeat surgery. The secondary outcomes were changes in the best-corrected visual acuity (BCVA). Results The mean age at surgery was 8.8 years (range: 3.5-15 years). Surgical PI was conducted in 15 eyes. Among the 19 eyes without PI, 9 eyes had complications (optic capture -6; rise in IOP -4; IOL subluxation -4; repeat surgery -5). The complications were significantly less in the PI group, P = 0.02. There was a statistically significant improvement in BCVA (P = 0.0001) in all the patients. The mean presenting BCVA was 0.99 (±0.79) logMAR (Snellen ≈ 20/200) and post BCVA was 0.40 (±0.50) (Snellen ≈ 20/50). The mean preoperative refraction was - 9 D (±8D) (range: -5 D to -23D) and postoperative was -1 (±1.15) D. The mean follow-up was 25.4 months. Conclusion Surgical PI along with GIOL surgery in children undergoing PPL is shown to reduce optic-capture-related complications.

Abstract
BACKGROUND Scleral fixation of intraocular lenses has become a popular procedure for treating aphakia in the absence of capsular support. However, the lens formulas used to predict refractive outcomes were designed for in-the-bag lens placement. This study evaluates the accuracy of the SRK/T formula in predicting a target postoperative refraction when suturing a scleral-fixated intraocular lens (IOL) implant 3 mm posterior to the limbus. METHODS This is a retrospective, case series including 20 eyes of 20 patients who underwent scleral fixation of Akreos AO60 IOLs (Bausch & Lomb, Rochester, NY) by a single surgeon at the OSU Wexner Medical Center. Preoperative measurements were performed with optical biometry, and IOL power was calculated with the SRK/T formula. Following surgery, the actual refractive spherical equivalent (SE) was performed and compared with the preoperative prediction. Prediction error (PE), defined as the deviation of actual postoperative SE refraction in diopters (D) from preoperative predicted SE refraction, was the primary outcome measure. RESULTS The mean attempted (predicted) SE was - 1.12 D (± 0.87). Mean achieved SE was - 0.96 D (± 1.04). Mean PE (actual postoperative SE versus predicted preoperative SE) was 0.16 D (± 0.69). A total of 9 eyes (45%) were within ± 0.5 D of the predicted SE, 16 eyes (80%) were within ± 1.0 D, and all 20 eyes (100%) were within ± 1.5 D. CONCLUSION IOL power calculation using the SRK/T formula with optical biometry demonstrates reliable postoperative refractive outcomes in patients undergoing scleral fixation of an IOL (Akreos AO60). Further studies are needed to refine the predictive value of the SRK/T and other formulas for application in scleral fixation of IOLs.

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
We designed this study to assess if surgical safety can be improved by intraoperative use of intraocular lens (IOL) for cataract phacoemulsification. We performed phacoemulsification cataract removal on 401 patients. We randomly assigned these patients into three groups: the standard setting (Group I, n = 134), with reduced vacuum and flow rate (Group II, n = 137), and with IOL insertion before the last quadrant was emulsified with standard setting (Group III, n = 130). The primary outcomes included the risk of posterior capsular rupture (PCR), ultrasound time, energy, and complications. The secondary outcomes included central corneal thickness (CCT), CCT changes, endothelial cells (ETC) counting, ETC loss, and the best corrected distance visual acuity (BCVA) measured on day 1, day 7 and day 30. If PCR occurred, we emulsified the residual lens materials after insertion of IOL and clean of the prolapsed vitreous. We found that the risk of PCR in Group III (0/130) was lower than Group I (9/134, corrected relative risk (RR) = 18.44, 95% CI: 1.08–313.56) and Group II (3/137, corrected RR = 6.64, 95% CI: 0.35–27.41). Group III showed better BCVA on day 1 and 7, less ECC loss on day 7 and 30, and less CCT increase on day 1 and 7. No cases converted to extracapsular cataract extraction. No residual lens materials misdirected into vitreous cavity. Intraoperative use of IOL can improve surgical safety for dense cataract phacoemulsification.

Abstract
Luxation of intraocular lens in capsular bag several years after cataract surgery leads to a decrease in visual function and requires surgical treatment.Aim: to determine effectiveness of various types of surgical treatment of late spontaneous dislocations of IOL in capsular bag.Methods. Analysis of 123 case histories of patients with late IOL dislocation, operated in 2013–2015, was made. First group included patients with replaced IOLs dislocated into pupillary lens. Second group consisted of patients who underwent reposition and suture of IOL to iris. Examination was made before operation and 6–12 months after operation. Results. The average term from moment of IOL implantation to its luxation was 8.78 ± 4.85 years. II degree of dislocation was detected in 74 % of patients, III degree of dislocation – in 10 %, and IV degree – in 16 % of patients.Uncorrected visual acuity was reduced to 0.15 ± 0.16; best corrected visual acuity to 0.31 ± 0.26. In 83.7 % of patients a pseudoexfoliation syndrome was detected. In 62.6 % of patients IOL luxation was accompanied byhydrodynamic disturbances. Best corrected visual acuity in period from 6 to 12 months after surgery was 0.40 ± 0.24, and after IOL reposition – 0.49 ± 0.22. In addition, after IOL replacement a significant increase in postoperative astigmatism was noted from –0.44 ± 0.84 to –1.96 ± 1.60 D (p < 0.001).Conclusion. As a result of surgical treatment of late spontaneous IOL dislocations in both groups increase in distance uncorrected and best corrected visual acuity was noted. Insufficient visual functions after surgical treatment were caused by concomitant pathology as well as increased postoperative astigmatism.

Abstract
PURPOSE Purpose: To evaluate the long-term stability of scleral-sutured intraocular lenses (IOLs) and analyse the possible causes of suture breakage. SETTING Barraquer Institute in Barcelona, Spain. DESIGN Retrospective study of consecutive cases. METHODS Study of patients with scleral-sutured IOL with aphakia, subluxated or luxated IOL were included. Follow-up was longer than 6 months and patients over 18 years of age. Preoperative data (best-corrected visual acuity testing (BCVA), intraocular pressure (IOP), axial length and slit-lamp examination), intraoperative data (characteristics of the scleral flaps, suture material (Prolene or Mersilene) and scleral-sutured IOL) and postoperative data (BCVA, IOP, slit-lamp examination and complications) through 10 years were collected for analysis. RESULTS 345 consecutive cases of scleral-sutured IOL were included. 25 eyes underwent a second operation after a prior sutured IOL due to suture breakage (mean 40.2±39.6 months after the first surgery) and three of them needed a third surgery. Younger adults (less than 40-year old), the use of a combination of Prolene and Mersilene sutures to perform the surgery and suturing only one flap were found to have higher risk of suture breakage after a follow-up of 10 years. The probability of surviving of the scleral-sutured IOL at 10 years after surgery was 0.79. CONCLUSIONS Scleral-sutured posterior chamber IOL in eyes with a lack of capsular support is a safe and effective procedure with a low rate of complication and stable visual acuity. Further studies with special focus on young adults or myopic eyes are required to demonstrate long-term safety in those special cases.

Abstract
PURPOSE To examine the clinical outcomes of intraocular lens (IOL) scleral fixation with the friction knot technique. METHODS Retrospective case series of 152 eyes of 152 patients with inadequate capsular bag support operated with the friction knot IOL scleral fixation technique by a single surgeon. The fixated IOLs were one-piece or three-piece models all with open loop haptics. Main outcome measures were change in corrected distance visual acuity (CDVA) and postoperative complications. RESULTS The mean follow-up time was 11.7 months (median 4.9, range 0.7-64.8). The mean logarithm of the minimum angle of resolution CDVA improved from preoperative 0.77 ± 0.73 (Snellen 20/118 ± 7.3 lines) to 0.44 ± 0.56 (Snellen 20/55 ± 5.6 lines) at the final visit (p < 0.001). The main postoperative complications were ocular hypertension (30.3%), uveitis-glaucoma-hyphaema syndrome (12.5%; UGHS), vitreous haemorrhage (11.2%) and retinal detachment (8.6%). Two (1.3%) cases of suture breakage were seen. In multivariate Cox regression analysis, age under 60 years [hazard ratio (HR) = 5.41; 95% confidence interval (CI) 1.95-15.01] and scleral fixated one-piece IOL (HR = 4.23; 95% CI 1.44-12.44) were found as significant independent risk factors for developing new UGHS. CONCLUSION The friction knot technique provides a firm scleral fixation. Scleral fixation may successfully be utilized in dislocated three-piece IOLs with loop haptics. We recommend avoiding scleral fixation of one-piece IOLs in young patients due to a high risk of UGHS.

Abstract
PURPOSE To compare the clinical outcomes and main complications of transscleral-fixated (TSF), intrascleral-fixated (ISF), and iris-fixated (IF) intraocular lenses (IOLs). DESIGN Systematic review and network meta-analysis. METHODS The authors searched PubMed, EMBASE, and the Cochrane Library for relevant articles up to April 2017 with no language restrictions, and related studies meeting the eligibility criteria were included. A Bayesian framework was applied to compare the visual outcomes and complications of these 3 approaches. RESULTS A total of 14 studies with 845 eyes were included in the present report. There was no significant difference between any pair of surgical approaches in best-corrected visual acuity (BCVA) and in final BCVA achieving 20/40 or better (Snellen). ISF presented a lower risk of cystoid macular edema (CME) compared with TSF (risk ratio [RR], 0.45; 95% confidence interval [CI], [0.18, 1.0]). IF showed superiorities in less intraocular hemorrhage (IOH) than ISF (RR, 0.078; 95% CI [0.0095, 0.38]), as well as TSF (RR, 0.26; 95% CI, [0.09, 0.72]). IF had a lower risk of glaucoma escalation; the difference was slightly higher than the conventional level of significance (RR, 0.41; 95% CI, [0.16, 1.04]). Moreover, the surgical time in IF was shorter than TSF (standard mean difference [SMD], -2.98; 95% CI, [-4.32, -1.64]) and ISF (SMD, -2.60; 95% CI, [-3.71, -1.49]). However, IF was associated with a significantly higher risk of endothelial cell density (ECD) impairment (SMD, -0.54; 95% CI, [-1.02, -0.05]) and significantly greater postoperative corneal endothelial cell loss rate (ECLR, %) (SMD, 0.35; 95% CI, [0.08, 0.63]) compared with TSF. CONCLUSIONS Postoperative visual outcomes were comparable among TSF, ISF, and IF for eyes with insufficient capsular support. However, the risk of some complications differed among approaches. IF showed its superiorities in lower risk of IOH and glaucoma escalation as well as shorter surgical time, while IF was at a disadvantage in greater endothelial cell impairment. Since some patients might have a clear contraindication to one of the surgical approaches, the decision of surgical approach eventually depends on surgeon experience and the presenting pathology.

Abstract
PURPOSE To apply a previously published scleral fixation technique to secure one-piece acrylic intraocular lenses (IOLs) to the sclera. METHODS Retrospective, consecutive, noncomparative case series. RESULTS All patients (16 eyes of 15 patients) who underwent scleral fixation of 1-piece acrylic IOLs using the loop method from 2014 to 2016 were included. The mean follow-up was 8.1 months. Repositioning of dislocated 1-piece acrylic IOLs was performed in 8 eyes, a primary implantation in 5 eyes, and IOL exchange in 3 eyes. All IOLs remained well-centered postoperatively. The vision improved from an initial best-corrected visual acuity of 0.97 ± 0.74 logMAR (Snellen equivalent ≈20/190) to 0.47 ± 0.49 logMAR (≈20/60, P = 0.031) at the last follow-up. The postoperative complications were self-limited. CONCLUSION The previously reported scleral suture fixation technique can be readily applied to one-piece acrylic IOLs.

Abstract
Background To evaluate the safety and efficacy of combined 23-gauge transconjunctival pars plana vitrectomy and scleral fixation of intraocular lens (IOL) without conjunctival dissection. Methods A retrospective study in Chang Gung Memorial Hospital, Keelung and Taoyuan, Taiwan. Patients receiving combined 23-gauge transconjunctival pars plana vitrectomy and scleral fixation of IOL without conjunctival dissection were enrolled. The ocular findings, causes of lens complication, surgical procedures, type of IOL used, and complications were documented. Results We included 40 eyes from 39 patients (27 male, 12 female) with a mean age of 59.5 [standard deviation (±) 14.8] years old. The mean follow-up duration was 6.8 ± 5.4 months. The cause of lens complications was ocular trauma in 24 (60%) eyes, cataract surgery complications in 11 (28%) eyes, and spontaneous subluxation of crystalline lens in 5 (13%) eyes. The overall best corrected visual acuity (BCVA) (logMAR) improved from 1.359 ± 0.735 to 0.514 ± 0.582 (p < 0.001). The BCVA also improved significantly in each group with different causes of lens complications. Preoperative BCVA was the only factor associated with the postoperative visual outcome (p = 0.008). Most surgery-related complications were self-limited, including mild vitreous hemorrhage (5%), microhyphema (5%), transient elevated intraocular pressure (3%), and transient hypotony (3%). Cystoid macular edema and IOL decentration was found in 3 (8%) eyes and 1 (3%) eye respectively. Conclusions Combined 23-gauge transconjunctival vitrectomy and scleral fixation of IOL without conjunctival dissection is effective and safe in managing a wide variety of lens complications, with good postoperative comfort and visual recovery.

Abstract
PURPOSE: To describe the clinical outcomes of traumatic aphakic eyes with corneal astigmatism after using a novel technique for toric intraocular lens suture fixation. METHODS: In total, 12 eyes of 12 patients who underwent a new scleral suture fixation technique of one-piece toric intraocular lens (SN6AT series, Alcon Inc., TX, USA) were included in our retrospective study. Preoperative patient status, postoperative visual acuity and refractive outcomes, postoperative intraocular lens rotation, tilt, decentration, and complications were analyzed. RESULTS: The mean follow-up was 11.6 ± 1.0 months. The mean preoperative best-corrected visual acuity was 0.55 ± 0.32 in the logarithm of minimum angle of resolution equivalent; the postoperative best-corrected visual acuity was 0.45 ± 0.34. The mean preoperative total corneal astigmatism was 2.51 ± 1.67 D. The mean postoperative residual astigmatism was 0.77 ± 0.54 D. The mean intraocular lens rotation was 3.33° ± 1.37° (range, 1°-6°). The mean intraocular lens tilt in horizontal direction was 3.64° ± 1.02° (range, 2.6°-6.3°) and in vertical direction it was 3.19° ± 1.07 ° (range, 1.6°-5.2°). The mean intraocular lens decentration in horizontal direction was 0.14 ± 0.03 mm (range, 0.089-0.192 mm) and in vertical direction it was 0.15 ± 0.02 mm (range, 0.113-0.181 mm). One patient had mild vitreous hemorrhage and two other patients had high postoperative residual sphere and astigmatism, respectively. But no other serious complications were observed. CONCLUSION: Scleral suture fixation of foldable toric intraocular lens to correct corneal astigmatism can be a safe and effective alternative technique to manage traumatic aphakic eyes that lack adequate capsular support.

Abstract
PURPOSE The purpose of this study is to describe a new technique for small-incision scleral fixation of intraocular lens (IOL) using double 10-0 polypropylene sutures, and to report the outcomes of IOL position compared with intrascleral IOL fixation at 12-month follow-up. STUDY DESIGN A retrospective comparative study. METHOD This new technique, called double sutured scleral fixated-IOL (DSF-IOL), was created to help with long-term knots strengthening by applying double sutures to each IOL haptic using an augmented Clove-hitch knot instead of the conventional knots tied by single suture. The tilt and decenter of IOL were measured by Scheimpflug camera and other refractive outcomes were compared between two groups at 12-month follow-up. RESULTS This study consisted of 26 eyes (54.2%) from the DSF-IOL group, and 22 eyes (45.8%) from the intrascleral fixated IOL (ISF-IOL) group. No significant differences of mean absolute degree of IOL tilt (2.90 ± 0.77 vs 2.82 ± 0.72; p = 0.633) and IOL decenter (151.90 ± 59.80 vs 175.0 ± 73.14 microns; p = 0.265) were found between the two groups. Post-operative LogMAR visual acuity was not statistically different between the two groups (0.32 ± 0.17 vs 0.41 ± 0.19, p = 0.089). Early post-operative hypotony was only present in the ISF-IOL group (13.6%). CONCLUSION This study shows that DSF-IOL is as effective as ISF-IOL. This technique can be a simpler approach to optimize small-incision scleral fixation of IOL without the complications associated with intrascleral IOL fixation.

Abstract
OBJECTIVE To describe outcomes of combined pars plana vitrectomy (PPV) and trans-scleral 4-point suture fixation of a foldable Akreos AO60 intraocular lens (IOL) in eyes with subluxated or dislocated lens or IOL. METHODS Retrospective case series of 20 eyes of 18 patients who underwent this procedure with a minimum follow-up of 3 months. Outcome measures included final best-corrected Snellen visual acuity (BCVA), spherical equivalent (SE) and intraoperative and postoperative complications. RESULTS Mean age at surgery was 43.65 years. The commonest indication for surgery was post-traumatic subluxated or dislocated cataract. Mean BCVA improved from 6/24 preoperatively to 6/9 at final follow-up (p < 0.0001). Mean SE was 5.69 dioptres preoperatively and -1.32 dioptres postoperatively. There were no intraoperative complications. Postoperative complications included transient vitreous haemorrhage in one eye and cystoid macular oedema in one eye. Postoperative Pentacam analysis confirmed the absence of IOL tilt or decentration in six eyes. Mean follow-up was 8.9 months (range 3-30 months). CONCLUSION Trans-scleral 4-point suture fixation of a foldable Akreos AO60 IOL can be performed safely along with concurrent PPV across varying surgical indications resulting in a substantial improvement in visual acuity with minimal complications.
