“…However, both the sutureless Yamane technique and lens insertion and fixation of the enVista MX60 IOL are known to be technically difficult and therefore may not be the first choice in a trainee-performed procedure. 31 , 32 Additionally, the Yamane technique is known to cause postoperative complications such as lens decentration and tilt. Due to the four eyelets on the Akreos AO60 IOL, it is relatively easy to center the lens during insertion and there is a lower risk of lens tilt compared to other techniques.…”

Purpose To evaluate the outcomes of a 4-point scleral-fixated foldable Akreos AO60 intraocular lens (IOL) insertion using Gore-Tex suture performed by trainees under supervision of a single attending surgeon. Methods Retrospective chart review for 53 eyes of 50 patients whose surgery was performed by trainees under supervision of a single surgeon between 2015 and 2018 at a tertiary care hospital (Johns Hopkins Wilmer Eye Institute, Baltimore, MD). Indications for surgery, preoperative risk factors, and intraoperative techniques were analyzed. Outcome measures included final best-corrected visual acuity (BCVA), change in BCVA, difference between expected and final spherical equivalent (SE), and postoperative complications. Results Mean patient age was 62.8 years (range 26.9 to 88.4). The most common indication for surgery was IOL dislocation (59.6%) due to trauma in 21 cases (40.4%) and pseudoexfoliation in 6 (11.5%). Combined pars plana vitrectomy was performed simultaneously in 46 cases (88.5%). Mean BCVA improved from 20/100 to 20/40 (p < 0.001). The difference between expected and final SE was within 1.0 D in 28 cases (53.8%). Postoperative hypotony occurred in 12 eyes (21.2%) on day 1; all were resolved at last follow-up. Postoperative cystoid macular edema (CME) occurred in 20 cases (38.5%); 11 (21.2%) persisted through last follow-up. Conclusion Scleral-fixation of Akreos AO60 IOL in absence of capsular support can be performed by trainees under supervision and results in effective visual rehabilitation. Postoperative CME occurred at a higher rate than previously reported in the literature. Future studies should assess the rates of postoperative complications amongst different techniques of secondary IOL fixation performed by trainees to determine which is the safest.

BACKGROUND AND OBJECTIVE: No consensus exists on the comparative efficacy and safety of sutured scleral-fixated (SSF) and anterior chamber (AC) intraocular lens (IOL) implantation. We aim to compare outcomes of these two techniques. PATIENTS AND METHODS: A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was conducted (2005 to 2020). Studies comparing SSFIOLs with ACIOLs were included. Outcomes included corrected distance visual acuity and complications. A meta-analysis was conducted with a random effects model. Weighted mean differences and risk ratios with 95% CIs were computed. RESULTS: Seven hundred eighty-three eyes from nine studies were included. SSFIOLs had a significantly higher absolute postoperative spherical equivalent (weighted mean difference, 0.32; 95% CI, 0.03 to 0.60; P = .03; low certainty) and incidence of IOL decentration/subluxation (risk ratio, 2.69; 95% CI, 1.03 to 7.01; P = .04; moderate certainty) than ACIOLs. There was no difference in final corrected distance visual acuity ( P = .26). CONCLUSIONS: SSFIOLs have a higher absolute postoperative spherical equivalent and incidence of IOL decentration/subluxation than ACIOLs. Future prospective studies are needed to confirm these findings. [ Ophthalmic Surg Lasers Imaging Retin a. 2022;53:12–21.]

Context DMEK is used to treat corneal decompensation. This study focuses on the succcess and outcome of DMEK with and without secondary IOL implantation. Aims The purpose of our work is to evaluate Descemet membrane endothelial keratoplasty (DMEK) with secondary Intraocular lens (IOL) implantation in cases of aphakic bullous keratopathy with insufficient capsular support. Settings and design Pilot study. Methods and material This was a nonrandomized comparative prospective interventional case series where 11 eyes of 11 patients with aphakic bullous keratopathy secondary to complicated cataract surgery underwent DMEK with secondary IOL implantation using modified Yamane technique, and results were compared to 11 eyes of 11 patients underwent DMEK only. Statistical analysis used The statistical analysis was conducted using the Statistical Package for Social Sciences (SPSS 15.0.1 for windows; SPSS Inc, Chicago, IL, 2001). Results Both groups showed a high success rate (81.8%) with rebubbling required in 3 eyes in both groups. Both groups also showed significantly improved BCVA, decreased CCT and a decrease in donor graft ECD. Conclusions DMEK combined with secondary IOL implantation by modified Yamane technique appears to be a feasible method in managing aphakic bullos keratopathy with inadequate capsular support, and results are comparable to DMEK alone.
