Iris-clip versus iris-claw intraocular lenses

Visual rehabilitation in aphakia has been a challenge with a wide variety of surgical options available for ophthalmologist. We report the visual outcome with retropupillary iris claw lens secondary to intra operative complications and secondary implantation in aphakia. An interventional study on 4 eyes of 4 patients was conducted. Preoperative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome measure was best-corrected visual acuity and secondary postoperative complication was recorded at various intervals. All patients had visual acuity of ≥6/18 postoperatively. Sutureless retropupillary iris claw intraocular lens implantation is a good alternative of scleral-fixated intraocular lenses in aphakic patients.

Purpose: To evaluate the visual outcomes, safety, efficacy, and causes of bilensectomy for iris fixated phakic intraocular lenses (pIOLs). Methods: This was a two center consecutive retrospective study that included 43 eyes that underwent iris-claw pIOL bilensectomy. Patients with follow up less than 4 months were excluded from the study. Uncorrected, corrected visual acuity (UCVA, CDVA), refractive outcomes, efficacy, safety (number of eyes in which the postoperative CDVA was worse than the preoperative CDVA), endothelial cell density (ECD), causes of bilensectomy, the time between the implantation of the pIOL and bilensectomy, intra and postoperative complications were analyzed. Results: There was a statistically significant improvement in UCVA and CDVA after surgery ( p = 0.001). The efficacy index was 0.7, four eyes had a postoperative CDVA worse than the preoperative CDVA. The mean spherical equivalent 1 year after bilensectomy was −0.78 ± 1.70 D. There was a statistically significant endothelial cell loss after iris claw lens bilensectomy ( p = .003). Cataract development and endothelial cell loss were the only reasons for bilensectomy. The mean time between pIOL implantation and bilensectomy was 12.2 ± 5.5 years. One patient had corneal edema 8 months after surgery and one had a retinal detachment 11 months after surgery. Conclusion: Bilensectomy was successful in improving UCVA and CDVA with an acceptable refractive outcome. Significant loss of ECD was found after surgery. The results recommend a larger ACD as selection criteria when choosing to implant an Artisan lens, and a close postoperative monitoring of the endothelial cell count.

Aims: To evaluate the visual outcomes and complications after implantation of retrofixated iris claw (RFIC) lens in various challenging situations. Settings and Design: Retrospective, single centre, 8 year clinical audit. Materials and Methods: A retrospective analysis of cases who underwent RFIC lens implantation alone (group 1) or in combination with vitreoretinal (VR), corneal or glaucoma procedures (group 2) was performed. The main outcomes evaluated were corrected distant visual acuity (CDVA) and postoperative complications. The mean follow up was 13.09±6.8 (range 6-24) months. Results: The study involved 100 eyes of 83 patients with mean age of 51.1±25.4 years. Group 1 included 59 eyes and group 2 had 41 eyes. In group 1, the mean CDVA improved from 0.86±0.81 to 0.38±0.51 LogMAR (p<0.001) with 72.8% eyes having gain in lines (≥ 2 lines) of CDVA with safety index of 1.73. The mean CDVA in group 2 improved from 0.71±0.65 to 0.38±0.34 LogMAR (p=0.003) with 65.8% eyes having gain in lines (≥ 2 lines) of CDVA with a safety index of 1.54. Group 2 showed a higher complication rate of 36.59% compared to group 1 (20.34%). Significant complications noted were secondary glaucoma (8%), disenclavation of haptic (4%), subluxation of RFIC lens (1%). Conclusion: The visual outcome with RFIC lenses when combined with other intraocular procedures is mainly affected by the complexity of co-existing pathologies .The complications are more related to the combined procedures performed rather than RFIC lens implantation alone. This may still be acceptable when complication profile of other intraocular lenses is evaluated in similar challenging situations.
