A study of outcome of posterior iris-claw lens at tertiary health care center
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 4
Abstract
Background: The absence of adequate capsule support, complicates intraocular lens implantation at the time of penetrating keratoplasty. In such cases, an iris-supported anterior or posterior chamber intraocular lens, or a trans-sclerally sutured, fibrin glue-assisted sutureless lens can be implanted. Each of the available options has its own risks and complications. Posterior iris-claw lens implantation has the advantage of preserving the natural anatomy of the eye and seems to be an ideal alternative to overcome these complications. The present study was undertaken to evaluate the outcome of posterior iris-claw lens in different aphakic situations without adequate capsular support. Material and Methods: In this prospective study conducted at a tertiary care center, 70 aphakic eyes of 70 patients of the age group 35-75 years were enrolled. Posterior iris‐ fixated IOL was implanted all cases. Postoperative follow‐up was done by a single observer on day 1, day 7, 1 month, 3 months and 6 months for visual acuity, anterior chamber reaction, IOP, specular microscopy, OCT was completed by all patients. Results: Majority of patients (57% of the cases) were in the age group 60–70 years. The ECD changes after 6 months was statistically significant. The mean postoperative cell density at 6 months was 1243.51. Percentage of endothelial cell loss was 8.12%. Visual outcome at 6 months was as per the WHO guidelines. 88% of the patients, had visual acuity of 20/40 or better. None of the patient had any major complication. Discussion: The complications related to posterior iris-claw lens implantation were minimal compared with its benefits. Therefore, use of posterior iris-claw lens implantation for secondary implantations is a better option to the scleral-fixed or an angle-fixated IOL implantation.
