Introduction: With newer advances and improved techniques for implantation of posterior chamber intraocular lens (IOLs) in cataract surgery, the chances of encountering aphakia have reduced significantly. There is still a need to study secondary IOLs to deal with cases involving no or weak capsular support. In such cases, anterior chamber IOLs (ACIOL), iris-claw lens (ICL), or scleral-fixated IOLs (SFIOL) may be used. Excluding ACIOLS by virtue of higher complication rates, this study was done to explore the superiority of SFIOL and ICL. Aim: The aim of the study is to compare the visual outcome and complications of posterior ICL and SFIOL. Materials and Methods: It was a prospective interventional hospital-based study on 26 patients from the ophthalmology outpatient department fulfilling inclusion and exclusion criteria. Detailed history and ophthalmological examination was done for all patients and they were divided into two groups based on iris morphology. Of 26 aphakic patients, 13 were implanted with ICL and 13 with SFIOL by a single surgeon, and visual activity and complication rates in both the groups were compared. Results: There was a statistically significant difference in visual acuity (VA) on day 1 postoperative with 6/18 vision on Snellen's chart in ICL-implanted patient and 6/60 in SFIOL-implanted patients. However, best-corrected VA on the 45th day postoperative was comparable in both the groups. Complication-wise SFIOL group showed dreadful complication like retinal detachment, whereas ICL group presented maximally with immediate postoperative iritis and ovalization of the pupil as long-term complication which was harmless. Conclusion: Both ICL and SFIOL are good choices for secondary IOL implantation. Visual outcomes of both the lens were comparable on late follow–up; however, complication-wise ICL is preferred over SFIOL.
