LLRM Medical College, Meerut. Group I patients underwent secondary implantation with AC IOL (Kelman Z type AC IOL). Group II patients underwent secondary implantation with scleral fixated IOL

47 For more than 2 decades, anterior chamber IOLs (AC IOLs) and for more than a decade scleral-fixated posterior chamber (PC) IOLs has been predominant type of lens used in secondary IOL implantation in the absence of capsule support. For the past decade surgeons around the globe have also tried sulcus fixation of a standard PC IOL as a treatment modality in cases with nucleus or IOL drop with intact capsulorrhexis margin. Secondary sulcus fixated lenses have been used in children with unilateral aphakia with intact capsular support. Scleral-fixated PC IOL implantation is successful even in aphakic children with no capsular support. All these techniques have advantages and pitfalls, and the indications, lens style, techniques, and incidence of complications with each IOL type remains controversial. Implantation of modern, open-loop, AC IOLs has regained popularity and is a valuable alternative to scleral-fixated PC IOLs and sulcus fixated lenses are most preferred over the other two. Although these 3 major approaches are available for secondary IOL implantation in aphakic eyes with inadequate capsule support, no consensus exists on the indications and relative efficacy and safety of these. The purpose of this study is to evaluate the visual outcomes and complication profiles of secondary implantation of open-loop anterior chamber, sulcus fixated posterior chamber and scleral fixated posterior chamber intraocular lens.
