Abstract

Background:This study aims to evaluate the safety, effectiveness, and complication of
retro pupillary iris claw intraocular lens in aphakic patients with inadequate capsular
support.
Materials and Methods: This prospective interventional study was conducted in 40 eyes
of 40 patients between January 2019 to June2020. Surgical aphakia with inadequate
capsular support, Zonular dialysis, Posttraumatic subluxation of lens were
included.Preoperative and postoperative best corrected visual acuity(BCVA) and the
occurrence of various vision threatening complications such as iridocyclitis,decentration
of iris claw IOL,Cystoid macular edema,Raised IOPand Ovalization of pupil were
considered during the follow up period.
Results: Forty eyes of Forty patients who fulfilled the criteria were included.Indications
for posterior iris claw IOL in our study were surgical aphakia(30/40), Zonular
dialysis(6/40) and Post trauma(4/40).The mean follows up period was 6 to
12months.About 28 (70%) patients had improvement in vision with postoperative
BCVA 6/12-6/9,10(25%)patientshad visual improvement with postoperative BCVA of
6/18-6/36,and 2(5%)patients had avisual acuity with less than 6/60. Postoperatively
thirty eyes (75%) had no complaints, six eyes (15%) developed iridocyclitis, but all these
patients had responded to topical steroids and cycloplegics.Five eyes (12.5%) developed
raised IOP,five eyes (12.5%) developed Ovalization of Pupil,twoeyes (5%) developed
CME and One (2.5%) eye developed IOL decentration.
Conclusion: Posterior iris claw IOL implantation is safe, effective,and timely procedure
in aphakia with inadequate capsular support.
