Background: The modern cataract surgery involves implantation of posterior chamber intraocular lens (PCIOL) when the posterior capsule is intact. However, in case of weak or no capsular support, PCIOL implantation is not possible. In such situations, implantation of secondary Iris claw lens (ICIOL) or Scleral fixated IOL(SFIOL) remains as treatment options. The aim of this study was to compare the efficacy of ICIOL and SFIOL in terms of visual outcomes and complications in aphakic patients. Methods: This prospective randomized study was done from January 2019 to December 2019. Forty aphakic patients fulfilling inclusion criteria, who attended the ophthalmology outpatient department of VVPF’s Medical college and hospital, Ahmednagar were included in this study. These patients were randomly divided into two groups such as Group 1 included 20 patients who underwent ICIOL implantation and Group 2 included 20 patients who underwent SFIOL implantation. The preoperative and postoperative evaluation was done with visual acuity, slit-lamp examination, IOP, fundus examination for the follow up period of 6 months. Results were analysed with Chi square test and t-test using SPSS software. Results: 85% ICIOL and 80% of SFIOL patients had final Best Corrected Visual Acuity (BCVA) of 6/18-6/6. Surgical time in ICIOL was significantly less than SFIOL group (p=0.00). Suture related complications were significantly more in SFIOL group. However, oval pupil and pigment dispersion were seen more in ICIOL group but were harmless. One patient in SFIOL group developed Cystoid Macular Edema (CME) which persisted till final follow up and 1 haptic of ICIOL was disenclavated which was re-enclavated. Conclusion: Comparable final visual outcome was found between ICIOL group and SFIOL group. However, Implantation of ICIOL required less surgical time with fewer complications and hence is a better alternative to SFIOL implantation in correction of aphakia.
