Outcomes after posterior fixation of iris–claw lens in aphakic eyes

To analyze and determine the postoperative visual acuity and complications after intraocular implantation of an iris-claw lens in aphakic patients.

Sri Devaraj Urs Medical College, Kolar, Karnataka, India.

Retrospective study.

Medical records of cataract and aphakic patients who underwent posterior fixation of iris claw lens over a five-year period were reviewed for collection and analysis of data.

The study comprised 138 eyes of 57.25% female and 42.75% male with mean age of 62.84 ± 8.649 years. The follow up period was 6 to 24 months. The mean preoperative CDVA was 0.44 ± 0.23 logMAR. After 1 year of follow up period the mean postoperative CDVA was 0.3 ± 0.15 logMAR which was statistically significant (p <0.05) when compared to the preoperative values. The final log MAR CDVA was good in 54.35%, better in 41.3% and worse in 4.35% eyes. In the study mean preoperative Spherical Equivalent (SE) was -2.22 ± 3.28 D and post-operative SE was -1.02 ± 2.78 D. There was significant decrease in SE postoperatively (P=0.01).

This study showed the merits of retrofixated iris claw lens over AC IOL and SF IOL in terms of simple technique, short learning curve, satisfying overall visual outcome, less risk of complications and good safety profile.
