Purpose

To report visual and refractive outcomes in eyes that underwent intraocular lens (IOL) fixation in the absence of capsular support.

Setting

Tertiary specialized eye hospital

Methods

Retrospective charts review of cases undergoing posterior chamber iris fixated IOL (IFIOL) and scleral fixated IOL (SFIOL) implants from June 2014 to March 2020 with more than three months of follow-up and having preoperative best-corrected visual acuity of 20/60 and more

Results

Records of 120 eyes of 112 patients were reviewed. The mean age of the patients was 46.9 ± 22.3 (14.4–98.0) years old, and 62% (n = 70) of participants were male. Most of the eyes (102: 85%) were aphakic at the time of surgery. The mean follow-up was 22.95 ± 17.1 months. The efficacy index of sutured IFIOL and glued SFIOL outperformed sutured SFIOL at three months and final visits postoperatively (p-value < 0.001). All techniques studied here resulted in a similar safety index at three months (p-value = 0.4). The mean predictive error (postoperative spherical equivalent refraction minus intended target refraction) was +0.07 ± 1.5 D and -0.12 ± 1.4 D at three months and the final postoperative visit, respectively.

Conclusions

The studied techniques have relatively similar and predictable visual and refractive outcomes in this series. In addition, techniques involving a small corneal incision with foldable IOL fixation to the iris or scleral tissue have superior efficacy and safety indices compared to creating large corneoscleral wounds for rigid IOL fixation techniques
