Abstract

PURPOSE:

To evaluate the efficacy and safety of the toric Implantable Collamer Lens phakic intraocular lens (pIOL) in the management of myopic astigmatism in Indian eyes.

SETTING:

Tertiary eyecare center, South India.

DESIGN:

Retrospective interventional case series.

METHODS:

The study included consecutive patients with myopic astigmatism with a minimum follow-up of 1 year. Safety, efficacy, predictability, and adverse events were assessed preoperatively and 12 months postoperatively.

RESULTS:

The study enrolled 110 eyes (65 patients). The mean corrected distance visual acuity was 0.23 logMAR ± 0.23 (SD) preoperatively and 0.18 ± 0.18 logMAR 12 months postoperatively (P<.001). The mean refractive cylinder decreased from 2.3 ± 1.1 diopters (D) to 0.4 ± 0.6 D, respectively (P<.001). Postoperatively, the uncorrected distance visual acuity improved to 20/20 in 15 eyes (13.6%) and 20/40 or better in 72 eyes (65.4%). Fourteen eyes (12.7%) gained 2 or more lines of corrected distance visual acuity, 21 eyes (19.1%) gained 1 line, 61 eyes (55.5%) had no change, and 1 eye (0.9%) lost 2 lines. Predictability within ±0.50 D of cylinder was achieved in 77 eyes (70 %) and within ±1.00 D in 97 eyes (88.2%). Twelve months postoperatively, the safety index was 0.75 and the efficacy index was 1.04. Endothelial cell loss at the end of 12 months was 10.3%. Clinically significant cataract developed in 1 eye (0.9%).

CONCLUSION:

Implantation of posterior chamber toric pIOLs to correct myopic astigmatism was effective, safe, and predictable.
