Refractive lens exchange can correct high levels of myopia with a low rate of ocular morbidity, according to a retrospective study. Regular retinal exams are needed to prevent retinal detachments, the study authors said.

Adem Anil Kubaloglu, MD, and colleagues at the Kartal Education and Research Hospital, Turkey, conducted the study, which included 56 eyes of 30 patients who underwent small incision refractive lens exchange to correct 12 D or more of myopia. A low-power posterior chamber IOL was implanted, and patients were followed for a mean 40.2 ± 11.9 months.

According to the study, uncorrected visual acuity improved in 94.6% of eyes. Best-corrected visual acuity (BCVA) improved in 37 eyes (66%), of which 27 (48.2%) gained two or more lines.

The authors noted that 58.9% of eyes had BCVA of 20/40 or better at last follow-up, compared to 26.7% of eyes preoperatively. Thirty-eight eyes (67.8%) were within ±1 D of targeted refraction, and 52 (92.8%) were within ±2 D.

There was one case (1.7%) of posterior capsular tear with vitreous loss (1.7%), and two eyes (3.5%) experienced retinal detachment.

The study is published in the European Journal of Ophthalmology.
