A light adjustable IOL technology treated residual hyperopia errors while significantly improving uncorrected visual acuity and not altering best corrected visual acuity, a study found.

Researchers conducted a prospective, nonrandomized study examining postoperative results of 14 eyes of 14 patients who underwent cataract surgery and were implanted with a foldable posterior chamber UV-absorbing three-piece photoreactive silicone lens. Manifest refraction, UCVA and BCVA were measured

Thirteen eyes achieved ±0.25 D of target refraction at day 1 after lock-in. By 6 months postop, 100% of the eyes achieved the targeted refractive adjustment within 0.5 D or better.

"The data demonstrate the stability of the achieved refractive change after the adjustment and lock-in procedures," the study authors said. "The mean rate of change was 0.006 D per month, which is six times more stable than that of refractive procedures."
