To report the 2 year data after Laser Presbyopia Reversal (LAPR) on improving accommodation in presbyopic patients.
A prospective randomized study of 30 patients aged 50 to 64 years was performed. Four fornix based peritomies were created and an Erbium laser was used to create eight radial 4.5 mm incisions 0.5 mm posterior to the limbus at 1:30, 4:30, 7:30 and 10:30 on the sclera. Follow up visits were performed at 1 day, 1 and 2 weeks, and 1, 2, 3, 6, 9, 12, 18 and 24 months.
Nine patients were evaluated at the end of a 2 year series of standardized examinations. Pre-operatively, the average near uncorrected visual acuity was 0.605 ± 0.158, 0.613 ± 0.163, and 0.517 ± 0.132 ETDRS LogMAR for the first eye treated, the second eye treated and both eyes respectively. At the final post-operative evaluation, the average near uncorrected visual acuity was 0.230 ± 0.163, 0.229 ± 0.146, and 0.174 ± 0.130 LogMAR respectively. Ninety-seven percent (97%) read J3 or better at their last follow-up visit (28 out of 29 patients) and eighty-three percent (83%) read J2 or better at the same visit (24 out of 29).
LAPR appears to show promise in improving uncorrected near visual acuity and amplitude of accommodation in the presbyopic patient population. Patients had immediate effects with no long term adverse consequences.
