Abstract
PURPOSE: To evaluate improvement in best spectacle-corrected visual acuity (BSCVA) after laser in situ keratomileusis (LASIK) in adult patients with amblyopia. SETTING: Refractive Eye Surgery Center, Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA. METHODS: The charts of consecutive patients with a diagnosis of amblyopia at the time of refractive evaluation who had LASIK were reviewed retrospectively. The preoperative and postoperative uncorrected visual acuity (UCVA) and BSCVA were analyzed. RESULTS: Twenty-one eyes of 19 patients were identified as having amblyopia and LASIK surgery. Eight patients (42.1%) were diagnosed with amblyopia only, 6 patients (31.6%) had anisometropic amblyopia, 4 patients (21.1%) had strabismic amblyopia, and 1 patient (5.2%) had anisometropic and strabismic amblyopia. Eleven eyes (52.4%) had myopic astigmatism, 7 eyes (33.3%) were hyperopic, and 3 eyes (14.3%) had mixed astigmatism. Seven eyes (33.3 %) experienced more than a 1-line improvement in postoperative UCVA compared with the preoperative BSCVA. Nine eyes (42.8%) experienced more than a 1-line improvement in postoperative BSCVA compared with the preoperative BSCVA. The BSCVA was unchanged in 11 eyes (52.4%) and was worse by 2 lines in 1 eye (4.8%). CONCLUSION: After LASIK, the postoperative BSCVA was better than preoperatively in 42.8% of eyes with a history of amblyopia and the postoperative UCVA was better than the preoperative BSCVA in 33.3%.
