Abstract
PURPOSE: To explore whether hyperopic excimer corneal refractive surgery can affect ocular alignment and stereopsis in patients with both accommodative esotropia and amblyopia. METHODS: In this prospective study, 26 eyes of 13 patients with accommodative esotropia and amblyopia underwent bilateral hyperopic corneal refractive surgery: 9 patients underwent laser in situ keratomileusis (LASIK); 4, laser epithelial keratomileusis (LASEK). The main ocular examinations included pre- and postoperative best-corrected and uncorrected visual acuity, refractive error, ocular alignment, and stereopsis. RESULTS: Preoperative cycloplegic refraction in the right eyes was +5.64 ± 2.09 D; in the left eyes, +5.91 ± 1.97 D. After surgery, refraction in the right eyes was +1.13 ± 1.21 D; in the left eyes, +1.44 ±1.53 D. The mean logMAR uncorrected visual acuity was 0.46 ± 0.30 before surgery and 0.32 ± 0.25 after surgery (t = 5.72, P = 0.001). The mean pre- and postoperative best-corrected visual acuity were 0.31 ± 0.28 and 0.29 ± 0.25, respectively; there was no significant difference between the two groups (t = 1.23, P = 0.22). The average uncorrected esotropia was 37.92(Δ) ± 9.12(Δ) before surgery and 2.76(Δ) ± 2.80(Δ) after (P < 0.001). Using a synoptophore, 2 patients (15.3%) had preoperative stereopsis and 11 patients (84.6%) had postoperative stereopsis. No patients experienced lower stereopsis postoperatively. CONCLUSIONS: In this cohort, hyperopic corneal refractive surgery can improve the alignment, uncorrected visual acuity, and stereopsis in patients with accommodative esotropia and amblyopia.
