The effect of hyperopic laser in situ keratomileusis on refractive accommodative esotropia.
To evaluate the efficacy of laser in situ keratomileusis (LASIK) for discarding spectacles and simultaneously correcting ocular alignment in patients with refractive accommodative esotropia. LASIK was performed on 20 eyes of 10 patients (mean age, 24.3 years; range, 11 to 43 years) using a Technolas 217C excimer laser. The target refraction was emmetropia. Visual acuity (uncorrected and best-corrected), refractive error, and ocular alignment were recorded before and after LASIK. Minimum follow-up was 12 months. The mean preoperative uncorrected and corrected angle of deviation was 37.1 prism diopters (PD) (range, 17 to 80; standard deviation (SD), 19.8)) and 14.74 PD (range, 0 to 50; SD, 12.9) of esotropia, respectively, which changed to 7.2 PD (range, 0 to 50; SD, 15.78) without correction postoperatively (p=0.005). Of 20 eyes, 15% lost one line of best-corrected visual acuity, 10% gained two lines, and 75% showed no change. LASIK could be considered an alternative treatment for patients with refractive accommodative esotropia with intolerance to glasses and contact lenses.
