Abstract
Purpose: :
To determine the safety, efficacy, predictability, and stability of laser in situ keratomileusis (LASIK) to correct high anisometropia in patients 8 to 15 years old in whom conventional treatments have failed.
Methods: :
Nine eyes of nine patients (3 male and 6 female) with high anisometropia (>3.50 D), were included in this study. Minimum follow-up was 10 years. All patients were treated with the Chiron Technolas 217 excimer laser.
Results: :
Ten years after LASIK, best corrected visual acuity (BCVA) improved by at least one Snellen line in 5 eyes (55.5%). No eye lost any line of BCVA. Mean preoperative spherical equivalent refraction decreased from -7.66 to -2.33 D, mean astigmatism decreased from -3.11 to -0.75 D, and mean anisometropia decreased from 7.36 to 1.47 D. Four eyes (44.4%) were within +/-1.00 D of emmetropia. All patients were able to function binocularity.
Conclusions: :
In this study of selected patients 8 to 15 years old, LASIK was a safe and effective option for the correction of high anisometropia and for improve binocularity, when conventional therapies had failed.
