LASIK effective for anisometropia in older children

GOIANIA, Brazil — LASIK appears to be a safe and effective option for correcting high anisometropia and improving binocularity in older children, according to surgeons here.
Belquiz R.A. Nassaralla, MD, PhD, and colleagues studied nine eyes of nine patients who had high anisometropia (>3.50 D). Mean patient age was 11.5 years, with ages ranging from 8 to 15.
Three months postop, uncorrected visual acuity (UCVA) improved by at least five Snellen lines in all patients. Three eyes were 20/40 or better without correction. Because of dense amblyopia, no eye had UCVA of 20/20 or better.
The mean spherical equivalent refraction decreased from -7.66 D preop to -0.22 D postop, and mean astigmatism decreased from -3.11 D preop to -0.69 D postop.
Postoperatively, eight eyes were within 1 D of emmetropia. Two eyes were within 0.5 D of the desired outcome.
Dr. Nassaralla notes that the 6-month and 12-month postop endothelial loss rates of 1.4% and 3.6% should be regarded with caution as an acceptable percentage, in that the losses were not statistically significant.
The study is published in the September/October issue of the Journal of Refractive Surgery.
