Effects of strabismus surgery on refraction in children.
We assessed 115 eyes of 59 children with esotropia 2-3 months postoperatively to evaluate the effects of strabismus surgery on refraction. Three variables were measured: spherical equivalent, and cylinder power and axis. The mean changes in spherical equivalent were non-significant. The axis of postoperative astigmatism moved towards 'with-the-rule', thus improving refraction. The amount of recession and the consequent changes in cylinder power were inversely related. The results showed a significant change in cylinder axis after recession of the inferior oblique. Recession-tucking procedures led to the largest changes in cylinder power.
