title: Comparison between the effect of two different widths of circular lamellar keratectomy on refraction and corneal curvature in rabbits' eyes.
abstract: Twenty rabbits' eyes were subjected to circular lamellar keratectomy. Two trephines were used to mark rings at a depth of 0.3 mm, and the lamellar cornea in between was removed. A 1-mm-wide ring was removed from the right eyes, and a 0.5-mm-wide ring from the left ones. We found that removing a 1-mm ring more effectively corrected hypermetropia (3.09 +/- 1.72 diopters) than removing a 0.5-mm ring (1.81 +/- 0.95 D).
