Evaluation of corneal thickness and endothelial cells before and after excimer laser photorefractive keratectomy

G Cennamo et al. J Refract Corneal Surg. 1994 Mar-Apr.

Abstract

Background: The possible endothelial damage induced by photorefractive keratectomy was investigated in myopic eyes.

Methods: A morphometric analysis of the endothelial cells was performed in 19 patients before and 2 months after photorefractive keratectomy for the correction of various degrees of myopia. Central ultrasonic pachometry was also recorded at the same examination times.

Results: No significant changes (p = .816) of the endothelial cell density were found between preoperative and postoperative measurements. The pleomorphic index did not show any significant changes after treatment (p = .955). Central corneal thickness was reduced to a various extent (range from 50 microns to 250 microns) according to the amount of myopic correction intended.

Conclusions: Our preliminary data suggest that photorefractive keratectomy for the correction of myopia does not induce endothelial cell damage, at least in the short term.
