A Randomized,Comparative Study of Fluorometholone 0.2% and Fluorometholone 0.1% Acetate after Photorefractive Keratectomy

Abstract

Purpose

To compare the efficacy and tolerance of fluorometholone 0.1% acetate and fluorometholone 0.2% eyedrops in the postoperative management of photorefractive keratectomy (PRK).

Methods

A randomised single-blind comparative study was performed on two groups of 30 patients who underwent myopic PRK. The first group was given fluorometholone 0.1% acetate and the second fluorometholone 0.2%. Uncorrected and best corrected visual acuity, haze, IOP and local tolerance were evaluated. Statistical analysis was done using parametric and non-parametric tests.

Results

Visual acuity did not differ in the two groups; both were homogeneous as far as refractive error and haze were concerned. Three patients (10%) treated with fluorometholone 0.2% and two patients (6.6%) with fluorometholone 0.1% acetate developed ocular hypertension, but this was not statistically significant.

Conclusions

Fluorometholone 0.1% acetate was effective on inflammation after PRK, with the same efficacy as fluorometholone 0.2%.
