Forty patients in group 1 were given eye gel containing sodium hyaluronate, xanthan gum, and netilmycine, and 40 patients in group 2 were given one drop of eye gel containing fusidic acid. The patients in both groups were examined at the 12th, 24th, and 48th hours in the postoperative period by using slit-lamp technique. The subjective complaints of the patients such as pain and stinging, and the recovery periods of the corneal epithelial defect were evaluated comparatively by fluorescein staining.Results: The mean ages were 26±8 years (range: 18–35) and 24±6 years (range: 18–33) in groups 1 and 2, respectively. The closure period of the corneal epithelial defect was observed as 24±8 hours (range: 16–42) and 36±12 hours (range: 18–48) in groups 1 and 2, respectively. The number of the patients suffering from subjective complaints such as pain and stinging in the first 12 hours was six and 29 in groups 1 and 2, respectively. The difference was significant both clinically and statistically (P=0.001).Conclusion: Combined eye gel containing hyaluronate, xanthan gum, and netilmycine accelerates the recovery of corneal epithelial defect and reduces the complaints of the patients, when compared to the fusidic acid gel. Combined eye gel should be considered as an option for the treatment of the corneal epithelial defect related with pterygium surgery.
