CARDIFF, England — Corneal sensitivity remains unchanged in patients with low hyperopia who have undergone photorefractive keratectomy, according to a study.

Paul Murphy, PhD, MCOptom, FAAO, and colleagues here at Cardiff University compared a control group of 17 patients who underwent no treatment to 11 patients who underwent PRK for the treatment of hyperopia ranging from +2 D to +4 D. Corneal sensitivity was assessed centrally and peripherally, at temporal, medial and inferior locations about 1 mm from the limbus. Measurements were taken preoperatively and at 1 and 2 weeks and 1, 3 and 6 months postoperatively for the PRK group.

No significant difference was found between the control group and the PRK group in preoperative sensation thresholds, and no significant changes were found between any of the test time periods at any of the four corneal test locations for the PRK group.

The study is published in the January/February issue of Journal of Refractive Surgery.
