Comparison of Samfilcon A and Lotrafilcon B silicone hydrogel bandage contact lenses in reducing postoperative pain and accelerating re-epithelialization after photorefractive keratectomy

Purpose To compare the efficacy of Samfilcon A and Lotrafilcon B bandage contact lenses after photorefractive keratectomy (PRK). Methods In this study, patients with bilateral PRK were assigned for the fitting of Lotrafilcon B lens and Samfilcon A lens. The patients were examined on the day of surge...

Description
Summary:Purpose To compare the efficacy of Samfilcon A and Lotrafilcon B bandage contact lenses after photorefractive keratectomy (PRK). Methods In this study, patients with bilateral PRK were assigned for the fitting of Lotrafilcon B lens and Samfilcon A lens. The patients were examined on the day of surgery and on postoperative days 1, 2 and 3. Slit biomicroscopy was performed to assess epithelial defect size in the postoperative examinations. The subjective evaluation of pain and visual symptoms was recorded on postoperative days 1, 2 and 3. Results Analysis was made of 68 eyes of 34 patients who fulfilled the criteria and had PRK for correction of low to moderate myopia/astigmatism. On postoperative days 1 and 2, pain and epiphora scores were significantly lower in eyes with Samfilcon A lens ( p
