Abstract |
Purpose: To compare of the pain after photorefractive keratectomy (PRK) according to two kinds of silicone hydrogel contact lenses. Methods: 92 eyes of 46 patients who underwent PRK surgery were prospectively investigated. Each patient was randomly assigned senofilcon A in one eye and lotrafilcon B in the other eye. Pain score (0-10) was assessed at postoperative day 0, 1, 2, 3 and 4 using visual analogue scale. Results: The pain scores (mean ± SD) of senofilcon A and lotrafilcon B were 1.6 ± 1.4, 2.2 ± 1.5 on postoperative day (POD) #0 (p = 0.0029), 2.9 ± 1.5, 3.7 ± 1.5 on POD # 1 (p = 0.009), 2.1 ± 1.2, 2.2 ± 1.4 on POD #2 (p = 0.6208), 0.5 ± 0.7, 0.7 ± 0.8 on POD #3 (p = 0.8375), and 0.1 ± 0.3, 0.1 ± 0.3 on POD #4 (p = 0.1332) respectively. Conclusions: Senofilcon A contributed to reduce postoperative pain effectively in patients undergoing PRK due to lens design, material and moisture-rich properties.
