To assess the effect of preoperative topical nonsteroidal antiinflammatory drugs (NSAIDs) on postoperative pain after laser-assisted subepithelial keratectomy (LASEK) and to investigate their mechanism.

Prospective randomized clinical trial.
Participants in 2 related studies were assessed. Study 1 comprised patients scheduled for bilateral LASEK (Group 1) who were randomized to receive an NSAID in 1 eye and a placebo in the fellow eye 30, 20, and 10 minutes before LASEK. Postoperative pain, glare, tearing, and irritation were assessed using a visual analog scale. Study 2 comprised healthy subjects (Group 2) who were randomly divided into subgroups. The participants in these subgroups were randomized to receive ketorolac tromethamine 0.5% in 1 eye and placebo (ofloxacin 0.3%) in the fellow eye (Group 2A), proparacaine hydrochloride 0.5% in 1 eye and placebo in the fellow eye (Group 2B), or ketorolac tromethamine 0.5% in 1 eye and placebo in the fellow eye, followed 10 minutes later by 1 drop of proparacaine hydrochloride 0.5% in both eyes (Group 2C). In all 3 groups, corneal sensitivity was measured after 1, 2, and 6 hours.
The mean postoperative pain score in the NSAID-pretreated eye was statistically significantly lower than in the placebo-pretreated eye 6, 12, and 24 hours postoperatively (P < .05). The mean corneal sensitivity was statistically significantly lower in the NSAID-treated eye than in the placebo-treated eye at 1 and 2 hours in Groups 2A and 2C (P < .05).
Preoperative administration of topical NSAIDs before LASEK effectively reduces postoperative pain.

前瞻性随机临床试验。
对2项相关研究的参与者进行评估。研究1纳入计划行双眼LASEK的患者（第1组），随机分为在LASEK术前30、20和10分钟，一只眼使用NSAIDs，另一只眼使用安慰剂。使用视觉模拟量表评估术后疼痛、眩光、流泪和刺激症状。研究2纳入健康受试者（第2组），随机分为亚组。这些亚组的参与者被随机分为一只眼使用0.5%酮咯酸氨丁三醇，另一只眼使用安慰剂（0.3%氧氟沙星）（第2A组），一只眼使用0.5%盐酸丙美卡因，另一只眼使用安慰剂（第2B组），或一只眼使用0.5%酮咯酸氨丁三醇，另一只眼使用安慰剂，10分钟后双眼各滴入1滴0.5%盐酸丙美卡因（第2C组）。在所有3组中，分别于1、2和6小时后测量角膜敏感性。
NSAIDs预处理眼术后6、12和24小时的平均疼痛评分在统计学上显著低于安慰剂预处理眼（P < 0.05）。在第2A组和第2C组中，NSAIDs治疗眼在1和2小时时的平均角膜敏感性在统计学上显著低于安慰剂治疗眼（P < 0.05）。
LASEK术前局部应用NSAIDs可有效减轻术后疼痛。
