Abstract：
OBJECTIVE: To compare the outcomes of removing bandage contact lens (BCL) on days 3 and 5 after photorefractive keratectomy (PRK).
METHODS: One hundred patients who underwent PRK (a total of 200 eyes) were enrolled in the present study. The subjects were assigned to two groups. Group 1 consisted of the right eyes of subjects and bandage contact lenses removal were on the 3rd day; Group 2 consisted of the fellow eyes of same subjects and removed bandage contact lenses on the 5th day after PRK. Then, data obtained from both groups were compared. To evaluate complications, the subjects underwent a slit-lamp examination in all visits.
RESULTS: Filamentary keratitis was observed in one eye in both groups. The frequency of haze was higher in group 1; however, it was not significant between the two groups. Using mixed model analysis, significant differences were observed in the rate of complications as well as pain and eye discomfort scores between the groups (P < 0.05). No major complication was reported.
CONCLUSIONS: Majority of post-PRK corneal epithelial defect is healed on day 3. However, keeping BCL for 5 days postoperatively instead of the three days produces a slightly lower rate of total complication.

摘要：
目的：比较屈光性角膜切削术（PRK）后第3天和第5天摘除绷带隐形眼镜（BCL）的结果。
方法：本研究纳入了100名接受PRK的患者（共200只眼）。将受试者分为两组。第1组由受试者的右眼组成，第3天取下绷带隐形眼镜；第2组由同一受试者的同侧眼睛组成，在PRK后第5天取下绷带隐形眼镜。然后，比较两组的数据.为了评估并发症，受试者在所有访问中都接受了裂隙灯检查。
结果：两组均在一只眼睛中观察到丝状角膜炎。第1组的雾霾频率较高；然而，两组间无显著性差异.使用混合模型分析，两组并发症发生率、疼痛和眼部不适评分比较差异均有统计学意义(P<0.05)。无重大并发症报告。
结论：大多数PRK术后角膜上皮缺损在第3天愈合。然而,术后将BCL保留5天而不是3天，总并发症的发生率略低。
