To compare the efficacy of bandage contact lenses with two different base curves in promoting epithelial healing after epithelial laser in situ keratomileusis (epi-LASIK).
A prospective, observer-masked study was conducted in 27 patients. Each patient randomly received one bandage contact lens with an 8.4-mm base curve in one eye and one with an 8.8-mm base curve in the fellow eye. Corneal epithelial status, pain score, spherical equivalent, and uncorrected visual acuity (UCVA) were examined during the first postoperative month.
Corneal epithelial status, postoperative pain, and spherical equivalent were similar for both lenses during the first postoperative month. The eyes with lenses with an 8.8-mm base curve had better UCVA on postoperative day (POD) 4, but there was no significant difference in UCVA after POD 7. In the patients with preoperative low to moderate myopia and low keratometric values (<43.0 D), there was no significant difference in the postoperative UCVA between the lenses. On the other hand, in patients with preoperative high myopia and high keratometric values (> or =43.0 D), UCVA was better in eyes with lenses with an 8.8-mm base curve on POD 4.
These findings suggest that the base curves of bandage contact lenses affect visual rehabilitation after epi-LASIK, particularly in patients with a steep cornea and high myopia.
比较两种不同基弧的绷带式隐形眼镜在准分子激光上皮下角膜磨镶术（epi-LASIK）后促进上皮愈合的疗效。
对27例患者进行前瞻性、观察者盲法研究。每位患者一只眼随机佩戴基弧为8.4毫米的绷带式隐形眼镜，另一只眼佩戴基弧为8.8毫米的绷带式隐形眼镜。在术后第一个月内检查角膜上皮状态、疼痛评分、等效球镜度和裸眼视力（UCVA）。
术后第一个月，两种镜片的角膜上皮状态、术后疼痛和等效球镜度相似。基弧为8.8毫米的镜片组在术后第4天的UCVA更好，但术后第7天之后UCVA无显著差异。术前为低度至中度近视且角膜曲率值较低（<43.0 D）的患者，两种镜片术后的UCVA无显著差异。另一方面，术前为高度近视且角膜曲率值较高（≥43.0 D）的患者，基弧为8.8毫米的镜片组在术后第4天的UCVA更好。
这些发现表明，绷带式隐形眼镜的基弧会影响epi-LASIK术后的视力恢复，尤其是在角膜陡峭和高度近视患者中。
