目的观察准分子激光上皮下角膜磨镶术(LASEK)在治疗成年人屈光性弱视中的作用。设计前瞻性病例系列。研究对象55例(97眼)行LASEK治疗的屈光性弱视患者。方法记录上述患者LASEK手术前后最佳矫正视力(BCVA)、屈光度变化,并进行比较分析,术后随访1年。主要指标手术前后BCVA及屈光度。结果术后1周所有患者裸眼视力(UCVA)均明显提高,8眼(8.25%)超过术前BCVA。术后1个月BCVA由术前(0.51±0.12)提高到(0.61±0.16),两者相比具有显著性差异(P=0.000),且26眼(26.80%)UCVA>0.8。3个月时视力基本稳定,81眼(83.51%)超过术前BCVA,40眼(41.24%)UCVA>0.8。术后6个月(0.71±0.18)与术后1年(0.72±0.18)比较差异无统计学意义(P=0.610)。术后1周时复查患者出现轻度远视,术后1周等效球镜值(+1.25±0.48)D,1个月等效球镜值(+0.99±0.45)D,在术后3个月屈光度值预期基本接近;术中及术后无严重并发症发生。结论 LASEK可以有效矫正成年人屈光性弱视的屈光度,提高矫正视力,可以明显改善弱视。
Objective To observe the role of laser subepithelial keratomileusis (LASEK) in the treatment of refractive amblyopia in adults. Design prospective case series. Participants 55 patients (97 eyes) underwent LASEK treatment of refractive amblyopia patients. Methods The best corrected visual acuity (BCVA) and refractive power before and after LASEK operation were recorded and compared. The patients were followed up for 1 year. The main indicators before and after BCVA and refraction. Results All patients underwent unilateral visual acuity (UCVA) 1 week after operation. All of them were significantly higher than the preoperative BCVA in 8 eyes (8.25%). The BCVA increased from (0.51 ± 0.12) to (0.61 ± 0.16) at 1 month after operation, with significant difference (P = 0.000) and 26 eyes (26.80%) UCVA> 0.8.3 months Visual acuity was basically stable at 81 eyes (83.51%) over preoperative BCVA and 40 eyes (41.24%) with UCVA> 0.8. The difference was not statistically significant at 6 months (0.71 ± 0.18) and 1 year after surgery (0.72 ± 0.18) (P = 0.610). At 1 week after operation, mild hyperopia was observed in the patients. The equivalent spherical diameter at 1 week (+ 1.25 ± 0.48) D, the equivalent spherical diameter at 1 month (+ 0.99 ± 0.45) D, Monthly refractive power is expected to be close to; no serious complications during and after surgery. Conclusion LASEK can effectively correct the refraction of refractive refractive amblyopia in adults, improve visual acuity, can significantly improve the amblyopia.
