目的 :讨论经上方角巩膜缘行长 5 1～ 5 7mm斜形自闭式切口的白内障超声乳化摘除及非叠式人工晶体植入术的方法和疗效。方法 :对 14 2例 ( 16 2眼 )白内障行上方角巩缘一次直接穿刺进入前房作 3 2mm斜形自闭式切口 ,超声乳化白内障摘除后扩大切口至 5 1～ 5 7mm ,并植入非折叠式光学直径 5 0～ 5 5mmPMMA人工晶体。结果 :术后裸眼或矫正视力 :术后 3天≥ 0 5为 75 1% ,术后 1周≥ 0 5为 89 3% ,0 5～ 0 9为 5 0 1% ,≥ 1 0为 39 2 % ;术后 1月≥ 1 0为 5 4 2 %。术后平均散光 :术后 1周为 1 0 2± 0 76D ,术后 1月为 0 96± 0 6 3D ,术后 6月为 0 82± 0 5 9D。结论 :上方角巩缘斜形自闭式切口白内障超声乳化人工晶体植入术后散光小 ,手术安全 ,切口自闭性能良好 ,愈合快
OBJECTIVE: To discuss the method and efficacy of phacoemulsification and non-superimposed intraocular lens implantation through a 51-157mm oblique incision on the upper limbal scleral margin. Methods: 14 2 cases (16 2 eyes) of cataracts were punctured into the anterior chamber with a 32 2 oblique incision. The phacoemulsification cataract extraction was performed to enlarge the incision to 51-57 mm and then implanted Non-folded optical diameter 5 0 ~ 5 5mmPMMA intraocular lens. Results: The postoperative uncorrected or corrected visual acuity was 75 1% ≥ 0 5 days after operation, 89 3% ≥ 0 5 at 1 week after operation, and 51 0% at 0 5 ~ 0 9 and 39 2 at ≥ 1 0 %; ≥1 0 after operation was 54.2%. The mean postoperative astigmatism was 1 0 2 ± 0 76D at 1 week after operation, 0 96 ± 0 6 3D at 1 month and 0 82 ± 0 5 9D at 6 months after operation. CONCLUSION: The astigmatic oblique edge of the upper limbic incision cataract phacoemulsification with intraocular lens implantation astigmatism is small, safe operation, incision autism performance is good, healing fast
