目的 利用巩膜隧道亚大切口摘除Ⅳ级和Ⅴ级核白内障。方法 对155例(160眼)老年性、并发性白内障用巩膜隧道亚大切口摘除硬核白内障,植入人工晶体。结果 裸视视力术後第一天为0.1～0.6,平均0.3,≥0.3者68眼,占42.5％。术後1周平均视力为0.6(0.3～1.0),其中≥0.5者121眼,占75.6％。结论 巩膜隧道亚大切口摘除硬核白内障是一种安全,效果良好的手术方法,适合在基层医院推广。
Objective To study the removal of grade Ⅳ and Ⅴ nuclear cataracts by scleral tunnel submaxillary incision. Methods A total of 155 cases (160 eyes) of senile and complicated cataract were treated with scleral tunnel sub-maxillary incision for hard nucleus cataract implantation and intraocular lens implantation. Results The first day after operation was 0.1 ~ 0.6, with an average of 0.3, ≥0.3 68 eyes (42.5%). One week after surgery, the average visual acuity was 0.6 (0.3-1.0), of which 121 were ≥ 0.5, accounting for 75.6%. Conclusion Scleral tunnel submaxillary excision of hard cataract is a safe and effective surgical method, suitable for promotion in primary hospitals.
