摘要
目的分析合并浅前房的白内障超声乳化吸除术的难点,并探讨其预防措施。方法对行超声乳化吸除手术、中央前房深度<2.5mm的白内障患者70例89眼进行回顾性分析。结果术后1个月矫正视力1.0～1.2者20眼(22.5%),0.5～0.8者50眼(56.2%);中央前房深度术前(2.19±0.03)mm,术后平均加深(1.34±0.05)mm,差别有统计学意义(t=26.17,P<0.001);眼压均比术前明显下降[平均下降(4.18±0.58)mm Hg],手术前、后眼压比较差别有统计学意义(t=7.20,P<0.001);术后角膜可逆性水肿发生率为23眼(25.8%),其中Ⅲ级以下核组3眼(8.1%),Ⅲ级及其以上核组20眼(38.5%),所有病例角膜水肿均在手术后1周内恢复透明,均未出现严重并发症。结论合并浅前房的白内障行超声乳化吸除术手术难度大,强调切口规范,使用高质量黏弹剂,保持前房深度,应用拦截劈核技术、高负压吸引手法碎核,提高超声乳化操作的有效性,均是顺利完成手术的关键。同时强调合并浅前房的白内障患者应尽早手术,超声乳化吸除术是安全和有效的。
Objective To analyze the difficulties of phacoemulsification on the patients oI cataract with shallow anterxor chamber, and discuss its preventive measures. Methods We reviewed and analyzed 70 patients （89 eyes） with cataract whose center anterior chamber depth〈2.5 mm. All of them were performed the surgery of phacoemulsification and IOL implantation. Results One month after the surgery, BSCVA （best corrected visual acuity） Was 1.0 to 1.2 in 20 eyes （22.5 %）, and 0.5 to 0. 8 in 50 eyes （56.2%）. Preoperative central anterior chamber depth was （2.19±0.03） ram, postoperative mean depth increased （1.34±0.05） ram, and the difference was statistically significant （t= 26.17, P%0. 001）. The intraocular pressure decreased （4.18±0.58） mm Hg （t=7.20, P%0. 001）. Corneal reversible edema occured in 23 eyes （25.8%）, including 3 eyes （8.1%） in nuclear〈Ⅲgroup and 20 eyes （38.5%） in nuclear≥Ⅲ group. All the cases of corneal edema returned to transparent during one week. Conclusion It＇s emphasized that the correct technique of incision, application of stop and chop, lower energy and higher aspiration to break nucleus technique, with the help of high quality DisCoVisc, maintaining the maximum operating space are all the keys to the success of the surgery. The phacoemulsification and IOL implantation on the patients of cataract with shallow anterior chamber is safe and effective, and it＇s better to operate as early as possible.
