透明角膜切口超声乳化折叠人工晶状体植入术138例分析

Phacoemulsification and foldable IOL implantation with clear corneal incision

目的 探讨透明角膜小切口白内障超声乳化及折叠式人工晶状体植入术的手术方法及疗效。 方法 对138例 (16 8眼 )白内障病人进行透明角膜切口的超声乳化白内障摘出术 ,全部病例均采用表面麻醉及植入折叠式人工晶状体 ,术后观察手术反应、视力和并发症。 结果 术后随访第 1天的裸眼视力在 0 4以上者有 15 7眼 ,占 93 45 % ,术后1周和术后 1个月的矫正视力在 0 5以上者分别为 15 2眼 (90 48% )和 16 0眼 (95 44% )。术后常见的炎症反应主要与核的硬度、超声乳化的时间及能量的大小有关。 结论 在表面麻醉下行透明角膜切口的白内障超声乳化及植入折叠式人工晶状体手术具有安全、恢复快及视功能恢复好的特点 ,表面麻醉具有一定的优势。

Objective To estimate the method and effect of the phacoemulsification and foldable intraocular lens implantation through a small clear corneal incision. Methods 138 cases of patients (168?eyes)with cataract includes the senile cataract.Complicated cataract,and traumatic cataract were operated with phacoemulsification and foldable IOL implantation through a clear corneal incision under topical anaesthesia.The visual acuity and the complications were observed postoperatively. Results Postoperatively,the uncorrected visual acuity was 0 4 in 157?eyes(93 45%) on d?1.The corrected visual acuity 0 5 or better after the first week and first month were achieved in 152?eyes(90 48%) and 160?eyes(95 24%),respectively.The inflammatory reaction after operation was associated with the hardness of the nuclei,the time and the power of phaco. Conclusion Phacoemulsification with foldable lens implantation through a clear corneal incision under the topical anaesthesia was a safe and effective method for the treatment of the cataract.The advantages and the technique of the topical anaesthesia used during the phacoemulsification was discussed in detail.
