目的探讨透明角膜切口超声乳化白内障摘除联合人工晶状体植入术的手术方法及疗效。方法对82例(86眼)白内障患者进行透明角膜切口的超声乳化白内障摘除术,全部病例均采用表面麻醉植入人工晶状体。术后观察手术反应、视力、角膜散光和并发症。结果术后随访:术后1周的裸眼视力在0.4以上者79眼占91.86%,术后1个月矫正视力在0.6以上者82眼占95.35%。术后1周平均散光为(0.98±0.82)D,比术前增加0.13D,(P>0.05)。术后1个月平均散光为(0.88±0.56)D,与术前无统计学差异(P>0.05)。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人工晶状体植入术具有安全、恢复快及视功能恢复好的特点。表面麻醉有一定的优势。
Objective To investigate the surgical method and efficacy of phacoemulsification with cataract extraction combined with intraocular lens implantation. Methods 82 cases (86 eyes) of cataract patients underwent open corneal incision phacoemulsification cataract extraction, all patients were implanted intraocular lens with surface anesthesia. Postoperative observation of surgical response, visual acuity, corneal astigmatism and complications. Results The postoperative follow-up showed that the uncorrected visual acuity of 0.4 or more in one week after operation was 91.86% in 79 eyes, corrected visual acuity was 0.6 or more in one month and 82 eyes accounted for 95.35%. The mean astigmatism in 1 week after operation was (0.98 ± 0.82) D, which was 0.13D more than that before operation (P> 0.05). The mean astigmatism at 1 month after operation was (0.88 ± 0.56) D, which was not significantly different from that before operation (P> 0.05). Common postoperative inflammatory response and nuclear hardness, phacoemulsification time and energy related to the size. Conclusions Transparent corneal incision cataract phacoemulsification with intraocular lens implantation under surface anesthesia is safe, rapid and recovery of visual function is good. Surface anesthesia has certain advantages.
