透明角膜3.2mm切口Phaco联合IOL植入术治疗白内障的疗效

目的：探讨3.2mm透明角膜切口白内障超声乳化吸除术(Phaco)联合人工晶状体(IOL)植入术治疗白内障的疗效。

方法：回顾性分析2015-10/2016-10我院眼科接诊的白内障患者95例107眼，均行3.2mm透明角膜切口Phaco联合IOL植入术，观察术后视力、角膜曲率、角膜散光、前房深度等情况。

结果：术后3d，1wk，1mo本组患者裸眼视力(0.16±0.06、0.15±0.05、0.14±0.04)明显优于术前(0.48±0.15)，前房深度(3.86±1.09、3.69±1.04、3.84±1.07mm)明显高于术前(2.71±0.88mm)(均P<0.05)，但角膜曲率和角膜散光度与术前无明显差异，且术后各时间点手术源性散光度无差异(均P>0.05)。

结论：3.2mm透明角膜切口Phaco联合IOL植入术可有效改善视力，减小角膜散光，是治疗白内障安全有效的手术方式。

Efficacy of Phaco combined with IOL implantation through 3.2mm transparent corneal incision in treatment of cataract

AIM: To explore the effect of 3.2mm clear corneal incision cataract phacoemulsification combined with intraocular lens(IOL)implantation.

METHODS: Retrospective analysis of 95 cases(107 eyes)cataract patients treated in our hospital, and all patients were given 3.2mm clear corneal incision Phaco combined with IOL implantation. The postoperative visual acuity, corneal curvature, corneal astigmatism, anterior chamber depth and complications were observed.

RESULTS: Postoperative 3d, 1wk, 1mo patients with the uncorrected visual acuity(0.16±0.06, 0.15±0.05, 0.14±0.04)were significantly better than preoperative(0.48±0.15). The anterior chamber depth(3.86±1.09, 3.69±1.04, 3.84±1.07mm)was significantly higher than the preoperative(2.71±0.88mm)(P<0.05), but there was no significant difference in corneal curvature and corneal astigmatism before operation. There was no difference in surgical astigmatism after operation(P>0.05).

CONCLUSION: 3.2mm clear corneal incision Phaco combined with IOL implantation can effectively improve the recovery of postoperative visual acuity and reduce the corneal astigmatism, and it is a safe and effective surgical treatment of cataract.
