23G微创系统联合超乳术治疗白内障合并玻璃体视网膜病变

目的：观察23G微创系统联合白内障超声乳化术治疗白内障合并玻璃体视网膜病变的疗效。

方法：采用计算机随机数字表法将96例白内障合并玻璃体视网膜病变患者103眼分为观察组(48例51眼)和对照组(48例52眼)。观察组患者予以23G微创系统联合超声乳化术和玻璃体切割术，对照组患者予以常规超声乳化术和玻璃体切割术。观察两组患者术前，术后1、3、6mo最佳矫正视力(LogMAR)、眼压、角膜散光度数等指标变化情况，记录术后并发症发生情况。

结果：术后1、3、6mo，两组患者视力(LogMAR)均较术前降低，且有逐渐降低趋势，差异有统计学意义(P<0.05)，观察组同时间点视力(LogMAR)均低于对照组，差异有统计学意义(P<0.05)，两组患者眼压均较术前降低，且有逐渐下降趋势，差异有统计学意义(P<0.05)，观察组同时间点眼压均低于对照组，差异有统计学意义(P<0.05)； 与术前比较，两组患者术后1、3mo角膜散光度数明显升高，差异有统计学意义(P<0.05)，术后6mo角膜散光度数逐渐降低至术前水平，观察组患者术后1、3mo角膜散光度数均低于对照组，差异有统计学意义(P<0.05)； 观察组患者术后并发症发生率低于对照组，差异有统计学意义(P<0.05)。

结论：微创系统联合超声乳化术治疗白内障合并玻璃体视网膜病变的疗效好于常规手术，有利于视力、眼压、角膜散光度数等恢复正常，且能减少术后并发症的发生。

Efficacy of 23G minimally invasive system combined with phacoemulsification for cataract complicated with vitreoretinopathy

AIM: To observe the efficacy of 23G minimally invasive system combined with phacoemulsification in the treatment of cataract complicated with vitreoretinopathy.

METHODS: Totally 96 cases(103 eyes)of patients with cataract and vitreoretinopathy were divided into observation group(48 cases 51 eyes)and control group(48 cases 52 eyes)by computer random number method. Observation group was given 23G minimally invasive system combined with phacoemulsification and vitrectomy, and control group was given conventional phacoemulsification and vitrectomy. The changes of best corrected visual acuity(LogMAR visual acuity), intraocular pressure and corneal astigmatism degree were observed before operation and at 1, 3 and 6mo after operation, and the complications were observed as well.

RESULTS:At 1, 3 and 6mo after operation, the LogMAR visual acuity in the two groups were lower than those before operation, and they were gradually decreased(P<0.05), and the LogMAR visual acuity in observation group at the same time point were lower than those in control group(P<0.05). The intraocular pressure in the two groups was lower than that before operation, and it was with a gradual decrease trend(P<0.05), and the intraocular pressure in observation group was lower than that in control group at the same time(P<0.05). Compared with before operation, the corneal astigmatism degree was increased significantly in the two groups at 1mo after operation(P<0.05), and was decreased gradually to preoperative level at 6mo after operation and the corneal astigmatism degree at 1mo and 3mo after operation in observation group was lower than that in control group(P<0.05). The incidence rate of postoperative complications in observation group was lower than that in control group(P<0.05).

CONCLUSION: The 23G minimally invasive system combined with phacoemulsification has better efficacy than conventional surgery in the treatment of cataract complicated with vitreoretinopathy, and it is beneficial to the restoration of visual acuity, intraocular pressure, and corneal astigmatism degree, and it can reduce postoperative complications.
