MI60人工晶体对高度近视白内障患者人工晶状体植入术后前房深度及视力水平的影响分析

Effect of MI60 intraocular lens on anterior chamber septh and visual acuity of cataract patients with high myopia after intraocular lens implantation

目的探究MI60人工晶体对高度近视白内障患者人工晶状体植入术后前房深度及视力水平的影响。方法选取2017年1月至2018年8月本院眼科收治的60例高度近视白内障患者为研究对象,采用随机数字表法分为观察组(30例,46眼)和对照组(30例,42眼)。两组患者均行白内障超声乳化术联合人工晶状体植入术,观察组患者使用MI60人工晶状体,对照组患者使用MA60MA人工晶状体。观察两组患者术前、术后6个月前房深度、眼压、最佳矫正视力(BCVA)等指标,比较术后并发症发生情况。结果术后6个月,观察组前房深度(4.82±0.45)mm,高于对照组(4.31±0.39)mm,差异有统计学意义(P<0.05);观察组手术前后前房深度差值(1.88±0.15)mm,高于对照组(1.42±0.12)mm,差异有统计学意义(P<0.05);观察组术前、术后6个月眼压分别为(15.21±3.06)mmHg、(14.87±3.31)mmHg,与对照组(15.45±2.88)mmHg、(15.06±3.18)mmHg比较,差异均无统计学意义(均P>0.05);术后6个月,观察组BCVA<4.5、4.6~4.7、>4.7发生率分别为10.87%、54.35%、34.78%,与对照组7.14%、61.90%、30.95%比较,差异均无统计学意义(均P>0.05);观察组术后并发症发生率4.35%,低于对照组23.81%,差异有统计学意义(P<0.05)。结论高度近视白内障患者在人工晶状体植入术中采用MI60人工晶状体与MA60MA人工晶状体对视力水平改善程度较为一致,但MI60人工晶状体可维持更深的前房深度,并减少术后并发症发生。

Objective To investigate the effects of MI 60 intraocular lens on anterior chamber depth and visual acuity of patients with high myopia cataract after intraocular lens implantation. Methods Using prospective study method, 60 patients with high myopia cataract were divided into and observation group (30 cases, 46 eyes) and a control group (30 cases, 42 eyes). Both groups performed cataract phacoemulsification and intraocular lens implantation. The observation group used MI 60 intraocular lens, and the control group MA60MA intraocular lens. The postoperative complications as well as the anterior chamber depth, intraocular pressure, and BCVA before and 6 months operation were compare between the two groups. Results 6 months after operation, the anterior chamber depth was (4.82 ± 0.45) mm in the observation group(4.31±0.39)mm (P < 0.05). The difference of anterior chamber depth between before and after operation was greater in the observation group than in the control group [(1.88 ± 0.15) mm vs.(1.42 ± 0.12) mm, P < 0.05)]. The pre- and post-operative intraocular pressures of the observation group were(15.21 ± 3.06) mmHg and (14.87 ± 3.31) mmHg, and those of the control group (15.45 ± 2.88) mmHg and(15.06 ± 3.18) mmHg (P > 0.05). 6 months after surgery, the incidences of BCVA < 4.5, 4.6 to 4.7, and > 4.7 were 10.87%, 54.35%, and 34.78% in the observation group, and were 7.14%, 61.90%, and 30.95% in the control group (P > 0.05). The incidence of postoperative complications was significantly lower in the observation group than in the control group (4.35% vs. 23.81%, P < 0.05). Conclusions MI60 IOL and MA60MA IOL are consistent in the improvement of vision in patients with high myopia taking cataract implantation, but MI 60 IOL maintains a deeper anterior chamber depth and reduces postoperative complications.
