摘要
目的评估巩膜反眉弓小切口超声乳化联合聚甲基丙烯酸甲酯(PMMA)硬质人工晶状体植入术在大范围扶贫白内障手术中的应用效果。方法回顾性分析2018年1月至2018年8月该院收治的60例(60眼)老年性白内障临床资料。患者随机分为两组。A组,30眼,行巩膜反眉弓隧道式小切口,超声乳化吸出后扩大切口至5.5 mm,植入硬质PMMA人工晶状体。B组,30眼,行透明角膜切口,超声乳化吸出后扩大切口至5.5 mm,植入硬质PMMA人工晶状体。对比分析术后两组角膜散光度、视力及并发症。结果B组术后1周、1个月角膜散光度高于A组(P<0.05),术后3个月两组角膜散光度差异无统计学意义(P>0.05)。两组术后3个月角膜散光度与术前差异均无统计学意义(P>0.05)。A组术后1周、1个月视力高于B组(P<0.05),术后3个月两组间差异无统计学意义(P>0.5)。两组间并发症差异无统计学意义(P>0.05)。结论巩膜小切口超声乳化联合PMMA人工晶状体植入术具有视力恢复快,散光小等优点,适合在大范围扶贫白内障手术中应用。
Objective To evaluate the application efficacy of phacoemulsification combined with polymethylmethacrylate(PMMA) intraocular lens implantation through scleral small incision for cataract patients with charge free surgery for poverty alleviation. Methods The clinical data of 60 eyes of 60 patients with age-related cataracts from Jan.2018 to Aug.2018 were retrospectively analyzed. All cases were randomly divided into two groups. All cases enlarged the incisions to 5.5 mm after phacoemulsification and implanted PMMA intraocular lens.Group A, 30 eyes, received IOL implantation through the scleral incisions. Group B, 30 eyes, received IOL implantation through the transparent corneal incisions. The corneal astigmatism, visual acuity and complications were compared and analyzed between the two groups. Results The corneal astigmatism(CA)in group B were higher than that in group A (P<0.05) at 1 week and 1 month after surgery, and the difference was not significant in CA at 3 months after surgery between the two groups(P>0.05). The CA in group A and group B was not statistially significant between preoperation and 3 months after operation (P>0.05). The uncorrected visual acuity(UCVA)in group A were higher than that in group B at 1 week and 1 month after surgery (P<0.05), and the difference was not significant in UCVA between two groups at 3 months after surgery (P>0.05). There was no significant difference in complications between two groups(P>0.05). Conclusion The phacoemulsification combined with PMMA intraocular lens implantation through scleral incision for the treatment of cataract in poverty alleviation has good UCVA and lower CA.
