目的观察同轴微切口白内障超声乳化吸除联合微切口IOL植入术后的视觉质量和IOL偏心及倾斜,评估微切口IOL的稳定性.方法回顾性系列病例研究.选择在中国医科大学附属第四医院眼科行1.8 mm同轴微切口超声乳化白内障吸除联合Akreos MI60 IOL植入的患者20例(20眼).观察术后3个月、6个月的UCVA、BCVA、像差、散射光、IOL倾斜及偏心等.采用连续测量的方差分析对数据进行处理.结果术后3个月及6个月,患者UCVA、BCVA与术前相比差异均有统计学意义(P＜0.05),20例患者术前散射光为2.56±0.28,与术后3个月及术后6个月矫正后比较差异均有统计学意义(F=0.532,P＜0.05).术后1周、3个月和6个月,IOL的偏心量差异无统计学意义(F=2.066,P＞0.05),IOL的倾斜度变化无统计学意义(F=2.734,P＞0.05).术后1周、3个月和6个月平均高阶像差值变化无统计学意义(F=0.692,P＞0.05).结论 1.8 mm同轴微切口超声乳化白内障吸除联合Akreos MI60 IOL植入在手术后具有良好的稳定性,患者可以获稳定的UCVA.

Objective To observe the visual quality of microincision phacoemulsification cataract surgery and evaluate the stability of microincision intraocular lens by evaluating the IOL tilt and decentration.Methods A retrospective study was carried out on 20 patients.The patients received 1.8 mm microincision phacoemulsification cataract surgery with Akreos MI60 implantation.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),ocular aberration,staylights,the tilt and decentration of the IOLs were analyzed at 3 months,6 months postoperation.Statistical analysis was carried out using the repeated-measured analysis of variance (ANOVA).Results The UCVA and BCVA were significantly improved at 3 months and 6 months after the operation (P＜0.05).There was significant difference of staylights at 3 months and 6 months postoperation comparing with preoperation results.No significant difference was found for the average tilt and decentration of IOL of 1 week,3 months,and 6 months after the surgery (P＞0.05).No significant difference was found for the higher-order aberration of 1 week,3 months,and 6 months postoperatively (P＞0.05).Conclusion The 1.8 mm microincision phacoemulsification with Akreos MI60 implantation can provide good lens stability and stable visual acuity for the patients.
