后巩膜葡萄肿对高度近视白内障患者术后人工晶状体稳定性的影响

Impact of posterior scleral staphyloma on the postoperative stability of artificial lenses in highly myopic patients with cataracts

目的探究后巩膜葡萄肿对高度近视白内障患者术后人工晶状体稳定性的影响。方法57例(63眼)行白内障超声乳化联合人工晶状体植入术的白内障伴高度近视患者根据是否存在后巩膜葡萄肿分研究组(26例共28眼,合并后巩膜葡萄肿)和对照组(31例共35眼,单纯白内障伴高度近视)。对比两组术前眼轴,术后3个月眼轴、中轴区晶状体后囊膜至视网膜距离、前房深度、角膜曲率、最佳矫正视力(BCAV)、平均绝对屈光误差(MAE)、人工晶状体囊袋偏心量及倾斜角。结果研究组术前及术后3个月眼轴长度、术后3个月BCAV、裸眼视力数值(logMAR)、MAE、水平及垂直方向的倾斜角、前房深度均高于对照组(P<0.01或0.05)。结论高度近视合并巩膜葡萄肿患者行白内障手术时应关注人工晶状体的稳定性。

ObjectiveTo explore the impact of posterior scleral staphyloma on the postoperative stability of artificial lenses in highly myopic patients with cataracts.Methods A total of 57 cases(63 eyes)of highly myopic patients with cataracts who underwent phacoemulsification combined with artificial intraocular lens implantation were divided into two groups based on whether there was posterior scleral staphyloma:26 cases(28 eyes)with concurrent posterior scleral staphyloma were included in the Study Group,and 31 cases(35 eyes)with isolated cataract accompanied by high myopia were included in the Control Group.The preoperative axis oculi,postoperative axis oculi at 3 months,distance from the posterior capsule of the crystalline lens to the retina in the central zone,anterior chamber depth,corneal curvature,best-corrected visual acuity(BCVA),mean absolute refractive error(MAE),eccentricity of the artificial intraocular lens bag,and tilt angle were compared between the two groups.Results The Study Group had the axis oculi before and at 3 months after operation,and BCVA,logMAR,MAE,horizontal and vertical tilt angle and anterior chamber depth at 3 months after operation all higher than the Control Group(P<0.01 or 0.05).Conclusion Special attention should be paid to the stability of the artificial intraocular lens during cataract surgery in patients with high myopia combined with posterior scleral staphyloma.
