Observation and comparison of two kinds of astigmatism correction intraocular lens after operation and middle and long term rotation stability

目的分析比较两种散光矫正型人工晶体在治疗白内障合并散光患者的术后效果及中长期旋转稳定性。方法回顾2015年1月~2016年7月期间在我院手术的57例(66眼)白内障合并角膜散光的患者,根据植入的人工晶体的类型进行分组,其中植入Alcon公司散光人工晶体(30例35眼),植入AMO公司散光人工晶体(27例31眼),术后随访半年到1年,比较术前术后裸眼视力、矫正视力、术后残余散光度、术后一天及半年后人工晶体旋转的度数,并比较两者的术后效果及旋转稳定性。结果两种散光矫正型人工晶体半年后散光矫正效果良好,而且旋转稳定性均表现优异,Alcon组术后平均裸眼视力为(0.88±0.17),AMO组术后平均裸眼视力为(0.86±0.16);Alcon组术后平均残留散光度为(0.42±0.23)D,AMO组术后平均残留散光度为(0.44±0.21)D;Alcon组97.15%的患者旋转在5°以下,2.85%的患者(一例)旋转在5°~10°之间,平均旋转度数为(2.10±1.42)°;AMO组96.78%的患者旋转在5°以下,3.22%的患者(一例)旋转在5°~10°之间,平均旋转度数为(2.14±1.26)°,且两组的术后平均裸眼视力,残留散光度及整体旋转稳定性差异均无统计学意义(P>0.05)。结论两种散光矫正型人工晶体治疗白内障合并散光的患者矫正效果良好,旋转稳定性佳,而且两者的手术矫正效果及旋转稳定性无明显差异。

Objective To analyze the postoperative effects and middle and long-term rotational stability of two kinds of astigmatism correction intraocular lens in the treatment of cataract with astigmatism.Methods Fifty-seven patients(66 eyes)with cataract and corneal astigmatism who underwent surgery in our hospital from January 2015 to July 2016 were divided into groups according to the type of intraocular lens implantation.Alcon astigmatism intraocular lens was implanted in 30 cases(35 eyes).AMO astigmatism intraocular lens was implanted in 27 cases(31 eyes).After a follow-up of six months to 1 years,the visual acuity,corrected visual acuity,residual astigmatism after operation,and the degree of rotation of intraocular lens after one and half a year after operation were compared.The postoperative effects and rotational stability of the two groups were compared.Results Two astigmatism corrected intraocular lens had good effect on astigmatism correction after six months,and the rotation stability was excellent.The mean visual acuity of group Alcon was(0.88±0.17)after operation,and the average visual acuity of group AMO was(0.86±0.16)after operation.The average residual astigmatism in group Alcon was(0.42±0.23)D,and the average residual astigmatism in group AMO was(0.44±0.21)D after operation.In group Alcon,97.15%of patients were below 5 degree of rotation,2.85%of patients rotated at 5-10 degrees,and the average rotational degree was(2.10±1.42)degrees.In group AMO,96.78%of patients were below 5 degree of rotation,3.22%of patients rotated at 5-10 degrees,and the average rotational degree was(2.14±1.26)degrees.There was no significant difference in postoperative mean visual acuity,residual astigmatism and overall rotation stability between the two groups.Conclusion Two kinds of astigmatism correction intraocular lens have good correction effect and good rotation stability in the treatment of cataract with astigmatism,and there is no significant difference in the effect of surgical correction and rotation stability.
