Negative intraocular lens implantation for super high myopic cataract

目的观察超声乳化白内障吸出负度数人工晶状体植入术治疗白内障合并超高度近视的临床效果。方法对66例97眼白内障合并超高度近视眼患者施行超声乳化白内障吸出联合负度数人工晶状体植入术,观察术后视力、屈光状态、眼前段情况和并发症。术后随访3～12个月。结果97眼均成功植入人工晶状体,视力都有不同程度的提高,术后3个月时矫正视力<0.1者9眼,0.1～0.4者52眼,>0.4者36眼;大部分患者残留低度的近视屈光状态;后囊膜混浊18眼;部分人工晶状体与后囊膜之间存在间隙,且后囊膜出现皱褶;无视网膜脱离和黄斑囊样水肿的发生。结论超声乳化白内障吸出联合植入负度数人工晶状体治疗白内障合并超高度近视眼,具有良好的有效性和安全性,同时预测性好,并发症少。

Objective To observe the clinical significance of negative intraocular lens implantation for super high myopic cataract. Methods Sixty-six super high myopic cataract cases （97 eyes） were performed phacoemulsification and negative intraocular lens implantation. Postoperative visual acuity, refractive status, anterior segment condition and complications were observed for 3 months to 1 year. Results Ninety-seven eyes were implanted intraocular lenses successfully. Postoperative visual acuity were improved. The corrected vision of 9 eyes were 〈 0.1 at 3 months after operation,52 eyes were between 0.1 and 0.4,36 eyes were 〉 0.4. Most patients kept residual low degree myopia. There was a gap between intraocular lens and folded posterior membrane in some cases. Posterior capsule opacification happened in 18 eyes,and no retinal detachment and cystoid macular edema happened. Conclusion Negative intraocular lens implantation for super high myopic cataract is effective, safe,predictable and has less complications.
