目的:探讨高度近视合并白内障超声乳化手术的技巧和术后低视力原因,方法:对85例(106眼)眼轴>26mm的高度近视白内障患者施行超声乳化术。结果:术后3个月矫正视力<1.1者13眼占12.3％;≥0.5者46眼占43.4％。矫正视力<0.1者,26-28mm组占5.4％,28-30mm组占12.9％,30-32mm组占16.0％,>32mm组占23.1％。并发症:后囊破裂1例,角膜水肿4例,后囊膜混浊3例,前囊收缩综合症1例。未见视网膜脱离和黄斑囊样水肿。结论:高度近视合并白内障超声乳化手术技术要求比较高,如能熟练掌握其技术,术后可取得较好视力。高度近视白内障术后视力与眼轴长度有关,同时也与高度近视眼底病变的部位有关。
Objective: To explore the technique and the reason of low vision after phacoemulsification with high myopia and cataract.Methods: 85 cases (106 eyes) of high myopia cataract patients with axial> 26mm were performed phacoemulsification. Results: Three months after operation, corrected visual acuity was less than 1.1, accounting for 12.3% in 13 eyes and 46 eyes in ≥0.5 eyes, accounting for 43.4%. The corrected visual acuity was less than 0.1, accounting for 5.4% in 26-28mm group, 12.9% in 28-30mm group, 16.0% in 30-32mm group and 23.1% in> 32mm group. Complications: 1 case of posterior capsule rupture, 4 cases of corneal edema, 3 cases of posterior capsular opacity, 1 case of anterior capsule contraction syndrome. No retinal detachment and cystoid macular edema. Conclusion: High myopia with cataract phacoemulsification technique is relatively high, if skilled mastery of technology, can obtain better vision after surgery. High myopia visual acuity after cataract surgery and axial length, but also with high myopia lesions at the site.
