目的 :评价 474眼高度近视合并白内障行超声乳化白内障摘除及后房型人工晶体植入术的疗效。方法 :对 412例 ( 4 74眼 )高度近视合并白内障行反眉弓巩膜隧道超声乳化吸除 ,3 5mm切口植入折叠式人工晶体 ,5 5mm切口植入PMMA硬性人工晶体。平均眼轴长 2 8 12± 2 5 3mm ( 2 7-33 5 2mm ) ,其中 2 7～ 30mm者 2 6 9眼 ,>30mm者 2 0 5眼。随访 6月 -2年 ,观察超声乳化能量、时间、术后视力和并发症。结果 :眼轴 2 7～ 30mm组术后 3月视力≥ 0 5者 2 39眼占 88 85 % ,后囊破裂 19眼 ( 7% ) ,悬韧带断裂 2眼 ( 0 74% )。眼轴≥30mm组视力≥ 0 5者 10 3眼占 5 0 2 4% ,后囊破裂 11眼 ( 5 37% ) ,悬韧带断裂 2眼 ( 0 98% ) ,角膜失代偿 2眼 ( 0 98% ) ,视网膜脱离 5眼 ( 2 44% )。术后 3月两组视力差异显著。结论 :高度近视白内障超声乳化及后房型人工晶体植入术能改善患者的视力 ,但眼轴 >
Objective:To evaluate the therapeutic effect of phacoemulsification and posterior chamber intraocular lens(IOL)implantation in 474 high myopia. Methods:Phacoemulsification and IOL implantation was performed on 474 eyes of 412 patients with high myopia and cataracts through an against frown shape scleral tunnel incision.A foldable IOL was inserted through a 3 5mm incision and a PMMA IOL inserted through a 5 5mm incision.The mean axial length was 28 12±2 53mm(27-33 52mm).The phaco energy and duration were observed.Postoperative visual acuity and complications were assessed after 6 months to 2 years following up. Results:239 eyes′ visual acuity(88 85%)was better than 0 5 in 27～30mm axial length group while that of 103 eyes(50 24%)in ≥30mm axial length group.The common complications were posterior capsule ruptured and suspensory ligaments broken.In the latter group,2 eyes(0 98%)had uncompensated cornea and 5 eyes(2 44%)had detached retina.Difference of visual acuity between the two groups was statistically significant at 3 month postoperatively. Conclusions:Visual acuity could be improved for high myopia and cataract patients with phacoemulsification and posterior chamber IOL implantation.While the recovery for eyes with axial lengths over 30mm was less satisfactory.
