目的 探讨超声乳化治疗白内障合并超高度近视植入折叠式0和负度数人工晶状体的临床效果。
方法 对35例(49眼)白内障合并超高度近视的患者行超声乳化白内障吸除联合0和负度数IOL植入。观察术后视力、屈光状态及并发症等情况。随访时间3～15个月。
结果 全部植入人工晶状体，IOL度数为0～-8D，平均-1.96±-2.14D，未见严重并发症，术后视力满意。术后3月，裸眼视力：>0.3者16眼,占32.65 %；>0.5者7眼,占14.29 %；最佳矫正视力：0.3～0.5者23眼,占46.19%；>0.5者17眼,占34.69%；术后最佳矫正视力<0.05者3眼，占6.12%。患者术后均表现为低度近视性屈光不正。术后3月患者屈光度为—0.5～-2.75D，平均-1.38±0.65D；无过矫现象发生。术后实际屈光度与预期屈光度的差值为0.00～2.75D，平均1.45±0.66D。术后角膜水肿3眼（6.12%），术后一过性高眼压11眼（22.45%），术后复视1例（0.02%）。术后3个月无视网膜脱离者，亦未见黄斑囊样水肿、人工晶体移位等并发症。
结论 超声乳化白内障吸除植入折叠式0和负度数人工晶状体治疗白内障合并超高度近视临床效果良好，可以矫正屈光不正，促进恢复视力。

Objective To evaluate the clinical efects of phacoemulsification and implantation of 0 or negative-power posterior chamber intraocular lenses(IOL) in patients with extreme myopia and cataract
Methods Phacoemulstncation with 0 or negative power intraocular lens implantation were performed on 49 eyes of 35 patients with extremely high myopia. Postoperative visual acuity, refractive power and operative compltcations were observed．Follow-up period was 3~15 months after surgery．
Results Uncorrected visual acuity and corrected visual acuity were better in 0 or negative power intraocular lens patients . Corneal edema was found in 3 eyes.Temporal hypertention was found in 11 eyes. No eye was found with retinal detachment in 3 months to1 year after surgery, and no other complication．
Conclusion High myopia patients achieved visual improvement after phacoemulsificatton with 0 or negattve power intraocular lens implantation.
