目的:研究超声乳化联合植入负低度数后房型人工晶状体治疗高度近视眼合并白内障的临床效果。方法:对试验组80例100眼高度近视并发白内障实行巩膜隧道切口超声乳化吸除,同时通过5.5mm切口植入PMMA硬性人工晶状体。其中男45例56眼,女35例44眼,年龄44～76(平均61)岁;眼轴长为27.00～35.42(平均30.55)mm。取同期来我院治疗的94例100眼正常眼轴老年性白内障患者作为对照组。观察术中、术后并发症及手术效果。术后随访3～12mo。结果:试验组术后3mo矫正视力≥0.5者为51眼(51.0%),0.1～者43眼(43.0%),<0.1者6眼(6.0%)。术中并发症:后囊膜破裂2眼;晶状体脱位2眼。术后并发症:角膜水肿9眼;视网膜脱离1眼;后发性白内障2眼。对照组术中并发症:晶状体脱位1眼。术后并发症:角膜水肿4眼;后发性白内障2眼。结论:巩膜隧道切口超声乳化联合硬质后房型人工晶状体植入术治疗高度近视并发白内障,具有视力恢复快、屈光状态稳定等优点,是安全有效的方法。

AIM:To study the effect on high myopia accompanied with cataract treated by phacoemulsification and implantation of the low dimensionality posterior chamber intraocular lens(IOL).METHODS:Eighty cases 100 eyes of high myopia accompanied with cataract whose mean axis oculi was 30.55mm received phacoemulsification and IOL implantation.We used sclera tunnel incision and phacoemulsification debulk.Preoperative axial length,preoperative visual acuity and postoperative visual acuity were recorded.Intraoperative and postoperative complications were observed.The follow-up time was from 3 to 12 months.RESULTS:There were 51 eyes(51.0%)whose best-corrected visual acuity exceeded 0.5 three months postoperatively.The operative complications were the rupture of posterior capsule 2 eyes,dislocation of lens 2 eyes.The postoperative complications were corneal endothelial edema 9 eyes,after cataract 2 eyes,retinal detachment 1 eye.CONCLUSION:Phacoemulsification has many merits such as small incision and low astigmia.Phacoemulsification and implantation of the low dimensionality posterior chamber IOL used to treat high myopia accompanied with cataract can prevent complication and recover the visual function.
