目的:观察巩膜隧道切口超声乳化吸出及硬质人工晶状体植入术治疗白内障的临床效果。方法:对256例295眼白内障实行超声乳化吸除,同时通过5.5mm切口植入PMMA硬性人工晶状体。观察术中、术后并发症及手术效果。术后随访3～6mo。结果:术后3mo,视力<0.1者4眼,0.1～0.4者67眼,0.5～1.0者212眼,>1.0者12眼。术中并发症:后囊膜破裂3眼;晶状体脱位2眼。术后并发症:角膜水肿29眼;前房积血1眼。结论:巩膜隧道切口适合于超声乳化吸出及硬质人工晶状体植入术,具有并发症少及视力恢复快等优点。

·AIM:To study the effect on cataract treated by phacoemulsification with scleral tunnel incision and implantation of the PMMA posterior chamber lens.·METHODS:There were 256 cases 295 eyes with cataract who underwent corneal tunnel incision and phacoe-mulsification.·RESULTS:There were 224 eyes(75.9%)whose vision exceeded 0.5 three months postoperatively.Retinal detachment and macular vesicular edema did not appear.·CONCLUSION:Phacoemulsification with scleral tunnel incison has many merits such as small incision and low astigmia.It can prevent complications and recover the visual function quickly.·
