目的:探讨表面麻醉下行小切口非超声乳化白内障摘除及人工晶状体植入术的安全性及有效性。方法:对79例86眼白内障患者在表面麻醉下行小切口非超声乳化白内障摘除及人工晶状体植入术并观察其麻醉效果及术后视力。结果:其中64例71眼无疼痛,15例15眼胀痛,术中追加一次表面麻醉。平均手术时间为18min,术后1d及1wk视力≥0.5者分别占83%和92%。结论:表面麻醉小切口非超声乳化白内障摘除及人工晶状体植入术具有操作简单,手术时间短,术后视力恢复快且稳定,手术成本低,适合我国国情,有利于规模化手术。

AIM:To investigate the safety and efficaty of topical anesthesia in non-phacoemutsification cataract extraction and introcular lens (IOL) implantation using small incision. ·METHODS:Under topical anesthesia,small incision non-phacoemulsification cataract extraction and IOL implantation were done in 79 patients 86 eyes,and the effectiveness of topical anesthesia and postoperative visual acuity were surveyed. ·RESULTS:Sixty-four patients 71 eyes complained no pain. 15 patients 15 eyes complained distending pain,and another topical anesthetic was given during operation.The mean duration of the operation was about 18 minutes. The vision ≥0.5 was 83% (at first postoperative day)and 92%(at 1 week postoperatively) respectively. ·CONCLUSION:Small incision non-phacoemulsification cataract extraction and IOL implantation under topical anesthesia is simple and spends little time. The recovery of eyesight is quick and stable. The cost of operation is very cheap. This operation has many advantages in our country.
