目的:探讨表面麻醉联合球结膜下麻醉经颞侧施行小切口白内障囊外摘出人工晶状体植入手术效果。方法:对32例40眼青光眼小梁切除术后的白内障患者用倍诺喜表面麻醉联合球结膜下注射20g/L利多卡因麻醉,行改良小切口白内障囊外摘出联合后房型人工晶状体植入术,分析手术的麻醉效果及手术后的治疗效果。结果:全部患眼均能达到理想的麻醉镇痛效果,顺利完成手术,术后视力<0.1者5眼(12.5%),视力0.1～0.4者9眼(22.5%),术后视力≥0.5者26眼(65.0%),所有患眼术后视力与术前比较均有提高。结论:表面麻醉联合球结膜下麻醉经颞侧施行小切口白内障囊外摘出人工晶状体植入手术,是治疗青光眼小梁切除术后白内障有效的手术方式,手术操作简便,不需要昂贵的手术设备,适用于基层医院开展。

AIM:To investigate clinical effect of temporal small incision extracapsular cataract extraction (ECCE) and intraocular lens implantation with topical and subcon-junctival anesthesia. ·METHODS:Totally 32 patients 40 eyes with cataract after trabeculectomy underwent the small incision ECCE and intraocular lens implantation surgery by topical anesthesia and subconjunctival anesthesia (20g/L lidocaine),the anesthetic and therapeutic effect of surgery were evaluated. ·RESULTS:All patients had the desired analgesic effect and successful surgery procedure,postoperative visual acuity <0.1 in 5 eyes (12.5%) ,,visual acuity from 0.1 to 0.4 in 9 eyes (22.5%),visual acuity ≥ 0.5 in 26 eyes (65.0%); All the visual acuity were improved. ·CONCLUSION:The temporal small incision ECCE and intraocular lens implantation surgery by topical anesthesia combined with subconjunctival anesthesia is a simple and effective surgery for the patients with cataract after trabeculectomy surgery,especially in primary hospitals with cheap surgical equipment.
