目的 :比较青光眼白内障分期手术和联合手术对患者视力眼压的影响。方法 :对 2 3例 (2 3眼 )施行联合手术加后房型人工晶体植入术 ;对 18例 (2 1眼 )首先行小梁切除术 ,术后 8个月～ 12年后行囊外摘除加后房型人工晶体植入术。比较术后矫正视力 ,角膜散光 ,眼压和滤过泡 ,结果采用spss软件行统计分析。结果 :术后二者矫正视力和角膜散光差别无显著性 (P >0 0 5 ) ;眼压 ,滤过泡差别成显著性 (P <0 0 5 )。结论 :青白联合手术术后滤过泡形成相对较差 ,眼压控制欠稳定 ,故虽早期视力和分期手术无差别 ,但长期不稳定的眼压对视功能将产生一定的影响
Objective: To compare the effect of glaucoma staging surgery and combined surgery on intraocular pressure in patients with glaucoma. Methods: Thirty-three cases (23 eyes) underwent combined surgery plus posterior chamber intraocular lens implantation. Eighteen patients (21 eyes) underwent trabeculectomy at first and then underwent extracapsular excision Plus posterior chamber intraocular lens implantation. The corrected visual acuity, corneal astigmatism, intraocular pressure and filtration bleb were compared. Results were analyzed by SPSS software. Results: There was no significant difference between corrected visual acuity and corneal astigmatism after operation (P> 0.05). The intraocular pressure and filtration bleb were significantly different (P <0.05). Conclusions: The formation of filtration bleb is relatively poor and the intraocular pressure control is not stable after operation. Therefore, although there is no difference in early visual acuity and staging, long-term unstable intraocular pressure will have a certain impact on visual function
