摘要

本篇收集111位病人，126眼，研究人工水晶體的紫外線過濾物質對黃斑部囊狀水腫發生率的影響。所有病人皆接受囊外晶體摘除及後房人工晶體植入，無併發症，後囊完整者。病人分兩組：一組接受“紫外線過濾型人工晶體”，另一組接受“非紫外線過濾型人工晶體”平均手術後3、4個月檢查。包括矯正後最佳視力，螢光血管攝影及眼底照像。結果，這兩組病人手術後的視力(P=0.7)及黃斑部囊狀水腫發生率（17.5%及11.1% P=0.53）皆無統計上的差異。且多數的Cystoid macula edema為subclinical type。

Cystoid macula edema is the most frequent cause of visual deterioration after cataract surgery. The cause is still unknown. Three possible mechanisms have been postulated: (Ⅰ) vitreous traction (Ⅱ) synthesis of prostaglandin (Ⅲ) phototoxicity from UV light of operating microscope or sunshine. The effect of UV-filtering IOL on the incidence of CME was studied in this report.
There were 111 patients (126 eyes) who received ECCE and posterior chamber intraocular lens implantation. They were divided into 2 groups: (Ⅰ) who received UV-filtering IOL and (Ⅱ) who received non-UV filtering IOL. The mean duration of post operative follow up was 3 to 4 months. All patients received a visual acuity examination a fluorescent angiogram, and fundophotography.
The result showed there were no differences in the post-operative visula acuity (P=0.7) or the incidence of angiographic CME (17.5% and 11.1% P=0.53) between these 2 groups. Most of the CME was of subclinical type and did not affect the visual outcome.
