Superior peripheral iridectomy has been performed in 40 patients who have undergone silicone oil surgery for retinal detachment and who are aphakic. Only two developed raised intraocular pressure due to pupil block by liquid silicone and in each case the iridectomies seemed to be closed by proliferative membrane rather than the silicone meniscus. This type of iridectomy is particularly suitable in patients requiring intracapsular cataract extraction after previous vitrectomy and silicone oil surgery.
对40例接受过视网膜脱离硅油手术且无晶状体的患者实施了上方周边虹膜切除术。仅有2例因液态硅酮导致瞳孔阻滞而眼压升高，且在每例中，虹膜切除术似乎是被增殖膜而非硅酮半月形封闭。这种类型的虹膜切除术特别适用于先前已接受玻璃体切除术和硅油手术且需要行白内障囊内摘除术的患者。
