持续戴亲水性接触镜以矫正无晶体眼和近视眼的视力,目前认为是安全而有效的。这种接触镜中心部厚度及含水量可以供应角膜最低的代谢需要,同时严重的并发症发生率也低。本文对经选择的15例无晶体眼穿透角膜移植者、穿透角膜移植与白内障同时摘除者或角膜移植后作晶体摘出者,分别戴不同的亲水性接触镜。接触镜曲率半径为7.7—8.9mm,直径为13.5—14.5mm,最常用的曲率半径为8.9mm,直径为14.5mm。选择接触镜的曲率半径比角膜曲率半径大0.2~0.5mm,直径比角膜直径大1~1.5mm。于术后3—43个月开始戴镜。15例中12例滴皮质类固醇,每日1~2次,可抑制角膜新生血管。戴镜期间不使用预防性抗生素滴剂。带镜后随访5—24个月,3眼移植片出现新生血管,
Continued wear hydrophilic contact lenses to correct the vision of aphakia and myopia, is currently considered safe and effective. The thickness and moisture content of the center of the contact lens can supply the lowest metabolic needs of the cornea, while the incidence of serious complications is also low. In this paper, the selected 15 cases of aphakic corneal transplanted corneal transplants, corneal transplants and cataract patients with simultaneous removal or after corneal transplantation for crystal removal, were wearing different hydrophilic contact lenses. The contact lens has a radius of curvature of 7.7-8.9 mm, a diameter of 13.5-14.5 mm, the most commonly used radius of curvature of 8.9 mm and a diameter of 14.5 mm. Select the contact lens curvature radius greater than the corneal curvature 0.2 ~ 0.5mm, the diameter larger than the corneal diameter of 1 ~ 1.5mm. Wearing glasses after 3-43 months. Of the 15 cases, 12 cases drip corticosteroids, 1 or 2 times a day, can inhibit corneal neovascularization. Do not use prophylactic antibiotic drops when wearing glasses. Follow-up with a mirror after 5-24 months, 3 eyes appeared new blood vessels graft,
