In the setting of penetrating keratoplasty for the rehabilitation of aphakic or pseudophakic bullous keratopathy, a posterior chamber intraocular lens is frequently implanted in the absence of capsular support. Some surgeons have advocated transscleral fixation over iris fixation of the intraocular lens. Problems faced during such a procedure, however, include the obstructed approach of the suture needle behind the iris, and the exposed or eroded knot of the polypropylene suture. To circumvent both problems, we propose an ab externo technique that takes advantage of the work of Duffey et al and avoids the use of partial thickness scleral flaps.
在穿透性角膜移植术用于无晶状体或人工晶状体性大泡性角膜病变康复的情况下，后房型人工晶状体常在无囊膜支撑时植入。一些外科医生主张人工晶状体经巩膜固定而非虹膜固定。然而，在此类手术过程中面临的问题包括缝线针在虹膜后方的进路受阻，以及聚丙烯缝线结外露或磨损。为规避这两个问题，我们提出一种外入路技术，该技术借鉴了达菲等人的方法，避免使用部分厚度的巩膜瓣。
