Three different techniques are described for implanting posterior chamber lens implants during a combined extracapsular cataract extraction, posterior chamber lens implantation, and keratoplasty procedure. The implant can be placed immediately following cataract extraction, after which the cornea is replaced. If cortical remnants cannot be completely removed, the corneal transplant is sutured in place and a limbal incision made; the remaining remnants are then aspirated and a posterior chamber lens is implanted through the limbal incision. If no remnants remain, but the posterior chamber lens cannot be implanted due to positive vitreous pressure, the cornea is sewn into place with seven or eight interrupted sutures and the lens implanted through the remaining open quadrant, after which the corneal transplant procedure is completed.
本文描述了在白内障囊外摘除、后房型人工晶状体植入和角膜移植联合手术中植入后房型人工晶状体的三种不同技术。人工晶状体可在白内障摘除后立即植入,然后再置换角膜。如果皮质残留不能完全清除,先将角膜移植片缝合到位并做一个角膜缘切口;然后吸出剩余的残留皮质,通过角膜缘切口植入后房型人工晶状体。如果没有残留皮质,但由于玻璃体压力为正而无法植入后房型人工晶状体,则用七八针间断缝线将角膜缝合到位,通过剩余的开放象限植入晶状体,之后完成角膜移植手术。
