Cataract surgery after penetratingkeratoplasty (PKP) is often challenging due to changes in the integrity of the cornea caused by PKP. For example, corneal endothelial cell (CEC) loss and corneal edema commonly occur after traditional phacoemulsification cataract surgery in patients that previously had successful PKP. Recent studies have reported that femtosecond laser-assisted cataract surgery (FLACS) significantly reduces the need for ultrasound energy minimizing mechanical damage to the cornea and results in a reduction of CEC loss and corneal edema.
We report a case in which FLACS was used in a patient with previous PKP.
This case supports the suggestion that the use of the femtosecond laser improves the surgical outcome of cataract surgery after PKP. This improvement may be result of the precise incision, controlled capsulorhexis, and reduced lens fragmentation experienced with the femtosecond laser which helps to reduce potential complications of cataract surgery after PKP.
穿透性角膜移植术（PKP）后进行白内障手术往往具有挑战性，因为PKP会导致角膜完整性发生变化。例如，在先前成功进行PKP的患者中，传统超声乳化白内障手术后常出现角膜内皮细胞（CEC）丢失和角膜水肿。最近的研究报告称，飞秒激光辅助白内障手术（FLACS）显著减少了对超声能量的需求，最大限度地减少了对角膜的机械损伤，并减少了CEC丢失和角膜水肿。
我们报告了一例在先前接受过PKP的患者中使用FLACS的病例。
该病例支持以下观点，即飞秒激光的使用改善了PKP后白内障手术的手术效果。这种改善可能是由于飞秒激光具有精确的切口、可控的撕囊以及减少的晶状体破碎，这有助于减少PKP后白内障手术的潜在并发症。
