BACKGROUND
Previously, penetrating keratoplasty has been used to treat corneal cap complications related to keratomileusis. We sought to develop a technique to avoid the unnecessary use of penetrating procedures for lamellar problems, that would be technically easier than standard lamellar keratoplasty--sutureless homoplastic lamellar keratoplasty.
METHODS
Five eyes with complications from automated lamellar keratoplasty underwent sutureless homoplastic lamellar keratoplasty utilizing an automated microkeratome and topical anesthesia.
RESULTS
Three of the five eyes had improved vision; two eyes with final visual acuities of 20/20 and 20/30. The two remaining eyes had poor host stromal beds and required penetrating keratoplasty. The mean follow-up time was 13 months (range 3 to 36 months). All lamellar grafts were clear and well-seated at the last postoperative examination.
CONCLUSION
Sutureless homoplastic lamellar keratoplasty is an alternative to penetrating keratoplasty in some eyes that have cap-related problems.
背景
此前，穿透性角膜移植术一直用于治疗与角膜磨镶术相关的角膜瓣并发症。我们试图开发一种技术，以避免对板层问题不必要地采用穿透性手术，该技术在技术上要比标准板层角膜移植术（无缝合同种异体板层角膜移植术）更简单。
方法
对5只因自动板层角膜成形术出现并发症的眼睛，使用自动微型角膜刀和表面麻醉进行无缝合同种异体板层角膜移植术。
结果
5只眼中有3只视力得到改善；2只眼最终视力达到20/20和20/30。其余2只眼的植床基质较差，需要进行穿透性角膜移植术。平均随访时间为13个月（范围3至36个月）。在最后一次术后检查时，所有板层移植片均透明且贴合良好。
结论
对于一些存在角膜瓣相关问题的眼睛，无缝合同种异体板层角膜移植术是穿透性角膜移植术的一种替代方法。
