PURPOSE
To describe a surgical technique to repair Boston type 1 keratoprosthesis (KPro)-related corneal melts.
METHODS
Technique description and review of 3 representative cases.
RESULTS
After harvesting the buccal mucosa from the patient's inner lower lip, the exposed area of the KPro back plate is prepared for repair by adequate exposure and removal of necrotic tissue. The area is then covered with a lamellar patch of cornea secured in place with interrupted 10-0 nylon sutures, followed by a thin layer of buccal mucosa secured in place with interrupted 8-0 vicryl sutures.
CONCLUSIONS
This technique provides surgeons with a method to repair KPro-related corneal melts when there is a conjunctival deficiency.
目的
描述一种修复波士顿 1 型角膜性眼假肢（KPro）相关角膜溶解的手术技术。
方法
技术描述和 3 个代表性病例回顾。
结果
从患者的内下唇采集颊黏膜后，通过充分暴露和清除坏死组织来准备 KPro 后板的暴露区域进行修复。然后，用层状角膜片覆盖该区域，用间断的 10-0 尼龙缝线固定，然后用间断的 8-0 薇乔缝线固定一层薄薄的颊黏膜。
结论
当结膜缺损时，该技术为外科医生提供了一种修复 KPro 相关角膜溶解的方法。
