Abstract：
This study aims to analyze the pattern of follow-ups and the reasons for follow-up loss in keratoplasty cases in a tertiary eye care center.
This is a single-center retrospective cross-sectional study. During the study period, 165 eyes underwent corneal transplantation. The data on the demographic features of the recipients and the indications of keratoplasty, including visual acuity before and after surgery, duration of follow-up, and the condition of the graft at the last follow-up, were collected. The primary outcome was to determine the factors causing lost-to-follow-up (LTFU) among graft recipients. LTFU was defined when a patient failed to adhere to any of the following seven follow-up visits since the surgery: 4 ± 2 weeks, 3 ± 1 months, 6 ± 1 months, 12 ± 2 months, 18 ± 2 months, 24 ± 3 months, and 36 ± 6 months. The secondary outcome was to analyze the best-corrected visual acuity (BCVA) among patients available for the final follow-up.
The recipient follow-up rates at 6, 12, 18, 24, and 36 months were 68.5%, 57.6%, 47.9%, 42.4%, and 35.2%, respectively. Old age and distance to the center were significant factors for lost-to-follow-up. A failed graft as an indication for transplantation and those undergoing penetrating keratoplasty for optical purposes were significant factors for completing follow-up.
The inability to follow-up after corneal transplantation is a common challenge. Elderly patients and those living in remote areas must be prioritized for follow-ups.

摘要：
■本研究旨在分析三级眼部护理中心角膜移植术病例的随访模式和随访失败的原因。
■这是一项单中心回顾性横断面研究。在学习期间,165只眼行角膜移植术。受者的人口统计学特征和角膜移植术的适应症的数据，包括手术前后的视力，随访时间，最后一次随访时移植物的状况，被收集。主要结果是确定导致移植物接受者失访（LTFU）的因素。当患者自手术以来未能坚持以下7次随访中的任何一次时，定义为LTFU：4±2周，3±1个月，6±1个月，12±2个月，18±2个月，24±3个月，36±6个月。次要结果是分析可用于最终随访的患者的最佳矫正视力（BCVA）。
■受者在6、12、18、24和36个月的随访率为68.5％，57.6%,47.9%,42.4%,和35.2%，分别。年龄和距中心的距离是失去随访的重要因素。失败的移植物作为移植的指征以及为光学目的进行穿透性角膜移植术的移植物是完成随访的重要因素。
■角膜移植后无法进行随访是一个共同的挑战。必须优先考虑老年患者和偏远地区的患者进行随访。
