Abstract：
OBJECTIVE: To determine the clinical outcomes in patients after type 1 Boston keratoprosthesis surgery and the significance of ultrasound biomicroscopy imaging for postoperative follow-up.
METHODS: This retrospective analysis included 20 eyes of 19 patients who underwent corneal transplantation with type 1 Boston keratoprosthesis between April 2014 and December 2021. Data on patient demographics, preoperative diagnosis, visual acuity, and postoperative clinical findings were analyzed.
RESULTS: Type 1 Boston keratoprosthesis implantation resulted in intermediate- and long-term positive outcomes. However, blindness and other serious complications such as glaucoma, retroprosthetic membrane formation, endophthalmitis, or retinal detachment also occurred. The use of ultrasound biomicroscopy imaging allowed for better evaluation of the back of the titanium plate, anterior segment structures, and the relationship of the prosthesis with surrounding tissues, which provided valuable postoperative information.
CONCLUSIONS: Regular lifetime monitoring and treatment are necessary in patients who undergo Boston type 1 keratoprosthesis implantation for high-risk corneal transplantation. ultrasound biomicroscopy imaging can be a valuable imaging technique for the evaluation of patients with Boston type 1 keratoprosthesis, providing important information on anterior segment anatomy and potential complications. Further studies and consensus on postoperative follow-up protocols are required to optimize the management of patients with Boston type 1 keratoprosthesis.

摘要：
目的：确定1型波士顿人工角膜手术后患者的临床结局以及超声生物显微镜成像对术后随访的意义。
方法：这项回顾性分析包括2014年4月至2021年12月期间接受1型波士顿人工角膜角膜移植的19例患者的20只眼。患者人口统计数据，术前诊断,视敏度,并对术后临床表现进行分析。
结果：1型波士顿人工角膜植入术产生了中期和长期的积极结果。然而,失明和其他严重并发症，如青光眼，假体后膜形成,眼内炎,或视网膜脱离也发生。使用超声生物显微镜成像可以更好地评估钛板的背面，前段结构，以及假体与周围组织的关系，这提供了有价值的术后信息。
结论：对于接受波士顿1型人工角膜植入术的高危角膜移植患者，需要定期进行终生监测和治疗。超声生物显微镜成像可以成为评估波士顿1型人工角膜患者的一种有价值的成像技术，提供关于眼前节解剖结构和潜在并发症的重要信息。需要进一步的研究和术后随访方案的共识，以优化波士顿1型人工角膜患者的管理。
