To analyze the visual outcome of Boston keratoprosthesis for keratopathy in silicone oil-filled eyes.
Retrospective chart review of patients with silicone oil-induced keratopathy undergoing Boston keratoprosthesis between January 2008 and June 2010 was performed. Patients received Boston keratoprosthesis as the primary procedure or after a failed penetrating keratoplasty because of silicone oil-induced keratopathy after assessing possible visual potential. Silicone oil had to be retained in all eyes because of persistent ocular hypotony.
Of the 8 eyes that underwent surgery, anatomic retention and visual improvement were noted in 7 eyes (87.5%). The visual acuity improved to 20/200 or better in 6 eyes (66.67%). Repeated corneal melt necessitated the removal of the prosthesis with corneal transplant in 1 eye. Membranectomy was performed twice for retroprosthetic membrane in 1 eye.
Boston keratoprosthesis seems to be a viable option for visual rehabilitation in postvitrectomized eyes with a decrease in vision due to retained silicone oil-induced keratopathy.
分析硅油填充眼行 Boston 角膜移植术治疗角膜病变的视力结果。
回顾性分析 2008 年 1 月至 2010 年 6 月期间因硅油性角膜病变行 Boston 角膜移植术的硅油填充眼患者的临床资料。所有患者均因硅油性角膜病变行穿透性角膜移植术失败，且由于持续性低眼压需保留硅油而接受 Boston 角膜移植术。评估患者的潜在视力后，将 Boston 角膜移植术作为首选治疗方案或挽救性治疗方案。
8 只眼中，7 只眼（87.5%）获得了良好的解剖学效果和视力改善。6 只眼（66.67%）视力提高至 20/200 或更好。1 只眼因反复发生角膜融解而需取出假体行角膜移植术。1 只眼因后弹力层下膜需行 2 次膜切除术。
Boston 角膜移植术似乎是治疗因硅油性角膜病变导致视力下降的玻璃体切割术后眼的一种可行方法。
