To present a modified Descemet's stripping automated endothelial keratoplasty (DSAEK) technique to avoid risks of endothelial cell loss related to the presence of a glaucoma tube in cases with shallow anterior chamber.
A 72-year-old patient with an only eye and corneal decompensation secondary to a Baerveldt tube was referred for keratoplasty. He was pseudophakic and had shallow anterior chamber. His best-corrected visual acuity was counting fingers close to face. He underwent a combined procedure with withdrawal and shortening of tube followed by a modified DSAEK employing a 7.5-mm donor graft in which a peripheral notch was performed to overlay the silicon tube.
No intraoperative or postoperative complications were noted. The endothelial cell count was 2000/mm after 15 months of the surgery. His best-corrected visual acuity remains 6/18 with a stable glaucoma.
This modified technique of DSAEK offers the benefits of endothelial transplant, and it could represent an option to reduce risks of corneal decompensation due to the presence of tubes in cases with shallow anterior chambers.
介绍一种改良的后弹力层剥除自动内皮角膜移植术(DSAEK)技术,以避免在前房浅的病例中因存在青光眼引流管而导致内皮细胞丢失的风险。
一名72岁单眼患者,因Baerveldt引流管导致角膜失代偿而被转诊接受角膜移植术。他是人工晶状体眼,前房浅。其最佳矫正视力为眼前数指。他接受了一项联合手术,包括引流管取出和缩短,随后进行改良的DSAEK,使用7.5毫米的供体移植物,在其中制作一个周边切口以覆盖硅胶管。
未观察到术中或术后并发症。术后15个月,内皮细胞计数为2000/mm²。其最佳矫正视力保持在6/18,青光眼病情稳定。
这种改良的DSAEK技术具有内皮移植的优点,对于前房浅且因引流管存在而有角膜失代偿风险的病例,它可能是一种选择。
