OBJECTIVE
To report the clinical findings and results of a patient who underwent deep anterior lamellar keratoplasty (DALK) combined with phacoemulsification.
METHODS
Retrospective analysis of a case that underwent unsuccessful DALK surgery with no visual gain due to striations on the posterior surface of the donor, permanent interface irregularity, and scarring.
RESULTS
Two years after the first DALK surgery, a repeated DALK was performed in combination with phacoemulsification of the cataract that developed during this period. The graft was clear with no signs of rejection or endothelial decompensation, and corrected distance visual acuity was 6/10 in the postoperative last visit, one year after the surgery.
CONCLUSIONS
Combining the DALK technique with phacoemulsification in patients with coexisting cataracts may help to achieve a good visual outcome and long-term graft survival. Even after an unsuccessful DALK experience, insisting on preserving the patient's own endothelium resulted in successful vision restoration with no imposition of further risks for graft survival.
目的
报告一名接受深板层角膜移植术（DALK）联合超声乳化术患者的临床发现及结果。
方法
对一例DALK手术失败的病例进行回顾性分析，该患者因供体后表面条纹、永久性界面不规则及瘢痕形成而未获得视力改善。
结果
首次DALK手术后两年，再次进行DALK手术并联合对在此期间形成的白内障进行超声乳化术。移植片清晰，无排斥或内皮失代偿迹象，术后最后一次随访时（手术一年后）矫正远视力为6/10。
结论
对于合并白内障的患者，将DALK技术与超声乳化术相结合可能有助于获得良好的视力结果及移植片的长期存活。即使经历了失败的DALK手术，坚持保留患者自身内皮仍成功恢复了视力，且未给移植片存活带来额外风险。
