To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma
Femtosecond laser (IntraLase; IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection.
In Case 1, the graft was clear and compact without interface haze, Orbscan showed smooth and regular corneal surface, specular microscopy was unremarkable without sign of corneal endothelial damage, and Optical coherence tomography showed uniform graft well attached to recipient stroma with minimal interface reflection at 2 months postoperation. In Case 2, the graft was clear and compact with minimal interface haze at 1 month postoperation. Femtosecond laser-assisted small incision DLEK was safe and technically feasible in our cases; however, further evaluation is required to determine long-term effects.
报告两例采用飞秒激光辅助小切口深板层内皮角膜移植术（DLEK）治疗富克斯营养不良和青光眼导致角膜内皮失代偿患者的病例。
使用重复频率为15kHz的飞秒激光（IntraLase；IntraLase公司，加利福尼亚州欧文市）进行直径9.5mm、厚度400微米的供体角膜板层剖切。
病例1中，移植片清晰且紧密，无界面混浊，Orbscan显示角膜表面光滑规则，角膜内皮镜检查无异常，无角膜内皮损伤迹象，光学相干断层扫描显示术后2个月移植片均匀贴附于受体基质，界面反射最小。病例2中，术后1个月移植片清晰紧密，界面混浊轻微。在我们的病例中，飞秒激光辅助小切口DLEK是安全且技术上可行的；然而，需要进一步评估以确定其长期效果。
