Abstract

Phototherapeutic keratectomy (PTK) combined with epikeratophakia (EP) using double lenticules through small-incision lenticule extraction (SMILE) after late recurrence was used in a patient with Reis-Bückler corneal dystrophy (RBCD) who underwent bilateral PTK 9.5 years previously. Opacity recurred at 4 years, with PTK + EP being performed using SMILE-derived lenticules, and at 5.5 years with an uncorrected visual acuity of 20/100 and disrupted counting fingers in the right and left eyes. PTK + EP in the right eye and PTK on the original lenticule in the left eye were performed. Manifest refraction was −4.25/−2.5 × 155 with a corrected distance visual acuity (CDVA) of 20/20 and −3.50/−0.75 × 140 with a CDVA of 20/20 in the right and left eyes, respectively, 2 months postoperatively. Lenticules remained transparent and well-attached to the corneal stroma, and the corneal epithelium reshaped successfully. The feasibility of repeated PTK + EP in patients with multiple RBCD recurrences was demonstrated, delaying the need for corneal transplantation.
光疗性角膜切除术联合双晶状体角膜外晶状体镜检治疗晚期复发性角膜营养不良
我们对9.5年前接受双侧角膜营养不良(RBCD)的reis - b克勒角膜营养不良(RBCD)患者进行了光治疗性角膜切除术(PTK)联合小切口角膜摘除术(SMILE)的晚期复发双晶状体角膜摘除术(EP)。术后4年复发,使用smile衍生的晶状体进行PTK + EP,术后5.5年未矫正视力为20/100,左右眼计数手指中断。右眼PTK + EP和左眼原晶状体PTK。术后2个月,明显屈光度为- 4.25/ - 2.5 × 155,矫正距离视力(CDVA)为20/20;明显屈光度为- 3.50/ - 0.75 × 140, CDVA为20/20。晶状体保持透明并与角膜基质良好附着,角膜上皮成功重塑。多次RBCD复发患者重复PTK + EP的可行性得到证实,延迟了角膜移植的需要。
