A 31-year old female underwent lamellar keratoplasty for the treatment of bilateral primary familial amyloidosis of the cornea in 1983 (OS), 1986 (OD), and 1989 (OS). The lesions recurred bilaterally and visual acuity in 1992 was 20/400 in each eye. After debridement of essentially all corneal epithelium, the entire cornea of the left eye was treated with excimer laser phototherapeutic keratectomy (PTK). One month postoperatively, visual acuity was 20/50 and the corneal surface appeared smooth and clear with no evidence of recurrence. Four months postoperatively, the patient continued to be free of recurrence.
一名31岁女性于1983年（左眼）、1986年（右眼）和1989年（左眼）接受了板层角膜移植术，以治疗双侧原发性家族性角膜淀粉样变性。病变双侧复发，1992年时每只眼睛的视力均为20/400。在基本去除所有角膜上皮后，左眼整个角膜接受了准分子激光光治疗性角膜切削术（PTK）。术后1个月，视力为20/50，角膜表面光滑、清晰，无复发迹象。术后4个月，患者仍未复发。
