Femtosecond laser–assisted intrastromal corneal lenticule implantation for treatment of advanced keratoconus in a child’s eye

摘要： We present a case of a 12-year-old male patient who received a femtosecond laser–assisted intrastromal implantation of a donor lenticule for the treatment of advanced keratoconus. Initially, the uncorrected distance visual acuity (UDVA) in the left eye was counting fingers (CF) and cycloplegic refraction was (cid:1)18.50 (cid:1)4.50 (cid:3) 85 Z 20/400. Preoperative corneal topography demonstrated a curvature of 65.90 (cid:3) 62/57.17 (cid:3) 152. Twelve months after lenticule implantation, the cornea was completely clear and the thickness changed from 245 mm to 639 mm. The UDVA was CF at 2 m and refraction was (cid:1)12.25 (cid:1)2.50 (cid:3) 180 Z 20/30, whereas topography demonstrated a curvature of 61.44 (cid:3) 52/59.28 (cid:3) 142. The results showed that the procedure was successful in thickening and flattening the cornea. It is expected that penetrating or deep anterior lamellar keratoplasty, if required, could be postponed to a more suitable age.
