Amniotic membrane transplantation in corneal melting after anterior lamellar keratoplasty assisted by femtosecond laser in children.

摘要

To evaluate the efficacy of amniotic membrane transplantation in lamella melting after anterior lamellar keratoplasty (ALK) assisted by femtosecond laser in a pediatric patient.An 11-year-old girl with progressive keratoconus underwent ALK assisted by femtosecond laser on the right eye. The surgical procedure was performed under general anesthesia. The 60-KHz IntraLase femtosecond laser (Abbott Medical Optics) created both the donor (thickness 350 μm; diameter 8.1 mm; side cut 70°) and recipient (thickness 260 μm; diameter 8.0 mm; side cut 70°) lamellae. The recipient lamella was then gently removed and donor was fitted into place and sutured using 4 interrupted sutures added to a running suture in nylon 10-0. The surgery was uneventful. Two months after surgery, a lamella melting was observed. One month after topical steroid treatment, amniotic membrane transplantation was performed.When lamella melting was observed, the best-corrected visual acuity (BCVA) was 0.1 and 0.5 with foramen and no inflammatory reaction in the anterior chamber was reported. Eleven months after amniotic membrane transplantation, BCVA was 0.9 and no visual acuity increase was recorded with foramen.Our findings show that amniotic membrane transplantation could be considered in lamella melting after ALK assisted by femtosecond laser in children.
