RESUMEN
AlM:To evaluate the effect of intralamellar cryolysis of cornea with amniotic membrane transplantation on painful bullous keratopathy ( PBK) .?METHODS: Randomly selected 156 cases ( 156 eyes ) with PBK who underwent surgery of intralamellar cryolysis of cornea with amniotic membrane transplantation. Followed up with 2 ~ 3mo, the symptoms of eye pain, corneal epithelial blisters, foreign body sensation and postoperative complications were observed.?RESULTS:Pain symptoms disappeared in all patients, and corneal epithelial blisters disappeared in 130 cases (83. 3%). All agonizing pain symptoms disappeared, but patients had occasional foreign - body sensation, occasional corneal epithelial blisters in 24 cases ( 15. 4%) . Two weeks after surgery, corneal stroma dissolved, 2 cases ( 1. 3%) of them were cured by conjunctival flap cover.?CONCLUSlON:The operation of intralamellar cryolysis of cornea with amniotic membrane transplantation can relieve the pain in 98. 7% of PBK patients and simple therapy for treating PBK.
