ABSTRACT
Objective: To discuss the clinical efficacy of bandage contact lens (BCL)in pterygium excision combined with conjunctival transplantation for the older adults,and to explain its advantages.Methods:The clinical materials of 70 older patients (70 eyes ) who underwent the pterygium excision combined with conjunctival transplantation were retrospectively analyzed.They were divided into two groups according to the postoperative treatment.In the observation group,35 cases (35 eyes)wore BCL after operation.In control group,35 cases (35 eyes)were covered with normal eye pad.The scores of blurred vision,photophobia,foreign body sensation, lacrimation,eye-soreness,corneal fluorescence stain (FSC)and epithelial defect areas were observed at 1,3,7 and 10 d afer operation.Results:The scores of blurred vision,photophobia,foreign body sensation,lacrimation,eye-soreness of the patients in observation group were significantly lower than those in control group at 1,3,and 7 d afer operation (P 0.05).No complications of infection and implant healing badness were observed in all patients.Conclusion:BCL can significantly reduce the irritations after pterygium excision combined with conjunctival transplantation for the older adults and promote the healing of the corneal epithelium.
ABSTRACT
Objective To evaluate the therapeutic effect of pedical conjunctival flap transposition on refractory corneal ulcer. Methods The data of 56 eyes of 56 patients with refractory corneal ulcer who underwent pedical conjuctival transposition in a tertiary eye unit in China from June 2005 to June 2009 were retrospectively analyzed. There were 36 infective corneal ulcers, 9 keratoplasty graft ulcers, 4 traumatic ulcers, and 7 chemical burn ulcers. All patients were treated with focal debridement and pedical conjuctival flap transposition. Results Forty-seven out of 56 (83.9%) were cured after one surgery, and 5 (8.9%) had conjunctival flap retraction, among which 3 underwent the second surgery and 2 had the third surgery to completely heal. Four patients (7.2%) turned to lamellar keratoplasty because of fungal corneal ulcer relapse. Ulcer in 52 patients healed and the globe preserved. They had different levels of vision improvement. Conclusion Pedical conjunctival flap transposition is effective for refractory corneal ulcer.
