Application of bandage contact lens in pterygium excision combined with conjunctival transplantation in older adults and evaluation on its efficacy / 吉林大学学报(医学版)

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.
