Clinical effect of combined bandage contact lenses and artificial tears on corneal epithelial injury due to correction of blepharoptosis

Abstract

Objective To explore the effect of the combination of bandage contact lenses and artificial tears on corneal epithelial injury, due to correction of blepharoptosis in patients. Methods Thirty-five patients (56 eyes) were included in this randomized controlled trial during May 2013 to May 2018, and randomly divided into observation group (combination of bandage contact lenses and artificial tears) and control group (combination of erythromycin eye ointment and artificial tears), and followed up for 3 months. The corneal wound healing, corneal fluorescent staining (FL), Schirmer test (Slt), break-up time (BUT) and the severity of eye pain were documented and compared by statistical method. Results The scores of FL in the observation group were reduced (t=-3.211, P 0.05; the scores of eye pain, t=-1.800, P>0.05; the corneal wound healing, χ2=1.018, P>0.05; the BUT score, t=1.661, P>0.05). Conclusions The combination of bandage contact lenses and artificial tears is recommended for the early use after correction of blepharoptosis, to alleviate eye symptoms and promote corneal wound healing.
