Bandage contact lenses for the treatment of acute ocular chemical injuries

Abstract

Objective To observe the application efficacy of bandage contact lens(BCL) for the treatment of acute ocular chemical injuries. Methods Prospective case-control study. Seventy-seven eyes of 50 patients with ocular chemical injuries were randomly divided into 2 groups: observation group, 39 eyes of 25 patients and control group, 38 eyes of 25 patients. All patients were treated with routine anti-inflammatory and reparative treatment after emergency treatment. The observation group received normal treatment combined with BCL.The changes in corneal epithelial, symptom scores, corneal epithelial healing time and complications after treatment were observed and recorded. Results All BCLs were successfully fit patients of observation group, no any related complication occurred. The scores of symptoms and corneal fluorescence staining in observation group were significantly lower than those in the control group at 1, 3 and 7 days after treatment(all P<0.05). The difference of scores of the two groups were not significant between before and 14 days after treatment (P=0.311). The average time of corneal epithelial healing in observation group was (2.670±0.982) days and (5.870±1.711 )days in the control group, the difference was statistically significant between the two groups(t=-10.769, P<0.05). Conclusion Application of BCL for the treatment of acute ocular chemical injuries is effective for shorting the time of re-epithelialization and reducing postoperative pain.
