Abstract

Objective To investigate the clinical effects of amniotic membrane transplantation in treating secondary recurrent corneal erosions caused by corneal abrasion.Methods Thirteen eyes of 13 patients with secondary recurrent corneal erosions caused by corneal abrasion that were resistant to various conventional medications underwent corneal epithelium debridement,and amniotic membrane transplantation.Postoperative examinations were conducted for visual acuity,corneal transparency,fluorescein staining,amniotic membrane turnover,recurrence,and complications.Results Amniotic membrane started to dissolve in 3-5 days after operation,and most of it fell off within 1-2 weeks.Thereafter,patients' visual acuity was markedly improved.Slit-lamp examinations showed that the corneal turned transparent,the epithelium recovered,and the fluorescein staining were negative.After a follow-up time of 6-83 months,12 of 13 eyes (92.31%) healed with no complications; only one eye experienced a recurrence in four months.Conclusions Amniotic membrane transplantation is a safe,effective,and low-cost treatment for those who suffer from recurrent corneal eros ionsthat are resistant to various conventional medications. Key words: Recurrent corneal erosion; Amniotic membrane transplantation
