Improving and Protecting the Ocular Surface
The abrasion healed within 3 days after removal of the amniotic ring. In the next 3 months, the patient’s vision improved significantly, to 20/70 OD and 20/100 OS, respectively.
The patient was continued on a regimen of gel artificial tears and preservative-free artificial tears. However, about 7 months after her first episode of corneal abrasion, a 2- x 2.5-mm central epithelial defect recurred in the left eye with reduced vision, leaving her 20/200 OD and 20/400 OS. After insertion of a bandage lens and then another amniotic ring, the epithelial defect healed in 2 weeks and the vision of the left eye improved to 20/70.
She then continued on the preservative-free artificial tear regimen and topical cyclosporine. After 5 months, she was still unable to read (she was 20/200 OD and 20/100 OS), and moderate to severe superficial punctuate keratopathy continued to exist in both eyes. By then she had begun to have problems putting drops in the eyes so often.
