Clinical Trial Summary

Adenoviral keratitis(caused by adenovirus) is one of the most frequently diagnosed eye diseases. Most of these infections have symptoms like (Ocular itchiness and irritation, chemosis (conjunctival edema),photophobia, epiphora, foreign body sensation, epithelial keratitis etc.Adenoviral subepithelial infiltration is one of the most difficult complication to treat. Our purpose is to evaluate corneal transparency, recurrence, and visual acuity in patients with adenoviral subepithelial infiltration by first removing the infiltrative stroma with a smile and implanting the same volume of fresh lenticule in the prepared stromal pocket.

Description:

Our treatment of adenoviral keratitis using lenticule implantation and autologus serum it has been applied to patients who have received medical treatment(Antiviral medications, topical corticosteroids ,compresses, artificial tears, and topical cycloplegic) for a long time but have not been successful. In OCT, firstly, the thickness of the adenoviral subepithelial infiltration in the cornea is calculated in microns, and extraction is performed accordingly with Small Incision Lenticule Extraction( SMILE )and fresh lenticule implanted stromal in the same volume. AS-OCT was evaluated using corneal topography and glass-corrected best visual acuity (BSCVA) measurements and electron microscopy. Postoperative complications were recorded during the follow-up period. The patients were followed for one year. No complications were observed in the patients. After the operation, there was an increase in satisfaction and vision. They returned to their daily lives very quickly. Postoperatively, uncorrected vision increased to 6 lines in 12 eyes, seven lines in 11 eyes, and eight lines in 3 eyes.
