Safety of Tinted Soft Scleral Eye Shields When IPL is Applied on Eyelids

Patients with dry eye disease due to meibomian gland dysfunction will be treated with one session of IPL applied directly on upper and lower eyelids, when eyes are protected with tinted soft scleral eye shields which prevent IPL from penetrating into ocular structures. Ocular structures will be examined with various tests (including: biomicroscopy, OCT and specular microscopy) at baseline and at 10 minutes after IPL, 24 hours after IPL, and 7 days after IPL. In addition, visual acuity will be measured at each of these times, and the patient will report of any visual symptoms at each of these times. The primary objective is to verify that no morphological or functional changes occur between the baseline and the 7 days follow-up visit.
