Overview
Dry Eye Disease is defined as "a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface.' 'By the The Tear Film and Ocular Surface Society. Despite there being a number of factors that impact DED however one factor that has been considered likely is that of a complication from ocular surgery itself. Which can cause both corneal nerve, and ocular surface damage. Therefore this study aims to determine how Lacrfill performs in preventing post-operative dry eye symptoms in those who have recently had unilateral cataract surgery.
