Post-surgical corneal damage

Certain eye conditions require surgical intervention. However, ocular surgery, such as refractive surgery (LASIK), cataract surgery, glaucoma surgery, and corneal transplant, can induce or exacerbate dry eye following the operation.

In the case of refractive surgery, the surgical removal of corneal tissue causes nerve loss from the corneal stroma. This reduces corneal sensitivity and provokes a decrease in tearing and blinking. The purpose of tears is to wash out irritants that may have come into contact with the eye, whereas blinking attempts to spread the tear fluid over the ocular surface.

Decreased tearing and blinking causes the tears to evaporate more easily, causing typical symptoms of dry eye disease. As a result, dry-eye associated symptoms are extremely frequent in patients having undergone ocular surface surgery.

Dry eye may also hinder corneal healing and decrease the optical quality of the cornea. It is thus important to take the necessary steps to identify dryness and use effective treatment strategies.

LIPTEAR™ MULTI  is currently the only product on the market that is clinically proven to imitate the natural tear film [1]. It forms an elastic shield that restores the right environment for a healthy ocular surface, thus facilitating the healing process of the epithelium and rebuilding a uniform and smooth ocular surface for clear and comfortable vision. 

Its unique formula also helps reduce the typical signs and symptoms (pain, burning sensation, blurred vision, feeling of foreign body in the eye, photophobia and excessive tearing) in patients suffering from dry eye.
