What is Ocular Surface Disorder?

Ocular surface disorder encompasses different types of diseases which are based on a damage of the surface of the cornea which include dry eye syndrome or typical symptoms after ocular surgery and corneal erosions.

Ocular surface disorder can severely affect eyesight and quality of life. Symptoms may include blurry vision, discomfort or pain, redness and itching, and in severe cases, blindness due to corneal scarring.

The tear film plays a key role in the physiological repairing process. It is composed of 3 different layers (the aqueous, lipid and mucin layer). All three layers must function properly to ensure adequate production of tears in order to avoid symptoms of ocular surface disorder.

Irritation can occur when not enough tears is produced to keep the eye comfortably lubricated or when the eye does not produce an adequate amount of lipids to smooth the tear surface.

The alteration of the lipid layer produces evaporation of the aqueous layer leading to reduced nourishing factors which alter the epithelial cell activity and replication as well as to hyperosmolarity causing death of goblet cells and reduction in corneal glycogen[1]. Irregular lipid layer causes optical aberrations clinically resulting in a reduction of visual acuity and, in general, of the quality of vision. Reduced lubricant power can lead to irritation, heavy/swollen eyelids and foreign body sensation.

Therefore in the treatment of ocular surface disorder, the therapeutical goal should consist of supporting repairing processes and achieving relief of symptoms.

As the only product on the market that imitates the natural tear film LIPITEARTM forms an elastic shield which restores the proper environment for a healthy ocular surface, facilitating the physiological repairing process of the epithelium, and rebuilds a uniform and smooth surface with excellent optical properties.
