Dry eyes are caused by many factors, but mostly it is a problem. tearboth in quality and quantity. It’s a malfunction in the meibomian glands. They are found on the eyelids and have the function of secreting fats that lubricate and maintain the stability of the tear film.

These new technological advances introduced into the operating room are especially used in the surgery of farsightedness, myopia, presbyopia and cataracts.
By applying various constant series of short-intensity micropulses to the eyelid, it is possible to improve the blood circulation of the eyelids, reduce inflammation, eliminate abnormal veins surrounding the eyelid, and activate the meibomian glands.
“Eye surgery, whether for presbyopia, myopia, hyperopia or cataracts, is one of the fastest and safest interventions currently available,” explains the ophthalmologist at the Guipuzcoa Polyclinic. Hector Farina. “These procedures are now fully documented, performed quickly and with excellent results,” adds Farina.
