This is a surgical procedure that corrects refractive defects (myopia, hyperopia, astigmatism and presbyopia).
It is an outpatient procedure done under topical anesthesia (drops), using either a device called microkeratome or a femtosecond laser to make a corneal flap. Once is done it is lifted so the inner part of the cornea is exposed. Computer controlled aplication of the excimer laser molds the shape of the cornea in a fast and safe way . The eye tracker lets the laser beam be applied only to the correct areas on the cornea. Once it has ended the corneal flap is replaced to its original position.
The procedure lasts 5 minutes per eye. After the procedure is done , plastic protectors are placed over the eyes and antibiotics/antiinflammatory drops are prescribed. Also oral analgesics should be starter inmediatelly. The patient should come back in 24 hours.
The cornea's molding makes the images be focused in the retina , decreasing the need for glasses or contact lenses. The improvement of vision is fast and the patient can return to his/her activities in a few days.
To know if a patient is a good candidate for this procedure ,a complete ophthalmological evaluation should be made ,also a topography with PENTACAM. This allows us to evaluate the anterior and posterior sides of the cornea , its thickness and Factor Q which lets us determin the personalized treatment indicated.
