(Laser-Assisted in Situ Keratomileusis) Is an outpatient procedure used to treat nearsightedness, farsightedness and astigmatism. The surgery uses a laser to shape the cornea (the clear, round dome on the front of the eye) to improve the way the eye focuses light rays onto the retina at the back of the eye.
During the LASIK procedure, the ophthalmologist creates a thin layer on the cornea with a microkeratome or a laser beam. The surgeon bends the back layer and accurately removes a specific amount of corneal tissue beneath it, using an excimer laser. The layer is put back in place and heals by itself. In people with myopia, LASIK is used to flatten an abnormally steep cornea. In people with hyperopia, LASIK is used to achieve a steeper cornea. LASIK can correct astigmatism by molding an irregularly shaped cornea, making it smoother and normal.
Is the ophthalmology subspecialty devoted to the study and management of eye socket (cavity where the eye is located), eyelid, tear duct and ocular loss problems. Surgery is performed for functional and aesthetic purposes, yielding surprising results in cases where, for various reasons, the eye loses its shape and natural appearance, restoring its beauty and harmony.
Cataract is a clouding of the crystalline lens inside the eye which loses its natural transparency and lets less light into the eye as we age. The light that gets through to the retina is diffuse or disperse, which results in out of focus and blurred vision. Through cataract surgery, the cloudy crystalline lens is removed through a small incision with the assistance of advanced technology equipment, and replaced with a clear artificial lens called intraocular flexible lens that folds into the capsule where the crystalline lens was. Cataract surgery is often performed as an outpatient procedure and does not require hospitalization.
It is an ocular pathology that consists in the deformation and progressive change of the cornea, which is the transparent tissue located in front of the iris and pupil.
In keratoconus, corneal thinning occurs due to normal eye pressure that pushes the weakened surface and deforms it. The normal round shape of the cornea becomes conical, whereby it is also known as “Conical Cornea”. This deformity causes significant visual changes in the patient, leading to blurred and distorted vision. The extent of this disease is from mild to severe. The progress is variable, generally slow and can stop at any time. Only in extreme cases it may cause blindness. Keratoconus is a rare eye condition. It is estimated to affect 1 in 4,000 people but it occurs more often in patients with Down syndrome, allergies or amaurosis. Keratoconus may be suspected when the patient requires too frequent changes in graduation of his eyeglasses, which generally leads to astigmatism and/or myopia. A Pentacam examination is recommended for these patients, which allows using several parameters and/or values to consider through observation, the need to place Intrastromal rings, cross linking, or corneal transplantation.
The retina is a thin nervous tissue on the back of the eye where light rays are focused and transmitted to the brain tissue. The vitreous is a jelly-like substance that fills the eye and is connected to the retina, the optic nerve and many blood vessels. Problems with the retina and the vitreous, including retinal tears, retinal detachment, intraocular severe infection (endophthalmitis) and trauma, can cause vision loss and even blindness. Surgery can correct problems before vision is lost or prevent further deterioration.
