In order to get clear vision, the eye’s cornea and lens must refract light properly so that images can be focused on the retina of the eye. If the cornea can’t work properly the images become blurry. In this refractive error condition people may need glasses or contact lens to correct vision or a laser surgery. Lasik surgery (short for laser-assisted in situ keratomileusis) is an eye laser surgery that changes the shape of the cornea (the clear covering on the front of the eyeball) permanently by a laser in order to correct vision and eliminate the patient’s dependency on eye glasses or contact lenses. Laser surgery is extremely favored by fashion people who are myopia.
However Lasik surgery is not suitable for everybody, even those with myopia, hyperopia and astigmatism. Comprehensive eye examinations, using a number of medical equipments will be taken and a few questions will be asked before you can undergo laser surgery. First you should be at least 18 years old for Lasik surgery(21 in some cases, depending on the type of laser surgery), since the vision of people younger than 18 continues to change. Your eyes must be healthy to have a laser surgery. The curve of the cornea, the size of the pupils and the thickness of the cornea is measured to determine if there is enough cornea tissue left for a Lasik surgery. Lasik surgery may not be recommended for patients with diabetes, rheumatoid arthritis, lupus, glaucoma, herpes infections of the eye, or cataracts. People who are pregnant or breastfeeding are not recommended for Lasik surgery. After the examinations, the laser surgery doctor will tell you the risks, benefits, possible complications and alternative options, such as PRK and LASEK. After all these, your eye doctor will do Lasik surgery for you.
