What is myopia surgery?
myopia surgery is the possibility of treatment for people who are short -sighted and rely on glasses or contacts to see objects that are far away. Myopia occurs when the eye grows longer than usual, causing the eye to focus in front of the retina instead of it, creating a blurred image. The nearsightedness surgery for the corneal corneal correction correction is transformed by corneal or implants to allow the incoming light beams to directly focus on the retina.
refractive eye operations are the most popular and widely used treatment for myopia. There are four types of refractive eye surgery: photorefractional keratectomy (PRK), laser in-world keratomileusis (lasik), laser epithelial keratomileusis (lasek) and epithelial laser in-keratomileusis (epi-alike). These types of nearsightedness treatment use the laser to transform corneal curvature, and the results allow people to stop using glasses or contacts to correct their proximity.
board uses either alcohol nEbo laser energy of the cornea of the cornea to have access to the surface of the cornea called the tree to transform the eye. Doctors will recommend board people with dry eyes or thin cornea who would probably have problems and complications associated with Lasik surgery, which is very similar.
Lasik procedure requires the surgeon to cut a flap of several layers of the cornea to transform the tissue underneath. The corneal guy then stands in place. The Recovery time after a PRK surgery is longer than the lassist, because the eye must regenerate the epithelial layer that has been removed during the procedure.
Lasek is a similar lasik and a board. During the lasso procedure, the outer layer of the cells is weakened and then the thin flap is made only from the epithelial layer, and it is removed to transform the cornea using a laser. The layer is then placed back to the original position. Epi-Land also requires a flap of the epithelial layer to be created butThe work with a blunt, plastic tool and creates a suspended flap. Also, the Lasek does not use an alcohol solution to weaken the outer layer that can kill or damage the epithelial cells.
Two other types of myopia surgery use implants to permanently repair myopia. Implants with nitroocular lenses are contact lenses that are located either between the iris and the lens or between the cornea and the iris. Implants with intraocular lens cannot be felt or seen and these implants can be removed if the person's eye constantly changes.
Implants of the corneal ring are used to align the corneal curvature and are implanted around the edges of the cornea to transform the eye. Implants are made of clear acrylic and are shaped as half circles; They can also be removed. Implants are usually only for people with slight nearsightedness.
