Laser eye surgery is one of the most advanced practices done nowadays to correct eye problems. During this surgical practice, light rays are refracted or bent by the cornea in order to direct them on the retina, a layer of cells that senses light. A large part of the eye’s capability to focus depends on the shape of the cornea. Laser eye surgery targets the cornea. Cornea is the external circular part that protects the colored part of your eye and the pupil.
There are 3 different types of laser eye surgery. The recent and the most popular type of laser surgery is known as ‘Lasik’. It involves creating a flap thru cutting off a thin layer of the cornea that additionally enables the laser to target the tissue underneath. The flap is placed back, regenerates naturally and the vision is eventually restored. The major risk of Lasik is corneal ectasia, a condition that weakens and bulges the cornea.
The second most common type of laser eye surgery is known as ‘Lasek‘ or ‘Epiflap’. It involves the fractional elimination of the epithelium to divulge the cornea. The cornea is then reshaped or firmed by the laser. Besides, the external layer of cells is pushed rear and the eye cures shortly after.
PRK has been used for long. This method involves removing the whole epithelial cells on the eye. The major risks of PRK are only pain for some days and regression. As Lasik is used to heal astigmatism, myopia or hyperopia, Lasek is mainly used to correct gentle or common myopia. If successful, laser eye surgery can really reduce your need for eye glasses and inconvenient contact lenses.
These treatments are commonly considered safe. However, the medical area is divided in its opinion over some of the recent advances in eye surgery. This is mostly due to advanced technology and lack of study on the long-term effects of most of these treatments.
Lastly, you should also be very careful when choosing an eye surgeon since it has several limitations and possible complications. Besides, similar to any other surgery, eye surgery has its own set of risks, and surgeons should educate their patients on this matter, its risks, benefits as well as how to prevent them. For instance, Laser eye surgery should be done to healthy adults only. Mild eyesight complications are not considered genuine enough to warrant laser surgery. People with illnesses involving the bones, joints, diabetes and pregnancy should not carry out laser eye surgery.
