Good eyesight and vision are essential for a person’s life. The conventional way of correcting vision is through contact lenses or spectacles. In recent years, however eye laser surgery has emerged as the popular alternative. The laser is focused at the cornea, the iris (the outer circular structure that protects the colored part of eye) and the pupil. For instance, in correcting myopia, the laser will be set to decrease the cornea’s thickness. Thus, it makes it possible for the eye to get the vision back or to bring images into focus perfectly.
Laser eye surgery types
There are vitally three different sorts of laser eye surgery. The most prevalent type is termed as eye surgery Lasik. This process mainly involves creating a flap efficiently by cutting off cornea’s thin layer that further enables the laser to focus for the tissue beneath. The flap is simply placed back, and it regenerates naturally. The results are quick and vision is restored immediately.
The next most popular kind of laser surgery called as Lasik or Epiflap surgery. This method primarily involves fractional removal of epithelium for revealing the cornea. Later, cornea is reshaped or firmed accurately by a laser. Furthermore, the outer cell layer is pushed back and the eye heals and vision restores shortly after.
The prevailing laser surgery method for years was the prk eye surgery. This type of laser surgery for eye involves the removal of the entire epithelial cells. While Lasik is utilized to treat severe myopia or hyperopia, Lasik is only utilized to correct average to mild myopia.
These laser treatments are generally regarded to be safe. The procedure has over 95% success rate. But, the medical community is alienated in its opinion over few of the latest improvements in eye pain treatments and surgery. This is mainly because of the newness of the advanced technology and a lack of research on associated long term effects of the treatments. Furthermore, like any surgery, eye surgery boasts its own set of limits and risks, and eye doctor must educate their patients on this matter. It is not uncommon for patients to suffer complications. Though laser eye treatments are relatively safe procedure for correcting several eye impairments, there are some common risks associated with laser eye treatment. The most common one includes;
Overcorrection or under correction – All patients may not respond to the laser eye surgery perfectly. Sometimes, a doctor even after surgery can suggest patient to wear corrective lenses to have clear vision. A doctor can also suggest an enhanced laser eye surgery to enhance the initial procedure which resulted to overcorrection or under correction.
Eye infection –The chances of eye developing infection after laser treatment is usually very low, but still there is a risk of this happening.
Flap loss –During laser eye treatment, a flap tissue will be created over cornea. This flap tissue might come off if patient directly touches eye or injuries eye within 1 day after the surgery.
Laser eye surgery must be done only on a healthy adult. Conditions such as diabetes, pregnancy, or illness involving the joint and bone pain can often times rule out the probabilities of laser treatments.
