Facts about Eye laser surgery

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.

The science behind the Lasik eye surgery

The concept of Lasik eyesurgery came in to the market during the early 1990’s.Nearly millions of the people took advantage if this eye surgery Lasik and put away of their eye glasses forever and ever. Lasik eye surgery cost is really cost effective and ends up with positive results in most of the cases.

Concept of Lasik surgery

Acronym for Lasik in relate to medical term is “laser in situ kertomileusis”. This process makes use of the low level laser to provide or reshape to cornea, which the eyes transparent is covering. In cases of near or far sightedness the shape of the cornea is misshapen and causes blur vision of certain distances. Once the reshaping of the cornea is done the patient can expect 20/20 and 20/40 vision.

With the patients having the problem of near sightedness, the cornea has too much point at the crown of the curve and the eye laser surgery is used to remove the excess tissue and removes the point. Whereas in the case of far sightedness, the cornea is too flat and the laser surgery is made used to remove the tissue on the perimeter and provides a proper shape to the curve. Lasik surgery is one of the effective eye treatments of a number of vision problems

With the advancement in the field of laser science, a great pace has been made by making use of the laser technology and to treat other vision problems as well. A person suffering from the cataract problem gradually loses their vision due to the calcium deposits. With low level laser technology, the ophthalmologist now can quickly and safely open the cornea and can remove the complete cataract through cataract eye surgery.

Laser eye surgery

Laser eye surgery is now available in order to correct your eye related defects and provides you with the complete and clear vision within a short period of time. The success of the laser surgery has gone very high. This procedure makes use of the laser light instead of the scalpel so as to remove the tissue. The laser light emits a painless UV light in order to remove the microscopic layer of cornea and reshapes it into correct refractive errors.

During the laser surgery, a thin layer of the corneal tissue is created and its gently folded back prior to the excimer tissue reshapes the underlying tissue. Then the flap is replaced in its original position. This excimer laser is a new cool type of laser. The excimer laser vapoursies a small amount of tissue every time when this laser light falls on the surface of the eye. Laser surgery is performed by making use of local anesthetic eye drops and it takes maximum of 5-10 min per eye. The time taken by the excimer tissue in reshaping the cornea is less than a minute. Advantage of this laser procedure is you can free from stitches and bandages. It just requires a few drops of local anesthesia to complete the laser operation successfully.
