The Lasik refractive surgery is the current surgical procedure most commonly used laser to improve vision and treat graduation refractive errors such as myopia (poor distance vision), farsightedness (poor near vision), astigmatism (blurred vision due to the shape of the cornea) and turn can also treat presbyopia (eyestrain, blurred vision which is in accommodation for near objects). This surgery aims to make the daily lives of patients as independent as possible from the use of lenses and even eliminate such use permanently through remodeling cornea. There are other techniques that are based on the use of lasers such as LASEK and PRK.

Action

Lasik action takes place through the cornea cut by the laser in order to mold it. First, a level microincision the corneal surface area in order to create a flap is done. After the flap is lifted and in the area that is exposed to the deep corneal the laser is applied. The laser is applied in precise and very specific areas and this allows you to change the shape of the cornea and correct refractive defects. Finally the superficial cornea is repositioned to its original position, where it adheres without placing points.

Decision

The decision for surgery should be in accordance with the patient and the ophthalmologist, assessing the characteristics and needs of the patient and the characteristics of the eye and cornea. Initial studies are performed with the aim to determine if a patient is not a candidate or refractive surgery. The laser technique is widely used and gives very good results. Refractive surgery can be applied in conjunction with other eye operations.

Procedure

The Lasik procedure is done in most cases with topical anesthesia, ie placing anesthetic drops into the eye. The procedure is quick, lasting approximately 30 seconds. It is very important adequate patient cooperation. The result of the operation is very successful, with a very rapid and satisfactory visual recovery. The patient may reinstate your daily life easily.
