Eye Laser Treatment

What is Eye Laser Treatment?

Lasik surgery is called refractive surgery, which is applied to patients who use glasses or contact lenses due to eye disorders to provide clear vision without glasses.

LASIK is a surgery to correct eye deformity using laser beams. Lasik surgery is the most frequently applied and most reliable laser eye surgery method all over the world and in our country. In order for a clear image to be formed, the rays coming into our eyes must be properly refracted and focused on our retina.

This focusing process is done by the cornea and lens in our eyes. In eyes with refractive errors, the light cannot be refracted correctly and a blurred image occurs.

Although LASIK surgery is known as eye-scratching surgery among the people, in fact, the eye-drawing procedure is not performed.

In LASIK surgery, an incision in the form of a valve called a flap is made on the outer layer of the eye, which we call the cornea.

This flap was made with blades called microkeratome in the past. Today, it is done without blades with femtosecond lasers (INTRALASE). Later, this cover is removed and laser beams are applied to the area under the cornea and the cornea is reshaped.

The flap is covered again and a rapid recovery is achieved. Thus, correct refraction of the rays is ensured, and refractive error is corrected and clear vision is provided.

In which eye disorders is LASIK surgery applied?

The refractive errors that can be corrected with LASIK surgery are myopia, hyperopia, and astigmatism. These eye disorders are corrected with the help of glasses and contact lenses. When glasses or lenses are not worn, the patient sees blurry. In other words, the patient is dependent on glasses and lenses. With LASIK surgery, the need for glasses and contact lenses is eliminated.

1. a) Myopia is the problem of not seeing the distance clearly. Incoming rays are focused in front of the retina and distant objects appear blurred.

In the near future, there is usually no problem. The corneas of these patients are shaped and straightened by LASIK surgery, allowing the light to focus on the retina.

1. b) Hyperopia, distant objects are seen clearly while near objects are blurred. While reading something, the letters get mixed up and the eyes get tired. Incoming rays are focused behind the retina. With LASIK surgery, the cornea is erected and the rays are focused on the retina.

1. c) Astigmatism, due to the structural deformity of the cornea, the rays focus diffusely. Both distant and near objects appear blurry. With Lasik surgery, the shape of the cornea is corrected and the light is focused properly.

Who is LASIK surgery suitable for?

Some prerequisites are required in order to have LASIK surgery. These;

• Be over 18 years old (preferably 21 years old). The progression of eye numbers stops at this age.

• The degree of eye disorder is at values ​​that can be corrected with LASIK surgery.

Myopia up to number 10

o Hyperopia up to number 4

o Astigmatism up to number 6 can be corrected with LASIK surgery.

• The number of glasses or contact lenses have not changed in the last 1 year.

• Adequate thickness of the corneal layer.
• Normal eye surface map, which we call corneal topography.

• Absence of any other eye disease other than eye disorder.

If you have these pre-criteria, you may consider having lasik surgery. Your doctor will evaluate whether your eye is fully suitable for surgery by performing detailed examinations and tests.
