Lasik

What is Lasik eye surgery?
LASIK (Laser/Insitu Keratomilieuxis) is currently practiced as an alternative to the treatment of refractive errors.
In this method, where laser and microsurgery are combined, a piece of the transparent layer of the eye is removed with an average coverage of 160 microns (thin as paper) by means of a special microkeratome for automatic lamellar keratomilieusis under the microscope. The Excimer laser is applied to the transparent layer bed. The valve is put back in place.

  • In the Lasik method, a 180 micron thick covering is removed from the 500 micron cornea using a microtome to protect the sensitive layers.
  • Laser beams reconstruct the cornea to eliminate the need for glasses.
  • The removed lid is closed in the same place. Thus, the patient does not feel pain or pain.

What defects should be corrected with LASIK?
What are the advantages of LASIK over glasses and contact lenses?
Myopia is the most common eye defects. However, nowadays not only nearsightedness but also nearsighted astigmatism, farsightedness, farsightedness, astigmatism and mixed astigmatism are treated with LASIK.

The vast majority of patients with eye defects use glasses and contact lenses to correct refractive errors. The correction with glasses is reversible and safe. However, as in the case of high myopia, for example, the increase in the thickness of the lenses, especially at the edges, leads to a certain loss of the visual field and also creates a cosmetic problem. High index lenses have solved this problem of thick lenses. But these are quite expensive. The disadvantages of lenses such as fogging, scratches, steam breakage and rain are eliminated by this method. Correcting eye defects with contact lenses is less common than using glasses. The vast majority use soft (hydrophilic) contact lenses and a small portion hard (eye permeable). The complications associated with wearing contact lenses are well described. Most are lightweight. These include, for example, abrasions of the transparent layer, lack of oxygen supply and toxic corneal epithelial reactions to contact lens protective solutions. The most serious complication of contact lenses is ulcerative keratitis. This leads to clear coat causes which also lead to vision loss and rarely even clear coat transplantation.

What is the difference between LASIK and other refractive surgery methods?
Two methods were developed before LASIK. Deep incisions were made in the transparent layer during a "radial or astigmatic keratotomy", an operation during which the eye was scraped with a knife. However, during long-term follow-up, the results proved to be very volatile. In a significant number of patients, farsightedness developed with scarring at the edges caused by poor wound healing. Small punctures in the clear coat are common during operation. Thus, this can lead to a risk of intraocular infection and possible loss of vision. The incisions heal slowly and weaken the structure of the eye. In the years following surgery, injuries to the eye can easily cause perforation of the scar site. The other method is to apply the excimer laser called PRK to the upper layers of the transparent layer rich in cells and nerves. After this method, the patient felt a lot of pain, his eyes were closed for two days, and he took medicine for a long time (3 months). These, in turn, pose a risk of clear coat cloudiness and eye count return. On the other hand, thanks to the paper-thin layer removed in LASIK, the laser is applied to the filler layer (stroma) poor in cells and without nerve; The disadvantages mentioned above are overcome.

What are the benefits of LASIK?

  1. LASIK is a method that has no alternative, especially for high-grade eye defects. Up to -14 myopia, up to -4.0 myopic astigmatism or up to 4 mixed astigmatism, up to +6 farsightedness and up to +6 farsighted astigmatism can be treated. – No pain is felt during and after the operation. No needles, no anesthesia, etc. are required for the procedure. The process takes a few minutes.
  2. Both eyes of the patient can be operated together. The eyes are not closed. The patient can walk home. It can do all kinds of (not dirty) jobs the next day. Haze (haze) causing blurred vision does not develop.

What are the disadvantages of LASIK?

  1. It is a more difficult surgery. Requires additional equipment and a sterile environment.
  2. Although there are complications such as valve rupture and loss, valve rupture, very thin valve, very thick valve, foreign body under the valve and irregular astigmatism, most of these can be resolved without causing serious deterioration in visual acuity.

Our announcements for LASIK candidates:

  1. Whether or not your eye is suitable will be decided after a series of examinations and examinations. For this reason, you should listen carefully to your doctor. You should discuss all your questions with him.
  2. Before LASIK, your transparent layer should have its normal shape. Contact lens wearers must have removed their soft lenses for 1 week and their hard lenses for 2 weeks. Cut the eye contour cosmetics you use 3 days in advance.
  3. After LASIK, there may be a slight tingling in the eye as if an eyelash has disappeared. It disappears within a few hours with the use of the administered drops.
  4. Never ask your doctor for a guarantee for surgery. Such a guarantee cannot be given in matters of health. However, be aware that you will not need glasses with a 99% probability.
  5. Do not rub your eyes for 2 weeks after LASIK. This process prevents the cover from peeling and sticking, which is removed and put back in place. This can lead to serious complications.
  6. After the operation, you can close your eyes and take a bath and wash your face.
  7. Patients should try to attend check-ups recommended by their doctor.
  8. Remember that this process is widely used around the world, including the United States and European countries, and has solved the problem of glasses for more than hundreds of thousands of people.
