Femtosecond Lazer
Microkeratomes are the tools with a special blade used in LASIK surgery for preparing flap. The required flap is prepared by moving the blade across the cornea and cornea laser surgery is performed. The most important and hazardous part of LASIK surgery is the preparation.
Femtosecond lasers are lasers developed for the flap preparation aspect of the surgery, which is the most critical. They achieve flap removal by replacing the keratome without any incision.

Femtosecond laser pulses made without touching the cornea create laser spaces with a depth of 1 micron.
The laser shots made consecutively in 1/quadrillion of a second are seen as laser points together.

Laser points vaporize the tissue by creating water and bubbles and form a linear flap opening with a width of 2/1000 of a millimetre...

 




Lazer - Lasik

Your doctor will examine your eyes before the operation. Your degrees of myopia, hypermetropia, and astigmatism will be determined.
Before the treatment, rigid and gas permeable contact lenses must be removed and not worn for 2 weeks and soft contact lenses for 3 to 5 days.
This treatment is inconvenient for some eye and systemic diseases such as rheumatismal diseases and diabetes. Your doctor will tell you about these issues before the treatment. However, if you have a special disease or a special medicine you have to use, inform your doctor as usual.

The LASIK treatment will take 8 to 9 minutes for both eyes.

After the LASIK treatment, you have the best sight, the same as you had using glasses or contact lenses...

 




Lazer - PRK

PRK is an operation almost similar to LASEK: There is no flap formation. The difference from LASEK is that no alcohol is used to remove the epithelium (the uppermost layer of the cornea) and that the epithelium cells are not put back after the laser operation.

Contact lenses are placed on the eyes of the patient and the epithelium regenerates in 2 to 3 days. The patient feel a discernible pain during the operation. The PRK operation may be an option for patients with thin corneas.




INTACS

Cornea rings are round rings made of PMMA substance which can be inserted inside and near the outer part of the cornea.

They are inserted inside the cornea through special surgery sets and techniques. In this surgery, the ring channels can be formed by using the surgery set of the Intacs device or Femtosecond laser, which is a new system. In both systems, the surgery is performed without touching the vision area in the centre of the cornea. The rings act by applying pressure around the cornea and smoothing this area.

Cornea segments have started to be used for treating low myopia. However, since there is a limited area of use in the eyes with very low myopia and without astigmatism and since LASIK results are more accomplished, their use for myopia treatment is very rare. Today’s actual and very successful area of uses are Keratoconus patients and cornea complications caused by unsuccessful or inaccurate laser surgery...
