What is Refractive Surgery?

Beginning in the cornea before refractive surgery, rapidly increasing It is the most exciting surgery in our age, whose application area is expanding with refractive lens surgery techniques with interest and confidence.

Since the 1970s, a different originality has been achieved by the treatment of visual defects in more than 50 million people all over the world. This freedom offered them different alternatives that they did not experience while wearing glasses or contact lenses. With the introduction of Excimer Laser into the field of use, a new era has been opened in ophthalmology.

Today, 25-40% of the population in the 25-45 age group request and practice in the correction of refractive errors Excimer Laser is the first option.

The leading advantages of refractive surgery are a natural appearance, unlimited benefit from sports activities, less discomfort in environments such as wind, rain, dust, and economic relief from lifetime financial costs.

The optical power of the eye is mainly due to the curvature of the corneal anterior surface. This is equal to 2/3 of the total refractive power of the eye. (+48D). In procedures classified as keratorefractive procedures, new refractive power is gained by changing the shape of the cornea. In this last case, the refractive error of the eye has disappeared or has been greatly reduced.
While excimer laser applications in the corneal tissue determined the limits of refractive surgery in previous years, today the diversity of refractive surgery is increasing with the surgery of the lens, which is the second major refractive medium of the eye, and the additions to the eye tissue.

How is Refractive Surgery Application?

Contact lenses should be discontinued when the decision is made. Cosmetics should not be used for a while. In the operation, the eyes are anesthetized with only topical drops. The patient must remain calm. Precautions are taken for stress. The eye is cleaned by wiping. The procedure is done under a microscope. A vacuum ring is used to fix and harden the cornea. Vision is impaired. After the flap preparation is completed, the flap is separated and Excimer Laser ablation is performed on the clean and flat corneal bed below.

Duration, energy and spot structure are predetermined. Transaction confidence is increased with the iris recognition feature in some devices. The flap is closed, attention is paid to fit it, and the procedure is terminated by placing a bandage contact lens if necessary. Refractive surgery may differ in the correction of refractive errors. The application may vary depending on the eye structure and the patient's request. LASEK-Epi Lasik is only the removal of the epithelial layer with the help of alcohol and superficial ablation. It is applied to people with thin corneal thickness. Recommended for people who do martial arts.

İ-Lasik and Lasik were the most common forms of application. PRK, Lasek, Epilasik are used less frequently. Near vision lasers can be misleading. Lamellar flap preparation in the cornea with Femtosecond Lasers, personalized wavefront evaluation before the excimer laser application, and the use of iris recognition method in the application are the most adopted current treatment methods.

Thus, both the quality of vision and the scarcity of postoperative problems are ensured. A small number of patients may experience deviation from the target or regression problem. 3-6 months after this Re-treatment may be required by raising the corneal flap in the evaluation.
