Refractive surgery


Refractive surgery means various forms of surgical vision correction from which laser vision correction is most common procedure and clear lens exchange is the next one in this respect. LASIK is the most popular form of laser surgery, followed by surface ablation, i.e. LASEK or PRK. Laser vision correction helps patients reduce or even completely eliminate their dependence on wearing traditional glasses or contact lenses and therefore highly improve their quality of life. Today LASIK is the most common surgery. Laser vision correction was first performed in 1998 but at that time only patients without astigmatism could be treated. Modern third generation laser equipment gives us opportunity to treat patients with low and  moderately high degrees of nearsightedness, farsightedness as well as astigmatism.


LASIK (Laser in-Situ Keratomileusis) combines Excimer laser with procedure called ‘lamellar keratoplasty’. During this procedure a thin flap of corneal tissue is folded back what enable to treat the inner layer of the cornea with laser beam and reshape it. The corneal flap is folded back again covering treated area without placement any stitches. After LASIK procedure patients recover very quickly and experience very little discomfort, if any. In most patients functional vision returns very quickly. Patients who are candidates for LASIK procedure must have sufficient thickness of the cornea. When cornea is too thin or in the presence of moderate or severe dry eye disorder then LASEK or PRK can be used.


PRK (Photo Refractive Keratectomy) is used for vision correction by reshaping the surface of the cornea. During the first step of procedure protective layer of cornea (epithelium) is removed completely. New layer grows back in three to seven days after reshaping the surface with laser beam. Usually functional vision returns during the first week after surgery. The risk is minimal because of no surgical blades are used. PRK gives outstanding results in most patients but some of them may experience certain degree of postoperative discomfort and require a little more time to return to their normal daily activity than patients who underwent LASIK surgery. Hazy vision may occur after surgery but with modern lasers and medicines  used during procedure the number of incidence of haze is reduced significantly. Also the pain associated with this kind of procedure decreases with the use of soft contact lenses during the first healing period.


LASEK (Laser Epithelial Keratomileusis) is surgical procedure that combines some elements of both mentioned above procedures (PRK and LASIK). The difference lies in that instead of removing the epithelium layer a flap of surface epithelium is loosened and moved aside. The layer under the epithelium is treated with laser beam and then the flap is returned to original place. After procedure a protective contact lens is placed to make more comfort during the healing period. LASEK may improve healing and reduce postoperative discomfort and haze.

Wavefront scanning

Wavefront scanning is a newest techniques used before laser vision correction and allows us the measurement of higher order aberrations in the eyes what is not possible during traditional eye exam. Please note that this type of aberration can not to be corrected with glasses or contact lenses. Wavefront is only method to measure this aberration that may be corrected with laser vision correction – eliminate or reduce these higher order aberrations. Sometimes Wavefront guided laser vision correction is called “CustomVue” or “Super Vision Surgery” (better than 20/20 vision). Unfortunately, not all patients may be candidates for this type of laser vision correction procedure. Please contact us for more information and questionnaire.
