FacebookBasis of Operation
The operation using the excimer laser is called photorefractive keratectomy. using the laser, thousandths of milimeter of the cornea surface is removed, changing its curvature and correcting the dioptric error of the eye.The deeper layers of the cornea remain untouched, and this treatment does not affect the original strenght of the cornea either. The excimer laser removes a part of the cornea through " photoablation " , i.e. evaporation using light. The instrument is controlled by computer which, after setting the number of diopters and the axis of astigmatism, calculates the operation zone and depth of cut.
Preoperative Examination
Each client interested in being operated on in our clinic is examined thoroughly to determine if the procedure is right for him or her.
The use of the excimer laser is not appropriate for clients:
- younger than 18 years old
- with unstable nearsightedness
- with serious deformations of the retina or with some diseases of the cornea
- who are pregnant
- suffering from diabetes, rheumatism, and other diseases
- with a pacemaker
- with a tendency to develop keloidal scars
The doctors first perform a thorough examination to determine your health condition and your refractive error. Only then we can decide if you can be helped by our excimer surgery.
Two weeks before the operation, contact lens wearers must stop wearing their contact lenses, as the lenses could slightly change the curvature of their cornea. You must not use any make-up both on examination and operation day.
The excimer laser operation will solve your distance seeing problems. Clients who are above 40 years of age and use glasses only for reading are not long-sighted. This defect is called presbyopia, which is inability to focus sharply for near vision due to loss of elasticity of the lens of the eye. We don't operate this at present.
