Laser Refractive Surgery

Imagine your day without the need for glasses or contact lenses. By using the most modern equipment, laser refractive surgery is nowadays more accurate than ever before, offering excellent results in the treatment of myopia, hyperopia, astigmatism and in certain cases of presbyopia.

The correction of refractive errors with the use of a special infrared laser beam of 198nm in wave-length, was first used in 1998. The concept on which it was based is to alter the way cornea focuses light by changing its curvature.

Carl Zeiss, a pioneer in the field of developing ophthalmologic equipment, have introduced MEL 80, a last generation excimer Laser which incorporates all the modern technologies in the field of refractive surgery.

1. Refractive Examination : Precise examination of the degrees of myopia, hyperopia, astigmatism and ascertainment that they have been stabilized over time.

2. Corneal Topography : This is the examination of the anterior but more importantly of the posterior corneal surface for ruling out any pathologies or other abnormalities.

3. Aberrometry : This is the examination studying the diffraction of light inside the eye. Any disorder should be taken into consideration when planning the laser treatment.

4. Measurement of the Diameter of the Pupil’s Eye : An important parameter when planning Laser treatment since it affect the amount of tissue removed.

5. Corneal Pachymetry : We determine the corneal thickness throughout its entire area. The sufficiency of the corneal tissue is essential for choosing the proper method of laser treatment.

6. Clinical Eye Examination

  • Clinical examination of the cornea
  • Intraocular pressure measurement
  • Evaluation of tear production: Laser procedures may temporarily reduce tear function.

7. All the above examination’s data are imported into a special computer program (CRS Master), where the treatment is planned in advance and then is transferred to the laser.

The procedure lasts less than 20 minutes for both eyes.

The steps followed in the LASIK method are the following:

  • Anaesthetic eye drops are instilled on the eye.
  • The patient lies down on a special bed. An eye-lid retractor will ensure that the eye remains open throughout the whole procedure
  • The patient focuses on a blinking light.
  • With the use of a precision device called keratome, a thin incision on the corneal surface is performed (the flap).
  • The corneal flap is then folded carefully.
  • Within a few seconds the laser ablates the necessary corneal tissue with the greatest accuracy and precision.
  • After the tissue ablation, the corneal flap is repositioned back into place
  • If necessary, a special therapeutic contact lens is applied over the cornea

The steps followed in PRK are the following:

  • Anaesthetic eye drops are instilled on the eye.
  • The corneal epithelial tissue is removed with a special sponge. (Epithelial tissue is reproduced within a few days after the procedure).
  • Within a few seconds the laser ablates the necessary corneal tissue with the greatest accuracy and precision.
  • A special therapeutic contact lens is applied over the cornea.

Immediately after the procedure, there may be some eye irritation, foreign body sensation, photophobia, tearing and blurring of vision. Mind to bring with you a pair of sunglasses that will ease the symptoms. There may also be an itching sensation but you should not rub your eyes. All of the above mentioned symptoms are usually expected after the surgical procedure. In case that something are worries you, then immediately contact us.
Furthermore:

    • You will be given a special eye mask to wear during sleep.
    • Try to relax from work the next day.
    • Avoid contact with water.
    • Avoid contact with dusty enviroment for 1 week.
    • You may drive as soon as you feel comfortable
    • Avoid the use of cosmetics near the area of the eyes for at least 20 days.
    • Avoid for about 2 weeks intense work-out and swimming (pool or sea).
    • You will be re-examined the next day and also in regular intervals..

 

Mind to follow the medication and all the above mentioned instructions!
