PRK surgery is painful



In order to determine the subjective expectations, optical conditions and possible contraindications, a preliminary medical examination is necessary. This takes about 1.5-2 hours and includes the following steps:

  • Determination of the exact subjective ametropia
  • Determination of the corneal thickness with an ultrasonic pachymeter or an anterior chamber OCT
  • Corneal topography to determine corneal curvature and irregularities
  • Measurement of the pupil size
  • Intraocular pressure measurement
  • Examination of the tear film
  • Determination of the amount of tear production
  • General ophthalmological examination of the anterior, middle and posterior sections of the eye using a slit lamp examination
  • anamnese

Soft contact lenses should not be worn 2 weeks before the PRK surgery and hard contact lenses should not be worn 4 weeks beforehand. It is also advisable to use public transport or a taxi to go to the operation, as driving vehicles immediately after the operation is prohibited. Eating and drinking is allowed on the day of the operation. Smoking, make-up or perfume should, however, be avoided.


In order to get the best results and to avoid complications, patients should take the administered pain reliever and anti-inflammatory eye drops according to the doctor's instructions. It is also important to attend all check-ups. These take place after 1-2 days, a week and within the six months following the procedure.

You should avoid the following activities after the PRK surgery:

  • Eye rubbing
  • sporting activities (at least 2 weeks)
  • Exercising the profession (at least 1 week)
  • Sauna, solarium and swimming pool visits (at least 2 weeks)
