Every surgical procedure includes certain risks and possible side effects, with which the patient should familiarize himself with during his visit to SwissLaser Warsaw.

The occurrence of complications with visual correction is very low, depending upon the chosen method, the patient may have mixed feelings. In the case of most laser correction methods, the pain is very low after a few hours, and the patient can already enjoy improved sight the day following the procedure.

Laser vision correction is a recognized method, and the procedure itself belongs to a group of the most performed operations in the world. Related risks are defined as extremely rare- in great measure this results from the specific preparatory examination and rich experience of our personnel.

Potential complications that may occur with the patient among others:

  • Related to the variable process of healing and the power of the laser may lead to under correction or overcorrection of 20% of the sharpness of vision.
  • he pain can last up to three days and your sight may change over the course of a few months after the procedure (which is a characteristic of the LASEK method).
  • Using the Femto- LASIK method, tears may occur and the feeling of irritant particles in the eye, which usually persists from 4 to 8 hours after the operation.
  • Patients over the age of 45 will probably need to wear reading glasses after correction for nearsightedness.
  • Light sensitivity may occur temporarily or become permanent.
  • In the weeks following the operation, a heightened sensitivity to light may result, which can lead to the halo effect (a round light around a light’s source) or lessen the sharpness of vision at dusk or night blindness (i.e. when driving a car at night). It is possible to reduce the risk with the use of technology, like the so-called Wavefront.
  • As a result of the procedure, the corneal flap may become lodged or dislocated, which can be corrected by a quick procedure.
  • Incision errors during the formation of the corneal flap occur very seldom- this occurrence is limited further by the advanced femtosecond laser technology.
  • The phenomenon of corneal bulging (keratectasia) is extremely rare (1 in 10-40 thousand cases) and can be treated with the cross-linking corneal method.
  • Dry eye, usually occurs only temporarily. Relief and proper hydration are accessible using commonly available eye drops.
  • Postoperative infections are counteracted by using antibiotic eye drops during the first week. In the case of inflammation or discomfort with the eye, please contact us immediately. The use of eye drops containing cortisone may also lead to increased dryness and higher intraocular pressure.
