[Examination for laser eye surgery]
Visual acuity determination is performed on a device that does computer calculation of vision, measures curvature and corneal thickness, and then it is subjectively checked how well the patient sees.
During the examination, a dominant and non-dominant eye is determined. Since, as a rule, the dominant eye is used to see in the distance, during laser nearsightedness correction non-dominant eye is left with a part of the diopter (up to -1.25) with the aim of making the remained minus annul the plus which progresses as we age, and thus good near vision is enabled.
This way, the dominant eye from which the diopter is completely removed, can see at a distance, and the non-dominant eye (with a small "minus" left) can see up close. By combining images in the brain that come from both eyes, the patient clearly sees at a distance (driving), at a medium distance (computer work) and up close (reading).
After determining the dominant eye, the patient has soft contact lenses inserted in both eyes in order to simulate the vision he or she will have after the laser eye surgery.
The following tests are the measurement of the eye pressure, the determination of the tear film stability, the pupil dilation, the examination of the ocular lens and the posterior eye segment, as well as re-measuring the diopter on the dilated pupil by the so-called skiascopy. Such a thorough examination takes about 1 hour.
Instructions before the operation:
There are no strict instructions on how to prepare for the operation, but we always advise you to:
- evening before the surgery wash your hair because postoperative recovery requires you not to bend over or make your face wet for a certain time
- put on a buttoned shirt, a cardigan or a blouse, so you do not have to take off your clothes over your head and put your recently operated eye at risk
- cook meals for the next few days because it is not advisable to expose the recently operated eye to heat and steam
- before the operation you are free to eat and take your medications (if they are regularly prescribed), meaning that it is not necessary to prepare yourself additionally for the surgery
- bring someone with you who will take you home by car or take a taxi since it is not advisable to use public transport because of possible injuries and infections on a recently operated eye.
