1 Age and health restrictions for laser surgery
The surgery can be performed from the age of 18. The patient's refractive error should have been stable for at least a year. „The surgery cannot be performed on pregnant or breastfeeding women, nor on patients with certain health conditions such as diabetes, rheumatism, liver and immune diseases or corneal diseases,“ adds MUDr. Ďurkovič, MPH.
2 How high a prescription can laser surgery remove
Laser surgery covers a wide range of vision problems. Laser correction of dioptres is possible for:
-
short-sightedness: up to -10 dioptres,
-
long-sightedness: up to +6 dioptres,
-
corneal curvature (astigmatism): up to -5 cylindrical dioptres.
These values are only indicative; the ophthalmologist always decides whether refractive surgery is suitable.
3 Laser refractive surgery is preceded by a comprehensive examination
Whether a patient can undergo laser eye surgery is decided by the doctor on the basis of a comprehensive eye examination. The examination is contact-free and partly consists of steps that are carried out in normal outpatient practice.
We review your health and, using special diagnostic devices, examine the objective refractive error of the eye, measure your dioptres and intraocular pressure, and check the front and back segment of the eye. If needed, we also carry out additional examinations such as nyctometry - an examination of vision at dusk and after glare - or perimetry - an examination of the visual field, explains MUDr. Ivo Ďurkovič, MPH.
After the examination, the ophthalmologist will assess whether laser removal of your dioptres is suitable for you and recommend the method that can solve your vision problem. At our eye clinic we primarily recommend methods that give excellent visual acuity shortly after the procedure, with minimal risks and post-operative discomfort. If you normally wear soft contact lenses, we recommend not wearing them for at least five days before the planned surgery and examination. Hard contact lenses should be replaced with glasses at least three weeks before the procedure.
How laser eye surgery works
If all pre-operative results are ideal, we start preparing for the laser procedure. So that you are not too stressed, you will get a tablet to calm you down. You will put on a gown, a cap and shoe covers, and
drops to numb the surface of the eye will be applied repeatedly.
We will also apply an anaesthetic around the eye so that you do not feel any pain. Before the procedure you will receive specific instructions from the doctor who will operate on you.
The procedure itself takes place while you are fully conscious and usually takes up to 15 minutes, with the laser working for only a few tens of seconds. The surgery is performed under local anaesthesia.
Some patients feel slight pressure on the eye and, depending on the laser device used, you may notice a smell similar to that of a hair dryer. If the refractive error needs to be corrected in both eyes,
both eyes are operated on during one procedure.
After the procedure you will have a check-up with the operating doctor, where you will receive post-operative instructions specific to your surgery and lifestyle. You will receive eye drops and gel, which should be applied as recommended by the doctor.
Post-operative care and recovery
At our clinic, the price of the surgery includes two post-operative check-ups within one year of the procedure. The first check-up usually takes place one to two days after surgery, when we check how your eye is healing. Based on the results, the ophthalmologist will schedule further post-operative visits.
Recovery after laser eye surgery is generally fast and trouble-free. At first you may feel some discomfort. The level of discomfort varies from patient to patient and
also depends on the surgical method you have had. For example, you may feel a foreign body in the eye, sensitivity to light, blurred vision or fluctuating visual acuity, and your eyes may slightly burn, water or itch. All these symptoms usually disappear quickly.
Within the first few days your vision will improve to an almost optimal level; the complete healing of the eye and stabilisation of vision takes about two to three months. Because of the risk of infection, protect your operated eyes from injury after the procedure, do not rub them and avoid infectious, dusty or smoky environments. For several weeks we recommend limiting swimming and saunas and avoiding contact sports with a risk of impact. Post-operative restrictions and their duration may vary,
so for a quick recovery it is important to follow the instructions and recommendations given by your surgeon.
