Step by step – the process and steps of a laser eye surgery
What to expect during the examination?
- be prepared for a completely painless examination that takes 1.5-2 hours
- the most important tests are carried out by two experts independently (a list of our assistants and ophthalmologists can be found here)
- refractive errors are measured using five different methods
- the expected outcome of your treatment is presented to you in a personalised Medical Guarantee Certificate
- during the pre-operative examination, we collect tens of thousands of data that enable us to plan the ideal treatment
How should you come to the examination?
- as you will receive pupil-dilating drops (mydriatics), after the examination, your vision will be blurred for even up to an entire day, thus it is advisable to come with a companion and/or arrive by public transport
- you should not wear soft contact lenses for 4-5 days before the tests, semi-rigid and rigid lenses for at least 2 weeks in order to obtain accurate measurement results
- ladies are recommended not to use any make-up, especially mascara
- you can eat and drink (non-alcoholic beverages) as usual before the tests
- bring your national health insurance card with you so that we can prescribe you the necessary drugs
- bring your previous eyesight reports and glasses with you
In the case of online registration, the pre-operative examination is FREE OF CHARGE.
What kind of tests should you expect?
Tests are completely painless. We use the most advanced technology: Carl Zeiss and Alcon devices.
- Visual acuity measurement: a precise definition of the correction used so far Video
- Measurement of primary and secondary refractive errors: definition of the level of myopia, hyperopia and/or astigmatism. These are refractive errors that can be corrected by conventional laser treatments as well. Video
- Measurement of higher-order hidden refractive errors: by means of a wavefront analysis, carried out using an aberrometre (or ‘Eagle Eye Metre’, as nicknamed by our patients), hidden individual refractive errors can be precisely mapped. These errors can be corrected by an Eagle Eye Treatment (Sasszemkezelés®), thus a 20/20 or even better visual acuity may be obtained. Today’s cutting-edge technologies are able to ensure a vision that is better than 20/20 (normal) vision created by nature. Video
- Cornea and pupil diameter measurement: : the surface of the area to be treated may also determine which treatment is recommended. The size of are available for vision correction is relevant when the treatment is planned.
- Intra-ocular pressure (IOP) measurement: Increased intro-ocular pressure may be a first sign of glaucoma. In such cases, a full examination is recommended and laser treatment is not an option.
- Spatial vision examination: this examination helps measure the vision of both eyes together. This cannot be improved even by a laser treatment.
- Corneal topography (photokeratoscopy): the cornea is a clear membrane that covers the front of the eye; this is where light rays enter the eye. It is not completely smooth; there might be minor irregularities on its surface. After mapping the surface curvature of the cornea, these irregularities can be smoothed out by means of an Eagle Eye Treatment (Sasszemkezelés®). In addition, this examination also helps diagnose, or detect the first signs of, certain types of eye conditions that endanger the outcome of many laser eye treatments. Video
- Corneal thickness measurement: Only surface treatment (PRK, involving one laser) is recommended for those with a low corneal thickness; FEMTO is not recommended. It is therefore important to measure the thickness of the cornea
- Corneal curvature measurement (keratometry): : this will be an important aspect in planning the treatment.
- Determining the subjective refraction: is an attempt to determine, by using the conventional charts, the most suitable corrected visual acuity.
- Determining the dominant eye: this is essential especially in the case of LBV presbyopia treatments for people with reading glasses.
- Slit lamp examination: an examination of the corneal surface and epithelium designed to detect a number of conditions affecting the cornea, or their first signs. Video
- Tear production measurement: pre-treatment tear secretion determines the amount of artificial tears to be prescribed for the post-treatment recovery period. In the first few months after the treatment, tear production slows down, and therefore you will need to use artificial tears. Usually 3-6 months after the treatment, tear production returns to the normal level.
- Dilated eye examination: pupils are dilated using mydriatics. Blocking the pupillary reflexes allows the examiner to obtain further data that are important in planning the laser treatment. After dilation of the pupils, eyes will be sensitive to light, and you will experience blurry vision, especially up close, in the next 12-24 hours.
- Lens examination: it is necessary particularly to exclude the early signs of cataract.
- Fundus examination: it aims at the exclusion of certain retinal diseases that cause visual disturbances
Based on all test results, the examining specialist determines whether or not the patient is a candidate for laser treatment. They also show the degree of guaranteed vision improvement. This will be include a personalised Medical Guarantee Certificate.
What happens on the day of the treatment?
What to expect on the day of your surgery?
- prepare for a painless procedure which will take approximately 1.5-2 hours

- at your discretion, you may leave immediately or after a short rest with your companion
How to come to your laser eye surgery?
- Bring a pair of sunglasses that provide 100% UV protection (your sunglasses’ ability to block UV rays can be verified at the clinic), or you can buy a pair from the clinic’s offering
- you should not wear soft contact lenses for 4-5 days before the procedure, while semi-rigid and rigid lenses for at least 2 weeks
- ask a friend to come and pick you up at the end of your surgery
- bring with you the guarantee certificate provided to you during the pre-operative examination

What happens in the two hours spent at the Clinic?
This will a big day for you as it will change your life.
We present the steps of laser eye surgery and what will happen on the day of the treatment.
Prior to entering the operating theatre:
Do not forget to bring all the necessary documents with you: identity card, national health insurance card needed to prescribe eye drops, documents required in accordance with the payment plan selected by you, any further questions you may have.
- Arrival at the Clinic
- Reconciliation of data
- Performance of a control eye examination and comparison of the results with those obtained during the pre-operative examination
- Information about the surgery, clarification of issues
- Signing a Surgical Consent Form
- Validation of the Guarantee Certificate
- Payment of the laser treatment’s price
- Taking the sedative pills
- Entry to the preoperative care unit
- Administration of anaesthetic eye drops
- Offering your eyeglasses for a good cause (at your discretion)
In the operating theatre:
You do not have to worry about unintentionally blinking during the procedure. After numbing your eyes with the anaesthetic eye drops, your surgeon will place a special instrument in your eye which holds your eyelids open to prevent you from blinking. Patients usually do not even notice it.
You do not have to be afraid of committing any errors during your treatment. This procedure does not require any cooperation from patients besides focusing on a special fixation light in a microscope. Should any problem occur, the treatment can be interrupted, resumed or restarted at any time.
- Introduction of the surgical team
- Repeated reconciliation of data
- Assumption of a comfortable position on the surgical stretcher
- Your surgeon will continuously inform you about what is happening
- Preparation and disinfection of the surgical site
- you only have to look ahead; you cannot blink
- The Laser Engineer indicates start of the laser; countdown until the device stops
- Only in the case of FEMTO and LBV® treatments: creation of a flap with a femtosecond laser (approx. 20 seconds per eye)
- The necessary vision correction is performed by the spot scanning laser (it takes approx. 2 seconds per dioptre per eye)
- Only in the case of PRK treatments: protective contact lenses are placed in your eye which will be removed by the doctor during the post-operative check after 3 days
- You will be asked to read the time from the watch in the operating theatre; you will be able to see even the second hand
After the surgery:
After the operation, your vision will be good immediately, without the need for any devices. Some people touch their foreheads by habit to put on their non-existing glasses and then they happily conclude that they see a lot of things that they had not seen before surgery even with glasses.
- A little rest
- Information on the medical instructions both orally and in writing
- Prescription of eye drops
- Scheduling the date and time of the first post-operative check
- Issue of medical records, which should be presented to your GP so that they can issue a medical certificate needed for the sick leave
- Departure from the Clinic without glasses, if the sun is shining, wearing sunglasses with 100% UV protection
Things do after departure from the Clinic:
- Buying the prescribed eye drops
- Sleeping and resting
- Compliance with the medical instructions (see: ‘What should I pay attention to during the recovery period?’ in the following menu item)
- Should any questions or issues arise, you can contact the 24/7 OPTIK-MED hotline
What should I pay attention to during the recovery period?
What are the most important medical instructions to observe during the recovery time?
- Rest after the treatment (for 1 day after FEMTO and 5-6 days after PRK procedures)
- Apply eye drops in line with the instructions
- Keep away from places with dust or cigarette smoke for a month
- Do not expose your eyes to water for a month (saunas and steam rooms are not recommended either)
- Do not wear make-up on your eyes for 2 weeks after a PRK and 4 weeks after a FEMTO procedure
- Do not rub your eyes for a few months after the treatment
- The use of tanning beds must be strictly avoided for 3-6 months
- Outdoors, when the sun is shining, wear sunglasses providing 100% protection from UVA rays (for 2 months after a FEMTO and 6 months after a PRK procedure)
- Attend the required post-operative checks
- Should you have any questions, please call our 24/7 OPTIK-MED hotline at +36 1 250 5505
What to pay attention to after the recovery?
After your recovery, you will not have to pay attention to anything. Vaginal delivery is still possible after this treatment. All kinds of sports and exercises can be performed in the same way. Antal Kovács (Olympic champion in judo), Botond Storcz (sprint canoeist) and Norbert Schobert (fitness guru) continued working out in the same way as they did prior to their laser eye surgery.
Although the treatment virtually takes only 1-2 hours and after that you will see perfectly, you must adhere to certain rules in the next period. We summarised what medical instructions must be observed after an eye surgery.
