Sight in HD also after 40.

Refractive lens exchange

 After forty years of age, the majority of people start to experience presbyopia. This age-related condition is characterised by worsening near sight (reading) and working vision (working with a computer). In the past, the only alternative was multi-focal spectacles or using two different glasses. However, today you can undergo treatment which will provide you quality vision for all three distances with a so called refractive lens exchange (PRELEX – Presbyopic Lens Exchange).


At the VESELY I Eye Clinic, we pay great attention to the quality of specialistic care and the selection of the implants. For this reason, we offer you implants from the two highest-quality producers who are the best in the world, not only in production and quality but also in implant development.

All the implants we use in our clinic are made of soft, hydrophobic acrylate. They can be folded and therefore their implantation through minimal incisions is possible. The most modern design and the artificial intraocular lens material provide the greatest visual acuity and reduce the risk of a secondary cataract. That is why the selection of an implant is very important for overall long-term results and satisfaction of our patients.



You will first undergo a complex initial examination with the aim of gaining as much individual data as possible not only about your eyes, but also about your habits, hobbies and activities. Based on these results, our specialists will recommend you the most suitable and safest solution and further procedure for you.

Before to examination in the Centre of laser and refractive surgeries of the VESELY I Eye Clinic, you must not wear contact lenses for at least two weeks, in order to avoid distorting the results of this very sensitive examination.

The examination itself takes approximately two hours and it also includes the measurement of the visual acuity, measurement of intraocular pressure, the control of the anterior segment of the eye (cornea, iris, lens) and the fundus examination. Along with this you will undergo several soecialized examinations to help us determine the exact level of your refractive defect. For this reason, we do not recommend to come to the appointment by your own car. The effects of this examination (worsened near vision, the inability to focus) will spontaneously disappear within 3-4 hours after the examination.

Before the surgery

It is not necessary to undergo an internal pre-operative examination allowing the surgery to be carried out under local anaesthetic. A week before to surgery, it will be necessary to apply drops into the eye, which will be operated, as recommended by the doctor.

A week before the surgery we rocemmend you to take a preparation for the protection of the retina, that contains omega-3 fatty acids. You can get this preparation at our clinic at the end of your preoperative examination within the package “protection of the retina”.


Alike the cataract surgery, this treatment is pain free and lasts less than 15 minutes. You will undergo several specialised examinations which will help our specialists to calculate the exact implant that will be most suitable for you. Thanks to this implant you can enjoy your quality vision again without glasses already on the second day after the surgery.


Your stay in the eye clinic on the day of the operation will last approximately two hours. During that time we will check your condition and exclude any acute eye diseases. Then, drops will be applied to the pupil of the eye that will be operated. Surgery is carried out under local anaesthetic and is pain free. The surgery itself takes an average of 5 to 10 minutes.

The surgery itself can be done in two different ways.


In the classical procedure, the lens must be broken by an ultrasonic sonde after the surgeon performs several previous actions, such as entry cuts, capsulorexa- hole in the capsule of the lens and more.

Into the free space is then inserted an artificial intraocular lens that replaces the original lense.

FLACS- Femtosecond Laser Assisted Cataract Surgery

FLACS is a method, that is more modern, more harmless and much safer. That means a cataract surgery assisted by a femtosecond laser.

On VESELY | Eye clinic we use as the only ones in Slovakia the laser CATALYS, which was from the beginning designed specially for the cataract surgery, unlike other lasers.

Femtosecond laser can perform up to 60% of the steps of a cataract surgery. This laser divides the lens into several hundred small regular fragments that have no longer be crushed by ultrasound but they can just simply be removed. This makes the whole procedure harmless and safer.

In the case of implantation of so called multifocal or toric lenses in cataract surgery we normally use the navigation system VERION from the company Alcon. Thanks to this system we can accurately determine the optimal position of the lens in the eye, so the result of the procedure is as perfect as possible and your visual acuity as good as possible.

After the operation you will get an operational protocol and identification card of the lenses (implant). Approximately 20 minutes after the surgery you can leave the eye clinic accompanied by a close person. You will see the result of the cataract surgery immediately after the surgery.
