Who is suitable for the surgery?

Lens replacement is particularly suitable for people over 45 years, who have signs of age-related hyperopia in addition to their refractive errors (myopia, hyperopia or astigmatism). Lens replacement is also suitable for all individuals who want a permanent solution to their refractive errors. Lens replacement can be done whether you have cataracts or if the lens is still clear and shows no signs of cataracts.

What types of intraocular lenses (IOLs) are there?

Lenses differ in shape and the intended vision distances. Monofocal lenses are used to correct far-sightedness. Bifocal lenses are used to correct distance and intermediate vision or close vision, while multifocal lenses work for all distances. All common types of lenses can also be obtained as toric or cylinder lenses.

Kudos to Dr Drev and the whole team, you are doing amazing things for mankind in such a delicate part of the human body as the eyes!

I decided to have the procedure to get rid of my glasses. I felt very good during and after the surgery.

How is the surgery performed?

The lens replacement surgery is a safe, painless and short procedure for the patient. However, it requires an extremely skilled ophthalmologist, as it is a complex microsurgical procedure. The surgery is performed under local anesthesia, similar to cataract surgery. The surgeon makes a small incision, removes the lens and replaces it with a custom-made and permanent intraocular lens. After the procedure, which is performed on an outpatient basis, patients begin to regain their vision immediately, with a definitive improvement visible within a few days.

What happens during the pre-operative check-up?

Before the procedure itself, a very detailed in-depth vision examination is performed, which includes a complete diagnosis of the eyes, such as: fundus examination, intraocular pressure measurement and corneal topography.

This examination determines whether the patient is even a suitable candidate for lens replacement.

Determining the appropriate optical power
Corneal topography test and anterior segment analysis (Pentacam)
Laser analysis of individual parts of the eye (wavefront analysis - iTrace)
Laser measurement of axial length and WTW distance (IOL master 700)
Corneal analysis (Specular endothelial microscope - KONAN)
Fundus examination with OCT laser scan

In addition to high-quality equipment and facilities, the most important thing is to choose an experienced ophthalmologist who will understand your wishes as well as play an active role in the planning process of your eye surgery, advising you on which method of vision correction surgery is the most suitable choice for you.


Your eyesight is your decision, let us make it our concern.


Does the optical power still change after lens replacement surgery?

No, the optical power remains constant after surgery.


Can the eye reject the lens?

No, because the lens is made of a biocompatible material that is similar in elasticity to a natural lens.


Can the lens be replaced if the optical power is not fully corrected after the surgery?

The lens can always be replaced.


Are there any limitations to the procedure regarding refractive errors?

Every refractive error can be corrected, but various eye diseases can limit the possibility of lens replacement surgery. If the eyes are healthy, any refractive error can be solved.


Can the procedure be done on both eyes?

IOL implantation is intended for both eyes. In case the optical power in one eye is 0.00 dioptres, the surgery is performed on one eye only.


What are the most common complications?

Inflammation may occur, which is treated with antibiotic drops, but drug allergies, increased intraocular pressure and deviation of optical power are also possible, which can be resolved with additional laser surgery.


Can the lens cause glare?

When driving at night, the glare may last longer. However, it should be noted that the ZEISS lens causes significantly less glare than IOLs from other manufacturers.


I know someone who has had this surgery, but now he can't see very well at intermediate distance. Why?

In addition to the trifocal IOLs used at the VIDIM Eye Centre, there are also bifocal lenses of slightly inferior quality that have been used in the past.


Does the lens help with colour blindness?

No, the lens does not help with colour blindness.


Is the surgery possible if I have had laser correction in the past?

The calculation for IOL is much more complex after laser correction, and the surgery itself is also more difficult and complex. Therefore, IOL insertion is not always feasible after laser surgery, however, a qualified ophthalmologist can determine if the lens replacement is possible or not.
