Symptoms: Blurred vision at close range, texts have to be held further away, headaches or tiredness when reading.
Many patients come to us because they can no longer tolerate the side effects of their expensive progressive glasses. Presbyopia suddenly dictates your posture:
We don’t prescribe stronger glasses that you have to “get used to.” We reconstruct the optical dynamics directly within your eye.
The treatment goal is freedom from glasses. The path there depends decisively on age and anatomy. We offer you the most modern procedures in Europe in 3 stages:
Your own lens is stiffer but still completely clear. Here, we work on the corneal surface:
Option A: PresbyMAX (Laser Blended Vision)
Option B: The game changer “Allotex TransForm” (100% biocompatible & reversible)
The lens is rigid and may begin to cloud microscopically. A laser on the cornea would not be sustainable here. We rely on refractive lens exchange (RLE).
For lens exchange, we are independent of manufacturers and select the lens from the global market that fits you perfectly:
Your eye provides a new optical signal from day one. Your brain needs time to process these new images perfectly. This neurological learning process (neuroadaptation) takes between 3 and 6 months.
We do not hide medical facts. Months or years after a lens exchange, the body’s own capsule can cloud slightly ( Afterstar). This is normal. The solution? We “polish” the capsule in our practice in a painless, 60-second treatment with the YAG laser. Afterwards, your vision is immediately and forever crystal clear again.
| Method | Ideal for | Special feature & technology | Limitations |
| Allotex TransForm | Age 45-55 (good distance vision) | 100% natural corneal inlay. Reversible! No plastic. | Eye must be largely free of refractive errors (emmetropic) for distance. |
| PresbyMAX (Laser) | Age approx. 45–55 years | Increases the corneal depth of field. Can be simulated in advance! | Lens continues to age. |
| Lens exchange (EDOF) | Age 55+ (night drivers) | Seamless vision (distance to PC). No nocturnal halos. | Reading glasses may be needed for tiny print. |
| Lens exchange (Trifocal) | Age 55+ (reading focus) | Replaces the natural lens. Glasses-free at all distances. | Slight light rings (halos) possible during night driving. |

“The treatment of presbyopia is the supreme discipline of eye surgery. Today, we offer technologies that were unthinkable a few years ago – from reversible biological Allotex implants to robot-assisted femto lens exchange. My task is to work with you to find out if your brain, your anatomy, and your lifestyle harmonize perfectly with this new optics. Absolute transparency is the foundation for your lifelong satisfaction.”

Progressive lenses have narrow vision zones. To see clearly, you have to raise or lower your head unnaturally. This leads to cervical spine syndrome (neck pain) and a dangerous “swimming effect” when climbing stairs.
It is a revolutionary, microscopic inlay for the cornea that restores near vision. Unlike earlier implants, Allotex consists of 100% sterile, natural human corneal collagen (no plastic). It is extremely biocompatible, and the eye accepts it as its own tissue.
Yes, that is the biggest advantage. Should your eyes change significantly over the years or if you later wish for a lens exchange, the wafer-thin Allotex inlay can be removed easily and without residue in a short procedure.
With PresbyMAX, we can model the cornea so that the depth of field increases massively. However, since the natural lens continues to age, the laser effect is usually excellent for about 5 to 10 years. Refractive lens exchange is permanent (lifelong).
In old-fashioned monovision, one eye is strictly lasered for distance and one for near vision (often leading to headaches). PresbyMAX creates an extended depth of field so that both eyes share a common intermediate zone. The brain tolerates this excellently.
Yes! We simulate the optical profile of PresbyMAX exactly during the preliminary examination with special contact lenses. You test the visual sensation in everyday life before we even turn on the laser.
Surgically: Yes. The difference lies in the material: in standard insurance-covered surgery, a standard lens is used. In refractive lens exchange, we use high-tech premium lenses (EDOF/trifocal).
In this premium version, we do not use a manual scalpel cut. A femtosecond laser opens the cornea and the lens capsule with micrometer accuracy and fragments the old lens. This massively increases precision.
No. Since your natural lens is replaced by an artificial lens made of biocompatible acrylate, you can never develop cataracts again for the rest of your life.
Months or years after the lens exchange, the capsule in which the new lens sits can cloud over (posterior capsule opacification). We “polish” this capsule in the practice with a YAG laser in 60 seconds, painlessly. After that, vision is clear forever.
Vision is often very good as early as the next day. But your brain must learn to filter the new optical signals correctly. This process of “neuroadaptation” takes 3 to 6 months.
Multifocal lenses break light into different rings. At night, stray light can occur at these rings (halos around headlights). The brain usually fades out these effects after a few months.
Trifocal lenses have 3 fixed focal points. EDOF lenses (Extended Depth of Focus) offer seamless vision from distance to PC with almost zero halos, but may still require reading glasses for extremely small print.
No. The lens is placed exactly in the spot where your natural lens was previously located. There are no pain nerves there.
No. Your eyes are numbed locally with drops. You only feel a slight pressure, but no pain at all.
Yes. General anesthesia is not necessary and would only carry risks. You can receive a sedative upon request.
The PresbyMAX laser takes a few seconds per eye. Allotex implantation or a lens exchange takes a relaxed 10 to 15 minutes in the operating room.
During lasering, our 7D eye tracker detects micro-movements and stops immediately. During lens exchange and Allotex implantation, the surgeon guides the instruments so gently that movements are safely compensated.
Recovery is very fast. Most patients can return to work after 2 to 3 days.
Light jogging is allowed again after 3-4 days. Swimming (spa visits, Old Danube) and sauna are strictly forbidden for 3 weeks (risk of infection).
Only when the ophthalmologist determines sufficient visual acuity during the follow-up check (usually the next day).
Please completely avoid eye makeup for at least one week.
PresbyMAX starts at approx. 1,500 to 2,000 euros per eye. Allotex implants and premium lens exchange (EDOF/trifocal) are higher due to material costs (often 3,000 to 4,500 euros per eye).
No. Public health insurance only pays for a standard lens in cases of advanced cataracts. Freedom from glasses is a private service. However, you can deduct the costs for tax purposes (“extraordinary burden”).
Yes, in cooperation with our financing partners, we offer convenient installment payments.
Since the tear film is the first refractive layer of the eye, it must be intact for premium lenses or Allotex to function perfectly. We treat your tear film specifically in advance.
Premium safety tolerates no haste. Optical measurement (IOL Master), topography (Pentacam), contact lens simulation, and the consultation with Dr. Derhartunian require time for a perfect result.
