Blended vision according to the Duesseldorf formula - for cataracts and presbyopia

(image: blended-vision-4-en-thumb.png link: blended-vision-4-en.svg class: align-right lightbox alt: Grafik zu Überblendvisus) Humans are all individuals: Therefore, there is not any "best" lens that fits everyone. According to the "Duesseldorf formula" developed by Dr. Breyer for treatment of presbyopia, we combine segmental premium lenses with varying refractive powers according to your personal visual preferences to provide you with maximum independence from your glasses. What is special about this procedure is that the lenses' vision fields complement and overlap each other to provide you with as natural a vision as possible. "Blending" is a term frequently used in photography and film for combining two images with each other. The same principle is used for visual acuity: One eye has clear vision at large distances, the other at near distances. In addition, both can see the middle "blended field" clearly. So far, this was achieved with uniform refractive powers of 0.0 and -1.5 dpt in a laser procedure. With the Düsseldorf formula, you have a choice with regard to the fields of visual acuity in which you will have clear vision. ### Important advantages of blended vision Blended vision has the following advantages over conventional multifocal lenses and a monovision treatment:
  • Therapy tailored to you personally by individual lens combinations
  • Good stereoscopic vision
  • Less bothersome light phenomena
  • Better contrast vision

The company Oculentis was so convinced by this that it is even recommending our "Duesseldorf formula" with its premium lenses specifically designed for this procedure to other eye surgeons.

From laser blended vision to blended vision according to the Düsseldorf formula

  • 2013: The Inspiration. During the Zeiss symposium within the scope of APACRS in Singapore, Dan Reinstein presents Presbyond laser blended vision: An excimer laser treatment (Presbyond) in which one eye is optimized for distance vision (0.0 dpt) and the other for near vision (-1.5 dpt). In addition, a special ablation profile achieves a higher depth of focus (by means of spherical aberrations). Since the target refraction of both eyes only differs by 1.5 dpt, a blended field is created at a medium distance. This principle inspired Dr. Breyer to transfer it to intraocular lenses.
  • 2014: Dr. Breyer presents his concept of blended vision with segmental MIOL to the international congress of the Presbyopia Society (ISOP) and the European Society of Cataract and Refractive Surgeons (ESCRS) in London.
  • 2015: In Barcelona, we present our clinically significant scientific data proving this idea to ISOP and ESCRS.
  • 2016: Dr. Breyer not only introduces blended vision with new data at our innovation symposium in Düsseldorf but also at the global congress of ophthalmologists in Guadalajara (Mexico), in Athens (ESCRS), in Chinese Taipei (APAO), in Nuremberg (DOC) and in Rome in the elitist circle of the American-European Ophthalmologist Surgeons (AECOS).
  • September 2016: Within the scope of its international research congress in Copenhagen, the European Society of Cataract and Refractive Surgeons (ESCRS) awards a prize in the "innovation" category to the scientific video on blended vision by Dr. Breyer and his colleagues.

What’s precious to you belongs in good hands

If you are interested in having the best vision without glasses, please feel free to make an appointment with Dr. Breyer for a non-binding individual consultation or preliminary examination. You can make an appointment by phone, e-mail or online appointment. We are also happy to call you back. We are looking forward to your message.

The patient-doctor discussion is the basis for custom-made blended vision

To enable us to select the right lenses, we set great store by an in-depth patient-doctor discussion in which we will inquire about your visual habits in detail. This includes questions about your occupation, hobbies and other activities or habits which can shed light on which areas of vision are a priority for you and in which you would be willing to make a compromise; these are important to reduce side-effects to the lowest extent possible. For example, it is very important whether you are driving a car at night frequently or rarely since the tolerance for glares usually depends on this. If you are on the road at night frequently, you are sensitive to glares. In most cases, athletes prefer having sharp distance vision while people doing a lot of near work set the greatest store by near vision.

We use our scientific experience with premium lenses and the results of the patient-doctor discussion to derive a lens recommendation from them. We will then explain to you the anticipated vision result after the surgery using visual aids such as e.g. illustrations of glare effects and posters with fonts in different sizes to realistically inform you in advance about what you can expect once your brain has become adjusted to the new visual impression. This adjustment stage (neural adaption) differs between different persons and may take up to around three months.

Individualized patient care with different variants of blended vision – The Duesseldorf Formula

Dr. Breyer has presented blended vision according to the Düsseldorf formula with a video on numerous international professional congresses. In September 2016, it was even awarded a prize in the "innovation" category at the European Congress of Refractive and Cataract Surgeons. It describes the scientific background and data collection, how it works, how surgery is performed and how to inform the patient about the procedure. Please take a look.

Patient reviews

“Düsseldorf formula with an impressive result, even better than expected!”

„High myopia (approx. -9/-8) and cataract. After my daily life and driving had become more and more difficult, I had to come to grips with an operation. – Dr. Breyer was able to convey a great amount of calmness, explained everything and answered all questions. Part of the information and examinations were provided by staff members, all of whom I experienced as very warm and friendly. Yes, there is a lot going on in the practice, everyone is very busy. However, the waiting time is reasonable. As an anxious person, I may have been a bit annoying, and today I’m just happy that I took all of Dr. Breyer’s advice: Surgery according to the Düsseldorf formula, with a femtosecond laser, personalized premium lenses, no general anesthesia, operation of both eyes with one day between the procedures.

Just half a year later, and I’m sitting here with a bright smile on my face and without glasses, and I can see perfectly! – I struggled with the Düsseldorf formula in the beginning. I wanted the best for my eyes but nothing untested. To put it in laymen’s terms, it is not about the lenses but about the eyes supporting each other. And that works better than I expected: Before the operation, I was told I needed glasses for small print after the operation. However, I actually read books/newspapers/on my computer without glasses. Very small print is more relaxed with +1 reading glasses. Distance is no problem at all. I only don’t like driving my car in the dark when it’s raining, even though the double vision I had before is gone. (...) Heartfelt THANKS to Dr. Breyer for his research, work and friendly advice and to the whole team for their precision and friendly support
