Cataracts
Cataracts always occur as a result of presbyopia. New lens fibers form, while the old cells in the center of the lens become cloudy. This eventually leads to a lack of transparency, which is ultimately responsible for the deterioration in vision. Cataract patients most frequently complain of problems seeing in the dark. They then feel severely dazzled by light. Contrast vision also deteriorates and reading often causes great strain, resulting in watery eyes or even headaches.
In the best hands
Dr. Kretz is of course aware that cataract surgery is a very sensitive subject for most patients - after all, their eyesight is at stake. They should have the security and certainty of being in the experienced hands of an expert. Dr. Kretz has performed over 10,000 cataract operations in the last 3 years.
As an internationally recognized specialist in the treatment of cataracts, he has published over 100 scientific papers on this topic and is regularly invited as an expert to specialist events worldwide.
Colors & contrasts
"I have the feeling that the colors are getting weaker, fading and the contrasts too."
Reading
"Seeing in the dark causes me a lot of problems."
Darkness
"Reading becomes more difficult and tiring. The strain also makes my eyes start to hurt and water."
Being severely dazzled by light
"I feel very dazzled by light in the dark."
Claude Monet and cataracts
At the age of 72, Monet began to feel the effects of cataracts. Above all, the altered color perception caused him so much trouble that from then on he meticulously arranged his paint tubes and used the labels as a guide when choosing colors. He also gradually lost his visual acuity. Both are clearly reflected in his paintings from this period.
While Monet was working on the Water Lilies series (which also includes the example paintings of the Japanese Bridge), he went blind in his right eye. A few years later, the sight in his left eye also became so poor that he ultimately decided to have an operation, which was successful.
"Monet is only one eye, but what an eye."
Paul Cézanne
The agony of choice
You will discuss the individual selection of the optimal intraocular lens in detail with Dr. Kretz. You can choose from a wide variety of models for cataract surgery. Depending on the results of your eye diagnostics and your individual needs at work, in everyday life and for leisure, you will choose the right model together.
Patients with statutory health insurance who undergo cataract surgery are entitled to be fitted with a free eye lens ("standard lens"). The implants covered by statutory health insurance are usually simple, monofocal spherical single-vision lenses.
The standard operation does not lead to independence from glasses in everyday life, but merely to an improvement in the quality of vision. If you opt for this option, you will still need to wear near and distance glasses or varifocals after the operation.
As part of our Lite package, we implant aspherical, aberration-neutral lenses. These are characterized above all by a uniform imaging quality over the entire lens optics. This means that the refractive power of the lens is largely independent of the pupil. For you as a patient, this results in a significantly better image quality with better contrast vision and a lower risk of glare, especially when driving at night. The Lite package is not intended to make you independent of glasses, but merely to improve the quality of vision.
Lite package from €25/month for a 22-month term (total costs from €550.14 per eye as an additional payment to the costs covered by statutory health insurance)
If you wish to be free of glasses for distance or near vision, you can choose the Economy package. In this case, vision correction is possible for one distance (far or near). In order to achieve the best possible vision at the desired distance, we use aspherical, aberration-correcting intraocular lenses. If you are found to have astigmatism during the preliminary examination, this can also be corrected as part of the economy package: with a toric lens. This also has aspherical optics and can also compensate for the existing astigmatism up to a certain degree (for high astigmatism, see Smart package). With the Economy lenses, the precise correction of the visual defect and the aspherical optics ensure high image quality and good contrast vision, especially in dark lighting conditions (e.g. when driving at night). If you opt for this package, you will have sharp vision for the desired distance (usually distance, in some cases near, e.g. very high myopia), for all other distances such as reading and/or PC distance you will still need glasses.
Economy package distance: wearing near glasses
Economy package near: Wear distance glasses
In the economy package, you will also receive retinal protection during the operation. This is administered in the form of a medication into the vitreous body of the eye and reduces the risk of oedema in the macular area.
Economy distance/proximity package from €31.25/month for 24 months (total costs from €750.12 per eye as an additional payment to the costs covered by statutory health insurance)
In order to achieve the best possible individual correction for distance vision, we offer you the Smart Distance Package. The lens implanted as part of this package not only corrects your visual defect for distance vision, including any existing astigmatism, but also has a "depth of field effect" (Mono-EDoF IOL). This means that the lens implant - like a camera via the aperture - produces a particularly clear sharpness at a distance. This is achieved using various special surface designs of the intraocular lens. The depth of focus also ensures sharp vision from far to medium distances, so that sometimes even computer work is possible without wearing glasses. For optimal correction of the near and intermediate range, you will still need a visual aid after the operation. Optical side effects (e.g. glare) are comparable to those of a normal standard lens.
The Smart package also includes all lenses for correcting high corneal curvatures (where technically possible), which cannot be covered by the Economy package.
The Smart package also includes retinal protection during the operation. This is administered in the form of a medication into the vitreous body of the eye and reduces the risk of oedema in the macular area.
SMART package from €39.58/month for a 24-month term (total costs from €950 per eye as an additional payment to the costs covered by statutory health insurance)
Media devices (such as laptops, computers, tablets, etc.) are becoming increasingly important not only in everyday working life, but also at home. This also increases the demands on vision in precisely these areas. The business package is primarily aimed at very active patients who want to see clearly from distance to intermediate vision or from intermediate to near vision without glasses or contact lenses. The lens implants not only consist of a smooth surface with a constant strength, but also have at least two zones with different strengths or active principles for sharp vision. This not only compensates for the visual defect for distance vision, but there is also an additional power ("addition") for the intermediate range, which allows you to see at medium distances - for example at the computer/laptop. With the lenses in the business package, there is a smooth transition between the areas, so that seamless vision is possible from the distance to the intermediate range. Experience has shown that the implants produce little disturbing glare, so that good night vision is possible. With this lens package, you already achieve a high degree of independence from glasses. However, you will still need glasses for the uncorrected distance (near or far).
The "second" prescription can be created using different lens optics. Your treating ophthalmologist will select the most suitable intraocular lens for your eye. We use implants with different principles of action for the Business Package:
Rotationally asymmetric intraocular lenses - This is a "bifocal" optic in which a near segment is located in the aspheric lens, allowing a second power to strengthen both the intermediate range and a depth-of-field effect.
Sinusoidal lenses - This type of intraocular lens has a ring-shaped pattern with soft edges on the surface, through which the incident light can be used as effectively as possible while minimizing optical interference (glare). The comparatively smooth surface design creates seamless vision from the distance to the intermediate range.
Wavefront-optimized lenses - On the surface of these lenses there is a small "plateau" with a soft transition edge and a slight change in curvature. The combination of these two elements (plateau and change in curvature) enables seamless vision between the distance and intermediate ranges, creating the desired extended range of vision.
In the business package, you will also receive retinal protection during the operation. This is administered in the form of a medication into the vitreous body of the eye and reduces the risk of oedema in the macular area.
Business package from €52/month for 24 months (total costs from €1250.13 per eye as an additional payment on top of the costs covered by statutory health insurance)
Our First Class package aims to achieve maximum independence from glasses in everyday life. Depending on the demands you place on your everyday life, you can achieve 95 - 98 % independence from glasses. The selection of the right intraocular lens optics and their combinations is particularly important here. Precise Vision ophthalmologists work together with all well-known lens manufacturers. Depending on your individual visual requirements and the results of your detailed preliminary examination, we will select the right lenses together with you. For the most part, diffractive intraocular lenses (IOLs) are used here. These are characterized by a special surface design that has several "power additions". This results in sharp vision at near, intermediate and far distances.
The various power additions are recognizable on the lens as a fine ring structure. The light can refract at the edges of these rings and thus fan out into different "strengths". This means that not just one area, but several areas are in focus.
This principle is essential for optimum light distribution, but causes optical side effects in the form of glare ("halo & glare"). These are subjectively more noticeable, especially at the beginning, but are also necessary to ensure that the lenses function correctly in your eyes. As part of the neuroadaptation process, your brain learns to deal with this and you get used to the new visual impression. Despite side effects at different distances, sharp vision is usually possible without any problems in the first few days after the operation. The implantation of these lenses comes closest to the natural visual impression and independence from glasses can be achieved that is very suitable for everyday use.
First Class package from €67.06/month for 24 months (total costs from €1609.52 per eye as an additional payment to the costs covered by statutory health insurance)
As an alternative to our first-class package, we offer you the option of so-called duet implantation. This is a procedure in which two intraocular lenses are implanted in the eye. A primary lens is inserted into the capsular bag as normal to correct distance vision, so that - as with the economy package - independence from glasses is achieved for distance vision. In the next surgical step, an additional lens is placed in the ciliary sulcus, i.e. between the iris and the primary lens. This additional lens contains the presbyopia-correcting, diffractive optics. As with the implants in the classic first-class package, there is a ring-shaped design on the lens surface that creates additional power to compensate for intermediate and near vision.
The advantage of the Duett procedure is its reversibility. This means that if the optical side effects are incompatible, the second, additional Duett lens can simply be removed again in a second, minor procedure. In this case, only the primary lens remains in the eye, making the patient independent of glasses for distance vision.
You will also receive retinal protection in the First Duett package during the operation. This is administered in the form of a medication into the vitreous body of the eye and reduces the risk of oedema in the macula area.

The path to the future
In addition to applied ophthalmology, Dr. med. Florian Kretz (FEBO) also regularly works in research in order to advance this in the field of ophthalmology and to be able to treat his patients with the most innovative and latest methods. The Precise Vision ophthalmologists' locations are renowned study centers whose research results and observational studies have received international attention. Depending on your clinical picture, you may have the opportunity to take part in such a study if you seek treatment from them. You would not only support current research, but also benefit from a potentially improved and more individualized treatment method.
