Implantable premium lenses: The different types and procedures offered by DOmed
As of now, the DOmed eye specialists can offer premium lenses in accordance with the co-payment agreement, resulting in huge savings for the patient. The surgical ophthalmologists at DOmed not only fulfil the conditions of participation set by the agreement between health insurers and the BDOC (Federal Association of Ophthalmic Surgeons), but exceed the conditions considerably in many areas.
Aspherical lenses are used to improve contrast vision. These lenses are better able to display images, as the asphericity of the lenses reduces the eye’s aberration (spherical aberration) (all the light rays are focused at one point).
Multifocal intraocular lenses (mIOL)
Multifocal lenses have several focus points. There are two main focal points – one for distant objects and one for close-by objects. They are composed of several rings with different refractive powers. Distribution of the incident light onto several focal points allows sharp vision in all directions. Often, glasses become completely unnecessary after the operation.
When are artificial multifocal lenses suitable/unsuitable?
Artificial multifocal lenses can be used with the following indications:
- Patients from the ages of 45 or 50 when presbyopia has set in or is imminent
- Patients who cannot be treated with LASIK due to severe visual defects
- Patients with cataracts who require an artificial lens
Those not suited for artificial multifocal lenses are:
- Patients with chronic progressive eye conditions (e.g. Glaucoma, macular degeneration, retinal diseases)
- Patients under the age of 18
The anatomy of the eye or extreme astigmatism may also be an exclusion criterion. A thorough preliminary examination is important for the success of the operation and subsequent optimal vision.
Tecnis symfony allows sharp vision at various distances by extending the depth of field.
Normal multifocal lenses have various refractive zones which allow vision at short or long distances. The incident light is thereby distributed between various focal points.The brain chooses the depiction on the retina which matches the situation.
The Tecnis Symfony, on the other hand, allows life without glasses with just one image.
This lens combines two technologies:
The optical design enables expansion of the depth of field in various stages. At the same time, contrast vision is increased by the correction of light rays of various wavelengths.
