Multifocal lenses-trifocal lenses-Turkey Istanbul Antalya Izmir
Similar to cataract surgery, the natural lens of the eye is surgically removed and replaced with an artificial intraocular lens (IOL) in the same location.
With the implantation of a multifocal intraocular lens, patients opt for a high-end technological product offering a wide range of possibilities. The human eye is, by nature, a highly developed sensory organ with almost perfect adaptation to all everyday conditions and demands – until natural age-related long-sightedness occurs and the limits of near vision become irreversibly noticeable. The desire for youthful vision at both near and far distances can best be fulfilled at the site of the natural eye lens. More than 80 per cent of patients fitted with a multifocal intraocular lens no longer require optical aids and are able to carry out their professional and private activities while living without glasses.
Multifocal lenses
What is vision like with a multifocal implant?
Imagine a calm pond and throwing a stone into the water. You will notice that several concentric ripples form around the point of impact. Similar to this harmonious image, the structure of a multifocal lens is designed. Nine or twelve rings allow reading at distances of 30 cm or 40 cm, which corresponds to most reading distances, while the remaining optical distribution on the lens surface serves good distance vision. The concentric design of the lens optics allows two visual impressions from the eyes to be superimposed into a single overall image. This overlapping blur may be noticeable at first. The fact that our brain has learned from a young age to retouch certain blurs is what makes this principle function in the first place.
Consideration of vision in daylight and at night
The more different optical elements light has to pass through, the greater the loss that results directly from this. The same principle can be applied to different focal planes. The fine, concentric ring steps regulate the incidence of light (energy distribution) and the transition in favour of the individual visual zones. At night or at dusk, there is less light available. The pupils (iris aperture) dilate so that, despite the reduced light, enough information reaches the retina and vision in darkness is made possible. The artificial multifocal lens is designed so that, with a normally dilated pupil of around 2–3 mm in diameter, there is sufficient light stimulation for both distance and near focusing to function successfully. This makes it possible to read comfortably and see into the distance during the day. With widely dilated pupils (at night or in low light), the light is used for distance vision. In everyday life, this means that in poor lighting conditions, near reading becomes more strenuous, but, on the other hand, disturbing light sources such as headlights or traffic signals appear less intrusive. For daily use, this means: good lighting improves reading quality.
When is the right time for a multifocal implant?
In order for the advantages of a multifocal lens to be used to full benefit, the eye should already be in a state of presbyopia. This is certainly the case from around the age of 50. In addition, by this time the eye has already undergone important physiological changes, which are favourable with regard to surgery on the eye’s own natural lens.
Choosing a multifocal lens
We have not yet succeeded in copying nature in all its perfection. A multifocal lens represents a very good compromise. A thorough preliminary examination, the subsequent consultation, understanding your expectations, and providing guidance and support after the operation are essential prerequisites for success and satisfaction with your newly gained vision for both distance and near. Give yourself and your new vision a few months to meet your expectations and to adapt to the new visual conditions.
Femto Laser Support
Thanks to new technological developments, a new method is now available. In this new treatment procedure, the small access to the eye is created using a femtosecond laser. This is followed by a contact-free fragmentation of the natural lens. The lens prepared in this way can be removed very easily and in a particularly tissue-friendly manner. The laser-assisted treatment ensures maximum safety and the highest level of precision.
