Trifocal lenses are a good solution for anybody who wishes to live without glasses following cataract surgery.
The trifocal lens allows - after a successful intervention - for a sharp image at any distance. This lens even allows corneal irregularities to be corrected.
It is the technologically most advanced intraocular lens, which additionally features a blue light filter.
This means you no longer need glasses* and will be able to see clearly both near (e.g. for reading) at intermediate distance (e.g. for working on your computer or eating) and far.
Therefore, the trifocal lens is an elegant alternative to progressive glasses (Varilux glasses). Trifocal lenses do have minor drawbacks, e.g. a slight reduction in contrasts and a slight increase in pools of light around light sources at night (so-called halo effect).
* According to studies, 90 – 95% of the patients require no glasses at all. 5 – 10% of the patients occasionally still need glasses, e.g. to read small print up close.

If, despite all measurements and preliminary examinations, there is still a relevant refractive error (e.g. still slight myopia) after the surgery, this can be corrected. For example, an additional intraocular lens can be implanted in front of the first intraocular lens. In this case, the Vista Alpina eye center assumes all costs associated with the correction.
For the majority of patients with trifocal artificial lenses, the benefits of living without glasses outweigh the little and sometimes only temporary impairments. Your Vista Alpina ophthalmologist will gladly discuss the advantages and disadvantages in detail during a personal consultation appointment.

Clinical studies
Dr. Vandekerckhove regularly conducts clinical studies on refractive premium lenses and holds lectures on toric and multi-focal artificial lenses both domestically and abroad. He is also involved in developing new toric and multi-focal artificial lenses. Every year he performs around 1800 cataract surgeries with up to 400 refractive premium lenses.
