AGE-RELATED DIOPTER CORRECTION
During every cataract surgery, an intraocular lens is implanted which replaces the patient’s blurred lenses, i.e. the cataract. There are a number of different types of intraocular lenses that can be implanted in the eye during the cataract surgery.
A choice of optimum lens for each patient depends on the health of the eye and the patient’s wish. Classic intraocular lenses are monofocal lenses, which, as the name suggests, have a single focus and enable the patient, after the surgery, to see well at the distance without the glasses, but has to wear the reading glasses (or vice versa, if the patient wishes so). If, before the surgery, the patient had astigmatism (a dioptric defect of the eye which is a consequence of the deviation from spherical curvature of the cornea) or if astigmatism was induced by the surgery, after the surgery the patient will have to wear both distance and reading glasses. Standard monofocal lenses do not solve the problem of nearsightedness or astigmatism.
With the progress of the cataract surgery technology, more modern intraocular lenses developed too; on the other hand, there are more and more patients who, after this surgery, want to have good vision at all distances without wearing the glasses.
Multifocal lenses have several focuses and enable the patients who have undergone the cataract surgery good vision at different distances without wearing glasses. They are the most modern intraocular lenses. Most multifocal lenses are bifocal, i.e. they provide good vision both at distance and up close. Vision at a medium distance (80-100 cm) is somewhat worse compared to the vision far away and up close. The examples of bifocal multifocal lenses include: Tecnis (AMO); AT LISA (Carl Zeiss Meditec); AcrySof IQ ReSTOR (Alcon); M-flex (Rayner); Lentis Mplus (Oculentis); ReZoom (AMO).
The latest generation of multifocal lenses includes trifocal lenses which, besides good vision at distance and up close, also provide good vision at medium distance, which is especially important for the patients who spend a lot of time working at the computer. Trifocal lenses imitate the natural accommodation enabling the patient good vision at all distances (distance, proximity and medium distance), thus allowing him to be fully independent of the glasses. The examples of trifocal multifocal lenses include: AT LISA tri (Carl Zeiss Meditec) and FineVision trifocal (Physiol) and Symfony (AMO).
Multifocal (bifocal and trifocal) intraocular lenses may be designed as toric lenses too, which means that besides standard diopter they can correct astigmatism too.
Besides the cataract patients, multifocal lenses may be implanted to the patients who do not have cataract, but wish to be rid of distance or reading glasses. The candidates for such an operation are persons older than 45 who, besides wearing glasses, do not have other eye diseases. After the surgery, the patients who have been implanted multifocal lenses, can see the light circles around the light source in the dark (haloes) or glares at a strong light which are caused by lens design; however these problems are reduced with time and fully disappear. A surgeon’s experience, modern technology and precise calculation of the strength of the lens that is implanted during the surgery are the most important factors to achieve good post-surgery results and the patient’s satisfaction.
