Multifocal lens: the comfort of sharp vision at any distance
The multifocal lens, also called multifocal, is included in the PREMIUM group lenses. Thanks to its design, the multifocal lens allows the patient to see sharply at any distance (near, far and intermediate distances), which is due to the fact that it creates several focuses of focusing light.
In practice, this means that a patient who has a multifocal lens implanted does not need glasses.
In this segment of lenses you will also find multifocal toric lenses (they eliminate astigmatism, provide sharp vision for distance, near and intermediate distances).
Multifocal lenses have a unique design, taking advantage of our brain’s ability to so-called neuroadaptation (it takes an average of one to three months, and even longer in some patients).
They provide excellent vision quality and natural contrast sensitivity in both nearsighted and farsighted patients, as well as those with astigmatism.
The performance of multifocal lenses is very similar to progressive lenses used in spectacle vision correction.
Modern multifocal lenses used in cataract surgery make it possible not only to get rid of the cloudy own lens, but also to correct a co-occurring visual defect: for example, myopia or astigmatism, as well as presbyopia.
Subsequent generations of modern multifocal lenses began to enter widespread use in the late 20th century. At that time, new technologies were applied in lens design, using the phenomena of refraction (refraction) of light, known in optical physics, then – diffraction (dispersion) of light, rerfractive-diffractive (pseudo-accommodative), and finally a lens with a design that allows to change its position in the eyeball, that is, an accommodative lens. Everything you want to know about them can be found here.
Current intraocular lenses are soft, generally constructed of hydrogel, silicone or acrylic. Particularly convenient for use are lenses made of retractable silicone, which are placed in the eye through a two-millimeter incision.
At the target site, the lens develops and lays down as intended, taking its proper shape. The minimal surgical wound heals very quickly.
Multifocal lenses are not covered by NHF reimbursement.
