2 piece accomodating iol
Multifocal IOLs consist of multiple zones of lens power that produce more than one focal point, allowing for enhanced vision at both near and far.Its mechanism of action is based on apodization, in which a near-dominant central area is surrounded by 12 concentric rings of decreasing height that result in diffraction of light at both distance and near.Intraocular lens implants (IOLs) are used in both refractive lens exchange and cataract surgery to replace the natural lens of the eyes and correct for refractive errors.
Your physician will discuss with you the appropriateness of these based on your individual visual needs and on your eye examination. Accommodating IOLs are also designed to provide a continuous range of vision for distance, intermediate, and near, eliminating or reducing patients’ dependence on reading glasses or bifocals.
This is made possible by the IOL’s unique design structure, which allows the lens to move back and forth as it would during natural focusing of the eye.
When viewing distant objects, the internal muscles of the eye remain in a relaxed state and maintain the lens in a position to provide perfect distance vision.
Despite the difficulties in measuring accommodation, accommodative IOLs represent the future in the attempt to successfully “cure” presbyopia.
The restoration of near vision in older individuals that have entered the presbyopic age is considered one of the major challenges in refractive surgery during the last decade.
The Re Zoom IOL is a second-generation refractive IOL, that enhanced some aspects of the Array design, such as enlargement of the second and third zones, reduction of the fourth and fifth zones and an aspheric transition between zones so that visual disturbances could be reduced.
