| --- | --- | --- | --- | --- |
| **Material** | Hydrophobic Acrylic | Acrylic | Biosil, a biocompatible third-generation silicone. | Acrylic |
| **Design* ** **See chart below** | Diffractive/Aspheric Multifocal based on the optical principal of apodization* | Diffractive/Aspheric Multifocal -  Aspheric front surface and a diffractive  posterior surface for near and distance images | Accommodating lens* with new aspheric design specific to AO version | Zonal Refractive Multifocal |
| **Enchancements** | UV blocker* with chromophores* | -UV blocker -Chromatic aberration correction* | No UV blocker | UV blocker |

 

| **Designs** | **Advantages** | **Disadvantages** | **Examples** |
| --- | --- | --- | --- |
| **Zonal Refractive Multifocal** | Creates several simultaneous images, allows for viewing objects at all distances | Undesirable visual aberrations - including night glare, halos, and starburst | ReZoom |
| **Diffractive/ Aspheric Multifocal** | -They compensate for spherical abberation and improve visual quality in most patients -Generate two distinct images, one for distance and one for near | Reduced intermediate vision | AcrySof ReStor, Tecnic Multifocal |
| **Accommodating IOLs** | -Simulates the natural accommodation process by allowing the IOL to move based on ocular muscle contraction, much like the natural lens did before cataract formation and removal -Typically provide better distance vision compared to multifocals.  | Reduced near vision that often requires the use of reading glasses to improve reading at near. | Crystalens HD, Crystalens AO |

## Glossary of Terms for Multifocal Lens Implants

|   |   |
| --- | --- |
| **Apodized** | A series of graduated steps that result in diffraction of light at both distance and near |
| **Accommodation** | The ability of the eye's natural lens to change shape to focus on objects at  various distances |
| **Accommodating lens ** | As with the natural lens, an accommodating lens moves and flexes, in response to ciliary muscle contractions in the eye. These contractions drive forward movements of the lens so the eye can maintain a clear image as it focuses on near, intermediate and far objects. (Bausch + Lomb) |
| **Cataract** | A "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered, resulting in blurred or defocused vision. |
| **Chromophores** | Material added to IOLs to increase absorption of even more of the potentially harmful visible light in the violet and blue spectrum. |
| **Halos** | A circular flare or hazy ring that may appear around a headlight or other light source. |
| **Intraocular lenses (IOLs)** | Implantable devices that replace the natural lens in the human eye. |
| **Spherical Abberations** | An irregularity in the shape of the lens. As the eye ages, the lens gets thicker and rounder, causing image quality to deteriorate. Often associated with loss of contrast sensitivity and poor night vision. |
| **UV blocker** | Ultraviolet (UV) absorber to prevent excessive exposure of UV light to the retina |
