Intraocular Lens Implants

Selecting the lens to replace the cloudy cataractous lens or clear lens is an important part of achieving the optimal visual outcome.

There are many lens implants available and are often referred to as lifestyle lenses or premium lenses as they maybe customised to a patient's individual visual needs.

These intraocular lenses (IOL) are made of soft foldable material that are easily inserted into the once the cataract is removed. They are made of plastic or silicone materials and are permanent

Monofocal lenses

These are the most commonly used lens and offer a single zone of clear focus, usually to provide excellent distance vision. Often patients will require reading glasses for near tasks. Some patients can benefit from “monovision” where the dominant eye is corrected for distance and the non-dominant eye is corrected for near (for reading).

Multifocal lenses

Multifocal lenses are very much like varifocal glasses and are designed to divide the image into several zones using a series of circles etched into the lens usually allowing a patient to see for near, for intermediate distance and far away. There are many types available including the AcroSof ReSTOR and ReZoom lenses.

Multifocal IOL's reduce the likelihood that you will be required to wear glasses or contacts after surgery as they incorporate both distance and near powered optics into one lens which work together to provide the eye with a full range of vision. Some patients can experience ghosting, glare and haloes with these lenses.

Pseudo-accomodative lenses

These lenses are similar to multifocal lenses but are clear and do not have the disadvantage of causing ghosting, glare of haloes.
