Clarivu involves your consultant removing the natural lens from the eye and replacing it permanently with a clear technically advanced Intra Ocular Lens (IOL), measured to give the highest quality of vision.

The new lens corrects your prescription, providing the additional focusing power previously provided by glasses or contact lenses for both distance and close up.

What is an Intra Ocular Lens?

An Intra Ocular lens (IOL) is the artificial lens surgeons implant to replace the eye’s crystalline lens.

The main job of the IOL is to focus light onto the back of the eye just as a natural, healthy eye lens would.

From here, the light rays are converted into electrical impulses that travel to the brain, where they are then converted into images. If the light isn’t focused correctly on the back of the eye, then the brain can’t process the images accurately.

There are many types of IOLs that may be used depending on the needs of each person undergoing the Clarivu treatment. The most common type of IOL is called a posterior chamber lens, meaning it is placed behind the iris within the capsule which holds the eye’s crystalline lens. The iris is the membrane in front of the eye’s lens that manipulates the size of the pupil, regulating the amount of light that enters the eye.

Other IOLs include:

• Monofocal IOLs, provide a set focal point, usually for distance vision. This allows patients to see clearly within a range.
• Monovision or blended vision is a technique the surgeon may choose to perform that involves inserting an IOL in one eye for near vision and an IOL in the other eye for distance vision.
• Multifocal IOLs, or advanced technology IOLs, treats multiple focal points and reduces or eliminates the need for eyeglasses or contact lenses.
• Accommodative IOLs are considered monofocal, meaning they have a fixed focal point. This type of lens is designed to move in response to your eye’s own muscle, which translates into the ability to see multiple focal points
• Astigmatism Correcting IOLs or toric IOLs are designed to eliminate the eye’s natural astigmatism reducing the need for gasses after surgery. These lenses may be monofocal or multifocal.

No single lens works best for everyone. Only your Optegra eye doctor can determine the most appropriate option for you and will work with you to help select the right course of treatment.
