Types of Multifocal Lenses

Multifocal lenses have revolutionized cataract surgery. In the past, patients were not given much of a say when it came to the lenses implanted after cataract surgery. In fact, the decision was left up the physician. Now, advancements in technology have made it so that patients have a large say in which lenses are used.

Which multifocal lens is used depends largely on the patient’s feelings about wearing glasses after surgery. While the lens may not eliminate the need for glasses, the number of situations in which they are needed can be reduced.

There are several different types of multifocal lens implants and ultimately, your surgeon will be able to determine which one will work best to help you achieve your corrective vision goals.

Presbyopic Correcting Lens Implants

These types of multifocal lenses can finally free many patients from reading glasses. With presbyopic IOLs, patients can have clarity of sight at close, intermediate, and far distances. Two types of presbyopic implants are the ReSTOR and Crystalens. ReSTOR is made of a flexible plastic that allows the lens to focus light on the retina and produce clear images both near and far. The Crystalens is an accommodating lens that can move and change its shape based upon the location of the object being viewed, much like the natural eye lens. Crystalens is a great option for patients who wish to have clear vision at intermediate distances.

Lens Implants for Astigmatism

For patients who desire a full range of vision after cataract surgery, multifocal IOLs are an excellent option. It is important to note that since these types of IOLs are considered premium, the patient is responsible for paying the difference between this and the standard monofocal lens. This added expense is worth the additional freedom from corrective eyewear for many patients who opt for multifocal lenses. Your cataract surgeon can advise you on the advantages and disadvantages of both types of lenses during your initial consultation.
