Eye conditions such as cataracts and presbyopia usually require lens replacement surgery, using artificial intraocular lenses (IOLs). There are several types of IOLs available, but there is an ongoing debate about monofocal vs multifocal lenses, to determine which one is better. However, there are pros and cons related to both types of lenses.
Cataracts and presbyopia
A cataract is a clouding of the lens of the eye, resulting in blurry or double vision, as well as sensitivity to light. Cataracts are generally not harmful, and very often thereare no symptoms in the early stages, but it can cause vision loss if it is not treated.
People with presbyopia are unable to focus on near objects, therefore activities such as reading fine print becomes difficult. Presbyopia has traditionally been treated with reading glassless, but more recently, lens replacement surgery has gained popularity.
Choosing a replacement lens
Prior to the operation, the lens are measured to determine how strong the artificial lens needs to be. The choice of lens will determine the area of your focus after surgery i.e.near or distance focusing.
Monofocalvs Multifocal Lenses
Monofocal lenses provide improved vision at a single distance. That means patients willnotice an improvement in either near or distancevision. Multifocal lenses improve both near and distance vision.
Monofocal IOLs are the standard choice, but multifocal lenses are considered more attractive for people who want to be free of eyeglasses. Multifocal lenses are high performance premium lenses, and this makes them more expensive than monofocal IOLs. While most insurance carriers cover monofocal lenses, multifocal IOLs are not fully covered.
