What is a multifocal intraocular lens, and who are they for?
Multifocal intraocular lenses are intraocular lenses designed to enable patients to see both near and far without using glasses.
When a standard monofocal intraocular lens is inserted during cataract surgery the patient sees far ahead, but needs glasses to read close-up. But if the patient receives a multifocal intraocular lens then after surgery they will no longer need glasses, they will be able to see distance and close-up without glasses.
Improvement in the patients far and near vision, being able to see both distance and close-up without glasses, will not deteriorate over time, it lasts a lifetime.
Multifocal lenses are not only for cataract patients. They can also be used for people who want to be able to see both near and far without glasses, however, the structure of their cornea is not suitable for laser treatment such as PresbyMax which is applied to the corneal tissue.
With this method, people who cannot undergo laser treatment due to high myopia, hyperopia, astigmatism or thin corneas, can become free of the need to wear glasses.
This type of eye surgery may not be appropriate for every patient, a thorough eye examination and some tests are needed before the operation.
