As we age, beginning around the age of 40, the natural lens inside the eye begins to harden and lose its flexibility. This reduces the eye’s ability to change its focus from near to intermediate, to distance, and back again. This is known as “loss of accommodation” or “presbyopia,” and its earliest symptom is difficulty seeing things up close. Bifocal and even trifocal glasses BEHome necessary for some people to see clearly at all distances.As the natural lens of the eye continues to deteriorate, it starts to become cloudy or brown. Vision becomes blurry, and colors lose their brilliance. At first, frequent changes in glasses prescriptions can help, but left untreated, cataracts can lead to blindness. The only way to see clearly after a cataract matures is to have it removed and then replaced with an intraocular lens, or IOL.
50 this would mean that you still need glasses for either reading or for distance vision. Multifocal IOL’s have now been introduced with allow for freedom of glasses while undergoing cataract surgery. Multifocal IOLS accomplish t3his by incorporating several ‘rings’ that focus at different distances and accommodative lenses do so by moving within the eye. The multifocal IOL lens can increase your chances for a life free of dependence on glasses or contacts after cataract surgery for near, far, and intermediate vision. If you have worn glasses for a very long time this might be an opportunity for you to eliminate this hassle from your life.
Multifocal IOL’s may help you in getting rid of glasses Activities like shaving are a lot easier
With Monofocal IOL’s you get good distance vision but need glasses for near vision and reading. With multifocal IOL’s you get “BOTH” good distance and near vision
If you opt to receive a monofocal lens implanted in both eyes for distance vision, you will definitely need reading glasses after surgery. If you receive a multifocal lens there is a good chance you wont need glasses. 80% of patients implanted with the diffractive and refractive lenses in their respective FDA clinical trials did not need glasses after surgery for distance or near vision. Of course, not every patient in the trial was spectacle independent. The odds of BEHoming free of spectacles are better if your corneal astigmatism is low and your eyes are healthy
No. … Patients with a history of corneal refractive surgery (CK, RK, PRK, LASIK, etc.) may require additional refractive surgery following implantation of a multifocal lens to optimize its performance
Multifocal IOLs are effective at improving near vision relative to monofocal IOLs although there is uncertainty as to the size of the effect. … Good unaided distance visual acuity (VA) is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation
While monofocal lenses are still considered standard for cataract surgery, many patients cannot help but consider multifocal lenses. Although these lenses have not been around nearly as long as monofocal lenses have, they still offer some unique advantages that are worth exploring.
In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
