Presbyopia is a condition that most people over the age of 40 experience that results in difficulty seeing up close without the aid of bifocals, trifocals, or reading glasses. This age related condition is believed to be caused by the hardening of the lens inside the eye, making it difficult for the eye’s muscles to change its focus.
Until recently, the primary Intraocular Lens (IOL) option for cataract surgery was to receive a “fixed focus” IOL. Patients who received this type of IOL typically had both eyes corrected for distance vision, but usually still required glasses for intermediate and near vision.
Many cataract surgery patients now have the option of the new technologically advanced IOLs that can provide a full range of vision. This means that you can read and see clearly in the distance and everything in between, with little or no dependence on glasses or contacts.
There are several “multi-focal” or “accommodating” IOL options available today. Each lens type has some advantages and disadvantages. Which one is best for you depends on the unique characteristics of your eye, as well as, your lifestyle needs. You and your doctor will decide together which lens is more advantageous for you. Multifocal and accommodating IOLs are considered “premium” IOLs which means there will be additional costs associated with these lenses.
