Intraocular Lens: Purposes and Benefits

The Hargrave Eye Center’s latest post:

Your vision is one of the most important things you have. As people get older, vision begins to decline and glasses tend to become thicker. Cataracts are one of the leading causes of impaired vision among individuals. A common procedure that is performed to counteract cataracts is an intraocular lens implant. This article will talk about what kind of intraocular lens implants there are and which ones are the best solutions to certain situations.


Cataracts are one of the most common causes of blindness in the world. Cataracts usually develop over time causing people to have increasingly blurry vision. There are a few different types of cataracts that people can suffer from.


Subcapsular Cataract


Subcapsular cataracts forms beneath the lens capsule. Subcapsular cataracts interfere with reading and can form halo glares around objects. People with diabetes or who take steroids often are more likely to develop subcapsular cataracts.


Cortical Cataract


A cortical cataract begins its formation in the periphery of the eye lens and starts to make its way to the center. The lens cortex is the first area affected by a cortical cataract.


Intraocular Lens or IOLs are used to replace the natural lens on an eye when it is removed during cataracts surgery. The lens is made out of plastic and can be made to significantly improve or stabilize a person’s vision after surgery. There are different types of IOLs that are used for different purposes. Make sure you discuss your best option with your doctor before the surgery.


Monofocal IOL


A monofocal IOL is an IOL that only helps focus on a certain distance. Monofocal IOLs are the most common form of IOLs because they are the most affordable and accessible. A monofocal IOL will require you to continue wearing glasses to help seeing other distances that the monofocal IOL does not cover. Monofocal IOLs can fix either farsightedness or nearsightedness separately. There are other types of IOLs that can help with both near and farsightedness.


Accommodating IOLs


Accommodating IOLs are referred to as premium intraocular lenses. When receiving accommodating IOLs, patients can utilize the IOL for both near and farsightedness. Unlike monofocal IOLs, accommodating IOLs reduce the need to supplement glasses post-surgery because of their ability to help patients see multiple distances.


There are other types of IOLs that are the best fit for each patient. Doctors can determine the severity of cataracts and suggest appropriate IOLs post-surgery for their patients. Certain situations may ask for two different types of IOLs in each eye to ensure maximum benefit after cataracts surgery.
