An IOL (intraocular lens) is designed to mimic the natural lens of the eye. The IOL focuses the light that comes into the eye through the cornea onto the retina. Most IOL's are made of a flexible, foldable material. Similar to an eyeglass or a contact lens prescription, the IOL will contain the appropriate prescription to give you the best vision possible.
Our doctors here at Fogg, Maxwell, Lanier & Remington EyeCare in Fresno, California are here to help you choose the IOL that is best for you and your lifestyle. Before your surgery, you and your doctor will discuss what you would like from an IOL and which IOL will suit you. The type of IOL implanted will affect how you see when not wearing eyeglasses and, for some people, even get rid of the need for eyeglasses entirely.
This is a very common type of IOL that has been used for several decades. Most people who choose monofocal lenses have their IOLs set for distance vision and keep their reading glasses for up close activities. Some patients choose to have their monofocal lenses set for close-up vision, in which case they would need glasses to see far away. Another strategy, called "monovision", is often used. Monovision means that one monofocal lens is set for near vision while the other monofocal lens is set for distance vision. The brain adapts and uses information from both eyes in order to see at both distances.
These are newer IOL types often used to reduce or eliminate the need for eyeglasses or contact lenses. These IOL types allow patients to see both near and distant objects clearly. It usually takes around 6 to 12 weeks for the eyes to fully adapt to these IOL types following surgery.
For some people, these IOL types may not reduce or eliminate their need for glasses. The success of the IOL depends on each person and their refractive error. Side effects such as glare and halos around light may occur with this lens type.
The toric lens is a monofocal lens with astigmatism correction built in. Astigmatism is a refractive error that causes distortion and blurriness in vision. This IOL is best for those with a significant degree of astigmatism.
