Why Cataracts Need to Be Treated with Intraocular Lens Replacement | HighlandCataracts are the thickening and clouding of the lens of the eye that causes decreased vision. Before the development of intraocular lenses (IOLs), the only option for Highland cataract patients was to wear very thick eyeglasses or special contact lenses in order to see following cataract removal surgery. Today, there are many kinds of IOLs available to address each person’s individual needs.

How IOLs Work

Intraocular lenses were first developed in the 1940s in Britain to replace the damaged lens of the eye. Just like your eye's natural lens before cataract development, an IOL focuses the light that comes into your eye through the cornea and pupil onto the retina where it is relayed to the optic nerve and the brain. IOLs have a prescription to provide the best possible vision for each patient. The following types are available:

  • Monofocal Lenses: This type of IOL has been used for several decades and is set to a particular focal length. Most people choose monofocal IOLs set for distance vision and use reading glasses for near activities. In some cases people choose  a monofocoal IOL that is set for good near vision and use glasses for distance activites like driving or watching television.  Some people opt for “monovision” where one eye is set for distance and the other is set for near vision. The brain adapts and synthesizes the information from both eyes to provide vision at intermediate distances.
  • Toric Lenses:  This is a monofocal IOL with astigmatism correction built into the lens. This IOL can also be set for good distance, near or monovision.
  • Multifocal Lenses: This type of IOL utilizes a series of focal zones or rings to help the patient see both near and far without dependency on glasses.

Our experienced eye doctors can help you determine which IOL is right for you during your personal examination. If you live
