During cataract surgery, the eye's natural lens is removed and replaced with an Intraocular lens, or IOL. Since being approved by the FDA in 1981, IOLs have offered an effective alternative for cataract patients. Prior to the use of IOLs, cataract patients had to wear very thick eyeglasses or special contact lenses in order to see after the natural lenses were removed during surgery.
Types of Intraocular Lenses (IOLs)
Conventional IOLs correct only for near & far sighted vision. While this works well for many patients, those who also have astigmatism may benefit from Toric lenses.
Other IOLs available are Blue Light-Filtering IOLs, which help to filter UV light rays.
How much do IOLs cost?
While cataract surgery and conventional IOLs are covered by insurance because it is considered medically necessary, Toric lenses are more because of their special features. You should discuss the portion of the procedure you will be responsible for with your Ophthalmologist prior to the procedure.
