With every cataract surgery, after the cloudy cataract is removed, a new clear artificial lens implant is placed in the eye. There are many types of IOLs (intraocular lens implants). Before cataract surgery, your doctor will measure your eye with specialized instruments to determine the best type of lens implant for your eye. There is no perfect lens implant and every type of lens has advantages and disadvantages. Basic lens implants will require the use of glasses after cataract surgery. Upgraded distance, astigmatism correcting, and range of vision lenses are commonly used to reduce the need for glasses after cataract surgery.
Basic monofocal lenses provide clear vision with the use of eyeglasses. Basic intraocular lenses do not correct for the unique shape of your eye and are not designed to correct astigmatism or presbyopia. Most individuals with basic lens implants will need bifocals and/or reading glasses to see optimally far and near.
