A cataract is a clouding of the normally clear lens of your eye. Reduced vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or do many other daily activities. Most cataracts develop slowly and don’t disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision. At first, stronger lighting and eyeglasses can continue to help you see well despite the cataracts. If cataracts start to interfere with your usual activities, you might need cataract surgery. With current technology and surgical techniques, cataract surgery is generally a safe and very effective procedure.
Cataract surgery is an outpatient procedure in which your physician removes the natural lens from your eye and replaces it with an implanted lens. There are various types of intraocular lenses that can be implanted at the time of surgery depending on your visual needs.
A standard IOL is the traditional lens used in cataract surgery. In most cases, it will provide excellent distance or near vision (but not both) in the operated eye. Many people having this type of lens implanted will not require glasses for driving, watching TV and other distance vision activities. However, glasses will usually be required for reading. Patients with significant degrees of Astigmatism will need glasses for all activities.
Toric IOLs are used to correct Astigmatism. Astigmatism is an irregular shape to the cornea (surface) of the eye which causes blurred vision. By placing a Toric IOL, Dr. Rothbaum is able to provide crisper distance or near vision (but not both) than a Standard IOL would offer.
Multifocal IOLs are used to correct Presbyopia (decreased reading/near vision). Presbyopia is an inability of the natural or implanted lens to change shape. This inability makes it difficult to see letters and objects close to our eyes. By placing a Multifocal IOL, Dr. Rothbaum is able to provide significantly crisper near vision than a Standard IOL would offer, along with similar improvements in distance vision.
