Cataract Surgery
Cataract Surgery
Cataract surgery involves removing the natural, now cloudy, lens of the eye, and putting a clear artificial lens in its place. The new intraocular lens, or IOL, helps to bend and focus light. IOL’s are generally made out of silicone or acrylic. Learn more about cataracts here.
What is a cataract?
(KA-tuh-RAKT) A condition in which the lens of the eye becomes cloudy. Symptoms include blurred, cloudy, or double vision; sensitivity to light; and difficulty seeing at night. Without treatment, cataracts can cause blindness. There are many different types and causes of cataracts.
What can I expect with cataract surgery?
Before Surgery: Prior to surgery, you will meet with your surgeon in the office for a “pre-operative visit.” At this time, we will take measurements of the eye and help you decide what type of new lens (IOL) would be best for you. You will be prescribed some eye drops to start taking three days before surgery is scheduled. These drops are used to help prevent infection and decrease inflammation after surgery. We can answer any and all questions you have about your upcoming surgery at that visit.
The Day of Surgery: You will be asked not to eat or drink anything after midnight prior to surgery. You will arrive at the surgery center about 1.5-2 hours prior to your scheduled surgery time. The eye will be numbed and dilated with several drops. You will also be given medication through an IV to make you comfortable and relieve any anxiety. You will be awake for surgery but should be comfortable and without pain. The surgery itself generally takes 10-15 minutes, or slightly longer for more complicated cases. Once surgery is complete, you will be taken to a post-operative recovery area for about 30 minutes prior to being discharged to home.
After Surgery: Generally, we place sunglasses over the eyes after surgery to decrease your light sensitivity and protect the eyes. Most patients do not require a patch over the operative eye. You will start your post-operative drop regimen later in the day after getting home. A protective eye shield will be placed over the operative eye at night time. We will then see you the day after surgery to ensure everything is healing appropriately. Most of the healing happens in the first week after surgery but it can take up to a month to completely heal from cataract surgery. We will be monitoring the healing of the eye closely over this time.
If you have cataracts in both eyes, surgery in each eye is typically done 2-6 weeks apart to allow healing of the first eye.

Type of IOL- Lenses
Not every patient is a candidate for any lens. As you plan for your cataract surgery, talk to your physician about your vision needs and expectations. Together you will choose the best lens option for your desired results. Final lens choices will be made together at your pre-operative visit, a few weeks prior to surgery.
Monofocal
The most common type of lens used with cataract surgery is called a monofocal IOL. It has one focusing distance. It is set to focus for up close, medium range or distance vision. Most people have them set for clear distance vision. Then they wear eyeglasses for reading or close work.
Toric
For people with astigmatism, there is an IOL called a toric lens. Astigmatism is a refractive error caused by an uneven curve in your cornea or lens. The toric lens is designed to correct that refractive error.
Multifocal- Multifocal IOLs
These IOLs provide both distance and near focus at the same time. The lens has different zones set at different powers.
