Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.
Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don't have to stay in the hospital after the surgery. Cataract surgery can be done traditionally using ultrasound energy to remove the cloudy lens or it can be removed with laser-assisted technology. Cataract surgery is very common and is generally a safe procedure.
Complications after cataract surgery are uncommon, and most can be treated successfully.
Cataract surgery risks include:
- Drooping eyelid
- Dislocation of artificial lens
- Retinal detachment
- Secondary cataract
- Loss of vision
Your risk of complications is greater if you have another eye disease or a serious medical condition. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.
How you prepare
To prepare for your cataract surgery, you may be asked to:
- Undergo tests. A week or so before your surgery, your doctor performs a painless ultrasound test to measure the size and shape of your eye. This helps determine the right type of lens implant (intraocular lens, or IOL).
- Stop taking certain medications. Your doctor may advise you to temporarily stop taking any medication that could increase your risk of bleeding during the procedure. Let your doctor know if you take any medications for prostate problems, as some of these drugs can interfere with cataract surgery.
- Use eyedrops to reduce infection risk. Antibiotic eyedrops may be prescribed for use one or two days before the surgery.
- Fast before surgery. You may be instructed not to eat or drink anything 12 hours before the procedure.
- Prepare for your recovery. Normally you can go home on the same day as your surgery, but you won't be able to drive, so arrange for a ride home. Also arrange for help around home, if necessary, because your doctor may limit activities, such as bending and lifting, for about a week after your surgery.
