Cataract Surgery

Cataract surgery is the most common surgery performed in the U.S. today. It is performed on an out-patient basis and can offer significant improvements to vision. In cataract surgery, the clouded lens of your eye is replaced with a plastic lens, an intraocular lens (IOL). Cataract FAQ’s.

What are cataracts?

Cataracts are a slowly-progressing discoloration of the lens of the eye that probably actually starts the day we are born. The lens is crystal clear at birth but slowly turns brown with age, mostly due to UV-induced changes in the proteins of the lens. Everybody’s lens discolors with age but not everybody needs cataract surgery. Eventually, the brown discoloration of the lens may interfere with vision and that’s when you need cataract surgery.

When do you need cataract surgery?

Cataract surgery is elective. You have cataract surgery when your lens has discolored to the point that you are having difficulty seeing to perform your daily activities. Typical cataract-induced vision complaints are glare in bright light or at night from headlights, blurred, dim or distorted vision. The cataract does not physically damage the eye but it sure can blur the vision. When you are having difficulty seeing to do your daily activities, like driving, especially at night, reading, seeing to walk safely, etc., then you need to consider cataract surgery.

Obviously, if you are having difficulty seeing to perform your daily activities, you need to have your eyes examined. Cataracts aren’t the only cause of blurred vision. You may just need your glasses prescription updated, or you may have other problems with your eyes, like glaucoma, macular degeneration, dry eye, etc.

Cataract surgery.

During cataract surgery, a small, self-sealing 1/8 inch incision is made in your eye’s cornea – the clear, outer layer of your eye. The wound is so small it does not even usually require a suture to close. The lens of your eye is removed and an intraocular lens (IOL) is inserted in its place. The IOL is not susceptible to discoloring like your original lens. You may feel pressure during your cataract surgery, but the majority of patients do not describe the procedure as painful. Anesthetic eye drops are administered to numb your eye.

IOL (Intra-Ocular Lens) options.

There are many different IOL options available. Traditionally, monofocal IOLs have been used in cataract surgery. Monofocal IOLs focus the eye at one distance only and do not correct astigmatism. These lenses are usually covered by insurance and, depending on the lens selected, will allow you, without glasses, to see distance and/or near objects. With monofocal IOLs, you may have to use eyeglasses to read, see the computer and/or see clearly in the distance for driving or TV.

However, if you are interested in decreasing your dependence on glasses, we do have an opportunity, with Multifocal intraocular lens implants, to significantly decrease your dependence on glasses after cataract surgery, permitting you to see to read, see the computer and drive without glasses.

Cataract surgery is the most commonly performed surgery in the US. Cataract surgery has an extensive safety record, and serious complications are rare and usually treatable.  In my practice, 97% of cataract surgeries are without complication.
After your surgery, you may experience:

  • Itchy eyes
  • Dry eyes
  • Blurry vision
  • Mild discomfort
  • Discharge from your eyes

Most patients can return to normal daily activities within 24 hours after cataract surgery with only minimal restrictions. Your vision may continue to adjust to the IOL for a month or so, and you may want to use reading glasses during this time. After about a month, your eyes and vision should adapt to the IOLs.  If you need glasses to fine tune your vision, the glasses are typically prescribed 3-4 weeks after surgery.

The blurriness and poor vision caused by a cataract can be devastating and can interfere with your day-to-day activities. If a cataract is affecting your ability to drive, read and enjoy life, cataract surgery may be right for you.
