What Is A Cataract?

Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear, but as we age, normal proteins begin to break down in the lens, gradually developing a cataract and causing blurred and cloudy vision. There are other medical factors that can cause a cataract to develop more rapidly.

Symptoms & Diagnosis

Because cataracts typically develop very slowly, most people don’t realize the lens in the eye is affected until their vision becomes dull or blurry. Common symptoms include:

  • Cloudy or blurry vision
  • Colors seem faded
  • Glare or halos appear around headlights, lamps and in bright sun
  • Double vision
  • Frequent prescription changes

When a cataract begins to affect your ability to perform day-to-day tasks, treatment is required.

Treating Cataracts

Cataracts can be removed only with surgery. If your cataract symptoms are not bothering you very much, you don’t have to remove a cataract. You might just need a new eyeglass prescription to help you see better. You should consider surgery when cataracts keep you from doing things you want or need to do.

During cataract surgery, your eye surgeon will remove your eye’s cloudy natural lens. Then they will replace it with an artificial lens. This new lens is called an intraocular lens (or IOL). When you decide to have cataract surgery, your doctor will talk with you about IOLs and how they work.

People who have had cataract surgery may have their vision become hazy again years later. This is usually because the eye’s capsule has become cloudy. The capsule is the part of your eye that holds the IOL in place. Your ophthalmologist can use a laser to open the cloudy capsule and restore clear vision. This is called a capsulotomy.

Cataracts are very common reason people lose vision, but they can be treated. You and your ophthalmologist should discuss your cataract symptoms. Together you can decide whether you are ready for cataract surgery.

Premium Surgical Options

Modern cataract surgery – which is far less invasive than it used to be – has reached a level of sophistication that allows for better recovery and outcomes. Advances in lens implants (called intraocular lenses, or IOLs) for cataract surgery have enabled surgeons to customize a person’s vision to uniquely match their lifestyle.


Studies have shown the Symfony® Lens is beneficial for distance, intermediate AND extended reading distances, while also able to correct astigmatism. Its major advantage over other Active Life Lenses is its increased depth of focus. FDA studies show that 97% of patients were satisfied with the Symfony® IOL and would have it implanted again, and most patients who had the Symfony® reported being free of their glasses.


TECNIS® IOL can provide patients with youthful, adequate vision using innovative wavefront lens technology. The TECNIS® lens can improve contrast so you can see well, even in low-light situations.


This IOL was created specifically for individuals with astigmatism. This advanced technology is called the AcrySof® Toric Lens, and it has the power to deliver excellent all-around vision, including distance. In recent FDA trials, patients implanted bilaterally with Toric IOLs reported the following: 97% were able to eliminate the need for distance vision glasses 97% achieved vision of 20/25 or better

Having Surgery?

My new implanted lens allows me to see 20/20 for the first time in my life! I had no pain and Dr. Welch and staff are awesome. I would do this again in a New York second!
