What is a cataract?

A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world.

Today, cataracts affect more than 22 million Americans age 40 and older.
Types of cataracts:

  • A subcapsular cataract occurs at the back of the lens. People with diabetes or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract.
  • A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
  • A cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortex, which is the part of the lens that surrounds the central nucleus.

What Causes Cataracts?

The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. It also adjusts the eye's focus, letting us see things clearly both up close and far away.
The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it.
But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.

Some Cataract risk factors:
  • Family History
  • Diabetes
  • UV radiation
  • Hypertension
  • Obesity
  • Smoking

Cataract Advanced Technology Lens Options

If you require cataract surgery, choosing the right lens implant is a very important decision for you and your doctor. The lens implant selection is the basis for optimum visual enhancement and lifestyle improvement. All current options offer improved vision, while some options also offer much decreased dependence on glasses.

The clinical team and Dr. Collins will determine if you qualify for an advanced technology lens option at your pre-op appointment. These advance technology options offer much improved uncorrected vision, however insurance does not pay for these options. Should you qualify for these advanced technology lenses, there will be additional out of pocket costs.

The three advanced technology lens options are accommodative, multifocal and toric.
Traditional monofocal lenses focus light to only one point in space. This lens implant moves inside as the eye’s focusing muscle contracts, mimicking the eye’s natural ability to focus. An accommodative lens is able to provide vision at multiple distances: near, intermediate and distance vision. This is an option for patients who have both cataracts and presbyopia. This lens option reduces the dependency on glasses.
Traditional monofocal lenses focus light to only one point in space. A multifocal lens implant focuses light from distance and near simultaneously. This feature addresses both distant and near vision and reduces the dependency on glasses.
Toric advanced technology lenses corrects astigmatism (blurred vision due to the inability of the eye to focus a point object into a sharp image), as well as myopia (nearsightedness) and hyperopia (farsightedness).
