Cataract

Cataract Surgery

Over half of people over the age of 60 (and many younger than that) suffer from cataracts. Almost everyone develops cataracts as they grow older. Cataract formations occur at different rates and can affect one or both eyes.

A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil.It infers with light passing through the eye to the retina. Aging and other factors cause proteins in the eye's lens to clump together forming these cloudy areas. Early changes may not disturb vision, but over time cataracts typically result in blurred or fuzzy vision and sensitivity to light. People with progressed cataracts often say they feel as if they're looking through a foggy windshield or a piece of wax paper. Surgery needs to be performed when the cataracts have progressed enough to seriously impair the vision and affect the daily life..

Surgery is usually performed on an outpatient basis. A local anesthetic will make the operation painless. Next, under a microscope, a small incision is made into the eye. Microsurgical instruments are used to fragment and suction the cloudy lens from the eye. An acrylic intraocular lens implant is then inserted into the eye to replace the natural lens that was removed. The incision is then closed. When stitches are used, they rarely require removal. Over 95% of cataract surgeries improve vision..

  • Symptoms of cataracts:
  • Decreasing vision with age
  • Blurred or double vision
  • Seeing halos around bright lights
  • Difficulty seeing at night
  • Vision that worsens in sunlight
  • Difficulty distinguishing colors
  • Poor depth perception
  • Frequent prescription changes for glasses
  • Difficulty reading

Advances In Lens Replacement Eye Surgery

During the initial cataract surgery procedures the natural lens that had been removed wasn't replaced with an artificial one, so after the surgery it was necessary to wear very thick eyeglasses or special contact lenses in order to see. Since the mid-1960s the lens has been replaced with an Intraocular Lens (IOL) that is surgically implanted in the eye. The lens used for these replacements has been for years a monofocallens meaning they offer vision at one distance only (far, intermediate or near). But with the use of traditional or standard IOLs you must wear eyeglasses or contact lenses in order to read, use a computer or view objects in the middle distance. There are new "bifocal" implants, that allow each eye to see well at near, far, and everything in between so most people will never need glasses again.

One of the options available is theAcrysoft® ReStor multifocal lens, which can improve vision in a full range of distances from far to near.

The AcrysoftReStor lens is a breakthrough lens that lets patients see from far too near usually without glasses. An innovative optical technology called "apodization" makes the AcrysofRestor lens uniquely effective, especially when placed in both eyes. A similar technology has been used for years in microscopes and telescopes to improve image quality and has now been patented for use in intraocular lenses by Alcon®. Ninety four percent of patients that have these lenses said they would have the lenses implanted again and four out of five recipients reported never wearing glasses after having the lens placed in both eyes.

Most people wanting to get rid of bifocals (with or without cataract) is a candidate for this multifocal IOL's or any patient with an otherwise normal eye exam who needs cataract surgery and wants less dependence on glasses.

Another one of the IOL lenses available is called the Acrysoft® Toric. This lens is used for the treatment of astigmatism. Corneal astigmatism is a common irregularity in which the surface of the cornea is curved more like a football, with both flatter and steeper curves. When the surface of the cornea has an uneven curvature, vision becomes distorted because the light rays are not focused at one spot to provide clear vision. If freedom from eyeglasses for distance vision is important to a patient this would be an option to consider. The lens is made of a biocompatible lens material already implanted in more than 25 million eyes since 1991. A person who has both a cataract and a corneal astigmatism will not regain high-quality distance vision after cataract surgery unless the astigmatism is also corrected.

For those patients who have early stages of cataracts that have not reached the “mature level: can opt to have a replacement lens exchange (RLE). Your eye's natural lens is replaced with an IOL (intraocular lens) to achieve sharper focus. This procedure is done mainly on people who are middle-aged or older that may or may not have the beginnings of cataracts.. Artificial (intraocular) lenses likely can provide significantly better uncorrected vision at that point, especially if you now require vision correction with glasses or contact lenses for near.
