What is a Cataract?

To understand a cataract, it is important to understand how the eye works. The eye functions much like a camera. Light rays enter the eye, passing through the cornea, then the pupil and through the lens. The lens bends the light rays to focus objects onto the retina, lining the back of the eye. From there, the image passes through the retinal cells, into the optic nerve, and finally to the back of the brain which processes the images.

Cataracts occur when there is a buildup of protein in the lens that makes it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. Since new lens cells form on the outside of the lens, all the older cells are compacted into the center of the lens and  a cataract is formed.  When the lens becomes cloudy it is then called a cataract.

Understanding Cataracts

Types of Cataracts Include:

  • Age-Related Cataracts – This type of cataract develops as a result of aging.
  • Congenital Cataracts – Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born.
  • Secondary Cataracts – These types of cataracts develop as a result of other medical conditions, such as diabetes, exposure to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation.
  • Traumatic Cataracts – These form after injury to the eye.

Other factors that have an effect on the eye and that can increase a person’s risk of developing cataracts include cigarette smoke, air pollution, heavy or frequent doses of steroids, and heavy alcohol consumption. The forming of a cataract can significantly reduce vision and ultimately reduce longevity of life, as a recent study has shown.

What are the Symptoms of a Cataract?

Cataracts usually form slowly and cause few symptoms until they noticeably block light. When symptoms are present, they can include:

  • Vision that is cloudy, blurry, or foggy; having difficulty reading street signs, reading a newspaper, seeing TV captions, following a golf ball, etc.
  • Progressive nearsightedness.
  • Changes in perception of color because the discolored lens acts as a filter.
  • Problems driving at night, such as glare from oncoming headlights.
  • Glare problems during the day from sunlight.
  • Double vision (appears as a superimposed image).
  • Frequent changes in glasses prescriptions? Needing more light to read.

How Are They Diagnosed?

An eye exam should be given to test how well you can see wearing your glasses (be sure to bring them to your appointment). The doctor will dilate your pupils in order to examine the condition of the lens and other parts of the eye.

Why Tyson Eye for Your Cataract Surgery?

Founded in 1980 by Dr. Benjamin G. Martin, Tyson Eye is one of the most experienced providers of eye care and surgery services in Southwest Florida. Tyson Eye pioneered ambulatory surgery in Cape Coral in 1988 when the practice opened the first free-standing ambulatory surgery center in that location. The Eye Surgery & Laser Center is fully licensed by the State of Florida as an Ambulatory Surgery Center (ASC) and is approved by Medicare and the Accreditation Association for Ambulatory Health Care. It is the only facility in Cape Coral where eye surgery is performed. Tyson Eye is a second-generation medical practice that is dedicated to bringing its patients quality care and the latest clinical advancements.

Experienced Surgeon

As one of the most notable cataract surgeons in the area, Dr. Tyson’s expertise provides him access to the most cutting-edge advancements and newest technology in ophthalmic care. Dr. Tyson offers the latest in cataract surgery, the “Cold Phaco” cataract removal system.

The Cold Phaco System is the most gentle and efficient method of cataract extraction. The tip of the instrument is introduced into the eye through a small incision. Localized, high frequency waves are generated through this tip to break the cataract into very tiny fragments and pieces, which are then suctioned out through the same tip in a controlled manner. A thin ‘capsule’ or shell is left behind after removal of the entire opaque cataract. A folded intraocular lens is inserted through the micro-incision, then unfolded and set into permanent position. The small incision is “self-sealing” and usually requires no stitches. This type of incision heals fast and provides a much more comfortable recuperation.

Dr. Tyson is one of the first physicians in the world utilizing intraoperative wavefront technology during cataract surgery and is one of few ophthalmologists currently implanting the new FDA-approved Tecnis® Multifocal IOL. Tyson Eye is the only facility in Cape Coral equipped to perform eye surgery, and has the only Cold Phaco System in Southwest Florida. Dr. Tyson performs all eye surgeries personally and works with the patient pre and post operatively. He has been performing these types of surgical procedures for more than a decade as well as lecturing on surgical procedures and practices internationally.

Dr. Tyson was the first surgeon in Florida in a nonacademic setting to use the Tecnis™ Lens, an intraocular lens which offers increased contrast sensitivity. In 2004, he was the first surgeon in Southwest Florida to perform the latest bimanual micro-incisional cataract surgery. Dr. Tyson is a national instructor for other ophthalmologists learning this technique. In 2005, Dr. Tyson was the first surgeon in Southwest Florida to use the ReZoom® multifocal lens.

Dr. Tyson practices among an elite group of eye physicians leading the research and development of new treatments for cataracts and eye diseases. The Tyson Eye is an FDA-certified clinical trial facility, recently testing new interocular lens and treatments for cataracts. A Johns Hopkins graduate with a degree in Biomedical Engineering, Dr. Tyson’s contributions continue to assist ophthalmologists worldwide in their ability to offer patients new advancements in vision technology. This translates to our patients receiving the most up-to-date eye care.
