Cataract Awareness and Prevention

It's National Cataract Awareness Month

According to the World Health Organization, cataracts are responsible for 51% of cases of blindness worldwide - although this blindness is preventable with treatment. In fact, research shows that in industrialized countries about 50% of individuals over the age of 70 have had a cataract in at least one eye. This is partially because cataracts are a natural part of the aging process of the eye, so as people in general live longer, the incidence of cataracts continue to increase.

What are Cataracts?

Cataracts occur when the natural lens in the eye begins to cloud, causing blurred vision that progressively gets worse. In addition to age, cataracts can be caused or accelerated by a number of factors including physical trauma or injury to the eye, poor nutrition, smoking, diabetes, certain medications (such as corticosteroids), long-term exposure to radiation and certain eye conditions such as uveitis. Cataracts can also be congenital (present at birth).

The eye’s lens is responsible for the passage of light into the eye and focusing that light onto the retina. It is responsible for the eye’s ability to focus and see clearly. That’s why when the lens is not working effectively, the eye loses it’s clear focus and objects appear blurred. In addition to increasingly blurred vision, symptoms of cataracts include:

“Washed Out” Vision or Double Vision:

People and objects appear hazy, blurred or “washed out” with less definition, depth and color. Many describe this as being similar to looking out of a dirty window. This makes many activities of daily living a challenge including reading, watching television, driving or doing basic chores.

Increased Glare Sensitivity:

This can happen both from outdoor sunlight or light reflected off of shiny objects indoors. Glare sensitivity causes problems with driving, particularly at night and generally seeing our surroundings clearly and comfortably.

Dulled Colors:

Often colors won’t appear as vibrant as they once did, often having a brown undertone. Color distinction may become difficult as well.

Compromised Contrast and Depth Perception:

These eye skills are greatly affected by the damage to the lens.

Darkened Vision:

Often individuals with cataracts find that they require more light than they used to, to be able to see clearly and perform basic activities.

Cataract Treatment

Early stage cataracts may be able to be treated with glasses or lifestyle changes, such as using brighter lights, but if they are hindering the ability to function in daily life, it might mean it is time for cataract surgery.

Cataract surgery is one of the most common surgeries performed today and it involves removing the natural lens and replacing it with an artificial lens, called an implant or an intraocular lens. Typically the standard implants correct the patient’s distance vision but reading glasses are still needed. However as technology has gotten more sophisticated you can now get multifocal implants that can reduce or eliminate the need for glasses altogether. Usually the procedure is an outpatient procedure (you will go home the same day) and 95% of patients experience improved vision almost immediately.

Cataract Prevention

While doctors still don’t know exactly how much each risk factor leads to cataracts there are a few ways you can keep your eyes healthy and reduce your risks:

  • Refrain from smoking and high alcohol consumption
  • Exercise and eat well, including lots of fruits and vegetables that contain antioxidants
  • Protect your eyes from UV radiation like from sunlight
  • Control diabetes and hypertension

Most importantly, see your eye doctor regularly for a comprehensive eye exam. If you are over 40 or at risk, make sure to schedule a yearly eye exam.

Dear Patients,

Dr. Lewis Eye Care has made the difficult choice to temporarily close due to the COVID-19 virus pandemic based on the recommendation of the CDC. We cannot perform eye exams while maintaining social distancing, so continuing to see patients at this time could contribute to the spread of the virus.

Our initial plan had been to reopen Monday April 6th. However, as we get closer to that date it is becoming apparent that we may have to be closed for a longer, indefinite period of time.

If you are having an urgent eye health issue, there are some clinics in our area that are seeing patients for emergencies during shorter business hours. You should call ahead to those offices before going to their clinic, as their availability might change day by day. Those clinics could include Vancouver Eye Care at 360-823-2020, Peace Health Medical Group Eye Care at 360-514-7210, and Vancouver Clinic in Salmon Creek at 360-882-2778.

If you need a glasses or contact lens prescription emailed to you from our office, click on the Contact Form link, type in your name, email, and what you are requesting, and we will email you the information you need as soon as we can.

Thank you for your understanding, and please stay healthy during this difficult time.

Sincerely,

Dr. Scott Lewis, OD
