What are Cataracts?

A cataract is a painless clouding of the eye’s natural lens. The cloudiness develops as a result of protein buildup in the lens. Cataracts can occur in either one eye or both eyes and affect millions of people each year. Including, more than half of all Americans over the age of 60. If left untreated, cataracts will worsen over time and can lead to permanent vision loss or even blindness.

What Causes Cataracts?

The lens within the eye clouds naturally as we age, causing a gradual reduction of vision. There are numerous other causes of cataracts, including:

  • Alcohol use
  • Diabetes
  • Exposure to radiation
  • Family history of cataracts
  • Illness
  • Injury
  • Medication
  • Prolonged UV light exposure
  • Result of eye surgery
  • Smoking

Cataract Symptoms

Cataracts can be present without patients even knowing. Typically patients do not realize they have cataracts until their vision is affected. Symptoms of cataracts include:

  • Blurry, cloudy, or misty vision
  • Decreased color perception
  • Difficulty reading
  • Double vision
  • Frequent changes in lens prescription
  • Poor night vision
  • Small spots, dots, or halos
  • Vision worsens when lights are dim, very bright, or there is a glare

Dr. Keamy explains the symptoms patients can experience with cataracts.

Diagnosing Cataracts

Whether or not patients are experiencing symptoms, there are a series of tests that Dr. Keamy can perform to diagnose a cataract. The degree of visual impairment determines the treatment method, therefore, early detection can allow patients to avoid surgery. To diagnose cataracts patients can go through a dilated eye exam, visual acuity test, tonometry, or slit-lamp examination. Alone or in combination, these tests can determine if a patient has cataracts or their symptoms are a result of a different condition including glaucoma or macular degeneration.

What is Cataract Surgery?

Cataract surgery is a minimally invasive procedure to remove cataracts. Surgery is typically performed on an outpatient basis using local anesthesia. During cataract surgery, the natural cloudy lens of the eye is replaced with a clear artificial lens. The artificial lens, known as an intraocular lens, improves vision. Cataract surgery is a common procedure that is considered safe and effective.

Traditional Cataract Surgery

At Keamy Eye & Laser Centre we perform a minimally invasive, small-incision, no-stitch cataract surgery called phacoemulsification, also known as phaco surgery. First, Dr. Keamy will dilate the pupil and numb the eye with anesthesia. Then, a tiny incision is made to insert the small ultrasonic probe. The probe breaks up or emulsifies, the cloudy lens into tiny pieces which are then suctioned out. After removing the natural lens, Dr. Keamy will place the intraocular lens or IOL. There are a variety of IOLs and the appropriate type will be determined during your consultation.

Once the IOL is in place surgery is complete. Due to its small size, the incision will be able to heal on its own with only a topical eye drop. Therefore, there are no injections or stitching in the eye at all. The whole procedure takes about 30 minutes and patients can typically leave the facility after their surgery.

While traditional cataract surgery can provide patients with improved vision it does not provide the precision and customization that comes with laser-assisted cataract surgery. At Keamy Eye & Laser Centre, we use the Catalys system from OptiMedica for laser-assisted cataract surgery. The Catalys system is the only laser system created specifically for the surgical treatment of cataracts. Instead of just measuring and mapping the eye, the Catalys offers advanced optical coherence tomography to obtain much more detailed, high-resolution images of the eye.

Prior to surgery, Dr. Keamy will take all of the information provided by these images and design a personalized surgical plan for the patient’s unique eyes. The Catalys system additionally features state-of-the-art image guidance technology that recognizes the various surfaces of the eye and generates safety zones that help Dr. Keamy determine the optimal location for an incision and target the treatment area precisely.

Cataract Surgery Recovery

After surgery, patients are required to wear an eye patch or protective shield for several days. Vision will be blurry at first but improves in the days following surgery. In the case that both eyes have a cataract, which is common, surgery is done on one eye at a time. Surgery for the second eye is typically scheduled a month or two later to ensure the first eye is fully healed.
