You don’t have to endure long wait times to receive your regular retinal screening, since screening can be performed at local sites without the need for dilation. These screenings also create a permanent record of your eye health for future comparison, so any changes in your eye can be detected early enough to protect your vision.
Vision & Aging
As we get older, it is very important to make regular eye exam part of Thompson Optics Edmonton for maintaining good eye care. Here is a short list of the most common conditions:
This is very common over the age of 40. It is the loss of ability to change focus from far to near. It is often the first indication that our eyes are not what they use to be. The most common signs include the tendency to hold reading material further away, blurred vision while doing near tasks and eye fatigue when attempting to do close work.
This can result when excessive fluid pressure within the eye damages the optic nerve. Glaucoma often has no pain or visual symptoms in the early stages of the disease. However, it can slowly cause a permanent loss in your peripheral vision. Glaucoma can be effectively treated with prescription eye drops. In some cases, surgery may be required. Early detection is the key to success.
We found another common condition during eye exam in Edmonton. Cataracts occur as the crystalline lens within the eye becomes cloudy, resulting in blurred vision. Cataracts are most often in persons over the age of 55.This condition may cause prescription changes in your Eye Glasses and eventually surgery. Cataract surgery is simple quick and painless.
Age-related Macular Degeneration ARMD
This is one of the most common conditions of the eye to effect seniors. It is also the leading cause of blindness in adults over the age of 55 in North America. Macular degeneration is a disease that blurs/distorts your central vision causing increased difficulties with reading, watching TV and driving. There are two types of macular degeneration.
The most common type is
1. Dry Macular Degeneration
There may be a family history of this condition. Treatment consists of a specific multivitamin which has been shown to slow the process of the disease.
2. Wet Macular Degeneration
is much rarer. It causes sudden vision loss in the effected eye and requires a referral to a retinal specialist. The specialist will often treat this condition with injections and occasionally with laser treatments.
Several common health conditions, such as arthritis, high blood pressure and diabetes may affect your eyes and vision. In their early stages, these conditions may not cause symptoms or create problems, and therefore go undetected.
Regular eye check ups are vital to catching problems early and maintaining healthy eyes.
Keratoconus is a progressive disease that involves the thinning and steepening or "bulging" of some, but not all, of the cornea. The area affected is usually at or near the center of the cornea.
About one in 2,000 people are affected by keratoconus. The disease progresses for four to seven years.
Keratoconus affects both eyes in about 96% of cases, with one eye typically progressing more than the other.
In keratoconus, the cornea becomes very irregular in shape and increases in astigmatism. Because of the cornea's unusual shape, eyeglasses and soft contact lenses can't fully correct vision to an acceptable level.
GP Contacts for Keratoconus
About 15% of keratoconic individuals ultimately require a corneal transplant, but most can benefit from wearing GP contact lenses.
Watch this video about Brian Davis, a keratoconus patient who wears GP lenses over soft lenses (called a "piggyback fit") to correct his vision. The rigidity of a GP lens helps to smooth out the front surface of the eye and improve vision — usually by several lines on the visual acuity chart.
GP contact lenses for keratoconus are custom-fitted to an individual's eyes with assistance from a "color map" that depicts the topography of the cornea. This helps the eye care practitioner to choose the best diagnostic lens to fit.
Newer GP Lens Options for Keratoconus
New GP lens designs have been introduced that allow better alignment of the back surface of the lens to an irregular cornea. One option is large-diameter GP lenses, known as scleral or semi-scleral lenses.
They're so named because the lens is shaped to remain completely above the cornea, without touching it at all; the outer edges of the lens rest on the sclera (the white part of the eye). The space between the lens and the cornea is filled by tears. This provides comfort as well as a smooth optical surface that corrects vision problems.
Hybrid contact lenses are another innovation that benefits people with keratoconus. These lenses use a GP center, which provides the crisp optics for which GPs are known, along with a soft outer ring.
Hybrid contact lenses may be used when a GP lens alone can't provide an optimal fit or causes discomfort. In such cases, an eye care practitioner may also resort to a "piggyback" fit — that is, a GP lens on top of a soft lens. In the video featured on this page, one wearer describes his experience with a piggyback fit for keratoconus.
At Thompson Optics we fit all these types of lens designs for patients with Keratoconus, for a free consultation call us to book an appointment.
