Ortho-k in Calgary, AB

Superior Skill and Experience in Ortho-k Vision Correction

Ortho-k, officially termed orthokeratology, refers to a method of vision correction in which you wear rigid gas permeable lenses while sleeping. These specialized lenses are inserted at bedtime and removed when you awaken. Through the night, they gently mold your cornea – thereby correcting refractive error. The next day, you’ll be able to see clearly without any eyewear. The effects are temporary though, and you must wear these revolutionary ortho-k lenses nightly in order to maintain sharp vision during the daytime.

At present, ortho-k specialists work with two brands of lenses that are FDA-approved: Vision Shaping Treatment (VST), from Bausch & Lomb, and Corneal Refractive Therapy (CRT), from Paragon Vision Sciences. For more information about these types of ortho-k lenses, please schedule a consultation in our Calgary eye care center. Our eye doctors are highly qualified and experienced in vision correction with ortho-k.

Who are the best candidates for ortho-k in Calgary, AB?

Ortho-k is typically a good method of vision correction for people between the ages of 10 and 30, with healthy eyes and mild to moderate nearsightedness. In particular, our patients who do not qualify for LASIK procedures are often great candidates for ortho-k. This includes children who are too young for laser surgery, or people with certain eye conditions.

Many people who spend extensive time in dirty and dry environments or participate in active sports find ortho-k to be ideal! It eliminates the need for cumbersome eyeglasses and wearing contact lenses that often become uncomfortable under these conditions. If you engage regularly in water or land athletics, or you are simply tired of glasses and contact lenses interfering with daily tasks, we invite you to our Calgary practice for a meeting with our ortho-k specialists. In particular, sports-minded teenagers who have myopia love the convenience of ortho-k.

Ortho-k is also beneficial for people who suffer irritation from dry eye or eye allergies. These lenses can help you avoid the discomfort that may be experienced when wearing contact lenses.

How successful are the results of ortho-k?

Orthokeratology aims to correct your eyesight to 20/20 without any daytime eyeglasses or contacts. FDA trials demonstrated that over 65% of ortho-k patients were able to see with 20/20 visual acuity after wearing these reshaping lenses overnight. In addition, an incredible 90% of ortho-k wearers achieved 20/40 visual acuity (the legal requirement for driving without vision correction in most states)!

Typically, the milder your prescription, the better your results. If you already have a current vision prescription, call our Calgary, AB, optometrist to inquire if your prescription is within the parameters that can be treated well with ortho-k lenses.

Are the results of ortho-k immediate?

Officially, ortho-k lenses can take up to a few weeks until they reach their full effect. However, many of our patients report that they notice significant improvement after only one night.

During the first few weeks after you begin wearing these vision shaping lenses, your vision may not be as clear you are used to with glasses or contacts. In addition, you may see halos or glare around lights at night. However, these side effects dissipate rapidly.

Who fits ortho-k lenses in Calgary, AB?

We do! Our eye doctors are ortho-k specialists, and we have fit and treated many patients successfully. Generally, an ortho-k fitting takes longer than with standard contacts, because it necessitates a series of office visits. That’s why we use advanced technology and digital optics to evaluate the shape of your cornea, and we won’t compromise on your comfort or vision clarity. We will work with you patiently to ensure a precise fit for your ortho-k lenses. This is the only way to correct your refractive error with optimal accuracy and wearing comfort.

6 Causes of Dry Eyes

Banner for Dry Eye Specialists in Calgary

Our Dry Eye Specialists Explain Causes of Dry Eyes

Are you always rubbing your eyes or blinking constantly to spread more moisture across the surface? Dry eyes can be extremely irritating, even painful for some people. Inadequate lubrication may cause sore eyes, redness, an inability to wear contact lenses and overall uncomfortable vision. At our eye care clinic, our experienced, expert eye doctors will perform a thorough eye exam to diagnose Dry Eye Syndrome.

As every patient is unique, our eye exam will include questions about your personal lifestyle in order to identify what’s causing your dry eyes. Finding the cause is the best way to find an effective solution!

Depending upon the results of your eye exam, we’ll recommend a number of lifestyle changes to help alleviate the annoying symptoms caused by your dry eyes. We asked our Calgary Dry Eye Specialists and they’ve offered 6 possible culprits for Dry Eye Syndrome:

1. Extreme Weather Conditions

Whether it’s summer or winter, extreme weather can stress your eyes so that they can’t produce enough tears to keep your eyes lubricated well. In the winter, it’s helpful to wear goggles or glasses to protect your eyes from frigid temperatures and wind. This is particularly beneficial when you hit the ski slopes or lace up your ice skates. In the summer, heat can lead to dehydration, which saps the moisture from your eyes too. The best way to avoid this problem and stay comfortable is simply to drink enough!

2. A/C or Indoor Heating

Air-conditioning, fans and indoor heating are directly linked with drying out your eyes. Blowing air evaporates moisture from your eyes more quickly, and it also dries out the atmosphere inside your home or office. A humidifier is a worthwhile investment to solve this problem. In the winter, a humidifier will give you an extra bonus of keeping your sinuses moist too, which helps to relieve the symptoms of your winter cold.

3. Seasonal Allergies

Recent studies have shown a strong link between spring allergens and dry eyes. When pollen counts are highest. an increased number of patients visit our eye doctors with complaints of dry eye symptoms. During allergy season, using an air filter indoors may be the most efficient way to avoid the effects of pollen on your eyes.

4. Skin Conditions

Specific skin conditions and disorders are associated with dry eyes. Blepharitis, which refers to an inflammation of the skin along the edge of your eyelids, often leads to Dry Eye Syndrome, because the oil-producing glands are often clogged. This ruins your eyes’ ability to produce tears with a healthy composition of oil. Rosacea, an inflammatory skin condition that generally appears on the face, may also block the oil-producing glands of your eyes.

5. Environmental Effects of the Great Outdoors

While fresh, outdoor air is generally healthy for your eyes, skin and lungs, too much exposure to smoke, wind, dust, and extreme temperatures can certainly lead to eye dehydration. Global climate change has been blamed for many of these ill effects, as your tear film depends upon natural humidity to stay moist. Yet as our environments have changed (and continue to change), the amount of hydration that your eyes can obtain from the outdoor environment has been reduced. Air pollution is also detrimental to healthy eyes, damaging and drying out your tear film.

6. Low-Tear Production

Our eye doctors diagnose many cases of dry eyes that are due to a reduced tear production. Officially termed keratoconjunctivitis sicca, a decreased manufacture of tears can result from a variety of causes. To stimulate tear production, it may be helpful to up your intake of omega-3 fish oil.

Aging is a common reason for inadequate tear production, as well as certain medical disorders, including rheumatoid arthritis, lupus, diabetes, thyroid conditions, scleroderma, vitamin A deficiency and Sjorgen’s syndrome. If you’ve undergone radiation treatments, your tear glands may have suffered damage. Laser eye surgery is another potential culprit, however symptoms of dry eyes due to these procedures are generally short-lived.

When your eyes are unable to keep up with healthy tear production, it’s a good idea to take a look at any medications you’re taking. Common household drugs, such as decongestants and antihistamines are known to affect the moisture level of your eyes. Other medications that could cause dry eyes include: antidepressants, hormone replacement therapy, acne drugs, medication for Parkinson’s disease, hypertension treatment and birth control.
