Ortho-K Therapy Options

Is your child nearsighted? Now there's an alternative to glasses and daytime contact lenses

iSee Ortho-K Therapy Options

Introducing the therapeutic iSee Ortho-K contact lens, an advanced corneal refractive therapy contact lens that corrects nearsightedness and is worn at night.

The purpose of this website is to educate potential patients about how corneal refractive therapy may help them achieve better vision through a treatment process called orthokeratology which is an effective, predictable and reproducible method to correct nearsighted vision. There are several names by which orthokeratology treatment goes by such as corneal refractive therapy (CRT® ), corneal refractive treatment, vision shaping treatment® (VST), and overnight vision correction (OVC).

Ideal Orthokeratology Candidates

  • A desire to be free of glasses or contact lenses during the day.
  • Motivated to wear contact lenses consistently every night.
  • Active in sports and other activities.
  • Children whose parents want to correct and manage their child's nearsightedness.
  • Patients who have difficulties wearing traditional contact lenses because of dry eyes or allergies.

It is important to keep in mind that only a qualified licensed eye care practitioner is able to diagnose and determine the best treatment option that is right for you.

How iSee Corneal Refractive Therapy Works

iSee Ortho-K overnight lenses are designed to gently reshape the cornea while you sleep. Once the lenses are removed in the morning, the slight change in the curvature of the corneal surface results in clear vision during waking hours thus reducing the dependence on daytime contact lenses or glasses.

Ortho-k lenses like iSee lenses have successfully corrected myopia for over 20 years.  The advanced technology and materials utilized in iSee lenses are safe and effective.

iSee Orthokeratology lenses for Athletes and Active lifestyles

No matter what level of sports or activities your child or teenager is involved in, you want them to have the best vision possible. Glasses are a hindrance for any sports enthusiast, whether professional or recreational, and traditional daytime contact lenses can be irritating and inconvenient.

Ortho-K is safe, non-surgical, non-evasive, and reversible. In fact, Ortho-K is so safe that many eye care doctors are comfortable performing corneal refractive therapy for children as young as 7 or 8 years old.

Correcting Myopia (nearsightedness)

Otherwise known as nearsightedness or shortsightedness, myopia is a condition in which your near vision is clear but distant objects appear blurred to an uncorrected eye. This is due to the eyeball getting longer as a child grows during early adolescence. The result is a mismatch between the length of the eye and its optical power causes light entering the eye to focus in front of the retina rather than directly on it.

Using iSee Ortho-K corneal refractive therapy lenses to gently reshape the cornea re-aligns the optical focal point onto the retina allowing patients with nearsighted prescriptions to see clearly all day.

Orthokeratology Solution for Dry Eyes and Allergies

Dry eye syndrome has become increasingly prevalent over the past ten years as people spend more time indoors where air-conditioning systems that remove moisture from the air. Additionally, the substantially greater time spent using digital devices, smartphones and gaming devices reduces blink rates by up to 80% thus dramatically reducing tear flow to the surface of the eyes.

Other common causes of dry eye include the aging process, wearing contact lenses, hormone levels, menopause, birth control, diabetes, environmental factors like allergies, wind, and dry climate, medications, and heavy computer usage.  Thus dry eye syndrome has become one of the most common eye health issues and led to the development of a major market for proposed remedies yet it is unclear that any one product offers the best solution.

Additionally, increasing numbers of people are affected by allergies including the seasonal effects of hay fever which can make it very difficult to wear daytime contact lenses. This is where Ortho-K contact lenses for dry eyes may offer a solution since corneal refractive therapy lenses are only worn overnight when sleeping then removed the next morning to give clear natural vision all day long.

Since Ortho-K lenses are only worn at night while you sleep, dry eye and allergy sufferers may experience relief due to unrestricted tear flow during waking hours.


Orthokeratology Precautions

There is a small risk involved when any contact lens is worn.  It is not expected that iSee lenses for corneal refractive therapy will provide a risk that is greater than other contact lenses.  There were no serious adverse events reported to the FDA in clinical studies.

Only after a thorough eye exam by a licensed physician can it be determined if corneal refractive therapy may benefit you.  There are no guarantees that any specific treatment will work for all patients. Reduction for any individual patient’s myopia may vary depending on that patient’s corneal variables and overall results may vary so ask your doctor if iSee corneal refractive therapy is right for you or your child.
