Non-Surgical Vision Correction:

Myopia Managment, Corneal Refractive Therapy (CRT), Orthokeratology (Ortho-K)

What exactly is myopia?

Myopia is much more than "just" blurry vision. Nearsightedness is the visual perception that objects at a distance is blurry and clearer up close. Myopia is the condition where the length of the eye is excessively long. Having myopia increases the risk for developming certain eye diseases such as Retinal Detachment, Glaucoma, Maculopathy and early onset of cataracts. In the literature, research has shown a direct relationship between the degree of myopia and risk of these serious eye diseases.

In the technological world, our younger generation is now exposed to technology and screens of all types which can indirectly and directly influence the initial onset and progression of nearsightedness - especially during the rapid growing years. Research has shown that it is a growing epidemic and although there are currently no interventions that stop the progression of nearsightedness, there are alternatives to decrease its progression.

What is Myopia Management/Corneal Refractive Therapy (CRT)/Orthokeratology?

Corneal Molding or Ortho-K
Corneal Refractive Therapy (CRT) involves the use of specially designed rigid gas permeable (RGP) contact lenses to alter the shape of the cornea in order to reduce or correct myopia. It can also be effective with low degrees of certain types of astigmatism.

Light, which gives us vision, is focused largely by the front, clear piece of tissue of the eye called the cornea (the first structure light hits is the tear film)

The CRT lens gently moulds the cornea by applying pressure to the tear film, which in turn is applied to the cornea. This is all done while a person is sleeping. Upon wakening, the goal is to create a sharpened image, eliminating the use of spectacle glasses and/or contact lenses. Because CRT is reversible in nature, when the lens is removed, the cornea begins to return to its orignial shape but so slowly that good vision is maintained all waking hours.

Each night the process is repeated although some find they only need to wear their lenses every other night. The elastic tissue of the eye is not harmed by this process. It is not a permanent alteration of tissue.

 Who is a candidate?

The majority of patients with nearsighted correction with healthy eyes can be potential candidates and benefit from CRT. Patients range from as young as seven years to adults in their 60s.

There are many factors to ultimately determine if you or your child is a candidate. In the context of children with good parameters, we make the decision based on their maturity, hygiene and motivation. These patients enjoy the bonus of being able to play, swim, play sports and other routine daily activities without the need for glasses or daytime contact lens wear. We also take into account their history of their myopia, either there is a strong family history of myopia or the patient who already demonstrated rapid progression of their myopia at each yearly visit.

In the context of patients who are older than ~18 years of age, and adults, the purpose is not for the management of myopia. Rather, the purpose is as an alternative to refractive surgery and other correction. Additionally, patients over forty years old will need to consider that near reading vision may be blurred.
