Ortho-K/Corneal Refractive Therapy (CRT)

Ortho-K (orthokeratology) is a nonsurgical eye treatment using specially designed contact lenses to gently reshape the curvature of the eye while you sleep to improve vision.   Ortho-k retainer contact lenses are made of highly oxygen permeable material allowing for safe wear while you sleep.

Ortho-K corneal refractive therapy lenses only affect the cornea of the eye. The cornea shape is critical in maintaining a sharp optical focus on objects by bending the light that enters the eye.  The cornea is the clear part of the eye that covers the iris and the pupil.   The corneal tissue is soft and can be subtly molded.  The ortho-k lenses float on your eye tear film, yet provide enough pressure reshape the cornea.

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 need of daytime contact lenses or glasses.  With Ortho-K corneal refractive therapy contact lenses, 20/20 vision can be restored in as little as one day to a few weeks.  The best part is that cornea refractive therapy is safe, non-surgical, non-invasive and reversible.  Results may vary so ask your eye doctor if iSee lenses are right for you or your child.

Ideal Ortho-k (Orthokeratology) candidates are patients who:

• do not want to wear contact lenses during the day

• are children that are beginning to be nearsighted

• are too young for Lasik

• are active in sports and water activities

• want a less expensive alternative to Lasik

• want a non-surgical and non-invasive alternative to surgery
