Corneal Refractive Therapy (CRT) is a non-surgical vision correction method designed to temporarily reshape the cornea while you sleep. Using specially designed gas-permeable contact lenses, CRT gently changes the curvature of your cornea to improve how light focuses on your retina, allowing you to see clearly throughout the day - without the need for glasses or daytime contact lenses.
When you wear CRT lenses overnight, they apply gentle, controlled pressure to the corneal surface. While you sleep, the lenses reshape the outer layer of your cornea - the clear, dome-shaped part of your eye responsible for bending light. By the time you wake up and remove the lenses, your cornea retains the new shape temporarily, resulting in clearer vision throughout the day. The change is reversible, meaning your eyes return to their original shape if you stop wearing the lenses consistently.
Corneal Refractive Therapy is ideal for:
Nearsighted individuals (myopia): CRT is most effective for mild to moderate myopia.
Children and teens: It’s an excellent option for slowing the progression of myopia in younger patients.
Active adults: Perfect for people who prefer not to wear glasses or contacts during sports or outdoor activities.
Those not eligible for LASIK: Patients seeking a non-surgical vision correction alternative.
Your eye doctor will begin with a comprehensive eye exam to determine if CRT is right for you. Advanced corneal mapping technology is used to design custom-fit lenses tailored to your unique eye shape.
Night 1-2: You’ll wear the CRT lenses overnight and may begin noticing clearer vision after the first few uses.
First Week: Vision typically stabilizes within a few days to a week of consistent use.
Ongoing Care: Regular follow-ups ensure the lenses fit properly and your corneal health remains optimal.
To maintain clear vision, CRT lenses must be worn every night or as directed by your optometrist.
