What is Corneal Reshaping Therapy?


CRT is an advanced form of orthokeratology designed to temporarily reshape the cornea and reduce reliance on glasses or contact lenses. This groundbreaking treatment is ideal for patients with myopia (nearsightedness), hyperopia (farsightedness), and astigmatism who want an alternative to traditional corrective methods.

It involves wearing specially designed gas-permeable contact lenses overnight. While you sleep, these lenses gently reshape the surface of your cornea, correcting refractive errors. The result is clear vision during the day without needing glasses or contact lenses.

Is CRT Right for You?


CRT is particularly beneficial for individuals with active lifestyles, athletes, or those who find glasses and contact lenses inconvenient. It’s also an excellent option for children and teenagers whose eyes are still developing, as it can slow the progression of myopia.

Our experienced optometrists at Carmel Mountain Vision Care will thoroughly examine whether CRT is the best option for you, considering factors like prescription strength, corneal thickness, and overall eye health.

What Steps Are Involved in Starting CRT Treatment?


The journey to improved vision with CRT begins with a comprehensive eye exam. Once you are deemed a suitable candidate, we'll take detailed measurements of your corneas using advanced corneal topography. This ensures your custom CRT lenses are perfectly fitted to your eyes. After you receive your lenses, our team will provide comprehensive instructions on how to use and care for them, ensuring a successful treatment experience.

The Benefits of CRT


  • Freedom from Daytime Eyewear: Enjoy clear vision throughout the day without needing glasses or contact lenses.
  • Non-Surgical Alternative: A great option for those hesitant about LASIK or other surgical procedures.
  • Reversible and Adjustable: If your prescription changes or you decide to discontinue use, the cornea will not be permanently changed.
  • Ideal for Active Lifestyles: Particularly beneficial for athletes and those with an active lifestyle where glasses and contact lenses can be bothersome.
  • May Slow Progression of Myopia in Children: Studies suggest that CRT can help slow down the progression of nearsightedness in children.

The Importance of Follow-Up Appointments in CRT Treatment


Continued care plays a pivotal role in the enduring success of CRT. Regular follow-up appointments are necessary to ensure the treatment's effectiveness. These sessions allow us to closely monitor the condition of your eyes and the precise fit of your lenses, adjusting as necessary for optimal comfort and vision correction. Our dedicated team will guide and support your progress at each step of your journey. We provide personalized advice, answer questions, and address concerns, ensuring you feel confident and informed about your treatment.
