Corneal Refractive Therapy: Correct Nearsightedness without Surgery

Dr. Steven Chander offers Corneal Refractive Therapy (CRT) as an effective and non-surgical alternative to laser vision correction. With CRT, you will wear a set of custom contact lenses while you sleep. The oxygen-permeable lenses will reshape your cornea to temporarily correct myopia (nearsightedness) and other vision problems.

Also known as orthokeratology, this form of treatment can dramatically improve your vision without the discomfort or recovery associated with surgery. CRT has been used for more than 20 years, and it is safe for a wide range of patients, including children. To discover if CRT is right for you, schedule a consultation with Dr. Chander today.

We have found that children often benefit the most from this treatment because it can help to halt the progression of childhood myopia.

What Is Corneal Refractive Therapy?

Nearsightedness occurs when the cornea does not refract light properly. CRT is an innovative form of vision correct that uses specialized contact lenses to reshape corneas while a patient sleeps. When the patient wakes up, he or she will experience sharper eyesight and may not need to wear corrective lenses during the early hours. If we determine that CRT is right for you, Dr. Chander will provide you with a set of personalized prescription lenses. These innovative lenses are made of a special material that will allow oxygen to pass through them.

Two CRT lenses

When you begin treatment, you may need to wear your lenses for part of the day, as well as throughout the night. After the first week or two, however, you will likely only need to wear them while you sleep. It is important that you maintain your treatment schedule, or your eyes will revert back to their original shape. To help protect the health of your eyes, we recommend having your CRT lenses cleaned and polished biannually. In most cases, patients will need to replace their contacts every other year.

Candidates for Orthokeratology

If you suffer from moderate nearsightedness or slight astigmatism, you may be a good candidate for CRT. Additionally, patients who have been disqualified from undergoing LASIK surgery because of thin corneas, dry eye, or another concern often choose this treatment as an effective alternative. CRT is suitable for adults, older patients, and children as young as seven. In fact, we have found that children often benefit the most from this treatment because it can help to halt the progression of childhood myopia. 

Benefits of Corneal Refractive Therapy

When compared to other forms of vision correction, CRT offers several benefits, including:

  • Safety: This form of treatment has been approved by the Food and Drug Administration (FDA) and used safely for more than 20 years. Similar to wearing traditional contact lenses, CRT involves very minimal risks. 
  • Simplicity and Comfort: Because CRT is non-surgical, you will not have to worry about setting aside time for recovery. Furthermore, most patients experience virtually no discomfort.
  • Convenience: CRT eliminates the hassle and stress of contact lenses. The treatment can be especially beneficial if you play sports, work in a dusty environment, or find it difficult to wear contacts for some other reason.
  • Effectiveness: According to one FDA clinical study, 93 percent of CRT patients enjoyed 20/32 vision or better after treatment, and more than 65 percent achieved 20/20 vision or better. In a separate FDA study, 95 percent achieved at least 20/40 vision (the legal requirement for driving) and 73 percent enjoyed 20/20 vision or better.

We can review the full benefits of this innovative treatment during your initial CRT consultation.
