Corneal Refractive Therapy

Wouldn't it be fantastic if your nearsightedness could be corrected while you sleep?  

It might sound too futuristic to some people, but it's a reality. It's called orthokeratology, or ortho-k, and it is available right here at Takahashi Eye Care

By working with Dr. Takahashi, she can prescribe a method of possibly rectifying your nearsightedness while you sleep. By wearing specifically customized contact lenses your eyes surface will be gently reshaped allowing you can see clearly even after you remove the lenses. 

Ortho-k: (CRT)  

Reshaping the cornea with contact lenses to improve vision isn't some new or futuristic concept. Orthokeratology has been practiced for decades. In June of 2002, the FDA granted overnight wear approval to a type of corneal reshaping called Corneal Refractive Therapy (CRT). 

At the same time, new manufacturing methods and lens designs were enabling orthokeratology lenses to achieve a far superior success rate than experienced ever in the past. The performance of "reverse geometry" or "return zone" designs have fueled new excitement about orthokeratology. (Opening the door to new technologies and a variety of medical advancements.)

How it works is a fascinating process. Myopia (nearsightedness) is caused by light coming into your eye in such a way that it doesn't focus properly on the retina. Typically, in the past this problem is corrected by the patient having to wear eyeglasses or regular contact lenses to "re-focus" the light rays. 

Who Is a Candidate?    

Orthokeratology (CRT) is for people of any age who are nearsighted. The FDA has approved CRT for people with up to six diopters of myopia (-6.00 on your prescription). Astigmatism can also be treated: up to -1.75 with CRT.

The procedures can be performed on practically anyone of any age, as long as their eyes are healthy. Ortho-k holds particular appeal for people who participate in sports, or who work in dusty, dirty environments that can cause problems for regular contact lenses. 

Because ortho-k offers similar benefits to LASIK, it's also appealing to adolescents and teens, who are not eligible for LASIK.

What Results Can You Expect from Ortho-k (CRT)?   

In the FDA clinical study for approval of CRT, 93 percent of patients achieved 20/32 vision or better, and 67 percent achieved 20/20 or better. 

How Long Does Ortho-k (CRT) Take?    

That depends on the individual patient. Claiming that a "miracle" will occur over night is unrealistic. It usually takes 2 to 4 weeks of "eye training" to achieve the patients specified goals. Once your eyes reach the desired prescription, you will need to wear lenses when you sleep or during part of the day to maintain your prescription. Discontinuing lens wear altogether will allow your corneas to gradually regress to their original shape or close to it. 

Ask Dr. Takahashi for more detailed information or simply call for an appointment to see if you are a candidate for CRT. (734) 332-8840
