Tired of glasses and contacts? Not interested in laser surgery?
​Maybe CRT therapy is right for  you! 

     What is CRT?

This video demonstrates how CRT ( Corneal Refractive Therapy ) aka Orthokeratology (Ortho-K) works.

Myopia treatment with CRT  - also know as Ortho-K
​
Drs.  Hong and Forister, as  mothers of school age children themselves, understand parents’ concerns when it comes to the progression of their children’s nearsightedness (a.k.a. Myopia). Parents often feel helpless when their child’s glasses prescription increases year after year.  According to the most recent studies, the methods of myopia control can be divided into two categories:

1. Delay the onset of myopia
2. Slow the progression of myopia once the child already has myopia.

 

The consensuses among the most recent studies show that an increase in the time spent on outdoor activity is very effective in delaying the onset of myopia but is not as effective in controlling myopia progression once it has occur.  However, the following myopia control treatments have shown clinical statistical significance in slowing down the progression of myopia by approximately 50%.

1. Pharmacological: off-label use of one drop of mid-to-low dose of Atropine therapy every night.
2. Overnight corneal refractive therapy-CRT ( orthokeratology)
3. Myopia treatment day time soft contact lenses

​Myopia treatment is not just to slow down the growth of the patient's prescription, but also slow the progression of the axial length of the eyeball. Increased axial length due to myopic progression may increase risk for retinal detachment, holes, tears, and other complications in the eye. 

What is CRT (Ortho-K)?
CRT is a non-surgical procedure using specially designed contact lenses to gently reshape the curvature of the eye to improve vision while you sleep. 
​
This is a revolutionary non-surgical procedure that eliminates the need for glasses or daytime contact lenses. It improves vision by gently reshaping your eye while you sleep using specially designed therapeutic contact lenses. Place the specially fitted lenses on your eye at bedtime, and when you wake in the morning, you will have clear, sharp, natural vision for your waking hours.   his safe and effective treatment can correct near-nearsightedness and astigmatism up to certain prescription range. It is a great alternative to LASIK for those who don’t want the risk or are not ready for surgery.  ​

作為學齡兒童的母親，我們了解父母對於兒童近視進展的擔憂。當孩子的眼鏡處方年復一年的增長時，父母經常感到無奈。根據最近的研究，近視治療方法可分為兩種類型：
1. 延緩近視的發病。
2. 一旦孩子已經有近視, 如何控制近視的進展。

最近的研究之間的共識是，室外活動時間的增加對於延遲近視發生是非常有效的，但一旦發生，室外活動時間就不能有效地控制近視進展。然而，以下近視治療方式在最近的臨床研究統計顯示減慢近視進展約50％:

1. 藥理學：每天晚上使用一滴中低劑量的阿托品治療。
2. 過夜角膜重塑隱形眼鏡治療CRT（角膜矯正術）
3. 雙焦軟式隱形眼鏡

這些治療方案的確切治療根據仍然是未知的。然而，研究人員在十多年的研究中已經觀察到上述治療方法與眼球長度增長和近視進展減慢相關。
