cost and habits decides CRT

Those are my concerns too.  

1) bad effects - CRT is more mature than laser - from technology history to FDA approval.

2) Shall change to soft lens after 16yr old - not necessary.  Soft lens something in eye that prevents sports or swimming.  And you have to wear soft lens every minute during the day.  CRT is 8-hour during the sleep while eye has no movement.

3) Laser - most eye doctors don't recommend laser surgery.  It may go bad after 5yrs.

To be clear, I'm not advertising CRT for anyone.  I'm a mom to share my experience on CRT.  I have the concerns like every mom may have.  I share this to get more advices or comments from other moms or doctors.

CRT能在孩子的成长期控制度数的增长，是不是不会有其他副作用。

比如孩子成年后，视力相对稳定时，

1. 是否可换成隐形眼镜？ 带隐形眼镜比CRT是否更好？

2. 是不是 CRT 后还是可以做 laser, 来完全解决视力问题。
