I have defective vision, particularly shortsightedness. Obviously, it is quite widespread phenomenon. I tried several times to get accustomed to contact lenses, but without success. It irritates my eyes. It is required to maintain cleanness of lens in order to prevent conjunctivitis or some other infectious eye disease. It is quite troublesome. I'm also not comfortable with wearing eyeglasses.
If one considers the laser surgery/correction to recover sight, someone probably might be interested in the following questions:
- Is that true that laser correction/surgery for sight recovery can be performed only once in a lifetime. And if after surgery your vision has deteriorated back to poor condition then you won't be able to recover it again using laser correction procedures/technologies.
- What is the state-of-the-art and safest method of laser vision correction. I heard of such methods as LASEK, LASIK, RLE, LRI, PRELEX, etc. Which method is minimally invasive and can be considered state-of-the-art for the moment?
Can you help to clarify these two matters?
