Laser Eye Surgery Assessment

Vision can be categorised according to the ability to see at three different key distances:

  1. Near vision: ability to read a book/newspaper or thread a needle.
  2. Intermediate-range vision: ability to read a computer monitor or price on a supermarket shelf.
  3. Distance vision: ability to drive confidently and see street signs, watch a movie in a theatre or watch live sport.

The focus of the lens of the eyes is controlled by a muscle, which contracts to bring objects held close into focus. At the clinic, vision is assessed in two scenarios:

  1. With the eye muscle relaxed, distance vision is assessed.
  2. With the eye muscle contracted, the ability of the eye to focus close-up is assessed.
