This is a general guide to the various types of laser eye surgery available – the end visual result is the same for all three procedures.

An initial assessment is required to determine which procedure is most appropriate for you.

The initial assessment involves comprehensive testing and measurement of your eyes, as well as an in-depth discussion with a vision correction surgeon about your visual goals and lifestyle considerations, realistic visual outcome, potential risks, recovery period and costs.
