Out of the multiple criteria that a patient has to fulfill to be deemed suitable for laser vision correction would be a stable refractive error for the past 12 months before surgery is performed. It is important to note how much your myopia has worsened and over what course of time. It would be best to determine these values by going through a comprehensive pre-laser evaluation which can give your surgeon accurate information of your eyes before recommending any form of laser vision correction. Also, other aspects of the eye must also be considered including corneal shape and thickness, past medical history, current medication, etc.
