Will I be suitable for laser eye surgery? Whilst the majority of patients who attend a FREE consultation are suitable candidates, not all will be. We treat eye prescriptions of up to four and a half dioptres of long sightedness, up to twelve dioptres of short sightedness or up to six dioptres of astigmatism. For some there may be a health or eye condition which means laser eye surgery is not the best optical solution for them. Other eye surgery procedures are available for those who are either not suitable for laser eye surgery or would benefit from an alternative solution as a result of their clinical evaluation. To be considered you must be over the age of 18.
