Contact Lens Policy

Important Information for individuals who wear contact lenses

Contact lenses can "mould" the corneal surface, which changes the corneal curvature and may lead to a change in your refraction (prescription). In order to properly calculate the treatment to correct your refractive error, you will have to stop wearing contact lenses at some stage prior to your appointments. In time, the cornea will return to its natural shape and size. LASIK MD is dedicated to providing you with the most accurate treatment, which can only be achieved if the corneal surface is stable and back to its natural shape.

For the vast majority of patients, the minimum recommended length of time for contact removal should suffice. However, the individual rate of corneal adjusting may vary. If your cornea is still adjusting at the pre-operative appointment, you will be required to reschedule your appointment for a later date. LASIK MD cannot reimburse for time off work, hotel, airline tickets or any other expenses incurred due to rescheduling.

Please note that this is only necessary in the eye(s) that will be undergoing surgery and that patients can wear their contact lenses in the non-operated eye immediately following surgery, if such is the case.

*Do not sleep with contact lenses on for (one) 1 week before the pre-operative evaluation.


The difference in the lengths of time to remove contact lenses listed in the chart ensures that most out-of-town patients are not inconvenienced by rescheduling of appointments if corneal "moulding" is apparent.

Medical evidence suggests that the likelihood of an enhancement is reduced the longer a patient has had their contact lenses out.

1A minimum of 24 hours of soft contact lenses removal is adequate for the majority of patients. On occasion, however, we find that the eyes are red and irritated with some inflammation, during the pre-operative exam. These symptoms are due to wearing contact lenses for long periods of time. The doctor may request to have a second evaluation with contact lenses removed for one week before surgery is booked. The doctor may also prescribe anti-inflammatory drops before surgery can be performed. This occurrence is not common. However, it is important that patients are aware of this possibility prior to surgery.
