How to prevent dry eyes after LASIK?

Just wanted to add in a word of advice about coloured contact lenses. Coloured contact lenses contain extra pigment to give the contact lens its colour. Depending on the manufacturer or brand of these contact lenses, the application process of this pigment on the contact lens might not be done well or properly. This is especially so if the coloured contact lens is not FDA-approved or have not been through any stringent regulations or certification.

When there are symptoms suggestive of any potential eye disease, I would recommend addressing the underlying problems first before embarking on any form of surgery, refractive surgery included. Complaints such those you described are suggestive of dry eye and refractive error instability which would warrant caution prior to making any decision for surgery. Should you have any concerns, it would be perfectly appropriate for you to raise them with your surgeon. Work closely with a trusted surgeon to decide on the best course forward. Otherwise, a second opinion could help allay your worries.
