It is common to experience some level of dryness after laser vision correction (ReLEx SMILE, LASIK, PRK).
Typically, SMILE and PRK have a lower incidence rate of dryness as compared to LASIK. Having said that, as every patient heals differently, there may be some variation in the recovery time for each individual.
Patients may experience dry eye for a few weeks to months after SMILE and will thereafter improve gradually. It usually take about 3 months for the vision to stabilise. Generous use of artificial tears after surgery may help to alleviate the symptoms of dryness.
