Refractive surgery is characterized by being performed under local anesthesia and requires verbal communication between the patient and the doctor. If the patient is excessively anxious (which is common for any surgery), it can lead to improper execution of instructions given by the doctor, potentially resulting in complications during the course of the surgery. Similar complications during LASIK surgery can lead to long-term refractive errors, while during SMILE surgery, they can usually be resolved within 1-2 days of post-operative recovery. The advantage of SMILE lies in the fact that the effects of the femtosecond laser used during the procedure are minimally invasive and relatively quick, and the most advanced equipment used helps to minimize negative consequences.
