Dry eye after LASIK is primarily caused by severing of the corneal nerves that stimulate tear production — a consequence of creating the 20mm flap. SMILE’s 2–4mm incision disrupts far fewer of these nerves. Clinical studies consistently show that SMILE patients experience significantly lower rates and severity of post-operative dry eye compared to LASIK patients. For patients who already have borderline dry eye, heavy screen use, or work in air-conditioned environments — all common in Jacksonville — this difference can be clinically meaningful. During your evaluation, our team assesses your tear film and corneal nerve health to help determine whether SMILE or LASIK is the better fit for your eyes specifically.
