1. Is excimer laser treatment for myopia safe? Yes, it is safe! Excimer laser is an ultraviolet cold laser with a wavelength of 193 nanometers, which will not burn the cornea, and the surgery does not involve any other tissues in the eye except the cornea. 2. What is the post-operative effect of excimer laser? Will it rebound? More than 20 years of practice have proved that the eye is fully developed after the age of 18, and the surgical site is the corneal stroma which cannot be regenerated, so the shape of the front surface of the eye will not change after surgery, so the treatment effect is permanent and will not rebound. More than 95% of the patients can achieve more than 1.0 vision after the surgery and get rid of the heavy glasses once and for all. 3.How long does it take to recover from excimer laser surgery treatment? The surgery takes only about half a minute. It is an outpatient surgery and you can go home the same day after surgery, no hospitalization is needed. Usually you can use your eyes normally the day after surgery, which does not affect your work and study. 4.What is the best result of myopia surgery? 300-1000 degrees has the best post-operative effect.
