LASIK (Laser-Assisted In Situ Keratomileusis) is a surgical procedure that uses an excimer laser to reshape the cornea and improve vision by correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. As a popular and effective alternative to glasses and contact lenses, LASIK has become a significant topic in the tech community, driving advancements in ophthalmic technology and influencing the development of new eye care innovations.
