Laser treatment for myopia is currently widely used and well-established in clinical practice. This treatment primarily employs excimer lasers or femtosecond lasers to precisely reshape the corneal stroma—altering both the corneal radius of curvature and corneal thickness—to improve the eye’s refractive status and thereby correct refractive errors.
