When a person is nearsighted, it means the eye is either too long compared to the curvature of the cornea, or the cornea is more curved than normal. This results in light focusing just in front of the retina, instead of directly onto it, causing images at a distance to appear blurry. While myopic patients can often read or perform tasks up close without any corrective eyewear, other activities such as driving will require correction to see clearly.
Glasses and contact lenses can be used to correct myopia by aiding in focusing light precisely onto the retina, however myopic patients are also often ideal candidates for laser vision correction. Laser eye surgery can microscopically sculpt the shape of the cornea so that its focusing power is matched to the length of the eye and light is focused to the correct spot on the retina. By changing the shape of the cornea, the need for glasses or contact lenses is eliminated.
For patients with myopia, both TSA which is “Touchless Surface Ablation” (also known as Transepithelial PRK) and Femto SBK are often viable options. It should be noted, however, that your degree of myopia can be a factor when determining which surgical procedure is appropriate for you.
