Nearsightedness or Myopia
For the nearsighted eye, distant objects are incorrectly focused.
Components of the nearsighted eye are not precisely in tune. The refractive power of the cornea (the outer layer) is too high (or the eye is too long) causing light rays to focus in front of rather than directly on the retina. This results in unfocused and blurry vision.

However, a nearsighted person is able to see close images very sharply because the light rays from these near objects are bundled on the retina.
Today, there are several surgical procedures available to correct nearsightedness:
| Eye laser procedures | Nearsightedness | |
| iLASIK, Femto-LASIK | up to -8 (-10) dpt. | |
| Epi-LASIK | up to -6 dpt. | |
| Monovision LASIK | up to -8 (-10) dpt. (in combination with presbyopia) | |
| Lens procedures | ||
| Acrysof Cachet phakic lens |
-6 to -16 dpt. | |
| Phakic lens implant | -1 to -23,5 dpt. | |
| Refractive lens exchange |
from -8 dpt. | |
| Multifocal lenses | yes (in combination with presbyopia) | |
| Combination procedures | ||
| Bioptics | yes |
