Coma - A higher order aberration which makes points of light look like comets with blurry tail-like smudges. It can be diagnosed and treated with wavefront-guided LASIK procedures.

Complex Wavefront Retreatment - An off-label use of the excimer laser to do corrective secondary surgery after the original wavefront-guided surgery has left the patient with higher-order aberrations.

Lacrimal gland - The small structure in each eye which produces tears. It’s above the outer corner of the eye, and lacrimal ducts run from the inner corner to the nose. See also punctum and nasolacrimal duct obstruction.

Laser - Although this is used as a word now, it was originally the acronym for Light Amplification by the Stimulated Emission of Radiation. There are many lasers, all man-made for specific purposes. Laser light has a single wavelength (i.e., color), rather than all colors like everyday white lights. Its waves are directional rather than scattered, and each wave is in step with the next one, which vastly increases the power of a laser light.

: Macular Edema - Pooling of fluid in and around the macular area of the retina, which causes swelling and impairs vision. It causes blurriness, waviness of straight lines, light sensitivity, and a pink tint to the vision. It usually happens as a result of disease or injury and sometimes after eye surgery. Most people recover from it in a matter of months.
