A type of laser which emits in the ultraviolet range of the spectrum. In ophthalmology, it is used for removing tissue from the cornea, particularly in refractive surgery.

In the human eye the term fovea (or fovea centralis) is the “pit” in the retina that allows for maximum acuity of vision. The human fovea has a diameter of about 1.0 mm with a high concentration of cone photoreceptors. The centre of the retina, the area of greatest visual acuity. Small depression in the central part of the macula located close to the optical axis of the eye. Central area in the macula that produces the sharpest focus. Contains a high concentration of cones which aid in clear central vision.
