Perfect
Vision Optical do not perform laser surgery,
however, due to our relationship with the
Medical community we are able to refer the appropriate
candidates seeking laser surgery to an experienced practitioner
without the need to visit a General
Practitioner, please feel free to talk to us
about laser surgery.
The shape of
your eye determines how
good your vision can focus. Light
rays enter the eye through the
cornea, then
through the pupil and the lens.
In a normal eye the light rays are
focused onto the retina, a light-sensitive
tissue lining the back of the eye.
Signals from
the retina are sent through the optic nerve
to the brain, where they are interpreted as
the images we see.
Refractive
errors exist because the curvature of the
cornea doesn't match the length of the eye
so light rays cannot focus properly on the
retina. Refractive surgery procedures
attempt to fix this by changing the shape of
the front surface (the cornea) or adding a
permanent lens to improve the focus.
