The correct definition of myopia (shortsightedness) is that it is a refractive condition of the eye in which
parallel rays of light entering the eye come to a focus in front of the retina when the accommodative system (focusing mechanism of the eye)
is relaxed. The amount of myopia a person has is defined by the power of the lens that will correct this refractive error and cause
the parallel rays of light to come to focus on the retina.
Sometimes, eye surgeons will speak of myopic patients having minus power
refraction and the minus power is expressed in terms of 'dioptres'. The eyeball of the child continues to grow till the child is about 8-12 years
of age (when it reaches adult dimensions).
Researchers have found that in highly myopic eyes, the scleral coat of the eye (the tough white outer layer of the eye is thinned and weak.
Using microscopic analysis of abnormal highly myopic eyes, they found a reduction of elastic fiber content in the scleral coat and the individual scleral fibers
were narrowed and more widely separated from one another.
Researchers have found that the cornea and the fluid in the anterior chamber (called acqueous humor) form the main refractive
element of the eye. By changing the curvature of the cornea through refractive surgery, it is possible to alter the refractive status of the eye to the desired power.
