Correction of Hyperopia
Hyperopia, or farsightedness, is a refractive error that exists when
light rays bend incorrectly into the eye. The condition, which is caused
by an abnormally flat cornea or shortened eye, forces the rays to fall
behind the retina, instead of directly on it, thus making it difficult
to see objects up close.
This common refractive problem affects roughly a quarter of the population,
a rate that increases with age to half of the population over age 65.
Luckily, correction methods for hyperopia continue to be developed.
Currently, hyperopia can be corrected with eyeglasses, contact lenses
and surgery.
During correction for hyperopia, doctors aim to change the way the
light rays enter the eye. Depending on the severity of the condition
and the strength of the prescription (which is always characterized
by a positive number, such as +2.00), it may be necessary to wear glasses
or contacts all the time or simply when reading or performing other
up-close tasks.
The most common surgical options for the correction of hyperopia are
photorefractive keratectomy (PRK) and LASIK. During PRK, a laser is
used to flatten the cornea so the light rays focus closer to or directly
on the cornea. During LASIK, corneal tissue is removed with a laser
to reshape the cornea and correct vision.
