A refractive error is a vision disorder where the shape of the eye does not allow light to focus perfectly on the retina, resulting in blurred or distorted vision. The types of refractive error are short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. Presbyopia is also a type of refractive error, however it is caused by ageing changes in the eye rather than shape irregularities at the front of the eye. For many patients, laser or refractive surgery options can remove their refractive error, eliminating the need for corrective glasses or contact lenses and providing patients with clear and comfortable vision.
