Almost all eyes will have some refractive error. If they are of the ' higher order' variety the brain will ignore these most of the time. Indeed they may not be evident until later in life when they are combined with other disorders such as cataract or presbyopia.
For ' lower order' variations however correction is often needed.
These include, myopia or short sightedness, hyperopia or long sightedness, astigmatism and presbyopia.
Lower order refractive error can be detected at a routine eye examination.
Mr Aggarwal uses wavefront analysis to detect and treat higher order abberations during the treatment of lower order variations, to provide the very best possible outcome.
