An optical defect in which vision is blurred. It is generally caused by irregularities in the shape of the cornea or the lens which mean that eye does not focus images sharply on the retina

The clouding of the natural lens in the eye

The transparent front part of the eye that covers and protects the iris and the pupil. Together with the lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power

Excimer laser
The type of ultraviolet laser that is used to reshape cornea in laser refractive eye surgery

Femtosecond laser
A type of laser that can be used instead of a microkeratome blade to form the LASIK flap

Long-sightedness. The eyeball is either too short, or the lens cannot accommodate enough to focus near objects on the retina, resulting in a blurred image. In extreme cases a longsighted person may be unable to focus on objects at any distance.

The thin structure in the eye that gives us eye colour. It controls the size of the pupil and the amount of light reaching the pupil.

Laser-Assisted Sub-Epithelial Keratectomy – a type of laser refractive eye surgery that is similar to PRK

Laser-Assisted in SItu Keratomileusis - a type of laser refractive surgery for correcting myopia, hyperopia, and astigmatism

A precise surgical instrument with an oscillating blade that is used to create the corneal flap in LASIK surgery

Short-sightedness. The eyeball is either too long, or the curve of the cornea is too steep, so images focused at a point in front of the retina, rather than on the retina. Short-sighted people see close objects clearly but things that are further away appear blurred

The gradual, age-related loss of the eyes’ ability to focus on near objects. The precise reason for this is not certain, but research suggests it is most likely associated with a loss of elasticity of the natural crystalline lens in the eye

PhotoRefractive Keratectomy – a type of laser refractive eye surgery that is generally recommended for people whose corneas are too thin to undergo LASIK

The circular opening in the centre of the iris that allows light to enter the eye. It appears black because most of the light entering the pupil is absorbed by the tissues inside the eye

The very back of the eye that consists of millions of cells that are sensitive to light. These convert the images that eye receives into nerve impulses that are sent to the visual centres of the brain
