Ophthalmology refers to the branch of medicine that deals with the eye.
Epping Surgery Centre provides ophthalmology corrections for the following eye conditions: Refractive errors, cataracts, glaucoma, retina, eye conditions as a side-effect of diabetes, macular degeneration (AMD), strabismus, oculoplastics, keratonconus and pterygium.
How the eye works
The human eye works similarly to a camera, with a focusing ‘lens system’ at the front of the eye and a light sensitive ‘film’, the retina, at the back of the eye. The crystalline lens acts as an ‘auto-focus’ system, similar to a camera, enabling us to focus on whatever interests us.
The cornea is a curved dome of strong, clear tissue on the surface of the eye and is one of its most critical components. The cornea refracts light rays so that they focus on the retina at the back of the eye. Refractive errors occur when the cornea fails to focus light rays precisely on the retina. LASIK eye surgery is used to improve refractive errors.
The epithelium is a thin protective layer for the cornea which heals very quickly when disturbed.
The iris is the coloured part of the eye. The iris is actually a muscle which controls the size of the pupil.
The pupil is the black circular area in the middle of the eye. It expands and contracts to controls the amount of light reaching the retina.
The retina is a membrane on the inner wall of your eye, which changes light into images which are then transmitted to the brain via the optic nerve.
The sclera is the outer white coat of the eye, which helps to protect the eye.
A natural lens behind the iris changes shape to allow the eye to focus. As you age, the natural lens hardens, resulting in presbyopia – often referred to as loss of reading vision.
In a normal eye, light rays of an image pass through the cornea and lens, focusing directly on the retina to create a clear image. When this focus on the retina isn’t achieved, a refractive error results and the vision is unclear.
