Problems and Solutions: Cataracts
Bundaberg and Hervey Bay, Queensland
Cataracts develop very slowly and if you have early cataracts, you are probably not aware of it. However, Dr. Thomas Eshun-Wilson can detect them early and would prefer to detect them early rather than late. Anything that interferes with transparency in the eye’s structures will impair your vision and cataracts are one of the world’s leading causes of blindness.
The Cataract Problem
Briefly, cataracts are a clouding-up of the eye’s lens. Please see How the Eyes Work for more details on the lens and its role in vision. In a healthy eye, the lens is 100 percent transparent so as to let light through to the retina. That full complement of light brings in all the image detail, the color, and the shading of light and dark, that is in the scene you are looking at.
When any piece of that full load of data is missing, your vision is missing some corresponding detail. Cataracts are small opacities that block a little of the incoming light and deprive the retina of a little bit of information. They scatter the light, preventing it from focusing on the retina. Over a few years, cataracts expand and become more numerous, blocking more light.
With moderate to severe cataracts, you will notice a loss of color perception, of sharp focus, and of light and dark differentiation.
The Cataract Solution
To restore your vision, the lens itself must be removed and replaced with an artificial lens, called an intraocular lens (IOL).
