Cataracts are conditions which affect the lenses of the eyes, inhibiting the patient’s ability to perceive light visually. There are numerous known causes, including increased exposure to ultraviolet light, advanced age, a history of vision problems, high blood pressure, eye injuries and diabetes. Cataracts are classified in a number of ways, depending on whether they are progressive or stagnant and whether they cover all or just part of the lens. Conservative management includes the use of special eye drops which break up the cloudy deposits obscuring the lenses of the eyes, but in extreme cases, surgical interventions may be required to restore normal vision.
