WHAT IS A CATARACT? The leading cause of reversible blindness in the world. A partial or complete loss of transparency of the crystalline lens substance and its capsule. When a cataract develops, the lens becomes opaque and prevents the light rays focusing on the retina. The image that the retina receives becomes dull and fuzzy. [/vc_column_text][vc_column_text]View Video[/vc_column_text][vc_separator][vc_column_text css_animation="fadeInDown"] Sight and the normal eye Sight is possible with the combination of a healthy eye and brain. Inside the eye, behind the cornea is the coloured part of the eye (iris) with the black hole in the centre (pupil). Behind this is a lens. Light rays pass through the transparent cornea through the pupil and are then focused through the lens onto the retina. In a normal eye, the lens is made of a clear, flexible gel surrounded by the transparent lens capsule. The lens adjusts its curvature to fine focus light rays onto the back of the eye (retina).

The normal process of aging causes the lens to harden and become cloudy. This is called age-related cataract and it is the most common type of cataract. Other major causes of cataract include the following: Diabetes and injury to the eye (blunt or perforating). Long-term use of systemic steroids can also induce a cataract. High exposure to ultraviolet light and environment degradation speeds up the process of cataract development. Some babies are born with congenital cataracts, which are hereditary. [/vc_column_text][vc_row_inner equal_height="yes"][vc_column_inner width="1/2"][vc_column_text]Some of the symptoms of cataracts include: Dull and fuzzy vision and sometimes double vision Glare from bright sunlight or poor vision when viewing oncoming automobile headlights at night Photophobia Difficulty in performing routine tasks such as reading the newspaper Change in colour perception Night driving [/vc_column_text][/vc_column_inner][vc_column_inner width="1/2"][vc_gallery interval="3" images="3089,3090,3091,3092" img_size="full" css_animation="left-to-right"][/vc_column_inner][/vc_row_inner][vc_separator][vc_row_inner][vc_column_inner width="2/3"][vc_column_text css_animation="fadeInDown"] WHEN SHOULD A CATARACT BE TREATED? Among so many patients and ophthalmic workers, there is a misconception that a cataract has to be fully matured and the patient has to be blind before the cataract can be operated on.These days, thanks to advantages and results of Phacoemulsification (see below), a cataract can be done at any time when the reduction in vision interferes with the normal activities of patients, like driving, reading, playing sports, etc. For a cataract patient, the usual eye test charts of opticians, which are known as Snellen charts, are inadequate. There are special charts known as contrast sensitivity charts, which will fabricate the vision of cataract patients in their working environment like driving at night or in bright sunlight. Sitting in the doctor’s or optician’s office with a normal Snellen chart, the patient’s sight could be as good as 80%- 90% while the same patient’s vision drops to 10% whilst driving.

Keratoconus is the leading cause of blindness especially among the youth in East Africa. A normal cornea (see definition of cornea below) is shaped like a watch glass, but sometimes it starts thinning and bulging; this is known as Keratoconus (Kerato meaning Cornea and Conus like a cone). In such cases, the cornea cannot perform its main function of focusing light rays entering the eye on to the retina due to its distorted shape. [/vc_column_text][/vc_column_inner][vc_column_inner width="1/2"][vc_single_image image="3915" img_size="full"][vc_column_text]Normal Eye[/vc_column_text][vc_single_image image="3914" img_size="full"][vc_column_text]Eye with Keratoconus[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text]View Video[/vc_column_text][vc_column_text] Here the middle part of the cornea becomes weak and thin. As a result, it cannot withstand the pressure of the eye causing the cornea to bulge. The exact cause of Keratoconus is not known, but it is believed that it could be due to a malfunction in the enzymes, which make the stroma (please see cross-section of the cornea) weak. It could also be associated with allergy and there is some evidence that it may be hereditary. Keratoconus is also linked with over exposure to sunlight, improper contact lens fitting and constant eye rubbing. If there is progressive stretching in the Descemet’s membrane, it leads to rupturing of the membrane and can cause hydrops, where the cornea becomes completely cloudy as shown in the picture below.
