| Just behind the
pupil of your eye is the lens. This focuses
the light entering the pupil to make a clear
image in the retina. The retina changes the
image into a nerve impulse so that the brain
can “see” it. Usually the lens
of the eye is crystal clear so that it the
light passes through it easily. |
 |
If any cloudiness
develops in the lens then it starts to block
the light passing through and the patient
begins to get blurred vision. This clouding
of the lens is called CATARACT. When the blurring
gets worse it is better to have the cloudy
lens removed by an operation and replaced
by a clear man-made lens. This lens is called
an implant. |
| If you have diabetes
or glaucoma you
can still have cataract surgery in complete
safety. |
