What is the tiny hole in the middle of your eye?

The tiny hole in the middle of your eye is called the pupil. It is the opening that allows light to enter the eye and reach the retina, which then sends signals to the brain to create visual images. The size of the pupil can change in response to different lighting conditions to regulate the amount of light that enters the eye.


How is a YAG capsulotomy conducted?

A YAG capsulotomy is typically performed as an outpatient procedure. After administering eye drops to dilate the pupil and numb the eye, a laser is used to make an opening in the cloudy capsule behind the intraocular lens. The procedure is quick, painless, and helps improve vision by restoring clarity.

Can the pupil be black in colour?

No, the pupil itself does not have color; it appears black because it is an opening that allows light to enter the eye. The black appearance is due to the absence of light reflecting off the inner structures of the eye, specifically the retina. The surrounding iris can be various colors, such as blue, green, brown, or hazel, but the pupil remains consistently black.
