YAG laser iridotomy is a procedure that creates a tiny opening in the iris to improve fluid flow within the eye. It is mainly used to prevent or treat angle-closure glaucoma in eyes with narrow drainage angles.
How YAG iridotomy works
With the eye numbed by drops, focused laser pulses create a small channel through the peripheral iris. This allows aqueous fluid to move more freely from behind the iris to the front of the eye, helping to equalise pressure and open the drainage angle.
