This is also called retinal cryotherapy. It is a procedure that uses freezing to seal off a retinal tear or leaking blood vessel.
This is mainly used in the treatment of retinal tear, retinal detachment and most times diabetic retinopathy.
The doctor first numbs the eye using a local anesthesia, then he places a probe that releases cold to the spot where he wants to seal off. Afterwards he releases high intensity cold to the spot for over thirty minutes.
The procedure is very safe and non invasive.
