Retina is reattached to the wall and breaks or tears are sealed by a welding procedure
called laser or ice treatment called cryopexy to make sure that it remains attached.
Ensuring to hold the retina back to the wall until effects of laser and cryo treatment take
place the back of the eye is filled with a gas or an oil.
