Before the procedure, the eye is cleaned with an antiseptic solution and small amount of fluid is removed from the eye. A gas bubble is then injected directly into the eye and will remain for 3-8 weeks depending on the gas that is used. The gas slowly dissipate on its own. During this time, the patient will be instructed on specific head positioning. During the next couple of days, the patient will then return for either laser photocoagulation or cryotherapy to treat the retinal tear. With the gas bubble in the eye, the patient will be restricted from flying in an airplane and should notify the anesthesiologist if any anesthesia will be needed for procedures.
