As explained above, the procedure removes the vitreous gel from the eye. The first step is to prepare the area for the intervention. The medical staff will use anaesthesia to numb the eye treatment site. They will clean the eye using an antiseptic solution and cover it with a sterile material. A speculum will keep it open throughout the manipulation. The eye that is not going to be operated on will be put a protective dressing. The surgeon will make a cut of about 0.5 millimetres, approximately the width of an eyelash, in the eye membrane. They will work through the pars plana which is located in the white of the eye. Using forceps, the specialist can open the incision and then insert a small microscope that will enable them to see the troubled area. With the help of a vitrectomy probe, they cut the gel that is causing the problem and suck the fluid up with a special tool. At this point, there are different methods that the eye surgeon can go by. They may treat clots and abnormal blood vessels, if such exists, and fix any retinal injuries. If there is bloody, cloudy or infected fluid, they will drain it using a silicone-tipped needle. A laser can be used to burn the affected site and cause scarring. It is precisely the scar tissue that will serve to keep the retina attached to the eye later on. When this part of the surgery is over, the vitreous gel will be replaced with something similar to silicon oil, air bubble, gas, or saline solution. The last step is to apply an antibiotic solution to the treated area to prevent infection. A protective bandage is put onto the eye. There are other methods that can be used to seal the retina to the eye such as cryopexy (a freezing treatment), however, they are not the subject of discussion here.
