Vitrectomy is the last ace in the hole for defending vision in patients with glycoplasty. Proper post-surgery care, medication, and review are each step that affects the success of the surgery. Today, we will tell you 3 things you should focus on after vitrectomy surgery. The first thing you should do after biosurgery is to learn to keep your head down Biosurgery If you have pumped gas or oil, you should insist on keeping your head down from the post-op period to let the gas and oil better top the retina. Whether you sit or lie down, eat or sleep, make sure the back of your head is directed to the ceiling and your face is parallel to the floor or bed surface. This is usually done for a month, but the first two weeks after surgery are the most critical. Many patients find it difficult to keep their heads down, but in fact, even in the first two weeks after surgery, you can raise your head appropriately if you are too tired. However, note that you should never tilt your head, and the maximum degree is to ensure that your head is upright, because tilting your head can cause gas or oil to top the lens inside the eye, which can easily get cataracts. After the first two weeks also try to keep your head down for as long as you can, but during that time you can go out and move around and live your normal life without restrictions. After eye surgery, of course, you cannot do without eye drops After biosurgery, in addition to insisting on keeping your head down, you also need to take eye drops. Generally, anti-inflammatory and dilating eye drops should be used after surgery. The anti-inflammatory eye drops are used to avoid infection after surgery; the dilating eye drops are mainly used to prevent the pupil from sticking together, once the pupil sticks together, it will become smaller and difficult to spread out again, which will affect future examination and surgery. Generally, post-operative anti-inflammatory and dilating eye drops should be used for about 2~4 weeks. After the biosurgery, it is more important to review Some patients have biosurgery, the redness and swelling of the eyes is a normal reaction after the surgery, and usually will recover slowly in about a month, so don’t worry too much. However, do not think that you should not go to the hospital for review because everything else is fine except for the redness and swelling of the eyes, but you should follow the doctor’s instructions strictly for review within two to four weeks after biosurgery. Generally, one week after the surgery, you have to review the retina, mainly to observe the bleeding, reset the situation, whether the pupil has recovered, etc. The doctor will tell you the time of the next review according to the current review. It is important to follow the time ordered by the doctor, because each patient’s condition is different and recovery is different. If you do not review on time, the condition may have changed and the patient does not feel anything yet. Of course, in addition to normal medication and review, it is especially important to develop a good habit. After biosurgery, you should control your blood sugar and blood pressure, and pay attention not to catch cold and diarrhea, etc., which can affect the health of your eyes. In addition, it is also important to pay attention to a balanced diet and rest.
