Well, of course no. you are not supposed to wear contact lenses after the vitrectomy surgery. As we know that after the surgery, your eyes can be sensitive, and even they are very fragile. If you wear contact lenses, it can be irritants for your eyes, and then lead to some eye infection. In some cases, it can also lead to pink eyes, influencing the recovery of the surgery. So just do not wear contact lenses. Also, do not overuse your eyes, or it will cause eye strain too. And generally speaking, after the first week of the vitrectomy, you can wear the contact lenses, by dropping some eye drops to avoid eye infection and inflammation.
