Eye drops after corneal transplantation have become a part of every patient’s life. In the previous article, we talked to you about how to take the correct eye drops, and here we will talk about those misconceptions about eye drops and the extra worries that patients have. In the early postoperative period, especially within a month, it is often necessary to take about 4 types of eye drops, several times a day. The patient’s question then arises: Won’t so many drops go into the eye right after the surgery, and won’t they leak into the wound? The answer is: definitely not! First of all, the wound is like a tunnel, and the outermost layer of the corneal incision – the epithelial layer – heals very quickly, so the wound is very airtight. If the eye drops can get inside the wound, by the same token, the gas inside the eye will come out and bacteria will enter the eye, and the surgery will not be a failure. But since the wound is airtight, why is there a risk of infection? That’s because our eyes are in an open environment, and opening them is in contact with the outside world, so there is a natural risk of infection. So, don’t worry, don’t worry about drops, regular medication to heal faster. In addition to the fear of “leakage”, many patients in the use of eye drops there is a bigger misunderstanding, is a bottle of drops for a long time, so long that it exceeds the use of the deadline. Doctors recommend that general eye drops should not be used after one month of opening; some special drops, such as cyclosporine are formulated, the general use period is within two weeks after opening. Under normal circumstances, within one year after surgery, if the patient drops the medicine regularly, almost used up in about three weeks after opening. Therefore, the saved drops not only cannot be used after the shelf life, but also indicate that there is a problem with the patient’s medication. For some patients who have special financial difficulties, they can use the eye drops from opening until they are used up during the maintenance medication phase one year after the surgery, but they should be observed for any adverse reactions. In addition, some patients do not know much about the preservation method of eye drops. Except for cyclosporine eye drops to be stored at 4°C in the refrigerator, all other eye drops can be stored at room temperature, and it is not necessary to refrigerate all eye drops.
