As we know, glaucoma surgery is to create a channel on the surface of the eye to allow the atrial fluid to flow out, so that the atrial fluid in the eye can drain smoothly to the surface of the scleral wall and change the elevated intraocular pressure caused by the lack of atrial fluid flow. Many people believe that since they have had surgery, they should “supplement” their diet in order to make the wound heal as quickly as possible. Therefore, many glaucoma patients eat a lot of high-protein foods after surgery, such as fish, chicken, eggs, meat, turtle, seafood, etc. The reason for this is that the post-operative diet of glaucoma should not be “supplemented”. The reason is that glaucoma surgery is small and there is no loss of materials in the body; moreover, for other surgeries, we want the wound to heal as fast as possible, but for glaucoma surgery, we do not want to filter the wound to heal too fast, but hope that the wound, especially the inner layer of the wound, heals as slow as possible, preferably for life. This is because once the inner wound heals, the scar in the surgical area is formed and the new atrial aqueous pathway we designed and created is blocked, and the IOP is bound to rise again, signifying that the glaucoma surgery has lost its effect and may require additional IOP-lowering medications or another anti-glaucoma surgery. In particular, patients with scarring should avoid a diet high in protein and fat, because their scarring ability is much stronger than that of ordinary people, and if they are given a diet high in protein or fat, the healing of their surgical incisions will be accelerated, leading to surgical failure. Therefore, after surgery, glaucoma patients should have a light diet with fresh vegetables, soy products, fruits, etc. They can eat meat, eggs, milk, etc., but they should not take “big supplements”, especially for scar patients.
