The goal of this clinical trial is to observe the role of PRF in treating ophthalmic diseases.The efficacy and safety of PRF were validated for four ophthalmic conditions: macular hole, pterygium, corneal ulcer, and patients undergoing trabeculectomy for glaucoma. The main question aims to answer is PRF's effectiveness in ocular surface and fundus diseases. Participants will be divided into 2 groups, the experimental group will be treated with PRF and the control group will be treated with conventional surgery, with a 12-month postoperative follow-up to determine the role of PRF on wound healing in ophthalmic diseases.
