眼内手术时,病人和医生均关心伤口的良好愈合。已知手术后第25天,角膜中央伤口的张力强度增至最大,此后趋于稳定。周边角膜伤口愈合速度在手术后第11天时达到最高。局部应用维生素A醇可加速伤口胶原成分的形成和增加皮肤伤口的张力,促进角膜上皮再生。维生素A是以维生素A醇的形式存在于泪液中,本研究系观察维生素A对白内障伤口愈合的影响。
During intraocular surgery both the patient and the doctor care about the good healing of the wound. Known 25 days after surgery, the tension in the central corneal wound increased to a maximum intensity and then stabilized. Peripheral corneal wound healing rate reached the highest on the 11th day after surgery. Topical application of vitamin A alcohol can accelerate the formation of wound collagen components and increase the skin wound tension and promote corneal epithelial regeneration. Vitamin A is in the form of vitamin A alcohol in the tear, this study was to observe the effect of vitamin A on cataract wound healing.
