白内障术后有多种机制可发生暂时性或永久性眼压升高,人工晶体可能参与其发病机理。重要的诊断线索包括前房深度,有无虹膜切除,房角镜所见及视乳头形态。终身的药物治疗常作为激光或手术治疗失败的补充。无晶体眼滤过性手术失败率高的确切机制尚不明了,与结膜瘢痕、玻璃体和房水性质的改变有关。目前进行提高手术成功率的研究包括发展有效的人工引流植入物,或应用伤口愈合药物调节剂,防止瘢痕形成以改善滤过作用。
A variety of mechanisms after cataract surgery can occur temporary or permanent elevated intraocular pressure, intraocular lens may participate in the pathogenesis. Important diagnostic clues include depth of anterior chamber, iris resection, gonioscopy and papilla. Lifelong medical treatment is often used as a supplement to laser or surgical failure. The exact mechanism of aphakia-free filtration failure is not known, and is associated with alterations in the properties of conjunctival scar, vitreous, and aqueous humor. Current studies to improve the success rate of surgery include the development of effective artificial drainage implants, or the use of wound healing drug regulators to prevent scar formation to improve filtration.
