单靠手术仍不能恢复视力无论是意外失明,还是因白内障引起的水晶体混浊,或者是角膜混浊,只要视网膜、视神经、视觉中枢机能正常,存在光觉(即在暗室中能够分辨光的忽明忽暗),现在可以进行一种把混浊的水晶体摘除,用透明角膜来替代混浊角膜的角膜移植手术。 Surgical alone still can not restore vision Whether it is accidental blindness, or due to cataract caused by crystal opacity, or corneal opacity, as long as the retina, optic nerve, central visual function, there is light (that is, in the dark room to distinguish light flickering Dark), it is now possible to perform a corneal transplanta- tion that removes the turbid crystal and replaces the cloudy cornea with a clear cornea.
