目前,后房型人工晶体植入虽常用于矫正无晶体眼的视力,但仍有不少眼科医生继续使用前房型人工晶体。术后由于角膜内皮细胞的丧失,可引起角膜水肿。这种角膜内皮的远期改变,引起了医生们的极大关注。以前曾有报告,在单纯的白内障囊内或囊外摘出术后3个月内,角膜中央部内皮细胞的密度趋于稳定。然而,对植入前房型或后房型人工晶体后,内皮细胞密度的变化,仍有争论。最近的研究表

At present, although posterior chamber intraocular lens implantation is often used to correct the vision of aphakia, there are still many ophthalmologists who continue to use anterior chamber intraocular lenses. Corneal edema can be caused by loss of corneal endothelial cells after surgery. This long-term changes in the corneal endothelium, aroused great concern of doctors. It has previously been reported that the density of endothelial cells in the central cornea tends to be stable within 3 months of simple cataract or extracapsular extraction. However, changes in endothelial cell density are still debated after implantation of anterior chamber or posterior chamber intraocular lens. Recent study table
