Corneal astigmatism after trabeculectomy and nonpenetrating trabeculectomy

We evaluated the corneal topography and corneal astigmatism before and after glaucoma surgery on 74 eyes. Trabeculectomy was performed on 33 eyes. Nonpenetrating trabeculectomy was performed on 41 eyes. Trabeculectomy was performed as single procedure on 13 eyes. It was performed as triple procedure including cataract surgery and intraocular lens implantation on 20 eyes. Nonpenetrating trabeculectomy was performed as single procedure on 12 eyes. It was performed as triple procedure on 29 eyes. When evaluated by Cravy's method, corneal astigmatism turned into vertical astigmatism 3 months after surgery in each of 4 groups. When evaluated by Jaffe's method, induced astigmatism 3 months after surgery was the greatest in triple surgery with trabeculectomy and was minimum after nonpenetrating trabeculectomy alone. Thus, induced astigmatism was greater after trabeculectomy than nonpenetrating one. Nonpenetrating trabeculectomy appeared to be safer because of lesser effect to corneal endothelium. LA: Japanese
