We are interested in the influence of trabeculectomy (TE) with releasable sutures to corneal curvature in the early postoperative period. 35 eyes of 31 patients were followed after operation. Corneal topography was made on the Topograph Opticon 2000 one day before, 1st day, 1st week, 1st month and during 6 - 12 months after operation. Astigmatism after operations was the highest on 1st day +3,7 D, which means elevation of about +2,8 D. During 1st month postoperative astigmatism was decreased by about 2,0 D, it is about +0,8 D more than before operation. During 6 - 12 months after operation temporary astigmatism nearly disappears, it only makes +0,25 D. The axis of astigmatism was without larger alterations. Small temporary changes were seen according to the place of TE. Temporary astigmatism was observed immediately after the extraction of the releasable sutures. Astigmatism after operation was influenced by the rate of filtration during the short postoperative time and also after extraction of the releasable suture.
Key words: astigmatism, intraocular pressure (IOP), corneal topography, trabe - culectomy with releasable sutures
