Copyright policy )[Corneal astigmatism following trabeculectomy].
The study was designed to investigate the change of corneal astigmatism following trabeculectomy.Before and after the operation at different periods, the corneal astigmatism of 42 eyes was evaluated by Topcon-OM-3 keratometer.Almost the corneal astigmatism of all the cases was with-the-rule in the early stage after trabeculectomy. Among them, the astigmatism in 41.03% of cases was more than 2.00D, 3 months post-operatively 17.50% shifted towards against-the-rule, and 9.50% remained more than 2.00D which was induced by the surgery.Trabeculectomy may cause certain with-the-rule corneal astigmatism. The corneal astigmatism in most of the cases may decrease as time passes by.
