Topographic analysis of early changes in corneal astigmatism after manual small incision cataract surgery without suture and with single radial suture using computerized videokeratography

The eyes with single radial anchoring suture tied over sclerocorneal tunnel incision demonstrated mainly with the rule type of astigmatism in early postoperative period, that is steepening in the meridian that intersects the incision. The eyes with sclero-corneal tunnel incision left without suture demonstrated mainly against the rule type of astigmatism in early postoperative period, that is flattening in the meridian that intersects the incision. Both the Groups with sclero-corneal tunnel incision showed a little induced astigmatism with Mean
