We evaluated the relationship between corneal astigmatism and the distance of corneal incision from the visual axis after temporal clear-cornea incision stitchless cataract surgery with phacoemulsification and aspiration. The postoperative astigmatism averaged 0.15 diopters (D) in 228 eyes with 3.0-mm incision and 0.4D in 116 eyes with 3.8-mm incision 3 months after surgery. There was no significant difference between astigmatism and the distance of corneal incision from the site of the visual axis in the central cornea. Since the distance is closely correlated with the corneal diameter, the findings show that the corneal diameter is not the major factor for astigmatism after cataract surgery.
