Corneal sensation after small incision, sutureless, one-handed phacoemulsification.

Corneal sensitivity was measured in 60 eyes preoperatively and at one day, one week, and one month after small incision, sutureless, one-handed phacoemulsification performed by the same surgeon using the same technique. Corneal sensation remained normal at the center and the 3, 6, and 9 o'clock positions. Decreased corneal sensation was found over the width of the scleral tunnel incision at the limbus, extending in a wedge-shaped sector not encompassing the central cornea.
