Effect of a single-piece aspheric hydrophobic acrylic intraocular lens design on centration and rotation.

Purpose: To assess the rotation and centration stability of the new design features of a 1-piece aspheric hydrophobic acrylic intraocular lens (IOL).

Setting: National Eye Hospital, Cairo, Egypt.

Design: Randomized clinical trial.

Visual performance of the Tecnis one-piece lens ZCB00.

Synopsis: The aspheric, one-piece design of the Tecnis® ZCB00 intraocular lens provided higher mesopic contrast sensitivity and relatively constant refraction at different pupil sizes compared to the Sensar® AR40e.

Purpose: Comparing the impact on functional vision of the aspheric Tecnis® ZCB00 one-piece lens compared to the spherical Sensar® AR40e three-piece lens.

Setting: National Eye Hospital, Cairo, Egypt.
