Wavefront-guided PRK treatment of myopia using a refractive aberrometer.

Purpose: To evaluate the safety, effectiveness, and patient-reported outcomes of wavefront-guided photorefractive keratectomy (PRK) for the correction of myopic refractive errors with and without astigmatism.

Setting: U.S.

Evaluation of Intraocular Lens Rotational Stability in a Multicenter Clinical Trial.

Purpose: To evaluate the postoperative rotational stability of two prototype intraocular lens (IOL) designs (subsequently termed version 1 and version 2).

Patients And Methods: A prospective, multicenter, randomized, paired-eye, 6-month study evaluated the version 1 and version 2 IOLs. Results were compared with a control IOL (TECNIS toric 1-piece monofocal IOL) evaluated in a separate, similarly designed study.

Visual outcomes and safety of an extended depth-of-focus intraocular lens: results of a pivotal clinical trial.

Purpose: To compare the effectiveness and safety of the TECNIS Symfony intraocular lens (IOL; ZXR00) with the TECNIS 1-piece monofocal IOL (ZCB00).

Setting: 15 sites in the United States.

Design: Prospective, randomized, patient-masked/evaluator-masked clinical trial.
