The Ability of a Virtual Implantation Device to Evaluate Two Intraocular Lens Designs.

Purpose: To evaluate the ability of a novel device using virtual implantation to compare the visual performance of two different types of intraocular lenses (IOLs).

Methods: In this prospective, masked, and randomized clinical trial, the visual performance of monofocal and lowadd bifocal IOLs was compared using a device for virtual implantation called VirtIOL. Eighty patients (< 50 years old with healthy eyes and without cataract) were enrolled in this study.

Prediction of visual outcomes using virtual implantation of a trifocal intraocular lens in presbyopic lens exchange patients.

Purpose: To assess the reliability of a new virtual intraocular lens (IOL) implantation device to predict the outcomes of a trifocal IOL.

Setting: Clinical sites in Spain and Germany.

Design: Prospective multicenter study.

Photorefractive Keratectomy in Experienced U.S. Naval Aviators: A Prospective Evaluation.

Purpose: To report on the prospective evaluation of photorefractive keratectomy (PRK) in experienced ametropic naval aviators that led to the approval of refractive surgery for military pilots.

Methods: This was the first study evaluating refractive surgery in naval aviators. Return to flight status after PRK and clinical outcomes and subjective and objective flight performance were evaluated.

Immediate Sequential Bilateral Cataract Surgery in Patients with Bilateral Visually Significant Cataracts.

Purpose: To report our experience of performing immediate sequential bilateral cataract surgery (ISBCS) in patients with visually significant cataracts and reduced preoperative corrected distance visual acuity (CDVA).

Methods: Data of patients who underwent ISBCS for visually significant cataracts and had preoperative CDVA ≤20/32 (≤0.2 logMAR) in each eye were retrospectively reviewed.
