Optimization of surgical parameters based on patient-specific models: Application to arcuate keratotomy.

Purpose: To determine surgical parameters for arcuate keratotomy by simulating the intervention with a patient-specific model.

Setting: University Eye Clinic Salzburg, Paracelsus Medical University, Austria, and Institute for Surgical Technology and Biomechanics, University of Bern, Switzerland.

Design: Computational modeling study.

Intraocular Pressure Course During the Femtosecond Laser-Assisted Cataract Surgery in Porcine Cadaver Eyes.

Purpose: Femtosecond laser-assisted cataract surgery (FLACS) is an increasingly common procedure. Most laser systems require corneal applanation and thereby increase intraocular pressure (IOP). The purpose of the present study was to evaluate the IOP changes that occur during the FLACS procedure performed using the Catalys femtosecond laser system.

Reliability of automatic biometric iris recognition after phacoemulsification or drug-induced pupil dilation.

Purpose: To investigate the reliability of a biometric iris recognition system for personal authentication after cataract surgery or iatrogenic pupil dilation.

Methods: This was a prospective, nonrandomized, single-center, cohort study for evaluating the performance of an iris recognition system 2-24 hours after phacoemulsification and intraocular lens implantation (group 1) and before and after iatrogenic pupil dilation (group 2).

Results: Of the 173 eyes that could be enrolled before cataract surgery, 164 (94.
