Three-year outcomes of mixed astigmatism correction with single-step transepithelial photorefractive keratectomy with a large ablation zone.

Purpose: To evaluate refractive and visual outcomes of single-step transepithelial photorefractive keratectomy (transPRK) in the treatment of mixed astigmatism with the use of an aberration-neutral profile and large ablation zone.

Setting: Nicolaus Copernicus University and Oftalmika Eye Hospital, Bydgoszcz, Poland.

Design: Retrospective, observational case series.

Air-Puff-Induced Dynamics of Ocular Components Measured with Optical Biometry.

Purpose: To analyze the dynamics of all optical components of the eye and the behavior of the eyeball under air-puff conditions in vivo. To determine the impact of the intraocular pressure (IOP) on the air-puff-induced deformation of the eye.

Methods: Twenty eyes of 20 healthy subjects were included in this study.
