Comparison of different types of phacoemulsification tips. III. Morphological changes induced after multiple uses in an ex vivo model.

Purpose: To assess the ultrastructural morphologic changes in the surface's micro-roughness for single-use and multiple-use phaco tips after multiple phacoemulsification cycles in an ex vivo animal model.

Setting: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA.

Comparison of different types of phacoemulsification tips. II. Morphologic alterations induced by multiple steam sterilization cycles with and without use of enzyme detergents.

Purpose: To evaluate the alterations in the morphology and elemental composition of reusable phacoemulsification tips after cleaning and sterilization.

Setting: John A. Moran Eye Center, Salt Lake City, Utah, USA.

Comparison of different types of phacoemulsification tips. I. Quantitative analysis of elemental composition and tip surface microroughness.

Purpose: To evaluate the elemental composition of phacoemulsification tips and their surface roughness in the microscale.

Setting: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA.
