Abstract:
We describe a technique for making an optimal flange in intraocular lenses (IOLs) used for flanged intrascleral IOL fixation. The flange shape varies in poly(methyl methacrylate) (PMMA) haptics of different IOLs of different manufacturers. We identified the distance between the forceps grip of the haptic and the end of the haptic during heating with a cauter as a critical factor for the optimal flange shape in 5 PMMA haptics but not in 2 polyvinylidene fluoride haptics.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Band broadening refers to spreading solute bands as they travel through the column. This broadening can impact resolution. Plate height (H) represents the length required for one theoretical plate. A lower plate height corresponds to...
