Topography-Guided Refractive Astigmatism Outcomes: Predictions Comparing Three Different Programming Methods.

Purpose: To identify the laser programming strategy that will achieve optimal refractive outcomes of LASIK with a topography-guided laser for eyes with a disparity between cylinder measured by manifest refraction and cylinder measured by topography.

Setting: Six surgeons at 5 clinical sites in the USA.

Design: Retrospective data review.

A novel terminal web-like structure in cortical lens fibers: architecture and functional assessment.

This study describes a novel cytoskeletal array in fiber cells of the ocular lens of the rat and shows its relationship to the classical terminal web of other epithelial tissues. Naive adult Sprague-Dawley rats (n = 28) were utilized. F-actin, fodrin, myosin IIA, and CP49 distribution was assessed in anterior and posterior polar sections.
