The effect of Gonioscopy on keratometry and corneal surface topography.

Background: Biometric procedures such as keratometry performed shortly after contact procedures like gonioscopy and applanation tonometry could affect the validity of the measurement. This study was conducted to understand the short-term effect of gonioscopy on corneal curvature measurements and surface topography based Simulated Keratometry and whether this would alter the power of an intraocular lens implant calculated using post-gonioscopy measurements. We further compared the effect of the 2-mirror (Goldmann) and the 4-mirror (Sussman) Gonioscopes.

Comparison of histopathologic features, clinical symptoms, and erythrocyte sedimentation rates in biopsy-positive temporal arteritis.

Purpose: To compare the histopathologic stage of temporal arteritis observed in biopsy-positive specimens with clinical symptoms and erythrocyte sedimentation rates (ESR). Also, to compare the degree of involvement of biopsies from the right versus left side in patients receiving bilateral biopsies.

Design: Retrospective case series.

Intraocular lens optic capture.

A continuous curvilinear capsulorhexis (CCC) provides a tear-resistant opening that allows use of a technique of capturing the intraocular lens (IOL) optic through the capsulorhexis opening when the opening is at least 1.0 to 2.0 mm smaller than the optic diameter.

The ability of periorbitally applied antiglare products to improve contrast sensitivity in conditions of sunlight exposure.

Background: Sun glare decreases athletes' contrast sensitivity and impairs their ability to distinguish objects from background. Many commercial products claim to reduce glare but have not been proven effective in clinical studies.

Objective: To determine whether glare-reducing products such as eye black grease and antiglare stickers reduce glare and improve contrast sensitivity during sunlight exposure.
