Frequency of Contact Lens Complications Between Contact Lens Wearers Using Multipurpose Solutions Versus Hydrogen Peroxide in the United States and Canada.

Objectives: To retrospectively compare frequency of contact lens (CL) complications in soft CL users of hydrogen peroxide (H2O2) and multipurpose solutions (MPS).

Methods: This was a multicenter, retrospective chart review of CL records from each patient's three most recent eye examinations at academic and private practices. Patients must have used the same solution type for at least 3 years.

Impact of the 2011 International Workshop on Meibomian Gland Dysfunction on clinical trial attributes for meibomian gland dysfunction.

Purpose: The 2011 International Workshop on Meibomian Gland Dysfunction was organized to build consensus on various disease aspects of MGD. The purpose of this review was to examine the influence of the MGD Workshop on clinical trials by examining their attributes prior to and after the Workshop.

Methods: A search for clinical trials using the terms "Meibomian Gland Dysfunction" was conducted using the "Interventional Studies" filter on ClinicalTrials.

Matching the LenStar optical biometer to A-Scan ultrasonography for use in small animal eyes with application to tree shrews.

We describe an analysis strategy to obtain ultrasonography-matched axial dimensions of small animal eyes using the LenStar biometer. The LenStar optical low-coherence reflectometer is an attractive device for animal research due to its high precision, non-invasiveness, and the ability to measure the axial dimensions of cornea, anterior chamber, lens, vitreous chamber, and axial length. However, this optical biometer was designed for clinical applications in human eyes and its internal analysis provides inaccurate values when used on small eyes due to species-dependent differences in refractive indices and relative axial dimensions.
