Dry eye symptoms and impact on vision-related function across International Task Force guidelines severity levels in the United States.

Background: International Task Force (ITF) guidelines established a grading scheme to support treatment of dry eye disease based on clinical signs and symptoms. The purpose of this study was to assess the impact of dry eye on vision-related function across ITF severity levels using the Ocular Surface Disease Index (OSDI) questionnaire.

Methods: Non-interventional, cross-sectional study of prescription treatment-naïve dry eye patients seeking symptom relief at 10 ophthalmology and optometry practices.

Safety and effectiveness of a new toric presbyopia-correcting posterior chamber silicone intraocular lens.

Purpose: To evaluate the safety and effectiveness of the Trulign toric intraocular lens (IOL) in adults with cataract.

Setting: Eight private practices in the United States and 1 in Canada.

Design: Prospective randomized single-masked multicenter study.

Safety and effectiveness of a glistening-free single-piece hydrophobic acrylic intraocular lens (enVista).

Purpose: To evaluate the safety and effectiveness of a single-piece hydrophobic acrylic intraocular lens (IOL; enVista model MX60; Bausch & Lomb, Rochester, NY, USA) when used to correct aphakia following cataract extraction in adults.

Methods: This was a prospective case series (NCT01230060) conducted in private practices in the US. Eligible subjects were adult patients with age-related cataract amenable to treatment with standard phacoemulsification/extracapsular cataract extraction.
