Acuvue Oaysis Contact Lens Wearers Being Refit Into P7 Contact Lenses

How Does PRECISION7® for Astigmatism Perform in Current and Successful Acuvue® Oasys for Astigmatism Wearers?

Determine the likelihood of successfully refitting a satisfied AOA CL wearers into P7A CLs

Study Overview

• Status: Recruiting
• Conditions: Contact Lens Comfort
• Intervention / Treatment: Device: Precision 7 contact lenses

Detailed Description

PRECISION7m for Astigmatism is a 1-week, silicone hydrogel (serafilcon A), daily wear, contact lens (CL) with extended wear approval made of a novel material that incorporates the Activ-Flo System. The Activ-Flo System has a moisturizing agent within the CL matrix, which allows for continual release of the moisturizing agents while also providing up to 16 hours of comfortable wear and precise vision for the life of the CL. While initial P7A data are promising, the literature currently lacks a targeted study aimed at determining how patients perform in P7A after transitioning out of other commonly prescribed silicone hydrogel CLs. This transition could be particularly important for patients who have astigmatism given that they tend to struggle with CLs more than spherical CL wearers.1 Thus, the purpose of this study is to determine the success rate of refitting current, satisfied ACUVUE OASYS for Astigmatism CL wearers into P7A. Understanding how a P7A CL wearer reacts to transitioning into P7A from AOA will provide valuable information to partitioners for patient educational purposes, and it will provide credence for refitting successful AOA patients into the newer P7A technology, which could help grow the P7A CL market by not limiting P7A refits to problem-solving events.
