Bausch + Lomb: Biotrue Multi-purpose Solution

Biotrue™ helps make wearing contact lenses easier on your eyes*

Biotrue is formulated to work like your eyes. By studying how the eye naturally works to clean, hydrate, and keep itself healthy, Bausch + Lomb developed a unique and innovative solution to provide outstanding care for soft contact lenses.

Biotrue goes beyond cleaning by bringing together three bio-inspired innovations:

  • Has a lubricant found naturally in your eyes
  • Matches the pH of healthy tears
  • Keeps certain beneficial tear proteins active

Maybe that's why Biotrue is the solution preferred 3:1 over the leading multi-purpose solution1

Biotrue provides superior disinfection:2

Biotrue combines a dual disinfection system with the unique bio-inspired attributes of a pH equal to healthy tears and protein management, to provide unsurpassed disinfection.

Biotrue provides up to 20 hours of moisture in every drop:3

Biotrue hydrates contact lenses in a way that eyes stay hydrated — by utilizing hyaluronan (HA), a lubricant found throughout the body.

Biotrue matches the pH of healthy tears:

Eyes that are healthy continually create the perfect environment. That's why Biotrue is uniquely formulated to match the pH of healthy tears — maintaining the eye's natural condition and enabling optimal activation of our dual disinfectants.

Biotrue keeps certain beneficial tear proteins active as they are naturally in the eye:

  • Proteins in their native state act as the eye's inborn germ-fighters, carrying out antimicrobial activities on their own.
  • Proteins that are denatured have lost their structure due to factors such as external stresses. Biotrue lifts and removes denatured proteins.

* : Based on patient use study.

1: Based on a study of 130 patients who used both Biotrue and Opti-Free RepleniSH.

2: Results of in vitro study following FDA/ISO stand-alone procedure for disinfecting products modified with organic soil added to create a more rigorous test condition. Primary criteria for effective disinfection are defined as a reduction in the number of bacteria by a minimum of 3 logs (99.9%) and a reduction of mold and yeast by a minimum of 1 log (90%) within the recommended disinfection time. Competitive multi-purpose solutions tested included AMO COMPLETE Easy Rub, Alcon OPTI-FREE Express and Alcon OPTI-FREE RepleniSH

3: "A 20 hour wetting agent release study was conducted in order to determine how much wetting agent(s) were left on contact lenses at periodic time intervals up to 20 hours. The study performed was very similar to a study conducted with renu fresh. Various lens care solutions were tested (Buffer, Clear Care, Opti-Free Replenish, Biotrue, renu fresh and renu sensitive). Procedure: Lenses were soaked in contact lens disinfecting solution (CLDS) or buffer for 8 hours then rinsed with buffer solution for 20 hours at a rate that approximates tear film secretion. Rinse solution was collected at various intervals and the surface tension of the diluted samples were measured. A t-Test was performed on paired data to evaluate statistical differences in surface tensions among CLDS-soaked and HBSS-soaked lenses. The extended presence of wetting agents in the CLDS-soaked lens rinse solutions as indicated by a reduction of surface tension relative to HBSS-soaked lens surface tensions demonstrates that surfactants are retained and released by contact lenses. Statistical differences in the surface tensions between rinse solutions from the various lens/CLDS combinations also indicate differences in the length of time wetting agents are released among the lens/CLDS combinations"
