✦ Synopsis

Objective: a study was conducted at the University of Houston College of Optometry to test the efficacy of two multi-purpose and one two-step patient care systems in the disinfection and storage of diagnostic soft contact lenses. St&y design: the solutions investigated were OPTI-ONE TM, COMPLETE'@, and Quick CAREm, which contain polyquad/citrate, trischem, and isopropyl alcohol respectively. Solutions from 60 vials containing recently used diagnostic soft lenses were tested for initial bacterial growth and the organisms identified. The lenses were then cleaned and disinfected according to the manufacturer's instructions. The solution from each vial was then tested for bacterial growth at the manufacturer's minimum recommended length of time for disinfection and subsequently at weekly intervals for 4 weeks. Results: growth was significantly greater with OPTI-ONETM than with COMPLE'IE" or Quick CARE TM. Serratia marcescens was the organism most frequently found. Conclusion: COMPLETE@ and Quick CARETM appear to be efficient and efficacious systems for in-office disinfection of diagnostic soft lenses.
