Cytotoxicity and effects on metabolism of contact lens care solutions on human corneal epithelium cells

Purpose: The aim was to determine the cytotoxic effects of three multipurpose solutions (MPS) on human corneal epithelial cells (HCEC) and to assess the metabolic rates of recovering cells at different levels of cell membrane damage.Method: The effects of one to 15 minutes exposure to multipurpose solutions containing polyquaternium‐1 (MPS‐A), polyaminopropyl biguanide (MPS‐B) and polyhexanide (MPS‐C) on HCEC were determined. Recovery rates at...
