Abstract
Multipurpose contact lens care products have been developed to provide wearers with simpler lens care regimens. Although previous studies have shown that the multipurpose products can be formulated without increasing the risk of irritation or other adverse reactions, questions still remain regarding the effectiveness of multipurpose products that are labeled with cleaning indications. The following is a report of a 3-month study conducted to compare two approved surfactant contact lens cleaning products (Bausch & Lomb® ReNu® Multi-Purpose Solution and Alcon® Opti-Clean® II Daily Cleaner) when used in the care of soft (hydrophilic) contact lenses worn for daily or extended wear. Patients ( N = 181) used the study surfactant lens cleaning products in conjunction with their current lens care regimens in a paired-lens, left-eye/right-eye comparison. Quantitative analysis of lens protein uptake levels (ninhydrin test) and microscopic examination showed no significant differences between lenses cleaned with the ReNu Multi-Purpose Solution and the Opti-Clean II Daily cleaner. We conclude that the clinical performance of the ReNu Multi-Purpose Solution is equivalent to that of the Opti-Clean II Daily Cleaner.
