Testing the wearability of the N&N Menicon soft contact lens

Forty-four patients were fit with N & N Menicon Soft Contact Lenses for future approval of the lenses by the Food and Drug Administration. Eighteen patients utilized chemical sterilization (Burton Parsons Flexol) and nineteen used heat (Meniconilizer). Seven patients were released from the study for personal reasons. No patients were discontinued from lens wear due to objective or subjective symptoms. Twenty patients were monitored and decreases in tear pH, tear flow, and tear break up time were noted at the end of six months wear. Anterior segment photographs were taken on twenty- three patients to document any changes in limbal vascularization and only minimal changes were found. We found the N & N lenses to be excellent, particularly in achieving visual acuity and in ease of patient handling
