Results of a study conducted at the University of Melbourne in Australia show the Menicon Menifocal Z alternating vision, concentric, bifocal, GP lens can be safely worn for up to 30 days of continuous wear.

Researchers followed 35 existing GP wearers over a six-month period, 27 of whom completed the study.

Adverse responses and lens binding were minimal and no significant increase in corneal staining, vascularization or superior palpebral conjunctival papillae was noted.

They concluded that the hyper-Dk tisilfocon A material allows for safe wear of the lenses on a continuous-wear basis.

The study appears in the December issue of Optometry and Vision Science (Lakkis C, Goldenberg SA, Woods CA. Investigation of the performance of the Menifocal Z gas-permeable bifocal contact lens during continuous wear. Optom Vis Sci 2005;82:1022-1029).
