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).
Launched "Menicon 1day", a daily disposable soft contact lens in the Japanese market on July 1st 2005. Menicon 1day is manufactured by liquid edge moulding technology on 55% water content Ocufilcon D material resulting in a lens with exceptional dimensional stability and smooth edges. The mid water, tinted blue content lens provides excellent image quality, lasting comfort, easy handling and the convenience of wearing a new pair of lenses everyday.
By adding two new products, Menicon has now completed its range of soft and RGP contact care products.
Menicon launched two new contact lens care products, MeniCare© Soft and MeniTears© in June 2005 during the British Contact Lens Association 29th Clinical Conference and Exhibition in Brighton, United Kingdom. Initially, these two products are marketed in Europe and Asia and will be soon sold in the rest of the global markets.
MeniCare© Soft with Comfortec™ is a polyhexanide-based multipurpose disinfecting solution combined with four ideally balanced complementary agents. It is compatible with all soft contact lenses and provides a high spectrum of antimicrobial activity, low toxicity, and excellent comfort.
MeniTears© is a preservative-free lubricant eye drop, packed in single doses, which provides instant relief, continuous hydration and end-of-day comfort to contact lens wearers. The mechanism of action of MeniTears relies on its wetting agent, carboxymethylcellulose, and its patented hypotonic electrolyte formula. MeniTears eye drops are recommended for all soft, rigid gas permeable and silicone hydrogel contact lenses. MeniTears is manufactured by Advanced Vision Research, an internationally recognized ophthalmic drug manufacturer, which was made possible as a result of the strategic alliance between the two companies.
"The launch of these products is an important addition to our existing line of Menicon products to enable us to reach a wider variety of consumers", said Dr Hidenari Tanaka- President of Menicon Co., Ltd.
Menicon now has a complete range of contact lens care products (i.e. MeniCare Soft, MeniTears, MeniCare Plus and Progent) for all soft and rigid gas permeable contact lenses.
Menicon entered the Chinese market last year with MeniFlex IntraOcular Lens and now has a complete range of RGP Lens and Care products
(i.e. Menicon Z, MeniCare Plus Multipurpose Solution and Progent Protein Remover), expected to be launched to the Chinese market in June 2005.
<*> MeniconZ is the world's only Hyper DK RGP approved by FDA for up to 30 days continuous wear.
