Miru 1month Menicon for Astigmatism

To see, is to discover.
To see, is to be moved.
To see, is to laugh.
To see, is to question.
To see, is to understand.
To see, is to share.

From the time we open our eyes in the morning,until we close them again at night,our days-and our lives-are defined by what we see.

That's why we chose Miru-a Japanese word meaning "to see"-as the global brand name for our visionary new range of contact lens products.

Together with the other products in the Miru line,they are designed to change the way you see the world forever.

Miru
by Menicon

key Characteristics

1month Miru is designed with balanced properties which support our aim to provide the best possible monthly contactlens for both eye care practitioners and their patients. Offers the best possible wearing experience for patients whilst providing an exceptional level of safety.

  • Low Bacterial Adhesion

  • Optimal Corneal Oxygenation

  • Minimal Lipid Deposition

  • Minimal Sensitivity

Low Bacterial Adhesion

SAFETY FIRST

Menicon has developed a unique and highly sophisticated surface technology as part of its ongoing aim to provide a safer and cleaner contact lens wearing experience. 1month Miru,asmofilcon A material demonstrated the lowest level of bacterial adhesion to the lens surface when compared with five commercially available silicone hydrogel contact lenses,

Optimal Corneal Oxygenation

OXYGEN TRANSMISSIBILITY

1month Miru silicone hydrogel contact lens has one of the highest levels of oxygen transmissibility(161 DK/t)amongst all commercially available today. It is well above that recommended for safe daily and even extended wear of contact lenses. Furthermore, Menicon has focused on a material and lens design combination that provides a constant higher level of averaged oxygenation across the entire cornea surface. Such attention to balancing design and material is key to providing a safer lens wearing experience.

Maximum corneal oxygenation across the relevant areas of the lens and over the entire pwer range

Minimal Lipid Deposition

RESISTANCE TO LIPID DEPOSITION

1month Miru has agreater resistance to lipid deposition in comparison to five other popular silicone hydrogel contact lenses. the greater resistance to deposition found with 1month Miru is likely to result in lower levels of discomfort, visual disturbances, inflamation of the oculay surface and lens spoilation in comparison to the other silicone hfdrogel contact lenses that were examined.

Method: SiHLs were immersed in 1.5mL malten Pharmasol* for 3hrs at 60°C, rubbed with MeniCare Soft multipurpose solution (Menicon) 20 times. Subsequently, lipid deposition resitance was visually assessed at riin tenperature.
*Pharmasol, a wax-like compound,was used as amarker for lipid deposition.

Minimal Sensitivity

THE EFFECT OF COSMETIC REMOVERS

Contact lenses are frequently used in conjunction with other face and eye cosmetic products,which an produce some sensitivity problems. However, 1month Miru has shown minimal sensitiviy in such circumstances. An in-vitro study investigated the effect of cleansing agents on 1month Miru and other silicone hydrigel lenses. Overall, a greater swelling rate was observed when lenses were soaked in cleansing oils in comparison to lenses soaked in cleansing gels, although this difference was negligible for asmofilcon A and lotrafilcon B lenses. Differences between lenses in swelling rate due to deposition and absorption of eye cosmetics might be related to differences in hydrophilic characteristics between lenses. The results of this study should help eye care practitioners in selecting the most appropriate contact lens to minimize deformation, degeneration and swelling of silicone hydrogel contact lenses due to deposition and absorption of cleansing agents. Additionally,the results of this study also highlights the importance of removing contact lenses before the use of cleansing agents.

TORIC DESIGN

Thinner back toric design

Double vertical asymmetric slab-off*

  • To harness the naturallid force

Horizontal(Right and Leff) peripheral ballast

  • Prism free optic zone(O.Z.)
  • Independent peripheral design from O.Z.

Anatomic profile

The eyelids natural coverage of the cornea is asymmetric where theupper lid covers more of the cornea than the lower lid.

The double vertical slab off fits to the asymmetric lids anatomy to prevent axis ratation and to optimise lens centration.

NOTE

TIP: Because of the vertical asymmetric design, 1month Miru for Astigmatism should be placed in the eye with the number 6logo at the top, and the axis guide mark at the bottom.
