The Miru 1Month Menicon is a monthly replacement silicone hydrogel contact lens designed for daily wear. It is manufactured by Menicon, a Japanese company known for its innovative contact lens technologies. These lenses are engineered to provide high oxygen permeability, comfort, and eye health over a month of use. The Miru 1Month Menicon contact lens series obtained U.S. Food and Drug Administration (FDA) approval in February 2018.

Key Technologies of Miru 1Month Menicon:

1. MeniSilk™ Technology:

• This proprietary silicone hydrogel material (Asmofilcon A) offers ultra-high oxygen transmissibility (Dk/t = 161), ensuring adequate oxygen supply to the cornea. It also maintains balanced water content (40%) for hydration and comfort.

2. NanoGloss™ Surface Treatment:

• Provides a super-smooth lens surface, reducing bacterial adhesion and lipid deposits. This enhances comfort, minimizes irritation, and supports cleaner lens wear.

3. Thin Edge Design:

• The lens edge profile is uniform across all power ranges, ensuring consistent comfort and reducing friction during blinking.

Key Features of Miru 1Month Menicon:

1. Advanced Material Technology

MeniSilk™ Silicone Hydrogel Material:

• High Oxygen Permeability (Dk/t = 161): Ensures optimal corneal oxygenation, reducing the risk of hypoxia and maintaining eyes in a “fresh, white, and healthy” state even during extended wear.
• Balanced Water Content (40%): Provides hydration without excessive drying, enhancing comfort.

NanoGloss™ Surface Treatment:

• Super-Smooth Surface: Reduces bacterial adhesion and lipid deposits by up to 100% (when used with MeniCare Soft solution), minimising infection risks and maintaining lens cleanliness.
• Low Friction Design: Ensures comfortable blinking (~28,000 times daily) by allowing eyelids to glide effortlessly.

2. Comfort-Optimized Design

Thin Edge Profile:

• Uniform Thickness Across All Powers: Eliminates comfort differences between eyes, regardless of prescription strength.
• Light Blue Handling Tint: Improves visibility during lens handling.

3. Health and Hygiene Focus

• Bacterial Adhesion Resistance: Demonstrates the lowest level of bacterial adhesion compared to other silicone hydrogel lenses, supporting long-term eye health.
• Deposit-Free Performance: 100% deposit-free findings reported in follow-up studies when used with MeniCare Soft solution.

4. User-Centric Benefits

• Ideal for Long-Term Wearers: Combines high oxygen transmission with moisture retention, reducing dryness and irritation.
• Versatility: Caters to diverse vision needs (sphere, toric, multifocal) with consistent comfort across all variants.
• Replacement Schedule: Designed for monthly use (30 days) with daily wear only (not for overnight use).
