Menicon Z Night

Indications

Menicon Z Night lenses are worn at night to flatten the cornea into a more spherical shape.
Myopia and/or astigmatism is corrected after the first night with stable vision achieved within a week.

Menicon Z Night lenses are indicated in the following cases :
Menicon Z Night
• Myopia ≤ -4.00 D
• With-the-rule astigmatism ≤ 1.50 D
• Against-the-rule astigmatism ≤ 0.75 D

Menicon Z Night Toric
• Myopia ≤ -4.00 D
• With-the-rule astigmatism ≤ 2.50 D
• Against-the-rule astigmatism ≤ 1.50 D

Advantages

1. Freedom from visual correction during the day and the ability to enjoy excellent vision to undertake all sorts of activities.
2. Minimized allergy and dry eye problems and no more dust particles.
3. The safety of wearing Menicon Z night lenses with maximum corneal oxygenation (hyper Dk Menicon Z material) is assured.
4. Right and left lenses are provided in different colours to avoid mistakes

Lens Design

Menicon Z Night is a reverse geometry contact lens.
The base curve is responsible for flattening the central cornea and thus reducing myopia.
The reverse curve is the link between the central and tangential peripheral parts of the lens.
The tear reservoir zone is located in the reverse curve, which, together with the three fenestrations, allows optimum tear exchange. The tangential curve allows adequate centration of the lens on the eye.
