Geometry

  • Spherical front and back optic zones
  • Spheric flattening

Base curve calculation for the first contact lens

We recommend you choose the diameter of the lens by adding 2.00 mm to the HVID.

  • Diameter 13.00 mm = flattest K + 0.50 mm
  • Diameter 13.50 mm = flattest K + 0.70 mm
  • Diameter 14.00 mm = flattest K + 0.90 mm
  • Diameter 14.50 mm = flattest K + 1.10 mm
  • Diameter 15.00 mm = flattest K + 1.30 mm

Addition

3 Progressive Power Profiles:

  • A, B and C covering a range of additions from +0.50D to +2.75D
  • Chosen based on required reading addition and age to ensure the optimum Progressive Power Profile for visual requirements and pupil size

 

Adaptation Checklist

1. Insert the lens for between 30 minutes and 2 hours. Make an over-refraction
2. Biomicroscopy (× 10 to 15) white light: observe the lens with the patient looking straight ahead and during eye movement
3. Test mobility by eyelid movement (Push up test)
4. Movement of the lens should be from 1 to 2 mm downwards
5. Check the appearance of the front optic zone: tear film, hydration, lubrication, deposit
6. Check keratometry on the contact lens: (deformation of the mires)
7. Check for corneal and conjunctival staining with fluorescein after lens removal
8. Order the final lens based on the SN

ES70 Material

Through intensive trials and research, ES70 has been proven to be one of the safest soft lens materials available. ES70 is versatile too and can be effectively used for the correction of all types of visual defects.

Outstanding Oxygen Permeability

Material oxygen permeability is an important parameter to consider when fitting any contact lens. For soft lenses, material permeability is related to its water content. The higher the water content the lower the DK value.

However, while the ES70 material used for Lunelle lenses has a hydrophily of 70%, it simultaneously achieves a permeability (Dk) four times higher than that of HEMA and twice as high as that of a material with 55% hydrophily.

ES70 is a non-ionic material. This means Lunelle lenses are resistant to deposits. Fewer lens deposits means better visual quality, improved comfort and the optimisation of oxygen supply throughout the life of the lens.

All Day Comfort

Great Vision Throughout the Day 

All Lunelle lens designs enable good mobility. This allows an excellent flow of tears between the lens and the eye and ensures optimal ocular health. This 'pumping' effect also contributes to a higher oxygen supply. When this is combined with ES70s high water content the metabolism of the eye remains practically unaffected, so patients can enjoy great comfort and vision all day.
