The Lunelle ES70 Sphere (Spherique) is a custom soft contact lens for all spherical refractive errors. Its wide range of parameters and the unique ES70 material allows optimal adaptation to the eye and therefore offers excellent, all-day comfort.
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
Insert the trial lens and leave for between 30 minutes and 2 hours. Over refraction (you can use the autorefractometer for getting an idea of cyl/axis)
Biomicroscopy (× 10 to 15) white light: observe the lens with the patient looking straight ahead and during eye movement
Check mobility by eyelid movement (push up test)
The sag of the lens should be from 1 to 2 mm downwards
Check the appearance of the front optic zone: tear film, hydration, lubrication, deposit
Check the keratometry on the contact lens: (deformation of the mires)
Check for corneal and conjunctival staining with fluorescein after lens removal
Order the final lens based on the SN
Lunelle ES70 Material, the optimal solution for eye health and safety since the '80s.
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.
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.
Lunelle material - never beaten
The ES70 Material Composition
The ES70 material used for Lunelle contact lenses is composed of PMMA, which makes it robust and transparent, and PVP, which ensures a stable water content. The production of ES70 material will continuous after the take over by SwissLens. The same laboratorie will produce the row material and blank as before and exclusively availalbe for the Lunelle Products from SwissLens. The material involves the use of the most advanced techniques to obtain the stable material. The development of Essilor's polymerisation technology has proven to provide a very consistent material quality.
PRODUCTION SwissLens uses a high-tech lathing technique to achieve optimum reproducibility. Lunelle contact lenses are systematically inspected at all stages to ensure that the parameters remain the same in the dehydrated state QUALITY GUARANTEE The material and the contact lenses are produced in accordance with the strict rules laid down by Quality Assurance. This is an independent quality assurance service at Essilor, which ensures consistent product quality.
