The hybrid contact lens AirFlex is available in different geometries: 
- spherical back surface with aspherical flattening
- Uni- or multifocal with spherical optical zone on the front surface
- toric back surface with aspherical flattening
- Uni or multifocal with torical optical zone on the front surface
- Ballast stabilisation
- spherical back surface with aspherical flattening
- Uni- or multifocal with toric optical zone on the front surface
- Multi-dynamic stabilisation
- toric back surface with aspherical flattening
- Uni- or multifocal with spherical optical zone on the front surface
- Ballast stabilisation
The skirt and center are modifiable. It is important to note that the fitting of the skirt is totally independent of the central zone and does not have any influence on the vision. The skirt should be perfectly aligned with the conjunctiva. Flattening of the soft skirtThe soft peripheral skirt can be adjusted to improve the fitting concerning centration and mobility. 4 different skirt are available. 
Multifocal design:Simple Progressive (Sp): concentric spheric/aspheric central zone. With distance (CD) or with near in center (CN).

Tekniske data:
Total diameter: 14.90 mm and 15.50
Base curve: 5.50 to 10.00 mm
Sphere: -40.00 to + 40.00 dpt
Cylinder: -0.50 to -6.00 dpt

Indications of hybrid contact lenses are:
Wearers of RGP lenses having problems relating to comfort, centration or stability
Keratoconus and other corneal irregularities, including highly complex irregular corneas
All astigmatisms that can potentially be fitted with RGPs
All high ametropias
Wearers of Piggyback lenses
Unilateral or occasional wear
First fitting/Fitting Guide
Total diameter: = 14.90 mm
Basiskurve = flattest K reading or base curve of “RGP-trial lens” (recommended)
Power: eyeglasses sphere (Vertex power = 0)
Addition: Addition of glasses
Zoc, position: dominant eye CD, non-dominant eye CN
Flattening: first try with J = 0,0
Assess the fit
Control visual acuity:
If visual acuity is insufficient, perform a spherical over-refraction and compensate for Vertex distance to determine final lens power.
Evaluate the fit during a slit lamp exam:
As in soft contact lens fitting, the evaluation is based on:
Centration
Mobility
Fluorescein at lens removal
Verify the alignment of the lens using large molecule fluorescein. Never use fluorescein for RGP lenses as this may damage the hybrid lenses. |
