Geometry
One geometry only, a 14.2 diameter on a median 8.6 base curve.
Optical design
Cylinder is supplied at two fixed powers, 0.65 D and 1.25 D, with sphere from -0.25 to -6.00 and +0.25 to +4.00.
Optics
Low Cylinder axes are limited to a fixed set of 15, 75, 90, 105, 165 and 180 degrees.
Stabilization
Orientation marks sit at 6 o'clock and 20 degrees off 6 o'clock on either side, for orienting the lens and reading rotation.
Fitting
The Low Cylinder design carries 0.65 D of cylinder and covers cylindrical corrections from 0.5 up to 1.0 D.
Note
Compensate rotation by Left Add, Right Subtract: rotation to the examiner's left is added to the refractive cylinder axis, rotation to the right is subtracted.
Material
Hioxifilcon D, a non-ionic copolymer of 2-hydroxyethyl methacrylate (HEMA) and glycerol methacrylate (GMA), cross-linked with ethylene glycol dimethacrylate (EGDMA).
Handling tint
Blue visibility handling tint, phthalocyanato (2) - (copper).
Replacement
Prescribable for frequent or planned replacement wear with cleaning, disinfection and scheduled replacement, disinfected on a chemical system.
Packaging
Supplied sterile in a sealed blister pack of buffered normal saline, labeled with base curve, power, diameter, manufacturing lot number and expiry date.
