Sferic rgp
Spherical lenses (multi-curve, spherical-aspherical and aspherical) are indicated in the different morphological conditions to compensate for simple ametropies and astigmatisms up to 1,75 diopters. For each, the edge is realized with an exclusive design to favor the comfort, minimizing the mechanical interaction in winking.
three curve
Indicated on corneas with e = 0,45, it allows an easy interpretation of the fluoroscopic pattern and a coverage ratio of 80-85% on the HVID. Suggested diameter selection from 9,40 to 10,20 mm.
S2
The small spherical BOZD and the parabolic periphery (lift=60µm) allow the adaptation on normo-aspherical corneas and in early keratocons.
Basf
Design sferico con periferia asferica, adatto in cornee a ipo-eccentriche (e ≤ 0,30) per ottimizzare la stabilità. Si suggerisce la tecnica applicativa intra-palpebrale, con diametro totale ≤ 9,60mm e clearance apicale di 10÷15µm.
basf aspheric variant
Spherical design with aspherical periphery, suitable in hypo-eccentric corneas (and 0.30) to optimize stability. The intra-eyelid application technique is suggested, with a total diameter of 9.60mm and an apical clearance of 10-15µm.
elliptic
Dual-conic model with asphericity of 0,30 ideal on medium eccentricity corneas (e 0,45); The back eccentricity is susceptible from 0,30 to 0,60 depending on the topographical pattern.
qual
Sphere-Aspheric (e = 0,50) evolving transition for better alignment; it is recommended the use of high Dk polymers, diameters ranging from
9,00 to 10,20mm.
