Fitting advices for ToriFlex

Spectacle power must be converted into contact lens power (VD =0)

Total diameter: standard 9.50 mm

Bitoric Geometry (BT):

If astigmatism with the rule (WTR) flat K @ 0° ± 30°
- r0fl = rcfl – 0.05 / r0st = rcst + 0.05
- F’afl = Sph − 0.25 dpt
- F’ast = Sph + (-Cyl) + 0.25 dpt
If astigmatism against the rule (ATR) flat K @ 90° ± 30°
- r0fl = rcfl + 0.05 / r0st = rcst – 0.05
- F’afl = Sph+ 0.25 dpt
- F’ast = Sph + (-Cyl) – 0.25 dpt
If astigmatism oblique flat K @ 135° ± 15°/ 45° ± 15°
- r0fl = rcfl / r0st = rcst
- F’afl = Sph
- F’ast = Sph + (-Cyl)
Fronttoric prismatic (TP):
- r0 = rcfl – 0.05
- F’v: SphCL = Sph − 0.25 dpt / CylCL = (-Cyl) + ((rcfl-rcst)*5) / A°CL = A° glasses

Fitting advices for gas permeable contact lenses

Geometry

Insert trial lens for a minimum duration of 30 minutes. Ask patient to focus on the floor to minimise the foreign body sensation.
Evaluation of the subjective comfort.
Over-refraction
Slit lamp examination:
Dynamic evaluation with diffuse illumination:
- Eye in primary gaze and blinking normally.
- Movement (speed) and position after blink and during eye movements:
  - Vertical movement
  - Horizontal movement
  - Centration
  - A good fitting lens will be evenly centered on the cornea (±0.5 mm)
  - The movement should be pronounced but not too big (1-2 mm)

Static evaluation with fluoroscopy:
- Evaluation when patient is looking straight ahead and the lens is centered on the cornea without impact of the eyelids on the lens: Evaluation of the tear film thickness under the lens; tear film < 10μm = no florescein is visible.
  - central optic zone with alinement fluorescein pattern
  - inter-peripheral zone with small amount of fluorescein
  - peripheral zone with a band of increased fluorescein which will be needed for a good tear film exchange

Advice for Toriflex

The optimal fluorescein pattern shows a small fluor lake in the center and a larger fluor ring in the periphery (env. 0.75 mm).
Vertical movement should be around 1 mm. In case of too much movement, decrease both central back curves (r0fl and r0st) with -0.10 mm. In case of low riders increase both central back curves (r0fl and r0st) with +0.10 mm or in case the upper lid is pushing the lens down, increase the total diameter ØT.

In case of high riders, decrease total diameter ØT

For Toriflex TP only:

In case of instable stabilisation and/or high riders, increase the prism to 2.0 cm/m.

WARNING: the stabilisation prism induce an optical prism. This should be adjusted on both eyes.

Garantía de calidad

Estos materiales están en conformidad con la norma ISO 10993-1 que define la biocompatibilidad de los materiales.

El proceso de fabricación de SwissLens garantiza esta biocompatibilidad incluso después del proceso de fabricación, en particular sin añadir material de pulido. Este estándar es requerido por el sistema de garantía de calidad de SwissLens.

ToriFlex

ToriFlex son lentes Tóricas RGP con dos diseños diferentes. Una variación torica bi-torica y frontal-prismática dependiendo de la topografía de la córnea y la prescripción. Esto garantiza un procedimiento de ajuste fácil y rápido.
