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.

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.
