Fitting advices

Total diameter: = corneal diameter – 2.00 mm
Base curve:
- ASP: r0 = Kflat (rcfl)
- SMS:
  - ( rcfl – rcst) ≤ 0.30 mm -> BC = rcfl – 0.05
  - (rcfl – rcst) ≤ 0.40 mm -> rO = rcfl – 0.10
  - (rcfl – rcst) ≤ 0.50 mm -> rO = rcfl – 0.15
Flattening: ASP & SMS: eccentricity (En) = eccentricity of the cornea at 30° rounded up to the next 1/10

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 alignement 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.
