Care Solutions

Without Hydra-PEG treatment

Use RGP solutions (AcuaCare StoreFlex) for storing and Alcohol cleaner (AcuaCare AllCleaner) for daily cleaning. Not use abrasive cleaners.

Alternatively, the one step-T Peroxide can be used too.

With Hydra-PEG treatment

Please only use the recommended cleaning solutions. The one step-T can be used with Hydra-PEG

See List and more information about Hydra-PEG

Fitting advice

Choosing the First Trial Lens

The ScleraFlex have to be fitted empirically as keratometry and topography do not give a good indication of sagittal depth. However, the first trial lens can be chosen based on the eye condition to be fitted. Then choose number 2 of this group.


Lenses must always be inserted full to the brim with saline. Fluorescein must be added to the bowl of the lens prior to insertion as it will not get behind the lens after insertion.
The patient should be bent forward with their nose pointing towards the floor and their chin tucked in. The lens can either be supported on a tripod of three fingers or on a DMV inserter.

Ideal Fit

After 1 hour of testing, the tear film thickness should be approx. 200 – 250 micrometers (corresponds to approx. 1/2 to 1/3 thickness of the cornea).
After a whole day, the tear film thickness in the center should be reduced to approx. 100 – 125 micrometers (equivalent to approx. 1/4 of the cornea thickness).
A good fit will :

  • Low vaulting of the cornea
  • No scleral impingement
  • Limbal clearance


Shallow / Flat Fit

Sagittal depth of the lens is less than the sagittal depth of the eye. A flat fit will show:

  • Edge lift
  • Central bearing
  • Discomfort

Action: Remove the lens and insert a lens with a higher sag (a deeper lens)

Deep / Steep Fit

Sagittal depth of the lens exceeds the sagittal depth of the eye.

A deep or steep fit will show:

  • Excessive central NaFL pooling
  • Central bubble
  • Scleral impingement

Action: Remove the lens and insert a lens with a lower sag (a more shallow lens)

Assessing The Edges

To assess the edge of the lens, push the inferior sclera just below the edge of the lens. If the lens flares away very easily, it is flat. If it takes a significant push to get any flaring away of the lens, the edge is tight or the lens is too deep.


  • If edge impingement or scleral blanching, order the lens with a flattening (+) 
  • If buble in the preiphery or edge stand, order the lens with a flattening (-)

The test lens will show support at the peripheral cornea due to corneal shape. A lens with an inverse geometry must be chosen. It will be determined by the choice of a fitting sphere. First, intentionally choose a fitting sphere of +5.00. If this is not sufficient, increase its value to +10.00 diopters. The fitting sphere will eliminate peripheral approximation and render the fluorescent image similar to that of an adaptation on a classic cornea.
WARNING: this change will change the power of the lens, but the refractive power will remain the same.

Marks and stabilisation

The scleral lenses are available with the following toric variants:

  • Back Periphery Toric (ASY): 2 marker points in the flat meridian
  • Front toric: 2 lines on the refraction axis
  • Combination of ASY & Front Toric: 2 marker points on the flat meridian and one point at 90° to insert the contact lens correctly upwards
