EyeBrid Silicone fitting protocol
Fitting EyeBrid Silicone is easy! Just stick to the rules.
It is important to keep in mind that the lens should never feel incomfortable at insertion. If the patient experiences even a little bit of discomfort, remove the lens, clean it and insert again.
fit
Regular corneas
Fit with
EyeBrid Silicone 10
Fitting rule
BC = K
Power = Spectacle refraction + vertex distance
Irregular corneas
Fit with
EyeBrid Silicone
Fitting rule
BC = mean K + 0.2 (or BC trial EyeBrid/RGP lens)
Power = P trial lens + over refraction
evaluate
1. Control visual acquity
2. Do a slit lamp exam and evaluate the lens as a soft lens
The lens has to be well centered and should move as a soft lens
3. Remove the lens after several hours of wear and check corneal integrity
If no local staining ... leave the patient with the lenses

BC / P
An exemple
Keratometry: 7.45 @ 160° x 7,26
Spectacle refraction: -8.25(-1.50)160°
Prescribe
EyeBrid Silicone 10: 7.45 / -7.50

BC / P
An exemple
Keratometry: 6.80 @ 56° x 6.00
Insert EBS from trial set: 6.60 / 14.90 / -6.00
Over-refraction: -2.25 20/25
Prescribe
EyeBrid Silicone: 6.60 / -8.25
change ... in case observations are non-satisfactory
If centration and/or mobility are insatisfactory, change the skirt
Skirt too steep? Flatten the skirt by J +0.5
Skirt too flat? Steepen the skirt by J -0.5
If staining, verify the fluorescein pattern at removal and change BC
Staining in the centre? The lens is too flat. Steepen BC by -0.10 and add -0.50 d
Staining at the junction area? The lens is too steep. Flatten BC by +0.10 and add +0.50 d
Too flat
Optimal BC
Too steep
An exemple
Keratometry: 7.45 @ 160° x 7,26
Spectacle refraction: -8.25(-1.50)160°
Lens prescribed
EyeBrid Silicone 10: 7.45 / -7.50
Observations
Decentered lens
No corneal staining
Changes:
Skirt steepened by - 0.5
No change of BC
Prescribe
EyeBrid Silicone 10: 7.45 / -7.50 / - 0.5
iAdapt fitting software
iAdapt is EyeBrid's free proprietary fitting software. iAdapt guides you all the way along the fitting process, from the first lens to be ordered up to the final prescription. iAdapt calculates the parameters of the EyeBrid lenses to be ordered, as well as the modifications to be made, based on your observations.
Different comparative schemes illustrate the possible behaviours you may observe during the fitting process. Simply enter your observations and iAdapt automatically calculates the parameters of the lens to be ordered.
Easy!
