Description

Hand-made tints and custom-made lenses by Biolens Lab, with a wide range of tints and parameters to restore a natural look to your eye.

Choice Of The Definitive Lens

IriSoft lenses are custom-made, so provide us with the following data :

Keratometry
Corneal diameter (HVID)
Glasses correction

For Multifocals we will also need :

The dominant eye
Pupillary diameter
The addition in VP

Fitting Rules

You can choose the parameters of the lenses (without guarantee of fit), by applying the following rules :

LC diameter = Corneal diameter (HIVD) + 2 mm
Radius: Depending on the total diameter:
13.50: R0=Km+0.4         14.00: R0=Km+0.6
14.50: R0=Km+0.8         15.00: R0=Km+1.0
Convert glasses strength into contact lenses by taking into account the glass-eye distance

Evaluation of Fit

After insertion, wait for 5 to 10 minutes before evaluating fit.

A good-fitting lens:

Shows 0.5 to 1 mm blinking movement
On “push up” the lens refocuses quickly
Its edge is 1 to 1.5 mm from the limbus
Is comfortable

Poor Fit

Blurred vision after blinking
Excess mobility
Axis rotation with toric lenses
Induced astigmatism with additional refraction
Discomfort

Recommended Actions:
Increase the diameter by at least 0.50 or tighten R0 by at least 0.2 mm

Tight Fit

Clear vision after blinking
Reduced mobility
Axis rotation for toric lenses

Recommended Actions:
Decrease the diameter by at least 0.50 or flatten R0 by at least 0.2 mm

Cyl Axis Rotation

En lentille torique, vérifiez le marquage de l’axe qui doit être à 6 heures, en cas de rotation notez la position.

Actions  recommandées: 
Nous communiquer la rotation, les lentilles sous garanties seront refaites en tenant compte de ce paramètre
