Description

Biosoft 5 is the long-term solution for experienced contact lens wearers, manufactured in an innovative design, and without parameter limits, it offers comfort, the best vision and stability over time.

Adaptation

Choice Of The Definitive Lens

Biosoft 5 lenses are custom-made, so provide us with the following data :

Keratometry
Corneal diameter (HVID)
Corrected Glasses

For Multifocals we will also need:

The dominant eye
Pupillary diameter
Addition in VP

Rules For Fitting

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 taking into account the glass-eye distance

Evaluation Of Fit

After insertion, wait 5 to 10 minutes before evaluating the fit. A well-fitting lens:

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

In toric lens, check the marking of the axis which must be at 6 o’clock, and in case of rotation note the position.

Recommended actions: 
If you communicate the rotation to us, lenses under warranty will be redone taking into account this parameter

Fit for Multifocals

Multifocal lenses require an adjustment time of at least 4 days of regular wear.
The patient must be motivated and aware that there is a trade-off between wearing contact lenses and good depth of field.

FIT PROTOCOL

VL : Correction with maximum convex
VP : Minimum addition in binocular

Determination of the dominant eye:

  • The subject wears his best correction in VL, and binocularly fixes the optotype from a distance,
  •  Alternately place a +0.75 lens in front of each eye and ask the wearer when they are most uncomfortable.
  • The most uncomfortable eye is the dominant eye.

On delivery check the centering and mobility of the contact lens

Garantees

 

Biolens Lab offers a 1-month guarantee of fit for BioSoft lenses, on the condition of communicating the keratometry, or any other parameter necessary for determining the final lens.

If the parameters are defined by the prescriber, no returns can be accepted.
