SOCT User Manual Version 10.0 rev. A
IOL User The user has to determine and enter the refraction index of the patient’s IOL.
For the vitreous humor you can choose between:
Natural: The vitreous body has never been operated or treated such as to alter its
composition.
Silicon Oil The vitreous body has been filled, even only partly, with silicon oil.
The measured axial eye length depends on the measuring mode selected. Depending on the
measuring mode selected, SOCT corrects the measurement with a constant defined as follows.
SOCT takes into consideration two conditions of the eye that can alter the measurement of
axial length:
• Vitreous body filled of silicone oil
• Implant of IOL intra ocular lens
The difference of the measurement is caused by a different group refraction index considered
in the formula. According to bibliographic data, the calculations have been performed to assess
the amount of correction that must be applied to correct the measurement in these special
cases.
