DBR is an
Ultrasound A-Scan diagnostic procedure, which involves the
determination of axial length of the eye (the distance
between the anterior part of the eye and the posterior part
of the eye).
A-Scan is predominantly performed prior to cataract surgery
to calculate the power of the
Intra-ocular lens (IOL),
which replaces the cataractous lens. The IOL power
calculation is also based on the keratometry reading
(measures the corneal curvature). |
