2. The Bausch and Lomb Keratometer is a one position Keratometer that gives readings in dioptric form.
Most widely used instrument for
measuring the curvature of the anterior
corneal surface.
Uses of BAUSCH & LOMB CAT 71.21.35 KERATOMETER
• Contact lens practice - base curve selection,
Overkeratometry
• Assess extent and axis of astigmatism
• Monitoring distortion of corneal surface:
keratoconus, oedema, C/L wear, surgery
• Determine whether ametropia is of refractive or
axial etiology
• Provides quantitative description of central
corneal curvature
• Calculate IOL power
Gives readings in dioptric
form.
• Object size is fixed.
• Image doubling size is the
variable.
• Can measure both principal
meridians without having to
reposition the instrument.
• Principle meridians are
assumed to be at right angles
to each other.
Quick to use.
• Assumes meridians are at 90 degrees.
Shorter working distances
•Vertical and horizontal mires imaged
at the same time.
