CSO R Type Applanation Tonometer (A900)

The F900 and A900 applanation tonometers are accessories for the SL990 slit lamp to measure ocular pressure. Due to its versatile design, they can also be combined with other manufacturers equipment. The tonometers operate using the Goldmann method, meaning that it measures the pressure required for maintaining uniform applanation of the corneal surface. Precise measurement of the small flattened surface is completed using a slit lamp at 10x magnification.

Also known as the A900.

Further Information

Advantages:

  • Measurement of the patients endocular pressure is made using a slit lamp, along with other routine microscopic measurements
  • High measurement accuracy, the standard deviation amongst single measurements is approx +- 0,5mmHg
  • The value is displayed in mmHg directly on the instrument
  • Scleral rigidity consideration is not required as the small volume moved (0,56 mm3) increases intra-ocular pressure by only 2,5% (approx)
  • Measurement repetition does not reduce ocular pressure as there is no ‘massage effect’ to report
  • Simple calibration and standardization

The A900 is for those who require a permanently attached tonometer to their slit lamp. It is mounted on a pivot, on the microscope, and swung forward for examinations. A notch position ensures exact centering of the prism with the left objective. Observation of the flattened area of the corneal is made through the left eyepiece.
