Tonometer Goldmann - X Type
Best for Slit Lamp Zeiss Style
Tonometer is an important instrument to measure the intraocular pressure.
Following the principle of Goldmann applanation tonometer, the applanation
tonometer press flat a certain area (3.06mm diameter) of patient’s cornea with
different pressure through pressure-measuring probe inlaid with a prism. Under
slit lamp microscope, and with the help of illumination of fluorescence and blue
rays, two green semi-circles whose inner parts connect each other can be seen.
Thus, numerical value of intraocuolar pressure (IOP) can be got from the reading
turn drum.
As the cornea area pressed flat by the tonometer is very small, change of
IOP caused by outer force is also very small. The eye pressure we get is nearer to
the true value of IOP as compared with Schiötz tonometer, with the mean error no
more than ±0.266Kpa. It is one of the commonly-used tonometer.
