Perkins Tonometer

 

British ophthalmologist In 1965, Professor Edward "Terry" Sylvester Perkins  developed the Perkins hand-held applanation tonometer in the mid-1960s.  

Perkins designed it specifically to allow accurate IOP measurements in any position—sitting, lying down, or under anesthesia.

 

The Perkins tonometer preserved the optical and mechanical principles of Goldmann applanation tonometry while making the instrument portable.
