Impact of gender‐specific differences in corneal elasticity upon IOP measurements using vibration tonometry

Purpose Vibration Tonometry enables precise non‐contact tonometry independently of CCT and post LASIK using induced corneal vibrations response to calculate IOP using different algorithms for men and women. This corneal vibrations response reflects different tissue elasticity between men and women....

Description
Summary:Purpose Vibration Tonometry enables precise non‐contact tonometry independently of CCT and post LASIK using induced corneal vibrations response to calculate IOP using different algorithms for men and women. This corneal vibrations response reflects different tissue elasticity between men and women. We calculate IOP error using gender‐inverted algorithms: female algorithm for men and vice versa Methods Vibration Tonometry IOP data from clinical trials in 324 subjects in 3 IOP groups and in 3 age groups. 1,040 and 1,031 measurements were used respectively in women and in men Results Using men algorithm for women mean IOP difference was −0.376 mm Hg; 0.07 mmHg; 1.937 mmHg respectively in the 23 mm Hg group significantly different p
