Goldmann applanation tonometry after myopic photorefractive keratectomy [PDF]

Acta Ophthalmologica Scandinavica, 1998
To determine the accuracy of applanation tonometry in patients with corneas thinned by photorefractive keratectomy, and to correlate corneal changes with tonometric readings.The intraocular pressure was measured with Goldmann applanation tonometry in 87 patients who underwent photorefractive keratectomy before and 1, 6 and 12 months after treatment ...

Reutilization of disposable rebound tonometer probes: Risk or return?

Indian Journal of Ophthalmology, 2023
Purpose: An advantage of rebound tonometry (RT) is its ease of use so that it can also be operated by health care technicians. However, the cost of the disposable measuring probes is high and their reuse carries the risk of infection.

A Mathematical Model of the Goldmann Applanation Tonometry

, 2022
Abstract The aim of this study is to present mathematical formulas describing all forces involved in Goldmann applanation tonometry to calculate the measurement error of the true intraocular pressure as a function of the surface tension of the tear film, the corneal modulus of elasticity, the corneal thickness and the average apical corneal ...

Evaluation of the agreement and reliability of Transpalpebral Tonometers compared with Goldmann Applanation Tonometer – A systematic Review and Meta-Analysis Protocol

Indian Journal of Ophthalmology, 2023
In 2020, the global prevalence of glaucoma was estimated to be 76 million and it was projected to increase to 111.8 million by 2040. Accurate intraocular pressure (IOP) measurement is imperative in glaucoma management since it is the only modifiable risk
