The non-contact tonometry process entails directing a quick burst of air on the cornea to measure intraocular strain. This measurement helps assess the fluid strain inside the attention, which is a crucial indicator of ocular well being. For instance, elevated strain is usually a danger issue for sure eye situations.

This methodology is efficacious in glaucoma screening on account of its velocity and non-invasive nature. Its historic adoption displays a transfer in the direction of affected person consolation and effectivity in routine eye examinations.

This measurement approach, also called non-contact tonometry, makes use of a speedy burst of air to applanate, or flatten, the cornea. The instrument measures the intraocular strain primarily based on the drive required to realize this corneal flattening. For instance, if the air puff ends in minimal corneal deformation, it signifies the next resistance, suggesting elevated strain inside the eye.

This system is efficacious for glaucoma screening as a result of elevated intraocular strain is a major danger issue for the illness. Its benefits embody velocity and the elimination of direct contact with the attention, which minimizes the chance of an infection and sometimes removes the necessity for anesthetic drops. The underlying expertise has been in use for a number of many years, always evolving to enhance accuracy and affected person consolation.
