The correct choice is the rebound tonometry technique because it measures intraocular pressure by assessing the amount of resistance felt by a small, lightweight probe as it comes into contact with the cornea. This method displaces only a minimal amount of fluid, making it a quick and efficient way to obtain pressure readings without requiring the instillation of topical anesthetics or the same degree of contact with the eye as other techniques.

Rebound tonometry is especially beneficial in settings where rapid assessments are necessary, such as in pediatric patients or those who may find it difficult to cooperate with more invasive procedures. The technique's design allows for a quick measurement that minimizes discomfort and disruption to normal ocular physiology, which is a significant advantage.

Other tonometry methods, such as Goldmann and applanation, involve more significant deformation of the corneal surface to obtain a pressure reading, thus displacing more fluid. Non-contact tonometry uses a puff of air to measure pressure but may also cause more fluid displacement than rebound tonometry.
