255:. Using this technology the user can capture an ultra high definition echogram of cornea, think of it as a corneal A-scan. Pachymetry using the corneal waveform allows the user to more accurately measure the corneal thickness, have the ability to check the reliability of the measurements that were obtained, have the ability to superimpose corneal waveform to monitor the change of patients cornea over time, and ability to measure structures within the cornea such as micro bubbles created in the cornea during femto-second laser flap cut.

218:. Using this technology the user can capture an ultra-high definition echogram of the cornea, somewhat like a corneal A-scan. Pachymetry using the corneal waveform process allows the user to more accurately measure the corneal thickness, verify the reliability of the measurements that were obtained, superimpose corneal waveforms to monitor changes in a patient's cornea over time, and measure structures within the cornea such as micro bubbles created during femto-second laser flap cuts.

242:. As a result of this study and others that followed, corneal pachymetry is now widely used by both glaucoma researchers and glaucoma specialists to better diagnose and detect early cases. Newer generation pachymeters have the ability to adjust the intraocular pressure that is measured according to the corneal thickness.

by placing a pair of incisions of a particular depth and arc length at a steep axis of corneal astigmatism. By using the corneal pachymetry the surgeon will reduce the chances of perforation of the eye and improves surgical outcome. Newer generations of pachymeters will help surgeons by providing

Modern devices use ultrasound technology, while earlier models were based on optical principles. The ultrasonic

Scheimpflug camera (such as SIRIUS or PENTACAM), or a Dual Scheimpflug camera (such as GALILEI), or Optical Coherence Tomography (OCT, such as Visante) and online Optical Coherence
238:. In 2002, the five-year report of the Ocular Hypertension Study (OHTS) was released. The study reported that corneal thickness as measured by corneal pachymetry was an accurate predictor of glaucoma development when combined with standard measurements of
