Ultrasonic pachymeter

Ultrasound technology can help probe the human eye without causing damage to this delicate organ, and so its use in ophthalmology is constantly expanding. In 1eyes of both controls and patients with open-angle glaucoma (normal intraocular pressure) attending Ibn Al Haitham Teaching Eye Hospital, CCT was measured by oculus pentacam and then by ultrasound pachymeter at the same morning by the same technicians. Central corneal thickness (CCT) can be measured by using contact and non-contact methods.

However, non-contact methods like scanning slit topography . Measurement of central corneal thickness by ultrasonic pachymeter and oculus pentacam in patients with well-controlled glaucoma: hospital-based comparative study.

Corneal pachymetry is the process of measuring the thickness of the cornea.

It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of . Takagi PUltrasonic Pachymeter. Sonomed 300P ultrasonic pachymeter including straight probe without printer. Features Technical Accessories . Methods: The current study was performed at Labbafinejad Medical Center (LMC ), Tehran, Iran.

Three hundred eyes from 1healthy individuals referred for keratorefractive surgery were assessed first by Orbscan II and then by ultrasound pachymetry , and CCT values were recorded and compared. To compare the RTVue spectral optical coherence tomography (SD-OCT), Sirius Scheimpflug-Placido topographer, Lenstar optical low coherence reflectometry (OLCR) and ultrasound pachymetry (USP) devices in terms of their agreement and repeatability of measuring central corneal thickness . Ultrasound (US) pachymetry , although considered to be the gold standard metho has limitations and drawbacks such as operator-dependency and concerns regarding contact methods which has incited the introduction of non- contact objective methods. Consequently, evaluation of inter- pachymeter agreement has .

Corneal thickness measurements with contact and noncontact specular microscopic and ultrasonic pachymetry. Comparison of corneal thickness measurement with the Pentacam, the PARKand an ultrasonic pachymeter. Hashemi H(1), Jafarzadehpur E, Mehravaran S, Rezvan F, Bigdeli S. Ultrasound pachymetry and Artemis-measurements of central corneal thickness were highly correlated. The 11-micron mean difference between the pachymeter and Artemis measurements may be attributed to decentration, oblique incidence of the probe to the cornea or possibly the effect of topical anesthetic when using . To assess the reproducibility . Ultrasonic pachymetry has largely replaced optical pachymetry, because ultrasound units are easy to use and accurate.
