Intraoperative Corneal Thickness Measurement Using Optical Coherence Pachymetry and Corneo-Gage Plus Ultrasound Pachymetry

Journal of Refractive Surgery, 2008
Purpose To compare the central corneal thickness measured by online optical coherence pachymetry (OCP) and ultrasound pachymetry in normal cornea. Methods Forty-eight right eyes of 48 consecutive patients were enrolled in this prospective study.

Orbscan Global Pachymetry: Analysis of Repeated Measures

Optometry and Vision Science, 2005
ABSTRACT: Purpose. The Orbscan II is a hybrid slit‐scanning and Placido disc corneal topographer capable mapping global pachymetry over a 10‐mm corneal diameter. In this study, the repeatability of the Orbscan global pachymetry was determined.

Pachymetry of Donor Corneas

Cornea, 2004
To examine demographic differences associated with the central corneal thickness (CCT) of donor corneas and to investigate whether these differences confirmed previous clinical studies.CCT was prospectively measured using noncontact pachymetry among 704 eye bank corneas.

Comparison of ultrasonic pachymetry with orbscan in corneal haze

Graefe's Archive for Clinical and Experimental Ophthalmology, 2007
To compare the results of ultrasonic and Orbscan pachymetry in corneal haze not related to surgery.An institutionally based, prospective, controlled clinical trial included 40 eyes of 40 consecutive patients with corneal haze not related to surgery. Fifty normal eyes were used as a control group to calculate the customized acoustic factor. Corneal haze

Diagnostic Importance of Oct Pachymetry in Keratoconus

Czech and Slovak Ophthalmology
Purpose: To evaluate the value of AS OCT pachymetry as a method capable of detecting early differences between keratoconus, latent keratoconus and corneal astigmatism based on measurements of the parameters of corneal epithelial thickness and total corneal thickness. Methods: This study analyzed 162 eyes of 89 patients examined with a Zeiss Cirrus 500

Results of Ultrasound Pachymetry and Optical Coherence Tomography Pachymetry in Patients with Congenital Glaucoma and Healthy Children

Офтальмология. Восточная Европа, 2023
Цель. Сравнить результаты измерения центральной толщины роговицы (ЦТР), полученные при помощи ультразвуковой и ОКТ-пахиметрии, у детей с врожденной глаукомой и у здоровых детей. Материалы и методы. Обследовано 57 детей (102 глаза) с первичной врожденной глаукомой и 190 здоровых детей (370 глаз). Все обследованные были разделены на 2 подгруппы.

Canine corneal thickness measured by ultrasonic pachymetry

American Journal of Veterinary Research, 1991
SUMMARY Ultrasonic pachymetry was used to measure central, superior peripheral, and temporal peripheral corneal thicknesses of 75 dogs (150 eyes) with normal corneas, anterior chambers, and intraocular pressure. Mean corneal thickness averaged over the 2 eyes, 3 locations, and 75 dogs was 562 ± 6.2 μm.

[Pachymetry in patients with glaucoma].

Ceska a slovenska oftalmologie : casopis Ceske oftalmologicke spolecnosti a Slovenske oftalmologicke spolecnosti, 1999
Central corneal thickness (CCT) was measured in 328 eyes of 167 patients (50 men and 117 women, an average age was 62 years). CCT was determinated by ultrasonic pachymeter NIDEC, design UP-1000, at Eye Department of 3rd Medical Faculty of Prague.The mean CCT at glaucoma patients was 561 microns, in margins 490-650 microns. CCT for right eyes were 0.567

Corneal thickness measured by ultrasonic pachymetry in cats

American Journal of Veterinary Research, 1993
SUMMARY Ultrasonic pachymetry was used to measure central superior peripheral, and temporal peripheral corneal thickness of 35 cats (70 eyes) with normal corneas, anterior chambers, and intraocular pressures. Mean central corneal thickness for both eyes in 3 locations for 35 cats was 578 ± 64 µm.

Accuracy of Orbscan optical pachymetry in corneas with haze

Journal of Cataract and Refractive Surgery, 2002
To compare corneal thickness measurements with the Orbscan instrument (Orbtek, Inc.) and an ultrasonic pachymeter (Alcon Surgical) in corneas with haze.Department of Ophthalmology and Otolaryngology, University of Bari, Bari, Italy.Six eyes of 6 patients having phototherapeutic keratectomy for treatment of grade 2+ haze were assessed preoperatively and
