Corneal densitometry and its correlation with age, pachymetry, corneal curvature, and refraction

International Ophthalmology, 2016
To determine normative corneal densitometry values in relation to age, sex, refractive error, corneal thickness, and keratometry, measured using the Oculus Pentacam system.Three hundred and thirty-eight healthy subjects (185 men; 153 women) with no corneal disease underwent an exhaustive ocular examination.

Corneal pachymetry in normal and keratoconic eyes

Journal of Cataract and Refractive Surgery, 2004
To compare corneal thickness measurements using Orbscan II (OII) and ultrasonic (US) pachymetry in normal and in keratoconic eyes.Eye Department, Heartlands and Solihull NHS Trust, Birmingham, United Kingdom.Central corneal thickness (CCT) was measured by means of OII and US pachymetry in 1 eye of 72 normal subjects and 36 keratoconus patients.

Correction Factor in Orbscan II in the Assessment of Corneal Pachymetry

Cornea, 2006
Comparison of corneal pachymetry assessment with ultrasound and Orbscan II using acoustic factor and subtraction methods.Ultrasound and Orbscan pachymetry for all patients with LASIK performed between July 2002 and May 2003 were retrospectively analyzed. Comparison between the 2 preoperative measurements was analyzed.Using a custom acoustic factor of 0.

Impact of Scleral Lens on Corneal Curvature and Pachymetry in Keratoconic Eyes

Cornea, 2021
Purpose: The aim of this study was to evaluate the influence of scleral lens on corneal curvature and corneal thickness in keratoconic patients. Methods: Scheimpflug imaging was captured before lens insertion, immediately after removal at 6 hours, and, again, the next day morning ...

Intraoperative corneal pachymetry in eyes having radial keratotomy

Journal of Cataract and Refractive Surgery, 1995
We prospectively studied 45 eyes that had radial keratotomy for correction of myopia to determine whether significant changes in corneal thickness occurred during the surgical procedure and which paracentral corneal region was the thinnest consistently. We used a standard bidirectional technique with a diamond knife.

Corneal Hysteresis, Resistance Factor, Topography, and Pachymetry After Corneal Lamellar Flap

Journal of Refractive Surgery, 2007
Purpose: To measure prospectively the early changes in corneal hysteresis, topography, and pachymetry after the creation of a stromal flap cut without laser photoablation. Methods: A 37-year-old man was referred for a bioptic procedure

[Corneal pachymetry and intraocular pressure].

Klinische Monatsblatter fur Augenheilkunde, 2005
Just recently studies on glaucoma have emphasised the significance of intraocular pressure in the diagnosis of glaucoma and the importance of intraocular pressure reduction in the management of glaucoma. Central corneal thickness appears to play an important role in the exact measurement of intraocular pressure and in the diagnostic assessment of ...
