Comparison of corneal pachymetry using ultrasound and Orbscan II

Journal of Cataract and Refractive Surgery, 2002
To compare Orbscan II pachymetry with ultrasonic pachymetry in eyes having corneal refractive surgery.Instituto Oftalmológico de Alicante, Alicante, Spain.In this comparative prospective study, 72 eyes (36 patients) were divided into 4 groups: Group 1, 16 eyes with haze after photorefractive keratectomy (PRK); Group 2, 12 eyes with no haze after PRK ...

Central Corneal Thickness Measurements with Optical Coherence Tomography and Ultrasound Pachymetry in Healthy Subjects and in Patients after Photorefractive Keratectomy

European Journal of Ophthalmology, 2009
PurposeTo compare central corneal thickness measurements made using two different methods, optical coherence tomography (OCT) and ultrasound pachymetry, applied both in normal eyes and in eyes on which photorefractive keratectomy (PRK) had been performed.

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

High-Frequency Ultrasound Corneal Pachymetry in the Assessment of Corneal Scars for Therapeutic Planning

Eye & Contact Lens: Science & Clinical Practice, 1994
We used high-frequency ultrasound B-scanning with digital signal processing for pachymetric analysis of corneal scars to help determine the optimal management strategy. Four patients were selected for this report. By an automated motor system, 12 consecutive, parallel ultrasound B-scans, each 2.5 to 3 mm wide at 0.25 mm intervals, were obtained from ...

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 ...

[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 ...

Validation of Confocal Microscopy Through Focusing for Corneal Sublayer Pachymetry

Cornea, 2002
To evaluate the accuracy and precision of confocal microscopy through focusing (CMTF) for corneal sublayer pachymetry.A tandem scanning confocal microscope equipped with a nonapplanating contact objective was used to perform CMTF. The accuracy of CMTF measurements was evaluated using nine custom-made calibration contact lenses (PMMA) with varying ...

[Corneal topography and pachymetry in normal eyes].

[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2003
To evaluate the corneal topography and pachymetry on normal eyes.The Orbscan corneal topography system was used to investigate corneal topography and pachymetry on 46 normal subjects.In normal eyes, island-shape was the most common type in the elevation topography of anterior corneal surface, followed by incomplete ridge, regular ridge, irregular ridge
