1. Anterior segment OCT, ultrasound yield different thickness measurements

   PCON Supersite (Oct 9 2008) Ophthalmology Explore Article

   Anterior segment optical coherence tomography gave a lower central corneal thickness measurement than ultrasound pachymetry in a study. Because measurements from the two modalities are not interchangeable, a practice should use one modality or the other, Keith Barton, MD, FRCP, FRCS, said in a telephone interview with Ocular Surgery News. “The only purpose in publishing this was actually to highlight that when measuring central corneal thickness sequentially in clinical practice, ...

2. Anterior segment OCT useful in preop, postop evaluations of refractive surgery patients

   PCON Supersite (Jul 25 2008) Ophthalmology Explore Article

   Introduction Amar Agarwal Optical coherence tomography is a technique that uses light to create a two-dimensional cross-section image of the eye. This technique allows for imaging of either the anterior segment or the posterior segment. Decision-making for refractive surgery is aided by evaluations in either the preoperative or postoperative stages. My special guests in this column are Amin Ashrafzadeh, MD, and Roger F. Steinert, MD, who discuss the Visante anterior ... (Read Full Article)

3. Intra-observer and Inter-observer Reliability and Reproducibility of Slit-Lamp–Adapted Optical Coherence Tomography for Evaluation of Anterior Chamber Depth and Central Corneal Thickness

   PCON Supersite (Jul 22 2008) Ophthalmology Explore Article

   BACKGROUND AND OBJECTIVE To evaluate the intra-observer and inter-observer reproducibility of anterior chamber depth (ACD) and central corneal thickness (CCT) measurements taken by slit-lamp–adapted optical coherence tomography (SL-OCT) and to evaluate concordance of CCT and ACD values obtained by SL-OCT with gold standard devices. PATIENTS AND METHODS Three images of each eye were taken by two different operators using SL-OCT. ACD and CCT values obtained by each operator were determined ... (Read Full Article)

4. Central Corneal Thickness Measurements by Ultrasound, Orbscan II, and Visante OCT After LASIK for Myopia

   PCON Supersite (Apr 13 2008) Ophthalmology Explore Article

   PURPOSE To compare central corneal thickness measurements obtained with Orbscan II scanning slit topography, Visante optical coherence tomography (OCT), and ultrasound pachymetry in myopic eyes after LASIK. METHODS This retrospective study included 34 consecutive patients (68 eyes) who underwent LASIK for the correction of myopia. Six months after surgery, central corneal thickness measurements were obtained using ultrasound pachymetry, Orbscan scanning slit topography, and Visante OCT. Data were analyzed using paired ...
