Optical pachymetry
WebIn summary, the actual pachymetry test, is a simple, quick and painless exam involving a small ultrasonic device which touches the cornea. It is also advantageous at gauging the health of other corneal conditions. Optical Coherence Tomography (OCT) WebPurpose: To study the effect of variables on the accuracy and reliability of the optical pachymeter built into the WaveLight EX500 excimer laser during photorefractive keratectomy (PRK). Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, USA. Design: Retrospective case series.

WebMean FT using EX500 optical pachymetry was 109 μm. The difference between FS200- programmed and EX500-measured FT was 9 μm (P,0.001). There was also a significant difference between the EX500 and OCT FT (109 μm vs 119 μm, respectively; P,0.001). Conclusion: FT values calculated using intraoperative EX500 optical pachymetry were sig- WebUltrasound pachymetry (US pachymetry) is a contact method for measuring CCT and is perhaps the most commonly used method. However, non-contact methods like scanning slit topography (Orbscan II), slit-lamp optical coherence tomography (SL-OCT), and specular microscopy are also used.
