Background: Corneal pachymetry is widely used for refractive surgery and follow up in keratoconus, accurate measurement is essential for a safe surgery.
Objective: To assess intraobserver reliability of central corneal thickness (CCT) measurements using optical low-coherence reflectometry (OLCR) technology and its agreement with ultrasonic pachymeter (US).
Method: Randomized and prospective comparative evaluation of diagnostic technology.

Article Synopsis
- Corneal pachymetry is critical for safe refractive surgery, particularly for patients with keratoconus, and this study evaluates the reliability of central corneal thickness (CCT) measurements using two different devices: optical low-coherence reflectometry (OLCR) and ultrasonic pachymeter (US).
- The study involved 30 eyes from young subjects, where measurements were taken three times with both devices to analyze consistency and agreement between the two methods.
- Results showed that OLCR demonstrated high reliability and comparable measurements to US, suggesting they can be used interchangeably with slight adjustments.
