The Intra and Inter-Examiner Repeatability of Corneal Parameters Obtained by GALILEIM in Normal Subjects

Purpose: To verify the intra-examiner and inter-examiner repeatability of corneal parameters obtained by GALILEITM. Methods: Corneal parameters were measured by GALILEI in 44 eyes of 28 healthy subjects. One examiner took the measurements twice and intra-examiner repeatability was evaluated. Another examiner measured the corneal parameters once again and interexaminer repeatability was evaluated. Results: Intra-examiner and inter-examiner repeatability were high for corneal parameters including average SimK, flat SimK, steep SimK, average posterior corneal keratometry, flat posterior corneal keratometry, steep posterior corneal keratometry, central corneal thickness, total corneal volume, and average pupil diameter but low for limbus-to-limbus diameter (nasal-temporal and superior-inferior). Conclusions: Anterior and posterior corneal parameters of GALILEI showed good intra-examiner and inter-examiner repeatability. However, limbus-to-limbus diameter showed poor intra-examiner and inter-examiner repeatability. GALILEI can be useful in clinical applications with special consideration when measuring the limbus-to-limbus diameter. J Korean Ophthalmol Soc 2009;50(11):1611-1616
