DEVELOPMENT AND STANDARDIZATION OF CALIBRATION METHODS FOR EQUIPMENT USED IN VISUAL HEALTH (KERATOMETERS, LENSOMETERS AND TONOMETERS), IMPLEMENTED IN THE HOSPITAL UNIVERSITARIO DE SAN VICENTE FUNDACIÓN. Rev. ing. biomed. [online]. 2017, vol.11, n.22, pp.21-28. ISSN 1909-9762.  https://doi.org/10.24050/19099762.n22.2017.1179.

In the field of visual health a series of equipment are used to aid in the diagnosis and treatment of the patient’s pathology. Urrently there is no standardized calibration method to ensure the measurements performed with these devices. The objective was to standardize calibration methods for some of the equipment used in the field of visual health such as keratometers, lensometers and tonometers. For the calibration of the three types of equipment included in this development, methods of direct comparison were used of the indication with the magnitude of the standards that had traceability with national and international laboratories accredited under the NTC-ISO / IEC 17025: 2005 standard. The measurements made by each of the technicians to the different types of equipment were done under repeatable conditions and using the adopted methods. Results were analyzed statistically with the simple Anova tool of Statgraphics, yielding satisfactory outcomes with a P-value above 0.05. Tests of accuracy, linearity and robustness were also performed with positive results. The adopted methods were successfully validated and later standardized under the accreditation in NTC-ISO / IEC 17025: 2005 standard.

Palabras clave : Calibration; validation; diopters; astigmatism; intraocular pressure; linearity; accuracy; robustness.
