ADEQUATE ASSESSMENT OF MORBIDITY IN CONTACT LENS CORRECTION

Abstract

Unfortunately, contact lens practitioners do not always know the methods of medical statistics in sufficient volumes. This leads to errors in the assessment of morbidity encountered in contact lens practice. In turn it can lead to erroneous conclusions. The article presents a statistically valid expression of frequency of complications, a statistically valid reliability of estimate of significant differences in this parameter between different samples. The specific examples of calculations are also given. Adequate use of medical statistics methods allows to properly evaluate the frequency of contact lens induced complications, and to use it for development of practical recommendations for professionals and patients.
