Resumen
Contact lenses are an alternative method to correct ocular ametropia, they are made of plastic materials which must maintain the stability of the tear film and provide comfort through their physical properties. However, cases of discomfort due to LCB are reported, added to this there is a lack of information and standardization in the scientific and clinical field, for which the objective of this study was to identify the influence of the properties of the materials used in the manufacture of soft contact lenses on discomfort. To carry out the study, information was collected using related keywords in the Decs and MeSH, which were used in databases through search equations. Subsequently, complete articles were selected based on observational, experimental and systematic review investigations. of the literature, excluding publications in which their quality percentage is less than 60% and their year of publication prior to 2013. Finally, a search for scientific articles was carried out on the types of materials for the manufacture of soft contact lenses and their influence on discomfort, which showed that the best material for manufacturing is silicone hydrogels, since these provide good optical quality. , wettability, and initial comfort, although it should not be ruled out that they can cause discomfort in the user at the end of the day or when the time of use is exceeded. In addition, it was evidenced that the discomfort felt by soft contact lens wearers occurs with the use of conventional hydrogel material caused by low oxygen transmissibility.
