Abstract :

Background & Aim: Subsequent striations are related in most cases to corneal edema in users of contact lens (LC). The aim of this study is to determine the prevalence of subsequent striae cornea in patients who are users of contact lenses lotrafilcon B. Materials & Methods: A cross-sectional descriptive study with 20 female and male aged between 18 and 50 years, contact lens wearers for a minimum usage time of 6 months was studied. All the patients underwent a complete optometric examination with detailed evaluation of stroma with biomicroscope 10 to 40X magnification, to establish the presence of subsequent stretch marks (according to the criteria of N Efron) and the subjects underwent evaluation of the tear film with the Schirmer test I and BUT. With the obtained results, a descriptive statistical analysis was performed. Results: The morbidity of corneal striae was 75% of the study population, of which 60% were female, in the age group of 15-44 years, with a Schirmer 10 to 20 mm and a BUT 10 to 14 seconds. Conclusions: The occurrence of corneal striae is not directly related to material contact lenses because as seen in the results of the study, Schirmerâ??s test and BUT were above normal values.
