Epidemiology of contact lens-induced giant papillary conjunctivitis: a retrospective study

Abstract

Purpose: The purpose of the study is to determine the correlation between the incidence of giant papillary conjunctivitis induced by the use of contact lenses (CLPC) and contact lens material, replacement schedule or wearing time. The emergence of new materials and designs of contact lenses along with modifications in the replacement and wearing schedule have changed the structure of complications in users of soft contact lenses (SCLs). At present, infectious and hypoxic complications are extremely rare; on the other hand, toxic-allergic reactions that arise in users of contact lenses (CLs) have come to the fore. Material and methods. A retrospective cohort clinical study involved 1 668 users of SCL of various materials and with different replacement and wearing schedules. Patients were monitored from 2008 to 2018. Results. As a result of the study, it was found that the CLPC incidence correlate with the wearing time and replacement schedule of the SCLs.
