[Keratitis associated with contact lens correction in children and adolescents]

Currently, the number of contact lens users in the world is approximately 10% of the total population of developed countries. Despite the undeniable advantages of contact lenses over eyeglasses, complications are an unpleasant aspect of their use. An analysis of the literature showed that purulent-inflammatory complications have not been fully described.

To study the prevalence of keratitis associated with contact lenses, its clinical manifestations, microbial etiology, and sensitivity to antibiotics.

The study analyzes case histories of 171 patients with infectious keratitis treated at the Children's Republican Clinical Hospital of the Ministry of Health of the Republic of Tatarstan in 2016-2018.

The retrospective analysis revealed an increase in both the number of infectious keratitis and the keratitis associated with contact correction. All patients had a severe course of keratitis with the formation of gross opacity. The leading pathogens were Pseudomonas aeruginosae and Klebsiella oxytoca. The pathogens were not 100% sensitive to any one of the 7 studied antibiotics. The smallest percentage of resistant strains (12.5%) was determined for fluoroquinolones of the 2nd and 3rd generation (ciprofloxacin and levofloxacin), as well as meropenem.

Considering the number of contact lens users in the world, keratitis associated with contact lenses poses a serious problem.
