Abstract

Introduction. The modern realities of the Russian market of contact lens care products dictate the search for a universal solution for one-stage cleaning, which has high disinfecting and cleansing properties for all types of contact lens materials.Purpose: investigation of the disinfecting properties of the multifunctional solution “OKVision GOLD” in relation to scleral gas-permeable lenses.Materials and methods. 20 patients (40 eyes) with keratoconus of various stages (average age 32.6 ± 2.3 years) were examined before and after wearing scleral lenses in the daytime. A clinical ophthalmological study was conducted, including a biomicroscopic assessment of the lens surfaces, as well as the anterior segment of the eye with the use of vital dyes before and after lens cleaning. In addition, smears were collected for further bacteriological examination. Evaluated: a) initial smear from the conjunctiva of the patient before putting on the contact lens; b) a smear from two surfaces of the lens after wearing it for 12 hours; c) a smear from two surfaces of the lens after 6 hours of treatment in solution. The place of analysis: G.N. Gabrichevsky research institute for epidemiology and microbiology.Results. Sowing smears from the conjunctiva before using contact correction revealed the presence of opportunistic flora. Sowing after 12 hours of wearing lenses determined the attachment of pathogenic flora. Examination of smears from lens surfaces after their 6-hour exposure in solution revealed complete inactivation of previously detected pathogenic and insignificant presence of conditionally pathogenic flora. During biomicroscopy, the condition of the eye surface remained unchanged, no deposits on the lenses were recorded. The survey of patients also revealed no negative reactions.Conclusion. The results of clinical and bacteriological studies indicate high disinfecting activity against conditionally pathogenic and conditionally pathogenic flora in the treatment of scleral lenses. This solution can be recommended for the care of all types of contact lenses, including gas-permeable ones.
