Fungal-contaminated soft contact lenses

Area of Science:

• Ophthalmology
• Mycology
• Biomaterials Science

Background:

• Soft contact lenses can become contaminated with fungi, with the microorganisms found in a highly reproductive state within the lens matrix.
• Fungal contamination of contact lenses presents a potential hazard to the cornea, necessitating investigation into the associated risks.

Purpose of the Study:

• To evaluate the potential hazard of fungal-contaminated soft contact lenses to the cornea.
• To assess the clinical implications of fungal presence within soft contact lens materials.

Main Methods:

• Fungal-contaminated soft contact lenses were placed on abraded corneas of ten rabbits.
• Sterile lenses were used as a control on the opposite cornea of each rabbit.
• Corneal health and signs of infection were monitored post-application.

Main Results:

• No cases of fungal keratitis were documented in the experimental group.
• Persistent corneal epithelial disruption was observed in seven out of ten rabbits exposed to contaminated lenses.
• Fungi within the lens matrix were observed in a highly reproductive state.

Conclusions:

• Fungal-contaminated soft contact lenses may pose a significant risk to patients, evidenced by corneal epithelial disruption.
• The highly reproductive state of fungi within lenses underscores the potential for adverse ocular events.
• Prompt replacement of contaminated lenses and enhanced patient education on proper lens hygiene are recommended.
