Recent advances in nanotechnology for the treatment of fungal keratitis

Area of Science:

• Ophthalmology
• Pharmacology
• Nanotechnology

Background:

• Fungal keratitis (FK) is a severe ocular infection with limited treatment options.
• Current topical antifungal eye drops suffer from poor corneal penetration, low bioavailability, and necessitate frequent dosing, leading to poor patient compliance.
• Nanocarriers present a promising strategy to overcome these limitations in ocular drug delivery.

Purpose of the Study:

• To review the mechanisms of action of antifungal drugs for FK.
• To discuss the theoretical basis and recent advances in FK clinical treatment.
• To summarize research on nanocarriers for ocular antifungal drug delivery, evaluating their efficacy and safety.

Main Methods:

• Literature review of antifungal drug mechanisms.
• Analysis of theoretical approaches to FK treatment.
• Synthesis of research findings on nanocarrier-based ocular drug delivery systems for FK.

Main Results:

• Nanocarriers can improve drug penetration and bioavailability in the cornea.
• Sustained and controlled release from nanocarriers enhances drug duration and efficacy.
• Nanocarriers protect antifungal drugs from ocular degradation and clearance mechanisms.

Conclusions:

• Nanocarriers show significant potential for improving the treatment of fungal keratitis.
• Optimized nanocarrier formulations can enhance drug delivery, efficacy, and patient compliance.
• Further research into nanocarrier safety and efficacy is crucial for clinical translation in FK therapy.
