Contact Lens-Related Corneal Infections

Area of Science:

• Ophthalmology
• Microbiology

Background:

• Microbial keratitis (MK) is a significant cause of vision impairment.
• Contact lens wear is a primary risk factor for developing MK.

Purpose of the Study:

• To provide an updated review of contact lens-associated microbial keratitis (CL-MK).
• To discuss prevalence, risk factors, causative organisms, clinical presentation, and treatment strategies for CL-MK.

Main Methods:

• Literature review of current research on contact lens-associated microbial keratitis.
• Analysis of prevalence, risk factors, and etiological agents.
• Summary of clinical manifestations and therapeutic approaches.

Main Results:

• Bacterial pathogens are the most common cause of CL-MK, followed by fungi and protozoa.
• Overnight wear, poor hygiene, and specific contact lens types increase MK risk.
• Symptoms include pain, redness, and vision loss, varying with the causative organism.

Conclusions:

• Preventive measures, including strict hygiene and avoiding overnight wear, are essential.
• Prompt diagnosis and appropriate antimicrobial therapy (antibiotic, antifungal, antiprotozoal) are critical.
• Surgical intervention is reserved for severe, non-responsive cases of CL-MK.
