[Risks and complications of contact lens use]

Area of Science:

• Ophthalmology
• Biomaterials Science

Background:

• Contact lenses, both hard and soft, are widely used for vision correction.
• A subset of contact lens wearers experience ocular complications.
• These complications can stem from mechanical, toxic, metabolic, or allergic reactions.

Purpose of the Study:

• To highlight the potential complications associated with contact lens wear.
• To identify the causes of these ocular complications.
• To emphasize the importance of proper contact lens care and professional monitoring.

Main Methods:

• Review of existing literature on contact lens-related ocular complications.
• Analysis of causative factors including lens material, cleaning solutions, and wear duration.
• Emphasis on patient education and ophthalmological follow-up.

Main Results:

• Ocular complications in contact lens wearers are multifactorial.
• Sensitization of the anterior eye by cleaning/disinfecting agents or lens material is a primary cause.
• Improper lens hygiene and prolonged wear increase the risk of eye injury.

Conclusions:

• Thorough patient instruction on contact lens handling and hygiene is essential.
• Regular visits to an ophthalmologist are critical for early detection and prevention of complications.
• Adherence to proper care protocols can significantly reduce the incidence of adverse events in contact lens wearers.
