Contact lenses and corneal shields.

Area of Science:

• Ophthalmology
• Corneal Science
• Ophthalmic Drug Delivery

Background:

• Contact lenses are prevalent globally for cosmetic and therapeutic purposes.
• Proper fitting and handling are crucial for safe contact lens use.
• Potential complications include tear film disturbances, corneal alterations, and microbial keratitis.

Purpose of the Study:

• To review the indications for contact lens wear.
• To discuss the risks and complications associated with contact lenses.
• To explore the emerging role of collagen bandage lenses in corneal defect treatment and drug delivery.

Main Methods:

• Literature review of contact lens indications, complications, and therapeutic applications.
• Analysis of studies on tear film and corneal morphologic changes.
• Examination of research on microbial keratitis and collagen bandage lens usage.

Main Results:

• Contact lenses serve as effective cosmetic and therapeutic tools when used correctly.
• Adverse effects can include significant ocular surface changes and infections.
• Collagen bandage lenses show promise in treating corneal epithelial defects and delivering drugs for severe corneal infections.

Conclusions:

• Contact lens wear necessitates careful management to mitigate risks.
• Collagen bandage lenses represent an advancing technology for ocular surface disease and infection treatment.
• Further research into contact lens-related complications and advanced lens applications is warranted.
