Biodegradable Contact Lenses for Targeted Ocular Drug Delivery: Recent Advances, Clinical Applications, and...

Area of Science:

• Biomaterials Science
• Ophthalmology
• Drug Delivery Systems

Background:

• Ocular drug delivery faces challenges due to anatomical barriers and tear turnover, limiting conventional topical medication efficacy.
• Chronic ocular diseases like diabetic retinopathy and macular degeneration require improved drug delivery methods.
• Drug-eluting contact lenses (DECLs) present a promising approach for sustained, localized ocular drug administration.

Purpose of the Study:

• To review recent advancements in biodegradable polymer-based drug-eluting contact lenses (DECLs) for ocular drug delivery.
• To highlight innovative design, fabrication, and drug release strategies for next-generation polymeric ocular delivery systems.
• To provide a comprehensive resource differentiating novel polymeric DECLs from existing literature.

Main Methods:

• Focus on biodegradable polymers (natural and synthetic) for DECL fabrication.
• Discussion of polymer matrix selection and drug incorporation strategies.
• Analysis of factors influencing drug release profiles from DECLs.

Main Results:

• Biodegradable polymers offer enhanced biocompatibility, tunable degradation, and programmable drug release for DECLs.
• Advances in fabrication techniques enable sophisticated DECL designs for targeted ocular therapy.
• Innovative methodologies are emerging for next-generation polymeric ocular drug delivery.

Conclusions:

• Biodegradable polymer-based DECLs represent a significant advancement in ocular drug delivery.
• These systems hold potential for improved management of chronic ocular disorders.
• Further research into polymeric DECLs promises enhanced therapeutic efficacy and patient compliance.
