Contact Lenses in Therapeutic Care: A Comprehensive Review of Past Innovations, Present Applications, and Future Directions.

Contact lenses have become integral tools in the realm of ocular therapeutics, extending beyond their primary function of refractive correction to encompass a diverse array of therapeutic applications. This review explores the evolving role of contact lenses in managing various ocular conditions, highlighting their efficacy in enhancing patient outcomes. Initially developed to correct refractive errors, contact lenses now serve as effective vehicles for delivering medications directly to the ocular surface, offering targeted treatment for conditions such as dry eye syndrome and corneal ulcers. Their ability to provide sustained moisture and facilitate drug absorption makes them indispensable in promoting corneal healing and managing chronic ocular surface diseases. Specialized contact lenses designed for irregular corneas, such as those affected by keratoconus, provide both optical correction and structural support, significantly improving visual acuity and patient comfort. Additionally, orthokeratology lenses have shown promise in controlling myopia progression in children by reshaping the cornea overnight, thereby reducing reliance on corrective eyewear during waking hours. In post-surgical settings, therapeutic contact lenses aid in epithelial regeneration and minimize discomfort, accelerating recovery and improving surgical outcomes. They also play a crucial role in protecting the cornea from external irritants and promoting a stable tear film, crucial for maintaining ocular health. Looking ahead, ongoing advancements in contact lens materials and designs promise further innovation in ocular therapeutics, paving the way for personalized treatment strategies and improved patient care. As such, contact lenses continue to evolve as essential therapeutic tools, offering tailored solutions for a spectrum of ocular conditions and contributing to enhanced quality of life for patients worldwide.
