Because of the continued popularity of contact lenses in the United States, ocular inflammatory diseases are being encountered with increasing frequency by both ophthalmologists and primary care physicians. Distinction between minor noninfectious inflammation and serious, sight-threatening infection is crucial to the proper management of these patients. Symptoms of infectious keratitis are pain and loss of vision. Signs include infiltration or loss of clarity of the cornea, eyelid swelling, and purulent discharge. If an infectious process is suspected, the patient should be referred to an ophthalmologist immediately. If this is not possible, the contact lens should be removed and a culture performed, if possible. Aminoglycoside antibiotic drops should be applied frequently until ophthalmologic consultation is obtained. Patients should be reminded of the need for strict adherence to disinfection techniques and avoidance of homemade saline preparations. They should also be told to discontinue use of contact lenses at the first sign of ocular irritation or inflammation and to report to their physician if inflammation persists.

This study aims to build an optimal drug delivery system by manufacturing and evaluating a hydrogel contact lens using Tretinoin (ATRA) and protein nanoparticles to improve the drug delivery system as an ophthalmic medical contact lens. To evaluate the optical and physical properties of the manufactured lens, the spectral transmittance, refractive index, water content, contact angle, AFM, tensile strength, drug delivery, and antibacterial properties were analyzed. The contact lens was manufactured to contain ATRA and bovine serum albumin (BSA) in different ways, and the results confirmed that A, B, and C each had different physical properties.

Ocular cystinosis is a disease in which accumulated cystine crystals cause damage to the eyes, necessitating timely treatment and ongoing monitoring of cystine levels. The current treatment involves frequent administration of cysteamine eye drops, which suffer from low bioavailability and can lead to drug toxicity, making it essential to prescribe an appropriate dosage based on the patient's condition. Additionally, cystine crystal levels are typically assessed subjectively via slit-lamp examination, requiring frequent clinical visits and causing discomfort for the patient.
