Contact lens-related keratitis (CLRK) is an important ocular complication that tends to develop as a result of contact lens wear. This may potentially endanger vision. Protheragen is integrating molecular diagnostics, drug discovery, and gene therapy to treat the disease. In particular, we aim to provide advanced solutions to the pharmaceutical industry regarding its drug research and development.
Overview of Contact Lens-related Keratitis (CLRK)
Contact lens-related keratitis appears to be a multifactorial condition. The leading factor in CLRK is most microbial infections, especially those caused by Pseudomonas aeruginosa and Staphylococcus aureus, and other microbes such as Fusarium species, and Acanthamoeba protozoa. All of these pathogens can attach themselves to contact lenses and produce biofilms that are difficult to eliminate with normal antimicrobial therapeutics. The chances of acquiring CLRK increase significantly with extended wearing of lenses and the lack of sufficient hygiene practices. The symptoms can vary from mere redness and corneal discomfort to debilitating corneal ulcers and near-total loss of vision.

Diagnostics Development for Contact Lens-related Keratitis
- Bacterial Keratitis Diagnostics
The infamous keratitis related to the contact lens is bacterial keratitis. The invention of molecular diagnostics has improved the detection of bacterial pathogens. Methods like polymerase chain reaction (PCR) and next-generation sequencing (NGS) make it possible to identify bacterial DNA with high precision and accuracy. For example, within a few hours, PCR assays can target and detect Pseudomonas Aeruginosa. This allows for the swift commencement of targeted antibiotic therapeutics.
- Fungal Keratitis Diagnostics
Cultural fungi require a significant amount of time to grow which is also the reason why diagnosing fungal keratitis is a tasking process. Fortunately, with the improvements in molecular diagnostics through the use of real-time PCR and multiplex assays, detection rates have gotten better. For instance, diagnosing and identifying the specific TEF1 gene allows for the improvement of the assumption of their accuracy. As a result, antifungal therapeutics can be given and not wasted.
- Acanthamoeba Keratitis Diagnostics
This specific type of keratitis is associated with severe cases and the use of contact lenses. It is precise, using contacting lenses, myopic people. Old methods of diagnosis that are known like microscopy and culture are not enough. However, modern techniques such as PCR have proven to be very effective. The methods serve to detect not just Acanthamoeba but identify its different species which is essential in knowing the appropriate model of therapeutics.
Therapeutics Development for Contact Lens-related Keratitis
Antimicrobial Therapies
CLRK therapeutic revolves around an antimicrobial therapy regime based on the specific pathogen detected. As a rule, treatment includes the use of topical antibiotics, antifungals and anti-protozoa. Unfortunately, increasing antimicrobial resistance and biofilm infections are more complex and make improving these existing mechanisms quite challenging.
Novel Antimicrobial Agents
New classes of antimicrobial agents are currently under investigation to mitigate drug resistant pathogens. Antimicrobial peptides (AMPs), for example, can be used against biofilm infections. They are known for their multiplicative antagonistic capabilities towards bacteria, fungi, and protozoa parasites, and have lower tendency towards building resistance.
