In this study, two treatments typically used for dry eye disease will be tried for contact lens users to see if their symptoms when they use their contact lenses get better. Cyclosporine is a drop that is used for long-term management of the inflammation and Intense pulsed light (IPL) is a treatment done in a clinic to improve the health of the eyelid glands. The main question in this study is: Does the combined treatment of cyclosporine and IPL improve the symptoms and the dry eye signs of contact lens wearers? All the participants will receive the cyclosporine drops for 4 months twice a day. The research team will split the group of participants in two, half receiving the real IPL treatment and half receiving a sham IPL treatment during the last two months of the study. This will allow to compare the two groups to see how IPL helped. The dry eye tests will be done at the start of the study, after two months and after 4 months. The tests will include a dry eye symptoms questionnaire, measures on the tears, the structures of the front of the eye and the eyelids.

This randomized clinical trial will assess corneal astigmatism and visual outcomes in participants who have undergone corneal transplantation for keratoconus with ex vivo cross-linked donor corneal tissue versus participants who have undergone corneal transplantation for keratoconus with non-cross-linked donor corneas. Crosslinking is a procedure that stabilizes the biomechanical properties of the cornea; as a result, the cornea stiffens. It has been shown that this procedure stabilizes the cornea of patients with keratoconus or corneal ectasias. The FDA currently approves crosslinking for patients with progressive keratoconus and corneal ectasia following refractive surgery. Ex vivo crosslinking of donor corneal tissue for patients with keratoconus undergoing PK or DALK could stabilize the cornea and reduce the risk of high astigmatism and improve vision in patient with keratoconus.

This trial tests levocarnitine, a supplement that helps transport carnitine into cells, in adults with Sjogren's syndrome who have dry eyes. Sjogren's syndrome causes dryness in the eyes and mouth. Levocarnitine may help by increasing carnitine levels in tears, potentially reducing eye dryness and improving comfort. Levocarnitine is a molecule required in mammalian energy metabolism, facilitating the transport of long-chain fatty acids across the mitochondrial membrane for energy production.

Corneal collagen crosslinking has been demonstrated as an effective method of reducing progression of both keratoconus and post-refractive corneal ectasia, as well as decreasing the steepness of the cornea in these pathologies. Performing an accelerated CXL procedure with pulsed UVA light may increase the oxygenation of the cornea, which may improve the crosslinking efficacy.

Keratoconus is a non-inflammatory, progressive disease in which corneal irregularity increases. As the condition develops, more advanced forms of optical correction are needed to improve vision for patients. Until recently, small diameter corneal gas permeable lenses were considered the primary mode of correction for patients with keratoconus. Now, however, practitioners have multiple options for reducing the optical aberrations caused by keratoconus, including scleral lenses. As of yet, no single option for optical correction has been identified as the preferred mode of correction in terms of overall patient satisfaction with vision, comfort, and ease of use. The order in which various forms of optical correction would be most logically introduced has yet to be determined. This is a study comparing small diameter corneal gas permeable and large diameter scleral lenses in individuals with keratoconus. This study will prospectively compare visual satisfaction and ease of use between corneal gas permeable and scleral lenses for patients with mild to moderate keratoconus.

Corneal collagen crosslinking (CXL) has been demonstrated as an effective method of reducing progression of both keratoconus and corneal ectasia after surgery, as well as possibly decreasing the steepness of the cornea in these pathologies. Transepithelial crosslinking in which the epithelium is not removed has been proposed to offer a number of advantages over traditional crosslinking including an increased safety profile by reducing the risk for infection and scarring, faster visual recovery and improved patient comfort in the early postoperative healing period.

Corneal collagen crosslinking (CXL) has been proposed as an effective method of reducing progression of both keratoconus and corneal ectasia after surgery, as well as possibly decreasing the steepness of the cornea in these pathologies. During previous studies of the CXL procedure, the surface epithelial cells have been removed. Transepithelial crosslinking in which the epithelium is not removed has been proposed to offer a number of advantages over traditional crosslinking including an increased safety profile by reducing the risk for infection as no epithelial barrier will be broken, faster visual recovery and improved patient comfort in the early postoperative healing period.

Frequently Asked Questions

How much do Keratoconus clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Keratoconus clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Keratoconus trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Keratoconus is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Keratoconus medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Keratoconus clinical trials ?

Most recently, we added Plasma Tear Drops for Dry Eye Syndrome, TTAX03 for Dry Eye Syndrome and AR-15512 for Dry Eye Syndrome to the Power online platform.
