Study summary

The purpose of this research is to investigate the effects of ripasudil administered as an ophthalmic solution in patients with FED after femtosecond laser assisted cataract surgery. The secondary aim is to identity the characteristics of patients who will benefit the most with the use of ripasudil based on the test results obtained from this study.

Read the detailed description

Patients with Fuch's Corneal Endothelial Dystrophy and undergoing femtosecond laser-assisted cataract surgery will be recruited for this study. They will be randomly assigned into treatment or placebo group.

The investigators hypothesize that the ROCK inhibitor ripasudil 0.4% helps maintain corneal endothelial functional integrity and reduce cell loss after cataract surgery in patients with FED.

To test the hypothesis, the investigators plan to conduct a randomized clinical trial which aims to:

  1. Evaluate the clinical outcomes of FED eyes following FLACS with and without ripasudil 0.4%
  2. To identity which FED patients will most likely benefit from the use of ripasudil 0.4% based on pre-operative parameters
  3. To monitor for any adverse effects in patients assigned to ripasudil 0.4%

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Patients with FED who will be listed for cataract surgery as part of standard clinical practice (A cataract will be defined as clouding of the lens that interferes with normal vision).
  2. Only patients older than 50 years will be included, as cataracts develops with increasing age. No gender criteria are applied.
  3. Ability to provide , and are willing and able to sign a written Informed Consent Form prior to any study-specific procedures.
  4. Patients must be willing and able to return for scheduled follow-up examinations for up to 12 months after the surgery.

Exclusion criteria

Exclusion Criteria:

  1. Patients who are unable to give consent.
  2. An only-functioning eye in a patient who has lost visual potential in the contralateral eye.
  3. Diagnosis of eye diseases that may interfere with the aim of the study.
  4. History of ripasudil use, as well as other systemic disease such as cardiovascular or renal disease.
  5. Patients who have previous allergic reactions to the contents present in Glanatec Ophthalmic solution 0.4%
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Study arms

  • Experimental
    Treatment

    Participants in this group will be asked to instill Glanatec Ophthalmic Solution (containing Ripasadil 0.4%) 4 times a day for 1 month following cataract removal surgery.

    Drug: Ripasudil

  • Placebo comparator
    Placebo

    Participants in this group will be asked to instill saline solution 4 times a day for 1 month following cataract removal surgery.

    Other: Placebo

Interventions

  • Glanatec Ophthalmic Solution 0.4% W/V with ripasudil hydrochloride hydrate as active ingredient is currently being used by patients with ocular hypertension or open-angle glaucoma. Inhibition of Rho kinase to facilitate aqueous outflow from the conventional outflow pathway via the trabecular meshwork and Schlemm's canal has been suggested as the IOP-lowering mechanism of action by ripasudil.

    Also known as: Glanatec

What researchers measure

Primary outcomes

  1. Average endothelial cell density (ECD) is higher in participants in treatment group than participants in placebo.

    The ECD at 15 different locations of the cornea is measured with a widefield specular microscope. This assessment will be done pre-surgery, Week 1, Week 2, Week 3, 1 month, 3 months post-surgery.

    Time frame: 3 months

Secondary outcomes

  1. To monitor for conjunctival hyperemia in participants in treatment group.

    The Cornea and Contact Lens Research Unit (CCLRU) grading scale will be used as an objective assessment guideline for grading conjunctival hyperaemia. The investigators will grade the conjunctival hyperemia This assessment will be done pre-surgery, Week 1, Week 2, Week 3, 1 month, 3 months post-surgery.

    Time frame: 3 months
