Clinical Trial Summary

The pre-CIN trial is a randomized clinical three-arm trial comparing inflammation and cystoid macular edema for the medication regimens preoperative and postoperative topical NSAIDs to only postoperative topical NSAIDs to postoperative topical NSAIDs and steroids in patients undergoing cataract surgery.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 500
• Est. completion date: December 2023
• Est. primary completion date: August 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Patients must be 18 years and older at the time of the signing of the informed consent. There is no upper age limit.

• Scheduled for standard phacoemulsification cataract surgery (group 1 - 3)

• Scheduled for combined phacoemulsification cataract surgery and MIGS stent (group 4)

• Ability to cooperate fairly well during the examinations

• Willing to participate in the study and capable of giving informed consent, which includes compliance with the requirements and restrictions in the informed consent form (ICF) and in this protocol.

Exclusion Criteria:

• Contraindications for use of any medication (as listed in the approved SPC, e.g. allergy, pregnancy, breastfeeding)

• Pregnancy

• Diabetes

• Mature cataract

• Active or chronic uveitis with recommendation for steroid treatment

• Previous trabeculectomy

• Other ophthalmological conditions and/or complicating factors requiring steroid treatment (group 1 - 3)

• Cornea pathology requiring specific medication regimens (e.g. herpes pathology, previous corneal transplantation)

Patients with complications or other complicating factors during surgery that causes the surgeon to demand both NSAIDs and steroid treatment will be excluded from the main analysis. These patients will be followed postoperatively as part of the study and included in additional analyses (for example as part of an intention to treat analysis).

For patients scheduled for cataract surgery in both eyes, only the first operated eye will be included, however, both eyes will be examined.
