Cataract surgery and inflammation – the role for preoperative NSAIDs (pre-CIN)

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 (pre-CIN).

Inclusion criteria

Inclusion criteria: Participants are eligible to be included in the study if all of the following criteria apply: • 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. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 5 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 200

Exclusion criteria

Exclusion criteria: Participants are excluded from the study if any of the following criteria apply: • Contraindications for use of any medication (e.g. allergy, pregnancy, breastfeeding) o Pregnancy is considered an exclusion criterion and pregnancy and contraception are commented in more detail in section 8.5 • 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.

Design outcomes

Primary

MeasureTime frame
Main Objective: Compare postoperative intraocular inflammation between different medication regimens for cataract surgery;Secondary Objective: •Compare central macular thickness and the risk of cystoid macular edema •Compare visual outcome •Compare intraocular pressure •Compare glare •Compare patient-reported outcome measures ---between the medication groups;Primary end point(s): •Laser flare ;Timepoint(s) of evaluation of this end point: Preoperatively, 1 week, 6 weeks, 6 months after surgery

Secondary

MeasureTime frame
Secondary end point(s): • Central macular thickness and macular cysts on optical coherence tomography • Corrected distance visual acuity • Intraocular pressure (applanation) • Straylight value • Comtol-scheme for ocular medication;Timepoint(s) of evaluation of this end point: Preoperatively, 1 week, 6 weeks, 6 months after surgery
