- Brief Summary
Cystoid macular edema (CME) is a major cause of suboptimal postoperative visual acuity after cataract surgery. Topical steroidal and nonsteroidal anti-inflammatory drugs (NSAIDs) are used to prevent CME. However, noncompliance with eye drops may compromise the effectiveness of treatment. Dropless periocular drug delivery during cataract surgery may improve the outcomes and cost-effectiveness of cataract surgery, and may alleviate the burden on homecare organizations.
- Detailed Description
In a recent European multicentre study (PREvention of Macular EDema after cataract surgery; PREMED), it was demonstrated that the combination of topical corticosteroids and NSAIDs results in the lowest risk of developing CME after cataract surgery. However, noncompliance with eye drops may compromise the effectiveness of treatment. Noncompliance is often unintentional and related to forgetfulness or incorrect instillation, particularly in the elderly cataract surgery population.
The objective of this study is to evaluate the effectiveness of different treatments to prevent CME after cataract surgery, using either topical drugs (control group) or intra-/periocular injections (intervention groups).
The hypothesis of this study is that intra-/periocular anti-inflammatory drug delivery during cataract surgery is effective in preventing CME, with better health-related quality of life and improved cost-effectiveness compared to standard topical drug delivery.
The primary outcome measure is the change in central subfield mean macular thickness (CSMT) at 6 weeks postoperatively as compared to baseline. Secondary outcome measures are the incidence of CME; the incidence of clinically significant macular edema (CSME); mean corrected distance visual acuity (CDVA); para- and perifoveal thickness and total macular volume (TMV); intraocular pressure (IOP); anterior chamber inflammation; vision-related quality of life; and cost-effectiveness.
The design of this study is a European randomised controlled multicenter trial. The study population will consist of 808 patients aged 21 years or older who require cataract surgery in at least one eye. Patients with a foreseen increased risk of developing CME or ophthalmic disorders other than cataract will be excluded. Follow-up duration is 12 weeks. The study will be conducted over a period of 36 months.

A 4ml vial of Omidria (ketorolac concentration 2.88mg/ml) is added to 500ml of the irrigation solution used during cataract surgery, resulting in a ketorolac concentration of 0.023mg/ml. At the end of the surgery, the anterior chamber will be filled with the ketorolac solution. topical bromfenac & dexamethasone Bromfenac bromfenac 0.09% eye drops twice daily starting two days before surgery and continuing 2 weeks postoperatively \& dexamethasone 0.1% eye drops four times daily starting two days before surgery and continuing four times daily during the first postoperative week and one drop less per day every following week. topical bromfenac & dexamethasone Dexamethasone bromfenac 0.09% eye drops twice daily starting two days before surgery and continuing 2 weeks postoperatively \& dexamethasone 0.1% eye drops four times daily starting two days before surgery and continuing four times daily during the first postoperative week and one drop less per day every following week. subconjunctival triamcinolone acetonide Triamcinolone Acetonide one subconjunctival injection of 10 mg triamcinolone acetonide during cataract surgery (TA, Triesence/Vistrec) in the inferotemporal quadrant, 6mm from the limbus. subconjunctival triamcinolone acetonide & intracameral ketorolac Triamcinolone Acetonide one subconjunctival injection of 10 mg triamcinolone acetonide \& intracameral injection of ketorolac tromethamine solution (Omidria; 0.023mg/mL) during cataract surgery.

2. grading aqueous flare between grade 0 \[none detectable\] up to +4 \[intense aqeous flare or fibrinous exudate\] Higher grade scores mean a worse outcome.No. of subjects with Adverse Events as a measurement of safety and tolerability Until 12 weeks postoperatively An adverse event (AE) is defined as any undesirable experience occurring to a subject during the study, whether or not considered related to the investigational product. All adverse events reported spontaneously by the subject or observed by the principal investigator or his staff will be recorded.
Most frequently reported adverse events which might occur while using the study medication: abnormal sensation in the eye, pain or irritation, redness or headache while using eye drops; increased IOP and masking of infections while using corticosteroids; abnormal sensation in the eye, pain or irritation, conjunctival hyperaemia, inflammation and corneal edema after intracameral injection with phenylephrine/ketorolac.Patient reported outcome measures (PROMs): NEI VFQ-25 Baseline and 12 weeks postoperatively Patient satisfaction and vision-specific quality of life as measured by National Eye Institute Visual Function Questionnaire (NEI VFQ-25). From 25 questions, the original numeric values given (1-10) are converted to a 0 to 100 scale, so that the scores are set between 0 points (worst outcome) and 100 points (best outcome).
Patient reported outcome measures (PROMs): Catquest-9SF Baseline and 12 weeks postoperatively Patient satisfaction and vision-specific quality of life as measured by the Catquest-9SF questionnaire. The possible range in Catquest scores are -3.94 (no difficulties) to +3.52 (great difficulties).
Patient reported outcome measures (PROMs): HUI3 Baseline and 12 weeks postoperatively Health-related quality of life as measured by HUI3 (Health Utility Index Mark 3) questionnaire. The HUI3 questionnaire consists of 8 attributes, including vision, hearing, speech, ambulation, dexterity, emotion, cognition, and pain. For each attribute, the HUI3 questionnaire provides utility (preference) scores on a generic scale where dead = 0.00 and perfect health = 1.00.
Patient reported outcome measures (PROMs): EQ-5D-5L Baseline and 12 weeks postoperatively Health-related quality of life as measured by the 5-level EQ-5D version (EQ-5D-5L) questionnaire. The EQ-5D-5L consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).
1. The EQ-5D descriptive system results in a number between 1 (best) and 5 (worse) that expresses the level selected for that dimension.
2. The EQ VAS indicates the general health status with 0 indicating the worst and 100 indicating the best health status.Quality Adjusted Life Years (QALYs) Baseline until 12 weeks postoperatively Calculated based on generic health-related quality of life, using the EQ-5D-5L and HUI-3 questionnaires
