简要总结
This real-life Health Economics and Outcome Research (HEOR) study will enable to evaluate the economic impact of Dropless therapy for the prophylactic treatment of inflammation and infection after routine cataract surgery. This prospective randomized controlled crossover open-label study will estimate resource utilization and cost attributable to patients' management following a cataract surgery and until last follow-up visit and adherence, satisfaction and preference between usual care and Dropless in a real-life setting.
Data collected will include patients' characteristics and demographics, medical information, cataract surgery information, healthcare resource utilization, patients' adherence to topical ophthalmic medications as well as patients' satisfaction to both treatment and preference between usual care and Dropless. Patients will fill a set of questionnaires at their recruitment in the study and at their last follow-up visit for their two cataracts surgery.

排除标准
- •Patients with other ophthalmic conditions such as glaucoma, corneal disease, agerelated macular degeneration, and active uveitis* (*In line with current clinical practice in Canada, uveitis should be inactive for 3 months to be included in the study);
- •Any clinically significant, serious or severe medical or psychiatric condition that may increase the risk associated with study participation;
- •Participation in any investigational ophthalmic-related drug or device trial within the 30 days prior to the start date of this trial or participation in any current investigational ophthalmic-related drug or device trial;
- •Patients with any history of allergy to the usual care post-operative eye drops or the components of Dropless.
研究组 & 干预措施
Dropless Therapy
Single used, pre-mixed, centrally compounded injectable that contains 15 mg/ml of triamcinolone acetonide and 1 mg/ml of moxifloxacin. This preservative-free suspension is injected at a dose of 0.2 mg into the posterior chamber, for a total drug delivery of 3 mg of triamcinolone acetonide and 0.2 mg of moxifloxacin. At the time of cataract surgery, Dropless is intended to be injected as a single administration into the anterior vitreous after the insertion of the IOL implant, with a 27 or 30-gauge cannula via a transzonular or transsceral pars plana injection, just before rinsing the viscoelastic fluid.
干预措施: Dropless Therapy (Combination Product)
Usual Care
This therapy usually comprises an antibiotic, a steroid and in some cases a nonsteroidal anti-inflammatory drug (NSAID). Antibacterial drops are usually given at the end of surgery and are continued for one week after the surgery. Steroid drops are usually started the day of surgery and then tapered down over 3 to 4 weeks. When prescribed, NSAIDs are usually started 2 or 3 days before surgery, or started the day of surgery, and continued for 3 or 4 times a day for 3 to 4 weeks.
干预措施: Usual Care (Drug)
