Active clinical trials for "Cataract"

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.

An observational study aiming to assess the incidence and possible causes of post phacoemulsification watery eye.

Presbyopia-correcting implant (PC-IOL): AcrySof IQ Vivity (Alcon) has been evaluated in 2 large pivotal trials (US and OUS trials). These tests showed that this PC-IOL restored intermediate visual acuity (IVA) and near visual acuity (NV A) superior to that of the reference monofocal AcrySof implant. In these tests, it was demonstrated that distance visual acuity (DVA) was non-inferior. However, the intermediate visual acuity for this implant in its toric version has not been evaluated.

A prospective evaluation of postoperative corneal aberrations and visual parameters (e.g. visual acuity) in patients implanted with an AcrySof Toric IOL.

A multi-disciplinary intervention will reduce inappropriate preoperative testing for cataract surgery. Despite multiple rigorous randomized controlled trials and meta-analyses showing that pre-operative testing for cataract surgery does not improve outcomes, pre-operative testing has not declined. A quality improvement initiative, which includes gaining senior leadership support, changing the culture of care, and elimination of pre-operative consultation visits for cataract surgery, to reduce inappropriate pre-operative testing. Quasi-experimental difference-in-difference analysis comparing the intervention arm (LAC+USC Medical Center) with the control arm (Harbor-UCLA Medical Center), 6 months prior and 6 months after the intervention. Generalized estimating equation models will adjust for age, gender, race/ethnicity, comorbidities and cluster by site.

Nalbuphine has been used as an adjuvant to bupivacaine in intrathecal, epidural, caudal anesthesia and peripheral nerve blocks showing an increase in the efficacy and the duration of postoperative analgesia.The aim of this study is evaluation of the effect of nalbuphine when used as an adjuvant to a local anesthetic mixture in peribulbar block undergoing cataract surgery

Comparative safety study of intracameral levofloxacin versus moxifloxacin for postoperative infection prophylaxis

The objective of this study is to evaluate the safety and effectiveness of an investigational IOL in providing a range of vision as compared to a commercially available trifocal IOL in subjects undergoing cataract extraction and IOL implantation.

Cataract surgery is commonly performed in elderly patients who are at high risk for developing postoperative cognitive dysfunction. Most cataract surgeries are performed under peribulbar or retrobulbar anesthesia, however, most of the patients require sedation to relieve the perioperative anxiety and induce amnesia. So, many sedative agents can be used especially benzodiazepines which may increase the risk of developing postoperative cognitive dysfunction. Ketamine can be used as a sedative and analgesic agent in a dose of 0.25 -0.5 mg/kg with certain studies suggesting that it may decrease the risk of postoperative cognitive dysfunction. Similarly, dexmedetomidine can be used as a sedative and analgesic agent with the possibility of decreasing the incidence of postoperative cognitive dysfunction. this controlled study will compare the effect of ketamine or dexmedetomidine on the POCD of patients undergoing cataract surgery.
