NCT ID: NCT04412525 Completed - Clinical trials for Vitreoretinal Surgery

Comparative Study 27G Vitrectomy vs Larger Gauge Surgery

Start date: June 5, 2020
Phase: N/A
Study type: Interventional

Two-arm, mono-center, prospective, interventional comparative case study to compare postoperative recovery between the 27G and larger gauge surgical approach.

NCT ID: NCT04371445 Enrolling by invitation - Post-operative Pain Clinical Trials

Dextenza in the Post-op Management of Vitreoretinal Surgeries

Start date: December 1, 2020
Phase: Phase 4
Study type: Interventional

This study will assess the control of inflammation at days 1, 7, 14, and 21 days following the vitreoretinal surgical procedure analyzing two randomized study arms: Intracanalicular dexamethasone insert group or topical steroid drop group. Patients must be 18 years of age and older, of any race and either sex, requiring surgery with the procedure type of pars plana vitrectomy for either the indication of macular hole, epiretinal membrane removal, or vitreomacular traction.

NCT ID: NCT04216108 Completed - Clinical trials for Vitreoretinal Surgery

Comparative Study 23G Versus 27G Vitrectomy

23Gvs27G
Start date: December 1, 2018
Phase: N/A
Study type: Interventional

Investigator-initiated, comparative double-arm, mono-center, prospective, interventional case study to determine whether ultra-small gauge surgery (27G gauge needle) improves postoperative outcome and patient morbidity.

NCT ID: NCT03390244 Completed - Clinical trials for Vitreoretinal Surgery

Foldable Capsular Vitreous Body Implantation Study

FCVB
Start date: May 2, 2017
Phase: N/A
Study type: Interventional

This study is intended to evaluate the clinical usefulness of the FCVB in its on-label use, but in a different racial type than studies till now (Asians only). The device will be inserted in Caucasian patients with permanent loss of functional vision (visual acuity hand movements or less), where a permanent use of repeat silicone oil is required to maintain the eye pressure.

NCT ID: NCT03189329 Completed - Clinical trials for Cognitive Function Abnormal

The Effect of Retrobulbar Block for Eye Surgery on Brain Oxygenation and Cognitive Functions in Elderly Patients

Start date: January 2015
Phase: Phase 4
Study type: Interventional

The investigators measured changes in cerebral oxygen saturation (rSO2) and MMSE scores after retrobulbar block performed with levobupivacaine and lidocaine in patients undergoing vitreoretinal surgery.A total of 66 patients over the age of 60 undergoing vitreoretinal surgery with a total duration of less than 1 hour were included in this prospective, double-blinded study. The patients were randomly divided into two groups: group L (5ml, 2% lidocaine) and group LB (5ml, 0.5% levobupivacaine). Bilateral rSO2 measurements were recorded before the retrobulbar block and at 1-5 minutes post-block, during the procedure, and at 10-40 minutes post-op. MMSE was performed preoperatively and postoperatively in order to evaluate short term cognitive function. Sensory and motor block durations, pain, akinesia and conjunctival feeling scores, patient-surgeon satisfaction, and complications were also recorded.

NCT ID: NCT02324166 Not yet recruiting - Endophthalmitis Clinical Trials

Cefazolin-Lidocaine Combination Solution to Reduce Antibiotic Pain

Start date: January 2015
Phase: Phase 4
Study type: Interventional

In retinal surgery, endophthalmitis is a sight-threatening eye infection that could complicate patient vision after the operation. At Toronto Western Hospital, for retinal surgery (operating at the back of the eye) it is common practice to administer an antibiotic (cefazolin) at the end of surgery, to reduce the risk of post-operative endophthalmitis. The antibiotic is administered by injection underneath the part of the eye called the conjunctiva. However, this antibiotic injection is often associated with high levels of post-operative pain. Previous studies have observed a reduction of this pain by injecting an anesthetic (lidocaine) in the subconjunctival space before the antibiotic. This study will seek to examine whether mixing 2% lidocaine with cefazolin before its injection will reduce post-operative pain in the retinal surgery setting.

NCT ID: NCT01083004 Recruiting - Macular Hole Clinical Trials

Brilliant Blue Versus Indocyanine Green

Start date: January 2008
Phase: Phase 3
Study type: Interventional

A study of non-inferiority design comparing brilliant blue and indocyanine green as intraoperative dye in macular pucker and macular hole.
