Filter by:The purpose of this post-market clinical follow up study is to assess the safety and effectiveness of the SPRING THREAD® elastic tensor thread. The study will evaluate the outcome of the SPRING THREAD® elastic tensor thread range over a period of 5 years.
The purpose of this study is to compare the results of vision tests that are algorithmically derived and delivered through a virtual reality headset with those delivered through the existing technology standards (eg. Humphrey for field tests). Tests that the researchers will be conducting include vision field perimetry, Amsler, acuity chart, contrast- sensitivity and currently used office tests.
Glaucoma represents a group of conditions that cause damage to the optic nerve and can lead to irreversible vision loss. Current treatments are aimed at lowering intraocular pressure while minimizing medication side effects. Lumify™ (Brimonidine Tartrate Ophthalmic Solution 0.025%) is an FDA-approved medication for alleviating eye redness, a common side effect of glaucoma medications. The purpose of this study is to evaluate the effect of Lumify™ on eye redness, intraocular pressure, and eyelid position in patients with glaucoma who are already using the Brimonidine 0.1%, 0.15% or 0.2% eye drops.
This study is being conducted to determine whether the use of bandage contact lens after ptosis surgery provides any benefits for the patient or is unnecessary.
The objective of this study is to investigate quantitative improvement in excessive tearing after administration of Bupivacaine, a local anesthetic, into the affected eyelids.
Blepharoptosis (ptosis) repair is a common and generally well tolerated surgical procedure usually performed using local anesthetic. However, a subset of patients appears to experience intraoperative pain/discomfort during ptosis repair using an anterior approach with subcutaneous local anesthetic. Posterior subconjuctival local anesthetic is currently used for eyelid procedures such as chalazion incision and drainage and full-thickness eyelid resections. The purpose of this study is to determine whether an additional subconjunctival injection of local anesthetic, through the posterior aspect of the eyelid, reduces intraoperative pain during anterior ptosis repair.
Interventional , multicenter , comparative study. One eye receiving the cells and the contralateral eye as a negative control . If effectiveness following review of the primary endpoint and the advice of an independent expert committee , the experimental treatment will be offered to the patient to the contralateral eyelid. Objective is to restore muscle function levator muscle of the upper eyelid by providing a registry of autologous myoblasts from a non- clinically affected muscle .
The aim of this study is to show that the performance of Novosyn® Quick suture material is comparable with standard suture material used in Ophthalmic surgery. In order to show that, various safety and efficacy parameters have been selected. The outcome regarding these parameters will be compared in 2 treatment groups. Active control group will receive Vicryl® Rapide and the treatment group Novosyn® Quick for ophthalmic surgery. It was decided to design this study as a randomized trial, because limited clinical evidence is available in the literature for the active control group (Vicryl® Rapide) which can be used for comparison. Eye operation will be randomly allocated on the left and right side (1:1) to both treatment groups. Patients undergoing elective, primary ophthalmic surgery (dacryocystorhinostomy, ectropion, entropion, ptosis, eyelid tumor resection, blepharoplasty)
The investigators aim to assess the effect of blepharoplasty with or without muller muscle resection on the symptoms of dry eye syndrome. this will be an observational study in which patients undergoing the aforementioned surgeries will be followed up and monitored for dry eye symptoms.
The purpose of this study is to assess a new technique of measurement for the levator muscle. this measurement may be applied during a clinical evaluation of eyelid malposition. our purpose is to quantify the levator muscle strength and to corelate it to standard levator muscle strength assessment techniques routinley used in the oculoplastic clinic.
