Filter by:To evaluate the safety and efficacy of ocular iontophoresis with dexamethasone phosphate ophthalmic solution, EGP-437®, using the EyeGate® II Drug Delivery System (EGDS) in patients having undergone cataract surgery with implantation of a posterior chamber intraocular lens (IOL)
This study will compare cataract patients before and after phacoemulsification. Evaluations will be performed before and 1 and 3 months following cataract surgery, including measurement of tear film lipid layer thickness, tear film break up time, Schirmer test, corneal and conjunctival fluorescein staining, examination of lid margins and meibomian glands, and the Ocular Surface Disease Index.
This study is a prospective, multicenter, bilateral, non-randomized, open-label, comparative clinical study conducted at up to 80 sites in the USA. Subjects will choose to be bilaterally implanted with either 1) the TECNIS 1-Piece Toric IOLs, Model ZCT300 and/or ZCT400, or 2) the TECNIS Monofocal Model ZCB00 non-toric control IOL, according to subject preference
The study design will be a prospective study comparing laser-assisted cataract extraction cases and traditional manual phacoemulsification cases. All cases will be performed by faculty-supervised residents at Parkland Memorial Hospital. This study aims to examine visual acuity and complication rates in femtosecond laser-assisted cataract surgery compared to traditional manual phacoemulsification cataract surgery for the beginning surgeon. In addition, this study will assess the subjective novice surgeon experience and the patient experience in terms of expectations and results.
The purpose of this study is to compare the Technology-based Eye Care Services (TECS) protocol to the standard face to face ophthalmologic exam.
Primary objective of the study is the assessment of the patients' discomfort and ocular redness following cataract extraction surgery by means of phacoemulsification and intraocular lens implantation.
The study is a prospective, randomized, parallel-design, multicenter trial in patients ≥40 years of age undergoing cataract surgery. Patients who meet all inclusion and no exclusion criteria will be randomized to 1 of 2 treatment groups - A single 5 mcl anterior chamber injection of IBI 10090, 103.4 mcg/mcl dexamethasone, equivalent dexamethasone dose: 517 mcg at the conclusion of cataract surgery or; - Prednisolone acetate ophthalmic suspension 1% eye drops administered 1 drop 4 times daily (QID) for 3 weeks Safety will be assessed by adverse events (AEs), slit lamp biomicroscopy, fundus examination, intraocular pressure (IOP), visual acuity, and specular microscopy endothelial cell count.
Cataract is the clouding of the lens of the eye, which initially prevents clear vision and eventually progresses to blindness if left untreated. Cataract remains the leading cause of blindness and an important cause of visual impairment across the globe. Cataract surgery by ultrasonic phacoemulsification is the most common surgery practiced in France (600 000/year) Two sub-categories of phacoemulsification coexist : Endocapsulars techniques represented by Divide-and-Conquer and Phaco-Chop ; and Supracapsular techniques mainly represented by Subluxation (similar to Tilt-and-Tumble) The corneal endothelium plays an important role in maintaining the dehydrated state and the transparency of the cornea. Some degree of endothelial cell loss invariably occurs in all types of cataract surgery but the amount of endothelial cell loss may varies with the type of surgical technique The aim of the study is to evaluate the density of the central corneal endothelial cells before and after cataract surgery comparing two phacoemulsification techniques (Divide-and-Conquer vs Subluxation)
The purpose of this study is to investigate visual outcomes and assess safety at 12 months (330-420 days) post bilateral implantation of the AcrySof® IQ PanOptix™ Presbyopia-Correcting IOL.
The investigators aim to conduct a prospective clinical pilot study to investigate the use of VisionBlue staining administered during cataract surgery to 20 patients with history of trabeculectomy for glaucoma as a means to assess functioning of an existing filtering bleb. The investigators also aim to develop a standard classification system for assessing filtering bleb function during cataract surgery.
