Filter by:In this project, the investigators aim to compare the safety, efficacy, and predictability outcomes of conventional CEIOL surgery to Femtosecond-laser-assisted CEIOL (FLACS) in an effort to improve cataract surgery outcomes. The investigators hypothesis is that FLACS may lead to preservation of endothelial cells compared to conventional CE IOL.
To compare the efficiency of surgical procedures using 2 phaco tip designs in torsional phacoemulsification using the bevel-down technique.
The objective of the study was to evaluate the safety and efficacy of OTX-DP (dexamethasone insert) 0.4 mg for intracanalicular use when placed in the canaliculus of the eyelid for the treatment of post-surgical inflammation and pain in subjects who had undergone cataract extraction with intraocular lens implantation
To compare the anti-inflammatory efficacy of ketorolac of tromethamine 0.4% and nepafenac 0.1% eye drops for prophylaxis of cystoid macular edema (CME) after small-incision cataract extraction.
The primary purpose of the study was to compare the macular hole closure and visual acuity gain following vitrectomy using SF6 gas tamponade with 7 days of face-down positioning versus C3F8 gas tamponade with 14 days of face-down positioning. The secondary purpose was to report, in each group, the cumulative incidence of cataract development 1 year following macular hole surgery and the proportion of complications (*). ((*) hypertony, hypotony, retinal tear, retinal detachment and endophthalmitis) This prospective randomized study examined a 3 year period. The first patient was included in January 2010 and the last in November 2011. The 12-month follow-up spread out from March 2011 to December 2012. The first group included 31 patients who had undergone macular hole surgery using SF6 gas and who were advised to stay in face-down position for 7 days postoperatively (SF6 group). These patients were compared to 28 patients who had undergone macular hole surgery with C3F8 gas and who were advised to maintain a face-down position for 14 days. Patients in both groups underwent vitrectomy, internal limiting membrane peeling, and fluid-gas exchange using either SF6 or C3F8. Preoperative data included the characterization of the hole with Optical Coherence Tomography (OCT), the best correct visual acuity (VA) recorded in number of letters using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart, classification of the cataract according to the LOCS III and the intraocular pressure IOP. Postoperative data included OCT confirmation of the closure at 6 weeks and 1 year, 1 year's best corrected VA recorded in number of letters (EDTRS chart) and determination of cataract development and extraction as needed.
The principal objective of the study is to determine the visual acuity at far, intermediate and near distances tested with optotypes at different distances from the eyes and tested with defocus addition lenses of patients implanted bilaterally with the POD 26P AY FineVision. Secondary objective will be to test the glare and contrast sensitivity.
This study was conducted to evaluate changes of reduction of corneal astigmatism with toric intraocular lens(IOL) in congenital cataract.
This study will evaluate the effect of sodium carboxymethylcellulose eye drops in the treatment of dry eye after cataract surgery.
Purpose of The Study: The purpose of this study is the following: A)To gather age-related normative visual acuity data for the Vimetrics Central Vision Analyzer (CVA, Vimetrics, LLC, Media, Pa) B)To gather visual acuity data for patients with known ocular problems, including cataract and maculopathy. C)To correlate and compare the CVA visual acuity findings with the acuity measured with standard LogMAR acuity charts viewed under similar conditions of contrast and lighting
The purpose of this multicenter, prospective, randomized clinical study is to determine the safety and effectiveness of the EYEFILL® C.-US Viscoelastic in patients undergoing cataract extraction and intraocular lens (IOL) implantation surgery. EYEFILL® C.-US Viscoelastic is designed to create and maintain space, to protect the corneal endothelium and other intraocular tissues, and to manipulate tissues during surgery. EYEFILL® C.-US Viscoelastic may also be used to coat intraocular lenses and instruments during cataract extraction and intraocular lens insertion.
