14 Clinical Trials for Various Conditions
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.
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.
The purpose of this study is to determine if there is a difference on the penetration of betadine 5% when using lidocaine 2% jelly versus topical tetracaine 0.5% in topical cataract surgery. This will be assessed comparing bacterial colony count and species by taking swabs from the eye surface before and after the topical anesthesia has been administered.
This trial will evaluate the safety and IOP -lowering efficacy of administering an iDose TR (travoprost intracameral implant) in conjunction with cataract surgery compared to cataract surgery alone
This study will compare two methods of vacuum (peristaltic or venturi) commonly used during the removal of a femtosecond treated cataract. The investigators will observe which method uses less energy, is gentler on the eye, reduces corneal swelling and if the vision recovers faster with one method compared to the other.
The purpose of this research study is to evaluate the clinical outcomes of current phacoemulsification approaches to cataract extraction involving high-frequency thermogenic energy versus the use of the MICOR System device using low-energy segment removal with a micro-interventional irrigation/aspiration port to evacuate the lens in subjects undergoing routine cataract surgery.
This study will measure the dynamic real-time intraocular pressure (IOP) in the anterior chamber during standard phacoemulsification surgery. What is known: * Fluidics control is determined to be one of the primary drivers of physician decision making in choosing phacoemulsification equipment. * Active pressure system fluidic control has a perceived and possibly real (based upon recent literature) improvement in intra-cameral IOP stability and reduced pressure fluctuations. * Improved fluidics can allow for reduced dynamic IOP fluctuations, in-the-bag positioned phaco tip, and intra-cameral fluid flow all of which will likely improve corneal health post-operatively.
The purpose of this study is to investigate postoperative events in patients noted to have retained nuclear fragments in the anterior vitreous during routine phacoemulsification and in those who did not.
The purpose of this study is to determine if Lotemax eye drops are at least as effective as Pred Forte eye drops, which are the standard of care after cataract surgery.
Incision size in cataract surgery is related to induced surgical astigmatism, chamber stability, and surgical efficiency. Sleeves of different diameters change the size of the surgical incision and amount of fluid allowed into the eye during the surgical procedure for a given set of surgical parameters. Optimization of surgical parameters requires review of surgical efficiency including: fluid usage, energy usage, and total surgical time. With optimized surgical parameters recommendations can be made to increase the efficiency and safety of cataract surgery.
The goal of this study is to determine the safety (but not efficacy in preventing infection) of sterile-packaged and pre-loaded injectable solutions of both vancomycin and moxifloxacin at certain dosages and concentrations as prepared by a compounding pharmacy when used intracamerally at the time of cataract surgery.
Nowadays cataract patient's expectations are closer to those of refractive surgery patients. Patients want to be spectacle independent. However, fifteen to twenty percent of cataract surgery patients have from 1.00 to 3.00 diopters (D) of corneal astigmatism which makes achieving spectacle independence unlikely in this patients unless the astigmatism is treated at the time of cataract surgery. Option to treat this astigmatism include corneal or limbal incisions (LRIs), the use of toric intraocular lenses (IOLs) or LASIK. Regardless of the treatment of choice to correct the astigmatism at time of cataract extraction, a treatment plan has to be calculated preoperatively. This planning include: keratometry measurements and the use of a calculator to estimate the treatment and orientation of IOL and/or placement of the LRIs. New technology has been developed and is widely used. Among this technology, we have the VERION Image Guided System. This system encompasses a reference unit that takes a picture of the eye with the patient in the sitting position creating image of the patient's eye, capturing scleral vessels, limbus and iris features. It measures keratometry as well as the corneal diameter (limbus) and pupil size. The information captured is transferred automatically to its planner where IOL power calculation and astigmatism correction calculation are completed. Additionally, intraoperative wavefront aberrometry has been used in the last couple of years with increase success.
The objective of this study is to evaluate the safety and effectiveness of the enVista® One-Piece Hydrophobic Acrylic intraocular lens (IOL), following primary implantation for the visual correction of aphakia in adults 18 years of age or older in whom the cataractous lens has been removed by an extracapsular cataract extraction method (eg, small incision phacoemulsification).
The objective of this study is to evaluate the efficacy and subject satisfaction with three different FDA approved lenses for adults over 40 years of age who desire a reduction in spectacle dependence.
