These devices are approved by the US Food and Drug Administration (FDA).
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.
The goal of the study is to prospectively evaluate and compare Hydrus microstent to the iStent Inject Wide in combination with cataract surgery in patients with mild to moderate open angle glaucoma. Hydrus and iStent are the two FDA approved trabecular meshwork targeting microstents to treat open angle glaucoma in conjunction with cataract surgery.
This prospective interventional single-arm trial evaluates measures changes in ocular surface disease parameters in eyes with mild to moderate open-angle glaucoma (OAG) on 1-4 glaucoma medications who undergo phacoemulsification and trabecular micro-bypass stent(s) implantation (iStent or iStent inject).
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 primary objective of this study is to compare the efficacy of antecedent intravitreal anti-vascular endothelial growth factor therapy vs. Ozurdex in reducing post-cataract surgery related macular edema in patients with pre-existing diabetic macular edema.
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.
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 Lotemax eye drops are at least as effective as Pred Forte eye drops, which are the standard of care after cataract surgery.
Approximately 50 patients undergoing cataract surgery will be randomized in an even allocation (1:1) into two treatment groups, either ketorolac 0.45% BID or bromfenac 0.09% BID. Patients will be instructed to begin dosing study medication in the operative eye the day before surgery and continue dosing until day 14. KOWA flare measurements will be performed at postoperative day one and postoperative day 14. The amount of anterior chamber inflammation (flare) will be objectively measured.
Approximately 126 subjects scheduled to undergo cataract surgery by phacoemulsification, will be randomized in an even allocation (1:1:1) to either Acuvail, Xibrom, or Nevanac. Subjects will be instructed to begin dosing the study medication in the operative eye the day before surgery and continue dosing on the day of surgery. Beginning one hour before surgery, 1 drop of study medication will be instilled by operating room staff approximately every 15 minutes for a total of 3 doses. At the designated time a paracentesis will be performed at the start of the cataract procedure and at least 0.15 cc of aqueous humor will be collected. The sample will be immediately stored on dry ice and shipped to a laboratory for analysis.
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.
The purpose of this study is to compare the safety \& effectiveness of the two types of cataract and glaucoma surgeries. Results from this study may improve the surgical and post surgical management and long term management of patients with these conditions in the future
The purpose of this study is to evaluate the visual outcomes, amount of inflammation, endothelial cell loss, and the efficiency of a torsional handpiece compared to a conventional handpiece during surgery to remove your cataracts.
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.
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
The goal of this clinical trial is to investigate the early post-operative benefits of performing phacoemulsification at physiologic intraocular pressures. The main questions it aims to answer are: * Is there less post operative corneal edema? * Is there less post operative inflammation? * Is the post operative vision better? Participants will undergo phacoemulsification cataract surgery with either high or low IOP settings Researchers will compare post op corneal edema, inflammatory marker levels and vision
The primary purpose of this study is to compare the Clareon/Clareon Toric Intraocular Lenses (IOLs) to the Eyhance/Eyhance Toric IOLs in binocular Best Corrected Distance Visual Acuity (BCDVA) at 3 months postoperative.
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.
