46 Clinical Trials for Various Conditions
A study to evaluate the real-world clinical performance of the enVista Aspire and Aspire Toric intraocular lens (IOL) models EA and ETA and to assess surgeon and subject satisfaction
The goal of this clinical trial is to learn if MELT-300 works on procedural sedation in adult participants undergoing cataract extraction with lens replacement (CELR). It will also learn about the safety of MELT-300. Researchers will compare MELT-300 to a placebo (a look-alike substance that contains no drug) to see if MELT-300 works on procedural sedation in adult participants undergoing CELR. Researchers will also include a comparator SL midazolam to confirm the benefit of inclusion of ketamine in the combined drug product. The main questions it aims to answer are: 1. Does MELT-300 is effective in comparison to placebo on procedural sedation for cataract surgery? 2. To determine the effectiveness of MELT-300 compared with midazolam on procedural sedation (to determine the contribution of ketamine component and inform the risk of ketamine in MELT-300) 3. To determine the time to achieve preoperative target sedation level with MELT-300 4. What medical problems do participants have when taking MELT-300 vs placebo Eligible participants will admitted to the study unit on Day 1. Participants will be randomized prior to surgery 4:1:1 to 1. MELT-300 (i.e. 1 MELT-300 sublingual tablet which contains 3 mg midazolam and 50 mg of ketamine) 2. Midazolam (i.e. 1 matching midazolam sublingual tablet which contains 3 mg midazolam) 3. Placebo (i.e. 1 matching placebo sublingual tablet) Participants will receive study medication 30 (± 5) minutes, without food or water, before planned surgery start (defined as instillation of topical ocular anesthetic gel \[i.e.. 3 drops of chloroprocaine hydrochloride ophthalmic gel)\]. The effectiveness of MELT-300 will be performed after study medication is administered before surgery, in the course of surgery, and postoperative on Day 1 (end of surgery defined as just prior to drape removal). The safety of MELT-300 will be performed at baseline, in the course of surgery, postoperatively on Day 1, and on Day 3 ± 1 day post dose of study medication.
A Study to Evaluate the enVista® Aspire (EA) intraocular lens in Subjects Undergoing Cataract Extraction
This research study is evaluating the safety and efficacy (performance) of the Bausch + Lomb enVista Beyond Hydrophobic Acrylic Extended Depth of Focus Intraocular Lens (IOL) in subjects who receive this IOL in both eyes.
The goal of this clinical trial is to demonstrate the safety and effectiveness of the full visual range AT ELANA 841P IOL when used to treat adult patients having cataract surgery. Subjects will be randomly selected to receive a pair of IOLs, either the AT ELANA 841P or CT LUCIA 621P lens design. All patients will undergo surgery in both eyes, and they will receive follow up care for up to 6-months. During this time, all patients will undergo thorough eye exams at every study visit and complete questionnaires about their quality of vision post-surgery.
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 primary purpose of the study is to evaluate the efficacy and safety of MELT-300 (Midazolam and Ketamine Sublingual Tablets) and the contribution of midazolam and ketamine components to sedation and during the surgery or ocular analgesia in participants undergoing cataract surgery with lens replacement.
The purpose of this research study is to evaluate the clinical outcomes of the use of low-energy segment removal with a micro-interventional irrigation/aspiration port (MICOR-304) to evacuate the lens prior to intraocular lens insertion in subjects undergoing routine cataract surgery.
Assessing DEXTENZA efficacy when placed within the upper eyelid canaliculus as opposed to the lower eyelid canaliculus.
The objective of this study is to evaluate the uncorrected binocular distance, intermediate, and near visual acuities, and assess patient's spectacle independence and satisfaction in individuals undergoing bilateral cataract extraction that have received two different arms of near add design IOLs of the same diffractive multifocal model.
The purpose of this study is to compare the safety and efficacy of goniotomy performed with a novel ophthalmic knife compared to trabecular bypass stent implantation in mild to moderate glaucoma subjects who are also undergoing cataract extraction with phacoemulsification (Phaco) and posterior chamber intraocular lens (PCIOL) implant.
The purpose of this study is to evaluate the effect of OMS302 compared to phenylephrine when administered in irrigation solution during cataract extraction on intraoperative pupil diameter, acute postoperative pain, and safety in children birth through 3 years.
The study objective is to assess changes in corneal sensation and dry eye signs and symptoms following cataract extraction/femtosecond arcuate relaxing incisions. Our clinical hypothesis is to determine if a combination of cataract surgery and femtosecond arcuate relaxing incisions lead to a reduction in corneal sensation and the onset or worsening of dry eye signs and symptoms.
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 purpose of this study is to determine whether the use of OMS302 (the study drug) in individuals undergoing Cataract Extraction with Lens Replacement (CELR) surgery is safe and effective at maintaining an adequately dilated pupil during surgery and reducing post-operative symptoms of discomfort (such as eye pain and irritation).
This is a multicenter evaluation of the effects of the cataract extraction and limbal relaxing incisions (LRI) on corneal sensation and dry eye signs and symptoms.
Evaluation of glistenings in intraocular lenses implanted in normal patients following routine cataract surgery. The lenses used will be Model X-60 made by the AVS company Vs AcrySof MA50BM made by the Alcon company.
Two very common aging-related diseases in older adults are Alzheimer's disease (AD) and cataracts. In elderly adults, these two diseases frequently occur in the same person. Although a cure for AD is currently unavailable, cataracts can be effectively treated with surgery in most people. The removal of cataracts has documented benefits for visual performance and for reducing accidents and falls. However, it has been the experience of the ophthalmologists, and others in the field, that patients, caregivers, and primary care doctors are reluctant to proceed with cataract surgery once an individual is given the diagnosis of AD. It is thought that cataract surgery will not improve the AD patient's quality of life, vision, and cognition. The investigators have designed this study to determine whether or not this is true.
This is an exploratory study to determine the safety and clinical benefit of OMS302 Injection in subjects undergoing Cataract Extraction with Lens Replacement (CELR) using a coaxial phacoemulsification process.

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 evaluates the safety and effectiveness of a capsular tension ring (CTR) when used during cataract surgery. Capsular Tension Rings are used during intraocular lens implantation to give added support in order to keep the intraocular lens well centered, especially in eyes with weak or partially absent zonules. In many cases, capsular tension rings allow a lens to be successfully implanted into an eye which otherwise could not have supported an intraocular lens.
