Age-Related Eye Disease Study (AREDS) Follow-Up

This study is a 5-year extension of the AREDS protocol, in which investigators followed the natural course of age-related macular degeneration (AMD) and cataracts. Participants in the former AREDS protocol are eligible for this study. Participants have a complete eye examination once a year and are contacted at least once a year between visits to check on their status. The eye examination includes measurement of visual acuity (vision chart test) and examination of the inside of the eye after the pupils have been dilated with eye drops. Photographs of the inside of the eye may be taken using a special camera that flashes a bright light in the eye. A blood sample may be obtained to test for cholesterol level and genes related to inflammation....

Participants undergoing bilateral cataract surgery will have one eye treated with the illuminated chopper and the other eye treated without the illuminated chopper, with the order randomized between eyes. The study will evaluate differences in operation time, pupil size, the need for additional intraocular medications or devices, intraoperative and postoperative complications, and postoperative clinical outcomes including visual acuity and intraocular pressure.

Randomized Controlled Trial of the STEIN Protocol: A Neuroplastic Pain Education and Guided Breathing Intervention During Awake Cataract Surgery

This randomized controlled trial evaluates whether a standardized perioperative neuroplastic intervention: the STEIN Protocol (Strategies and Techniques for Enhancing Integration and Neuroplasticity), consisting of pain neuroscience education, guided imagery, and paced breathing, reduces intraoperative analgesic and anxiolytic requirements. Secondary outcomes include patient-reported pain, anxiety, satisfaction, and postoperative recovery following cataract surgery. Reduced intraoperative sedative and analgesic requirements may reflect improved patient comfort and autonomic regulation while minimizing medication-related adverse effects.

Multimedia Education to Reduce Anxiety and Improve Care Awareness in Cataract Surgery Patients

This study aims to examine the effectiveness of multimedia health education in reducing preoperative anxiety and enhancing self-care awareness among patients undergoing outpatient cataract surgery. A randomized group design will be employed, in which participants will receive either standard preoperative education or a multimedia-based intervention covering surgical procedures, precautions, and postoperative care. Primary outcomes include levels of surgical anxiety, assessed using validated anxiety scales, and self-care knowledge evaluated through structured questionnaires. Findings are expected to inform the development of patient-centered educational strategies and enhance perioperative care quality in cataract surgery settings.

Efficacy and Safety of Tran Cannula in Combined Pseudoexfoliative Glaucoma and Cataract Surgery Compared With Augmented Ocular Irrigation

Pseudoexfoliative glaucoma is a glaucoma secondary to pseudoexfoliative syndrome; cataract surgery is often more difficult, with more complications. Tran's cannula is a single-use irrigation system designed for cleaning, with the pseudoexfoliative material remaining in the trabecular meshwork. The main objective of this study is to evaluate the efficacy of the Tran cannula, in comparison with increased irrigation, in lowering intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma and treated for glaucoma, and with an indication for isolated cataract surgery.

Prospective, randomized, multicenter, multi-arm, subject and vision-assessor-masked, two stage study with Stage 1 as a three-arm initial enrollment period, followed by Stage 2 as a head-to-head study refined based on the Stage 1 data.

Evaluating a Dropless Postoperative Regimen After Cataract Surgery in a Vulnerable, County-hospital Population

The current postoperative cataract surgery eye drop regimen used at Zuckerberg San Francisco General Hospital (ZSFG) is a significant burden for its patient population, contributing to high rates of non-adherence and the development of postoperative complications. The investigators propose to replace this complex regimen with a single administration of intraocular antibiotic and subconjunctival steroid at the time of surgery. This pilot study will obtain the preliminary data required to eventually fully evaluate this innovation in postoperative care in a safety-net population with respect to postoperative outcomes, patient compliance, and patient and caregiver satisfaction.

Long-term Safety & Performance of REVISYON SDS100 in Mild to Moderate Cataract: Extension Study (EB-CE-02)

A non-interventional, extension study on the long-term maintenance of safety and performance of the REVISYON SDS 100 medical device in subjects with mild-to-moderate cataract.

Evaluation of Safety and Effectiveness of an IOL With a Virtual Aperture Optic

Cataracts are cloudy areas in the lens of the eye that can cause changes in vision. Symptoms of cataracts include cloudy or fuzzy vision and sensitivity to glare. Cataract extraction with Intraocular lens (IOL) implantation is the most commonly performed surgical procedure in the world. Presbyopia affects almost everyone over the age of 50. With age, the natural crystalline lens loses its ability to change shape, or accommodate, to focus on near distances. Thus, individuals with excellent distance vision will still need to wear spectacles for near tasks such as reading, and intermediate tasks such as computer work.

The Effect of Topical Rho-kinase Inhibitors on Corneas of Patients With Fuchs Endothelial Corneal Dystrophy

The goal of this study is to learn if topical ROCK inhibitors protect endothelial corneal cells in patients with glaucoma and Fuchs endothelial corneal dystrophy after cataract surgery. The main question it aims to answer is: do topical ROCK inhibitors decrease the loss of corneal endothelial cells after cataract surgery? Researchers will compare topical ROCK inhibitor to a placebo (a look-alike substance that contains no drug) Participants will: Take topical ROCK inhibitor or a placebo every day for 4 weeks after cataract surgery and visit the clinic for checkups and tests.

Bilateral Monofocal Versus Monofocal-EDOF IOL Implantation: Quality of Vision Comparison

The goal of this clinical trial is to compare visual quality after cataract surgery between two groups: bilateral monofocal intraocular lenses (IOL) and monofocal and contralateral extended depth-of-focus (EDOF) IOL implantation. The main question it aims to answer is: • does the combination of both monofocal and EDOF IOLs presents an advantage over bilateral monofocal IOL implantation in the daily life of patients undergoing cataract surgery without the disadvantages of bilateral EDOF IOL implantation? Participants will: * be randomised in either bilateral monofocal group or monofocal and EDOF group * undergo visual acuity testing with and without correction at all distances * be asked to complete a quality of vision questionnaire * undergo non-invasive examinations to measure residual astigmatism, contrast sensitivity, straylight, optical aberrations, reading spead.

Partial Range Of Field IOLs in DMEK-Enabled Procedures

Study Overview This study aims to evaluate the visual outcomes, quality of vision, and patient satisfaction after receiving an extended range PRoF intraocular lens (IOL) during triple Descemet Membrane Endothelial Keratoplasty (DMEK) surgery. This surgery is typically performed to treat patients with both corneal endothelial dysfunction and cataracts. By testing a newer IOL, the PureSee™ extended PRoF IOL, this study hopes to improve the way ophthalmologists plan surgeries and select IOLs for these patients, ultimately helping surgeons optimize the results and expand the options available for people undergoing this procedure. Purpose of the Study The goal of this study is to evaluate how well the PureSee™ IOL works in terms of intermediate visual acuity (how well participants can see things at an arm's length). The investigators will also measure the quality of vision, satisfaction, and whether participants need glasses after surgery. The investigators have set the following goals for this study: Primary Goal: To measure how well patients can see intermediate distances (uncorrected intermediate visual acuity, or UIVA) after receiving the PureSee™ IOL during triple DMEK surgery. Secondary Goals: To understand how independent patients are from glasses after surgery. To measure patients' uncorrected and best-corrected visual acuity (sharpness of vision) at distance, intermediate, and near vision after surgery. To evaluate the uncorrected defocus curve (how the vision of participants changes when focusing at different distances). To measure contrast sensitivity (how well participants can see in low-light conditions or with subtle contrasts). Who Can Join This Study? To participate in this study, participants need to: Be undergoing triple DMEK surgery for endothelial dysfunction and cataract at the time of enrollment. Be eligible to receive an extended range of vision IOL as part of the procedure. This study is looking for patients who are interested in understanding how new IOL technology might improve their postoperative vision quality and reduce their dependence on glasses. What Will Happen During the Study? Participants will have their visual outcomes and satisfaction measured at specific times following surgery. This includes: Testing uncorrected and best-corrected visual acuity at several distances (distance, intermediate, and near). Completing a survey about how satisfied they are with their vision and how often they need glasses or contact lenses. Undergoing testing to measure contrast sensitivity (how well participants can see in low-light conditions). Why Is This Study Important? The results of this study will help doctors make better decisions about which IOLs to use during triple DMEK surgery. By evaluating the PureSee™ extended PRoF IOL, the investigators hope to expand options for patients and potentially improve visual outcomes and postoperative satisfaction. Ultimately, this study could help improve the quality of life for patients who have both cataracts and endothelial dysfunction. Study Duration Participants can expect to undergo their last assessment 6 months post-surgery to track their progress.

Dexamethasone Versus Metoclopramide for Prophylaxis of Nausea and Vomiting After Cataract Surgery

Postoperative nausea and vomiting (PONV) is a common consequence of ambulatory surgery, affecting up to 80% of high-risk patients and 20-30% overall. Despite being widespread, a prior survey found that patients are more averse to PONV than pain and other significant postoperative problems. Furthermore, even mild cases of PONV can have serious repercussions, such as postanesthesia care unit (PACU) workflow disruption, delayed discharges, higher medical costs, and lower patient satisfaction.PONV following intraocular surgery can be unpleasant and may lead to serious complications including suprachoroidal hemorrhage (SCH). SCH is a potentially serious condition that occurs when the posterior ciliary arteries or vortex veins burst, resulting in blood in the suprachoroidal region. The hypothesis is that dexamethasone will lower the incidence of PONV after cataract surgery when compared with metoclopramide.

3D Visualization System in Highly Myopic Cataract Operation

This study aims to investigate the impact of depth of field differences between the use of the 3D imaging system (NGENUITY® 3D Visualization System, Alcon, TX, USA) and conventional optical microscope in cataract surgery for highly myopic patients on intraoperative parameters and outcomes.

Personalized Music for Anxiety During Cataract Surgery

This randomized controlled trial evaluated the effect of a personalized music intervention on anxiety and pain in patients undergoing cataract surgery under local anesthesia. A total of 100 patients were randomly assigned to an intervention group or a control group. Patients in the intervention group received a structured personalized music intervention during surgery based on their musical preferences, while patients in the control group received standard care. Anxiety was assessed before and immediately after surgery using the State-Trait Anxiety Inventory-State (STAI-S), and pain was assessed immediately after surgery and two hours after surgery using the Visual Analog Scale (VAS). The study aimed to determine whether personalized music provided during cataract surgery could reduce patients' anxiety and pain compared with standard care.

Corneal Biomechanics and Surgically Induced Astigmatism in Pseudoexfoliation Syndrome

This prospective study aims to evaluate the influence of corneal biomechanical properties on surgically induced astigmatism following standard phacoemulsification cataract surgery in patients with pseudoexfoliation syndrome compared with patients without pseudoexfoliation. Corneal hysteresis (CH), corneal resistance factor (CRF) and corneal astigmatism will be measured before surgery and at postoperative follow-up visits. The relationship between changes in corneal biomechanics and surgically induced astigmatism will be analyzed.
