Active clinical trials for "Cataract"

In this randomized clinical trial, patients with concomitant glaucoma and cataract candidate for non-penetrating deep sclerectomy (NPDS) and phacoemulsification (PE) and subtenon mitomycin injection will be enrolled. Patients will randomly be allocated to two groups ["NPDS and PE and autotransplantation of human anterior lens capsule (ALC)" and "NPDS and PE" alone]. Exclusion criteria will be the patients with prior ocular surgery, neovascular glaucoma, uveitis, or compromised ocular surface. The intervention group will be undergoing NPDS and PE with the use of an ALC as the spacer in the intrascleral lake. The control group will be undergoing NPDS and PE without any spacer. The primary outcome will be intraocular pressure measured on days 1, 3, 7, months 1, 3, 6, and 12. The secondary outcomes will be surgical success rate (complete and qualified), the number of glaucoma medications, best-corrected visual acuity, surgical complications, and the need for needling and laser goniopuncture measured at the same intervals. The complete success rate will be defined as intraocular pressure less than 18 mmHg with a 20 percent reduction without anti-glaucoma medication. The qualified success rate will be defined as intraocular pressure less than 18 mmHg with a 20 percent reduction with anti-glaucoma medication.

There is strong consensus - based on robust randomized trial data - that routine pre-operative (pre-op) testing for cataract surgery is inappropriate. Despite these widely endorsed evidence-based recommendations, most seniors undergoing cataract surgery still receive unnecessary blood testing, EKGs, and chest X-rays (CXRs); another substantial percentage even undergo nonindicated cardiac stress tests. We will integrate three new best practice alert (BPA) nudges into the University of California, Los Angeles (UCLA) Health electronic health record (EHR). The nudges are informed by behavioral economic theory and are designed to alter the choice architecture for physicians to decrease the rate of pre-op test ordering while still preserving clinician autonomy. We will conduct a pragmatic trial to evaluate whether these BPA nudges reduce low-value pre-op testing for cataract surgery.

The aim of this study was to determine the effect of relaxation exercises applied before cataract surgery on the anxiety level of elderly individuals.

Analyse the peripheral vision after cataract surgery with a new IOL compared to a standard IOL

This is a prospective randomised open-label study with the aim to compare the visual performance of the premium monofocal Isopure IOL versus the extended depth of focus Eyhance® IOL after phaco-emulsification cataract surgery.

The goal of this study is to assess any post operative cognitive changes following benzodiazepine administration during cataract surgery. The investigators will compare effects of Midazolam vs. Remimazolam on cognition at the time of discharge from the post operative care unit and the next day following surgery. Cognitive changes will be assessed by administration of Montreal Cognitive Assessment (MoCA). Participants will: Complete MoCA testing prior to surgery Randomize in either Midazolam or study drug Remimazolam Complete MoCA testing after surgery at the time of discharge in the post anesthesia care unit and the next day of surgery at the time of post operative surgical visit. Complete Patient Satisfaction Survey at the time of discharge from the Post Anesthesia Care Unit (PACU)

In an aging population, cataract and presbyopia become increasingly common. A cataract is the opacification of the natural crystalline lens inside a person's eye, causing reduction of vision. Presbyopia is an age related condition resulting in loss of reading/near vision which results in requiring reading glasses. Astigmatism is a common condition characterized by an abnormal cornea (the clear tissue at the front of the eye) which results in blurred distance and near vision, again requiring glasses. Cataract surgery is the most common elective surgery worldwide for patients over 65. It is composed of removal the cataract and insertion of a new intraocular lens (IOL). Currently only monofocal IOLs are available on the National Health Service (United Kingdom) - meaning they give good distance or near vision. The majority of patients opt for good distance vision with glasses to read. The investigators are trialling insertion of a new Extended Depth of Focus (enhanced aspheric) Toric IOL (EDoF Toric IOL), which treats all 3 conditions - cataract, presbyopia and astigmatism. All patients attending St Thomas' hospital for treatment of cataracts, who have presbyopia and astigmatism will be considered for invitation to the study. Patients who participate in the study will be randomly selected to receive either the new IOL - the TECNIS Eyhance Toric II IOL, or a well-established IOL the Alcon Acrysof IQ Toric IOL during cataract surgery. Insertion of the Alcon Acrysof IQ Toric IOL is known to treat cataract and astigmatism but not presbyopia. Patients will be assessed and have their surgery performed at St Thomas' Hospital London. They will have 7 appointments over 12 months, plus surgery. The investigators hope to demonstrate better distance, intermediate and near vision and increased spectacle independence in the TECNIS Eyhance Toric II IOL group. EDoF Toric IOLs have the potential to transform cataract surgery outcomes for patients in the NHS.

The Congenital Muscle Disease Patient and Proxy Reported Outcome Study (CMDPROS) is a longitudinal 10 year study to identify and trend care parameters, adverse events in the congenital muscle diseases using the Congenital Muscle Disease International Registry (CMDIR) to acquire necessary data for adverse event calculations (intake survey and medical records curation). To support this study and become a participant, we ask that you register in the CMDIR. You can do this by visiting www.cmdir.org. There is no travel required. The registry includes affected individuals with congenital muscular dystrophy, congenital myopathy, and congenital myasthenic syndrome and registers through the late onset spectrum for these disease groups. The CMDIR was created to identify the global congenital muscle disease population for the purpose of raising awareness, standards of care, clinical trials and in the future a treatment or cure. Simply put, we will not be successful in finding a treatment or cure unless we know who the affected individuals are, what the diagnosis is and how the disease is affecting the individual. Registering in the CMDIR means that you will enter demographic information and complete an intake survey. We would then ask that you provide records regarding the diagnosis and treatment of CMD, including genetic testing, muscle biopsy, pulmonary function testing, sleep studies, clinic visit notes, and hospital discharge summaries. Study hypothesis: To use patient and proxy reported survey answers and medical reports to build a longitudinal care and outcomes database across the congenital muscle diseases. To generate congenital muscle disease subtype specific adverse event rates and correlate with key care parameters.

Effect of peroral caffeine consumption on the delay of cataract onset.

Cataract patients were implanted with different types of intraocular lenses for grouping. SSOCT scanning was used to measure ELP and optometry.
