Filter by:ABSTRACT Objective: The research was conducted as a prospective randomized controlled experimental study to determine the effect of hand massage applied before cataract surgery on anxiety, surgical fear, pain and physiological parameters of patients. Study design: The sample of the study consisted of 60 patients, 30 experimental and 30 control, who had cataract surgery and met the study criteria in Eye Operating Room of a tertiary hospital between 24 December 2020 and 31 May 2021. Ethics committee, institutional permission and participant consent were obtained in this study, and data were collected using the descriptive characteristics form, Physiological Parameters Observation Form (PPOF), VAS-Anxiety, Surgical Fear Scale (SFS), and VAS-Pain scale. In the study, individuals in the experimental group were given hand massage for 10 minutes before cataract surgery. Before and after hand massage, PPOF, VAS-Anxiety and SFS were measured and recorded. In addition, PPOF, VAS-Anxiety and VAS-Pain were measured and recorded again at the postoperative 30th minute. Pearson chi-square, Shapiro Wilk, Levene test, Two-Way Analysis of Variance in Repeated Measurements, Mann-Whitney U test were used in the analysis of the data.
81 eyes of 81 patients undergoing cataract surgery were included in this prospective interventional study. During cataract surgery, intracameral carbachol was applied to 27 eyes, intracameral epinephrine was administered to 20 eyes and 34 eyes were the control group. Macular choroidal thickness measurement was performed before, 1 day, and 1 week after phacoemulsification surgery in all patients using optical coherence tomography.
Purpose of this study was to evaluate the effect of presbyopic correction lens on Humphrey visual field (HVF) testing in patients with 2 models of multifocal intraocular lens (MIOL) both with and without glaucoma. All participants performed HVF testing with presbyopic collection lenses and without presbyopic collection lenses on the same occasion (5-10 minutes between the test). The mean deviation (MD) and pattern standard deviation (PSD) were compared between with and without presbyopic collection lenses, between glaucoma and non-glaucoma and between 2 models of MIOL.
The world health organization declared corona virus disease (COVID19) a pandemic since march 2020. Since then the future landscape of medical practices and procedures is being heavily shaped by the emergence of this pandemic. COVID 19 testing has already standardized within the medical field as doctors wearing scrubs or fitness examination before operation. We are now more than 2 years into COVID-19 pandemic with more than 6 effective vaccines available in the market for public to boost and build up their immunity against the virus. Every 3 to 4 months we hear about a new strain and another wave of the virus attacking the world, therefore healthcare institutions face enormous challenges in balancing patients' needs and simultaneous safety to health care workers. The Indian council of medical research in June 2020 proposed that testing for Covid-19 for asymptomatic patients coming for elective surgeries should be performed for neurosurgery, ear nose, and throat (ENT) surgery, dental procedures, etc. and for non-surgical interventions like bronchoscopy, upper gastrointestinal endoscopy and dialysis. A role of preoperative testing of Covid-19 for every patient is still controversial especially in asymptomatic healthy patients with not known exposure to a COVID positive patient. Most patients attending eye out patient department (EOPD) are aged 65y and older are considered at a higher risk for worse outcome in case of COVID-19 infection. Therefore a rethink of a cataract surgery pathway should include preoperative perioperative and postoperative care in order to maintain safety conditions for patients and for healthcare staff. COVID-19 can infect anyone and result in transmission of infection before the patient become symptomatic or even without ever developing symptoms. Therefore preoperative screening of patients undergoing ophthalmic surgery should be considered.
This project will apply AI technology to meet the gap between increasing demand and limited capacity of high- volume healthcare services. The project will develop evidence that will support the safe deployment of Ufonia's automated telemedicine platform to deliver calls to cataract surgery patients at two large NHS hospital trusts. The proposed study will implement DORA in addition to the current standard of care for a cohort of patients at Imperial College Healthcare Trust and Oxford University Hospitals NHS Foundation Trust. The study will evaluate the agreement of DORA's decision with an expert clinician. In addition it will test the acceptability of the solution for patients and clinicians; the sensitivity and specificity of the system in deciding if a patient requires additional review; and the health economic benefits of the solution to patients (reduced time and travel) and the local healthcare system. If successful, a proposal will be developed to roll the solution out to all patients at each site in anticipation of an application to a late phase award for wider NHS deployment.
The objective is to assess the visual outcomes and quality of vision of patients receiving the AcrySof® Vivity Intraocular lens (IOL), when implanted in eyes with high ocular axial length (≥24.5mm), after uneventful cataract surgery.
Prognostic factors determining visual outcomes in patients with posterior polar cataracts and posterior lenticonus are largely unknown. In this trial, the investigators aimed to evaluate the visual outcomes in patients with posterior polar cataracts and posterior lenticonus and try to find out the factors associated with the visual acuity after surgery. Patients enrolled in this study will be followed for at least 6 months and will have study visits at 1 day, 1 week, 1 month, 3 month, 6 month postoperatively.
Determine the consequences of COVID-19 pandemic on routine targeted surgeries. Five surgical procedures were considered : cataract surgery, hip and knee arthoplasties, coronary revascularisation by angioplasty and definitive cardiac stimulation. The objective of the study is to quantify changes of these procedures in 2020 and in 2021 (up to June) compared to 2019 taking into account their annual evolution and according to the type of operation (primary or reoperation/revision) and emergency status, if applicable.
Evaluation of capsular bag shape changes after plate-haptic intraocular lens implantation by SS-OCT.
I.SPACE® is a hyaluronic acid injectable gel CE (European Conformity) marketed since 2010. It is indicated for use as a surgical aid in ophthalmic anterior segment surgery. The aim is to protect the corneal endothelium and maintains the intraocular space.The product should be instilled in the anterior chamber of the eye and adjusted according to the volume of the aqueous humour. In this study, 80 patients aged from 18 to 84 years' old at inclusion, who have at least one eye with cataract (mild to moderate severity) based on subjective ophthalmic examination by the investigator, who have given his/her informed consent and meet all the eligibility criteria, will be enrolled. Subjects will come to a total of 7 visits over a period of 3 months. Protection of corneal endothelium (Mean percent change of CEC density) after baseline injection will be assessed. Surgeon's satisfaction during cataract surgery, mean change in Intraocular Pressure (IOP), percentage of eyes with IOP spikes ≥ 30mm mmHg, corneal thickness, intraocular inflammation, Mean Snellen monocular Uncorrected Distance Visual Acuities (UCDVA), Best Corrected Distance Visual Acuities (BCDVA) and safety will be also assessed.
