Filter by:The aim of this questionnaire survey is to evaluate the improvement in vision-related quality of life before and after cataract surgery using the National Eye Institute Visual Function Questionnaire 25 and the delay of improvement in the COVID-19 pandemic.
Randomized, controlled treatment with an intracanalicular dexamethasone (0.4mg) insert following cataract surgery with intraocular lens implant (IOL) combined with minimally invasive glaucoma surgery (MIGS), specifically iStent, iStent inject or KDB in patients with primary open angle glaucoma (POAG) or ocular hypertension (OHTN)
The study will be a multicentric, prospective open-label ethics committee approved clinical study to investigate safety, visual outcomes, contrast sensitivity and rotational stability after bilateral implantation of Isatis TF IOL following cataract surgery.
Multifocal IOLs that maintain distance focus and improve near vision have been developed to reduce spectacle dependence.Multifocal IOLs improve patient performance of near-vision tasks, such as reading crafts, hobbies, and social activities to a greater extent than do monofocal IOLs. However, halos and reduced contrast sensitivity have been associated with multifocal IOLs and are common reasons for patient's dissatisfaction.Trifocal technology has been developed to create intermediate focus to overcome these difficulties. Continuous reports of the visual outcomes of the FineVision trifocal IOLs are encouraging.
Patient satisfaction and dry symptoms in patients undergoing routine uncomplicated cataract surgery in NHS patients treated with prophylactic phosphate-free, preservative-free lubricant eye drops (0.3% cross linked sodium hyaluronate, AEONTM Protect Plus and0.15% Sodium Hyalu-ronate with vitamins A and E, AEONTM Repair): A randomized, prospective, controlled study.
This study aims to assess the performance of an ultrasonic system for automatic classification of cataract type and severity, as well as the estimation of the optimal phacoemulsification energy. Ultrasonic signals from the lens will be acquired with the Experimental Medical Device (ESUS) in participants with cataract, and in healthy subjects (control). The proposed technique may represent an important advance in cataract treatment. The quantitative and automatic classification of cataract type and severity, and the estimation of the optimal phacoemulsification energy is may represent a valuable tool for surgical planning, reducing complications associated to excessive levels of phacoemulsification energy, as well as the times spent on surgeries. This device may be relevant not only for patients, but also for public health systems, reducing waiting lists and associated costs.
To investigate the clinical outcome of Lipiflow treatment prior to cataract surgery in patients with meibomian gland dysfunction and dry eye disease
TCC-PASTE is a randomised controlled trial comparing a simulation based training curriculum with standard training for ophthalmology residents learning to perform tunnel construction in manual small incision cataract surgery. After obtaining informed consent, participating trainees will be randomly assigned to learn to perform tunnel construction either through the simulation based curriculum or through the standard curriculum at their institute. Trainees assigned to simulation will learn through studying an eBook, participating in training sessions supported by repeated practice on a virtual reality simulator, and supervised training in live surgery to facilitate transfer of skill acquired in simulation to the operating room. To determine the effect of simulation based training, we will assess the number of errors trainees perform in the initial part of their intraoperative learning curve.
Cataract patients were implanted with different types of intraocular lenses for grouping. SSOCT scanning was used to measure ELP and optometry.
The purpose of prospective cohort study is to estimate the rate of change in postoperative change after primary IOL implantation among children with congenital cataract(CC) and to explore key factors associated with the rate of change.
