Filter by:Background of the study: Cataract is widely prevalent in especially elderly and cataract extraction surgery has thus become one of the most performedsurgeries worldwide. In recent decades the safety of cataract surgery has greatly improved and it is considered one of the safestsurgeries to be performed. Postoperative management consists of routine examinations within one week, to ascertain no adverseevents have occurred immediately after surgery, and between 4-6 weeks, to determine the refractive error. The incidence of seriousadverse events following cataract surgery is estimated to be 1%. As a result, the majority of patient visits after cataract surgery willbe uneventful. Nonetheless valuable time and hospital resources are consumed. Remote monitoring could replace clinicalexaminations in selected patient groups. However, this practice of digital remote monitoring which the patient can use independentlyhas not been clinically validated yet. Objective of the study: To determine non-inferiority of the corrected distance visual acuity (CDVA) with the prescription obtained through the web-basedmeasurement of refractive error, compared to usual care, in patients who underwent routine cataract surgery. Study design: Observational randomized trial without interventions Study population: Patients eligible for cataract surgery, without visual acuity influencing comorbidities or predisposing complicating factors. Primary study parameters/outcome of the study: costeffectiveness Secundary study parameters/outcome of the study (if applicable): Corrected distance visual acuity at the final post-operative visit, uncorrected distance visual acuity, refractive error(sphere/cylinder/axes), patient reported outcome measurements, adverse events.
Lens capsular often changes after pediatric cataract surgery，causing complications such as anterior capsulerhexis shrinkage, visual axis opacification (VAO), zonular dehiscence and so on. The aim of study was to prospectively investigate the capsular outcomes of pediatric cataract surgery with primary intraocular lens (IOL) implantation.
The study objective is to evaluate the visual performance of MINI WELL Ready at 24 months following the second eye implant. The objectives of safety are to evaluate the rate of Secondary Surgical Interventions related to the optical properties of the IOL for first and second operative eye separately at 24 months and the rate of visual disturbances and distortions as reported by the subjects as detected by using the Halo & Glare Simulator.

To evaluate the refractive outcomes of cataract surgery in PEX syndrome and determine which of the commonly used IOL formulas (SRK/T, Barrett Universal II and Hill-RBF) is the best in predicting postoperative refractive outcomes in PEX.
Cataract surgery is the most common surgical procedure performed on humans today. The postoperative regimen includes a combination of steroids, NSAIDs (non-steroidal anti-inflammatory drugs) and antibiotics. Those are used to decrease the possibility of infection, inflammation that may lead to corneal and macular edema and pain management. There are several FDA approved agents either for topical use as single drug delivery or combination solutions for topical use as well; furthermore, there are slow release vehicles that may be placed at the time of surgery or postoperatively (at the lower punctum). The latter provides a less intense and demanding drop schedule and may improve patient compliance.
Most patients treated for cataract surgery benefit from a short outpatient course with topical local anesthesia. Having to undergo surgery, especially on the eye, without being asleep, can be stressful. Sometimes waiting in a waiting room with other patients can increase this stress. Patient anxiety may increase blood pressure potentially leading to the prescription of nicardipine to allow surgery to be performed. The patient's anxiety also increases the surgeon's stress, which can alter the conditions for performing the intervention and increase the risk of intraoperative complications. Besides the administration of anxiolytics, nurses have few options for patients with anxiety. However, the treatment response time is not always appropriate and the patient's cooperation during the procedure can sometimes be impaired. The effect of music on preoperative anxiety has been evaluated in several studies and has shown a significant decrease in anxiety before surgery. MusicCare® is a "digital treatment" based on the principles of hypnoanalgesia which has been tested in the management of patients with various pathologies (depression, Alzheimer's disease, chronic pain, etc.) and has shown relative effectiveness. the absence of intervention on the pain and anxiety of patients. In the context of cataract surgery with topical local anesthesia, we would like to assess the contribution of offering the MusicCare® listening device on patients' anxiety about absence
This is a single-center, prospective, open-label PMCF study whereby patients undergoing routine cataract surgery will have mono- or bilateral implantation of hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC (study no. PHY2102)
