Filter by:Prospective, non-comparative, multicenter study on medical device with 12 months follow-up.
The primary study objective is to compare the effectiveness of the combination of phacoemulsification with intraocular lens implant with ELIOS or iStent inject W in reducing IOP at 12 months postoperatively.
Our study aims to determine the efficacy and safety of the monofocal plate haptic intraocular lens to be implanted in patients planning for cataract surgery and to determine the complications that may develop due to the lens.
The goal of this observational study is to learn about the verification of the effectiveness and visual acuity of LUMINA in patients after lens replacement due to cataracts. The main questions it aims to answer are: - Evaluation of the effectiveness of the LUMINA lens in patients after lens replacement due to cataracts - Evaluation of the accommodative power of the LUMINA lens. Participants will have cataract surgery and the IOL LUMINA will be implanted in the sulcus.
The goal of this Randomized Controlled Trial is to evaluate heart rate variability (HRV)before and after listening to music in patients scheduled for cataract surgery under topical anesthesia, compared to patients who do not listen to music. Our hypothesis is that the anxious population with a low HRV benefits from an anxiolytic effect of music to increase HRV levels.
The goal of this observational study is to assess the clinical outcomes of binocular implantation of Asqelio EDOF Toric IOLs in healthy cataract patients. The main questions it aims to answer are: - What is the visual performance at different distances 3 months after implantation of Asqelio EDOF Toric in both eyes? - What is the amount of residual refractive error following the implantation? - What is the contrast sensitivity of patients 3 months after implantation of Asqelio EDOF Toric in both eyes? - What is the optical quality of the eye implanted with Asqelio EDOF Toric IOL? - What is the incidence and severity of visual symptoms after implantation of Asqelio EDOF Toric? - What is the level of patient satisfaction after implantation of Asqelio EDOF Toric? For this purpose, participants will be submitted to a comprehensive visual and refractive assessment, following common clinical practice, 3 months after binocular implantation of Asqelio EDOF Toric IOLs, and asked to complete visual symptoms and patient satisfaction questionnaires.
The researchers have used the ophthalmology textbook, clinical guideline consensus, the Internet conversation data and knowledge base of Zhongshan Ophthalmology Center in the early stage, combined with artificial feedback reinforcement learning and other techniques to fine-tune and train the LLM, and developed "Digital Twin Patient", a localized large language model that has the ability to answer ophthalmology-related medical questions, and also constructed a combination of automated model evaluation and manual evaluation by medical experts. The evaluation system combining automated model evaluation and manual evaluation by medical experts was constructed at the same time. This project intends to integrate "Digital Twin Patient" into undergraduate ophthalmology apprenticeship, simulate the consultation process of real patients through the online interaction between students and "Digital Twin Patient", explore the effect of "Digital Twin Patient" consultation teaching, provide emerging technology tools for guiding medical students to actively learn a variety of ophthalmology cases, cultivate clinical thinking, and provide the possibility of creating a new mode of intelligent teaching.
The purpose of this study is to evaluate the visual outcomes of the Symfony lens and the Vivity lens under mesopic lighting conditions in adult patients undergoing routine cataract surgery. Participants will be asked to read a visual acuity chart at different distances in dim light.
Phacoemulsification is the most common treatment for cataract surgery in the developed countries and over the years it gained importance due to several factors: small incision, surgery performed under topical anesthesia - which reduce injection-related complications - short recovery time, low post operatory induced astigmatism, and low incidence of surgical complications, when compared to the conventional surgeries. The study evaluates 2 different phacoemulsification devices in patients undergoing routine cataract surgery in both eyes.
Cataract is characterized by the loss of the normal transparency of the crystalline lens. It is a progressive, chronic disease that affect individuals over the age of 50. It is the leading cause of blindness around the world. The EyenableTM IOL (PA60AS1) is a CE-marked foldable single-piece ultra-violet absorbing posterior chamber intraocular lens (IOL). It is an optical implant to replace the human crystalline lens in the visual correction of aphakia in adult patients after cataract removal. This post-market clinical study will investigate the implantation safety and performance of the EyenableTM PA60AS1 intraocular lens (IOL) up to 6 month after the surgery.
