Filter by:Purpose: The aim of this study was to evaluate corneal endothelial cell density and morphology, central corneal thickness, and best visual acuity using US phacoemulsification or Nanosecond laser technique. Setting: Department of ophthalmology, Nabeul, Tunisia. Design: Prospective cohort study. Methods: The study included eyes with nuclear cataract density grade 1, 2, 3, or 4 according to LOCS III, divided into two groups; Group 1 had conventional US, and group 2 had nanosecond laser. The Endothelial Cell Density (ECD), coefficient of variation (CoV) in cell size, percentage of hexagonal cells, central corneal thickness and best visual acuity were evaluated over 24 months.
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 objective is to assess the efficiency of the Active Sentry handpiece at low intraocular pressure (IOP) compared with the Ozil at high IOP.
This study aims to identify if the use of BSS PLUS® Sterile Intraocular Irrigating Solution as an irrigation solution leads to improved corneal outcomes vs BSS® Sterile Irrigating Solution in more compromised corneas.
Cataract surgery is one of the most commonly performed and reliable surgeries among eye diseases. While cataract surgeries were performed under general or local anesthesia in previous years, they are now performed topically. Despite providing conscious sedation with agents such as benzodiazepines and opioids before and during surgery, patients experience pain, anxiety, and discomfort during the surgical procedure. One of the non-pharmacological methods used to relieve acute pain during surgical intervention is stress ball. It is also used to reduce pain and anxiety and increase patient comfort. The stress ball suppresses most of the nerves and muscles directly connected to the brain around the wrist and hand, stimulating nerve and muscle activity. This mechanism reduces the release of stress hormones, regulates blood pressure by providing relaxation and relief, and helps reduce anxiety and acute stress. When literature is examined, it is seen that stress ball application is effective on patients' pain, anxiety, and vital signs; however, no randomized controlled study has been found in which stress ball application was performed during cataract surgery. This study was planned to investigate the effect of stress ball application during cataract surgery on patients' anxiety, pain, and vital signs.
Effectiveness of anterior chamber drainage on the structure of the anterior chamber, the position of the intraocular lens and the shape of the corneal incision in the early stage of cataract surgery with high intraocular pressure
Prospective, randomized, subject/evaluator-masked post market clinical study at up to 2 sites at Gemini eye clinic in Czech Republic. Randomization will be done by the eye surgeon. The purpose of this post market clinical trial is to compare the safety and efficacy of Ophtesis Bio 3% with a similar 3% sodium hyaluronate OVD in routine cataract surgery.
The goal of this observational study is to assess the effect of intraocular lens (IOL) movement in patients who have undergone Clareon® Vivity® IOL implantation. The main question it aims to answer is: Does an association exist between IOL movement and patient quality of vision? Participants implanted with Clareon® Vivity® and Vivity® Toric IOLs will be asked to do the following: - consent to participate in the study - allow researchers to access their personal medical records - undergo a series of tests to assess the position of their IOLs and quality of vision Researchers will compare the patients' preoperative and postoperative test results to determine whether an association exists between IOL movement and patient quality of vision.
A study to assess the safety and efficacy of K-321 in participants with FECD after simultaneous cataract surgery and descemetorhexis.
The investigational devices are approved intraocular lenses (IOLs) intended to be implanted after phacoemulsification in individuals suffering from age-related cataract with the need of cataract surgery. Cataract surgery with precedent bilateral randomized IOL implantation will be performed in subjects who have signed an informed consent form. Postoperative examinations will be implemented in accordance with the approved investigational plan.
