Filter by:To observe the effects of vitreous cavity Balanced salt solution (BSS) tamponade on the state of the lens and related parameters of the eye, and whether the changes of the above parameters are correlated with age, gender, diabetes or not, etc., so as to provide references for the diagnosis and treatment of related diseases and scientific research.
To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs in patients scheduled for bilateral cataract surgery.
This clinical study will assess the safety and performance of Intensity SL IOL, 1 year post operation. The study will also evaluate the patient satisfaction of the implanted patients.
This is a Prospective, single-center, randomized, controlled, paired-eye, single-masked clinical investigation to compare the efficacy and safety of FIDIAL PLUS (bacterial derived 1.8% sodium hyaluronate OVD) and IAL®-F (comparable animal derived 1.8% sodium hyaluronate OVD) while used during phacoemulsification cataract surgery.
Retrospective collection of data from medical records, multicenter, post-market clinical follow-up study.
The aim of this study is to compare Mydrane ®, mydriatic eye drops and Mydriasert ® in terms of pupil site stability, surgical time, visual field and anterior chamber configuration modifications among primary open angle glaucoma (POAG) patients during cataract extraction surgery.
Misalignment of IOLs can cause severe loss of visual quality. Different types of misalignment are known. Tilt is one type of misalignment that is thought to play a negative role for the optical performance in eyes with IOL designs, especially, if they have aspheric, toric or multifocal optics. Due to the fact that tilt has an influence on visual quality, the prediction of the post-operative tilt could improve IOL power calculaton significantly especially for toric IOLs. the Aim of this study is to measure tilt with two modern OCT based devices and one Scheimpflug camera and to predict the post-operative tilt using partial least squares regression.
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.
The objective is to assess the efficiency of the Active Sentry handpiece at low intraocular pressure (IOP) compared with the Ozil at high IOP.
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.
