Filter by:Background: Paticipants undergoing cataract surgery find postoperative medication management difficult and are anxious about this issue. Differences in the number of medications and frequency of administration can be lead to confusion in participants. Aims and objectives: The aim of this randomized-controlled study was to evaluate the effect of using SMS, which reminds about the intake of medication, on reducing postoperative anxiety in participants undergoing cataract surgery. Design: Randomized controlled study.
To assess the rotation stability of toric intraocular lenses between sitting or routine settings (sitting, going around) after cataract operation.
The investigational device is an approved femtosecond laser (FSL) device with an integrated imaging system to perform certain steps of the cataract procedure. The FSL will perform anterior capsulotomy and lens fragmentation in individuals suffering from age-related cataract with need of cataract surgery. The laser will be reduced to image the Berger space. If not visible, the space will be enhanced with BSS and Volon A to visualize the BS. Cataract surgery will be performed in subjects who have signed an informed consent form. Macula thickness will be measured with Spectralis OCT on screening date. Postoperative examinations will be implemented in accordance with the approved investigational plan on subjects and includes: visual acuity, slitlamp examination and retinal oct imaging.
The aim of this prospective study was to investigate whether non-fasting recommendation could reduce preoperative anxiety level, incidence of anesthetist interventions, and number of surgical complications in elective cataract surgery patients.
Monocentric clinical study to develop an imaging analysis algorithm for the Eyestar 900 to identify keratoconus corneas and improve biometry for intraocular lens calculations
The objectives of the study is to evaluate efficacy and long-term safety of the Lucidis lens. Through this study, the objective is to obtain an up-to-date clinical evaluation of the medical device thus supplementing data from experimental trials. Clinical and functional changes in the implanted eyes among a patient population in which the opaque crystalline lens resulting from cataract was removed and replaced by a Lucidis IOL will be described.
Early cataract surgery in microcornea/microphthalmia eyes is essential to prevent amblyopia and improve visual outcomes, including stereopsis. However, despite recent advances in pediatric cataract microsurgical techniques, this surgery remains challenging owing to several intraoperative difficulties attributable to the crowded anterior segment in these small, soft, and poorly developed eyes with shallow anterior chambers, and poor pupillary dilation. In this study the investigator aim to report on the changes in the anterior segment biometric characteristics after cataract extraction in eyes with microcornea/microphthalmia with congenital cataract.
The Objective Visual Quality Analysis System (OQAS) is a new inspection technology used to objectively assess the visual quality of the human eye. The investigators use this advanced technology to evaluate and follow up cataract patients before and after surgery, and observe the incidence, severity, and treatment effects of postoperative complications such as postoperative complications, and analyze the severity and artificial The influence of lens type, postoperative time, systemic diseases and other factors on the effect of cataract surgery, in order to discover the key factors that affect the effect of cataract surgery and the management of complications, and provide a useful reference for improving the level of cataract prevention and treatment in China
This is a clinical trial comparing an investigative accommodative IOL and two commercial IOLs in patients with cataracts undergoing primary cataract surgery.
The purpose of this research study is to evaluate the clinical outcomes of the use of low-energy segment removal with a micro-interventional irrigation/aspiration port (MICOR-304) to evacuate the lens prior to intraocular lens insertion in subjects undergoing routine cataract surgery.
