NCT ID: NCT04778098 Completed - Cataract Clinical Trials

Effect of Short Message Service Use on Anxiety

Start date: July 3, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04776057 Recruiting - Astigmatism Clinical Trials

Rotation Stability of Toric Intraocularlens (IOL) Compared Sitting Against Lying After Cataract Operation

Start date: February 1, 2021
Phase: N/A
Study type: Interventional

To assess the rotation stability of toric intraocular lenses between sitting or routine settings (sitting, going around) after cataract operation.

NCT ID: NCT04775849 Recruiting - Cataract Clinical Trials

Intraoperative Berger Space Imaging (IBSI)

IBSI
Start date: May 20, 2019
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04769856 Completed - Cataract Surgery Clinical Trials

Impact of Non-fasting on Anxiety in Cataract Surgery

StarvAnx
Start date: May 2, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04763785 Active, not recruiting - Cataract Clinical Trials

Development of a Keratoconus Detection Algorithm by Deep Learning Analysis and Its Validation on Eyestar Images

DKDA
Start date: May 11, 2021
Phase:
Study type: Observational

Monocentric clinical study to develop an imaging analysis algorithm for the Eyestar 900 to identify keratoconus corneas and improve biometry for intraocular lens calculations

NCT ID: NCT04761276 Recruiting - Cataract Clinical Trials

Evaluation of Efficacy and Long-term Safety for Lucidis Instant Focus© - PMCF Study Protocol

Start date: May 21, 2021
Phase:
Study type: Observational

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.

NCT ID: NCT04759560 Recruiting - Congenital Cataract Clinical Trials

Biometric Characteristics of the Eye With Microcornea/Microphthalmia and Congenital Cataract Before And After Cataract Extraction

Start date: July 25, 2020
Phase:
Study type: Observational

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.

NCT ID: NCT04757350 Recruiting - Cataract Clinical Trials

Objective Visual Quality Analysis System is Used in Cataract

Start date: February 1, 2021
Phase:
Study type: Observational

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

NCT ID: NCT04756908 Recruiting - Cataract Clinical Trials

Safety and Effectiveness of the Opira AIOL in Comparison to Commercial IOLs in Patients Undergoing Cataract Surgery

Start date: October 8, 2020
Phase: N/A
Study type: Interventional

This is a clinical trial comparing an investigative accommodative IOL and two commercial IOLs in patients with cataracts undergoing primary cataract surgery.

NCT ID: NCT04747834 Completed - Cataract Clinical Trials

Assessment of Low Energy Lens Fragmentation Cataract Extraction in Patients Undergoing Cataract Surgery

Start date: January 6, 2021
Phase: N/A
Study type: Interventional

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.
