Bicentric Clinical Investigation to Assess Safety and Performance of LuxBoost IOL

LuxBoost
Start date: April 15, 2024
Phase: N/A
Study type: Interventional

The study purpose is to demonstrate safety and performance of bilateral implantation of LuxBoost intraocular lenses compared with the LuxGood Monofocal lens.

NCT ID: NCT06166901 Not yet recruiting - Presbyopia Clinical Trials

Evaluation of Long-term Safety and Performance of PanOptix Intraocular Lens (IOLs)

Start date: June 2024
Phase: N/A
Study type: Interventional

The purpose of this Post-Market Clinical Follow-up (PMCF) study is to describe the long-term safety and performance of the AcrySof PanOptix Trifocal toric and non-toric IOL models in subjects bilaterally implanted with these IOLs for 3 to 5 years. This study will be conducted in Spain.

NCT ID: NCT06102109 Recruiting - IOL Opacification Clinical Trials

Long-term Results of Two Surgical Methods for Scleral IOL Implantation and Fixation in Eyes Without Capsular Support: Yamane- Versus 4-flanged Technique

YAMPOINT
Start date: September 19, 2023
Phase: N/A
Study type: Interventional

This study is a comparison of the surgical techniques and postoperative outcome between the two intrascleral IOL fixation techniques: Yamane technique versus the 4-flanged technique. The main objectives are postoperative lens tilt, duration of surgery, intra- and postoperative complication rates and scleral integrity around the flanges.

NCT ID: NCT06065072 Recruiting - Cataract Clinical Trials

Comparative Study of the Tomey OA-2000, Tomey CASIA2, and the LenStar LS900

Start date: June 23, 2023
Phase:
Study type: Observational

This is a prospective comparative study that will be conducted at one clinical site in the United States, in which subjects who sign an informed consent form and fulfil all inclusion and exclusion criteria, will have OCT scans obtained using the test and the predicate devices. There will be two main types of analyses performed as part of this study, including 1) a precision analysis, and 2) an agreement analysis. The precision analyses will be conducted utilizing all complete complements of acceptable scans from the test devices and predicate device for each of the 3 configurations. A complete complement of acceptable scans can be defined as subjects having 3 acceptable replicate scans on each of the 3 devices, at each of the 3 configurations. This is also synonymous with 3 scans for each of the 3 configurations on all 3 devices. If subjects have more than 3 acceptable scans per configuration on a device, only the first 3 will be considered for analyses. The agreement analysis will be conducted utilizing the first set of acceptable scans from each instrument for all overlapping measurement types (for all measurement types two or more of the devices have in common) related to performance endpoints.

NCT ID: NCT05912829 Recruiting - Aphakia Clinical Trials

Comparison of Two Different Intraocular Lenses Implanted With Yamane Technique

Start date: June 1, 2023
Phase:
Study type: Observational [Patient Registry]

In case of instability or rupture of capsular bag occurs during cataract surgery, Yamane technique is one of the options to fix intracocularlens' haptics. Yamane technique uses a double-needle technique that seamlessly fixes the haptics intrascleral by creating a scleral tunnel. Aberrations, IOL tilting or even dislocations might occur and influence the final outcome of IOL implantation. The aim of this study is the evaluation of the postoperative tilt of Kowa PU6AS using Yamane technique. Furthermore of the corrected and uncorrected visual acuity and the anterior chamber depth are being developed.

NCT ID: NCT05852470 Completed - Aphakia Clinical Trials

Evaluation of Clareon Vivity/Vivity Toric

Start date: May 23, 2023
Phase: N/A
Study type: Interventional

This study seeks to generate clinical data from subjects previously implanted with the Clareon Vivity/Clareon Vivity Toric IOLs or Clareon Monofocal/Clareon Toric IOLs. This study will assess key performance endpoints to support clinical benefits with model-specific data.

NCT ID: NCT05829122 Recruiting - Aphakia Clinical Trials

Sutureless Intrascleral Intraocular Lens Fixation and Modified Iris Cerclage Pupilloplasty

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

In this study, patients with various causes of pupillary dilatation were recruited, and medical records and ophthalmology examinations, including slit-lamp examination, visual acuity, best corrected visual acuity, intraocular pressure, pupil diameter, corneal endothelial cell count, fundus examination, and photophobia score, were collected. Those who met the recruitment criteria underwent modified iris cerclage pupilloplasty. The modified iris cerclage pupilloplasty was performed by making four clear corneal incisions, suturing the iris 3-4 times consecutively between each two incisions, completing 360 degrees of iris suturing in sequence, and finally tying the knot intraocularly to complete the iris cerclage.

NCT ID: NCT05821101 Recruiting - Clinical trials for Aphakia, Postcataract

Clinical Outcomes of Clareon Vivity Intraocular Lens With Mini-Monovision Approach

Start date: April 6, 2023
Phase: N/A
Study type: Interventional

Purpose is to study the clinical outcomes of Clareon Vivity and Clareon Vivity Toric intraocular lens (IOL) implants in patients who are planning to have cataract surgery in both eyes with a mini-monovision approach.

NCT ID: NCT05799950 Enrolling by invitation - Aphakia Clinical Trials

A Real-World Evidence (RWE) Long-Term Follow-Up Study to Assess Outcomes of Alcon Monofocal Intraocular Lenses

Start date: August 28, 2023
Phase:
Study type: Observational

The purpose of this post-market clinical follow-up (PMCF) study is to describe the long-term safety and performance of AcrySof Single-Piece and AcrySof Multi-Piece monofocal intraocular lenses (IOLs).
