Active clinical trials for "Aphakia"

This study will determine the safety and effectiveness of the Artisan Aphakia Lens when used as a secondary implant to correct aphakia in adults.

The primary objective of this study is to conduct a post-approval study which compares the LAL to a monofocal control IOL for safety outcomes.

The purpose of this study is to determine the safety and effectiveness of the Artisan Aphakia Lens in the treatment of aphakia in children.

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.

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.

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.

The purpose of this Post-Market Clinical Follow-up study is to describe the long-term safety and performance of the Clareon Vivity and Vivity Toric and Clareon PanOptix and PanOptix Toric IOLs.

This study is a prospective, multicenter, randomized, double masked confirmatory trial comparing an investigational trifocal intraocular lens (IOL) and a commercially available monofocal IOL.

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.

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).
