The purpose of this study is to evaluate the safety and effectiveness of Clareon™ PanOptix™ Pro Trifocal Intraocular Lens (IOL) compared to Clareon™ PanOptix™ Trifocal IOL.
Comparison of safety and efficacy of two scleral fixation intraocular lens (IOL) methods of four-point scleral fixation ( Akreos AO60) and the Yamane technique (AcrySof MA60AC)
The study aims to describe a new method of sulcus fixation of intraocular lenses (IOLs) using a prolene mesh and to compare its outcomes with Yamani technique.
The purpose of this post-market study is to describe the long-term safety and performance of Clareon Toric Intraocular Lenses (IOLs).
The study purpose is to demonstrate safety and performance of bilateral implantation of LuxBoost intraocular lenses compared with the LuxGood Monofocal lens.
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.
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.
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.
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.
