Active clinical trials for "Aphakia"

This is a retrospective, observational (Registry) study aiming to collect safety and performance data on the use of intraocular lenses (IOLs) manufactured by Teleon Surgical B.V. according to routine practice.

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.

The purpose of this study was to evaluate the safety and effectiveness of the HARMONI® Modular Intraocular Lens System with a toric optic (HMTIOL) in subjects with pre-existing corneal astigmatism in need of cataract surgery.

The purpose of this multi-center clinical trial is to determine the safety and efficacy of the HSO Toric IOLs for the correction of aphakia and reduction of pre-existing refractive astigmatism.

This study is to evaluate the safety and effectiveness of the Bausch & Lomb Akreos TL (thin lens) intraocular lens (IOL) following implantation in adults requiring cataract surgery.

The primary purpose of this study is to evaluate the long-term (3 years) visual acuity and adverse event outcomes for the Clareon® Intraocular Lens (IOL). A comparison to historical safety and performance endpoint (SPE) rates as reported in the European Standard International Organization for Standardization (EN ISO) 11979-7:2014 will be conducted at one year. The secondary purpose of this study is to evaluate the visual acuity outcomes with the Clareon IOL at Years 2 and 3.

The objective of this study is to evaluate, for the visual correction of aphakia, whether the RxSight Light Adjustable Lens (LAL) and Light Delivery Device (LDD) can be used to improve visual outcomes after performing adjustments of the LAL with the LDD. This is an exploratory study. No primary effectiveness endpoints will be identified.

The purpose of this study is to evaluate the effectiveness and safety of the TFNT20 low cylinder power intraocular lens when implanted in the eye to replace the natural lens following cataract removal.

The primary objective of this study is to evaluate the safety and effectiveness of performing 0.50 D cylinder correction on the RxSight Light Adjustable Lens (LAL) in patients who have undergone implantation with the FDA approved, commercially available LAL.

The objectives of the Post-Market Follow-up (PMCF) clinical investigation are to determine the safety and performance of a hydrophobic trifocal intraocular lens POD L GF in comparison with two comparator lenses: another multifocal intraocular lens (Johnson & Johnson TECNIS Symfony® Extended Range of Vision IOL); and a monofocal intraocular lens (Alcon AcrySof® IQ Monofocal IOL) through one year of post-operative assessments.
