Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study population includes subjects who would benefit from the implantation of an intraocular lens (IOL) and are not suitable for a posterior chamber IOL because of insufficient capsular and zonular support.

The LensOne is a sterile, non-optical ocular implant that is permanently inserted into the
posterior chamber of the eye during intraocular surgery. The device is intended to provide stable support for a posterior chamber intraocular lens in eyes that lack capsular and zonular support.
LensOne is suspended in the eye by three fixation arms which are trans-scleraly and subconjunctivally anchored. It has an internal cavity called the IOL housing designed to interact with the haptics of an IOL and securely envelope the IOL.

The LensOne device will be implanted during day surgery by a vitreoretinal surgeon after a screening visit. The surgery is expected to take approximately one hour and participants will be assessed post-operatively at 6 visits over 12 months.

Statistical methods / analysis
All statistical analyses of safety and performance measures will be descriptive in nature. Continuous variables will be summarized by a mean, standard deviation, minimum, median and maximum, and categorical variables by a count and percentage. Confidence intervals (CIs) will be provided where relevant.
No formal sample size calculation has been performed, and the sample size is empirical. However, the sample size of 35 subjects is considered sufficient to adequately characterize the general safety profile and performance of LensOne device.

Summary
Brief summary
The purpose of the study is to demonstrate the safety and efficacy of the LensOne device, which allows surgeons to implant a single piece, posterior chamber IOL in patients with aphakia.
It is hypothesized that the LensOne device can provide surgeons and patients a safe and stable solution for fixating a posterior chamber IOL when there is insufficient capsular and zonular support.
This study aims to establish the safety of the LensOne device and to provide surgeons with a consensus method of securing a posterior chamber IOl when there is insufficient capsular or zonular support.
