Using a new device to prevent complications in cataract surgery

Influence of CleaRing Open-capsule Device on Refractive Predictability in Cataract Patients (Part 2)

Not applicable Interventional Hanita Lenses · NCT06083025

This study is testing a new device to see if it can help prevent complications after cataract surgery for patients getting the procedure on both eyes.

What this trial studies

This clinical trial evaluates the effectiveness of the Hanita CleaRing device, an intraocular implant designed to inhibit posterior capsule opacification (PCO) in patients undergoing cataract surgery. The device is implanted into the capsular bag after the removal of the crystalline lens and before the insertion of the intraocular lens (IOL). By preventing PCO, the study aims to reduce the need for Nd:YAG laser treatment, which can have complications and economic implications. The trial focuses on patients who are candidates for bilateral cataract surgery and assesses the device's impact on visual outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50 to 80 who are scheduled for bilateral cataract surgery and meet specific ocular criteria.

Not a fit: Patients with glaucoma, previous intraocular surgery, or certain corneal abnormalities may not benefit from this study.

Why it matters

Potential benefit: If successful, this device could significantly reduce the incidence of PCO and improve visual outcomes for cataract surgery patients.

How similar studies have performed: Previous studies have shown varying success with different approaches to preventing PCO, but the use of the CleaRing device represents a novel approach.

Inclusion Criteria:

* Subject is between 50 and 80 years of age
* Subject is designated for bilateral cataract surgery
* Both eyes fulfil the following criteria:

  * Potentially able to achieve a good vision (by opinion of the investigator)
