Clinical Outcomes of an New EDOF IOL (Isopure®)

Cataract Clinical Trial

Official title: Visual Outcomes and Patient Satisfaction After the Implantation of Isopure Extended-Depth-of-Focus Intraocular Lens (EDOF-IOL), With a Mini-Monovision Target

Status Completed

Clinical Trial Summary

Single-center, retrospective, open-label observational study aiming to evaluate visual outcomes and patient satisfaction after bilateral implantation of Isopure® EDOF-IOL with a mono-minovision target.

Clinical Trial Description

This single-center retrospective study investigates visual outcomes and patient satisfaction in subjects bilaterally implanted with Enhanced-Depth of Focus (EDOF) Isopure® IOL during routine bilateral cataract surgery.

The study is carried out in an ophthalmic clinic in Switzerland. In this study, routine surgical techniques and postoperative follow-up will be applied as for all other (non-study) cataract patients in the clinic. Therefore, all study patients will be operated in immediate consecutive bilateral mode (routine in clinic). Patients participating in this study will be recruited and enrolled postoperatively. They undergo routine postoperative follow-up examinations, and data are collected at the third scheduled examination (4 to 6 weeks after surgery) and at a telephone call 4 to 6 months after surgery.

Isopure 1.2.3 is a CE certified intraocular lens readily available on the market in Switzerland.

The primary outcome consists in demonstrating a preserved distance visual acuity while improving binocular spectacle-free intermediate vision and, to a lesser extent, near vision. Binocular defocus curves are measured for each participant to simulate visual acuity at different distances. Patient satisfaction with treatment and subjective ratings of visual phenomena will be assessed using a modified PRISQ questionnaire and a modified NEI quality of vision questionnaire (RQL-42) at the third postoperative visit and three months after surgery.

At Vista Alpina Eye Clinic, mini-monovision is routinely used to further improve binocular intermediate and near vision while preserving the quality of distance vision in patients implanted bilaterally with EDOF Isopure® IOLs. Analysis of the retrospective data should help support this surgical strategy.

Patients with astigmatism up to 1.5 D benefit intraoperatively from Opposite Clear Corneal Incisions (OCCI) to reduce astigmatism. Analysis of our retrospective data will allow comparison of their visual performance with that of patients without astigmatism who did not require an additional OCCI procedure. ;
