Clinical Trial Summary

This is a Multi-center, single-arm and non-masked study whereby patients undergoing routine cataract surgery be implanted with a hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC (model POD T 49P).

Description:

This is a Multi-center, single-arm and non-masked study whereby patients undergoing routine cataract surgery will be implanted with a hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC. The device under investigation is a hydrophobic acrylic monofocal toric intraocular lens (IOL) manufactured by the sponsor of this study (BVI Medical). The refractive power of the lens has a spherical and a cylindrical component. The IOLs will be implanted in the course of routine cataract surgery and will benefit to patients suffering from cataract development and showing pre-existing corneal astigmatism. In total approx. 28 patients, 56 eyes will be recruited for this clinical study and undergo implantation of PODEYE TORIC intraocular lens. Subjects participating in the trial will attend a total of maximum 6 study visits over a period of 120-180 days (preoperative, operative, 1-2 days, 7-14 days, 30-60 days, 120-180 days, postoperative visits). Subjects would have the option for unscheduled visits if required medically.

If the IOL stability would be compromised, the investigational IOL should not be implanted, the subject should be discontinued from the study, and the surgeon should make arrangements to implant an alternative non-investigational IOL.

Intervention

Device:
• POD T 49P implantation experimental
The investigational lens will be implanted within the capsular bag after removal of the natural crystalline lens following phacoemulsification and alignment the toric axis of investigational lens to the intend axis which was calculated by the Toric calculator software. When enroll the test lenses into both eyes, the lens is implanted first to the eye with more advanced cataract. If both eyes have a similar degree of cataract, perform the surgery first for the right eye. The timing of surgery the investigational lens into the fellow eye will be determined after the investigator and the investigator (hereinafter referred to as the investigator) have confirmed the safety of the previously operated eye.
