Brief 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).
Detailed 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.
Interventions
DEVICEPOD 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Uncorrected visual acuity at Visit 4 | Postoperative Day 120-180 | Uncorrected visual acuity at 5 m will be measured. Convert decimal visual acuity to logMAR value using the following formula. logMAR value = log10 (1/decimal visual acuity) |
| Amount of astigmatism at Visit 4 | Postoperative Day 120-180 | Manifest cylindrical refraction for Best Collected Distance Visual Acuity will be measured at Visit 4. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Best Corrected Distance Visual Acuity | Pre-Op, 1 week postoperative, 1 month postoperative, 6 months postoperative. | Best Corrected Distance Visual Acuity at 5 m will be measured. The objective is to compare CDVA above defined thresholds of the investigational product. |
| Manifest cylindrical refraction | Pre-Op, 1 month postoperative, 6 months postoperative | Manifest cylindrical refraction for Best Collected Distance Visual Acuity will be measured. |
| IOL rotation | Pre-Op, 1 month postoperative, 6 months postoperative | After mydriasis, a photograph of the anterior segment of the test lens is taken using an anterior segment analyzer, and the angle of the toric mark with respect to the horizon is measured as the axial angle. Calculate the number of the eye and the percentage of less than 5 degrees, more than 5 degrees to less than 10 degrees, more than 10 degrees to less than 20 degrees. |

| Slitlamp examination - IOL decentration | 1 day postoperative, 1 week postoperative, 1 month postoperative, 6 months postoperative, 12 months postoperative, 24 months postoperative | The slitlamp examination is one examination to analyse the integrity of eye structures and the implanted IOL. The examination is performed and documented according to the guidelines in ISO 11979-7:2018. With the slitlamp the ophthalmologist can observe the eyes stereoscopically. A focussed slit of light, which can be width-adjusted, is projected on the eye to be examined. The investigator observes this projection on the eye through a reflected light microscope. The slitlamp is used to observe the anterior and posterior part of the eye, including cornea, lens and anterior chamber. By dilating the pupil the fundus can also be examined.
