Brief summary: This is a single-center, prospective, open-label PMCF study whereby patients undergoing routine cataract surgery will have mono- or bilateral implantation of hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC (study no. PHY2101, ClinicalTrials.gov ID: NCT04744467)

Detailed description: This is a single-center, prospective, open-label PMCF study whereby patients undergoing routine cataract surgery will have mono- or bilateral implantation of 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. 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.

If only one eye qualifies for toric lens implantation due to small amount of pre-existing corneal astigmatism, one eye will be implanted with PODEYE TORIC and the contralateral eye will be received an implantation with the monofocal parent lens PODEYE.

The study purpose is to determine safety, rotational stability, refractive and visual performance, contrast sensitivity, patient satisfaction and PCO rate after mono- or bilateral implantation of PODEYE TORIC intraocular lens.

In total approx. 15 patients will be recruited for this clinical study and undergo mono- or bilateral implantation of PODEYE TORIC intraocular lens. The maximum time between 1st and 2nd eye implantation is 30 days.

Subjects participating in the trial will attend a total of maximum 12 study visits over a period of 330-420 days (preoperative, operative, 1-2 days, 7-14 days, 30-60 days, 120-180 days and 330-420 days postoperative visits). Subjects would have the option for unscheduled visits if required medically.

Eligibility criteria: Inclusion Criteria:

* Male or female adults ages 50 years or older on the day of screening who have clinically documented cataracts in both eyes;
* Calculated IOL power (sphere and cylinder) is within the range of the investigational IOLs;
* Regular corneal astigmatism (measured by a topographer);
* Corneal astigmatism ≥0.75 D and ≤ 4.25 D (measured by an automatic keratometer) in one or both eyes;
* Capability to understand and sign an IRB approved informed consent form and privacy authorization;
* Clear intraocular media other than cataract;
* Dilated pupil size large enough to visualize IOL axis markings postoperatively;
* Best corrected visual acuity projected to be better than 0.2 logMAR after toric IOL implantation;
* Willing and able to conform to the study requirements.

Exclusion Criteria:

* Age of patient \<50 years at the day of screening;
* Regular corneal astigmatism \<0.75 D or \>4.25 D (measured by an automatic keratometer) in both eyes
* Irregular astigmatism (measured by a topographer);
* Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal or optic disorders);
* Subjects with AMD suspicious eyes as determined by OCT examination;
* Previous intraocular or corneal surgery;
* Traumatic cataract;
* History or presence of macular edema;
* Instability of keratometry or biometry measurements; Acceptable maximum standard deviation: AL: ± 150 µm; ACD: ± 150 µm; K1 / K2: ± 0.15 D;
* Clinically significant, uncontrolled glaucoma with expected negative impact on Contrast Sensitivity and/or visual acuity outcomes;
* Pregnant, lactating or, if able to bear children, unwilling to use medically acceptable birth control over the course of the study;
* Concurrent or previous (within 30 days) participation in another drug or device investigation;
* Clinically significant dry eye as determined by the investigator' s judgement;
* Ocular surface disease (clinical symptoms or keratitis);
* Patients showing contraindications as listed in the current Instructions for use (IFU);
* Unsuitable for study participation for any other reason, as determined by Investigator's clinical judgment (reason to be documented on eCRF).

In addition to above mentioned in- and exclusion criteria, subjects shall be discontinued when certain conditions are present at the time of surgery, including:

* zonular instability;
* need for iris manipulation;
* capsular fibrosis or other opacity; and
* inability to fixate IOL in desired position. In such cases, the subject shall be followed until the condition has stabilized.
