This is a monocentric retrospective, open-label clinical study in patients after unilateral or bilateral implantation of hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC and executed only with standard of care examinations.

The investigational device is CE approved. The investigational device and all study products, including the devices used for the study examinations, have been used within the intended use specifications from the manufacturer. In addition, there were no invasive or other burdening examinations.

The investigator is an accredited and experienced cataract surgeon and researcher.

The primary endpoint is to determine rotational stability in a minimum of 120 eyes of patients with PODEYE TORIC IOL implantation after cataract surgery. Patients will be enrolled for the documentation and evaluation of retrospective data up to 6 months postoperatively.

Age-related changes of the proteins in the crystalline lens lead to cataract formation. Cataracts are a common condition in adults over 40 years of age, and surgical replacement of the cataractous lens with an intraocular lens (IOL) remains an effective way to restore vision to cataract patients.

On patients with a low amount of pre-existing corneal astigmatism (defect in the sphericity of the cornea with a focal point depending on the meridian), the implantation of a spherical monofocal IOL is the state- of- the-art when targeting a good correction of distance visual function. However, in case of pre-existing corneal astigmatism, the implantation of spherical IOLs might not be the best solution, as such lenses only correct for spherical errors and leave the astigmatism uncorrected.

Toric IOLs are obtained by adding a cylinder power to the basis optic of a given spherical power, thus correcting for both spherical and cylindrical refractive errors. Toric IOLs provide the opportunity to reduce or eliminate astigmatism, thus offering patients with pre-existing astigmatism the possibility of restoring their distance vision with reduced or no need for the use of spectacles or contact lenses with a cylindrical correction. Not correcting the astigmatism component at the time of cataract surgery is an important cause for not obtaining planned emmetropia following IOL implantation. A previous study found that more than 22% of patients undergoing cataract surgery have substantial corneal astigmatism superior than 1.25 D and would benefit from toric IOL implantation 1).

This study will add to the knowledge on toric IOLs and help improve the care of patients and the outcomes of cataract surgery after toric IOL implantation.

The study is a monocentric, retrospective study to investigate rotational stability and visual performance after mono- or bilateral implantation of PODEYE TORIC intraocular lens following cataract surgery, executed only with standard of care examinations. The study outcomes will be used to confirm the safety performance for a stable IOL positioning of the investigation al device.

Preoperative, surgical and postoperative data (up to 6 months after surgery) will be collected retrospectively by reviewing the patient charts.

The investigational device PODEYE TORIC IOL is CE approved and commercially available in the country where this clinical investigation is being carried out. The investigational device and all study products, including the devices used for the study examinations, have been used within the intended use specifications from the manufacturer. In addition, no invasive or other burdening examinations will occur for the patient.

Inclusion Criteria:

• Male or female adults aged 35 years or older on the day of treatment that were mono- or bilaterally implanted with PODEYE TORIC intraocular lens
• Capable of understanding the patient informed leaflet;
• Complete data available at the screening visit, surgical visit and at least one postoperative visit.

Exclusion Criteria:

• Age of patient <35 years at the day of surgery;
• Subjects who underwent previous intraocular or corneal surgery other than IO L implantation;
• Subjects in whom in-the-bag implantation was not possible;
• Subjects in whom surgical complications occurred (e.g. posterior rupture);

Adult patients who have undergone cataract surgery with mono- or bilateral implantation of POD EYE TORIC IOL (POD T 49P) and who meet all the inclusion and exclusion criteria will be invited to participate in the study.

Patients will be contacted consecutively and will be enrolled after the patient informed leaflet has been given to them and after obtaining their consent to the scientific use of their data collected retrospectively (preoperative, surgery, postoperative routine visits). Patients will only be enrolled after the routine 4-6 months visit has been performed.
