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)
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.

Mono- or bilateral implantation of toric intraocular lenses PODEYE TORIC. 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 receive an implantation with the monofocal parent lens PODEYE (PhysIOL sa/nv, Liège, Belgium).

Rotational stability - Photograph of IOL with dilated pupil to asses IOL rotation
The primary performance endpoint is to show statistically non-inferior rotational stability outcomes on PODEYE TORIC lens compared to CER data obtained for a multifocal toric IOL (POD FT) by the same manufacturer sharing the same haptic design but based on a hydrophilic lens material. The null hypothesis is that the absolute mean IOL rotation measured on PODEYE TORIC is not larger than the absolute mean IOL rotation reported in the current CER on POD FT lens. The alternative hypothesis is that the absolute mean IOL rotation measured on PODEYE TORIC is larger than the outcomes reported in the current CER on POD FT lens. The measure is taken at 6 months postoperative visit compared to the measurement performed within 10 minutes after surgery.
Time frame: 6 months postoperative
Best Corrected Distance Visual Acuity compared to historical Data
The objective is to compare CDVA above defined thresholds of the investigational product to the results of historical data of EN ISO 11979-7:2018, Annex E (Table E.3 and E.4). The null hypothesis for the CDVA is that / when the true rate of cases with visual acuity 0.3 logMAR or better is less than or equal to the SPE rate. The alternative hypothesis is that the "success" rate is higher than the SPE rate. If the distance corrected visual acuity is 0.3 logMAR or better in 30 eyes or more (with 36 eyes included), the null hypothesis could be rejected, and the alternative hypothesis could be accepted.
Time frame: Pre-Op, 1 week postoperative, 1 month postoperative, 6 months postoperative, 12 months postoperative
Change in cylindrical Power of the Eye
Change in cylindrical power, defined as the difference between magnitude of preoperative keratometric cylinder and postoperative manifest cylinder is calculated at every Form. The outcomes of this calculation will be stratified per 0.25D step of preoperative keratometric cylinder and descriptive statistics (mean, standard deviation, median, minimum, maximum) will be provided. In addition, the following outcomes will be tabulated (stratified per 0.25D step of preoperative keratometric cylinder): * The proportion that showed a "reduction in cylindrical power of the eye" \<0.50 D * The proportion that showed a "reduction in cylindrical power of the eye" ≥0.50 D * The proportion that showed change in absolute value "reduction in cylindrical power of the eye" ≤ 0.50 D Also, regression analysis will be performed comparing "Reduction in cylindrical power of the eye" (corneal plane) and preoperative keratometric cylinder.
