Measurements included monocular and binocular uncorrected-distance visual acuity (UDVA) and corrected-distance visual acuity (CDVA), under both photopic and mesopic lighting conditions. Refraction, photopic and mesopic contrast sensitivity (with and without glare), and rotational stability were also recorded at the last postoperative visit.Results: At 4– 6 months, 78.2% and 98.9% of eyes were within ± 0.50D and ± 1.00D of the target refraction, respectively. The mean spherical equivalent and refractive cylinder values were 0.09± 0.35D and − 0.36± 0.35D, respectively. 76.5% and 98.8% of eyes presented a postoperative refractive cylinder of ≤ 0.50D and ≤ 1.00D, respectively. 91.5% and 100% of patients had a binocular UDVA and CDVA of ≥ 20/25, respectively. The mean binocular UDVA and CDVA were 0.02± 0.08 and − 0.02± 0.07 logMAR, respectively. Under mesopic conditions, 78.7% and 83.0% of patients presented a binocular UDVA and CDVA ≥ 20/32, respectively. The mean binocular UDVA and CDVA were 0.15± 0.11 and 0.12± 0.11 logMAR, respectively. The patients showed good contrast sensitivity under photopic and mesopic conditions. The mean absolute IOL rotation was 1.22± 2.21 degrees with 97.87% of eyes having a rotation of < 10 degrees.Conclusion: This study shows good visual and refractive outcomes for the PODEYE toric IOL when implanted bilaterally in cataract patients with corneal astigmatism.Keywords: monofocal toric, astigmatism, double C-loop, intraocular lens, cataract
