One-Year Clinical Outcomes Following Aspheric Toric Monofocal IOL with a Double C-Loop Haptic Design Implantation.

Purpose: This study aimed to evaluate one-year clinical outcomes in cataract patients with pre-existing corneal astigmatism implanted with a biconvex aspheric toric monofocal intraocular lens (IOL) with a double C-loop haptic-design. Methods: One hundred and eighteen patients (236 eyes) with corneal astigmatism (≥0.75D) were implanted bilaterally with the PODEYE toric IOL and assessed up to 1-year after surgery. Postoperative evaluation 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. Results: At the last postoperative visit, 74.6% and 95.8% of eyes were within ±0.50D and ±1.00D of the target refraction, respectively. About 78.0% and 97.5% of eyes showed a postoperative refractive cylinder of ≤0.50D and ≤1.00D, respectively. The mean manifest spherical equivalent value was 0.16±0.40D, and the mean refractive cylinder value was -0.42±0.33D. 97.5% and 100% of patients had a binocular UDVA and CDVA of ≥20/32, respectively. The mean binocular UDVA and CDVA were 0.01±0.09 and -0.03±0.07 logMAR, respectively. Under mesopic conditions, 79.5% and 89.8% of patients showed a binocular UDVA and CDVA of ≥20/32, respectively. The mean binocular UDVA and CDVA were 0.15±0.11 and 0.10±0.10 logMAR, respectively. Binocular contrast sensitivity function both under photopic and mesopic conditions was good. The mean absolute IOL rotation was 2.52±2.59 degrees with 98.56% of eyes having a rotation of less than 10 degrees. Conclusion: Bilateral implantation of an aspheric toric monofocal IOL with a double C-loop haptic design in cataract patients with corneal astigmatism provides good visual and refractive outcomes up to 1-year post-surgery.
