Clinical performance of a hydrophobic acrylic toric intraocular lens with a double C-loop haptics in Japanese patients

Purpose To evaluate the clinical performance of a hydrophobic acrylic toric intraocular lens (IOL) with double C-loop haptics in a Japanese population with cataracts. Study design Prospective Methods The PODEYE TORIC IOL (POD T 49P) was implanted in 58 eyes from 42 patients diagnosed with bilateral cataracts with corneal astigmatism. Thirty-one eyes received IOLs with cylinder powers of 1.50 to 6.00 D (group A), and 27 eyes received IOLs with 1.00 D cylinder (group B). Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, and refractive cylinder were examined postoperatively. The primary endpoints, which were the non-inferiority of UDVA in group A and superiority of the refractive cylinder in group B, were examined and compared with relevant previous data. Results In group A, the mean preoperative corneal astigmatism was 1.87±1.01 D and postoperative logMAR UDVA and CDVA were -0.023±0.110 and -0.102±0.079, respectively. There were 23 eyes (74.2%) with UDVA of 0.0 logMAR or better, while the refractive cylinder was - 0.39±0.39 D. In group B, the preoperative corneal astigmatism of 0.73±0.22 D and postoperative logMAR UDVA and CDVA were -0.074±0.091 and -0.096±0.075, respectively; 23 eyes (85.2%) obtained a UDVA of 0.0 logMAR or better. The postoperative refractive cylinder was -0.16±0.23D. The non-inferiority of UDVA in group A and the superiority of the refractive cylinder in group B were verified with previous data. Conclusion The PODEYE TORIC IOL with 1.00–6.00 D cylinder powers and double C-loop haptics effectively corrected corneal astigmatism in Japanese patients after cataract surgery.
