REFRACTIVE CATARACT SURGERY WITH A NEW TORIC INTRAOCULAR LENS WITH AN ENHANCED OPTICAL PROFILE AND MODIFIED HAPTICS

To present clinical data on residual refractive astigmatism, visual acuity (UDVA, CDVA) and toric alignment of the Tecnis Eyhance Toric II intraocular lens IOL (J&J Vision) after implantation in cataract surgery

67 eyes were implanted with a Tecnis Eyhance Toric II IOL with different cylinder powers at the IOL plane (DIU100 n=10, DIU150 n=22, DIU225 n=14, DIU300 n=7, DIU375 n=4, DIU450 n= 4, DIU525 n=6). Outcome measures included residual refractive astigmatism, (un-)corrected distance visual acuity and toric IOL alignment

At 30-90 days postoperatively, the residual refractive cylinder was -0.30 ± 0.33 (DIU100), -0.33 ± 0.30 (DIU150), -0.29 ± 0.26 (DIU225), -0.58 ± 0.29 (DIU300), -0.50 ± 0.46 (DIU375), -0.75 ± 0.20 (DIU450), -0.46 ± 0.33 (DIU525) and -0.42 ± 0.39 (DIU groups combined). UDVA was -0.12 ± 0.13 (logmar) and DCVA was -0.02 ± 0.08 for the DIU groups combined. Degree misalignment was 0.8 ± 1.8 (DIU100), 0.6 ± 1.2 (DIU150), 1.1 ± 2.2 (DIU225), 0.6 ± 0.8 (DIU300), 1.0 ± 1.0 (DIU375), 2.3 ± 2.9 (DIU450), 2.8 ± 4.3 (DIU525) and 1.0 ± 1.9 (range: 0 – 9) for the DIU groups combined

Implantation of the Tecnis Eyhance Toric II IOL seems to be an effective method for astigmatism correction in cataract patients because of low residual refractive astigmatism and an accurate toric alignment profile of this new lens with modified optical profile.
