Visual Outcomes And Rotational Stability Of An Extended Depth-Of-Focus (Edof) Using A Wavefront-Shaping Optical Principle On A Toric Intraocular Lens Implant: A Prospective Study.

this prospective study aims to assess the visual performance and rotational stability of the toric extended depth-of-focus (EDOF) AcrySofÒ IQ VivityÒ intraocular lens implant.

the study was conducted as a monocentric, prospective, interventional trial at the eye department of Versailles Hospital in France.

Thirty-three patients underwent consecutive cataract surgeries on both eyes, with the study eye receiving an AcrySof® IQ Vivity® toric intraocular lens (IOL) ranging from T2 to T6. The fellow eye received either a toric or non-toric AcrySof® IQ Vivity® IOL toric based on keratometry. Preoperative and 3-month postoperative evaluations included assessment of reading performance. Monocular uncorrected and corrected distance visual acuity, as well as the smallest print size that can be read effectively are assessed at 40 cm and 66 cm distance. Additionally, binocular visual acuity and IOL rotation were measured.

Fourteen patients, with a mean age of 78.29 ± 7.45 years, were enrolled. At 3 months, on the study eye, the mean monocular corrected intermediate visual acuity was 0.14 ± 0.11 Logmar. Monocular uncorrected distance visual acuity was 0.05 ± 0.1 Logmar, monocular intermediate uncorrected visual acuity (66cm) was 0.16 ± 0.1, and monocular near uncorrected visual acuity was 0.42 ± 0.16. Binocular uncorrected visual acuity was 0.0 ± 0.05, binocular uncorrected intermediate visual acuity was 0.1 ± 0.1, and binocular uncorrected near visual acuity was 0.34 ± 0.17.

These intermediate results are consistent with the findings of the original pivotal studies. Detailed results of the 3-months-follow-up including reading performance and rotational stability, will be available for the 33 study eyes at the time of the meeting.
