PRELIMINARY OUTCOMES OF A TORIC ENHANCED DEPTH-OF-FOCUS INTRAOCULAR LENS IN EYES WITH LOW AMOUNTS OF CORNEAL ASTIGMATISM

The purpose of this study is to assess the refractive and visual outcomes in a series of eyes with low astigmatism implanted with the enhanced depth-of-focus (EDOF) AcrySof IQ Vivity toric DFT215 IOL.

This preliminary prospective consecutive single-arm study was conducted in accordance with the tenets of the Declaration of Helsinki and approved by the Ethics Committee of the Hospital Clínico San Carlos (Madrid, Spain) and the Valencia regional committee on postmarketing studies CAEPRO (Valencia, Spain). All patients provided written informed consent before they were enrolled in the study. Inclusion Criteria considered age-related cataract surgery patients, corneal astigmatism ≤1.00D (EDOF DFT215 candidate at least in one eye) and age between 55 to 85 years. Exclusion criteria were dry eye or tear film alteration assessed using the Keratograph 5M device (i.e. NIKBUT), glaucoma, retina or corneal disease, and previous corneal or intraocular surgery

Monocular uncorrected and corrected distance visual acuity, uncorrected and corrected distance monocular intermediate (66 cm) and near (40 cm), subjective refraction and rotational stability were measured in 15 patients. Monocular defocus curve (from +1.00D to -3.00D, 0.50D steps) was also determined. Specifically, IOLSat and QUVID questionnaires preoperatively and at 3 months post-surgery were used. All patients were candidates to cataract surgery with astigmatism and implanted with the EDOF AcrySof IQ Vivity toric DFT215 IOL. All surgeries will be done using ORA intraoperative aberrometry using the same surgical technique, equipment and postoperative treatment. All patients were implanted with the EDOF AcrySof IQ Vivity IOL bilaterally but only one eye per patient, implanted with the toric model, were included in the statistical analysis. IOL power calculation was performed with the Alcon IOL Toric Calculation (Barrett formula)

The use of the EDOF AcrySof IQ Vivity toric DFT215 IOL in patients with low amount of astigmatism provides accurate refractive outcomes and good visual acuity.
