Clinical Performance of a New Trifocal IOL with a 7.0 mm Optical Zone

Abstract

To evaluate the refractive and visual outcomes following cataract surgery and implantation of a diffractive trifocal intraocular lens (IOL) with a 7.0 mm optical zone.A total of 23 patients who underwent bilateral implantation with the Triva-aXAY IOL were analyzed at 6 months post-surgery. The main outcome measures were refractive error, monocular and binocular uncorrected and corrected-distance visual acuity (UDVA, CDVA), uncorrected and corrected-distance intermediate visual acuity (UIVA, CDIVA) at 60 cm, uncorrected and corrected-distance near visual acuity (UNVA, CDNVA) at 40 cm, and binocular defocus curve. Patients also completed the Catquest-9SF questionnaire.All eyes were within ±1.00D, and 91.30% of eyes within ±0.50D, with a mean postoperative spherical equivalent of -0.14±0.29D. Similarly, 95.65% of patients showed a binocular UDVA ≥20/25, compared to 100% for CDVA, and the mean binocular UDVA and CDVA were 0.02±0.06 and 0.00±0.05 logMAR, respectively. At intermediate vision, 65.22% of patients showed a binocular UIVA ≥20/25, compared to 86.96% for CDIVA, and the mean binocular UIVA and CDIVA were 0.07±0.06 and 0.06±0.06 logMAR, respectively. At near, 95.65% of patients showed a binocular UNVA and CDNVA ≥20/25, with a mean binocular UDNVA and CDNVA of 0.04±0.07 and 0.02±0.05 logMAR, respectively. Finally, 95.65% of patients reported being quite satisfied to very satisfied with their vision and about 74% did not report any difficulty with their vision in their everyday life. Between 65.22% and 100% of patients reported no difficulty performing different tasks.Our study shows good visual and refractive outcomes with high satisfaction in patients implanted with the Triva-aXAY IOL with a 7.0 mm optical zone.
