Inclusion criteria were visually significant cataract and potential post-operative visual acuity of 20/25 or better. Endpoints included postoperative prediction error, refractive outcomes, uncorrected visual acuities at distance (UDVA), intermediate (UIVA), and near (UNVA), contrast sensitivity, and subject responses on the modified Visual Function Quality of Life Questionnaire (VF-14 QOL).Results: Binocular UDVA, UIVA, and UNVA were 20/25 or better in 100% (21/21), 100% (21/21), 90% (19/21) of subjects. The absolute prediction error was 0.50 D or less in 79% (33/42) of eyes, and 81% (34/42) and 86% (36/42) of eyes achieved ≤ 0.5 D of residual astigmatism and manifest refraction spherical equivalent, respectively. On the modified VF-14 QOL, driving at night, reading small print, and reading a newspaper or book were the tasks that had the lowest percentages of subjects reporting no difficulty or a little difficulty.Conclusion: Implantation with trifocal and trifocal toric IOLs using intraoperative aberrometry can provide high refractive precision, leading to excellent visual performance and low visual task difficulty at all ranges (distance, intermediate, and near).Plain Language Summary: An intraocular lens (IOL) is a clear artificial lens that can be used to replace the natural lens in the eye when the natural lens becomes opaque (develops a cataract). Monofocal IOLs are designed to provide good vision to see distant objects; however, spectacles may still be needed to see objects clearly up close (such as reading a book or using a digital device). Trifocal IOLs are designed to provide good vision to see objects at distance and up close, however, the power of the IOL must be accurately determined for the best visual outcomes.Devices called biometers are used by cataract surgeons to measure the eye and determine the most appropriate lens power to implant. Most biometers are used prior to surgery, however one type, intraoperative aberrometry (IA), can be used during surgery to measure the eye and determine the most appropriate lens power. The purpose of this study was to evaluate patient outcomes and visual function following trifocal IOL implantation using IA. The results of this study suggest that implantation with trifocal IOLs using IA can provide high refractive accuracy and excellent visual outcomes.Keywords: trifocal IOL, PanOptix, cataract surgery, intraoperative aberrometry
