Visual outcomes and patient satisfaction 1 and 12 months after combined implantation of extended depth of focus and trifocal intraocular lenses

Abstract

To assess the 1-month and 12-month postoperative visual performance and subjective outcomes following combined implantation of an extended depth of focus (EDOF) intraocular lens (IOL) and a trifocal IOL. The study enrolled consecutive patients undergoing refractive lens extraction or cataract surgery with combined implantation of an EDOF IOL (dominant eye) and trifocal IOL. Uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, and subjective questionnaires were evaluated 1 month and 12 months postoperatively. The study enrolled 58 consecutive patients. Binocular UDVA, UIVA and UNVA were −\u20090.08\u2009±\u20090.07 logMAR, 0.15\u2009±\u20090.14 logMAR and 0.17\u2009±\u20090.11 logMAR at 1 month, compared to −\u20090.09\u2009±\u20090.06 logMAR (P\u2009=\u2009.323), 0.11\u2009±\u20090.10 logMAR (P\u2009=\u2009.030) and 0.13\u2009±\u20090.10 logMAR (P\u2009=\u20090.008) at 12 months. Satisfaction was high with 93.1% of patients fulfilled or more than fulfilled postoperatively, and 84.5% and 86.3% reported spectacle independence for near at the respective postoperative assessments. The mean daytime and nighttime quality of vision (QoV) scores were 9.12\u2009±\u20090.94 and 7.88\u2009±\u20091.74 at 1 month, compared to 9.24\u2009±\u20090.78 (P\u2009=\u2009.183) and 8.26\u2009±\u20091.38 (P\u2009=\u2009.043) at 12 months. This IOL combination provides good unaided visual acuity at 1 and 12 months postoperatively, with high functional vision and postoperative satisfaction reported at 1 and 12 months. However, a significant improvement in overall nighttime QoV at the 12 months assessment was found.
