Abstract
PurposeTo 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.MethodsThe 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.ResultsThe study enrolled 58 consecutive patients. Binocular UDVA, UIVA and UNVA were − 0.08 ± 0.07 logMAR, 0.15 ± 0.14 logMAR and 0.17 ± 0.11 logMAR at 1 month, compared to − 0.09 ± 0.06 logMAR (P = .323), 0.11 ± 0.10 logMAR (P = .030) and 0.13 ± 0.10 logMAR (P = 0.008) 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 ± 0.94 and 7.88 ± 1.74 at 1 month, compared to 9.24 ± 0.78 (P = .183) and 8.26 ± 1.38 (P = .043) at 12 months.ConclusionsThis 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.
Highlights
Various methodologies have been introduced in modern day lens-based surgery to provide a range of clear vision [1,2,3,4,5,6] with the least amount of visual side effects
The extended depth of focus (EDOF) intraocular lens (IOL) was used in the dominant eye to provide good distance, intermediate and improve near vision and produce fewer unwanted visual phenomena, with the trifocal IOL implanted in the nondominant eye to provide adequate reading vision
Our recent study outlined the early postoperative outcomes found after implantation of a new EDOF IOL in combination with a trifocal IOL [7]
Summary
Various methodologies have been introduced in modern day lens-based surgery to provide a range of clear vision [1,2,3,4,5,6] with the least amount of visual side effects. The EDOF IOL was used in the dominant eye to provide good distance, intermediate and improve near vision and produce fewer unwanted visual phenomena, with the trifocal IOL implanted in the nondominant eye to provide adequate reading vision. This recent study [7] reported that the combination of an EDOF and trifocal IOL provides good unaided visual acuity for distance, and near distances, providing high postoperative satisfaction and functional vision, at an early postoperative stage. This current study sought to outline the objective visual and refractive outcomes, and patient satisfaction of this IOL combination in a cohort of patients at a longer postoperative period of 1 year, and to determine whether the objective and subjective outcomes altered over this postoperative period
