Abstract
Purpose: To evaluate clinical and visual outcomes, quality of near vision, and intraocular optical quality of patients bilaterally implanted with a trifocal PanOptix intraocular lens. Methods: In this prospective consecutive case-series study, 52 eyes of 26 bilateral patients (mean age, 60.2 +/- 7.4years) were implanted with the AcrySof IQ Panoptix intraocular lens. Visual acuity, defocus curve, contrast sensitivity (PelliRobson test), near activity visual questionnaire, and internal aberrations with Osiris were evaluated. A prototype lightdistortion analyzer was used to quantify the postoperative light-distortion indices. The follow-up was 6 months after surgery. Results: Uncorrected, corrected distance, and uncorrected near visual acuities improved with the surgery (p<0.02). Distance corrected near visual acuity was 0.13 +/- 0.10, 0.13 +/- 0.13, and 0.13 +/- 0.08 at 1,3, and 6months after surgery, respectively (p = 0.82). Distance corrected intermediate visual acuities were 0.09 +/- 0.13, 0.13 +/- 0.15, and 0.12 +/- 0.12 at 1, 3, and 6months, postoperatively. Binocular contrast sensitivity was 1.86 +/- 0.15 Log Units. Defocus curve provided a visual acuity equal or better to 0.30LogMAR between defocus levels of +0.50 to -3.00 D. The near activity visual questionnaire scores improved significantly with the surgery (p < 0.01). Conclusion: The AcrySof IQ Panoptix intraocular lens is able to restore visual function with an acceptable intermediate and near vision after cataract surgery with good contrast sensitivity and an improvement in the near activity visual questionnaire.This publication has 24 references indexed in Scilit:
