PURPOSE: To evaluate the 5-year visual outcomes, refractive stability, IOL centration, patient satisfaction, and complications following trifocal intraocular lens (IOL) implantation in a Chinese cohort.
DESIGN: Retrospective study.
SUBJECTS: This study included 33 patients (66 eyes) with bilateral implantation of the AT LISA 839MP trifocal IOL.
METHODS: Postoperative assessments at 5 years included uncorrected and corrected distance, intermediate and near visual acuity, refractive outcomes, contrast sensitivity (CS), defocus curves, reading speed, and patient-reported outcomes (VFQ-25 questionnaire). IOL tilt/decentration and aberrometry were analyzed using anterior segment optical coherence tomography (AS-OCT) and iTrace visual function analyzer.
MAIN OUTCOME MEASURES: Postoperative outcomes at 5 years: uncorrected and corrected visual acuity (distance, intermediate, near), refractive results, and IOL centration.
RESULTS: At 5 years, mean UDVA, UIVA, and UNVA were 0.06 ± 0.16, 0.10 ± 0.14, and 0.09 ± 0.12 logMAR, respectively. 92.4% of eyes achieved a postoperative spherical equivalent within ±1.0D. Over 87.9% of patients achieved spectacle independence. Mean IOL tilt was 4.19 ± 1.46° and mean IOL decentration was 0.21 ± 0.11 mm. Contrast sensitivity declined under glare, particularly at mesopic conditions. Moderate-to-severe halos were reported by 21.2% of patients, correlating significantly with IOL tilt. Posterior capsule opacification necessitated Nd:YAG capsulotomy in 63.6% of eyes (mean intervention time: 22.0 ± 9.9 months), with no complications post-procedure. Patient satisfaction remained high (VFQ-25 score: 93.9 ± 13.7), despite persistent dysphotopsias.
CONCLUSION: Trifocal IOLs provided long-term efficacy in visual acuity, refractive stability, and exceptional patient satisfaction among Chinese populations. However, PCO remains a prevalent late complication, requiring timely Nd:YAG intervention. IOL tilt significantly influences halo severity.
