Abstract
PURPOSE: To assess visual outcomes and patient satisfaction after refractive lens exchange followed by bilateral implantation of the multifocal Tecnis intraocular lens (IOL). METHODS: This prospective case series involved 59 eyes of 30 patients aged 56 +/- 8 years. Fifty-seven eyes were hyperopic (+3.52 +/- 1.80 diopters [D]) and 2 eyes were myopic (-1.12 +/- 0.53 D). Near, intermediate, and distance visual acuities were assessed at 1 and 6 months postoperatively. At last follow-up, patients were asked about their overall satisfaction, the occurrence of photic phenomena, difficulties driving at night, and spectacle independence. RESULTS: Six months after surgery and laser retreatment in 15 eyes, 90% of eyes achieved monocular uncorrected distance visual acuity of 20/30 or better (0.087 +/- 0.085 logMAR) and 100% of eyes could read J2 or better without correction, including 90% of eyes achieving J1 or better (0.133 +/- 0.095 logMAR). Evaluation of visual performance at 1 month versus 6 months (n = 44 eyes, no retreatment) revealed a considerable improvement of the uncorrected (0.175 +/- 0.122 vs 0.127 +/- 0.094 logMAR; P = .005) and distance-corrected (0.099 +/- 0.057 vs 0.068 +/- 0.031 logMAR; P = .001) near visual acuity whereas mean refractive errors and distance visual acuity remained unchanged. Overall, 96.4% of patients were very satisfied with the procedure and would choose the same lens again. The majority of patients (92.8%) were totally free from spectacles with only 7.2% occasionally wearing glasses for intermediate tasks. CONCLUSIONS: The multifocal Tecnis ZM900 IOL provides good distance and near vision after refractive lens exchange and a period of neuroadaptation. However, laser vision correction might be required to achieve emmetropia as well as spectacles to achieve good intermediate vision.
