To evaluate the visual outcomes after bilateral implantation of a diffractive trifocal intraocular lens, (Finevision, PhysIOL) following clear lens extraction.
A retrospective review of all patients who had refractive lens exchange and implantation of FineVision trifocal intraocular lens were included. The inclusion criteria included: clear lens, patient interest in spectacle independence, corneal astigmatism less than 0.75 diopter. Exclusion criteria included: Previous ocular surgery, past ophthalmic history of ocular disease (other than refractive error or amblyopia) and corneal astigmatisms of more than 0.75D. The main outcomes were binocular uncorrected distance (UDVA), corrected distance (CDVA), intermediate at 65cm (UIVA) and near at 40cm (UNVA) visual acuity. The refractive target was emmetropia. Additionally, binocular defocus curves, mesopic and photopic contrast sensitibity were measured and a patient satisfaction questionnaire (Catquest-9SF) was applied.
Total of 20 eyes (70% males, 30% females) with a mean age at surgery of 58 +/-5.4 years. All the patients had a hyperopic error. Mean Spherical equivalent was 3.40 +/- 2.16 D. The mean postoperative logMAR UDVA, CDVA, UIVA and UNVA was 0.11 +/- 0.13, 0.04 +/- 0.06, 0.06 +/- 0.13 and 0.05 +/- 0.10. The difference between preoperative CDVA (0.07+/-0.11) and postoperative UDVA (0.11+/-0.13) was not statistically significant (p=0.3). The defocus curves showed that the best visual acuity was reached at a 0.00D. At -3.00 D reached 0.34 logMAR (20/44). The visual acuity steadily improved between -3.00 and -1.50 D, reaching a value of 0.06 logMAR (20/23). Postoperative contrast sensitivity values were within the ranges of normality for all spatial frequencies evaluated. Mean Catquest 9SF score was 1.14 +/-0.17. Patient satisfaction score was 9.3 +/- 0.9. 90% of the patients graded their satisfaction between 9 and 10. Spectacle Independence was 100% for distance and only 10% patients required reading glasses.
Implantation of FV trifocal IOL following refractive lens exchange appears to be safe and effective in patients with hyperopic error and presbyopia, as an alternative for achieving spectacle independence. Good uncorrected visual acuity at distance, intermediate and near distances were achieved
