Abstract Details
Purpose:
To exploratory analyze factors that predict spectacle dependence following the implantation of trifocal intraocular lens (IOL).
Setting:
Prospective multicenter study.
Methods:
Sixty-six patients (age 66.2±7.5 years) with bilateral implantation of trifocal IOL (TFNT00: Alcon) were included in the analysis. Spectacle usage was assessed by patient questionnaire followed by a post-hoc correlation analysis of pre- and post-operative factors such as spherical equivalent (SE) and visual acuities (VA) at 5.0, 0.8, 0.6 and 0.4 meters.
Results:
Although 54 of 66 (81.8%) patients used spectacles preoperatively, 51 patients (77.3%) achieved overall spectacle independence postoperatively. Fifteen patients used occasionally: 12 used for readings and 3 for reading and distance view. Majority of the patients requiring spectacles reported difficulty in reading small prints. None of the patients used spectacles for distance vision exclusively. The age of patients using the spectacles was higher than that of spectacle independent patients (P=0.02, Wilcoxon test). Post-op SE and uncorrected near VA, however, were not significant predictors of spectacle dependence (P=0.21, 0.06).
Conclusions:
While the visual outcomes with this trifocal IOL were remarkable, a subset of patients required spectacles some of the time for near vision activities related with fine prints; and age may play factor in spectacle independence.
