Abstract Details

Purpose:

To compare the clinical results after bilateral implantation of trifocal intraocular lenses (IOLs) sharing a very similar optic design but differing in the lens material (hydrophilic vs. hydrophobic).

Setting:

Asian Eye Institute, Manila, Philippines.

Methods:

A total of 100 eyes of 50 patients underwent phacoemulsification and were included in this study. Patients were randomized into 2 groups and received a hydrophobic (PODFGF) or hydrophilic (PODF) trifocal FineVision IOL implantation (both PhysIOL, Liège, Belgium). Follow-up examinations were planned for 1 day, 1 week, 1 month, 3 months, 1 year and 2 years postoperatively and included uncorrected and distance-corrected visual acuity for distance (UDVA, CDVA), intermediate (UIVA, DCIVA), and near (UNVA, DCNVA), refraction, defocus curve, contrast sensitivity under photopic and mesopic light conditions, ocular scatter index, and patient satisfaction (questionnaire).

Results:

At 3 months, interim analysis (22 patients/44 eyes per group) showed no statistically significant differences between the groups. Mean logMAR UDVA (PODF: 0.06±0.09; PODFGF: 0.05±0.07), UIVA (PODF: 0.09±0.09; PODFGF: 0.09±0.12), and UNVA (PODF: 0.08±0.09; PODFGF: 0.11±0.14) were very good. In both groups, the binocular defocus range was broad with visual acuities of ≤0.3 logMAR from 24 cm to infinity. Photopic and mesopic contrast sensitivity were within the normal range. More than 80% (PODF) and 70% (PODFGF) of patients were completely independent from glasses and all patients were very satisfied or satisfied with their overall vision.

Conclusions:

Both lenses, the hydrophilic and the hydrophobic trifocal FineVision IOL, provided an excellent level of visual performance and patient satisfaction. Both IOLs restored visual functions for far, intermediate and near distances. The hydrophilic lens showed slight advantage on near vision without statistical significance. The postoperative spectacle independence rate was very high in both groups, which is reflected in the high level of patient satisfaction. The availability of trifocal IOLs with exceptional clinical performance and no significant differences in the outcomes allows the surgeon to choose his preferred IOL material while matching the individual preference and patients’ needs.
