Abstract Details

Purpose:

The purpose of this ongoing prospective multicenter clinical study is to investigate clinical outcomes and patient satisfaction after bilateral implantation of a hydrophobic trifocal non-toric intraocular lens (IOL), the new FINEVISION TRIUMF (POD L GF) manufactured by PhysIOL, Liège, Belgium. The IOL consists of additional powers of +3.5D for near and +1.75D for intermediate vision. The main difference between TRIUMF and other trifocal IOLs is the dominance and light distribution of additional power. TRIUMF shows dominance for the intermediate addition (+1.75 D).

Setting:

Semmelweis University - Department of Ophthalmology, Budapest, Hungary

Methods:

In this ongoing study, 26 subjects with cataractous eyes or clear lens exchange receive bilateral IOL implantation with TRIUMF. The follow-up examinations include: uncorrected (UDVA) and corrected distance visual acuities (CDVA), uncorrected (UIVA) and distance-corrected intermediate visual acuities (DCIVA), uncorrected (UNVA) and distance-corrected near visual acuities (DCNVA). Furthermore, distance-corrected defocus curves are recorded between -4.5D and +1.5D and contrast sensitivity testing is performed under mesopic and photopic light conditions. All exams are performed with Clinical Trial Suite (M&S Technologies, Niles, IL, USA). Additionally, postoperative patient satisfaction and spectacle independence is evaluated by a questionnaire.

Results:

The interim results on 50 eyes at 3M and 42 eyes at 6M postoperative show mean refractive outcomes of 0.36±0.39D and 0.34±0.38D respectively. Mean CDVA, DCIVA, DCNVA in logMAR are -0.06±0.07 0.11±0.10, 0.25±0.11 at 3 months, and -0.06±0.09 0.10±0.09, 0.23±0.12 at 6 months, respectively. Mean uncorrected visual acuity values for UDVA, UIVA, UNVA in logMAR are -0.06±0.07, 0.09±0.10, 0.23±0.09 at 3 months and -0.06±0.09, 0.09±0.11, 0.23±0.10, at 6 months, respectively. The presentation will contain the above mentioned examination results with a larger patient cohort and longer follow-up.

Conclusions:

Implantation of the hydrophobic trifocal intraocular lenses FINEVISION TRIUMF allows for a safe and efficient restoration of near, intermediate, and far visual acuity on patients undergoing lens exchange. In contrast to other trifocal IOLs, the current results show a smooth slope from distance to near visual acuities allowing for an enhanced intermediate visual acuity. This lens shows a high rate of spectacle independence is expected and the long-term outcomes on a larger patient cohort shall confirm these assumptions.
