Comparison of visual and refractive outcomes between hydrophilic and hydrophobic trifocal intraocular lenses sharing the same optical design

Abstract

To compare clinical outcomes between two trifocal intraocular lenses (IOLs): the new FineVision POD FGF trifocal IOL made of hydrophobic acrylic glistening-free material, and the FineVision POD F IOL made of hydrophilic acrylic material with 26% water uptake in patients undergoing routine cataract surgery using standard phacoemulsification. Semmelweis University, Department of Ophthalmology, Budapest, Hungary. Prospective controlled randomized single-center single-surgeon study. Each patient had the hydrophilic POD F IOL implanted in one eye and the hydrophobic POD FGF IOL in the contralateral eye, according to a randomization table. Clinical outcomes included distance (4m), intermediate (70cm), and near (35cm) visual acuities, contrast sensitivity measured under photopic and mesopic conditions, and defocus curves under photopic conditions. The follow-up was 6months. The study comprised 25 patients. Under photopic conditions, there was no statistically significant difference between POD FGF and POD F IOLs for uncorrected distance (UDVA) (P=.607), uncorrected intermediate (UIVA) (P=.491), and uncorrected near (UNVA) (P=.414) visual acuities. Under mesopic conditions, there was no statistically significant differences between the 2 IOLs for UDVA (P=1.00), UIVA (P=.149), and UNVA (P=.551). No statistically significant differences in contrast sensitivity were found between the groups under photopic (P=.4347) and mesopic (P=.425) conditions. No safety issues were reported. The study demonstrated equally good visual andrefractive outcomes for the POD FGF IOL and the POD F IOL, giving the surgeon the option to choose the preferred material for the individual patient without compromising clinical outcomes.
