Purpose

Higher-order aberrations (HOA) including spherical aberrations (SA) are crucial to retinal image quality and depth of focus. In modern cataract surgery, enhanced monofocal intraocular lenses (IOLs) aim to improve intermediate vision by modulating specific higher-order wavefront parameters. Therefore, this prospective, intraindividual, fellow-eye clinical study compared the visual performance of an aspheric enhanced monofocal IOL with a spherical monofocal IOL, with a particular focus on intermediate and near distance.

Setting

This single-center, prospective clinical trial was conducted at the Department of Ophthalmology, Medical University of Vienna.

Methods

A total of 100 eyes of 50 patients scheduled for bilateral cataract surgery were included in this prospective clinical trial. An aspheric enhanced monofocal Tecnis Eyhance ICB00 IOL was implanted in the dominant eye and a spherical monofocal Sensar 1-piece AAB00 IOL in the non-dominant eye (both Johnson&Johnson Vision). Two to four months postoperatively, intraindividual comparison included monocular, best-corrected (BCDVA/BCNVA), distance-corrected (DCIVA/DCNVA) and low contrast visual acuities at various distances, monocular distance-corrected defocus curves, wavefront analysis, tilt and decentration.

Results

Results of monocular 80cm DCIVA, 66cm DCIVA and 40cm DCNVA demonstrated significant differences: For the ICB00 IOL, the logMAR values were 0.24±0.12, 0.33±0.13, and 0.49±0.17, while for the AAB00 IOL, the values were 0.31±0.11 (p< .001), 0.37±0.13 (p= .007), and 0.56±0.13 logMAR (p= .003) respectively. Furthermore, monocular 66cm low-contrast visual acuity (ICB00: 0.49±0.12, AAB00: 0.53±0.13 logMAR, p= .048), BCNVA (ICB00: 0.05±0.08, AAB00: 0.09±0.10 logMAR, p= .006), monocular distance-corrected defocus curves from -0.25D to -1.50D (p< .05) and internal SA at 3mm and 5mm pupil diameter (p< .001) showed significant differences. Comparable results were observed for BCDVA, total internal HOA, tilt and decentration (p> .05).

Conclusions

In this prospective, intraindividual comparison between the aspheric enhanced monofocal Tecnis Eyhance ICB00 IOL and the spherical monofocal Sensar 1-piece AAB00 IOL, the enhanced monofocal IOL achieved better monocular intermediate and near visual acuity, while distance visual acuity was comparable in both groups. Decentration, tilt, and HOA were low in both groups.
