Comparison Of Clinical And Patient Reported Outcomes Between An Enhanced And A Standard Monofocal Intraocular Lens

To compare the clinical and patient reported outcomes of a TECNIS Eyhance (ICB) monofocal intraocular lens (IOL) with enhanced features for intermediate vision to the conventional TECNIS One (ZCB) monofocal IOL.

Private Refractive Surgery (Optical Express)

Data was reviewed on presbyopic patients who underwent cataract surgery or refractive lens exchange with either TECNIS Eyhance Monofocal (ICB), n=5,163 patients, or standard TECNIS One (ZCB) monofocal IOL, n=5,089 patients. Treatments were completed between October 2019 through January 2024. Patient age range was 40 to 85 years, with a preop refractive range of +6.00D to -11.00D sphere and up to -1.50D of refractive and corneal astigmatism. Postoperative clinical safety and efficacy outcomes up to 12 months, with a mean of 3 months, following implant were analysed.

UCDVA 20/25 or better was 91.5% in ICB and 91.8% ZCB (p=0.55), 31.1% ICB reached 20/16 or better and 46.7% ZCB (p<0.01). UCIVA 20/40 or better was 86.6% in ICB and 52.3% ZCB (p<0.01). UCNVA N8 or better was 68.9% in ICB and 27.3% ZCB (p<0.01). 1.7% of ICB eyes had loss of >2 lines BCVDA, 0.9% of ZCB (p<0.01). Mean difference between postop UCDVA and BCVDA was <1 line for both cohorts (p>0.05). Intended vs achieved SE ±0.5D was 81.6% for ICB and 81.4% for ZCB (p>0.05); ±1.0D was 96.3% and 94.3% (p<0.01). Intended vs achieved cylinder ±0.5D was 72.2% for ICB and 65.5% for ZCB (p<0.01); ±1.0D was 94.7% and 92.0% (p<0.01). Patient reported satisfaction was high for both cohorts (p>0.05). No significant difference in photic phenomena (p>0.05).

The TECNIS Eyhance proved to be a safe and effective monofocal IOL option. Performance is comparable to a standard monofocal lens at distance with improvements to UCIVA and UCNVA. Patient reported satisfaction is also high postoperatively for TECNIS Eyhance, with the added advantage of improved intermediate and near vision.
