Efficacy, safety, and satisfaction in patients with a functional 5-focus pseudophakic lens 2 years after

Germán R. Bianchi (2025)

This ambispective, non-randomized study evaluated the visual performance, safety, and patient satisfaction of the Intensity SL (Hanita Lenses) five-focus pseudophakic intraocular lens (IOL) over a 24-month period. The study included 120 eyes of 60 patients who underwent femtosecond laser-assisted bilateral cataract surgery. At two years postoperatively, patients demonstrated excellent uncorrected visual acuity across far, intermediate, and near distances (binocular UDVA −0.05 ± 0.05 logMAR; UIVA 0.009 ± 0.05; UNVA 0.04 ± 0.06). Visual stability was maintained between the 6- and 24-month follow-ups. Dysphotopsias such as glare and halos were rare and mild. Patient satisfaction was remarkably high, with 95% reporting being "very satisfied" and 100% indicating they would choose the same IOL again. The findings support the long-term visual efficacy and quality-of-life benefits of the Intensity SL IOL.

Purpose:

To evaluate the safety, visual performance, and patient satisfaction of a new
presbyopic pseudophakic intraocular lens (IOL).

Methods:

An ambispective non-randomized study was performed in Buenos Aires, Argentina.
Patients included in the study underwent a programmed femtosecond laser-assisted cataract
surgery (FLACS), performed between October 2020 and September 2021, with a 24-month
follow-up period. The Intensity SL (Hanita Lenses) IOL was bilaterally implanted. Uncorrected
distance, intermediate, and near visual acuity (UDVA/UIVA/UNVA, respectively), and defocus
curve as well as safety parameters were measured, and patient satisfaction was evaluated
with the VF-14 QOL questionnaire.

Results:

A total of 120 eyes of 60 patients (34 women and 26 men) aged 68.32±8.9years
(54–85) were included. At the last follow-up, the mean monocular UDVA in eyes (n=120) with
an Intensity SL IOL implanted was 0.01±0.07logMAR, and the corrected distance visual
acuity (CDVA) was −0.05±0.06logMAR. For 120cm, mean UIVA was 0.06±0.11logMAR; for
80cm, mean UIVA was 0.07±0.07 logMAR; for 66cm, mean UIVA was 0.05±0.07 logMAR
and for 40cm, mean UNVA was 0.09±0.08 logMAR (−0.1 to 0.2). The mean binocular UDVA
in our patient group was −0.05±0.05logMAR. Glare and halo were rare phenomena. Patient
satisfaction was high. The mean score value of the VF-14 QOL questionnaire 24 months
postoperatively was 98.6.

Conclusion:

Patients underwent safe bilateral implantation with Intensity SL IOL, achieving
spectacle independence in most cases, and reported a high degree of satisfaction, refraction,
and vision stability 24 months after surgery.

This prospective study evaluated the performance of the Hanita Intensity penta-focal intraocular lens (IOL) in cataract and refractive lens exchange (RLE) patients over an 18-month period. The results demonstrated strong visual outcomes at all distances, with high patient satisfaction and statistically superior distance vision compared to PanOptix.

This study assessed the refractive outcomes, optical performance, and quality of vision in patients implanted with the Intensity Hanita diffractive intraocular lens (IOL). The prospective, observational study included 64 eyes that underwent bilateral cataract surgery with Intensity IOL implantation, with evaluations conducted at 6 months post-surgery. Results indicated that 66% of eyes achieved uncorrected distance visual acuity (UDVA) of 0.10 logMAR or better. The defocus curve showed optimal vision at distance (0.02 ± 0.07 logMAR at 0.0 D) with stable performance through intermediate and near vision ranges (0.11 ± 0.08 logMAR at -1.5 D, 0.12 ± 0.12 logMAR at -2.5 D). Contrast sensitivity remained stable (p ≥ 0.06), and high-order aberrations were low, with a Strehl ratio of 0.12 ± 0.04. Mild halos and glare were reported but did not interfere significantly with daily activities, and the near activity visual questionnaire (NAVQ) indicated high patient satisfaction with near-vision tasks. These findings support the Intensity Hanita IOL’s effectiveness in providing clear vision across all distances through a five-foci distribution design that enhances depth of focus.
