“…With the obtained images, the pair lines of 4.00 lp/mm to 28.51 lp/mm (spatial frequency in object plane) in the USAF 1951 target were selected to calculate the contrast modulation using Eq. (5) [ 20 ]:

where CS is contrast modulation, I max is the maximum image intensity and I min is the minimum image intensity. The spatial frequency of the image pair lines on the CMOS image plane is converted according to the actual optical system magnification.…”

This study presents the fabrication and evaluation of a sinusoidal extended depth-of-focus (EDoF) intraocular lens (IOL) based on our previously proposed design approach. The power, through-focus MTF, and surface profile were measured using commercial instruments. Through-focus images of a United States Air Force (USAF) 1951 resolution target formed by the fabricated IOL were compared with Symfony and AR40E under monochromatic and polychromatic light using optical bench testing. Simulations assessed visual acuity (VA) of a pseudophakic model eye with the EDoF IOL, including evaluation of tilt and decentration effects. Results indicate that the base power, add power, and the through-focus MTF@50 lp/mm of the fabricated IOL at a 3 mm pupil size align with the design specifications. The extended-depth-of-focus and imaging performance for the far vision of the fabricated IOL under both monochromatic and polychromatic light conditions at a 3.0 mm pupil diameter is comparable to that of Symfony. In addition, the fabricated IOL exhibits a similar extended-depth-of-focus for three discrete wavelengths. The pseudophakic model eye with the designed EDoF IOL demonstrates a VA exceeding 0.1 logMAR within a defocus range of 2.44 D. The VA is tolerant to both IOL tilt and decentration. These findings demonstrate the promising potential of the sinusoidal EDoF IOL design for future applications in cataract surgery.

Introduction This study is a prospective, randomized, subject/evaluator-masked clinical trial in a single-center clinical setting. The purpose of the study is to compare the clinical performance of Tecnis Symfony Optiblue IOL (models ZXR00V and ZXW150) with violet light filter (VLF) and manufacturing improvements versus Tecnis Symfony IOL (models ZXR00 and ZXT150) with ultraviolet light filter (UVF) in patients undergoing cataract surgery. Methods Patients with cataracts aged ≥ 22 years were randomly assigned 1:1 to bilateral implantation with ZXR00V/ZXW150 (VLF group) or ZXR00/ZXT150 (UVF group). Key endpoints at 6 months postoperative included patient reported nighttime dysphotopsia symptoms, 25% low contrast visual acuity with glare, and patient satisfaction. Results Sixty patients were implanted with ZXR00V/ZXW150 (30) or ZXR00/ZXT150 (30). At 6 months, the VLF group did not show a statistically significant differences in mean monocular photopic uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), uncorrected near visual acuity (UCNVA) (40 cm), or distance-corrected near visual acuity (DCNVA) (40 cm) compared to the UVF group. At 1 month, patients in the VLF group reported significantly less difficulty due to halo (p = 0.016) and starburst (p = 0.028) symptoms. By the 6 months, dysphotopsia complaints were no longer significantly different between the groups. Although the VLF group trended toward better low contrast visual acuity and patient satisfaction, statistical significance was not reached. Conclusions Managing the patients’ expectations is key to achieving success. At the 1-month visit the patients who reported dysphotopsia complaints in the VLF group had significantly less difficulty with starbursts and halos as compared to the UVF group. By the 6-month visit, there was no significant difference between the two groups in the difficulty with starbursts and halos. Trial Registration ClinicalTrials.gov identifier, NCT06567834.
