Abstract

Purpose
To compare the clinical outcomes of cataract surgery using the Primus-HD^® intraocular lens (IOL) and conventional ARTIS^® PL E IOL.
Methods
The study retrospectively enrolled 242 eyes of 151 patients who had undergone cataract surgery with either ARTIS^® PL E (Group A) or Primus-HD^® (Group B) IOLs between April 19th, 2021 and November 30th, 2022 at Severance Hospital, Yonsei University College of Medicine. Eyes with a history of ocular surgery or trauma or ocular comorbidities that can affect postoperative visual outcomes were excluded. Finally, 69 eyes in group A and 36 eyes in group B were analyzed.
Results
At postoperative 3 months, there was no significant difference in uncorrected (0.15 ± 0.17 vs. 0.17 ± 0.18 in group A and B, p = 0.60) and best-corrected distance visual acuity (0.03 ± 0.06 vs. 0.02 ± 0.05 in group A and B, p = 0.75) between groups A and B. Postoperative uncorrected intermediate and near visual acuity, spherical equivalent and amount of myopic shifting were also similar between the two groups. The mean absolute error of the Barrett Universal II (0.61 ± 0.42 D vs. 0.28 ± 0.17 D in group A and B, p < 0.01) and Haigis (0.51 ± 0.38 D vs. 0.33 ± 0.23 D in group A and B, p = 0.01) formulas were significantly lower in group B compared with group A, showing good predictability. There was no significant difference between the higher order aberrations of the two groups at postoperative 3 months.
Conclusions
The postoperative corrected and uncorrected distance visual acuity, predictability and higher order aberration outcomes of cataract surgeries using the Primus-HD^® were comparable with results to ARTIS^® PL E, whose efficacy and safety had previously been clinically verified.
