Hanita Korea recently hosted approximately 30 ophthalmologists from the Korea University alumni network for an in-depth clinical discussion on the Intensity® intraocular lens (IOL), focusing on real-world outcomes and surgical insights in modern cataract and refractive lens exchange procedures.
A special thank you to Dr. Youngsub Eom (Yes Eye Center) for presenting his clinical experience with Intensity®, with the following key takeaways:
🔹 Sinusoidal Design: Highlighted the unique benefits of the sinusoidal optical design with its base power optimized for intermediate distance.
🔹 Pupil-Optimized Energy Distribution: Explained how smart energy distribution tailored to pupil size not only enhances visual acuity but also significantly reduces glare.
🔹 Impressive Defocus Curve: Demonstrated a remarkably flat defocus curve, maintaining 1.0 VA across all distances from +0.5 to -2.0 D.
🔹 Optical Bench Test: Shared his own USAF resolution chart data, proving Intensity provides the widest visual range compared to other multifocal IOLs.
About the Speaker
Dr. Eom is a recognized key opinion leader (KOL) in the field of IOL power calculation and a member of the IOL Power Club (IPC). He is also the developer of the widely used Eom IOL Power Calculator, available here: https://www.eomiolcalc.com/
In a recent large-scale 2025 study evaluating 36 IOL calculation formulas by leading experts including Kenneth J. Hoffer and David L. Cooke, the Eom formula ranked among the top-performing methods in terms of predictive accuracy.
Additional valuable insights were shared by Dr. Junheon Kim (Gangnam Joeun Nun Eye Clinic), based on long-term clinical experience:
💡 He highlighted the exceptional patient satisfaction with Intensity, noting its strong premium positioning in the Japanese market.
💡 Clinical Tip: He emphasized that Intensity and Intensity Toric have different lens constants and should be treated as entirely separate products.
💡 He also added that despite the Toric model being a plate-haptic design, he has experienced excellent long-term refractive stability even without using a capsular tension ring (CTR).
This session reflects the importance of ongoing collaboration between surgeons and industry in refining clinical approaches and optimizing patient outcomes in premium cataract surgery.
Hanita Lenses remains committed to supporting ophthalmologists worldwide with advanced IOL technologies and evidence-based solutions for improved visual performance.
