Dr. Hannuy Choi, Chief Director of B&VIIT Eye Center, presented groundbreaking research on vertical insertion of Implantable Collamer Lenses (ICL). This presentation took place at the European Society of Cataract and Refractive Surgeons (ESCRS 2025). It is one of the world’s top three ophthalmology congresses.
The study drew significant attention. It introduced a minimally invasive vertical lens insertion technique. This technique leverages an AI-based sizing prediction program. It helps to prevent corneal damage while achieving stable vault adjustment.
AI and Vertical Insertion: Enhancing ICL Safety
ICL surgery corrects vision by implanting a biocompatible lens inside the eye. A critical factor in surgical success is the vault—the distance between the implanted lens and the natural crystalline lens.
- If the vault is too low, the lens may contact the crystalline lens, increasing the risk of cataract formation.
- If the vault is too high, excessive pressure on the cornea may reduce endothelial cell density.
Accurately predicting lens size and insertion position is essential. These predictions must be based on each patient’s unique ocular structure. This is crucial for safe and successful outcomes.
B&VIIT Eye Center, together with its subsidiary VISUWORKS, has developed an AI-powered sizing prediction program. The system analyzes precise ocular data. It includes anterior chamber depth and corneal curvature. This information helps determine the optimal lens size and insertion orientation.
This study confirmed that vertical insertion, tailored to individual eye anatomy, improves vault stability. It also enhances visual prognosis compared to conventional horizontal insertion.
Global Recognition and Clinical Impact
International ophthalmologists praised the research for its scientific rigor. They noted its clinical applicability and particular significance in reflecting the anatomical characteristics of Asian eyes. Many highlighted the study’s innovative integration of AI technology into lens implantation, improving predictive accuracy and surgical planning.
Dr. Choi emphasized:
“Using AI-based sizing prediction for ICL surgery is key to enhancing long-term post-operative stability. We will continue to provide patients with the best possible vision. We aim to improve their quality of life through evidence-based diagnostics. We also ensure safe surgical practices.”
Dr. Choi has performed thousands of ICL procedures. She continues to conduct research to ensure the long-term safety and effectiveness of implanted lenses.
