70% of astigmatism correction ICLs performed in Korea insert lenses that fit tightly into the eye by using a large lens to prevent lens rotation. Even though using this method does not show immediate issues, it could lead to side effects in the future.
Based on the clinical experience of over 50,000 cases accumulated since 2002, Seoul Busan BGSS Eye Clinic has developed a vertical astigmatism algorithm and created the first vertical ICL procedure.

Accurate Measurement of the Eye
It is important to accurately measure the space inside the eye to determine if there is enough space for the lens to be inserted. This measurement helps determine the lens size and insertion location, which minimizes the possibility of lens rotation. V-Toric ICL is designed to accommodate the eye’s natural shape, as the vertical diameter is typically longer than the horizontal. This design allows for a generously sized lens to be inserted into the larger area without any contact around the periphery of the lens. As a result, the surgery has fewer side effects and the lens has higher stability.

Preventing Changes in Astigmatism Axis
Stable astigmatism correction can be achieved only when the degree and the type of astigmatism are accurately identified and there is no change in the astigmatism axis.
With the help of downward gravity, implanting a lens vertically reduces the chance of rotation, allowing for a stable vision as there are minimal changes in the axial position.
The current method of horizontal lens insertion may cause a 90-degree rotation, altering the axis position.
The 3rd generation V-Toric ICL is inserted vertically to minimize rotation and position change of the axis.
Correct Lens Size
When inserting a lens horizontally, a larger lens is used to minimize rotation, which can lead to increased intraocular pressure and eventually cataracts and glaucoma.
V-Toric ICL prevents side effects such as increased intraocular pressure and endothelial cell damage by inserting a lens tailored to the eye’s vertical diameter, allowing for sufficient space.

2023 [35th Asia-Pacific Association of Cataract and Refractive Surgeons]
The V-Toric ICL developed by Seoul Busan BGSS Eye Clinic reduces the possibility of astigmatic lens rotation. It has won the Best Post Award at Asia's largest academic society for its academic value and contribution to development.
April 2023 [129th Korean
Ophthalmological Society]
'Clinical Results and Comparative Study of Vertical Insertion for Rotational Safety of Lens Implantation' demonstrates that the vertical insertion method provides better rotational stability and excellent vision correction with lower vaulting. It can replace the existing horizontal insertion technique.
2023 [KSCRS Korean Society of Cataract and Refractive Surgery Academic Conference]
Our center's V-Toric ICL, tailored to the vertical diameter, won the best paper award for being a highly effective treatment method that maintains stability and improves vision quality.
