Gangnam ICL Clinic: Why is Corneal Endothelial Cell Examination Important?

Hello, this is Gangnam Smile Eye Clinic 😊

For severe myopia or astigmatism, in addition to laser corneal correction,

‘Implantable Collamer Lens (ICL) surgery’ should be considered.

The biggest advantage is that it preserves the cornea without ablation,

allowing for the correction of high myopia and high astigmatism.

However, there is an important examination to remember before undergoing ICL surgery.

This is the ‘corneal endothelial cell examination’.

This examination is absolutely necessary for the successful outcome and future stability of ICL surgery.

So, why is this examination important?

Let's take a closer look at what ICL surgery entails and how to manage it after the procedure.

Gangnam ICL Clinic: What is ICL surgery?

Unlike laser vision correction, which ablates the cornea,

ICL surgery corrects vision by implanting a special lens inside the eye.

It is typically suitable for patients with severe myopia or astigmatism, or thin corneas,

for whom conventional laser surgery is difficult.

The biggest advantage of this surgery is that it does not ablate the cornea,

resulting in less dry eyes, reduced glare, and almost no regression of myopia.

If vision is not perfectly corrected or discomfort occurs,

the intraocular lens can be easily removed, making it a highly safe procedure.

Furthermore, even in cases of astigmatism, an astigmatism-correcting lens can be implanted to achieve a corrective effect,

and stable vision can be maintained long-term.

The lenses used in ICL surgery are broadly divided into two types:

‘anterior chamber lenses’ and ‘posterior chamber lenses’.

An anterior chamber lens is placed in front of the iris,

while a posterior chamber lens is implanted behind the iris.

When using a posterior chamber lens, a pre-operative iridotomy is required.

Gangnam ICL Clinic: Precautions to Know Before ICL Surgery

The reason why corneal endothelial cell examination is important is that vision can be maintained through corneal endothelial cells.

The corneal endothelium is located in the innermost layer of the cornea

and plays a role in regulating corneal hydration and maintaining corneal clarity and transparency. However,

over time, these cells gradually decrease in number due to natural aging.

Although we are born with approximately 3,000 cells,

this number can continuously decrease to below 500.

If the number of corneal endothelial cells is less than the standard, permanent vision damage such as corneal edema and corneal opacity can occur, and cell damage may result.

Therefore, it is important to confirm this through examination.

Before surgery, a corneal endothelial cell examination should be performed to check the current number of corneal endothelial cells

and ensure the surgery is carried out safely.

If the cell count is too low, there may be vision problems after surgery,

so caution is needed during the procedure.

Gangnam ICL Clinic: Corneal Endothelial Cell Examination Recommended After ICL Surgery

Even after ICL surgery, corneal endothelial cell examinations should be performed regularly.

By having follow-up observations once every 6 months to 1 year after surgery,

changes in corneal endothelial cells can be quickly and easily checked.

Even if thorough examinations were conducted before surgery,

daily habits such as irritation or rubbing the eyes can have an impact,

leading to a decrease in corneal endothelial cells.

Therefore, it is recommended to measure corneal endothelial cell density at least once a year after surgery

and check for cataract progression, lens dislocation, etc.

If the number of corneal endothelial cells drops below 1,000,

the lens may need to be removed, but

it is rare to remove the lens unless there is severe trauma.

With regular examinations, vision can be maintained without major problems.

Before undergoing ICL surgery, it is important to check the health of your eyes through a corneal endothelial cell examination at an ICL clinic.

Since it plays a crucial role in maintaining vision and corneal transparency,

if the cell count is too low, it can be difficult to prevent side effects after surgery.

We hope you can achieve stable results through thorough examinations before and after surgery.

Consult with medical staff to choose the most suitable vision correction method for you.
