High Myopia SMILE Pro: Why Greater Caution is Needed with Higher Prescriptions

Hello, this is Gangnam Smile Eye Clinic 😊💙

Among those considering vision correction surgery, many often ask:

‘Is SMILE LASIK possible even with a high prescription?’

Indeed, high myopia or high astigmatism involves many more factors to consider than typical myopia.

This is because it's not just about correcting vision, but about how safely the cornea can be preserved while achieving the target vision.

Today, we will explore the essential factors to check when planning high myopia SMILE LASIK and why equipment precision is crucial.

What is High Myopia?

Generally, a severe state of myopia is called high myopia, and higher prescriptions often require more corneal correction.

However, not all high myopia is the same.

Factors such as sufficient corneal thickness, presence of astigmatism, pupil size, and normal corneal shape must all be checked together to determine surgical eligibility and the appropriate method.

Therefore, it is difficult to decide on surgery based solely on the prescription.

Why is Equipment More Important for High Myopia?

As the prescription increases, accuracy becomes paramount.

Since high myopia can lead to an increased amount of corneal ablation, minimizing unnecessary ablation is crucial.

Furthermore, how accurately the data obtained from pre-operative examinations is reflected in the surgical process significantly impacts the outcome.

Thus, recently, not only the experience of the medical staff but also precise diagnostic equipment and surgical systems are considered equally important.

It's Even More Challenging with Coexisting High Astigmatism.

When high myopia is accompanied by astigmatism, another variable arises:

the astigmatism axis.

Even a slight deviation in the astigmatism axis can reduce the correction effect, potentially leading to decreased clarity after surgery or night glare.

For example, if the astigmatism axis is off by just a few degrees, the correction effect can diminish, making it crucial to maintain stable eye centering and rotation during surgery.

Therefore, for patients with high astigmatism, a process that accurately reflects axis information from the examination stage to the surgical stage is necessary.

A System Where Examination Data is Directly Linked to Surgery

In the past, examinations and surgeries were often conducted separately.

However, recently, systems that automatically link examination data with surgical equipment are being implemented.

Gangnam Smile Eye Clinic's Smart Nova, also known as New SMILE Pro, utilizes the CenTrax® system, which is linked with the SIRIUS diagnostic device.

This system reflects the eye's centering information and data confirmed during the examination in real-time during the surgical process, and it is designed to continuously recognize eye movements or changes in centering that may occur during surgery, minimizing errors.

Four Core Technologies of New SMILE Pro, Smart Nova

1. Centering Correction Function

Automatically recognizes and aligns the eye's center, helping to ensure a more stable surgery.

This function is particularly important for high myopia, as even a slight deviation from the center can affect the quality of vision.

2. CenTrax Automatic Interlocking System

Automatically retrieves pre-operative examination data and reflects the center coordinates in real-time.

This reduces errors that can occur during the information transfer process between examination and surgery, enabling more precise correction.

3. Precise Design Down to Refractive Values

Myopia and astigmatism vary greatly from person to person.

Smart Nova is designed to reflect even minute refractive values, allowing for personalized surgical plans.

This is especially crucial for patients with high myopia and high astigmatism.

4. LOW Energy System

This method avoids using more laser energy than necessary, helping to reduce the burden on corneal tissue.

It can also be expected to have a positive impact on early vision recovery.

Ultimately, the Combination of Medical Staff and System is Key

No matter how good the equipment is, the outcome is not solely determined by it.

✔Precise pre-operative examination,

✔Customized design for each patient,

✔The experience of the medical staff,

✔And the equipment that implements these

must all be in place to expect highly satisfactory results.

Especially for patients with high myopia or high astigmatism, it's important to confirm ‘how to perform the surgery more precisely’ rather than just ‘is surgery possible?’

If You Are Considering High Myopia SMILE LASIK

High myopia and high astigmatism often require a more delicate approach than general vision correction.

Gangnam Smile Eye Clinic precisely analyzes each individual's eye condition and then guides them to the appropriate surgical method, striving to enhance accuracy from examination to surgery through the SMART NOVA system.

If you are considering vision correction, please undergo a thorough precise examination to first check your eye condition.

Frequently Asked Questions

Is SMILE LASIK surgery possible for high myopia?

Yes, it is possible. However, for high myopia, various factors such as corneal thickness, presence of astigmatism, pupil size, and corneal shape must be comprehensively checked to determine the feasibility of surgery and the appropriate method. It is difficult to judge based solely on the prescription.

Why is the precision of the equipment important for high myopia SMILE LASIK?

Because high myopia may involve an increased amount of corneal ablation, it is crucial to minimize unnecessary ablation. Additionally, the accuracy with which pre-operative examination data is reflected in the surgical process significantly impacts the outcome, making precise equipment essential.

Is SMILE LASIK more challenging for high astigmatism?

Yes, it can be more challenging. Even a slight deviation in the astigmatism axis can reduce the corrective effect, decrease clarity, or cause night glare. Therefore, accurately reflecting astigmatism axis information from examination to surgery is important.

What are the key technologies of the Smart Nova system?

The Smart Nova system features four core technologies. It assists in precise and safe surgery through its central correction function, CenTrax automatic interlocking system, precise design down to refractive value units, and a LOW energy system.

What is the most important factor for successful SMILE LASIK?

The most important factor is the combination of the medical team and the system. Satisfactory results can be expected only when precise pre-operative examinations, customized patient design, the medical team's experience, and precise equipment to implement these are all in place.
