Essential LASIK/LASEK Questions from Gangnam Station Eye Clinic

Hello from Gangnam Station Eye Clinic,

We are Gangnam Smile Eye Clinic😊💙

Recently, more and more people are considering vision correction surgery,

and many wonder, ‘What should I ask?’ before going for a consultation.

Today, Gangnam Station Eye Clinic will summarize three key questions

that are essential to ask during your LASIK/LASEK consultation.

Gangnam Station Eye Clinic: Is this corneal thickness acceptable?

Both LASIK and LASEK

correct vision by removing a certain thickness of corneal tissue, so

the safety of the ‘residual corneal thickness’ after surgery is very important.

The typical corneal thickness is around 500-550µm (micrometers),

and for procedures like New Smile LASIK, surgery is often possible

when the thickness is 490µm or more.

The U.S. FDA also recommends maintaining a residual cornea of at least 250-300µm

after surgery for safety.

Especially if you have high myopia or high astigmatism requiring significant correction,

the amount of tissue removed increases,

which may limit LASIK if your cornea is thin.

This is because a larger ablation zone can lead to an excessively thin residual cornea, causing structural instability,

and, though rare, can increase the risk of complications like corneal ectasia.

Therefore, it's not just about whether surgery is possible right now, but rather,

✅How stably the cornea will be maintained after surgery

✅Whether the residual cornea is sufficient

It is most important to get an accurate diagnosis on these points.

Gangnam Station Eye Clinic: What equipment and systems are good?

Even for the same LASIK/LASEK procedure,

the results can differ depending on the equipment used.

The latest equipment features

✅Real-time eye tracking

✅Customized laser adjustment according to corneal curvature

✅Precise astigmatism axis correction

These functions allow for more delicate correction.

Especially for those with astigmatism, the difference in equipment can be more significant.

Because astigmatism causes light to scatter rather than focus on a single point,

even a slight misalignment of the axis can reduce the correction effect

or result in residual astigmatism after surgery.

Therefore, what you must confirm during the consultation is:

✅How the astigmatism axis is measured

✅What system is used to prevent axis misalignment during surgery

✅Whether personalized laser treatment tailored to your eyes is possible

These are the three points.

If you have even a slight astigmatism,

checking whether precise equipment is used is a crucial point.

Gangnam Station Eye Clinic: What about glare or dry eyes after surgery?

The most commonly reported discomfort after vision correction surgery

is night glare.

This usually occurs due to the difference in size between the nocturnal pupil

and the corrected area (optical zone) treated by the laser.

It's a phenomenon where, when the pupil dilates in a dark environment after being fine during the day,

light outside the corrected range scatters and appears blurry.

Therefore, before surgery,

✅What is your nocturnal pupil size in mm?

✅Is the optical zone set wide enough compared to your pupil?

It's good to check these carefully.

Another concern is dry eyes,

which is a natural process that occurs due to temporary damage to corneal nerves during surgery,

leading to a decrease in tear secretion regulation.

If you frequently experience dryness,

✅Dry eye examination before surgery

✅Proceeding with surgery after treatment if necessary

Such procedures can be helpful.

Recently, there are also surgical methods that can reduce dry eyes,

so it's best to choose one that suits your eye condition.

Asking questions during a consultation is never a burden.

When asking these questions during a consultation,

you might worry about appearing like a difficult patient,

but good clinics actually trust patients who ask proactive questions more.

It's important to remember that LASIK/LASEK is not a one-size-fits-all surgery,

and the optimal method varies depending on various factors such as

corneal thickness, presence and axis of astigmatism, pupil size, and lifestyle.

Refer to the three questions summarized today

to prepare more thoroughly for your Gangnam Station Eye Clinic consultation,

and choose the safest and most satisfactory vision correction method for you.
