LASIK vs. LASEK: Understanding Vision Correction Options at a Seocho-gu Eye Clinic
Hello.
I'm Dr. Lee Min-ji, head director of Gangnam ID Eye Clinic.
I'm greeting you again today.
During seasonal changes, when the temperature drops sharply in the morning and evening,
eye health is easily compromised. Dry air and
significant daily temperature variations increase eye fatigue and
cause dryness.
Therefore, during seasonal changes, it's essential to manage your eye health by using artificial tears,
utilizing humidifiers, and getting enough sleep. However, those who already experience discomfort
due to vision impairment and rely on glasses or lenses
may experience even greater inconvenience.
Although glasses and lenses can provide temporary correction,
they don't offer a fundamental solution. Therefore,
you might consider vision correction surgery to restore your eyesight
without the need for glasses or lenses.
In fact, the upcoming winter vacation season is a time when students
have more free time than during the school year, and office workers can
utilize their year-end holidays to secure recovery time.
This is why many people considering vision correction surgery
visit our clinic during this period.
Therefore, today, we will take the time to examine the differences and
characteristics of LASIK, LASEK, and other vision correction methods
at our Seocho-gu eye clinic.
“LASIK and LASEK: Limitations of Vision Correction Surgery”
LASIK and LASEK, which are representative vision correction methods,
differ in vision correction techniques, recovery speed, and other aspects.
Therefore, it's important to choose the method that is most suitable
for your individual eye condition.
LASIK involves creating a thin flap on the cornea, lifting it, excising the corneal stroma, and then replacing the corneal flap.
In contrast, LASEK involves completely removing the corneal epithelium,
excising the corneal stroma, and waiting for the corneal epithelium to regenerate.
These differences in methods are also the points that differentiate the advantages and disadvantages of LASIK and LASEK.
LASIK, which uses a corneal flap,
offers a relatively faster recovery speed
and less pain.
However, there is a possibility that the corneal flap, which is placed like a lid,
may become dislodged due to external impact.
Therefore, even after vision correction,
you must be careful for a considerable period of time
to avoid external impact.
LASEK requires a longer recovery period for the removed corneal epithelium to regenerate,
and the pain is also quite
severe.
However, once the corneal epithelium has fully recovered,
it becomes almost the same as before,
making it more resistant to external impact and more stable.
As such, LASIK and LASEK have very distinct characteristics,
so it's impossible to definitively say which method
is superior. Instead,
the most suitable method can be selected by considering each patient's lifestyle, occupation,
and eye condition.
"Considering Pain, Recovery Period, and Applicability"
In most cases, people prefer methods with less pain and faster recovery.
LASIK offers less pain and faster recovery,
but it is often difficult to perform in cases of high myopia or thin
corneas.
In such cases, LASEK should be considered.
However, some people hesitate to undergo LASEK due to pain and recovery time.
In these situations, All-Laser LASEK, which meets the requirements for pain, recovery time,
and applicability, may be an option.
All-Laser LASEK uses lasers for the entire process,
allowing for more residual corneal tissue to be preserved.
Therefore, it can be considered by those who have high myopia, astigmatism,
or thin corneas and have difficulty undergoing LASIK or LASEK.
By reducing the irritation to the cornea, the time it takes for the removed
corneal epithelium to regenerate is reduced,
speeding up recovery and
reducing pain afterwards.
In addition, the laser can precisely examine the micro-curvature of the cornea, and
since instruments do not directly touch the eye,
the risk of secondary infection can be reduced.
This helps to prevent potential side effects,
resulting in stable vision correction.
“Two-Day LASEK: Minimizing Corneal Damage”
Among vision correction surgeries, Two-Day LASEK reduces the recovery period and pain burden of conventional
LASEK. One of its characteristics is that it can improve vision while preserving the cornea as much as possible.
This Two-Day LASEK is performed using the Amaris Red equipment.
Instead of alcohol or brushes, a 0.54mm ultra-precision laser is
used to remove the epithelium with approximately 3.5 times higher
precision compared to conventional methods, increasing the recovery speed of the corneal epithelium
and allowing for a faster return to daily life.
In addition, it has an eye-tracking device that reacts in advance even if the eye moves during vision correction surgery,
reducing errors during vision correction. The area stimulated is also
approximately 40% smaller, and it is resistant to external impact.
It also has a system that prevents the laser from overlapping on the areas where it has already been irradiated to reduce heat damage.
It can also lower the risk of various side effects such as dry eye, light scattering, corneal opacity, and myopia regression,
allowing for stable vision correction results.
"Save LASEK: Significantly Reducing Corneal Ablation"
In the past, those with thin corneas or high myopia and astigmatism
often had insufficient residual corneal tissue left during the recovery process, making it difficult to withstand intraocular pressure.
This increased the possibility of problems such as keratoconus, limiting the procedure.
Even if the procedure was performed, caution was required.
Save LASEK uses a precise EX500 excimer laser instead of alcohol or brushes to
accurately remove only the targeted amount of corneal epithelium,
minimizing unnecessary irritation and significantly reducing corneal damage.
This plays a key role in greatly reducing pain and shortening the recovery period for the corneal epithelium to regenerate.
By reducing corneal irritation, it effectively prevents the risk of myopia regression, which is the biggest concern for high myopia and astigmatism,
and allows for stable vision correction results.
In addition, the Save LASEK equipment ablates a smaller amount of cornea under the same conditions, and the accuracy of the results is high.
If the basic requirements are met, it has a wide range of applications that can be applied to high myopia or high astigmatism.
It also reduces the risk of side effects such as nighttime glare or double vision, making it one of the most satisfactory vision correction surgeries.
"Vision Correction Surgery That Determines Lifelong Eye Health and Convenience"
Since satisfaction is higher when you choose the vision correction surgery that is most suitable for your eye condition, it is best to make a decision through thorough
pre-operative precision examination and sufficient consultation.
In addition, it is wise to choose a Seocho-gu eye clinic after checking whether it is equipped with the latest equipment,
conducts thorough eye examinations, has medical staff with skills and experience,
and provides a thorough post-operative care program.
In the past, a score of 1.0 was the standard for successful vision correction, but now it is more important
how long you can maintain clear and comfortable vision.
Aiming to improve the 'quality of vision' rather than simple vision recovery,
we hope you will undergo satisfactory vision correction surgery at a Seocho-gu eye clinic.
Thank you for reading this long article.
This was Lee Min-ji, head director of Gangnam ID Eye Clinic.
