LASIK for High Myopia: Exploring Today's LASEK Options
If you're looking into LASEK methods for high myopia...
Hello.
I'm Kim Joong-hoon, head director of Gangnam ID Eye Clinic.
I'd like to greet you.
These days, more and more people are concerned about vision problems.
When I conduct consultations, I see a steady increase in the number of people, regardless of age,
who experience discomfort due to myopia and astigmatism.
Many people with poor eyesight correct their vision with glasses or
contact lenses. However, due to the various inconveniences that can arise from these corrective tools,
more and more people are considering vision correction surgery.
Since vision correction surgery is performed on a sensitive area of the body, the eyes,
it's important to apply a method that is appropriate for the individual's eye condition to maximize the corrective effect.
However, not everyone with poor eyesight can undergo the same type of laser vision correction surgery to correct their vision.
In particular, for eyes with severe myopia or astigmatism, there are many more factors to consider during correction.
Today, we'll analyze the limitations of existing vision correction surgeries and compare
the most suitable methods for high myopia LASEK all at once.
"What are the structural limitations of existing LASIK and LASEK?"
LASIK and LASEK are similar in that they correct refractive errors by applying a laser to the corneal stroma.
However, they differ in how the stromal area is exposed to apply the laser.
It's difficult to say which method is better, and each has its own characteristics, advantages, and disadvantages.
Therefore, it's necessary to comprehensively consider one's vision, corneal thickness, and other factors to choose the most appropriate method.
LASIK involves cutting the cornea, including the epithelium and part of the stroma, to a specific thickness to create a corneal flap.
Then, a laser is applied to the corneal stroma, and the flap is repositioned. This method is less painful
and has a shorter recovery period.
Most modern people prefer LASIK because it is less painful and has a faster recovery.
However, LASIK requires cutting the cornea by more than 20mm to create the corneal flap.
If the cornea is thin or there is high myopia and astigmatism,
it may be difficult to secure a safe corneal thickness, which may limit the procedure.
LASEK corrects vision by removing the corneal epithelium, exposing the corneal stroma, and then applying a laser.
Since the amount of tissue removed is small, it can be performed even on patients with thin corneas or moderate to severe myopia.
It is more resistant to external impact, but it is more painful
and requires a longer recovery period, so many people hesitate before undergoing the procedure.
In cases of high myopia or higher, if the safe residual corneal
thickness standard is not met, the possibility of side effects and
aftereffects was high, and if it was performed recklessly, problems could occur, so
we could recommend proceeding with all-laser LASEK.
"The Emergence of All-Laser LASEK"
All-laser LASEK is performed using only a laser, without the use of any tools.
It can reduce damage and irritation to the cornea,
which virtually eliminates the aftereffects such as dry eye and corneal haze that could occur afterward.
It also allows for safe and rapid recovery because it enables precise cutting of the corneal epithelium.
Because the amount of tissue removed and pain were reduced,
it was a method that could be chosen by those who had severe high myopia or astigmatism
and had difficulty undergoing general vision correction surgery.
In addition, by reducing the area of the corneal epithelium that is peeled off,
inflammation, pain, corneal opacity, and
myopia recurrence could be prevented, and subsequent
satisfaction was high.
"Today LASEK, Evolving and Becoming More Precise"
Today LASEK does not create a corneal flap
and delicately corrects the surface layer, so
it is famous as a method to reduce the risk of corneal damage, pain, and recovery period.
It is difficult to take a leave of absence or
for those who have difficulty adjusting their schedules, it is being evaluated as one of the realistic alternatives for vision correction.
Today LASEK is performed with the Amaris Red 1050RS
laser equipment, and it proceeds in one step from epithelium removal to
correction, accurately cutting only the necessary
parts of the corneal epithelium and stroma at the same time to correct vision.
In addition, the diameter of the laser beam is very small,
which can reduce damage to the corneal epithelium.
During vision correction,
the 7-dimensional eye tracking system tracks even the slightest movements of the eye in real time.
By compensating, accuracy and safety have been further improved.
Through this process, the wound area can be reduced by about 40%.
It can also be selected in cases where LASIK is difficult due to thin corneas or corneal diseases.
It was also the reason why it is evaluated as LASEK for high myopia suitable for those planning to enlist in the military and sports enthusiasts who enjoy intense activities.
"Save LASEK, Enabling Wider Vision Correction"
Save LASEK uses EX500 White laser equipment and
VARIO corneal topography analysis equipment.
The main feature is that the amount of tissue removed is small, so it is possible to correct high myopia and high astigmatism.
After removing the corneal epithelium using the EX500 White's laser corneal epithelium removal
mode, the laser is immediately
proceeded to laser vision correction mode through the transmitted data.
All-laser one-step corneal cutting reduces pain,
recovery period, and the possibility of regression, making it a highly satisfactory method.
In addition, the degree to which the eyeball rotates in real time is
confirmed through the change in position of the cross axis in the microscope.
EX500 tracks the eyeball rotation phenomenon in real time and then
corrects the astigmatism axis.
Therefore, the % value of the laser being irradiated can be
confirmed with a microscope, so it was possible to confirm that the laser irradiation was safely completed,
and by increasing the laser shot in the periphery by 15~20%,
it was possible to reduce light scattering even in situations where the pupil dilates.
“High Myopia LASEK That Needs to Be Investigated More Thoroughly”
Even if there is a desired method, the possibility of high myopia LASEK may
vary depending on the condition or status of the eye, so through precise examination and consultation,
it was important to correct vision in a way that reduces concerns about side effects.
In cases of high myopia or a history of past eye diseases,
a more thorough examination than usual was required. Corneal thickness, intraocular pressure,
After comprehensively evaluating vision status and pre-existing eye diseases, it was desirable to create a plan tailored to each individual.
Check whether a thorough eye examination is being conducted
Whether the latest equipment is being used, abundant experience and
Whether there are medical staff with high skills stationed,
Whether it has a systematic system and provides detailed
It was wise to check the overall aftercare before proceeding.
With the development of technology, there are many methods that can be tried even in cases where general vision correction surgery is difficult.
I hope you will proceed with the right high myopia LASEK that can affect the quality of your vision and eye health.
Thank you for reading this long article. This was Kim Joong-hoon, head director of Gangnam ID Eye Clinic.
