Why Careful Selection of LASEK Surgery is Important
Hello.
I'm Dr. Lee Min-ji, head director of Gangnam ID Eye Clinic, striving for the healthy eyes of many people every day.
With technology constantly advancing, ophthalmology is one of the medical fields that has seen the most significant progress.
However, with various methods available, undergoing a procedure that isn't well-suited to you can lead to a large burden from side effects or aftereffects and lower satisfaction. Therefore, it's necessary to choose a vision correction method that is suitable for you rather than following the latest trends.
To do this, it's wise to undergo a thorough eye examination for each individual, as everyone's eye condition and circumstances differ, and then choose the appropriate method. It can be helpful to understand the processes and characteristics of LASIK and LASEK surgery and identify their differences.
Today, we'll take the time to learn about LASIK and LASEK surgery, as well as other existing vision correction procedures.
"How do LASIK and LASEK work?"
As more people become interested in vision correction surgery as an alternative to wearing glasses or lenses, they often look into LASIK and LASEK first.
First, the principle of LASIK involves creating a corneal flap, applying a laser to the corneal stroma, and correcting the refractive error.
The advantage of LASIK is that the pain is relatively less and vision recovery is faster because the corneal flap is repositioned after the correction, preventing the laser-treated area from being exposed. However, it is more vulnerable to impact, and LASIK may not be possible for those with thin corneas or high myopia and astigmatism.
LASEK involves removing the outermost layer of the cornea, the epithelium, and using a laser to correct vision by irradiating the corneal stroma according to the refractive error. In the early stages, the corneal surface is exposed, causing severe pain and a somewhat long recovery period, which may make it difficult to decide to undergo the procedure.
However, unlike LASIK, LASEK does not create a corneal flap, making it more resistant to external impact and allowing more residual corneal tissue to remain, which can reduce the risk of potential side effects. As a result, the surgery is more stable, and the rare occurrence of vision regression can also be reduced.
"What if we could find a method that compensates for the disadvantages and enhances the advantages?"
Since the causes of vision deterioration vary from person to person, and the appropriate methods differ accordingly, it's important to find a vision correction procedure that is suitable for you through a thorough eye examination and consultation.
If you have thin corneas or high myopia and astigmatism and are looking for a vision correction procedure that offers minimal pain and rapid recovery, you may want to consider All-Laser LASEK.
All-Laser LASEK performs all procedures with a laser, allowing for a more uniform and consistent corneal ablation, resulting in higher satisfaction with vision correction.
It also reduces unnecessary corneal damage or irritation, which can lower the incidence of various side effects and complications. The procedure time is also shorter, allowing for a more successful vision recovery.
"What is Today LASEK, an upgraded version of conventional vision correction surgery?"
Today LASEK is performed using the Amaris Red excimer laser and involves about 40% less corneal epithelial removal area compared to conventional LASEK. The corneal incision surface is uniform, resulting in relatively less pain, faster recovery, and clearer vision.
The system reduces unnecessary damage to corneal nerves caused by heat, which can lower the possibility of side effects such as myopic regression. The 7-dimensional eye tracker calculates the movement and time of the eye to irradiate the laser, continuously correcting even changes in the angle and position of the eye depending on the posture, accurately correcting astigmatism.
It does not create a corneal flap, making it resistant to external impact and preventing side effects and aftereffects. It is suitable for modern people with thin corneas, high myopia or astigmatism that makes LASIK difficult, or those who lack the time for a longer recovery.
Today LASEK maintains the stability and corneal protection advantages of conventional LASEK while reducing discomfort after vision correction. It is characterized by a relatively short recovery period and excellent vision improvement effects, which is gaining attention.
"What is Save LASEK, an upgraded version of conventional vision correction surgery?"
Save LASEK corrects vision using the EX500 device without a separate epithelial removal process using a brush or alcohol.
It allows for customized correction tailored to the individual's eye condition, reduces optic nerve resection, resulting in less pain and faster recovery. After the corneal epithelium regenerates, it can restore a strong structure like before vision correction, which can be said to be an advantage.
In addition, Save LASEK has a low ablation depth, so it can be performed even in cases of high myopia or astigmatism, or thin corneas, if basic requirements are met. It is resistant to external impact and has less glare and halos, making it suitable for athletes or those with occupations that require nighttime activities.
"How to find the right LASIK or LASEK surgery for you?"
Eye health can deteriorate if neglected, which can significantly reduce the quality of life. If you are considering vision correction surgery due to vision deterioration, you should check the following points.
First, it is necessary to check whether a systematic and precise eye examination is performed thoroughly and delicately.
Because each individual has different eye conditions and characteristics, it is possible to check the individual's eyes and find a suitable method.
Then, it is wiser to check whether the hospital has medical staff with various equipment, skills, and experience, and whether they provide systematic post-operative care before making a decision.
Today, we took the time to learn about various vision correction surgeries, from LASIK and LASEK to All-Laser LASEK. As we live in an era where we can live up to 100 years, and our eyes will be used for a long time, I would like to emphasize choosing the safest vision correction surgery for your eyes.
Thank you for reading the long article. I will come back with more useful content next time. This was Lee Min-ji, head director of Gangnam ID Eye Clinic.
