We think it’s vital to see the world clearly for a better life. Choosing the right vision correction is a big decision. We offer the medical expertise you need, with care and compassion.
Lasek surgery is a top pick for many. It uses lasers to reshape the cornea and fix vision problems. We’re proud to give world-class healthcare to people everywhere.
Key Takeaways
- Both procedures use specialized lasers to treat nearsightedness and astigmatism.
- LASEK is better for those with thinner corneas.
- LASIK often means a quicker recovery for most.
- We follow the latest medical standards for the best vision.
- Our care supports health seekers from around the world.
Understanding LASEK Surgery and Its Procedure
LASEK, or laser-assisted subepithelial keratectomy, is a modern way to fix vision problems. It’s a detailed process that reshapes the cornea. We’ll dive into what LASEK surgery is and how it’s done.
LASEK is a laser eye surgery that changes the cornea’s shape to correct vision. It’s like PRK but uses an excimer laser. Unlike LASIK, it doesn’t need to cut the cornea.
What is the laser eye surgery definition for LASEK?
LASEK reshapes the cornea with an excimer laser to fix vision issues. It loosens the outer cornea layer with ethanol, then reshapes the inner layer with the laser.
Medical Expert, a well-known eye doctor, says, “LASEK is great for people with thin corneas or those who might face LASIK risks.”

What happens during laser eye surgery of the LASEK variety?
LASEK starts with eye drops to numb the eye. Then, an ethanol solution loosens the outer cornea layer. This makes it easy to move aside.
The excimer laser then reshapes the cornea based on the patient’s needs. This part of the surgery is quick, taking just a few minutes per eye.
After reshaping, the outer layer is put back. A bandage contact lens is used to help the eye heal.
Comparing LASEK Surgery to LASIK
When you think about laser eye surgery, knowing the difference between LASEK and LASIK is key. Both change the shape of the cornea to fix vision. But they do it in different ways.
Key differences in corrective laser eye surgery techniques
The main difference is how they get to the corneal tissue. LASIK makes a thin flap in the cornea. This flap is gently lifted to show the tissue underneath. LASEK, on the other hand, loosens and lifts the outer layer of the cornea, called the epithelium.
LASIK is good for people with thicker corneas because it lets them see better faster. LASEK is better for those with thinner corneas or who might get hurt in the eye.
Evaluating the cons of laser eye surgery and possible drawbacks
Both LASIK and LASEK are effective, but they have their downsides. LASIK might cause dry eye or flap problems. LASEK might make you feel more pain and take longer to heal.
It’s important to know the disadvantages of laser eye surgery before you decide. You might worry about not seeing well enough, getting an infection, or seeing halos or glare.
- Potential for dry eye
- Risk of infection
- Visual disturbances
- Undercorrection or overcorrection
Conclusion
When you think about fixing your vision, knowing the difference between LASEK and LASIK is key. Both can fix your vision, but the right choice depends on your eyes and what you prefer.
We’ve looked at the main differences between these two surgeries. We talked about their good points and things to watch out for. People often wonder how long LASEK lasts, which is a big question for those thinking about it.
Talking to an eye doctor is the first step to figure out what’s best for you. They can help decide if LASEK or LASIK is better for you. They’ll look at your eye exam and other important details.
Knowing the details about LASEK and LASIK helps you make a smart choice for your vision care.
FAQ
What is the medical laser eye surgery definition for LASEK?
LASEK is a type of laser eye surgery where the thin outer layer of the cornea (epithelium) is loosened, lifted, and the underlying cornea reshaped with a laser to correct vision.
What happens during laser eye surgery of the LASEK variety?
During LASEK, the surgeon loosens the corneal epithelium with alcohol, applies an excimer laser to reshape the cornea, and then repositions the epithelium to heal naturally.
What is LASIK surgery used to treat compared to LASEK?
Both LASIK and LASEK correct myopia, hyperopia, and astigmatism, but LASIK involves creating a deeper corneal flap for faster recovery, whereas LASEK is preferred for thinner corneas or patients at higher risk of flap complications.
How long does LASEK last and are the results permanent?
The vision correction from LASEK is typically permanent, though small changes may occur over years due to natural aging of the eyes.
What are the primary cons of laser eye surgery and LASEK?
Cons include longer recovery compared to LASIK, temporary blurred vision, light sensitivity, dry eyes, halos or glare, and small risks of infection or regression of vision.
Should I expect significant laser eye surgery pain afterwards?
LASEK recovery can involve mild to moderate discomfort for a few days, including stinging, burning, or light sensitivity, which is usually managed with prescribed drops and pain relief.
What is laser eye surgery like for the patient during the procedure?
Patients are awake, with numbing drops applied; the laser reshaping is quick, painless, and often feels like pressure or mild scraping on the eye.
Is LASEK the last eye treatment I will ever need?
While LASEK permanently corrects refractive errors, age-related changes like presbyopia or cataracts may still require glasses, contact lenses, or additional procedures later.
