What is the Lasek procedure?
Imagine a 40-year-old woman named Emily who has been wearing glasses since she was in high school. She struggles with her vision, often experiencing difficulty reading small print and recognizing faces from a distance. Frustrated by these limitations, Emily decides to explore alternative options for improving her eyesight. One option that catches her attention is the Lasek procedure.
The Lasek procedure, short for Laser Epithelial Keratomileusis, is a type of laser eye surgery commonly used to correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Unlike other forms of laser eye surgery like LASIK or PRK, Lasek involves gently lifting a thin layer of tissue from the cornea’s surface rather than creating a flap. This makes it an ideal choice for individuals with thinner corneas or those at higher risk of certain complications.
To better understand the Lasek procedure, let’s delve into its key characteristics:
- Anesthetic: Before the surgery begins, numbing eye drops are administered to ensure patient comfort throughout the procedure.
- Flap creation: Using an alcohol-based solution, the surgeon carefully lifts and separates the epithelial layer from the underlying stromal bed.
- Corneal reshaping: A cool ultraviolet excimer laser beam is then applied to reshape the exposed cornea based on individual prescription requirements.
- Bandage contact lens: Following completion of the laser treatment, a soft bandage contact lens is placed over the treated area to protect it during healing.
By considering these aspects of the Lasek procedure, patients can gain insight into what they can expect before undergoing this innovative surgical technique. In subsequent sections, we will explore additional benefits associated with choosing this particular form of laser eye surgery and how it compares to other available options.

Comparing Lasek with other laser eye surgeries
Section: Comparing Lasek with other laser eye surgeries
In comparing the Lasek procedure with other laser eye surgeries, it is important to consider various factors such as effectiveness, recovery time, and potential risks. To illustrate this comparison, let’s take a hypothetical example of two patients who are considering different laser eye surgery options.
Patient A opts for LASIK (Laser-Assisted In Situ Keratomileusis), a popular choice due to its quick recovery time and high success rate. After undergoing the procedure, Patient A experiences minimal discomfort during the healing process, allowing them to return to their daily activities within a few days. The LASIK procedure involves creating a flap in the cornea using either a microkeratome or a femtosecond laser before reshaping the underlying tissue with an excimer laser.
On the other hand, Patient B chooses the Lasek procedure. Unlike LASIK, Lasek does not involve creating a corneal flap but instead uses alcohol solution to loosen the outermost layer of cells called epithelium. Once loosened, these cells are gently moved aside before reshaping the cornea using an excimer laser. This technique is particularly suitable for patients with thin corneas or those involved in contact sports where there is a risk of trauma to the eyes.
When comparing these two procedures along several key aspects:
- Effectiveness: Both LASIK and Lasek have been proven effective in correcting refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
- Recovery Time: While LASIK offers quicker visual recovery compared to Lasek, which usually requires longer healing time due to epithelial regrowth after removal.
- Potential Risks: Although both procedures carry some risks such as dry eyes or infection, complications like flap-related issues are more common in LASIK, while Lasek is associated with a higher chance of experiencing discomfort during the healing process.
To summarize, choosing between LASIK and Lasek requires careful consideration of individual circumstances and preferences. While LASIK may provide faster recovery time, Lasek could be a suitable alternative for patients with specific requirements or concerns about the creation of a corneal flap. It is crucial to consult with an experienced ophthalmologist who can guide patients in making an informed decision based on their unique situation.
Now let’s continue exploring other aspects related to laser eye surgery in subsequent sections.
