LASEK Eye Surgery

​​​​​​​

What Is LASEK?

LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is a type of laser eye surgery used to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

It reshapes the cornea—the clear front surface of the eye—so that light focuses properly on the retina, improving vision.

LASEK is similar to LASIK and PRK, but it is often recommended for people who have thin corneas or dry eyes, where LASIK may not be ideal.

How to Prepare for LASEK Eye Surgery

Preparing properly helps ensure a smooth procedure and recovery. Common preparation steps include:

• Eye examination: Your eye doctor will perform detailed tests to check your vision, cornea thickness, and overall eye health.

• Stop wearing contact lenses: You may need to stop wearing soft lenses a few days before surgery and hard lenses several weeks before, as they can change the shape of your cornea.

• Avoid eye makeup and creams: On the day of surgery, keep your face clean and free of makeup, lotions, or perfumes.

• Arrange transportation: You won’t be able to drive immediately after the procedure.

• Follow your doctor’s instructions: This may include using prescribed eye drops before surgery.

What Happens During LASEK Eye Surgery?

LASEK is usually quick and done on an outpatient basis.

• Numbing eye drops are applied so you won’t feel pain.

• A thin layer of the cornea’s outer surface (the epithelium) is gently loosened and moved aside.

• A laser reshapes the cornea to correct your vision.

• The epithelial layer is placed back into position.

• A soft contact lens is placed on the eye to protect it during healing.

The procedure typically takes about 10–15 minutes per eye.

What to Expect After LASEK Eye Surgery

Recovery from LASEK takes longer than LASIK, but the results are long-lasting.

• First few days: You may experience mild discomfort, light sensitivity, or blurry vision.

• Healing period: The protective contact lens is usually removed after several days once the surface has healed.

• Vision improvement: Vision improves gradually over days to weeks.

• Follow-up visits: Your doctor will monitor healing and vision progress.

• Activity limits: You may need to avoid swimming, rubbing your eyes, and strenuous activities for a short time.

Most people can return to school or light activities within a few days.

What Are the Advantages of LASEK Eye Surgery?

LASEK offers several benefits, including:

• Suitable for thin corneas: A good option for patients who cannot have LASIK.

• Lower risk of flap complications: Since no deep corneal flap is created.

• Effective vision correction: Long-term improvement in vision.

• Less corneal weakening: Compared to LASIK.

• Permanent results: For most patients, vision correction is long-lasting.
