LASEK (LASER-ASSISTED SUBEPITHELIAL KERATECTOMY)
LASEK is a laser vision correction procedure that reshapes the cornea to improve vision. Unlike LASIK, LASEK preserves the outer layer of the cornea instead of creating a deeper flap. As a result, it suits patients with thinner corneas or those at higher risk for flap-related issues. Therefore, patients can achieve clearer vision with a surface-based approach.
WHAT THIS SERVICE TREATS
LASEK corrects refractive errors that cause blurred vision. These include nearsightedness, farsightedness, and astigmatism. Because these conditions affect how light focuses on the retina, patients often experience difficulty with daily tasks. Therefore, reshaping the cornea improves focus and visual clarity.
HOW THE PROCEDURE WORKS
First, the surgeon applies anesthetic drops to keep the eye comfortable. Next, the surgeon gently loosens the thin outer layer of the cornea. Then, an excimer laser reshapes the corneal surface according to a personalized plan. After that, the surgeon repositions the surface layer and places a protective contact lens. As a result, the eye begins to heal while vision gradually improves.
WHO MAY BENEFIT
LASEK may benefit patients who are not ideal candidates for LASIK. For example, individuals with thin corneas or active lifestyles may prefer a surface procedure. In addition, patients who want to avoid a corneal flap may consider this option. Therefore, LASEK offers an alternative for safe and effective vision correction.
RECOVERY AND EXPECTED OUTCOMES
Recovery after LASEK takes longer than LASIK. Patients may experience mild discomfort, light sensitivity, and blurred vision during the first few days. However, vision gradually improves over several weeks. Because healing occurs at the surface, careful follow-up and medication use support recovery. As a result, patients achieve stable visual outcomes over time.
SAFETY AND CLINICAL CONSIDERATIONS
The surgeon performs LASEK after detailed screening and measurements. In addition, the doctor evaluates corneal thickness, shape, and eye health. While LASEK has a strong safety profile, risks may include dry eye, haze, glare, or infection. Therefore, proper patient selection and follow-up care remain essential.
