LASEK eye surgery, which stands for laser epithelial keratomilieusis, is very similar to LASIK, PRK, and other laser eye surgery methods. The one major difference is that the outer layer of the cornea remains intact, rather than being removed with the laser, as in PRK. LASEK is often considered one variation of PRK because of the methods used to correct eye issues.
The first step of LASEK eye surgery is the removing of the outer layer of the eye, known as the epithelial layer, to allow the eye surgeon access to the underlying cornea. During this eye surgery method, a cutting tool known as a trephine is used to remove this layer of the eye. A diluted alcohol solution is used to loosed the epithelium, making it easier to remove. Like with all laser eye surgeries, an anesthesia in the form of eye drops is used to numb the area before the procedure begins.
During LASEK eye surgery, the laser energy is used to reshape the outer surface of the eye, correcting the patient’s vision. Once the laser procedure is complete, the epithelial flap is placed back over the eye, where it adheres to the cornea automatically. No stitches are required.
LASEK is often the recommended refractive surgery method for those whose cornea is too thin for other laser procedures. The chance of complications is lower than those associated with either LASIK or PRK. LASEK creates a much thinner flap than the one created using the LASIK method, making it ideal for those who have an overly thin cornea. It is also recommended for those who have large pupils, which make them poor candidates for LASIK surgery.
Unlike with PRK, the outer surface of the eye remains intact, reducing the recovery time. Although the healing time with LASEK is longer than the LASIK recovery time, LASEK typically comes with a reduced risk of complications.
