Which treatment option is best between LASIK and LASEK for eye correction?

  • October 24, 2020


LASIK and LASEK are both laser eye corrective surgical treatment which helps to treat farsightedness, nearsightedness, and astigmatism. In both of the options, an excimer laser is used and the surgery is performed to reshape & ablate the cornea part to correct the vision problem. In this blog, we will discuss both the lasek and Lasik eye surgery for your understanding.

What is LASIK eye surgery?

LASIK is the most common refractive surgery and the most successful option. Its healing time is short and you can go back to your normal working routine in one day or 2. Studies have shown that most of the patients are satisfied with their results. During LASIK corneal flap is created with the femtosecond laser. The flap will reseal itself within 24 hours and the vision gets betted in a few hours to a day. LASIK healing time is faster as compared to LASEK

What is LASEK eye surgery?

During the LASEK procedure, the top layer of the cornea is reattached, moved, and loosened. The regeneration is done within 3 to 5 days. In between that time, it is common to have discomfort and it will take time to clear the vision with LASEK as compared to LASIK.

LASEK is a preferable option if you have a thin cornea and it does not need as much tissue as LASIK does.

How to select between LASIK and LASEK?

Pros of LASIK:

  • Healing time is 24 hours, with vision often clearing within a few hours of surgery.
  • Vision is regularly 20/40 or gets better following surgery.
  • This procedure is minimally invasive.
  • Discomfort is minor, with any pain dissipating quickly.
  • It has fewer complications

Cons of LASIK:

  • Dry eyes are common with this surgery.
  • With this surgical procedure, corneal flap complications can occur.
  • The flap can become dislodged if bumped or in the event of head trauma before healing is completed.

Pros of LASEK:

  • This surgical procedure is beneficial for thin corneas.
  • Dry eyes are less common.
  • With this surgery, the risk of removal of the outer cornea in excess and corneal flap issue is not present.
  • Vision can become 20/40 or better following the surgery.

Cons of LASEK:

  • LASEK healing time is more as compared to other procedures. It needs around 3 to 5 days for healing and improving the vision.
  • It has a longer healing time of three to five days, and it can take longer for vision to clear.
  • Pain and discomfort can be there for a few days.
  • There is a risk for compromised corneal structure, and it leads to haze.
