LASEK vs LASIK

Many Similarities but LASEK is Safer and Creates Less Dry Eye than LASIK

LASEK

LASIK

Procedure

Outer layer of the eye (the epithelial cells) is gently lifted and folded over using a mild alcohol solution to loosen the cells. Laser energy is applied to reshape the cornea, the cell layer is repositioned and a soft contact lens is placed over the eye to help keep the cells in place while it heals (about 3 to 4 days).
Procedure

Corneal flap is created using a microkeratome knife and laser energy applied to reshape the cornea. After the laser has reshaped the cornea, the corneal flap is repositioned over the cornea.
Advantages

No cut is made. No flap is made. This means you will NEVER experience any flap complications with LASEK. On a pure safety level, this is a very comforting advantage over LASIK. There’s also less chance of developing dry eye and it can be performed more than once.
Advantages

LASIK results are almost immediate. Recovery time is slightly shorter than LASEK. Within 24 hours, 99% of patients see 20/40 or better, while 70% see 20/20 or better.
Disadvantages

The only real slight disadvantages are time-related. You must wear a bandage contact lens for the first 3 to 4 days after surgery. This enables the epithelial cell layer that was dissolved to grow back and heal naturally. Also, the healing response and visual stability restoration period is a tad longer -- about 4 days versus LASIK's 1 to 2 days. The “wow” effect will happen!
Disadvantages

A cut is made to create the corneal flap. Though rare, there are complications associated with the making of a flap, including, but not limited to, dry eye infection, flap wrinkles that can cause visual distortion or double vision, epithelial ingrowth, and the chance of the flap being knocked loose by an accidental bump or other trauma. The flap alone makes LASIK a riskier choice now and in the future.
Overall

Safer, safer, safer – no cut, no flap complications -- ever. LASEK is best suited for everyone – especially those with thinner corneas, higher levels of prescription, and larger pupils. Same visual acuity results as LASIK with slightly longer recovery period. Dr. Yee will be the first to tell you -- what’s an extra couple of days of healing when it comes to the health of your vision?
Overall

LASIK has an almost immediate ‘wow’ effect, the recovery time is shorter than LASEK and it is virtually painless – however, the inherent risks associated with the making of the corneal flap make it a riskier procedure both in the short and long run.
