PRK v/s Bladeless Lasik1. Procedure

• PRK

• Bladeless Lasik

• PRK is a procedure of eye surgery, wherein
  numbing eye drops are applied in the eyes of the
  patient.
• In the next step, the top layer of cornea- also
  known as the epithelium is removed cautiously.
• Finally, an excimer laser is used to reshape the
  cornea and hence the vision is corrected.

• A suction ring is placed on the eye to keep eyes
  still after using the drops for maintaining
  numbness.
• A Femto-second laser device is used in this
  surgery to make a thin cut in the cornea, after
  which it is reshaped with the help of a laser.
• As a final step, the thin flap is folded back to
  its original place.

Note Both the procedures are pretty much
similar in the sense that both the procedures
make use of lasers to reshape the cornea to get
perfect vision. However, the difference lies in
the fact that in PRK- the top layer of cornea is
removed entirely. While, on the other hand, in
Bladeless Lasik, a flap is created on the cornea
which is then folded back to its original place
once the procedure is done.

2. Recovery

• PRK

• Bladeless Lasik

• In Lasik Eye Surgery, recovery is very quick.
• The patient is able to see more clearly than
  before from the very next day of the surgery.
• No bandage is required after the surgery.
• Not much pain or discomfort is experienced. In
  rare cases, burning sensation may be felt but it
  doesnt lasts longer than a hour.
• In case of any slight discomfort or irritation in
  the eye, Lasik Surgery Specialists recommend
  lubricating drops to ease the healing process.

• Contact like bandages are applied on the affected
  eye to help the eyes recover from surgery.
• This can cause irritation and sensitivity in the
  eyes due to light until the bandages are removed.
• Some people may experience blurry vision for some
  time.
• However, once the eyes recover and bandage is
  removed, you will achieve the desired vision.

Which Surgery is more Effective?

• The bottom line is that both the surgeries (PRK
  and Bladeless Lasik) are effective in correcting
  the vision permanently. The main difference is
  that it takes lesser time to recover after
  undergoing Bladeless Lasik while it can take over
  a month to recover after PRK surgery.
• However, it is always advisable to vision your
  ophthalmologist and have a comprehensive eye
  examination before deciding which surgery to go
  for. You surgeon may best recommend you which
  surgery best fits your needs.
