Advanced Surface Ablation (ASA)

Advanced Surface Ablation Malaysia


  1. In ASA, the top skin layer of the cornea (the epithelium) is gently removed to allow the Excimer laser to be applied to the inner layers of the cornea.
  2. The Excimer laser is used to reshape the inner layers of the cornea, thus changing the eye’s power.
  3. Once treated with the Excimer laser, a bandage contact lens is then placed over the cornea to protect the treated area.

Recommended for those who:

  • Require an alternative to Femto-LASIK or SMILE
  • Have thinner corneas
  • Have a scar on the cornea (due to previous eye infection or injuries)
