  advanced laser eye surgery discovered ever.

• Step-I Placement of the suction ring is done
  over eyes cornea.
• Step-II A partial flap even uniform thickness is
  made by the microkeratome in cornea.
• Step-III Corneal flap is held back on its hinge
  to expose the central portion only.
• Step-IV Tissues are removed by the excimer laser
  for reshaping the cornea.
• Step-V The hinged corneal flap is brought back
  to its own position.
