LASIK eye surgery
What is meant by LASIK eye surgery?
LASIK is the abbreviated form of Laser-
Assisted In Situ Keratomileusis which 
adjusts the cornea shape permanently. It 
is done with the help of excimer laser 
and is regarded as the most advanced 
laser eye surgery discovered ever. 
The methods to perform 
LASIK eye surgery?
• Step-I: Placement of the suction ring is done over eye’s 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. 
Potential Risks
• No availability of long-term correction
• Eyeglasses may need after surgery as well for some 
patients
• A pale chance of complete vision loss is also there
• Debilitated visual symptoms can be there too
• Severe dry eye symptoms can emerge 
• Impact of the outcome may get faded out with time for 
hyperopia patients
LASIK is not suitable if-
• You have any long-term disease or taking any medication 
which can interfere with recovery.
• You have changed the prescription glasses and contact 
lenses last year. It mainly occurs due to refractive 
instability.
• You participate in sports actively such as martial arts, 
wrestling and boxing in which there is a chance to 
receive direct blow on face and eyes.
