What Is LASIK? How Does It Works?

LASIK is also known as Laser-assisted in Situ Keratomileusis. It is a laser procedure designed to use a laser underneath a corneal flap (in situ) to reshape the cornea (keratomileusis), so that it changes the focal point of the eye. Ideally, the focal point is changed so that it focuses perfectly on the retina, just like a normal eye. LASIK is a type of refractive surgery used to treat common vision problems such as astigmatism, nearsightedness, and farsightedness.

Step 1 : Create Ultra-thin Flap On The Surface Of Cornea


Your eye will be immobilized so that it can not move during the procedure.

The new technology of Intra-laser LASIK that 80% of clinics have adopted is LASIK flaps cut with a laser. It mean a safer surgery as the results are more accurate, so fewer enhancements needed, and the eye is left stronger. Then a flap is created in the cornea, and is gently lifted up.

The standard technology use an instrument called a keratome, It is attached to a suction ring, which allows a very precise incision. The keratome unctions like a carpenter's plane, seperating a very thin layer off of the front of the cornea. Then a flap is created in the cornea, and is gently lifted up.

Step 2 : The Cornea Is Reshaped For Improved Vision


By folding this flap of tissue back, the surgeon is able to use an excimer laser to remove tiny pieces of the corneal tissue until the cornea is shaped just right.


Step 3 : The Flap Is Laid Back Into Place, And Immediately Begins Healing

After the treatment is completed, the flap is replaced and allowed to dry into position. Very little healing is involved, since the flap seals itself into position very quickly.
