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.

The Excimer laser is used to reshape the inner layers of the cornea thus changing the eye's power.

Once treated with the Excimer laser, a bandage contact lens is then placed over the cornea to protect the treated area until complete healing of the epithelium.

In Femto-LASIK, the Femtosecond laser is used to create a flap on the cornea. The flap layer is then gently lifted up to expose the inner layers of the cornea.

The Excimer laser is used to reshape the inner layers of the cornea, thus changing the eye's power. Once treated with the Excimer laser, the flap is gently placed back down again in its original position.

A micro-keratome (blade cutter) is used to create a flap on the cornea. The flap layer is then gently lifted up to expose the inner layers of the cornea.

The Excimer laser is used to reshape the inner layers of the cornea, thus changing the eye's power. Once treated with the Excimer laser, the flap is gently placed back down again in its original position.

In SMILE, the Femtosecond laser is used to create a lenticule in the inner layers of the cornea. The Femtosecond laser is able to penetrate the surface of the cornea without any cutting involved or causing any damage to the surface layers.

A small, micro incision (2-4mm) is created at the side of the cornea. The lenticule that was created earlier is gently removed through the small micro incision made. With the lenticule removed, the cornea shape is altered, which changes the power of the eye.
