This new keratome enables us to cut a very thin flap from the front surface of the eye. The stroma is the thickest part of the stroma. A very thin layer of the cornea is removed with the Excimer Laser machine. This thickness represents more or less two thirds the thickness of a human hair. This change in the thickness of the cornea leads to the change in the curvature of the eye.
Light rays are now focused on the retina.
The cap is then replaced on its bed and treated, so that it adheres tightly to the underlying layers without the need for any sutures. The Lasik procedure is therefore a combination operation, during which a thin layer of the cornea is partially removed. This is then followed by Excimer Laser treatment on the stroma. All the different layers of the cornea are thus maintained and the normal anatomical structure of the cornea is kept in tact. This prevents the development and scar tissue formation.
