Lasik Eye SurgeryLASIK is performed in two steps. The first step is to create a flap of corneal tissue. A corneal suction ring is applied to the eye, holding _____ eye in place. The step in the procedure can sometimes cause small blood vessels to burst, resulting in bleeding ______ subconjunctival hemorrhage into the white of the eye, a harmless side effect that resolves within several weeks. Increased suction typically causes _______ transient dimming of vision in the treated eye. Once the eye _______ immobilized, the flap is created. This process is achieved with a mechanical microkeratome using a metal blade, or __________ femtosecond laser microkeratome (procedure known as IntraLASIK) that creates a series of tiny closely arranged bubbles within the cornea. A hinge _________ left at one end of this flap. The flap is folded back, revealing the stroma, the middle section of the cornea. The process _________ lifting and folding back the flap can be uncomfortable. The second step of the procedure is to use an excimer laser to remodel _________ corneal stroma. The laser vaporizes tissue in a finely controlled manner without damaging adjacent stroma by releasing the molecular bonds that hold the cells together. No burning with heat or actual cutting is required to ablate the tissue. The layers of tissue removed are tens of micrometers thick. Performing the laser ablation in _________ deeper corneal stroma typically provides for more rapid visual recovery and less pain. |
