Occasionally used for mild to moderate degrees of keratoconus in contact lens intolerant patients. The cornea needs to have adequate thickness and no scarring. Rarely for mild degrees of nearsightedness.
INTACS are small arcs of plastic that can be implanted deep in the cornea around the pupil to induce corneal flattening. The incisions can be made with a blade but the incisions are most commonly fashioned with a femtosecond laser. INTACS surgery is performed under topical anesthesia in the Laser Suite and/or the operating room.
