What should you know about iris Q-switch laser?

Q-switched lasers deliver very brief pulses of energy and are commonly discussed for pigment or tattoo targets. The word iris may refer to the coloured part of the eye, an iris-coloured mark, or a clinic's shorthand, so the exact target must be confirmed before treatment. Energy intended for skin should not be assumed suitable for the eye itself.

Ask which tissue is being treated, who will perform the procedure, and what eye protection is required. Share your eye history, medicines, previous laser treatments, tendency to form raised scars, and any active skin or eye irritation. Do not use a consumer laser or permit treatment close to the eye without an in-person examination. A clinician may discuss alternatives such as pigment assessment or [Laser Toning](/treatments/laser-and-energy/laser-toning/), while a [Q-Switched Laser](/technology/q-switched-laser/) page explains the technology more generally.

After any procedure near the eye, seek urgent medical care for new vision changes, severe eye pain, marked light sensitivity, increasing swelling, a chemical sensation, or a wound that is worsening. Blistering, spreading redness, pus, fever, or sudden loss of vision also needs prompt assessment; do not wait for a routine follow-up.

What exactly is the laser targeting, and is an eye specialist involved? What eye shield or other protection will be used? What changes should make me stop treatment and seek help? Which alternatives fit my skin and eye history?
