Q: Does LASIK surgery change your eye color?

A: The iris is the colored portion of the eye. Normally the color of the iris does not change after Lasik, however a change in iris color may indicate other ocular health issues that should be checked. Depigmentation of the iris may make it become lighter. Some medications may cause iris hyperpigmentation in certain races that will make the iris darker. Lasik won’t make brown eyes blue and anyone who experiences a sudden change in iris color should be examined by an eye doctor immediately.

A very (very) few Lasik patients have reported a change in the perception of colors after Lasik. A slight color shift toward the red spectrum is extremely rare. This effect is not like a filter or color blindness, but is likely due to a change in the frequency of light passing through the cornea that has been altered by laser eye surgery.
