- Laser context
- Q-switched pigment lasers have the longest track record; picosecond 755 nm and 1064 nm approaches also have published evidence.
- Course
- A series rather than a single session; no universal session number.
When pigment extends beyond the skin. Nevus of Ota can involve the eye. A cosmetic laser session treats selected skin pigment; it does not assess or treat ocular involvement. Tell us about any pigment in the white of the eye, visual symptoms or previous eye follow-up, as an ophthalmic assessment may be advised.
