What Retaine Is
Retaine is a preservative-free dry eye line from OCuSOFT. Retaine CMC is a microemulsion drop, which means tiny droplets help hold both the water and oil parts of the tear film on the surface of the eye, and it comes in single-use vials. Retaine PM is a preservative-free nighttime ointment for stronger or overnight dryness. Because the line is preservative-free, it suits sensitive eyes and frequent dosing.

Dry Eye Rescue Tip
Ointments are thicker and can blur vision briefly, so the Retaine PM ointment is best at bedtime, with the CMC drops used during the day.
