Which ointment to choose? There are lots of ointments on the market, and they're all made of the same stuff mostly - white petrolatum and mineral oil. The main thing that distinguishes one product from another is the proportions of those two ingredients. Genteal and Systane ointments are mostly white petrolatum (94%) and only 3% mineral oil. For plenty of people the differences may not matter, but certainly I've noticed some over the years who find that the differences matter for their purposes, so comparison shopping can be helpful.
Should I be using ointment at all? Ointments are attractive for overnight use due to their staying power - unlike polymer drops and gel drops, they don't just dissolve and dissipate in a short time. However, not everyone who has moderate to severe overnight dry eye symptoms therefore has to use an ointment. Many people can get by with a less viscous (not to mention non-greasy!) lubricant, such as a polymer gel or even gel drop, if they also use some kind of night protection (shield, mask, goggle, etc.).
GenTeal Night-time PM ointment provides long-lasting relief for night-time comfort.
