Dr. A.S. Desai :


Welcome to

Carboxymethycellulose sodium (CMC) is one the main medicines of lubricating eye drops . Refresh Celluvisc eye drops contains the same but it is mosre viscous than the other lubricating eye drops. Hence it is often recommended as an additional lubricant for night use for those who need overnight lubrication. If you are uncomfortable using it during day time then it is better to use it once at bedtime. During daytime and waking hours you can use Refresh tears eye drops , 1 drop 4 times a day.Both these medicines are preservative free.

Please feel free to ask follow up questions if any.
