Polyacrylic Acid (Viscotears® Liquid Gel) and Sodium Carboxymethylcellulose (Tearsoft® Eye Drops)

On a recent trip to Bogota I was advised by a local optician to take eye drops throughout the day. The eye drops prescribed were Procaps' Tearsoft eye drops. Their active ingredient being Carboximetilcelulosa Sódica, that translates to Sodium Carboxymethylcellulose (or also known as carmellose sodium, a lubricant that reduces water loss) in English at 5,0 mg. Product information can be found on their official page here. But otherwise here's their contact information: Barranquilla, Calle 80 No. 78B - 201, Tels: +5753530783 - +5753530090 Bogotá, Carrera, 15 No. 106 - 65 Pisoa 6 y 7 Edificio Colpatria, Tels: +5715230123 - +5715230130 Product Website.

In the UK it's hard to find a brand of eye drops that use the same active ingredient as Tearsoft. The one that I know of is called Optive by a company called Allergan registered as Allergan Limited, 1st Floor, Marlow International, The Parkway, Marlow, Bucks, SL7 1YL. The website showing their two eye drop products is here.

Otherwise, a near match is Vistotears by Alcon Laboratories (U.K) Limited. More info can be found at this website. The active ingredient being Polyacrylic Acid is a suitable alternative to Sodium Carboxymethylcellulose but as a gel. There are a few videos on YouTube that mention Viscotears but really only for cosmetic reasons. The first video is here and the next can be found here.

    The carbomer component is found beneficial by many patients but unfortunately difficult to get in the US, although there are a number of thicker drops or gels such as Systane Ultra and Genteal gel.

  3. Thanks for the comment and thank you for suggesting alternatives.
