Possibility of corneal damage due to dry eyes...Dong-A Pharmaceutical presents customized artificial tears IO Coolin PDRN eye drops

May 15, 2025

Continued dry eye is likely to dry the corneal surface, causing corneal injuries. Frequent wearing of contact lenses can also cause fine wounds to the eyeball due to lenses or foreign substances. If micro-damage is repeated in the eyeball, the wound can deepen, causing vision loss, and damage to corneal and conjunctival epithelial cells can pose a threat to eye health due to poor adhesion to the eyeball surface.

Possibility of corneal damage due to dry eyes...Dong-A Pharmaceutical presents customized artificial tears IO Coolin PDRN eye drops



In this regard, Dong-A Pharmaceutical's customized artificial tear brand IOCool will introduce a new "IOCool New PDRN Eye drops".

The main component of the Iochuline PDRN eye solution is polydeoxyribonucleotide sodium (PDRN), which is a DNA fragment extracted from salmon testis and has effects such as tissue recovery, anti-inflammatory activity, and can help promote regeneration of damaged cells.




Iochuline PDRN ophthalmic fluid with hyaluronic acid added to the main component PDRN supplies nutrients to ulcerative diseases of the dried cornea and conjunctiva due to lack of nutrition. In addition, contact lenses and frequent use of electronic devices can help alleviate microdamage of damaged conjunctiva.

IOCool has four lineups according to eye symptoms. IoCool water of 0.5% and 1.0% contains carboxymethyl cellulose hydration (CMC), which can help dry the eyes by thickening the tear layer. IOCool Pro contains trehalose hydrate, which can help moisturize the eyes and stabbing eye pain, so you can choose and use it according to your symptoms. Disposable individual packaging allows convenient portable and hygienic use. It is over-the-counter and can be purchased at nearby pharmacies.

An official from Dong-A Pharmaceutical said, "The new product containing PDRN will be a good solution for patients with ulcerative diseases of cornea and conjunctiva due to malnutrition."As eye health requires continuous management in the early stages, I hope you take care of your eye health with IOCool, which has established a customized lineup for each symptom."
