The "Modern People's Corneal Care Laboratory", which raises awareness about the risk of damage to the cornea (black eye area) and how to care for it, is to understand the actual use of eye drops by consumers who tend to overuse their eyes due to corona damage. Under the supervision of Professor Masakazu Yamada of the Faculty of Medicine, "Survey on the actual use of eye drops in Corona" (conducted in March 2021) was conducted.As a result, it became clear that one in four people had exceeded the appropriate number of times.
As a result of the survey, 47.5% of eye drop users answered that the number of eye drops increased due to corona sickness, of which 6% answered that they had 7 or more times, which exceeds the upper limit of 26.0 times of appropriate number of times, which is about 4 people. It became clear that one person was instilling more than the appropriate number of times.Be aware that if you apply too much eye drops, the oil film layer of the tears may be destroyed and the cornea may be damaged, and if it is already damaged, it may worsen the wound.
When asked about their awareness of the number of eye drops, about half of the respondents said, "I don't care about the upper limit of the number of eye drops, but every time I feel a symptom." It became clear that he did not understand the risks of excessive eye drops.
Also, only 7.4% knew that preservative-containing eye drops could affect corneal wounds.The preservative contained in the eye drops is formulated to prevent the growth of various germs on the eye drops after opening, and there is no particular problem as long as the eye drops are instilled at an appropriate dosage.However, if the number of times is exceeded, the cornea may be damaged, and if the cornea is already damaged, the preservative may worsen the damage even with the proper dosage. ..
Only 7.4% and 9.6% of the respondents knew this information, respectively, highlighting the fact that little is known about the risk of preservatives in eye drops.When asked if preservatives were not added to the eye drops actually used, 66.5% answered "I don't know", and there are many people who do not use preservatives as a selection criterion when choosing eye drops. all right.
Professor Yamada commented on the proper use and selection of eye drops. Some people have scratches on their cornea.If you have rough eyes, tingling pain, or more severe symptoms than before, your cornea may be scratched.I would like people who feel symptoms to make good use of eye drops, such as choosing eye drops that do not contain preservatives. I explained.
* A condition in which the cornea is injured is also called corneal epithelial disorder, and is a corneal disease that develops when the cornea is injured due to various causes such as "dry eyes".
