Does Using Dilating Eye Drops Increase Cataract Risk?

Does the use of mydriatic agents cause cataracts?

Recently, I read an article on the forum mentioning that someone had good results controlling myopia with Atropine, but my doctor had previously prescribed me Neostigmine Methylsulfate.
So, I went to the pharmacy to buy Atropine and found out after asking several places that it is sold illegally and requires a prescription.
After trying it once, I felt pain whenever I was exposed to bright light, and wearing a hat and lighter sunglasses didn’t help.
Therefore, I inquired at the optical shop where I got my glasses as a child, and the owner told me that using dilating drops could lead to cataracts and advised me against it.
Is this true? Source of the article: http://www.appledaily.com.tw/appledaily/article/headline/20140830/36055060/(from a reader in Taoyuan County)

Hello, the use of atropine eye drops for myopia must be prescribed by a physician.
Currently, I have not seen any definitive evidence linking atropine eye drops to the development of cataracts.

The concern regarding the use of dilating eye drops and their potential link to cataract development is a common one, especially among individuals who are already managing eye conditions such as myopia. To address your question directly: using dilating eye drops, such as those containing tropicamide or phenylephrine, does not inherently increase the risk of developing cataracts.
Cataracts are primarily age-related and are influenced by various factors, including genetics, prolonged exposure to UV light, smoking, diabetes, and certain medications, particularly corticosteroids. While some studies have suggested that chronic use of certain medications may contribute to cataract formation, the occasional use of dilating drops for eye examinations or treatments does not pose a significant risk.

When dilating drops are administered, they temporarily paralyze the ciliary muscle, allowing the eye care professional to get a better view of the retina and other internal structures. This process can lead to increased sensitivity to light, which you have experienced. Wearing sunglasses and hats can help mitigate this discomfort, but it is not indicative of cataract development.

It's important to note that the claims made by some individuals, such as the one you encountered at the optical shop, may stem from a misunderstanding of the effects of these medications. While it is true that prolonged exposure to certain conditions can lead to cataracts, the occasional use of dilating drops in a controlled clinical setting is not associated with a significant increase in cataract risk.

If you are concerned about the use of specific medications like artopine for myopia control, it is crucial to consult with an eye care professional who can provide guidance based on your individual eye health needs. They can help you understand the benefits and risks associated with different treatments and ensure that you are using the most appropriate options for your condition.

In summary, while it is essential to be cautious about any medication you use, the occasional application of dilating eye drops does not significantly increase the risk of cataracts. Regular eye examinations and discussions with your eye care provider can help you maintain optimal eye health and address any concerns you may have about your vision and the treatments you are receiving.
