Confusion regarding the prescription of Corning Optical's lenses during an ophthalmic examination?


Hello, Doctor He.
I am currently 20 years old and went for my final eye examination before studying abroad.
During this examination, a microsonography was performed (I used the English term as I am unsure of the correct Chinese name).
The doctor mentioned that the results were relatively normal for the macula and optic nerve, but due to persistently elevated intraocular pressure (which has been high due to my thicker cornea), the doctor indicated that I would need to schedule a visual field test to confirm whether I have glaucoma.

When I was picking up my medication, I noticed one of the prescriptions was for Koryn Yuni, which is indicated for early senile cataracts.
However, the doctor did not mention anything about cataracts during the consultation.
I would like to ask you, Doctor He, is Koryn Yuni prescribed only if cataracts are confirmed, or can it also be prescribed for suspected symptoms or as a preventive measure? Additionally, could its components be applicable for treating other conditions? I did not have the opportunity to ask during the busy clinic visit.

This medication should only be prescribed if cataracts are present; however, even if cataracts are not present, using it should not pose any issues.

Hello! Thank you for your question regarding the prescription of Corning Unis and its relevance to your eye health concerns. It’s great that you are being proactive about your eye health, especially as you prepare for studying abroad.
Corning Unis, or more commonly known as Corning® Vision™ lenses, are designed to enhance visual performance and comfort, particularly for individuals who may experience visual disturbances due to various eye conditions. While you mentioned that the clinical use of this product is primarily for early-stage cataracts, it’s important to understand that eye care professionals often prescribe treatments based on a comprehensive assessment of a patient’s overall eye health, not just the presence of a specific condition.

In your case, the fact that your eye pressure is consistently high and that you have a thicker cornea could indicate a risk for developing glaucoma, a condition that can lead to vision loss if not managed properly. The decision to prescribe Corning Unis may not necessarily mean that you have cataracts; rather, it could be a preventative measure or a way to enhance your visual clarity while your eye health is being monitored.
The components of Corning Unis lenses are designed to filter out harmful blue light and reduce glare, which can be particularly beneficial for individuals who spend a lot of time in front of screens or in bright environments. This is especially relevant for students and professionals who may experience eye strain or discomfort due to prolonged visual tasks.
Regarding your concern about whether the prescription indicates a confirmed diagnosis of cataracts, it’s essential to clarify that many eye care professionals may prescribe treatments that can help manage symptoms or improve visual function even if a condition is not fully developed. For instance, if there are early signs of cataracts or if your visual acuity is affected by other factors, such as high eye pressure or potential glaucoma, your doctor may choose to prescribe lenses that can help mitigate these issues.

As for your upcoming visual field test, this is a crucial step in assessing your risk for glaucoma. Elevated intraocular pressure (IOP) is a significant risk factor for glaucoma, but it is not the only one. The visual field test will help determine if there are any areas of vision loss that could indicate damage to the optic nerve, which is often associated with glaucoma.

In summary, the prescription of Corning Unis lenses does not definitively indicate that you have cataracts; it may be a proactive approach to enhance your visual comfort and performance while your eye health is being monitored. It is always advisable to follow up with your eye care provider for clarification on any prescriptions and to discuss your specific concerns regarding your eye health. They can provide personalized insights based on your unique situation and help you understand the rationale behind their recommendations.

If you have further questions or concerns, don’t hesitate to reach out to your eye care professional. They are there to help you navigate your eye health as you prepare for your exciting journey abroad!
