Issues Related to Post-Cataract Surgery Refraction
Hello, Doctor.
I am currently 20 years old and have undergone scleral buckle surgery and vitrectomy due to retinal detachment in my right eye, which has resulted in cataracts.
I plan to use a monofocal aspheric intraocular lens.
As a college student, I often need to quickly switch between near and far vision to copy notes from the blackboard.
I am not opposed to wearing glasses, but I want to avoid presbyopia.
I would like to ask if, after leaving a prescription of -2.50 diopters for my right eye, I will be able to see clearly at both near and far distances while wearing my myopia glasses.
I want to avoid the hassle of repeatedly taking off and putting on my glasses during class.
If wearing my myopia glasses in my right eye allows for clear vision at both distances, I would like to understand the reason behind it (my left eye has a prescription of -3.00 diopters, and my goal is to have clear vision at both near and far distances with my glasses on, rather than needing to remove them for near vision, which would be inconvenient during class).
Thank you, Doctor!

Hello Mr.
Chuang: Your left eye is fine, so if your right eye retains -2.50 diopters of myopia, you can see clearly at a distance with your glasses on, but near vision is unclear because you have a single-focus aspheric lens, which needs to be removed for clarity.
However, you can still see clearly up close with your left eye, so there is no need to take off your glasses.
Alternatively, you might consider multifocal glasses, which would allow you to see clearly at both distance and near without having to remove your glasses.

More Info
After cataract surgery, particularly in your case where you have undergone additional procedures due to retinal detachment, managing your vision effectively is crucial, especially as a student who frequently switches focus between near and far objects.
From your description, it seems you are considering a monofocal aspheric intraocular lens (IOL) for your right eye, which is a common choice for cataract surgery. Monofocal lenses are designed to provide clear vision at one specific distance, typically either near or far, but not both. Given that you have a left eye with -3.00 diopters of myopia (300 degrees), and you plan to leave your right eye with -2.50 diopters (250 degrees), this setup will indeed create a situation where you may experience some visual challenges.
When you wear glasses for myopia, they correct your distance vision. However, with a monofocal lens in your right eye, you will likely find that while your distance vision is clear with the glasses on, your near vision may not be as sharp. This is because the lens is not designed to accommodate for near vision, which is essential for tasks like reading notes from a blackboard.
In your case, if you wear myopic glasses for your right eye, you will see distant objects clearly, but you may struggle with near vision unless you remove your glasses. This can indeed be inconvenient in a classroom setting where you need to switch focus frequently.
To address your concerns, here are a few options you might consider:
1. Multifocal or Progressive Lenses: These types of lenses allow for multiple focal points, enabling you to see clearly at various distances without needing to switch glasses. This could be particularly beneficial for your situation, as it would allow you to see both the blackboard and your notes without the hassle of removing your glasses.
2. Contact Lenses: If you are open to wearing contact lenses, you might consider monovision correction, where one eye is corrected for distance and the other for near vision. This can help balance your vision and reduce the need for glasses.
3. Discuss with Your Surgeon: It’s essential to have a thorough discussion with your ophthalmologist about your specific needs as a student. They can provide tailored advice based on your eye health, lifestyle, and visual requirements. They may also suggest a different type of IOL that could better suit your needs.
4. Visual Rehabilitation: After surgery, some patients benefit from vision therapy or rehabilitation to help adapt to their new visual circumstances. This could be something to explore if you find adjusting to your new vision challenging.
In summary, while wearing glasses for your right eye will help with distance vision, you may find near vision lacking due to the monofocal nature of the lens. Exploring multifocal glasses or contact lenses, and having a detailed discussion with your eye care provider, will be crucial steps in managing your vision effectively as a student. This way, you can minimize the inconvenience of switching glasses and maintain clarity for both near and far tasks.
