Post-cataract surgery

I recently had surgery on my right eye, and the doctor said my vision is 1.0.
I received an Alcon non-diffractive presbyopia-correcting intraocular lens, but three weeks later, I still cannot see clearly at intermediate distances.
My first question is whether my vision is actually not 1.0 and if I have developed hyperopia, which is causing the difficulty at intermediate distances.

My second question is regarding my left eye; the doctor mentioned that if I undergo surgery, I can leave it at -1.00 diopters for near vision.
Would this result in any disparity or discomfort?
My third question is whether my myopia and presbyopia will change over the years after the surgery.

Lastly, I am experiencing halos around lights, and when light comes from the side or above, I see shadows that affect my vision.
Is this normal?
Thank you for your patient response, and I wish you all the best.

Hello: 1.
Regarding your difficulty seeing at intermediate distances after surgery on your right eye, there are several possibilities.
First, it may take some time to adapt to the new intraocular lens.
Additionally, you may need to wear appropriate glasses post-surgery to ensure clear vision at all distances.
2.
If the left eye underwent surgery and is left with +1.00 diopters for near vision, this is typically done to correct presbyopia.
Disparity is usually not a major issue, as both eyes typically work together to provide clear vision.
3.
Over time, your prescription may change; while the power of the intraocular lens does not change, alterations in the cornea or even the eyeball can affect your vision prescription.
4.
Halos and glare are common phenomena after surgery, but these symptoms should gradually improve during the recovery process.
However, if these issues persist or worsen, you should consult your ophthalmologist as soon as possible to receive accurate guidance.

More Info

Post-cataract surgery, many patients experience a variety of visual issues and concerns, which can be quite distressing. Based on your questions, let's address each one in detail.

1. Vision Clarity and Possible Hyperopia:
You mentioned that your doctor indicated your vision is 1.0, yet you are having difficulty seeing clearly at intermediate distances. It is possible that your vision may have shifted towards hyperopia (farsightedness) post-surgery, especially if the intraocular lens (IOL) used was not perfectly aligned with your visual needs. The Alcon non-diffractive multifocal lens you received is designed to provide a range of vision, but individual results can vary. If you are experiencing blurred vision at intermediate distances, it may be worthwhile to have your refraction checked again to determine your current prescription accurately. Sometimes, the brain needs time to adapt to the new lens, but if the issue persists, further evaluation is necessary.

2. Potential for Visual Discrepancy with Left Eye Surgery:
Regarding your left eye, if your doctor suggests leaving 100 degrees of myopia to facilitate near vision, this can indeed create a visual disparity between your two eyes. This condition, known as anisometropia, can lead to discomfort, difficulty in focusing, and even double vision in some cases. However, many patients adapt well to such differences over time. It is essential to discuss this with your ophthalmologist, who can provide personalized advice based on your specific visual needs and lifestyle.

3. Changes in Refractive Error Over Time:
After cataract surgery, it is common for patients to wonder about the stability of their vision. While many patients enjoy stable vision post-surgery, it is possible for refractive errors, such as myopia or presbyopia (age-related difficulty in seeing close objects), to change over time. Factors such as age, overall eye health, and the natural aging process of the eye can influence these changes. Regular follow-ups with your eye care provider are crucial to monitor any changes and to address them promptly.

4. Light Halos and Shadows:
Experiencing halos around lights and shadows when light comes from certain angles is not uncommon after cataract surgery, especially with certain types of IOLs. This phenomenon can be attributed to the way light interacts with the lens and the healing process of the eye. While some patients find these symptoms diminish over time as the eye heals and adapts, others may continue to experience them. If these visual disturbances are bothersome or significantly impact your quality of life, it is essential to discuss this with your ophthalmologist. They may suggest options to help alleviate these symptoms or provide reassurance that they may resolve with time.

In summary, it is crucial to maintain open communication with your eye care provider regarding your concerns. They can offer tailored advice and potential solutions based on your specific situation. Regular follow-ups are essential to ensure your eyes are healing properly and to address any ongoing issues. Remember, your comfort and visual clarity are paramount, and your doctor is there to help you navigate these challenges.
