Right eye
Hello Doctor: Three weeks ago, I underwent cataract surgery on my right eye.
At night, when I see streetlights or car headlights, I notice elongated light beams that are symmetrically spaced on the left and right, extending about several meters to over ten meters in length.
I even see V-shaped light beams when looking at indoor lights in my home.
Have you encountered similar cases? What could be the reason for this? Will this phenomenon diminish or increase over time? Thank you for your response.

It is common to experience light sensitivity, such as photophobia and glare, after cataract surgery.
This occurs because the cloudy lens prior to surgery blocked much of the light, and after the procedure, these symptoms may arise.
Wearing sunglasses can help alleviate these symptoms temporarily, and they will gradually diminish over time.

More Info
After cataract surgery, it is not uncommon for patients to experience various visual disturbances, including the phenomenon you described, where lights appear to have elongated streaks or V-shaped patterns. This condition can be attributed to several factors related to the surgical procedure and the healing process of the eye.
Firstly, the visual disturbances you are experiencing, such as the streaks of light when viewing street lamps or indoor lighting, may be due to a combination of factors including the healing of the cornea, the adjustment of the new intraocular lens (IOL), and the way light is refracted through the lens. After cataract surgery, the eye undergoes a period of healing, during which the cornea may still be slightly swollen or irregularly shaped, leading to visual distortions. This is often referred to as "post-operative glare" or "halos," and it can be more pronounced at night or in low-light conditions.
Additionally, the type of intraocular lens implanted can also play a role in these visual phenomena. Some lenses, particularly multifocal or toric lenses, can create visual disturbances as the brain adjusts to the new way of processing visual information. If you received a standard monofocal lens, the issue could still arise due to the healing process and the eye's adaptation to the new lens.
Regarding whether these symptoms will improve over time, many patients find that visual disturbances diminish as the eye heals, which can take several weeks to months. The brain also adapts to the new visual input, which can further reduce the perception of halos and streaks. However, if the symptoms persist or worsen, it is essential to follow up with your ophthalmologist. They may perform a thorough examination to rule out any complications such as posterior capsule opacification (PCO), which can occur after cataract surgery and may require a simple outpatient procedure called YAG laser capsulotomy to resolve.
In summary, the visual disturbances you are experiencing after cataract surgery are likely related to the healing process and the adaptation to the new intraocular lens. While many patients report improvement over time, it is crucial to maintain regular follow-up appointments with your eye care provider to monitor your progress and address any ongoing concerns. If you notice any significant changes in your vision or if the disturbances become bothersome, do not hesitate to reach out to your ophthalmologist for further evaluation and guidance.
