Post-Cataract Surgery: Vision Changes and Glare Issues - Ophthalmology

More Info

---

After undergoing cataract surgery, it is not uncommon for patients to experience various changes in their vision, including glare, halos, and other visual disturbances. These symptoms can be particularly noticeable at night or in low-light conditions, especially when looking at bright lights.
In your case, the appearance of two long white lines or halos around lights after surgery could be attributed to several factors. First, it is important to understand that the healing process following cataract surgery can take time. The eye may still be adjusting to the new intraocular lens (IOL) that was implanted during the procedure. In your case, you mentioned receiving a non-spherical single-focus lens, which can sometimes lead to different visual experiences compared to the natural lens.

The phenomenon you are experiencing could be related to the following:
1. Healing Process: After cataract surgery, the eye undergoes a healing process that can take several weeks to months. During this time, the cornea and other structures in the eye may still be adjusting, which can lead to temporary visual disturbances, including glare and halos.

2. Lens Characteristics: Non-spherical lenses are designed to reduce spherical aberration and improve overall vision quality. However, they may also produce different light dispersion characteristics, which can lead to glare or halos, particularly in low-light conditions. This is often more pronounced in the early postoperative period.

3. Pupil Size: The size of your pupil can also affect how light enters the eye. In dim lighting, the pupil dilates, which can increase the likelihood of light scattering and the perception of halos or glare. This is a common occurrence, especially after cataract surgery.

4. Residual Astigmatism: If there was any pre-existing astigmatism that was not fully corrected during surgery, or if the new lens has introduced some degree of astigmatism, this could also contribute to the visual disturbances you are experiencing.

5. Corneal Edema: Sometimes, a small amount of swelling in the cornea can occur after surgery, which can lead to visual disturbances. This typically resolves on its own as the eye heals.

Given that you are only three days post-surgery, it is likely that your symptoms may improve as your eye continues to heal. However, it is essential to keep your ophthalmologist informed about your symptoms. They may want to perform a follow-up examination to ensure that everything is healing properly and to rule out any complications, such as infection or improper lens positioning.

In summary, while the glare and halos you are experiencing can be concerning, they are often a normal part of the healing process after cataract surgery. Most patients find that these symptoms diminish over time. However, if they persist or worsen, it is crucial to consult your eye care provider for further evaluation and management. They can provide personalized advice and determine if any additional treatment is necessary to improve your visual comfort.
