Post-Cataract Surgery Eye Drops: When to Continue and Possible Vision Issues - Ophthalmology

More Info

---

After cataract surgery, it's common for patients to have questions regarding the use of eye drops and any changes in vision. In your mother's case, she underwent cataract surgery on September 22 and was prescribed two types of eye drops: "復眼康" (likely a lubricating or anti-inflammatory drop) and "可樂必妥" (which is typically a steroid drop). These medications are crucial for promoting healing and preventing inflammation after surgery.


When to Continue Eye Drops
Generally, the use of these eye drops should continue as prescribed by the surgeon. If the surgeon instructed to use them until a specific date (in this case, until the stitches were removed on September 29), it is essential to follow that guidance unless otherwise directed. Since your mother continued to use the drops until October 8, it’s important to consider the following:
1. Consult the Surgeon: Since the next appointment is not until November 12, it would be advisable to contact the surgeon's office for guidance on whether to continue using the drops. They may recommend continuing the drops for a certain period post-surgery, especially if there are signs of inflammation or discomfort.

2. Signs of Complications: If your mother is experiencing sudden changes in vision, such as blurriness, along with symptoms like stinging or itching, it could indicate a few potential issues:
- Intraocular Inflammation: This can occur after surgery and may require continued use of anti-inflammatory drops.

- Infection: Though less common, an infection can cause similar symptoms and requires immediate attention.

- Corneal Edema: Sometimes, the cornea can become swollen post-surgery, leading to blurred vision.

- Changes in Vision: It’s also possible that the vision may fluctuate as the eye heals, especially in the first few weeks after surgery.


Possible Vision Issues
The sudden blurriness in vision can be attributed to several factors:
- Healing Process: After cataract surgery, the eye undergoes a healing process. It is not unusual for vision to fluctuate during this time, especially in the first few weeks.

- Residual Refractive Error: Sometimes, the lens implant may not fully correct the vision, leading to residual nearsightedness or farsightedness.

- Dry Eye: Post-surgery, patients often experience dry eyes, which can cause discomfort and blurred vision. Using lubricating drops can help alleviate these symptoms.

- Cataract Formation: In some cases, a secondary cataract (posterior capsule opacification) can develop, leading to blurred vision. This condition can be treated with a simple outpatient procedure.


Recommendations
1. Contact the Surgeon: Given the symptoms your mother is experiencing, it is crucial to reach out to the surgeon's office for advice. They may want to see her sooner than the scheduled appointment if there are concerns about infection or other complications.

2. Continue Eye Drops: Unless advised otherwise, it is generally recommended to continue using the prescribed eye drops as they help in the healing process and reduce inflammation.

3. Monitor Symptoms: Keep an eye on any changes in symptoms. If the blurriness worsens or if new symptoms arise, seek medical attention promptly.

4. Avoid Self-Medication: It’s important not to stop or change the medication regimen without consulting a healthcare professional, as this could lead to complications.

In conclusion, while it is common to experience some changes in vision after cataract surgery, sudden blurriness and discomfort should not be ignored. Prompt communication with the surgeon will ensure that your mother receives the appropriate care and guidance for her recovery.
