Complications of Untreated Cataracts: What You Need to Know - Ophthalmology

More Info

Dear Ms. Zheng,
Thank you for reaching out with your concerns regarding your father's cataract condition. I understand how distressing it can be to witness a loved one's vision deteriorate, and I appreciate your desire for clarity on this matter. Let’s address your questions regarding untreated cataracts, the implications of surgery, and what to expect.

Complications of Untreated Cataracts:
Cataracts occur when the lens of the eye becomes cloudy, leading to blurred vision. If left untreated, cataracts can lead to several complications:
1. Progressive Vision Loss: As cataracts worsen, they can lead to significant vision impairment, making it difficult to perform daily activities such as reading, driving, or recognizing faces. In severe cases, individuals may only perceive light, as you mentioned about your father.

2. Increased Risk of Falls and Injuries: Poor vision can increase the risk of falls, which can lead to serious injuries, particularly in older adults.

3. Development of Other Eye Conditions: Untreated cataracts can sometimes lead to secondary complications, such as glaucoma, which is an increase in intraocular pressure that can damage the optic nerve.

4. Impact on Quality of Life: The inability to see clearly can lead to frustration, depression, and social withdrawal, significantly affecting a person's quality of life.

Surgical Considerations:
Regarding your father's situation, cataract surgery is generally safe and effective. Here are some points to consider:
- Timing of Surgery: If your father's vision is deteriorating to the point where he can only perceive light, it may be beneficial to consult with an ophthalmologist about the possibility of surgery sooner rather than later. Waiting too long can lead to complications that may make surgery more difficult.

- Health Insurance Coverage: In many regions, including Taiwan, health insurance may cover cataract surgery once the patient reaches a certain age or if the cataracts significantly impair vision. It’s advisable to check with the healthcare provider about the specifics of coverage and whether an early application is possible.

- Surgery Day Process: On the day of surgery, the ophthalmologist will conduct a thorough examination to ensure that your father is a suitable candidate for the procedure. Typically, surgery can be performed on the same day as the consultation, but this depends on the specific circumstances and the surgeon's assessment.

- Post-Surgery Considerations: After cataract surgery, patients may experience some discomfort, but serious complications are rare. Common side effects include mild irritation, light sensitivity, and blurred vision, which usually resolve within a few days. Regular follow-up appointments will be necessary to monitor healing and ensure the best outcome.

Financial Preparation:
The cost of cataract surgery can vary based on the facility, the surgeon's fees, and whether additional procedures (like lens replacement) are needed. It’s best to contact the hospital where your father intends to have the surgery for an estimate. Additionally, you may want to prepare any necessary documents, such as health insurance information and identification.

Conclusion:
In summary, untreated cataracts can lead to significant complications, and timely surgical intervention can greatly improve your father's quality of life. I recommend scheduling a consultation with an ophthalmologist as soon as possible to discuss your father's current condition and the best course of action.
If you have any further questions or need assistance with the next steps, please feel free to reach out.

Wishing your father the best of health and a successful outcome.

Sincerely,
Dr. Cai
