Cataract Surgery: Ultrasound vs. Laser - Risks and Considerations for Seniors

Cataract surgery

Hello Doctor, my grandmother was recently diagnosed with cataracts and has not addressed it for some time.
What are the differences between ultrasound and laser surgery? What are the risks associated with each? Given that my grandmother is 78 years old and has mild heart disease and hypertension, will this have any impact? Thank you.

Thank you very much for your question.
The misunderstanding regarding cataract laser surgery has persisted in Taiwan for nearly a decade, and this concept is deeply ingrained in patients' minds.
Sometimes, doctors are concerned that patients may misunderstand the hospital's lack of high-tech equipment, and they do not clarify this with patients one by one.
Currently, ultrasound is used worldwide to treat cataracts, while lasers are only employed to treat capsular opacification after cataract surgery.
The success rate of cataract surgery is between 90% and 95%, but as the severity of cataracts increases, the likelihood of complications also rises.
The procedure is primarily performed under local anesthesia, allowing patients with mild heart disease and hypertension to undergo surgery.
Additionally, cataracts predominantly affect the elderly, so most surgical patients are older adults.
Our hospital currently utilizes the latest torsional ultrasound phacoemulsification device, which is the only one in the Taoyuan area and also the only one in a public hospital.
It offers high efficiency, low thermal injury, and high safety, with incisions that are 20-30% smaller than those of conventional small incision surgeries, for your reference.

More Info

Cataract surgery is a common procedure, especially among seniors, and understanding the differences between ultrasound and laser techniques is crucial for making an informed decision.
Differences Between Ultrasound and Laser Surgery:
1. Technique:
- Ultrasound (Phacoemulsification): This is the traditional method for cataract surgery. It involves using ultrasonic waves to break up the cloudy lens (cataract) into tiny pieces, which are then suctioned out. This technique has been the gold standard for many years and is widely practiced.

- Laser Surgery: Laser-assisted cataract surgery uses a femtosecond laser to perform certain steps of the procedure, such as creating incisions and breaking up the cataract. While this method can offer precision, it is not universally available and may not be necessary for all patients.

2. Recovery Time: Both methods generally have similar recovery times, but some studies suggest that laser surgery may result in slightly less postoperative inflammation and quicker visual recovery.

3. Cost: Laser surgery is often more expensive than traditional ultrasound surgery, as it involves advanced technology and equipment.

Risks Associated with Each Method:
Both techniques have a high success rate, typically around 90-95%, but they do carry some risks:
- Common Risks: These include infection, bleeding, retinal detachment, and inflammation. The risk of complications can increase with the severity of the cataract and the overall health of the patient.

- Specific Risks: Laser surgery may have unique risks associated with the laser itself, such as corneal burns or incomplete cataract removal if the laser does not function properly.

Considerations for Seniors with Pre-existing Conditions:
Given that your grandmother is 78 years old and has mild heart disease and high blood pressure, these factors should be taken into account:
1. Heart Disease and High Blood Pressure: These conditions can increase the risk of complications during surgery. However, cataract surgery is typically performed under local anesthesia, which minimizes the risks associated with general anesthesia. It is essential for her to be evaluated by her cardiologist before surgery to ensure she is stable enough for the procedure.

2. Age Factor: Older patients may have a higher risk of complications due to other underlying health issues. However, cataracts are common in this age group, and the benefits of surgery often outweigh the risks.

3. Postoperative Care: After surgery, seniors may require assistance during recovery, especially if they have mobility issues or other health concerns. Ensuring a safe environment for recovery is crucial.

Conclusion and Recommendations:
In conclusion, both ultrasound and laser cataract surgery are effective options, and the choice may depend on the specific circumstances of your grandmother's health, the severity of her cataracts, and the availability of technology. It is advisable to consult with an ophthalmologist who can assess her individual case and recommend the best approach. Given her age and health conditions, a thorough preoperative evaluation is essential to minimize risks and ensure a successful outcome.
If you have further questions or concerns, do not hesitate to reach out to her healthcare provider for personalized advice.
