Keratoconus: Safety, Stability, and Treatment Options in Taiwan - Ophthalmology

More Info

---

Keratoconus is a progressive eye condition characterized by the thinning and bulging of the cornea, leading to visual distortion. It typically manifests in adolescence and can significantly impact a person's quality of life. In Taiwan, as in many other countries, treatment options for keratoconus have evolved, and patients often face decisions regarding the best course of action based on their specific condition and lifestyle.


Safety and Stability of Corneal Ring Implantation
Corneal ring implantation, or intracorneal ring segments (ICRS), is a surgical procedure designed to flatten the cornea and improve visual acuity in patients with keratoconus. The safety of this procedure has been well-documented in various studies. Generally, the implantation of corneal rings is considered safe, with a low incidence of complications. Common side effects may include temporary discomfort, glare, or halos around lights, but serious complications are rare.

In terms of stability, studies have shown that corneal ring segments can provide significant improvement in visual acuity and corneal shape. The effects are often stable over time, but individual results can vary. Regular follow-up with an ophthalmologist is crucial to monitor the condition and assess the effectiveness of the treatment.

Improvement in Vision
The improvement in vision after corneal ring implantation can be substantial. Many patients experience a reduction in their dependence on glasses or contact lenses. However, the degree of improvement can depend on the severity of the keratoconus and the specific characteristics of the patient's cornea. In your daughter's case, with a significant degree of myopia and astigmatism, the expected improvement may be notable, but it is essential to have realistic expectations and discuss them with the treating physician.


Cost and Insurance Coverage
In Taiwan, the cost of corneal ring implantation can be a concern, especially since it is often not covered by the National Health Insurance (NHI). The price can vary depending on the medical center and the specific type of ring used, but patients should be prepared for a significant out-of-pocket expense. It is advisable to consult with the medical center for a detailed breakdown of costs, including any pre-operative assessments and post-operative care.


Waiting Time for Corneal Transplantation
If corneal ring implantation is not effective or if the keratoconus progresses, a corneal transplant may be necessary. The waiting time for a corneal transplant in Taiwan can vary widely based on factors such as donor availability and the urgency of the case. It is not uncommon for patients to wait several months to over a year for a suitable donor cornea. The costs associated with corneal transplantation can also be substantial, including pre-operative evaluations, the surgery itself, and post-operative care.


Conclusion
In summary, corneal ring implantation is a viable option for managing keratoconus in Taiwan, with a good safety profile and potential for significant visual improvement. However, it is essential to weigh the costs and consider the long-term management of keratoconus, including the possibility of future treatments such as corneal transplantation. Regular follow-ups with an ophthalmologist are crucial to monitor the condition and make informed decisions about treatment options. It is recommended to have an open discussion with the healthcare provider to understand the best course of action tailored to your daughter's specific needs.
