Strabismus Surgery: Costs, Recovery, and Outcomes - Ophthalmology

More Info

---

Strabismus surgery, commonly referred to as eye muscle surgery, is a procedure aimed at correcting misalignment of the eyes, such as in cases of strabismus (crossed eyes or wall eyes). Understanding the costs, recovery, and outcomes of this surgery is crucial for anyone considering it. Here’s a detailed overview addressing your questions:

A.) Cost of Strabismus Surgery
The cost of strabismus surgery can vary significantly depending on various factors such as the geographical location, the surgeon's experience, the facility where the surgery is performed, and whether the procedure is covered by health insurance. In Hong Kong, the cost can range from approximately HKD 20,000 to HKD 50,000 or more. It's advisable to consult with your healthcare provider or the surgical facility for a detailed estimate, including any potential additional costs for pre-operative assessments and post-operative care.


B.) Duration of the Surgery
Strabismus surgery is generally considered a minor surgical procedure. The actual surgery typically lasts between 30 minutes to 1 hour. However, you should also account for pre-operative preparations and post-operative recovery time at the facility, which can extend your total time at the hospital to several hours. While it is not classified as a major surgery, it is still performed under general anesthesia or local anesthesia with sedation, depending on the patient's age and the complexity of the case.


C.) Number of Surgeries Required
In some cases, patients may require more than one surgery to achieve optimal alignment of the eyes. The likelihood of needing multiple surgeries depends on the severity of the strabismus, the specific muscles involved, and how well the eyes respond to the initial surgery. Many patients, however, achieve satisfactory results after just one procedure. Your ophthalmologist will assess your specific situation and provide guidance on the expected outcomes.


D.) Longevity of Results
While strabismus surgery can significantly improve eye alignment, it is important to note that the results may not be permanent for everyone. Some patients may experience a recurrence of strabismus over time, which can happen due to factors such as muscle fatigue, changes in vision, or natural aging processes. The timeline for potential recurrence can vary widely; some may notice changes within months, while others may maintain alignment for years. Regular follow-up appointments with your eye care provider can help monitor any changes.


E.) Double Vision Post-Surgery
If you currently experience double vision (diplopia) due to your strabismus, it is possible that this symptom may persist after surgery, especially if the underlying cause of the double vision is not solely related to the eye alignment. In some cases, surgery can help alleviate double vision, but it is not guaranteed. Your ophthalmologist may recommend additional treatments, such as vision therapy, to help improve binocular vision and reduce double vision.


F.) Vision with Amblyopia (Lazy Eye)
Since you mentioned having amblyopia (lazy eye) in your left eye, it is crucial to understand that surgery alone may not fully restore normal vision in that eye. After surgery, if both eyes are aligned, you may still experience differences in visual acuity due to the amblyopia. The brain may favor the stronger eye, leading to continued visual imbalance. Vision therapy or patching the stronger eye may be recommended to help improve the vision in the amblyopic eye.
In conclusion, strabismus surgery can be an effective way to correct eye alignment and improve visual function. However, it is essential to have realistic expectations and to discuss all concerns with your ophthalmologist, who can provide personalized advice based on your specific condition. Regular follow-ups and adherence to any recommended therapies will be key to achieving the best possible outcomes.
