Myopia, Astigmatism, and Strabismus: Your Questions Answered - Ophthalmology

More Info

---

Understanding myopia (nearsightedness), astigmatism, and strabismus (crossed eyes) is essential for anyone experiencing vision problems. Let's break down your questions and concerns regarding these conditions, particularly focusing on the possibility of reducing their severity and the implications of treatment options.


Myopia and Astigmatism
Myopia occurs when the eyeball is too long or the cornea has too much curvature, causing distant objects to appear blurry. Astigmatism is caused by an irregular shape of the cornea or lens, leading to distorted or blurred vision at all distances. Both conditions can often be corrected with glasses or contact lenses, but many people wonder if it's possible to reduce their severity over time.

1. Can myopia decrease?
- The statement "it is difficult to decrease by 100 degrees" suggests that while it may be challenging to reduce myopia significantly, it is not entirely impossible. Some individuals may experience a natural decrease in myopia as they age, particularly during their late teens or early twenties. However, this is not guaranteed, and many people may find their myopia stabilizes rather than decreases.
2. Can astigmatism be reduced?
- Similar to myopia, astigmatism can sometimes be improved with corrective lenses, but it is less common for it to decrease naturally. Some treatments, such as orthokeratology (special contact lenses worn overnight to reshape the cornea), may help reduce astigmatism temporarily.


Treatment Options
If you are hesitant about laser surgery (like LASIK), there are alternative methods to manage myopia and astigmatism:
- Glasses and Contact Lenses: These are the most common and non-invasive methods to correct vision. They can help you see clearly without altering the eye's structure.

- Orthokeratology: As mentioned, this involves wearing specially designed contact lenses overnight to reshape the cornea temporarily.

- Vision Therapy: This is a type of physical therapy for the eyes and brain, which can help with certain conditions, including strabismus.


Strabismus and Contact Lenses
Strabismus, or misalignment of the eyes, can sometimes be treated with glasses or contact lenses, but it often requires more specialized treatment.
1. Can people with strabismus wear contact lenses?
- Yes, individuals with strabismus can wear contact lenses. In fact, some may find that contact lenses provide better peripheral vision and comfort compared to glasses. However, the effectiveness of contact lenses in managing strabismus depends on the specific type and severity of the condition. In some cases, surgery may be necessary to align the eyes properly.


Conclusion
In summary, while it may be challenging to reduce myopia and astigmatism significantly, there are various management options available. If you are not interested in laser surgery, corrective lenses remain a reliable choice. For strabismus, contact lenses can be an option, but consulting with an eye care professional is essential to determine the best course of action tailored to your specific needs. Regular eye examinations and discussions with your eye doctor can help you understand your options and make informed decisions about your vision care.
