Corneal Injuries: Causes of Blurred Vision and Astigmatism - Ophthalmology

More Info

Corneal injuries can significantly impact vision, leading to symptoms such as blurred vision and astigmatism. When the cornea, which is the clear front surface of the eye, is injured—especially by a puncture or abrasion—it can result in various complications that affect visual clarity.

In your case, the initial injury to the cornea may have caused a disruption in its normal structure. The cornea is composed of several layers, and any damage can lead to scarring or irregularities in its shape. Even if the cornea has healed, it may not return to its original state, which can result in visual disturbances. The healing process can sometimes lead to the formation of scar tissue, which can scatter light entering the eye and cause blurred vision. This is particularly true if the scar is located in the central visual axis of the cornea.

Regarding your increase in astigmatism from 125 degrees to 200 degrees, this change is indeed related to your corneal injury. Astigmatism occurs when the cornea is not perfectly spherical; instead, it has an irregular shape. This irregularity can be a direct result of the injury and subsequent healing process. When the cornea heals, it may not heal uniformly, leading to areas that are steeper or flatter than normal, thus increasing astigmatism. The higher the degree of astigmatism, the more significant the impact on your vision, leading to further blurriness.

The blurred vision you are experiencing can be attributed to a combination of factors: the healing of the cornea, the potential for scarring, and the increase in astigmatism. It is essential to have regular follow-ups with your eye care professional to monitor the healing process and assess any changes in your vision.

In terms of treatment options, if your vision remains blurred despite the cornea healing, your eye doctor may recommend corrective lenses, such as glasses or contact lenses, specifically designed to address your astigmatism. In some cases, if the corneal irregularity is significant and affecting your quality of life, surgical options such as corneal refractive surgery (e.g., LASIK or PRK) may be considered, but this would depend on the overall health of your eye and the specifics of your corneal condition.

Additionally, it is crucial to protect your eyes from further injury and to follow any prescribed treatment regimen, which may include lubricating eye drops to alleviate dryness and discomfort. If you notice any sudden changes in your vision or experience pain, it is vital to seek immediate medical attention.

In summary, your blurred vision and increased astigmatism are likely consequences of the corneal injury you sustained. Regular monitoring and appropriate corrective measures can help manage these symptoms and improve your visual acuity. Always consult with your eye care professional for personalized advice and treatment options tailored to your specific situation.
