There can be many common causes of blurry vision 1 month after laser vision correction (ReLExSMILE, LASIK, PRK) such as dry eye, post-op inflammation or residual refractive power.
We often see dry eye causing transient blurry vision for patients who have undergone laser vision correction. As your vision improves after surgery, it is normal for patient to increase their work load as well. When one uses their eyes for long hours of near work, they do not blink as much and this can increase dry eye symptoms leading to blurry vision.
Another possible cause of blurry vision can be due to post-op inflammation leading to fluctuation of vision. It is important to note that your eyes are still healing and recovering; it usually takes 3 months for your vision to fully stabilise after surgery.
If there is residual refractive power due to under- or over-correction, it is best to discuss with your eye surgeon the next course of action. I would suggest visiting your ophthalmologist to ascertain the reason for the blurry vision and have it treated accordingly.
