Is glaucoma associated with severe myopia a reason to withhold lasik surgery? I am considering a lasik surgery to improve my poor vision due to advanced myopia (40 years old). I am also suffering from glaucoma and I use specific eye drops for it. How will

Many : Many patients with glaucoma have undergone lasik surgery with great results. The only concern is that lasik involves use of a stabilizing instrument that temporarily increases eye pressure while creating the lasik flap. If glaucoma is very advanced, it is possible that further vision damage could occur. There are other options that don't involve increasing the pressure, including epilasik, prk, or asa. Another possibility is the use of lens implants, with the implantable contact lens (icl) surgery. Check out this page on my website:. ...Read more

Refraction will tell: Both astigmatism and myopia (nearsightedness) can blur your distance vision. If you have a large amount of astigmatism you may notice a starburst pattern from red tail lights at night. High amounts of astigmatism will blur both near and far vision, while myopia will blur the distance , with near vision being clear. Get a refraction to find out for sure. ...Read more
