Pure astigmatism correction with PRK. Is it normal to have ghosting vision in 1 eye when the other is clear 1 month post prk ?

Ghosting one month after PRK can be
caused by many things. Most
commonly would be residual refractive error, ie some remaining astigmatism. This can be easily measured by your
doctor. If this is the case,
typically surgeons wait 3-6 months to retreat with more PRK.

Other possible causes include
dryness, inflammation, swelling in the cornea, or micro-irregular curvatures in
the cornea. Again, your doctor
should be able to determine precisely what is causing the ghosting and help you
address it.

When high levels of pure astigmatism are treated ghosting or glare can occur especially when custom technology is not used due to the generation of aberration from the laser treatment. For most patients this will clear over time. If this does not clear a refinement procedure can be performed making use of custom wavefront technology to reduce or eliminate your symptoms.
