What are the Risks of PRK, LASEK and Epi-LASIK surgery?
The risks of these surgeries fall into two main categories: Vision Loss Risks, and Nuisance Risks. Vision Loss Risks It is very rare to lose vision after laser refractive surgery. When vision is lost in an otherwise uncomplicated procedure, it typically is 1 or less lines on the eye chart of best corrected vision even with extra help from glasses. As such, these surgeries have a very good safety profile. Two other ways may exist in which vision could be lost to a more severe degree. Infection: Since cuts are made on the eye, it is possible that bacteria could gain access to the corneal tissue and start an infection. Scarring from such an infection could lead to vision loss. This is very uncommon as powerful antibiotics are used after surgery to prevent infection. The risk of severe infection is probably less than 1 in 500. Progressive corneal warpage (Ectasia): In this condition, the cornea begins to warp in odd directions, leading to loss of vision. Occasionally, a corneal transplant
