Respected user, hi I evaluated your query thoroughly.
* Eye color variation can be explained by 
Polymorphism around the OCA2 gene
* Eye color comes close to being a monogenic Mendelian trait when it comes 
   to inheritance .Expression of blue eyes is recessive, you need 2 copies.
* This in explanation of in born blue eyes & now about your query 
@ 
Laser procedure can turn brown eyes blue
    - Laser works by eliminating the brown 
melanin that`s present in the 
      anterior layers of the 
iris .
    - Fundamental principle is that under every brown eye is a blue eye ,
      Dr.Gregg Homer told CNN adding that there is no actual blue 
      pigmentation in the eye .
      But still long term medical data are awaited with details of procedure
      safety & outcomes , many critics say it is reckless .
@ I would personally suggest to use a tinted 
contact lens of your desired
    color rather than ending up in all these jugglery .
Hope this clears your doubts.
