Dear Cate Keane,
 
Thank you for your email. I am sorry to inform you that we do not have an affiliated clinic in Hanoi to do the pre-operative eye examination for you. The complete eye exam is required at TRSC to see if you are a suitable candidate for LASIK or not.
 
LASIK is able to correct nearsightedness combined with astigmatism up to -10.00 and farsightedness combined with astigmatism up to +4.00. However, the prescription alone does not determine whether you are a LASIK candidate.  Other factors such as corneal thickness, corneal curvature, eye pressure, and the health of your eyes all play a role in determining candidacy. 
 
Other information has been emailed directly to you.

Warm regards,
TRSC International LASIK Center
