At age 30, my wife had successful LASIK surgery in 1999 to correct an Rx of (R) -3.75 -1.25 x180 and (L) -3.25 -1.75 x180. She had not worn glasses or contacts since until last October, when it became apparent that she was having a lot of difficulty driving at night.
At age 37, she finally agreed to get an eye exam in October 2006. The results confirmed that her astigmatism had returned with a slight bit of myopia. Her Rx from that exam is (R) -.25 -.75x180 and (L) -.25 -.50 x120. At the time, she agreed to wear her glasses for driving at night, but steadfastly refused to consider them for anything else. After all, she had the LASIK done because she wanted to be glasses-free.
For the first few months, she kept to this usage level. Then over the last 6 months, she is now wearing them for the blackboard at school, anytime she uses the computer or when she is reading. (She doesn't hold the book at arm's lenght though) She also wears perscription sunglasses for driving during the day. It also appears that her eyes have changed further since the exam she had in October 2006.
My questions are:
(1) Is she a candidate for LASIK in the future?
(2) Is she developing presbyopia earlier than usual. or is it the astigmatism that is cauing her issues on the PC and for reading?
(3) Is the increased usage a sign that she is becoming more depdendent on correction (given her strong reluctance to wear glasses)?
