"Why don't they come up with some better technology to solve the problem..."
Technology CREATED the problem. Every complication of refractive surgery - from RK through PRK to LASIK - was predictable BEFORE the technologies ever took root. The technology was not developed as a gift to mankind; it was created for profit. It's elective. It's plastic surgery that steals tissue from an otherwise perfectly healthy cornea to fix a refractive error (mainly nearsightedness and farsightedness) that is due to a NATURALLY OCCURRING incorrect axial length of the eye.
You state "they have this wonderful thing like LASIK..." - Mo, if LASIK was wonderful, VSRN would not need to exist. It's not all wonderful. It's like saying,"Pie is wonderful. Why don't they solve the problem of it being fattening?" It's the nature of pie to be fattening. We ALL understand that too much pie will drive us to Jenny Craig's website. The nice thing over there is, no one asks why the ravages of pie are not easily fixed.
