Overcorrection makes an eye that was
nearsighted before surgery
farsighted (hyperopia) after surgery. Overcorrection
speeds up the start of
presbyopia. Most people who have overcorrection will
need reading glasses around age 40. Improvements in
surgical techniques are reducing the risk of overcorrection.
Surgery to correct overcorrection is possible. But it is hard to predict
how well it will work.
With radial keratotomy (RK) surgery, the
number of people who are overcorrected or farsighted seems to increase as more
time (years) passes after the procedure. These changes over time are believed
to be caused by the
hyperopic shift . The hyperopic shift is less common in
people who have had laser surgery.
