Home > Health & Wellness > Health Library > Nearsightedness: Hyperopic Shift After Surgery
Most people who have radial keratotomy (RK) surgery
gradually become more farsighted for at least 8 to 10 years after surgery. This
is called the hyperopic shift. It is not clear what causes
the shift. It's also not clear how long it may last or how bad it will get.
The effects depend on the person's age and whether
the person is nearsighted or farsighted after the surgery.
