Femtosecond LASIK found effective for post-RK hyperopia

A femtosecond is a measure of time. Let's put this tiny measurement of time in perspective: the difference between a femtosecond and a second is the difference between a second and about 32 million years.

A femtosecond laser is now being successfully used in LASIK surgery as a means to treat secondary hyperopia resulting from previous RK surgery.

The study, posted in the July issue of Journal of Cataract and Refractive Surgery, claimed that most complications occurred in patients whose eyes already had more than eight existing RK incisions.
