The cornea is responsible for refracting or bending light toward the center of the retina and refractive errors happen when the shape of the cornea causes the refraction to be off center.
Laser eye surgery after rk.
Laser technology and modern day procedures like lasik have made radial keratotomy obsolete but the procedure did play an important role in the history of refractive surgery according to.
Radial keratotomy rk is an antiquated technique for the most part and it is no longer routinely performed.
There are challenges in both the lens power estimation as well as in the intra operative surgical technique.
Generally speaking are previous rk patients ever eligible and appropriate candidates for a laser corrective procedure lasik.
Prk photorefractive keratectomy is a laser eye surgery that corrects refractive vision errors by changing the shape of the cornea.
Patients should note that the predictability of all types of surgery are less accurate after rk compared with an eye that has not had any previous surgery.
In these patients the cornea may need to be smoothed using topography guided laser eye surgery and vision may be improved by combining with one of the procedures listed above.
There are challenges in both the lens power estimation as well as in the intra operative surgical technique.
It is helpful to divide these decisions into short term and potential long term consequences.
Prior to laser eye surgery another vision correction surgical procedure known as radial keratotomy was widely used.
Vision correction by diamond.
Though it seems like laser eye surgery has been around forever it has in fact only been a common procedure for just over 20 years.
Radial keratotomy rk eye surgery this procedure was once of the most common ways to correct nearsightedness.
Doing cataract surgery in this eye will not be routine.
Because rk was done routinely from the early 1980s to the mid 1990s and weakens the cornea many of these patients come in with farsighted prescriptions and early cataracts because they are age fifty and older making lensectomy iol my procedure of choice for the majority.
As mentioned with prk over previous corneal surgery like rk there is an increase in the incidence of haze.
Doing cataract surgery in this eye will not be routine.
But with the rise of more effective procedures like lasek lasik and prk it s.
Radial keratotomy rk is an antiquated technique for the most part and it is no longer routinely performed.
Further the incidence of haze rises with every prk procedure that is done after rk.
I am 60 years old and had a successful radial keratotomy rk procedure a surgery to correct nearsightedness done in 1996.
