As for why radial keratotomy
isn't practiced anymore, Nejat explained that the procedure has several possible complications.
A 27-gauge hypodermic needle was then used to perform a grid keratotomy
under surgical magnification, taking great care to monitor each needle pass for depth because of the relatively thin appearance of the cornea during slit-lamp examination.
In that study it was postulated that the corneal damage, due to endothelial decompensation many years after RK, was caused by the long term damage arising from the corneal incisions (Sato's anterior-posterior radial keratotomy
) in combination with endothelial losses due to aging .

The accompanying CD-ROM is particularly valuable and includes video of post-LASIK iatrogenic keratectasia, flap complications, bimanual phacoemulsification, phakic IOL, hyperopic shifts after radial keratotomy
and cataract after radial keratotomy
She doesn't remember now which one it was, but the likely technique at that time was one of the first, radial keratotomy
. RK is not used often anymore, but the procedure involves incisions made with a diamond blade in a spoke-like, circular pattern in the cornea.
* After her botched radial keratotomy
Although there is no revenue ruling concerning the deductibility of laser eye surgery, the IRS did issue a letter ruling (9625049) addressing whether radial keratotomy
(RK)--a predecessor of laser eye surgery--was deductible under section 213.
As evidence of what market forces conceivably could do for medical costs, he points to the price of the radial keratotomy
procedure to improve vision.
ISSUE: Who among us has not heard or seen ophthalmologists' advertisements regarding radial keratotomy
? In this interesting Connecticut case, one individual responded to an ophthalmologist who advertised and provided radial keratotomy
