How can refractive surgery be a potential public health problem if patients are happy with the results?
Health government agency's are doing nothing to change refractive surgery sad situation, maybe it's time to contact the Road Safety Agency's. If this agency's do nothing after warned about the problems, they may be responsible for many deaths in the road.
The article is from 1994. The same is happening today with lasik, lasek, prk, icl, relex smile.. The new FDA LASIK Quality of Life Collaboration Project show enormous incidence of halos, glare, starburst.... It's is a major public health problem!

"A keratorefractive (Radial Keratotomy, RK) patient may simultaneously be happy with the result of surgey and have degraded vision - How can refractive surgey be a potential public health problem if patients are happy with the results? Inherent in this question is the assumption that a patient without complaint is a patient without optical degradation. That argument does not hold up to closer scrutiny. The keratoreractive literature contains disturbing examples of patients who have visual handicaps that place themselves and others at significant risk for nighttime driving accidents and yet that are happy with the results.
A recent study of patient satisfaction after radial keratotmy consisted of 100 former contact lens patients who underwent radial keratotomy. Comlaints after radial keratomy were rarely mentioned spontaneously, but when elicited, the study found a high complaint rate. Of the patients 10% complained of glare, 7% of "suboptimal visual acuity," 5% of astigmatic blur and headache, 3% near-vision problems and 2% photophobia. Fifty percent complained of "impaired night vision." Half of that group needed spectaces for night driving. Six percent decided against operation in the fellow eye. Despite these findings, 93% of the patients perferred radial keratotomy to contact lenses."
"We are led to the conclusion that patients will tolerate degraded optical quality (including functionally significant aberrations in night vision) for improved uncorrected vision. They are happy now but how safe are they on our highways at night? How safe will they be when cataract-induced aberration compounds the glare and aberration effects of the cornea; and when early macular disease begins to reduce compensatory mechanisms in the retina?
We need answers to these questions because in 30 years one in four drivers on the road will be older than 65 years."

FDA LASIK Quality of Life Collaboration Project
"Based on our initial analyses of our studies:
Up to 45 percent of participants, who had no visual symptoms before surgery, reported at least one visual symptom at three months after surgery.
Participants who developed new visual symptoms after surgery, most often developed halos. Up to 35 percent of participants with no halos before LASIK had halos three months following surgery.
Up to 30 percent of participants with no symptoms of dry eyes before LASIK, reported dry eye symptoms at three months after their surgery. This is consistent with previous studies.)"

FDA releases LASIK patient survey, warns of large numbers of dissatisfied patients
" These include haloes at up to 35 per cent, followed by starbursts at up to 28 per cent, glare up to 16 per cent, and ghosting up to 6 per cent.""
Refractive Surgery - Very disturbing information
