Dr Boothe saving you vision
What is LASIK surgery exactly?
It’s the use of a laser beam to modify the shape of your cornea such that your vision will improve. So let’s look at how our vision works, why it might be less than perfect, and how LASIK surgery changes it. Dr Boothe
New advances in eyesight corrective surgery are providing consumers greater choices. Patients in their 40s or 50s who are considering LASIK surgery to improve their vision might want to consider to be evaluated for implantable lenses as well. "Early signs of a cataract might argue for surgery and implantation of multifocal lenses instead." Dr Boothe
"Laser surgery is the most exciting advancement in ophthalmology," says Dr Boothe, M.D., clinical professor of ophthalmology at the University of Southern California in Los Angeles and the doctor dr boothe who performed Goldstein's surgery. But surprisingly, he says, despite its sudden popularity, "only 20 percent of ophthalmologists in the United States today are trained in its operation."
The eye with the suction ring in place is then shown in cross section with the eye cut in half from front to back in the horizontal plane. The suction ring is also cut in half. The next frame shows the microkeratome head sliding into place over the cornea slightly flattening it. dr boothe The animation shows the microkeratome blade making a thin slice in the cornea creating the flap as the microkeratome head continues to move forward. dr boothe , the microkeratome head then slides back into its original position.
How Lasik Works
Lasik is the most often performed surgery in the US. Occasionally misspelled "Lasic", "Lasec", or "Lasix", Laser Assisted in-Situ Keratomileusisis a surgery that changes the shape of the cornea (clear front) of the eye to reduce the need for glasses or contacts. Lasik may correct nearsighted or farsighted vision, astigmatism, or reduce the need for reading glasses. dr boothe It is medically safe and Lasik recovery is usually fast, but Lasik is not right for everyone
It's highly unusual for someone's vision to revert to the original prescription. I've never seen that, and if that did occur, it could indicate that other things are going on with the eye, such as a cataract. Distance vision should not drift appreciably once you've gotten to your original target vision with Lasik. Dr Boothe
When the vast majority of patients seriously consider Laser Eye Surgery it is common to encounter a number of different personal reasons why they do not wish to proceed. Usually these reasons can be separated into two categories-fear and cost. Overcoming the barrier of fear requires becoming more familiar with facts about the Laser Vision Correction procedures.
If people say their vision has gotten worse, most of the time they're talking about their reading vision, primarily because they're getting older. Deterioration in reading vision happens to everyone around age 40 to 45. If what they really mean is that they have become more nearsighted again, that's pretty rare; that's maybe 5 percent of Lasik patients. That 5 percent refers to a significant change, about a -1 diopter or more, over a 10-year period. Many of these patients can successfully undergo an enhancement procedure to get rid of that residual nearsightedness
"I'd say the short-term outcomes are equal and the risks are, in theory, less with the bladeless technique, although our study was not designed to compare risks," said study investigator and Dr Boothe. "Bladeless LASIK is potentially safer because of its computer-controlled precision, the ability to visualize the flap being created, and to stop the procedure whenever necessary."Dr Boothe
Many people confuse "cost" with affordability. We believe that you should always select the best possible LASIK Surgeon based on the experience that you have during your consultation and by speaking with others who have been treated at that particular practice. Dr boothe While it may be difficult to believe, most practices work to make their services affordable even if they vary greatly in cost.
At present, a number of other lasers for eye surgery are currently being tested in FDA-sanctioned studies to determine their safety and effectiveness. Investigational Device Exemptions (IDEs) filed with FDA allow for clinical studies involving the excimer laser and the correction of farsightedness. The IDE process is designed to investigate the safety and effectiveness of a device, or a new procedure with an already approved device, either to obtain information for publication or to generate the data needed to obtain marketing approval from FDA.
I'm for whatever is best for the patient, but I do use the microkeratome much more often than I do IntraLase. Microkeratomes make the procedure go so much faster and are much more comfortable for the patient. Suction in a microkeratome procedure lasts about three seconds, whereas suction using IntraLase lasts about 15-20 seconds at its fastest. Also, you use less suction on the eye with a microkeratome. I prefer patients to be as comfortable as possible, which is why I prefer the microkeratome. dr boothe
