LASIK SURGERY
Laser-Assisted in Situ Keratomileusis
LASIK or Lasik (Laser-Assisted in Situ Keratomileusis), commonly referred to as laser eye surgery, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses. Major side effects include halos, starbursts, night-driving problems, keratoconus (corneal ectasia), and eye dryness.
Officially started in:
On 20 June 1989, Gholam A. Peyman was granted a US patent for LASIK
What Are the Advantages of LASIK Eye Surgery?
Around 90% of patients will have their desired vision after LASIK. An enhancement can further increase this number.
LASIK is associated with very little pain.
Vision is corrected nearly immediately or by the day after LASIK.
No bandages or stitches are required after LASIK.
Adjustments can be made years after LASIK to further correct vision.
After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.
Preoperative procedures:
Contact lenses
Patients wearing soft contact lenses are instructed to stop wearing them 5 to 21 days before surgery.
Pre-operative examination and education
In the USA, the FDA has approved LASIK for age 18 and over.[21] More importantly the patient's eye prescription should be stable for at least one year prior to surgery. The patient may be examined with pupillary dilation and education given prior to the procedure. Before the surgery, the patient's corneas are examined with a pachymeter to determine their thickness, and with a topographer, or corneal topography machine,[1] to measure their surface contour. Using low-power lasers, a topographer creates a topographic map of the cornea. The procedure is contraindicated if

    In 2001, Kwitko et al conducted a study to evaluate the efficacy of LASIK in the correction of residual refractive errors after penetrating keratoplasty. Fourteen eyes of 13 patients who had LASIK after PKP were retrospectively reviewed. At 12 months, mean myopia decreased from -5.33 D ± 4.22 to 0.19 ± 1.71 D, mean hyperopia decreased from +5.04 ± 3.32 D to +0.42 ± 0.46 D and mean astigmatism decreased from 5.37 ± 2.12 D to 2.82 ± 2.42 D. Retreatment was necessary in 42.9% of eyes because of cylindrical undercorrection. Uncorrected visual acuity improved in 11 eyes (78.6%). Best spectacle-corrected visual acuity improved in 6 eyes (42.8%) and was maintained in 4 eyes (28.6%); 5 eyes (35.7%) lost 1 Snellen line. Intraoperative complications…

    As optometrists, we always seek ways to improve primary eye care provisions to our patients. Primary eye care encompass from refractive services to the diagnosis and management of ocular pathologies. With the steadily evolving field of technology, eye care services are more fine tuned and this enable optometrists and other eye care practitioners to provide even better eye health services to patients. Though not many independent optometrists have the luxury of having some of the costly technology in the practices, I personally feel that they should be allowed to have easy access to them in order to provide the best patient management in their practice.…

    Case Study

    Dr. Mark Everett, clinic coordinator and optometric physician (OP) of the Pacific Cataract and Laser Institute (PCLI) office in Spokane, Washington, looked at the ad that Vancouver, Canada-based Lexington Laser Vision (LLV) had been running in the Spokane papers and shook his head. This was not the first ad nor the only clinic advertising low-priced LASIK eye surgeries. Dr. Everett just could not believe that doctors would advertise and sell laser eye surgery based on low price as if it were a stereo or a used car. The fact that they were advertising based on price was bad enough, but the price they were promoting–$900 for both eyes–was ridiculous. PCLI and its cooperating optometric physicians would not even cover their variable cost if they performed the surgery at that price. A typical PCLI customer paid between $1,750 and $2,000 per eye for corrective laser surgery. Although Dr. Everett knew that firms in Canada had several inherent cost advantages, including a favorable exchange rate and regulatory environment, he could not understand how they could undercut PCLI's price so much without compromising service quality.…
