About LASIK Surgery
We move through a precise series of steps to ensure the safest, most effective surgical procedure:
- Laser vision correction treats vision problems like myopia and astigmatism using a state-of-the-art, computer-controlled excimer laser. This gentle beam of cool laser light carefully reshapes a thin layer of the cornea, flattening the curvature and improving the focusing problem. The term LASIK stands for "LAser in SItu Keratomileusis". This procedure utilizes the excimer laser and the microkeratome.
- Anesthetic eye drops are instilled in the eye, and then a suction ring is centered over the cornea ( the clear dome of the eye ). This suction ring stabilizes the position of the eye.
- The pressure increases, allowing the cornea to be held in place while the microkeratome operates. This device contains a sharp blade that moves back and forth at high speed. This process creates a partial flap of uniform thickness with a portion of the cornea left uncut to provide a hinge.
- The corneal flap is folded back on the hinge exposing the middle portion of the cornea. The excimer laser is then used to remove central corneal tissue and reshape the center of the cornea. The amount of tissue removed is determined by the amount of near-sightedness being corrected.
- Finally, the flap is placed back into its original position. The front surface of the eye is now flatter since the flap conforms to the underlying surface. The newly flattened cornea causes light to focus directly on the retina, thus correcting the previously existing nearsightedness.

Are You a Good Candidate?
You may be a good candidate for LASIK surgery if the following conditions are true for you:
- My prescription has not changed over the past 12 months
- My prescription is not greater than -8.00 Diopters of nearsightedness
- My prescription is not greater than +3.75 Diopters of farsightedness
- My astigmatism correction is not greater than -4.00 Cylinder with my nearsightedness
- My astigmatism correction is not greater than -2.75 Cylinder with my farsightedness
- I do not have recurrent eyelid infections or conjunctivitis
- My eyes do not feel dry or irritated throughout the day
- No degenerative eye disease was noted at my last exam
- I am not pregnant or likely to become pregnant over the next 12 months
- My occupation does not put me at risk for an eye injury
- My pupils do not seem larger than average
- It would be easier for me to participate in sports or daily activities without glasses or contacts
Limitations of LASIK
It is important to remember that LASIK does not correct presbyopia, the inability of the eye to focus on near objects. This condition usually occurs in a persons early forties and gradually worsens until around the age of sixty when it plateaus. Reading glasses or bifocals become necessary for computer use or other close work.
LASIK can make it difficult to accurately design an intraocular lens implant for patients undergoing cataract surgery.
Although LASIK is being performed frequently without any complications, there are still some risks associated with the surgery. Vision can become distorted due to irregularities in the cornea caused by wrinkling or swelling. the eye can become dry as a result of the procedure. In rare cases, the cornea has become too thin and begins to bulge. This will cause the eye to become nearsighted or astigmatic again. Some people experience fluctuation of their vision throughout the day, although in most cases this diminishes after a couple of months. Glare, haloes, and reduced night vision have also been reported by many patients.
