LASIK


CustomVue LASIK

What is LASIK?

LASIK Surgery is an in-office procedure performed at InVision by Dr. Stephen Johnson and Dr. Robert Deitch at their Indianapolis LASIK office.  Laser In-Situ Keratomileusis or LASIK, is the fastest-growing and most accepted form of laser vision correction.  LASIK can treat both nearsightedness and farightedness with or without astigmatism.  During the procedure, a delicate instrument - a microkeratome or an IntraLase laser, is used to create a very thin flap of corneal tissue.  Once this tissue flap is created, the surgeon positions the laser beam over the eye, directing light pulses to achieve the desired correction.  The flap is carefully put back in its original position.  Benefits of LASIK are many, including fast visual recovery, little or no discomfort, lower risk of haze, glare and halos, and most patients are very satisfied with the outstanding outcome results.  LASIK laser vision correction has quickly emerged as one of the true medical breaktrhoughs of modern history.  Dr. Johnson and Dr. Deitch perform Lasik at their Indianapolis LASIK facility and have treated thousands of Indianapolis LASIK Eye Surgery patients.

In the case of myopia (nearsightedness), the tissue removed is in the center of the cornea, which results in flattening of the cornea. For most patients, flattening of the cornea will allow incoming light rays to be focused on the retina. In the case of hyperopia (farsightedness), the tissue is removed in the periphery of the cornea, which results in a steepening of the cornea. This steepening is what allows patients to see clearly. It will also treat astigmatism at the same time by steepening the flatter meridian of the cornea and flattening the steeper meridian, bringing the light rays to one single point of focus on the retina.

The laser portion of the procedure takes from between 5 and 30 seconds depending on the level of myopia/hyperopia and astigmatism being corrected.  Once the doctor has completed this portion of the procedure, the flap is placed back down to its original position and allowed to dry for approximately two minutes. It takes around seven minutes to treat each eye. The corneal flap seals in its original position through osmotic and ionic forces. There are no stitches required in the operations.
 
 
The corneal flap becomes more secure the longer the period of time that has passed from the original procedure. The corneal flap can be relifted using special instrumentation up to 5-10 years after the initial procedure. After the first week, it is rare that the corneal flap will dislocate under normal circumstances.
 
 
One of the many advantages to the procedure is that if there is residual nearsightedness or farsightedness after the initial procedure, the flap can be re-lifted and additional laser treatment can be performed to treat this residual refractive error. This is called an enhancement. Enhancements are required between 2-5% of the time in our practice depending on the amount of original vision loss.
 
 
The greater the amount of refractive error preoperatively, the greater the likelihood enhancement will be necessary at some point following the procedure. Enhancements are required because the cornea did not fully respond to the original laser treatment or the effect of the treatment regressed. As living tissue, the cornea will vary in its response to the laser treatment from individual to individual.

WaveScan Wavefront System

Your vision is unique - as personal as your fingerprint or your DNA. WaveScan technology provides your eye doctor with a map of your eye.

WaveScan-based digital technology identifies and measures imperfections in your eyes 25 times more precisely than standard methods. The powerful WaveScan software translates the information into a set of CustomVue treatment instructions for the laser. The result is an optical “fingerprint” of the patient’s eye. These digital treatment instructions are then transferred to the laser, driving a new level of precision and accuracy.  This data is then used by the computer to correct all the optical aberrations of the eye during the procedure. No two treatments, like fingerprints, are exactly alike between patients or even between the two eyes of one patient!

This state-of-the-art laser has proven to have superior results. The eye tracker precisely follows tiny eye movements throughout the procedure so the laser delivers each pulse exactly where it is needed, resulting in an extremely smooth ablation. Should the eye move outside of the treatment area, the laser will automatically shut down. This allows for exceptional visual results.

Dr. Johnson and Dr. Deitch are Indianapolis LASIK surgeons who have adopted state-of-the-art technology in Custom LASIK Surgery, the VISX S4 Custom Vue LASER. They proudly perform refractive surgery procedures at InVision in Indianapolis using this laser, a revolutionary tool in laser vision correction.  VISX S4 Custom Vue LASER is safe, accurate, and has given a majority of its patients better than 20/20 vision.

What are the benefits of CustomVue?

The results of using the CustomVue procedure have been overwhelmingly positive with exceptional clinical results as shown by the findings below:

One year after the VISX CustomVue procedure:  

  • 100% could pass a driving test without glasses or contact lenses
  • 98% could see 20/20 or better without glasses or contact lenses
  • 70% could see better than 20/20 without glasses or contact lenses

Four times as many participants were very satisfied with their night vision after CustomVue, compared to their night vision with their glasses or contact lenses.

 

Am I eligible for the CustomVue procedure?

Though the CustomVue procedure allows more people to receive custom LASIK, there are certain individuals who are not good candidates for this procedure. You are probably NOT a good candidate for this treatment if you:

  • Are under 21 years old. At this age, your are still growing and are susceptible to change
  • Are pregnant or nursing. While pregnant, changes occur in your hormone system that can alter your vision. It's better to postpone the operation until after your child is born and after you are finished nursing
  • Are taking certain medications
  • Have high blood pressure
  • Thin corneas
  • Dry eyes
  • Glaucoma
  • Keratoconus (a corneal irregularity)
  • Eye inflammation
  • Herpes simplex
  • Suffered severe eye injuries in the past
  • Corneal infections or scars
  • Unstable refraction or refractive errors
  • Other diseases of the eyes such as AMD, Cataracts or others

Our physicians encourages you to speak with them personally to determine if you are eligible for the VISX CustomVue laser procedure.
