Custom LASIK

WavescanThere are many different names and brands associated with LASIK and Laser Vision Correction It has become increasingly more difficult for patients in the Orlando area to understand exactly what procedures and technologies will be best suited for them as they move forward with their vision correction decisions. Common misconceptions often occur when discussing Custom LASIK.

With Custom LASIK, we take more measurements and create a procedure that is more specific to your unique eyes. Measuring subtle differences in the cornea (surface of the eye where the procedure is done) by using advances in Cornea Topography is just the beginning of having a LASIK procedure custom-made for you. Dr. Herschel takes great consideration in evaluating all of your preoperative measurements, the health of the surface of your eyes (cornea) as well as intraocular complexities during your evaluation. As a Cornea specialist with over 25 years of vision correction experience, he believes in taking the time to see all of his patients personally to consider and evaluate all the detailed components in your vision and discussing your options prior to scheduling your procedure.

At Herschel Lasik at Magruder Eye, our mission is to deliver results you deserve and expect from your vision correction procedure. By utilizing sophisticated technology and his vast experience, Dr. Kelly Herschel is able to map the unique details of your eyes allowing him to customize your LASIK procedure.

In addition to customizing your preoperative and surgical treatments for more accurate results, Dr. Herschel has the ability to customize the first step of your laser procedure, creating the corneal flap, by using the Ziemer Femto LDV™ laser. Traditionally the first step of LASIK involved using a microkeratome. The microkeratome is a mechanical device which has been used successfully in millions of procedures but it has some limitations. By using the Ziemer Femto LDV™, Dr. Herschel is not restricted to some of the limitations by the mechanical microkeratome (which is not used at Herschel Lasik).

The Ziemer femtosecond laser allows for detailed customization during the creation of the corneal flap for your eye’s unique needs. It has made successful LASIK possible for many more people than traditional LASIK. Using our pre-operative measurements in conjunction with the Femtosecond laser allows Dr. Herschel to truly deliver a fully customized procedure from beginning to end to insure you get your personal best visual result.

Advantages of the Femtosecond laser:

Safer, Programmable and more Precise:

  • The Ziemer FemtoLDV™ uses a 100% blade-free technique used to perform the critical first step in the LASIK procedure: creating the corneal flap. Unlike the Microkeratome which uses a blade to create the flap, the Ziemer uses tiny, rapid pulses of laser light to create the corneal flap during the first step of LASIK. Each pulse of light passes through the top layers of the cornea and forms a microscopic bubble at a specific depth and position within your eye that is determined by the doctor allowing the flap to be created without any cutting. While no procedure is without risk, the Ziemer does help eliminate complications which can occur from the mechanical bladed device.
  • Because of the unique way in which the Ziemer laser creates a precisely positioned layer of bubbles just beneath the surface of your eye, it creates a smooth even surface after your flap is lifted. With the Ziemer femotsecond laser, a blade never touches your eye.


  • Because the Ziemer is computer guided it allows the doctor to customize the first step-the flap creation. The doctor can program the size and shape of the flap allowing Dr. Herschel to meet each patient’s individual requirements for treatment. A customizable flap also allows for treatment of patients that might otherwise have to consider PRK or be a non candidate for traditional LASIK. The Ziemer allows Dr. Herschel to truly customize every step of the patient’s procedure.

After the flap is created, in the second step of your LASIK procedure,The WaveLight® Allegretto Wave® Eye-Q Laser  treats the bed of the cornea based on your pre-operative measurements and prescription. 

The WaveLight® Allegretto Wave® Eye-Q Laser was designed based on an idea that was once only imagined: a system with shortened surgery times, innovative and reliable eye-tracking, and a clear ergonomic concept.

  • High Speed 400HZ Eye Tracker adjusted to the high speed of the laser beam actively tracks the fastest eye movement and verifies location before releasing pulses.
  • Thermal Optimized helps minimize the potential for thermal buildup.
  • Cross line projector provides precise centration

Unlike earlier technology, the Wavelight Allegretto Wave Eye-Q laser was designed to preserve th natural curvature of your eye. As a result, LASIK with Wavelight refractive technology can help preserve the quality of your vision, ensuring your eyes are their most natural and their most useful. 

It's a matter of what we feel is best for our patients. Why we dont' use a microkeratome; the limitations:

The microkeratome is a hand-held mechanical device which contains a steel blade that moves back and forth and creates a flap as it travels across the cornea or the watch glass front of the eye. A microkeratome is only capable of making a single, one-dimensional plane across the cornea. As it oscillates back and forth, sometimes it can leave an irregular surface after the flap is lifted compared to the Ziemer laser. This can contribute to your quality of vision after your procedure.

Unlike with the all laser LASIK procedure with the Ziemer laser, the doctor does not have the ability adjust the microkeratome to make a thinner flap needed for some patients. In the past, those patients had only the option of PRK or what we call surface treatment. While PRK is an excellent blade free procedure that Dr. Herschel performs routinely for patients and produces excellent results, the recovery is slower and can have discomfort. For some people, the time frame to recover with PRK is not workable with their lifestyle needs.

While the microkeratome is a safe device in the hands of a skilled surgeon such as Dr. Herschel, and has been used in millions of LASIK cases, it again is a blade and when complications occur with the blade (which are probably 1 in 5000), these complications can be problematic, can effect visual recovery and the procedure cannot be repeated/completed again for at least 3-6 months.

Dr. Herscel prefers the safety and efficacy of the Zeimer laser for flap creation over the older Microkeratome technology.
