Donelson Eye Associates' LASIK Technology

Most of the questions we hear about LASIK revolve around the cost, procedure, or outcomes available to the patient. One of the most important aspects to LASIK – the technology used – is often never addressed. However, knowing the difference between state-of-the-art technology and older methods will help you understand the results and outcomes you can expect from a specific surgeon or LASIK practice.

Since Donelson Eye Associates is owned by Dr. Donelson, he has the ability to choose the top technology that will achieve optimal results for his patients.

Each generation of newer technology works to improve issues that earlier technology could not address. The lasers used today at Donelson Eye Associates achieve significantly better results, with greater patient comfort than earlier systems.

The combination of the Intralase™ laser and the VISX S4 IR™ excimer laser produce the best results Dr. Donelson has ever achieved.

All-Laser LASIK with the IntraLase Laser

The flap-creation step in earlier LASIK procedures was performed using a spinning hand-held blade called a microkeratome. The invention of the blade-free IntraLase system has resulted in greater accuracy and more patient comfort. In addition, the healing times with the IntraLase are faster than when using the microkeratome.

Reshaping the Cornea with the VISX S4 IR

Earlier excimer lasers achieved startling results, but they were occasionally accompanied by night vision issues and their technical limitations meant that some patients could not be considered good candidates which prevented many would-be LASIK patients from enjoying the benefits of the procedure.

As a commitment to the best possible outcome for every patient, Dr. Donelson has chosen to use the VISX S4 IR excimer laser.

VISX S4 IR Excimer Laser*

  • Iris Registration (IR): The first FDA-approved, fully automated, non-contact method of alignment of the correct CustomVue treatment to the corneal site
  • Variable Spot Scanning (VSS): Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times
  • ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements—no dilation required
  • ActiveTrak Automatic Centering: Locates, and then automatically sets the treatment center to the ­center of the pupil.
