Unlike LASIK, the iLASIK procedure is entirely bladeless, utilizing only our advanced laser technology. iLASIK uses an iFS Advanced Femtosecond Laser to create an ultra-precise, thin flap in the uppermost layer of the cornea, which is folded back to expose the underlying corneal tissue. Guided by a highly precise wavefront map of the surface of the eye, the CustomVue® laser is then used to reshape the cornea. This process is aided by VISX® Iris Registration tracking technology, which maintains alignment of the customized wavefront corrections. The entire surgery typically lasts between 10 and 15 minutes, with total laser time usually lasting between 30 and 45 seconds per eye.

While patients who undergo traditional LASIK have to wait for their blade-created corneal flap to heal, most patients who undergo iLASIK with IntraLase® are able to return to work the next day.

The Eye Institute has upgraded its iLASIK technologies to include the iFS Advanced Femtosecond Laser. This laser technology is used in lieu of a metal blade for the crucial step of creating the LASIK flap in the cornea. Our experience with the bladeless IntraLase® system has been exceptional. Now, the Black Hills Regional Eye Institute has the most current, fifth-generation laser eye surgery system. This laser technology offers several improvements to the Rapid City community:

10 second flap creation leading to less risk of flap complication and increased safety for the eyes

We have had excellent results with iLASIK. We're proud to be the only clinic in the region performing iLASIK with the iFS Advanced Femtosecond Laser. With the iLASIK procedure, you can count on a procedure tailored to you, your vision, and the unique characteristics of your eyes. 3-D Custom WaveScan® mapping, precise measurement, and the use of two of the most advanced lasers (iFS Advanced Femtosecond Laser and VISX CustomVue®) differentiate the iLASIK procedure from all others.


The LASIK Procedure: Step-by-Step


iFS Advanced Femtosecond Laser

Replacing the handheld microkeratome blade with laser technology improves safety by eliminating virtually all of the most severe, sight-threatening flap complications. Patient measurements guide the computer-driven laser to create a customized corneal flap with micro-precision, while simultaneously preparing an optimal corneal surface below the flap for better visual outcomes. The iLASIK procedure is the first to incorporate two lasers with the ability to tailor a patient's laser vision correction to each individual eye from start to finish. This laser technology has truly revolutionized the way laser vision correction is performed.

Excimer Laser Technology

The crown jewel of the customized iLASIK procedure is the Advanced CustomVue™ procedure using the VISX™ Star S4 Excimer Laser Technology, which stands in a class of its own with the broadest range of FDA-approved indications of any technology. Excimer laser technology has the unique ability to remove exceptionally fine layers of surface material with almost no heating and without affecting surrounding tissue. Incorporating the precision of wavefront guidance, the Advanced CustomVue™ LASIK procedure treats low-to-severe nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.


All surgical procedures involve some degree of risk. In the correct patient, the risks of LASIK are outweighed by the benefits. Some of the risks of LASIK are:
