Intralase® iFS Laser System

The iFS® Laser is the 5th-generation femtosecond laser created by Abbott Medical Optics. This system gives the surgeon greater control for maximum customization — providing an indispensible tool for all-laser LASIK and beyond. With over 5 million procedures performed to date, IntraLase® Technology is the femtosecond technology of choice for LASIK.

Visx STAR S4 IR® Excimer Laser System

The most advanced excimer laser technology platform available today, the VISX S4 IR system seamlessly integrates data provided by the WaveScan WaveFront® System to deliver highly precise ablations for custom LASIK and PRK. With Iris Registration (IR), this system links the unique wavefront data of a patient’s eye (captured prior to surgery using the AMO VISX WaveScan wavefront system) with that eye’s live position and orientation seconds before the laser is engaged for LASIK or PRK . Since IR technology maps out multiple reference points specific to an individual patient’s iris and the VISX laser employs ActiveTrak 3-D active eye tracking during the laser treatment, the alignment and centration of custom LASIK and PRK are optimized and safety and treatment effect are maximized.

The AMO WaveScan WaveFront™ System

Advanced digital technology identifies and measures imperfections in the eye 25 times more precisely than standard refractive surgical methods, enabling the most custom procedure currently available for LASIK and PRK.

LenSx® Laser

The LenSx® Laser is a fully-integrated, image-guided femtosecond laser designed specifically for refractive cataract surgery. It automates many of the most challenging steps of cataract surgery using a customizable 3-D surgical platform.


Alcon CENTURION® Vision System

The CENTURION® is the only intelligent phaco technology that automatically and continuously adapts to changing conditions within the eye. It provides excellent anterior chamber stability, and places optimized energy technology at the surgeon’s fingertips through enhanced fluidic management during cataract surgery.

Micro Invasive Glaucoma Surgery

iStent is the first MIGS device that improves the eye’s natural fluid outflow to safely lower eye pressure by creating a permanent opening in the trabecular meshwork. Proven safe and effective, the iStent Trabecular Micro-Bypass:

  • Is safely implanted during cataract surgery
  • Spares important eye tissue that is often damaged by traditional surgeries
  • Does not limit treatment options that could help maintain vision and treat glaucoma in the future


iStent is the smallest medical device ever approved by the FDA. It is placed in a patient’s eye during cataract surgery and is so small that one can’t see or feel it after the procedure is over. iStent is designed to create a permanent opening in the trabecular meshwork, and works continuously to improve the outflow of fluid from the eye to help control eye pressure.

For patients with combined cataract and open-angle glaucoma, iStent reduces introcular pressure (IOP) by improving aqueous humor outflow. Inserted through a 1.5-mm corneal incision, iStent is the only FDA-approved device for the treatment of mild to moderate open-angle glaucoma.
