We Let You See The Future

When you choose NVISION® for your eye care, you can always count on experienced surgeons and advanced technology.

The VISX Star S4 1R® Excimer Laser

The Wavescan Aberrometer measures your eyes’ lower and higher order aberrations (optical imperfections) – which are unique to your eye, much like your fingerprint. That information is used by the Visx Laser to customize your treatment for your eyes only. This customized wavefront-guided laser vision correction procedure reshapes your cornea, giving you a higher-quality, optically-improved vision outcome.

The Wavelight® EX500 Excimer Laser

The Wavelight® EX500 Excimer Laser is used for Wavefront-Optimized, Wavefront-Guided and Topography-Guided Excimer Laser Treatments (CONTOURA). The fastest laser in the United States, the Wavelight® EX500 also has the fastest tracker in the world. The benefit to you is better predictability, with more than 98% of our patients getting 20/20 vision, with both eyes open, and higher quality of vision—plus better comfort since the treatments are so fast. Topography-Guided Excimer Laser Treatments (CONTOURA) are the latest innovation in Laser Vision Correction. Topographic measurements based on your unique corneal imperfections are used to achieve a more personalized treatment than with conventional LASIK treatments. In the FDA clinical trial, two-thirds of the patients had uncorrected vision that was one or two lines better than 20/20 vision, and 40% had better uncorrected vision than they have ever had with glasses and contacts.

Femtosecond Laser Technology

The Femtosecond Laser replaces the blade commonly used to create the LASIK Flap. Using a computer-guided laser makes the procedure safer and more precise than the blade. All parameters of the flap can be customized for your eyes to deliver speed, accuracy, precision and improved safety. Compared to the blade, it allows your surgeon to treat a wider range of prescriptions because the depth of the flap can be customized for you.

The Femtosecond Laser delivers micron-level accuracy by separating the natural layers of the cornea with the creation of a rapid succession of microscopic bubbles. Your surgeon will use the Femtosecond Laser that is best suited for your eyes to give you the safest, most precise outcome.

Ziemer Line Technology

The Ziemer Laser is used to create the LASIK flap, and allows surgeons to precisely customize the flap—including shape, size, thickness, orientation and side contours.

The Ziemer laser is also used for:

Creating the channels for INTACS® in Keratoconus surgery
Creating the corneal pocket for KAMRA® and Raindrop® Inlays for the treatment of Presbyopia
Creating partial or full thickness corneal transplant resections

NVISION® was the first laser eye center in the Western United States to offer this advanced Swiss technology. It offers the highest speed and lowest energy output of any Femtosecond laser, making it the most comfortable for our patients during surgery. It also offers a rapid recovery of the highest-quality vision.

Zeiss Femtosecond Laser

The Zeiss Laser is the only laser with the technology to perform the SMILE procedure—laser vision correction without the need of a flap or an Excimer Laser. This German-made laser offers several technological advantages, including being the first of its kind to offer a curved corneal interface which gives our patients the most comfort during flap creation. Our patients feel absolutely nothing during flap creation with this laser.

Intralase IFS Femtosecond Laser

IntraLase was the first laser company in the world to develop the Femtosecond Laser. iFS IntraLase is a new, fifth-generation US-made laser. The Intralase Laser can also be used for INTACS®, Corneal Transplants, and Corneal Inlays for Presbyopia.

Femtosecond Laser Technology For Cataract Surgery

NVISION® was the first to use this technology in California. Femtosecond lasers automate many of the most challenging steps in cataract surgery that are typically performed using a blade or performed manually. Since these lasers are all computer controlled, your surgeon will customize the laser treatment for your eyes only. These steps include creating the primary entry incision of the cornea, the correction of astigmatism, the creation of the capsular opening—considered by most to be the most critical part for the safety of the procedure—and the fragmentation of the crystalline lens. Since all these steps are computer-controlled with micron accuracy, we believe that using the laser vs. manually performing these steps makes your cataract procedure safer and more precise.

Wavetec Ora Technology

NVISION® was the first to use this technology in California. This revolutionary technology, attached to the surgical microscope, allows your surgeon to use advanced optical aberrometers to measure the power of the replacement intraocular lens during surgery after your lens has been removed. This, we believe, gives you the best chance of having excellent uncorrected vision, maximizing the chance for freedom from needing glasses after surgery. It is especially useful for eyes that have had corneal surgery before—such as LASIK, PRK, or RK, and for patients with extreme levels of nearsightedness, farsightedness, and astigmatism.

HD Analyzer and Acutarget HD

NVISION® was the first in California to use this technology to implant the KAMRA® corneal inlay to minimize or eliminate the need for reading glasses. Using complex advanced optical physics, optical scatter is measured to: 1) determine tear film stability, 2) determine the presence of subtle crystalline lens changes that are not detectable by the human eye which may be the reason for reduced quality of vision from early cataracts, and 3) determine the position of the KAMRA® inlay for optimal quality of uncorrected distance and near vision.

ITRACE Technology

The only device of its kind using ray-tracing technology and sophisticated optical physics technology that has the capability to give your surgeon the ability to determine whether your symptoms of reduced quality of vision are secondary to corneal pathology or lens pathology. This helps your surgeon determine whether lens replacement is the procedure of choice for you vs. laser vision correction.

ORBSCAN Technology

Optical Topography is used by your surgeon to measure your corneal thickness distribution, your corneal shape and corneal elevations. This technology is crucial in determining your candidacy for laser vision correction.

PENTACAM Topography

This device precisely maps the corneal surface contour and measures the thickness distribution, as well as the underlying layers of the cornea. It is the first of its kind to measure the actual elevation and thickness, other aspects of the front part of the eye such as the lens density, and the contour and anatomy of the front part of the eye. It is used to determine candidacy for laser vision correction and cataract surgery. The Pentacam is also used for intraocular lens calculations to determine the power of the intraocular lens to be implanted, as well as the orientation and magnitude of astigmatism to be corrected during cataract and Dysfunctional Lens Exchange Surgery.

Optical Coherence Tomography

This technology has revolutionized all aspects of ophthalmology. With resolution millions of times more precise than CT or MRI, the internal structures of the eye such as the retina, macula, and optic nerve can be imaged and analyzed at a cellular and cell layer level. This information is critical to determine candidacy for cataract surgery as well as laser vision correction. It’s also critical in assessing other aspects of general health and nutrition. This device also provides the same level of detail about the cornea and its cell layers.

Specular Microscopy

This is a non-invasive photographic technique that allows visualization of the corneal endothelium—the cell layer of the cornea that maintains its clarity. The corneal endothelial cells are individually photographed, giving us information about the density, size and shape of the cells, which has profound implications in cataract surgical planning.

IOL Master and Lenstar

Both devices are used to measure several aspects of the eye length, placement of the crystalline lens and the corneal curvature. This information is used to precisely measure the power of the intraocular lens, as well as the magnitude and orientation of astigmatism correcting intraocular lenses used in cataract and Dysfunctional Lens Exchange Surgery
