What is a cataract?

Described as a natural clouding of the eye lens, cataracts are a normal part of life; in fact, if you live long you will eventually experience the onset of cataracts. Cataracts affect a very large percentage of people over the age of forty to fifty-five years old. The natural eye lens is made of similar material that comprises our fingernails and our hair. Just like fingernails often get brittle and hair goes gray, the natural eye lens will stiffen and get cloudy due to the normal aging process. In fact, half of all Americans have them—or have had cataract surgery—by age 80. Cataracts are not preventable, but they are treatable and our very experienced San Antonio cataract surgeon, Greg Parkhurst MD can discuss your options with you, so you see better after cataract surgery.

In this video, Dr. Parkhurst discusses the honor of performing his parents’ vision correction procedures, including his father’s Modern Cataract Treatment.


There are many things that you need to know once you are diagnosed with cataracts. First, you will need to see an Ophthalmologist, like Dr. Parkhurst who will need to confirm the diagnosis and determine how soon the cataract will need to be removed. You should plan to discuss what happens during cataract surgery with your surgeon. Greg Parkhurst MD is a very experienced surgeon and he will walk you through the entire process. You will also need to discuss your lens implant options. Cataract patients now have multiple options for seeing after cataract surgery. The differences typically involve one distance or multiple distances. There are monodical and multifocal lens implants to discuss. If cataracts are preventing you from seeing, call Parkhurst Nu Vision today for a complete cataract evaluation.

Many patients think that a cataract is some sort of film that spreads over the surface of the eye. In reality, a cataract is a naturally occurring change in the eye, which is a gradual clouding that makes vision less sharp over time. Patients typically report the sensation of looking through wax paper, they often have trouble driving at night and colors seems very dull. The eye works much like a camera, and like a camera, the lens must be very clear to see well. A healthy transparent lens absorbs light and accurately focuses it onto the retina, providing a crisp clear image. As the aging process takes hold of our eyes, proteins begin to clump together forming opaque clusters. Over time, these protein deposits eventually cloud the entire lens allowing significantly less light to pass through. The small amount of light that does make it through is diffused or scattered, leaving vision defocused. These protein clusters can also change the color of the normally clear lens making it a yellowish brown color.

When is the best time for cataract surgery?

Cataract surgery is a medical procedure that needs to be done when the cataract becomes cloudy and starts to impair vision. The decision to undergo cataract surgery is one that needs to be made with your family eye care provider and surgeon, and one that should be made together. Sometimes, a surgeon may suggest waiting for surgery, and this will not hurt your eye. However; considering the benefits of this procedure, it is a decision most of our patients make once they have been diagnosed.

5 Common Vision Problems From Cataracts

  1. Trouble driving at night, glare from headlights.
  2. Having trouble determining shades of colors.
  3. Cloudy vision or sometimes even blurry vision.
  4. Sunlight can often appear too bright to handle.
  5. Frequent changes in eyeglass prescription.

People who are looking to undergo cataract surgery at a practice in the San Antonio, New Braunfels, Corpus Christi, and Uvalde areas, will find the region’s premier surgeon and facility at Parkhurst-NuVision. Contact our office today to schedule a consultation. Cataract patients throughout the greater San Antonio area now have access to an all-laser, blade-free method of cataract surgery that is revolutionizing one of the most common procedures performed in medicine today, according to eye surgeon Gregory D. Parkhurst, MD, Medical Director and Founder of Parkhurst NuVision, who recently performed the first official LENSAR laser cataract procedure in San Antonio.

Femtosecond laser cataract surgery using the LENSAR laser system offers a reproducible, noninvasive technique to replace the least predictable – and most technically demanding – steps for surgeons during conventional cataract procedures.”Our LENSAR laser procedure is truly a technological breakthrough in precision, accuracy, and safety for today’s cataract patients,” said Dr. Parkhurst, who performed the first LENSAR laser cataract procedure on Daniel Von Brown on Friday, October 24, 2014.

“As the fastest growing femtosecond cataract laser company, we are looking for young, talented ophthalmologists to help the next wave of LENSAR Laser cataract surgeons integrate this technology into their practices. We are thrilled to have Doctor Greg Parkhurst and Parkhurst NuVision as one of our newest Centers of Excellence,” said Nicholas Curtis, CEO of LENSAR, Inc.”Now, not only will patients in San Antonio have an opportunity to receive the most advanced blade-free cataract procedure, but ophthalmologists worldwide will have the benefit of visiting Doctor Parkhurst’s best-in-class practice to observe the LENSAR Laser in action.”

Cataract removal and lens implantations are one of the most common – and successful medical procedures performed today. Each year, more than two million people in the United States have their vision restored through cataract surgery.

The LENSAR combines a state-of-the-art femtosecond laser, non-applanating patient interface, sophisticated software and a host of other unique features that allow Dr. Parkhurst to provide patients a gentle, highly customized cataract surgery with unprecedented precision and accuracy. “The LENSAR allows me to perform a more gentle method of cataract surgery because of a more efficient way of fragmenting the cataract and reducing the amount of energy needed to remove the cataract,” he said. “This results in less overall surgical time and a much healthier post-operative eye in general.”

“This femtosecond laser technology allows us to take an already safe procedure and make it even better by adding a new level of precision and predictability that is simply not possible with traditional manual cataract surgery,” said Dr. Parkhurst.

LENSAR System Cataract Surgery

Dr. Parkhurst is among the top 10% surgeons in the world to offer patients the safety, precision, and accuracy of the LENSAR Laser System. The LENSAR also makes laser correction of astigmatism now possible with a more precise and predictable laser-guided application. In the post-operative recovery period following laser cataract surgery, there is less incidence of swelling and inflammation than with traditional cataract surgery.

“What has been most impressed with the LENSAR system,” said Dr. Parkhurst, “is the advanced imaging this technology gives surgeons. For the first time in medical history, we’re able to precisely image the exact location, contour, and density of the cataract. LENSAR’s augmented reality technology allows us a build a sophisticated 3-D model of the true anatomy of each individual patient’s eye.”

The LENSAR laser procedure is surgeon-directed, computer-controlled and allows for added precision during surgery. This means patients can return to their normal activities sooner. Cataract development is simply part of the natural aging process and is quite common in everyone over age 50. Cataracts occur when the natural clear lens of the eye becomes progressively cloudy, causing colors to become less vibrant normal vision to become blurred. The only method to treat a cataract is through surgical removal of the body’s natural lens and implanting an artificial lens.

According to Dr. Parkhurst, cataract surgery has evolved over the years from a procedure with less than certain outcomes to an advanced no-patch, no-shot, no-stitch, 10-minute procedure with swift recovery time. “The LENSAR Laser is a perfect match with our state-of-the-art lifestyle lens implants that help reduce or eliminate dependency on prescriptive eyewear following cataract surgery.”

The LENSAR Precision Laser System allows Dr. Parkhurst to perform cataract surgery with accuracy up to 10 times greater than is possible with a manual cataract procedure. The reproducibility and accuracy of the LENSAR enhance the positioning of the artificial replacement lens. Dr. Parkhurst is recognized nationally as an expert and leader in cataract surgery and LASIK vision correction who has helped pioneer new trends in refractive surgery worldwide.

The Refractive Surgery Alliance (RSA) has also recently announced that Dr. Parkhurst has been awarded the RSA President’s Award for best-exemplifying the values and mission of the organization at the semi-annual RSA meeting in Chicago, Illinois.
