What is LASIK?

LASIK is a remarkable surgical procedure that corrects nearsightedness (myopia), farsightedness (hyperopia) and astigmatism in mere minutes. This is done safely and precisely by reshaping the cornea with a laser. Many of Dr. Pyfer’s patients are already enjoying the benefits and freedom of natural 20/20 vision or better after laser vision correction.

Lasik is the most commonly preformed elective procedure in America. Dr. Pyfer is proud to offer the latest state-of-the-art technology available in refractive surgery. Lasik combines the advantages of two sophisticated technologies: the safety of the All Laser Intralase Blade Free technology for the flap creation, and the precision of the Custom Wavefront Guided technology to reshape the imperfections and refractive errors on the cornea. Together, these two advances in technology allow Dr. Pyfer to achieve your best corrected visual acuity in mere minutes. Thanks to LASIK, millions of people worldwide have experienced the wonder of clear vision without the help of glasses or contact lenses.

Intralase - All Laser Lasik - Blade Free

Dr. Pyfer was the first surgeon to perform All Laser Intralase Blade Free Lasik at Wills Eye Hospital in Bucks County. Intralase Lasik offers many improvements over other refractive surgery procedures. A coined term has developed from these improvements; it’s known as the “WOW effect”. Patients are often able to see 20/20 or better the very next morning, and this eye opening experience literally makes them say, “WOW”! Thus coining the term at Northern Ophthalmic Associates, “The WOW effect”. Further examples of improvements with Custom Intralase Lasik include the elimination of halos, glare, and night vision issues, little or no post-operative discomfort, immediate vision improvement, decreased light sensitivity, and the ability to drive and return to work as soon as the next day.

Our focus is on safely achieving your best corrected visual acuity. We encourage you to ask our team members how you can find out if one of our many refractive procedures could achieve your best high-definition vision too!

Custom Wavefront Technology

Wavefont technology makes it possible to perform customized refractive surgeries using information gathered from the patient's own eyes. This allows us to correct the very specific refractive errors that obscure each patient's vision, so patients enjoy the best vision quality possible.  Using CustomVue Intralase technology eliminates visual side-effects like halos, glare, and starbursts around lights and other night driving issues. Many compare the results after custom wavefront technology to “HD - high definition” vision. 

During the pre-operative examination, we collect a set of measurements called a wavefront. Data from the exam is converted into a waveprint -- a unique profile of your optical system that is as personal as a fingerprint. The laser then maps the information in your waveprint onto your cornea, reshaping it for unparalleled vision improvement.

Am I a candidate?

lasik, lasekNot everyone is a good candidate for LASIK. When you come in for an evaluation, Dr. Pyfer and his team will conduct an extensive eye exam to determine whether LASIK or another refractive procedure is appropriate for you and your ideal lifestyle. Dr. Pyfer offers informative seminars and complimentary consultations.   


What happens during the procedure?

The procedure is preformed at one of our Wills Eye locations.  During the LASIK procedure, Dr. Pyfer uses the Intralase Laser to create a thin flap on the surface of the cornea.  The flap is described as having a horseshoe shape; the top of the flap remains untouched acting as a hinge for the flap.  The flap is then delicately lifted so the computer-controlled excimer laser can begin reshaping the cornea's curvature to correct the vision. The flap is then gently guided back into placed, instantly adhering without the need for stitches. The procedure takes only 15 minutes, with the laser actually activated for just 10-60 seconds per eye.  Clear vision and comfort is achieved rapidly in most cases, usually by the next morning. A common sensation shortly after surgery is light sensitivity and a dry eye sensation, but this is minimal and subsides quickly with medication eye drops and lubricating drops.

What is Epi-LASIK, ASA & PRK?

Dr. Pyfer was the first surgeon to perform Epi-LASIK and Custom Wavefront Guided Intralase All Laser Lasik at the Wills Eye Surgery Center in Bucks County, and he has extensive experience with this new blade-free technique to help assure your comfort and safety.

Epi-LASIK, also known as, ASA and PRK are recommended alternatives to LASIK when there is not enough corneal tissue to safely create the corneal flap or when one’s lifestyle does not allow for the adequate eye protection needed during the healing period for Lasik. Like LASIK, Epi-Lasik reshapes the cornea with a laser to correctly improve vision. However, instead of making a flap on the cornea, with Epi-LASIK the surgeon uses a fine instrument to remove only the very thin layer of surface cells, called the epithelium. These cells regenerate quickly, over a period of 3-5 days in most cases. The excimer laser is then applied, just like with LASIK, to reshape the cornea and correctly refocus the vision.

Epi-Lasik is also recommended for law enforcement or military personnel who cannot adequately protect their eyes during the healing period needed for LASIK. The lasting 20/20 results are the same as with Lasik, but the healing process is a bit longer.

Visian ICL

The Visian ICL™ by STAAR Surgical is an Implantable Collamer Lens used to correct myopia (nearsightedness) in adults without altering the cornea. It is the only minimally-invasive foldable lens available in the U.S. Made of a patented collagen-containing material called collamer, the Visian ICL is highly biocompatible, meaning it can be implanted in the eye with minimal risk of rejection.

Under topical anesthesia, the ICL and a gel-like substance is placed behind the iris through a tiny incision in the cornea. The gel is then removed. The procedure takes about 15 minutes and no stitches are required.

The ICL's location allows it to provide excellent quality of vision and also ensures that it is invisible to others. The ICL can be removed or replaced at any time, and patients can wear glasses or contact lenses or choose to have other procedures done with the ICL in place.

Reading Vision KAMRA


Frustrated by reading glasses? Can’t ever seem to find a pair when you need them? End the hunt. Contact us today for a complimentary consultation to see if you’re a candidate for an advanced solution to reading glasses!

Enjoy Life without Depending on Reading Glasses

The KAMRA inlay treatment is an eye procedure that restores near vision and frees you from the constant frustrations of reading glasses. It is ideal for active people looking to no longer depend on reading glasses or contact lenses for their everyday activities. The KAMRA inlay:

  • Restores everyday vision so you can see text messages, a computer screen and the time on your wrist watch, without the frustration of reading glasses
  • Provides a natural range of vision – from near to far – without blurry zones
  • Offers a long-term solution that will help you enjoy clear near vision over time

Why is My Near Vision Changing?

In our 40s and 50s, we begin to experience the naturally frustrating effects of blurry near vision. Reading the newspaper, seeing the computer screen or sending a text message becomes a struggle. We end up depending more and more on reading glasses or contact lenses to see up close. This natural loss of reading vision is called presbyopia (prez-bee-OH-pee-ah), and it eventually affects all of us, even if we never needed vision correction before.

How the KAMRA Inlay Works

The KAMRA inlay sits in the first few layers of the eye known as the cornea. Smaller and thinner than a contact lens, the inlay is a mini-ring with an opening - or pinhole - in the center. This pinhole allows only focused light to enter your eye. The KAMRA inlay is placed in only one of your eyes, allowing you to see up close, while maintaining your distance vision in both eyes. Your non-KAMRA eye is left untouched. Working together, the eyes allow you to see near-to- far. This is unlike monovision laser vision correction, which corrects one eye for near and one eye for distance and does not last over time.

How Do I Know What is Right for Me?

The procedure recommended, if any, is customized for every patient, and can only be determined during an extensive ocular evaluation with Dr. Pyfer and his staff at either our Jenkintown or Wills Eye locations. The refractive consultation is free, and it is the best way to determine if laser vision correction can enhance your lifestyle like it has so many others.  If you would like to learn more or are ready to take the next step toward a clearer tomorrow please call 215.885.6830 to contact, Laura Arruda, our Refractive Coordinator.  We look forward to helping you achieve your best vision!
