For more than 40 years, central Pennsylvania has looked to Memorial Eye Institute for the most advanced technologies and techniques in eye care and eye surgery. Memorial Eye Institute has built its leading edge reputation by always being ahead of the curve for its patients. Memorial Eye was Pennsylvania’s first fully approved and accredited outpatient ophthalmic surgery center. It was central Pennsylvania’s first Laser Vision Correction center and Pennsylvania’s first ALL-LASER LASIK facility. Memorial Eye Institute is one of a select group of centers nationwide to be recognized by TRUSTED LASIK SURGEONS, a professional group of the nation’s most experienced and exceptional laser vision correction and lens implant surgeons.

One of the most popular ways to correct vision is with a procedure called LASIK (Laser In-situ Keratomileusis), which uses an Excimer laser to change the curvature of the cornea (outer window of the eye). LASIK is the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. In fact, most LASIK patients notice a significant improvement in their vision soon after surgery. LASIK removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism.

LASIK is for those who:

  • want to reduce or eliminate their dependence on glasses or contacts
  • are at least 18 years of age
  • have had a stable eye prescription for at least one year
  • have no health issues affecting their eyes
  • have no signs of glaucoma or cataracts

The ALL-LASER Approach

ALL-LASER LASIK is available at Memorial Eye Institute. It combines two exciting technological advances that offer patients the best possible chance for excellent visual outcomes, and the highest quality vision possible. These technological advances are: the WaveLight FS200 femtosecond laser and the WaveLight ALLEGRETTO WAVE Excimer laser, utilizing wavefront principles in each and every procedure.

Since the Excimer laser’s approval by the FDA in 1995, millions of people have eliminated their nearsightedness, farsightedness, and astigmatism, and their dependence on glasses and contact lenses.

The FS200 laser is focused to a precise depth within the cornea.

Excimer lasers differ in a number of ways, but conventional Excimer laser treatment uses the same formulas to treat every person with the same optical prescription. With the advent of wavefront-guided custom treatment in 2002, we can address the unique imperfections in each patient’s optical pathway. Today, our LASIK patients have the opportunity to improve the quality of their vision beyond 20/20.

Making The Corneal Flap

LASIK involves making a flap in the cornea and reshaping its inner tissue. Our WaveLight FS200 femtosecond laser adds a tremendous amount of precision and safety by using a laser (not a blade) to create the LASIK flap. The FS200 laser directs a laser beam into a tiny two-micron size spot of energy. The beam passes harmlessly through the outer layers of the cornea until it reaches its exact focal point within the cornea. In approximately 6 seconds, with computer precision, the FS 200 delivers over a million pulses as it separates the layers of corneal tissue and creates a customized flap of the desired thickness, size, orientation, and location. After treatment, the flap is folded back into its original position where it bonds without the need for stitches.

This unprecedented level of control makes LASIK safer and allows more patients to qualify for LASIK. The level of accuracy, precision, and control with the FS200 laser is simply impossible to achieve with a mechanical microkeratome.

High-Quality Vision

After making the corneal flap with the FS200 Excimer laser, the eye is reshaped with the ALLEGRETTO WAVE, one of the fastest Excimer laser system in the world, with an average patient treatment time of less than 30 seconds. Its flying-spot laser beam is less than 1mm wide, which allows Dr. Chotiner to finely sculpt the cornea with precise accuracy. Its ‘PerfectPulse Technology’ ensures that every laser pulse has ultra-stable energy levels and is placed exactly where it belongs.

Such a high-speed laser must also have an ultra-fast eye tracking system to follow eye movement during the procedure. Using three independent infrared light sources, the ALLEGRETTO WAVE will automatically pause the treatment if the eye moves out of range and resume treatment when the eye is back in position.

Understanding that all eyes are not the same, the ALLEGRETTO WAVE takes into consideration each patient’s individual corneal steepness and automatically compensates for laser energy that can be lost in the periphery of the cornea due to each individual eye’s natural shape. In doing so, the ALLEGRETTO WAVE specifically addresses the spherical aberrations (visual distortions) that cause glare and can influence night vision.

Patient Benefits

The precision of All-LASER LASIK with the FS200 and ALLEGRETTO WAVE lasers virtually eliminates many of the complications associated with the conventional approach.

  • Custom-tailored precise corneal flap creation, especially important for patients with thin or misshapen corneas
  • Safer intra-operative procedure
  • Less worry about surgical complications
  • Reduced risk of unwanted visual side effects such as glare and halos
  • More likely to achieve 20/20 or better vision


We’ve invested in the FS200 and ALLEGRETTO WAVE lasers because our patients are worth it. With one of the widest ranges of treatment approval, we can offer this new generation technology to the majority of our patients, including those with high levels of nearsightedness and farsightedness.

We offer a number of finance options and affordable payment plans. It is easy to apply online and receive credit approval before you schedule an appointment.
