Dr. Wolfram Andrews

Dr. Wolfram Andrews was born and raised in Schwäbisch Hall, Germany. He traveled to the United States at a young age of 18 to begin a new and prosperous life. Settling in Columbus Ohio, Dr. Andrews graduated from The Ohio State University with a Bachelor of Science degree in Mathematics. He played 4 years on the varsity soccer team achieving Outstanding Sophomore status and was selected for the All-Midwest Team during his junior year.

Upon graduating from The Ohio State University, he began his optometric schooling at the Pennsylvania College of Optometry in Philadelphia. During his time in optometry school, he served as vice president of his class all four years, and was also an avid member of the student council. During his fourth year of optometry school, Dr. Andrews completed an externship program at the Baltimore Optometric Center where he treated many patients and became familiar with working in an optometric practice. In addition, he worked with Dr. Albert E. Wascou in New Holland Pennsylvania.

Andrews has traveled extensively to focus on global eye care. He went to Cap Haitien, Haiti in 1976 as part of his education to treat some of the various eye diseases of the Haitian people. In 1984, he journeyed to the Turks and Caicos Islands where he spent about two weeks flying to remote areas to deliver eye care to residents who had not had care in decades. Dr. Andrews enjoys annual mission trips to Guatemala where he provides eye care to missionaries and dozens of locals every year. He continues to serve also on a local level providing free eye exams and glasses to missionaries who are affiliated with his local church.

Once graduated as a Doctor of Optometry, Dr. Andrews decided to pursue his career in Lancaster County, Pennsylvania. He began moonlighting at several practice locations before he and Dr. Jay Stoltzfus opened their own practice known as Optometric Associates. The doors opened in May of 1981 with the desire to offer high quality care at reasonable prices to satisfy their patients needs. Today after more than 33 years of practice at the same location, the goal remains the same.

Dr. Andrews has extensive training in specialty contact lenses, detection and treatment of ocular disease, and geriatric eye care. He enjoys working with patients in a one on one setting and appreciates the small town feel of his practice. Many of his patients have been with him since the practice opened it’s doors.

He is a past president of the Kiwanis Club of New Holland, where he still attends weekly meetings after 26 years of membership. In addition he is a member of the American and Pennsylvania Optometric Associations. He currently resides in New Holland with his wife, Arlene with whom he has five children. He was thrilled to add his son Dr. Jonathan Andrews as an associate doctor at the practice in May of 2014.

When not at work, he enjoys being with his family, working out in the gym, and riding his motorcycle down to the beach. He is also delighted to spend time with his granddaughters, all under the age of two, and his Old English Mastiff named Brutus (after the Buckeyes, of course!).

Our Doctor Can Diagnosis and Treat Keratoconus

Your cornea is the transparent, outer lens of your eye, and it typically has a smooth dome shape. Keratoconus describes a condition in which the corneal structure isn’t strong enough to maintain a healthy ball shape.

Meet with our Keratoconus Specialist in New Holland, Pennsylvania to define your eye's condition and ways for treatment.

As a result, the cornea bulges outward into more of a cone. Our professional optometric team at our eye care clinic is knowledgeable about how to diagnose and treat keratoconus.

Keratoconus is rare, with an estimated one person out of every 2,000 having the condition. It generally appears in the teenage years and can progress slowly or rapidly.

Keratoconus also runs in families, so if you or your children are at risk, it’s advised to contact us for a thorough eye exam.

Causes of Keratoconus

Your cornea is held in place by very small collagen fibers. When they are weakened and too fragile, they aren’t able to preserve the round shape of your cornea.

A reduction in the protective antioxidants of your cornea, which act to destroy damaging by-products made naturally by corneal cells, is what causes keratoconus.

In addition to genetics, some types of eye injuries may increase your chance of being diagnosed with keratoconus.

Specific ocular diseases, such as retinitis pigmentosa, vernal keratoconjunctivitis and retinopathy of prematurity, as well as some systemic conditions (Down syndrome, Ehlers-Danlos syndrome, Leber's congenital amaurosis and osteogenesis imperfecta) are also associated with this corneal abnormality.

Our Keratoconus Specialist in New Holland, Pennsylvania has years of experience identifying the various levels of keratoconus and other corneal conditions.

Symptoms of Keratoconus

When the shape of your cornea begins to bulge, it alters your eyesight in two different ways. As the cone shape forms, your normally smooth corneal surface becomes wavy, called irregular astigmatism. Additionally, as your cornea expands, vision becomes increasingly nearsighted. Focusing becomes impossible without eyeglasses or contact lenses. Usually, the problems begin in one eye and develop later in the other eye too.

Typically, patient’s eyeglass prescription will change often as the vision becomes worse and contact lenses will be difficult to wear due to discomfort and improper fit.

When keratoconus become more severe (which usually takes a long time however on occasion can happen rather quickly), the cornea can begin to swell and form scar tissue. This scar tissue can result in even further visual distortion and blurred vision.

Altogether, these changes can create the following symptoms:

  • Blurred vision
  • Streaking of lights
  • Halos around bright lights at night; glare
  • Sudden change of vision in only one eye
  • Objects appear distorted, both near and distant
  • Double vision from just one eye
  • Triple ghost images

How We Diagnose Keratoconus

Our eye doctors will inspect carefully for the signs of keratoconus during your comprehensive eye exam. It’s critical to inform us of any symptoms that you’ve been experiencing. To diagnose the condition, we’ll measure the shape of your cornea. Computerized Corneal Topography is used for this procedure, which takes a picture of your cornea and analyzes it instantly.

Treatment for Keratoconus

The first line of treatment is usually new prescription eyeglasses. If this solution doesn’t help you achieve good vision, then contact lenses will be tried. Rigid, gas permeable lenses are typically prescribed.

As the disease progresses, however, glasses and soft contact lenses may no longer correct vision and soft lenses may become uncomfortable. This is when other forms of vision correction will be recommended.

Gas Permeable and Scleral Contact Lenses

At the more advanced stage of keratoconus rigid gas permeable (RGP) contact lenses, scleral or semi-scleral lenses may be used for increased comfort and visual acuity. Since they are more rigid, RGP and scleral lenses are able to create a smooth, round shape around the cornea, creating a smoother surface for better vision.

Scleral or semi-scleral lenses have a larger diameter which covers the entire cornea and reaches over into the white part of the eye, which is known as the sclera.

Many patients find these more comfortable than regular RGPs and find that they move around less when the eyes move. The main disadvantage of these rigid lenses is that for some, they are somewhat less comfortable than soft lenses and they must be continually refitted as the shape of the eye changes.

Whether it is glasses or contact lenses being used to correct vision, patients will likely have to undergo many tests and prescription changes as their vision needs to change.


Intacs are small, surgically implanted plastic inserts which are placed on the cornea to flatten it back to shape. Usually they are able to restore clear vision, with the continued use of glasses. Intacs are often recommended when contact lenses and eyeglasses are no longer able to correct vision adequately. Intacs take about 10 minutes to insert and can delay the need for corneal transplant.

PTK for severe keratoconus

Severe keratoconus may lead to extreme scarring, due to overstretched collagen fibers. If the back of your corneas tears as a result, swelling may occur. It can take months for the swelling to go down, and a large scar is generally created. PTK, a specialized procedure, can smooth out this scar, thereby enhancing contact lens comfort.

Cornea collagen crosslinking

Cornea collagen crosslinking is another therapy that has shown to be effective in slowing the progression of keratoconus. An alternate remedy is called intacs, which are semicircular implants inserted under the surface of the cornea to flatten the bulging cone shape and give better vision.

Cornea Transplant

As a last resort, a cornea transplant may be performed. During this procedure, the center of your cornea will be removed and replaced with a donor cornea. The new cornea is stitched into place, and you’ll need to wear contact lenses for adequate vision after the surgery.

Dangers of LASIK and Keratoconus

LASIK can potentially weaken the cornea of anyone who suffers from keratoconus, making it a dangerous procedure. If this happens, your vision will become substantially worse. Even if your keratoconus is mild, LASIK is not an option.

Our Keratoconus Specialist in New Holland, Pennsylvania is happy to meet with you for a 1-on-1 consultation to get you back on the path to reaching clear vision.
