Minimally Invasive and Advanced Treatment for Keratoconus

Dr. Laurence T.D. Sperber is a board-certified ophthalmic surgeon providing treatment for keratoconus and many other optical disorders at his practice in New York, NY. Keratoconus, also known as KC, is a condition that causes the cornea to bulge outward in a cone-like projection and negatively affect your vision. Although the exact cause of keratoconus is unknown, the disorder is very common in the United States with one in every 2,000 Americans affected by the abnormality. Dr. Sperber can provide several treatment options depending on your unique concerns to help you enjoy your vision once again.

What is Keratoconus?

While a normal, healthy cornea is round in shape, keratoconus causes your cornea to become thin and protrude in a cone-like bulge. This change in shape can affect the way that your eye perceives incoming light, resulting in vision impairment that can make simple tasks like driving, reading, and work life very problematic. Although the exact cause of keratoconus is still unknown, genetic disposition, eye rubbing, and allergies have been linked to its occurrence.

Signs and Symptoms 

Although there are no serious side effects associated with early keratoconus, both the early and advanced symptoms of the disorder can be extremely uncomfortable and affect your ability to participate in everyday activities. 

Early Signs 

In the early stages of keratoconus, you may experience blurry or distorted vision. Lines that previously appeared straight may look wavy. Sensitivity to light is also common, and you may experience redness. You should refrain from rubbing your eyes, as this can worsen the condition. 

Advanced Symptoms 

As keratoconus progresses, it can cause your vision to become even more blurred and distorted. If you previously wore contact lenses to correct nearsightedness or astigmatism, you may find that your contact lenses no longer fit comfortably. Advanced keratoconus can cause superficial scarring on the surface of the cornea, which can lead to decreased vision and increased discomfort.

Diagnosing Your Condition 

During your eye exam, Dr. Sperber will assess the health and curvature of your cornea using digital mapping. He will identify whether any changes have occurred on the surface of your eye and base your recommended treatment on your unique condition. 

Dr. Sperber offers several treatment options tailored to your unique condition for the most effective results.

Treatments for Keratoconus

For mild cases of keratoconus, Dr. Sperber may recommend non-invasive treatment such as eyeglasses, while more advanced cases of KC may be more effectively treated with hard contact lenses. If these are ineffective at correcting your KC, Dr. Sperber may perform intact placement, corneal collagen cross-linking, or a corneal transplant. 


Intacs are curved devices that are placed in your cornea by Dr. Sperber to flatten the curve of your cornea and substantially improve your vision.They are a minimally invasive treatment option and can also help address myopia and astigmatism in patients with keratoconus. Although these are highly effective at correcting keratoconus, your vision will usually return to its abnormal state once the intacs are removed. 

Corneal Collagen Cross-Linking 

Another minimally invasive treatment option offered by Dr. Sperber is corneal collagen cross-linking. During the procedure, Dr. Sperber will apply riboflavin drops and ultraviolet (UV) light therapy to strengthen your cornea and help it become flatter. 

Corneal Transplant 

If your cornea is irreversibly damaged and unresponsive to traditional, minimally invasive treatments, your best treatment option may be a corneal transplant. During this procedure, Dr. Sperber will replace parts or all of your damaged cornea with healthy donor corneal tissue.
