Many patients with keratoconus can achieve clear vision by wearing standard, rigid gas-permeable (RGP) contact lenses. However, when standard contact lenses fail to correct eyesight sufficiently, specialty lenses may be an effective solution. At the thriving optometry practice of Clarity Eye Care, in Lombard, IL, keratoconus patients with weak vision have benefitted from being fit expertly with customized contact lenses. In addition to successfully providing sharp vision for individuals with keratoconus, Dr. Matthew Hendrickson is highly qualified and experienced in fitting specialty lenses for patients with poor post-surgical corneas, due to LASIK or RK.
Detailed and comprehensive measurements of the cornea must be taken in order to fit specialty lenses perfectly. To this end, a thorough eye exam is performed in the Lombard office, located near Villa Park, IL. The most critical part of this eye exam is the process of mapping each patient’s corneas. Using advanced optometric technology, including optical coherence tomography (OCT) and fluorescein bio microscopy, the accurate fit of the lenses is determined. Adjustments are generally required, and the power and fit may need tweaking until the ideal, comfortable lens is identified.
Keratoconus describes an ocular disorder in which corneal thinning occurs. This leads to an irregular corneal surface that is also cone-shaped, and visual images are distorted as light passes through the cornea. Typical symptoms include blurred vision and frequent changes in eyeglass prescriptions. Patients with these symptoms are often interested in refractive surgery for vision correction, and screening for keratoconus is an important part of their preoperative evaluation. “Many people who are considering LASIK come for an eye exam in our Lombard clinic, and we often diagnose keratoconus during these assessments. It’s always difficult to inform patients that they’re not candidates for surgery due to this corneal problem,” says Dr. Hendrickson.
Fortunately, specialty contact lenses offer an effective method to correct vision with keratoconus. Dr. Hendrickson recalls one of his early patients who presented with extremely distorted corneas due to multiple incisions from RK surgery. With 20/70 vision, she had been told that she would never be able to wear contacts with success. However, using scleral lenses, he transformed her eyesight to 20/20 in one eye and 20/40 in the other eye. This is a classic example of how patients with keratoconus disease, post-surgical eyes or irregular corneas will be amazed by their new, sharp vision after a professional custom contact lens fitting in Lombard, IL.
