Keratoconus Diagnosis
To test for keratoconus, your AEP eye doctor will check for distorted vision, blurred vision of objects (both near and far), sudden changes in one eye's vision or double vision when using only one eye and halos around bright lights.

Keratoconus can be diagnosed by examination and history. Our doctor's review the patient's complete medical and ocular history. A comprehensive ocular examination will be performed including refraction, slit lamp examination, pachymetry, and corneal topography. A slit-lamp is a kind of low-power microscope that shines a bright beam of light into the eye that is used to evaluate subtle changes to the corneal structure that can indicate keratoconus and evaluate the degree of corneal compromise from the disease.
Corneal topography is performed using the latest technology in a Topograhy System which is a state of the art computerized instrumentation to create a map of the cornea. This is advanced technology and offers the most complete view of your cornea. Using the Pathfinder Corneal Analysis and Master Fit II Contact Lens software, our doctors can diagnose, classify, and properly fit the most complex cases of keratoconus.

If you are considering corrective laser eye surgery, it is imperative you do not even have borderline keratoconus. Corneal topography will be performed on any patient seeking LASIK treatment to make sure they do not have keratoconus before scheduling surgery.
Advanced Treatment of Keratoconus

Contact Lenses
Advanced Eye Care Professionals. P.C., offers the latest technology in keratoconus management. Keratoconus can be corrected over a lifetime using rigid gas-permeable contact lenses, hybrid contact lenses, or scleral lens large diameter contact lenses. The doctors at AEP strive to offer the best in contact lens technology including but not limited to:

• Rose K/ Rose K2 gas permeable lenses
• SynergEyes KC and UltraHealth hybrid technology
• Blanchard's Mini-Scleral Design ( MSD)
• Boston AKC gas permeable lenses
• Alden Optical Zenlens

Surgical Options

INTACS for Keratoconus
Intrastromal corneal ring segments: a surgical procedure where small implants are inserted into the eye to correct vision. Collagen Cross Linking with Riboflavin (C3-R)/CXL. New research indicates that keratoconus may be treated with a procedure called Corneal Collagen Cross-linking with Riboflavin (C3-R® or CXL). Corneal cross-linking is a method where custom riboflavin eye drops are activated by ultra-violet light over a 30-minute session, which aids in increasing collagen cross-linking in the cornea and thereby strengthen the cornea and stabilizing ectasia. Chicago Cornea Consultants was one of the first sites to participate in the investigational study of CXL and Dr. Hogan has co-managed with Chicago Cornea Consultants since 1997.

Corneal Transplant & Post-graft Contact Lenses
In advanced cases of keratoconus, corneal transplant surgery may become necessary. Less than ten percent of patients reach the point where contact lenses are no longer the best option and a form of corneal transplant surgery will be recommended.

Our doctors work with the best corneal transplant surgeons in the Chicago area who are on staff at Christ Hospital, University of Chicago, Loyola University Hospitals, and Rush University Medical Center. Contact lenses may be necessary after corneal transplant surgery for optimal visual correction.

Dr. Hogan specializes in fitting post-graft contact lenses and receives referrals from Chicago area corneal specialists regularly who trust her expertise with the care of their patients.
