How is Keratoconus Diagnosed?

The initial symptoms of keratoconus include frequent and significant changes in a patient’s eyeglass prescription, especially in the amount of astigmatism. This is often followed by progressive vision problems such as halos, glare symptoms, ghost images, double and multiple images perceived by each eye individually, and by numerous attempts at obtaining a good glasses prescription without success.

Early diagnosis is very important in the management of keratoconus. New advanced technologies allow eye doctors to detect and treat the condition very successfully.

Non-surgical Treatment Options for Keratoconus

Treatment strategies for the management of keratoconus are expanding as new technologies are being developed. The choice of what treatment to consider is based on the severity of the disease. As stated previously, early or mild cases of keratoconus can be easily treated with traditional eye glasses. Many of these patients can achieve clear 20/20 vision with spectacles. New spectacle technologies that correct for what are termed “high order aberrations” that are common in keratoconus may play a role for slightly more advanced cases.

Surgical Treatment Options for Keratoconus

Medical and surgical options for the treatment of keratoconus are also expanding and improving. Corneal transplantation (penetrating keratoplasty or “PK”) has been utilized for the surgical management of keratoconus for many decades. The criteria for PK surgery typically is either the development of corneal scaring that reduces best corrected vision (even with contact lenses) or intolerance to contact lens wear (due to poor comfort or the inability to achieve a stable fit). Modification and improvement in surgical techniques has made PK much more successful.

Cassidy’s Story – a Sharing Vision Grant Program Recipient

Cassidy is one of the first recipients of the Sharing Vision Grant program, a program designed to provide the new hybrid contact lenses ClearKone® to patients who may otherwise not have access to this new contact lens technology.  Her story is below.

The History of Hybrid Lens Technology

Patient excitement for a contact lens is created when the first lens placed on the eye provides good vision and feels great.  Success in contact lens wear depends upon the patient achieving their vision, comfort and eye health goals. At one time patients could only choose between rigid gas permeable lenses (RGPs) and soft lenses so patients often had to compromise on either vision or comfort. Today there is another technology option available called the hybrid contact lens.

Research Study – A Comparison of SynergEyes KC Lens versus Traditional RGP Lens Designs for Patients with Irregular Cornea

ABSTRACT

Objectives. To compare whether patients with irregular corneas are more comfortable wearing SynergEyes®, a hybrid contact lens, compared with rigid gas permeable contact lenses.

Methods. A retrospective chart review of patients seen from the specialty contact lens practice at the University of Pittsburgh, who were refit with hybrid lenses from November 2005 to December 2006. Inclusion criteria included presence of irregular astigmatism in at least one eye from any cause,

Clinical Research Study – SynergEyes KC Lenses

Purpose: To discuss the initial results of fitting SynergEyes hybrid contact lenses (SynergEyes, Inc, Carlsbad, CA) for keratoconus (KC) and pellucid marginal degeneration (PMD).

Methods: The charts of patients fit with SynergEyes lenses during the first 7 months the lens was available on the Cornea Service at Wills Eye Institute (August 3, 2006 to March 5, 2007) were retrospectively reviewed.

Results: Sixty-one eyes (44 patients) with KC (58 eyes) or PMD (3 eyes) were fit with SynergEyes hybrid contacts.
