SynergEyes lenses for keratoconus

Cornea. 2010 Jan;29(1):5-8. doi: 10.1097/ICO.0b013e3181a9d090.

Abstract

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. The mean age was 40 +/- 12.6 years; the mean follow-up period was 7.8 +/- 4.6 months. The most common indication for SynergEyes was rigid gas permeable (RGP) lens intolerance, 31 of 61 eyes (50.8%). Inability to fit with RGP was the indication in 8 eyes (13.1%), and 22 eyes (36%) were refit from SoftPerm (Ciba Vision, Corp, Duluth, GA). Twenty-two patients required refitting, including 17 base curve changes and 5 skirt changes. The success rate was 86.9% (53 of 61 eyes). Most failures (8 eyes of 6 patients) discontinued the lens within the first 1-2 months because of discomfort (5 eyes) or unsatisfactory vision (3 eyes).

Conclusion: SynergEyes lenses are a promising alternative for visual rehabilitation in patients with KC and PMD who are intolerant or unable to be fit in RGP lenses.
