Abstract
Purpose :
To report outcomes of patients with keratoconus fitted with soft contact lenses who have a history of failing rigid contact lenses.
Methods :
A retrospective chart review of 48 eyes of 29 patients with keratoconus, who previously failed with corneal rigid gas permeable lenses, scleral lenses, hybrid lenses, or piggyback system lenses, and then were successfully fit with soft contact lenses from 2017 to 2020. Principal outcomes measured were the number of remakes, indications for remakes, and reasons for failure.
Results :
Of the 48 eyes that were attempted to be fit with a soft contact lens, 14 eyes failed, yielding a 70.8% overall success rate. 6 eyes were lost to follow-up, 4 eyes failed due to unacceptable or unstable vision, 1 eye due to inadequate comfort, 1 due to health complications, and 2 eyes failed due to a combination of poor comfort and inadequate vision. The average number of soft lenses needed to finalize a fit was 1.64 ± 0.81. Of lens remakes, 5.8% were for fit modifications, 0% for material changes, 64.7% for optics, and 29.4% for a combination of changes. For patients who achieved a successful fit, the first fit success rate was 69.2%, and all fits were completed with 3 lenses or less.
Conclusions :
For patients with keratoconus who have previously failed rigid contact lenses, soft contact lenses may be a viable alternative.
