Objective:
To evaluate the safety, efficacy, and on-eye performance of KeraSoft 3 contact lenses (UltraVision) in ectatic corneal diseases.
Methods:
The charts of patients who were fit with KeraSoft 3 were reviewed. The reason for KeraSoft 3 lens fit, the number of trial lenses required for ideal fit, centration, movement, and stabilization of the contact lens, uncorrected, spectacle-corrected, and contact lens-corrected visual acuities, slitlamp biomicroscopy findings, patient comfort, and daily duration of contact lens wear were evaluated.
Results:
Seventy eyes of 40 patients were fit with the KeraSoft 3 lens. Indications included rigid gas permeable (RGP) lens intolerance in 41 eyes of 24 patients (58.5%), patients' desire to use soft contact lenses in 26 eyes of 14 patients (37.1%), and proud nebula in 3 eyes of 2 patients (4.4%). The number of trial lenses required for ideal fit was 1.2±0.4 lenses. Eleven patients (20 eyes, 29%) never purchased the contact lens, 15 patients (26 eyes, 37%) discontinued after purchasing, and 14 patients (24 eyes, 34%) continued successfully wearing their lenses. In the latter group, the visual acuity improved significantly (P<0.05) and no adverse events were encountered during the mean follow-up period of 10.0±9.8 months. At the last follow-up examination, patients rated comfort and visual acuity with their contact lenses as "very good" to "excellent," with a desire to continue wearing them.
Conclusion:
In refractive correction of corneal ectasia, KeraSoft 3 contact lenses seem to be a good alternative to RGP lenses before more sophisticated lenses such as hybrid or scleral lenses are tried.
