Purpose:
To evaluate the objective and subjective performance of the Holo-Or multifocal contact lens, a new rigid gas permeable (RGP) trifocal diffractive contact lens.
Methods:
Eleven experienced and two non-experienced RGP contact lens wearers participated in the study. Eleven patients were presbyopic (age range: 40-57 years) and two were aphakic (ages: 12 and 14 years). Each patient was evaluated by comparing best spectacle correction to Holo-Or multifocal contact lens correction, using the following tests of visual function: visual acuity at 6 m, 80 cm, and 40 cm; contrast sensitivity at near and distance; and depth of focus.
Results:
No significant differences were found between best spectacle correction and the Holo-Or contact lenses. When using the contact lenses, there was an improvement in depth of focus and a small reduction in contrast sensitivity compared with best spectacle correction. Overall satisfaction and comfort was good to excellent in ten of thirteen patients.
Conclusions:
Holo-Or trifocal diffractive contact lenses are a satisfactory means of optical correction for patients with presbyopia or accommodative problems.
