영문 초록

Purpose: To assess visual acuity, spherical aberration and contrast sensitivity in patients who were implanted with spheric, aspheric ReSTOR? or Crystalens HD? lenses. Methods: The present study enrolled 16 patients (32 eyes) implanted with biliateral spheric ReSTOR? (four patients, spheric ReSTOR group), bilateral aspheric ReSTOR? (seven patients, aspheric ReSTOR group) or bilateral Crystalens HD? (five patients, Crystalens HD group) lenses. At three months postoperatively, visual acuity, spherical aberration, and contrast sensitivity were evaluated. Results: Three months after surgery, there were no significant differences in uncorrected distant or intermediate visual acuity among the three groups. Uncorrected near visual acuity in the spheric and aspheric ReSTOR groups was superior to that in the Crystalens HD group, and the aspheric ReSTOR group had less spherical aberration. Mesopic contrast sensitivity in the Crystalens HD group was significantly higher at three cycles per degree compared to those in the spheric and aspheric ReSTOR groups. Conclusions: Uncorrected near visual acuity in the Crystalens HD group was inferior to those in the spheric and aspheric ReSTOR groups, but the mesopic contrast sensitivity of the Crystalens HD group at three cycles per degree was superior to those in the spheric and aspheric ReSTOR groups.
