Refractive lens exchange with Acri.LISA bifocal intraocular lens implantation.

PURPOSE: To assess efficacy, safety, and predictability after refractive lens exchange (RLE) in patients who had bilateral implantation of an Acri.LISA 366D diffractive bifocal intraocular lens (IOL).

METHODS

Sixty-six eyes of 33 consecutive patients were examined after RLE who had bilateral implantation of an Acri.LISA bifocal 366D IOL. Eyes were divided into myopic and hyperopic groups. Monocular uncorrected distance visual acuity, best-corrected distance visual acuity (BCVA), uncorrected distance near visual acuity, and best distance-corrected near visual acuity (BCNVA) were recorded preoperatively and 6 months after surgery.

RESULTS

Efficacy indexes were 0.73 for myopic and 0.85 for hyperopic eyes at 6 months postoperatively. For the myopic group, 2 eyes lost 1 line, 4 eyes gained 1 line, and 6 eyes gained ≥2 lines; for the hyperopic group, 11 eyes lost 1 line, 8 eyes gained 1 line, and 7 eyes gained 2 lines. Safety indexes were 1.07 and 1.03 for myopic and hyperopic eyes, respectively. Safety indexes at near were 1.03 for myopic and 1.00 for hyperopic eyes. Efficacy indexes at near were 1.00 for myopic and 0.99 for hyperopic eyes.

CONCLUSIONS

Bilateral implantation of an Acri.LISA 366D bifocal IOL after RLE is an effective procedure for correcting ametropia and presbyopia.
