Jin, Seungbum, Sung, and Nam: Clinical Results of CrystalensⓇ (AT-45) Accommodating Intraocular Lens

Abstract

Purpose:

To evaluate one-year clinical results of Crystalens (AT-45, Eyeonics, CA, USA) accommodating IOL implantation.

Methods:

In this retrospective study, 25 eyes of 18 patients had phacoemulsification and Crystalens accommodating IOL implantation. Distance and near visual acuity (VA) during the 12-months were measured.

Results:

At two months, uncorrected distance visual acuity (VA) of 13 eyes (52.0%) and 21 eyes (84.0%) were 20/25 and 20/40 or better, respectively. At six months, 11 eyes (44.0%) and 21 eyes (84.0%) were 20/25 and 20/40 or better, respectively. At 12 months, 11 eyes (44.0%) and 17 eyes (68.0%) were 20/25 and 20/40 or better, respectively. At two months, the uncorrected near VAs of 11 eyes (44.0%) and 17 eyes (68.0%) were 20/25 and 20/40 or better, respectively. At six months, 9 eyes (36.0%) and 16 eyes (64.0%) were 20/25 and 20/40 or better, respectively. After 12 months, 6 eyes (24.0%) and 16 eyes (64.0%) were 20/25 and 20/40 or better, respectively.

Conclusions:

The uncorrected near VAs gradually decreased with the passage of time until 12 months after Crystalens accommodating IOL implantation.
