Abstract Details

Purpose:

To assess visual performance of eyes treated with a small aperture IOL with a prior history of either a corneal inlay or laser refractive surgery.

Setting:

Prospective, single-site study.

Methods:

Nineteen cataract patients with a history of either corneal inlay implantation (Group 1, n=10) or laser refractive surgery (Group 2, n=9) were treated with contralateral implantation of an IC-8 IOL in one eye and a monofocal IOL in their fellow eye. Group 1 (N=10) received the IC-8 IOL in the eye previously treated with a corneal inlay. Prior to cataract surgery, the inlay was removed and patients were monitored for refractive stability. For both groups, the refractive target for IC-8 IOL eyes was -0.75 D and plano for the fellow monofocal IOL eyes.

Results:

Monocular UCVA of 20/25 or better was achieved by Group 1 in 86% for UDVA, 71% of UIVA and UNVA. In Group 2, monocular UCVA of 20/25 or better was in 63% or patients for UDVA, 75% for UIVA and 88% for UNVA. Binocularly, vision of 20/25 or better was achieved 100% for UDVA, 71% for UIVA, and 71% for UNVA by Group 1. Group 2 achieve 20/25 or better binocular vision in 67% for UDVA, 83% for UIVA and UNVA. Mean MRSE for the Group 1 was 0.14 D ± 0.66 and -0.70 D ± 0.43 for Group 2.

Conclusions:

Early results show the IC-8 IOL provides good distance, intermediate and near monocular uncorrected visual acuity for eyes with a history of inlay implantation or prior refractive surgery. Additional patients, data and follow-up to be captured out to 12 months post-op.
