BARCELONA — Using excimer laser vision correction to treat patients with residual refractive error after presbyopic IOL implantation reduces astigmatism and increases visual results, according to a presentation here.

David R. Hardten

"Our results are quite promising for these patients that wanted presbyopic correction. This is not uncommon, and presbyopic IOL results certainly improve with laser vision correction," David R. Hardten, MD, said at the European Society of Cataract and Refractive Surgeons meeting.

Fifty-nine eyes with residual refractive error after presbyopic IOL placement underwent excimer laser vision correction with PRK or LASIK. Thirteen eyes received a ReSTOR IOL (Alcon), 33 received a Crystalens (Bausch & Lomb), 12 eyes received a ReZoom IOL (Abbott Medical Optics), and one eye received a Tecnis multifocal IOL (AMO). Follow-up was at least 3 months (mean 12.2 months).

Overall, mean astigmatism decreased from 1.33 D preop to 0.41 ± 0.42 D at the last postop follow-up. Spherical equivalent decreased from 0.98 ± 0.81 D preop to an average –0.18 ± 0.52 D postop. Dr. Hardten said no eyes had a loss of more than one line of best corrected visual acuity, which was thought to be dryness.
