Dual optic accommodating lens
With distance correction, 23 eyes (96%) had an acuity of 20/40 or better at near.
Defocus curve analysis suggested a mean accommodative range of 3.22 diopters (D) ± 0.88 (SD) (range 1.00 to 5.00 D) in the accommodating IOL group and 1.65 ± 0.58 D in the control group (range 1.00 to 2.50 D) (Supported in part by unrestricted grants from That Man May See, San Francisco, California, and Research to Prevent Blindness, New York, New York, USA.

Vargas and Mc Leod have a financial interest in Visiogen Inc., and in the intraocular lens described.
All eyes had best corrected distance visual acuity of 20/40 or better, and 19 eyes (79%) had an uncorrected distance visual acuity of 20/40 or better.
Uncorrected near visual acuity was 20/40 or better in all eyes.
Conclusion: A dual optic intraocular lens design can increase the optical effect of a given displacement and suggests improvements for accommodating intraocular lenses.Patients were examined 1, 3, 6, and 12 months after surgery.
