To evaluate the safety and efficacy of a dual-optic accommodating intraocular lens


LV Prasad Eye Institute, Hyderabad, India


A prospective nonrandomized, noncomparative interventional case series in which 24 eyes with uncomplicated senile cataract were enrolled to undergo phacoemulsification and placement of the Bausch and Lomb accommodating intraocular lens. Patients were examined at 1st, 7th post-operative day and one, three, six and twelve months post-operatively. Subjective evaluation of accommodation was done by defocus curves and objective methods used to test accommodation included visual acuity with and without spectacle addition, pentacam evaluation and ultrasound biomicroscopy. Primary outcome measures included post-operative uncorrected and best corrected distance and near visual acuities and accommodative range based on amplitude of accommodation.


Twenty-one eyes of 24 patients completed the study. At the end of one year, all patients had best corrected distance visual acuity of 20/40 or better and 14 eyes (66.66%, 95% CI 43.11% to 84.52%) had uncorrected visual acuity of 20/40 or better. The mean minimum add required to reach 0.40 logMAR (N6/J2) or better was 1.75 D ± 0.58 D at one month, 1.78 ± 0.64 D at 3 months, and 2.08 ± 0.66 D at one year. The mean amplitude of accommodation at 3 D was 0.11 D, 0.24 D, and 0 D at one month, 3 months, and one year respectively.


While the dual-optic IOL had uncorrected and best-corrected distance visual acuity and safety comparable to standard monofocal IOL; there was no significant accommodation provided by this IOL FINANCIAL DISCLOSURE?: No
