Abstract
Purpose: To compare postoperative vision, high-order aberrations, contrast sensitivity, power of accommodation, and depth of focus of monofocal aspheric (TECNIS ZA9003) and multifocal aspheric (TECNIS ZM900) intraocular lenses (IOL). Methods: Thirty-four eyes which received intraocular lens implantation in the posterior chamber were equally divided into two groups: TECNIS ZA9003 (17 eyes) and TECNIS ZM900 (17 eyes). Before and three months after surgery, visual acuities at near, intermediate, and far distances, and depth of focus were recorded. High order aberrations, spherical aberrations and accommodation power were measured with iTrace, and contrast sensitivity was evaluated using Optec 6500. An independent T-test analysis was used to compare the two groups. Results: There were no significant differences of high order aberrations, spherical aberrations, accommodation power, or distance vision between the two groups at three months postoperatively. The multifocal IOL (TECNIS ZM900) group revealed better intermediate and near vision (p<0.01) and deeper depth of focus, and lower contrast sensitivities (p=0.03) than the monofocal IOL group. Conclusions: There was no difference in accommodation power between the two groups, but multifocal TECNIS ZM900 IOL exceeds monofocal TECNIS ZA9003 IOL in intermediate and near vision due to diffractive lens design and less spherical aberration by its asphericity
