[Comparison between OPD-Scan results and visual outcomes of Tecnis ZM900 and Restor SN60D3 diffractive multifocal intraocular lenses]. / Estudo comparativo do desempenho visual e análise de frente de onda entre as lentes intra-oculares multifocais difrativas Tecnis ZM900 e AcrySof ResTor SN60D3.

ABSTRACT

PURPOSE: Comparison of the visual performance and wavefront analysis between patients with Tecnis ZM900 aspheric and AcrySof ReStor SN60D3 spheric diffractive multifocal intraocular lenses (IOL). METHODS: This prospective comparative study included 78 eyes of 39 patients. The performed ophthalmologic evaluation included near, intermediate and distance corrected and uncorrected visual acuity, contrast sensitivity measurement (under photopic and mesopic conditions) and wavefront analysis with the OPD-Scan aberrometrer. RESULTS: Uncorrected near and distance visual acuity and aberrometry analysis were similar with both intraocular lenses; nevertheless, intermediate visual acuity and contrast sensitivity under photopic conditions were statistically better with Tecnis ZM900. CONCLUSION: Both studied intraocular lenses promoted excellent near and distance postoperative visual acuity, in high contrast situations. Tecnis ZM900 IOL provided good quality of vision with high contrast condition in low luminosity with reduction in spherical aberration and improvements in intermediate visual acuity when compared to Restor IOL.
