To compare visual performance and functional tolerance of two multifocal diffractive intraocular lens, AcrySof ReSTOR SN60D3 (Alcon, Inc.) and Acri.LISA 376D (Carl Zeiss Meditec), two years after cataract surgery.
This monocentric, prospective, comparative study was conducted between March 2009 and September 2011. Inclusion criteria were patients between 50 and 80 years, no longer willing to wear glasses or contact lenses for distance and near vision, and wanting a cataract surgery with bilateral implantation. Cataract surgery was performed by the same surgeon using the same phacoemulsification technique . The parameters analyzed were biomicroscopic examination; monocular and binocular visual acuity with and without spectacle correction using ETDRS charts, at a distance of 4 meters for far vision, 66 centimeters for intermediate vision, 33 centimeters for near vision; monocular contrast sensitivity in photopic conditions ; glare sensitivity ; a quality of life questionnaire, assessing visual disturbances and dependence on glasses ; a macular OCT (Optical Coherence Tomography) analysis to exclude a maculopathy.
20 eyes (10 patients) received the ReSTOR intraocular lens (IOL) and 24 eyes (12 patients) received the Acri.LISA IOL in the Edouard Herriot Hospital, Lyon. There was no statistically significant difference (α=5%) between the two lens in terms of visual acuity for far and near vision, for monocular and binocular vision, for contrast sensitivity and glare test . There was a statistically significant difference in favor of Acri.LISA group for intermediate visual acuity specially for monocular uncorrected visual acuity (p = 0.03), binocular uncorrected visual acuity(p = 0.041) and binocular corrected visual acuity (p = 0.004) . The analysis of quality of life questionnaire did not find any statistically significant difference between the two groups and any correlation between visual discomfort during night driving and glare test.
This study shows that both IOL have similar visual performance (good level of satisfaction without eye glasses). Intermediate vision is better in the Acri. LISA group. It could be explained by the asphericity of the lens increasing the depth of field. This study (2 years of follow-up) confirms the results of previous studies reported in the literature (6 months and 1 year follow-up).
