Abstract Details


Intraocular multifocal lens implantation is probably the best solution in patients undergoing cataract extraction and wishing to become independent to glasses. However, halo may be a concern in some patients. Furthermore, age related diseases like glaucoma, epimacular membrane or age related macular degeneration may develop and significantly decrease image quality. Therefore, easy removal of the multifocal intraocular lens could be interesting in these cases. We report our first experience with the sulcus multifocal diffractive 1stQ Add-On lens, during classical phakoemulsification.


Fondation A de Rothschild and Bichat Hospital, Paris, France.


3 patients (4 eyes) underwent cataract extraction by phakoemulsification with monofocal aspherical in the bag lens implantation. In the same time, a multifocal diffractive 1stQ Add-On lens was implanted in the sulcus. Uncorrected visual acuity (UCDVA), best corrected distance visual acuity (BCDVA), and uncorrected near visual acuity (UCNVA), were evaluated at one and 3 months postoperatively. Lens stability was also assessed.


UCDVA was 20/30 in all eyes, BCDVA was 20/25 or better, and UCNVA was20/30 or better. Spherical equivalent was within ±0,50D in all eyes at 1 month and 3 months post operatively. 2 patients reported halo at night. The Add-On lens was stable at 3 months. No pigment nor membrane developed between the lenses.


Sulcus implantation with the multifocal Add-On lens during classical phakoemulsification is an interesting option when considering multifocal implantation. The reversibility of this technique is a major advantage. FINANCIAL INTEREST: NONE
