To assess ocular and corneal aberrations in pseudophakic patients with customized-asphericity intraocular lens (IOL). To predict a residual ocular spherical aberration (SA) closed to 0 µm after a custom surgery.
10 patients received customized-aspheric IOLs in both eyes during a micro-incision cataract surgery. IOL asphericity was customized according to the pre-operative corneal SA measured with the Atlas 9000 ® (Carl Zeiss, Meditec USA). IOLs were selected according to their given SA either aspherical AcriSmart 36A (SA= -0,18 µ), or AcriSmart 46LC (SA = 0 µ) or spherical AcriSmart 46S (SA= +0,13 µ). 3-month postoperative evaluations were conducted including visual acuity, contrast sensitivities, pupil diameter, corneal and total aberrations.
Preliminary results of 10 eyes showed good post-operative results in term of total ocular residual SA : Corneal SA = 0,307 +/- 0,014 µ, Total SA = 0,028 +/- 0.014 µ with implantation of aspherical AcriSmart 36A. The mean value of high ocular aberrations root mean square was 0,158 µ. This optimization of ocular asphericity with customized IOL should be also evaluated for photopic and mesopic contrast sensitivities.
Bilateral implantation after micro-incision cataract surgery of a customized-asphericity IOL could reduce total spherical aberrations. The improvement of visual performances is in evaluation.
