摘      要：Purpose:To evaluate postoperative astigmatism with regard to incision-induced astigmatism and deviation in axial alignment with the use of preoperative limbalmarking with the Javal keratometer(Haag Streit,Bern,Switzerland) in eyes implantedwith the Artisan toric phakic intraocular lens(IOL) (Ophtec,Groningen,The Netherlands) .Design:Prospective nonrandomized ***:Fifty-four eyes of 33 patients with myopia(mean,-9.67 diopters [D]) and astigmatism(mean,-3.44 D) .Intervention:The enclavation site was marked on the limbus using the Javal *** Artisan toric phakic IOL was implanted according to the axis marked on the *** was a minimum of 6 *** Outcome Measures:Safety index,efficacy index,predictability,safety,and vector analysis of total refractive correction were *** effects of axis misalignment and incision-induced astigmatism on the final refractive error were ***:At 6 months after surgery,the safety index was 1.29± 0.29 and the efficacy index was 1.04± *** spherical equivalent subjective refraction reduced from-11.39± 4.86 D before surgery to-0.38± 0.57 D at 6 ***-seven percent of eyes were within 0.50 D of attempted refraction and 89% were within 1.00 *** preoperative cylinder was 2.92± 1.60 D at 91.4°.At 6 months,the mean cylinder was 0.28± 0.54 D at 174.3°.No eyes lost 2 or more lines of best-corrected visual acuity at 6 ***-three percent of eyes achieved uncorrected visual acuity of 20/40 and 28% achieved 20/*** analysis of total surgically induced astigmatism revealed a mean cylindrical change of 3.21± 1.71 *** axis misalignment was 0.37± 5.34°.The mean incision-induced astigmatism was 0.74± 0.61 D at 0.2°.Conclusions:Implantation of the myopic toric IOL leads to safe,efficacious,and predictable *** level of unpredictability caused by minor axis IOL misalignment has minimal effects on the residual refractive *** procedure of axis alignment
