RATIONAL: The rationale of this study was to evaluate the visual and anatomical outcomes of pars plana lensectomy and iris-claw Artisan intraocular lens (IOL) implantation in patients with subluxated crystalline lenses secondary to Marfan syndrome. MATERIALS AND METHODS: In this retrospective case series, we evaluate the records of 21 eyes of 15 patients with Marfan syndrome and moderate-to-severe crystalline lens subluxation who underwent pars plana lensectomy/anterior vitrectomy and implantation of iris-claw Artisan IOL at referral hospital from September 2015 to October 2019. RESULTS: Twenty-one eyes of 15 patients (10 males and five females) with a mean age of 24.47 ± 19.14 years were included. Mean best-corrected visual acuity was improved from 1.17 ± 0.55 logMAR to 0.64 ± 0.71 logMAR at the final follow-up visit ( P < 0.001). The mean intraocular pressure did not change significantly ( P = 0.971). The final refraction showed a mean sphere of 0.54 ± 2.46 D and a mean cylinder of 0.81 ± 1.03 at the mean axis of 57.92 ± 58.33 degrees. One eye developed rhegmatogenous retinal detachment 2 months after surgery. CONCLUSIONS: Pars plana lensectomy and iris-claw Artisan IOL implantation seem to be a useful, impressive, and safe procedure with a low rate of complications in Marfan patients with moderate-to-severe crystalline lens subluxation. Visual acuity was significantly improved with acceptable anatomical and refractive outcomes.

Purpose: To evaluate the visual and anatomical outcomes of pars plana lensectomy and iris-claw artisan intra-ocular lens (IOL) implantation in the patients with subluxated crystalline lens secondary to Marfan syndrome.Methods: In this retrospective case series, we evaluate the records of all patients with Marfan syndrome and moderate to severe crystalline lens subluxation who underwent pars plana lensectomy/anterior vitrectomy and implantation of iris-claw artisan IOL at referral hospital from September 2015 to October 2019.Results: Twenty-one eyes of fifteen patients (10 males and 5 females) with the mean age of 24.47 ± 19.14 years were included. Mean best-corrected visual acuity was improved from 1.17 ± 0.55 logMAR to 0.64 ± 0.71 logMAR at the final follow-up visit (P <0.001). The mean intraocular pressure did not change significantly (P = 0.971). The final refraction showed a mean sphere of 0.54 ± 2.46 D and a mean cylinder -0.81 ± 1.03 at the mean axis of 57.92 ± 58.33 degrees. One eye developed rhegmatogenous retinal detachment two months after surgery.Conclusion: Pars plana lensectomy and iris-claw artisan IOL implantation seem to be a useful, impressive and safe procedure with a low rate of complications in Marfan patients with moderate to severe crystalline lens subluxation. Visual acuity was significantly improved with the acceptable anatomical and refractive outcomes.
