Efficacy and safety of intraocular folding sutureless scleral fixating lens versus iris-claw intraocular lens implantation

Purpose. - To compare the refractive outcomes of sutureless scleral-fixated Carlevale (R) intraocular lenses versus Artisan (R) iris-claw-fixated tenses in terms of surgically induced astigmatism. Setting. - We included patients from the Quinze-Vingts National Ophthalmology Hospital, Paris, from August 2020 to December 2020. Design. - This was a single-center retrospective study. Methods. - Each patient included had undergone surgery with a sutureless scleral-fixated Carlevale (R) foldable intraocular lens or an Artisan (R) iris-claw lens in the context of secondary implantation. Exclusion criteria included a history of retinal detachment or any other retinal disease. We analyzed postoperative refractive data three months after surgery for the Carlevale group and three months after removal of all sutures for the Artisan group. Results. - A total of 25 eyes of 25 patients were included in the Carlevale group and 37 eyes of 36 patients in the Artisan group. At three months, the best-corrected visual acuity was not statistically different, at 0.33(+/- 0.35) and 0.32(+/- 0.33) LogMAR, respectively (P= 0.99), and surgically induced astigmatism was significantly lower in the Carlevale group, at 0.538 (+/- 0.560) and 2.30 (+/- 3.97) Diopters, respectively (P<0.001). Conclusions. - In this first comparative study, Carlevale (R) intraocular lenses appear to offer better refractive accuracy and less induced astigmatism than Artisan (R) iris-claw lenses, without increasing mean surgical time.
