Abstract

Abstract : Purpose : To determine whether differences in sclerotomy size during intrascleral intraocular lens (IOL) fixation influence IOL tilt and visual acuity after surgery. Setting : University of Fukui Hospital and Japanese Red Cross Fukui Hospital, Japan. Design : Retrospective case series. Methods : The study reviewed the records of patients who had intrascleral IOL fixation with transconjunctival 25‐gauge pars plana vitrectomy and a follow‐up longer than 6 months. The preoperative and postoperative visual outcomes, degree of IOL tilt, and intraoperative and postoperative complications were statistically compared between the sclerotomy groups. Results : The study included 65 eyes (60 patients). Postoperatively, the maximum degree of IOL tilt was significantly smaller in the 24‐gauge sclerotomy group than in the 30‐gauge sclerotomy group ( P = .003). The degree of IOL tilt was significantly correlated with the amount of postoperative IOL astigmatism (total astigmatism − corneal astigmatism) ( P = .0001, R 2 = 0.23). There were no statistically significant differences in the preoperative or postoperative corrected distance visual acuity (CDVA) or the complication rate between the sclerotomy groups. Conclusion : A smaller sclerotomy for intrascleral IOL fixation was associated with greater IOL tilt and IOL astigmatism after surgery; however, this did not clinically or significantly affect the postoperative CDVA.
