Abstract
IntroductionWe report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism.Case presentationA 53-year-old woman had undergone toric implantable collamer lens implantation three years earlier. After informed consent was obtained, we performed simultaneous toric implantable collamer lens removal and phacoemulsification with toric intraocular lens implantation. Preoperatively, the manifest refraction was 0, -0.5 × 15, with an uncorrected visual acuity of 0.7 and a best spectacle-corrected visual acuity of 0.8. Postoperatively, the manifest refraction was improved to 0, -0.5 × 180, with an uncorrected visual acuity of 1.2 and a best spectacle-corrected visual acuity of 1.5. No vision-threatening complications were observed.ConclusionToric intraocular lens implantation may be a good surgical option for the correction of spherical and cylindrical errors in eyes with implantable collamer lens-induced cataract and astigmatism.

We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism.Case presentation: A 53-year-old woman had undergone toric implantable collamer lens implantation three years earlier
The Visian Implantable Collamer Lens (Visian implantable collamer lens (ICL), STAAR Surgical, Nidau, Switzerland), a posterior chamber phakic intraocular lens (IOL), has been reported for superiority in postoperative visual performance compared to laser in situ keratomileusis and for safety and effectiveness in the correction of moderate to high ametropia [1,2,3]
Toric ICL removal and non-toric IOL implantation may lead to an increase in astigmatism in toric ICL-implanted eyes, because these eyes have some corneal astigmatism, and this astigmatism remains after these combined procedures
Summary
The Visian Implantable Collamer Lens (Visian ICL, STAAR Surgical, Nidau, Switzerland), a posterior chamber phakic intraocular lens (IOL), has been reported for superiority in postoperative visual performance compared to laser in situ keratomileusis and for safety and effectiveness in the correction of moderate to high ametropia [1,2,3]. We present here a case report indicating that simultaneous toric ICL removal and phacoemulsification with toric IOL implantation was beneficial for acquiring a good visual outcome in an eye with an ICL-induced cataract and astigmatism. No vision-threatening complications occurred, including rotation of the IOL, and the manifest refraction and her visual acuity remained stable throughout the six-month follow-up period
