Abstract:

Background: Toric Implantable Collamer Lenses (TICLs) are increasingly being used by doctors and patients due to their good safety, stability, and effectiveness. However, there is still a problem with rotation. A large degree of rotation results in the recurrence of astigmatism and decreased visual acuity. Rotation can be treated with relocation; however, rotation may recur. Case Report: A 26-year-old man presented to our clinic complaining of decreased visual acuity in his left eye. He had undergone TICL implantation in his left eye, and experienced spontaneous TICL rotation five times and underwent relocation five times to correct it at another clinic. The Uncorrected Visual Acuity (UDVA) was 20/100, the manifest refraction (MR) was +2.0D -3.0D × 150°, and the TICL was rotated 52°. In our clinic, he underwent TICL explantation, followed by implantation of a Spherical ICL (SICL) combined with astigmatic keratotomies, requiring 4.1 mm and 2.8 mm incisions. Three months postoperatively, the UDVA was 20/18, and the MR was -0.25D -0.25D × 170°. Conclusion: The combined implantation of an SICL with astigmatic keratotomy after TICL explantation is a safe effective treatment for recurrent astigmatism due to TICL rotation.
