Simplified Technique for Correcting Intraocular Lens Decentration in Scleral-Sutured Fixation Surgery

To describe a simplified technique for correcting intraocular lens (IOL) decentration during scleral-sutured IOL fixation surgery.

During surgery, Purkinje images were utilized to assess IOL positioning. A straightforward IOL decentration adjustment technique was employed when necessary. Patients in whom IOL position were corrected and who were followed up for at least three months after surgery were included in the study.

From June 2023 to February 2024, six patients with noticeable IOL decentration were successfully treated using this technique. After a mean follow-up of 3.17 ± 0.37 months, there was a significant change in spherical equivalent (preoperative +10.55 ± 2.48 D, postoperative -1.58 ± 2.19 D). While the best-corrected visual acuity, refractive cylinder, intraocular pressure, and corneal endothelium density remained unchanged. Importantly, the IOL was well-centered in all six patients, with average horizontal and vertical IOL decentration of 0.21 ± 0.16 mm and 0.20 ± 0.15 mm, respectively.

This simple IOL decentration correction technique demonstrated favorable results and may enhance IOL positioning in scleral fixation procedures.
