Purpose: To examine the current causes of intraocular lens (IOL) explantation, compare various IOL explantation techniques, and assess the visual outcomes and complications.
Design: Retrospective comparative case series.
Participants: A total of 175 eyes of 160 patients who underwent IOL exchange for a one-piece foldable acrylic IOL between January 2010 and March 2022 were covered by the research. Group 1 included 74 eyes from 69 patients in which the IOL was removed after being grasped, pulled, and refolded inside the main incision. Group 2 consisted of 66 eyes from 60 patients in which the IOL was removed by bisecting it, whereas group 3 included 35 eyes from 31 patients in which the IOL was removed by enlarging the main incision.
Main outcomes: Surgical indications, interventions, visual outcomes and refraction, and complications.
Results: The mean patient age was 66.1 ± 10.5 years. The mean time between primary surgery and IOL explantation was 57.0 ± 38.9 months. IOL dislocation (in 85 eyes, 49.5%) was the most common reason for IOL explantation. When the patients were examined in terms of both surgical indication groups and IOL removal techniques, corrected-distance visual acuity increased significantly in all subgroups (P < .001). The increase in astigmatism after surgery was 0.08 ± 0.13 diopters (D) in group 1, 0.09 ± 0.17 D in group 2, and 0.83 ± 0.29 D in group 3 (P < .001).
Conclusions: The grasp, pull, and refold technique for IOL explantation provides a simpler surgery, less complication, and good visual outcomes.
