BACKGROUND: To compare the outcomes of sutured transscleral fixation and sutureless intrascleral fixation for the treatment of a dislocated intraocular lens (IOL).
METHODS: Thirty-five eyes of 35 patients who required IOL repositioning surgery due to IOL dislocation were included in this retrospective study. Sixteen eyes underwent two-point sutured transscleral fixation, eight eyes underwent one-point sutured transscleral fixation, and 11 eyes underwent sutureless intrascleral IOL fixation. The patients were followed for ≥ 12 months after repositioning surgery, and their postoperative outcomes were recorded and analyzed.
RESULTS: The major cause of IOL dislocation was ocular blunt trauma (19/35, 54.3%). The mean corrected distance visual acuity (CDVA) improved significantly after IOL repositioning (P = 0.022). The mean postoperative change in endothelial cell density (ECD) was - 4.5%. There were no significant differences in the changes in CDVA or ECD among the three groups with different repositioning techniques (both P > 0.1). The mean vertical tilt of the IOLs in all enrolled patients was significantly greater than the horizontal value (P = 0.001). The vertical tilt was greater in the two-point scleral fixation group than that in the sutureless intrascleral fixation group (P = 0.048). The mean decentration values in the one-point scleral fixation group in the horizontal and vertical directions were greater than those in the other two groups (all P < 0.01).
CONCLUSION: All three IOL repositioning techniques resulted in favorable ocular prognosis.
