PURPOSE
To compare clinical outcomes of various surgical methods of intraocular lens dislocation correction surgery. METHODS: We retrospectively analyzed the medical records of patients who underwent intraocular lens dislocation correction surgery with and without vitrectomy by two seasoned surgeons, and compared postoperative best corrected visual acuity and spherical equivalent. Clinical outcomes of secondary intraocular lens insertion after primary intraocular lens removal and primary intraocular lens reposition were compared among the cases without vitrectomy. RESULTS: Dislocated intraocular lens correction without vitrectomy showed better postoperative visual acuity compared to procedures with vitrectomy (0.35 +/- 0.37 vs. 0.54 +/- 0.18; t-test, p = 0.001), but there were no significant differences in spherical equivalent (1.30 +/- 1.10 vs. 1.80 +/- 1.57; p = 0.24) between cases with and without vitrectomy. In comparing primary intraocular lens reposition and secondary intraocular lens insertion among the cases without vitrectomy, the outcomes did not show significant differences in best corrected visual acuity (0.28 +/- 0.40 vs. 0.40 +/- 0.37; p = 0.38) or spherical equivalent (1.66 +/- 1.43 vs. 1.07 +/- 0.79; p = 0.19). In comparing secondary intraocular lens insertion into the capsular bag and fixation to the sclera, iris and iris sulcus, the outcomes did not show significant differences in best corrected visual acuity (p = 0.49) or spherical equivalent (p = 0.33). CONCLUSIONS: The various intraocular lens correction methods examined did not show clinically significant differences in best corrected visual acuity and spherical equivalent when performed by experienced surgeons, except for better postoperative best corrected visual acuity in cases without vitrectomy compared to cases with vitrectomy. |
