Abstract

Purpose
We evaluated the difference in clinical outcome according to the use of double-needle stabilizer in flanged intrascleral fixation of intraocular lens (IOL). Method: We retrospectively analyzed the medical records of 44 patients (44 eyes) who underwent flanged intrascleral fixation of IOL. Groups 1 and 2 (respectively) underwent surgery that did not and did employ a double-needle stabilizer. We evaluated the best-corrected visual acuity (BCVA), intraocular pressure, spherical equivalent (SE), refractive prediction error (RPE), IOL tilt and decentration, and other complications.
Results
The postoperative BCVA, SE, and RPE did not differ between the two groups (p = 0.672, p = 0.131, p = 0.247). IOL tilt was significantly less in group 2 than in group 1 (p = 0.038, p = 0.015 [horizontal and vertical]) (3.96 ± 2.01° horizontally and 4.17 ± 2.07° vertically in group 1; 2.59 ± 2.02° horizontally and 2.50 ± 1.92° vertically in group 2). IOL decentration was also significantly less in group 2 than in group 1 (p = 0.001, p = 0.004 [horizontal and vertical]) (0.44 ± 0.21 mm horizontally and 0.45 ± 0.20 mm vertically in group 1; 0.25 ± 0.09 mm horizontally and 0.27 ± 0.13 mm vertically in group 2).
Conclusions
Use of a double-needle stabilizer during flanged intrascleral fixation of IOL significantly reduced postoperative IOL tilt and decentration, and may thus improve postoperative visual quality.
