Abstract

Purpose
The purpose of this study was to evaluate the effect of axial length and anterior chamber depth in vitrectomy and intraocular lens intrascleral fixation with a fibrin adhesive.
Methods
The study retrospectively reviewed 61 eyes of 61 patients, who were followed up for over 6 months after surgery. The patients were divided into three groups according to their axial length: group 1, < 22 mm; group 2, 22 to < 25 mm; and group 3, > 25 mm. The patients were further divided into three sub-groups according to their anterior chamber depth: group A, < 3.0 mm; group B, 3.0 mm to < 3.6 mm; and group C, > 3.6 mm. We measured and analyzed the best-corrected visual acuity, spherical value, cylindrical value, and spherical equivalent of each group before surgery and at 6 months postoperatively.
Results
When comparing the groups preoperatively and postoperatively, the best-corrected visual acuity, spherical value, and spherical equivalent showed significant improvement in all groups (p < 0.05). The incidence of complications, such as haptic slippage and intraocular lens dislocation, increased with the axial length and anterior chamber depth.
Conclusions
The use of fibrin adhesive for intraocular lens intrascleral fixation improves visual acuity and reduces refractive error. Postoperatively, there was no significant change in cylindrical value. Because axial length and anterior chamber depth affect refractive error, both should be considered in correlation with the surgical method.
