Background

The aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (posterior chamber intraocular lenses) and to demonstrate a method for validating the lens position.

Methods

Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated posterior chamber intraocular lenses using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center.

Results

<10% decentration

the intraocular lens was only slightly off-center from the line of sight

More results

All patients had ocular comorbidities, mainly glaucoma (n = 6) and pseudoexfoliation syndrome (n = 5).

Best corrected visual acuity improved from a median of 6/30 (0.7 logMAR) to a median of 6/12 (0.35 logMAR) (p = 0.06); postoperative astigmatism measured 0.91 ± 2.19 diopters.

More results

Ultrasound biomicroscopy demonstrated well-balanced posterior chamber intraocular lenses fixation with no difference between the horizontal and vertical tilt measurements (p = 0.84; p = 0.94; p = 0.62; p = 0.085).

There was a high negative correlation between BCVA improvement and residual lens tilt (r = -0.76, p = 0.037).

Conclusion · 1 of 2

Subluxated posterior chamber intraocular lenses are amenable to treatment with minimally invasive fixation using Gore-Tex suture with good anatomic outcomes.

Conclusion · 2 of 2

ultrasound biomicroscopy image analysis may serve as a valuable method for assessing posterior chamber intraocular lenses position following scleral fixation.
