Comparison of Short-term Clinical Outcomes between Sutured Scleral Fixation and Modified Yamane Sutureless Scleral Fixation

Purpose: To compare and investigate the short-term clinical outcomes between 10-0 polypropylene sutured intraocular lens (IOL) scleral fixation and modified Yamane sutureless IOL scleral fixation in patients with IOL or crystalline les dislocation and aphakic state.Methods: From August 2012 to May 2022, medical records were retrospectively analyzed for 43 patients with sutured scleral fixation and 40 patients with sutureless scleral fixation. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), total astigmatism, IOL astigmatism, refractive error, corneal endothelial cell density, surgical time and complications were compared before surgery, 1 week, 1 month, and 3 months after surgery.Results: In the two groups, after 3 months of surgery, UCVA and BCVA improved compared to before surgery, but there was no significant difference between two groups. The absolute refractive error and total astigmatism for one week after surgery and IOL astigmatism for one week and one month after surgery were significantly lower in sutureless fixation group. There was no significant difference in postoperative corneal endothelial cell density changes between two groups, and total surgical time and IOL fixation time were measured significantly lower in sutureless fixation group.Conclusions: Although modified Yamane sutureless IOL scleral fixation did not show significant improvement in visual acuity compared with conventional sutured IOL scleral fixation, sutureless fixation provided better stability of IOL in the early stages after surgery and short in the surgical time. So it can be an effective alternative to conventional sutured scleral fixation in patients with IOL or crystalline lens dislocation and aphakic state.
