Abstract
To compare the long-term outcomes of sutureless intrascleral fixation of the intraocular lens (IOL) versus sutured scleral fixation. We retrospectively analyzed the medical records of patients who underwent intrascleral fixation of the intraocular lens using two different techniques: trocar-cannula-based sutureless fixation and sutured scleral fixation. Clinical outcomes were compared before and 1-, 3-, 6-, and 12-month follow-ups after the operation. 51 patients were followed over a 12-month period after the operation, including 28 eyes in the sutureless group and 23 eyes in the sutured group. Best-corrected visual acuity and spherical equivalent values reached targeted values faster in the sutureless scleral fixation of the intraocular lens. However, no significant difference was observed between the two groups. For IOL capture, there was a statistically significant difference observed in the incidence of postoperative complications, which was demonstrated by one eye in the sutureless group and seven in the sutured group (p=0.009). To exclude the effect of corneal astigmatism, surgically induced astigmatism (SIA) was calculated based on the astigmatism value one year after surgery. It was found that the sutureless technique significantly reduced the occurrence of astigmatism (2.43 ± 1.42 vs 1.65 ± 0.94, p=0.031). In a one-year follow-up period, the trocar-cannula-based sutureless technique was reliable and effective. Sutureless fixation was associated with fewer postoperative complications and lower SIA values than those with sutured fixation.
