“…In previous studies about sutured scleral fixation, the complication rates of IOL capture were reported up to 30%. 13,14 The other studies assessing alternative sutured scleral fixation methods using Gore-Tex have reported complication rates of IOL tilt up to 45%. [15][16][17] However, most studies have reported good centration of IOL and pupillary capture was resolved spontaneously.…”

Purpose: To compare the long-term outcomes of sutureless intrascleral fixation of the intraocular lens versus sutured scleral fixation.Methods: The authors retrospectively analyzed the medical records of patients who underwent intrascleral fixation of the intraocular lens using two different techniques: trocarcannula-based sutureless fixation and sutured scleral fixation. Clinical outcomes were compared before and 1-, 3-, 6-, and 12-month follow-ups after the operation.Results: A total of 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 intraocular lens 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 was calculated based on the astigmatism value 1 year after surgery. It was found that the sutureless technique significantly reduced the occurrence of astigmatism (2.43 6 1.42 vs. 1.65 6 0.94, P = 0.031). Conclusion:In a 1-year follow-up period, the trocar-cannula-based sutureless technique was reliable and effective. Sutureless fixation was associated with fewer postoperative complications and lower surgically induced astigmatism values than those with sutured fixation.

“…In this study, no recurrence of pupillary optic capture occurred after IOL repositioning with postoperative pilocarpine 2.0%. Kim et al 22 reported that peripheral iridotomy helped to prevent pupillary capture after conventional sutured scleral fixation. However, in this study, peripheral iridotomy sites were constructed in all cases, and they did not completely prevent pupillary optic capture.…”

Purpose: To identify risk factors for pupillary optic capture after sutureless flanged intraocular lens (IOL) fixation for IOL dislocation.Methods: This retrospective comparative study enrolled consecutive patients who underwent flanged IOL fixation using 25-gauge pars plana vitrectomy. One hundred twenty-six eyes (126 patients) were divided into two groups according to the presence or absence of pupillary optic capture. A swept-source anterior segment optical coherence tomography and a rotating Scheimpflug camera were used to analyze and compare surgical parameters, including axial length, anterior chamber depth, differences in scleral tunnel angle and length, and IOL tilt and decentration, between the two groups.Results: Compared with the nonpupillary optic capture group (106 eyes, 84.1%), the pupillary optic capture group (20 eyes, 15.9%) had larger differences in the nasal and temporal scleral tunnel angles and larger horizontal tilt (P , 0.05). Multivariate regression analysis demonstrated that these factors correlated with the occurrence of pupillary optic capture (P , 0.05).Conclusion: To prevent pupillary optic capture after flanged IOL fixation, surgeons should avoid asymmetry in the angles of the nasal and temporal scleral tunnels, which causes horizontal IOL tilt and subsequent pupillary capture.
