Abstract
Purpose To evaluate the short-term safety and efficacy of a novel approach of utilizing the 9-0 looped polypropylene suture with double knots buried into the scleral groove and the scleral tunnel to minimize the risk of the suture erosion and suture knot exposure. Design Clinical-based retrospective study. Methods Records of consecutive patients who had anterior vitrectomy and scleral-fixated posterior chamber intraocular lens (IOL) implantation between July 2018 and April 2020 with a minimum follow-up of 3 months were reviewed. Results This study enrolled a total of 21 eyes from 20 patients (15 male). These patients had a mean age of 58.52 ± 8.55 years and were followed for an average of 1.08 ± 0.58 years postoperatively. Best-corrected visual acuity (BCVA) improved from a preoperative mean of 0.43 ± 0.41 logMAR to a significantly higher mean 3-month postoperative value of 0.09 ± 0.21 logMAR (Z = -3.35, p < 0.01). There were no statistical differences between the preoperative and postoperative corneal endothelial cell density (p=0.71). The postoperative complications included transient increased intraocular pressure in 5 eyes (24%). No other complications were detected during the follow-up. Conclusions The modified technique proposed is a safe, effective, and reliable approach resulting in good visual outcomes. Our procedure might have the potential benefit to avoid suture-related complications in scleral-fixated IOL implantation. Trial registration. Retrospective case series study, not applicable.
Highlights
Efforts to prevent these complications have been employed including the rotating of suture knots into the eye, burying the suture ends into scleral tunnel, and covering suture ends with tenon’s capsule, scleral flaps, or pockets [8,9,10,11,12,13,14]. e key issues related to this process are the appropriate selection of suture materials and suture knotting approaches. e use of 10-0 polypropylene sutures is becoming increasingly unpopular because they degrade over time, eventually leading to the suture slippage and the subluxation and dislocation of the intraocular lens (IOL)
Many techniques of transscleral fixation of posterior chamber intraocular lens have been developed [17]. e focus is on preserving the integrity of the anterior chamber, reducing iridic contact and avoiding the damage of the ocular anatomy
Compared with anterior chamber IOL (AC IOL), retro-iris implantation is the main advantage of scleral-fixated PC IOL
Summary
Surgical outcomes of 21 eyes from 20 patients that underwent treatment using the 9-0 looped polypropylene suture to achieve IOL scleral fixation with double. Data from patients with a < 3-month postoperative follow-up or with incomplete operative or postoperative medical records were excluded from this study. Enrolled patients had complete records pertaining to their visual acuity (VA), slit-lamp photographs, and ultrasound biomicroscope (UBM) findings [15] During their initial baseline visit, each patient was subjected to comprehensive ophthalmic evaluations of best-corrected visual acuity (BCVA), as well as intraocular pressure, lens status, previous surgeries, preexisting ocular pathologies, and history of ocular trauma [15]. After the needle out at the radial scleral incision, the first ball-shaped knot was created in 3-2-1 fashion with the previous cut thread (Figure 1). The second thread knot was buried in the partialthickness sclera (Figure 1), and the suture was cut at the outlet of the scleral tunnel. All statistical analyses were performed using IBM SPSS Statistics Version 22
