OBJECTIVE: To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses (IOLs).
METHODS: This study retrospectively enrolled a consecutive series of patients who underwent a surgery of sutured existing subluxated or dislocated IOLs from October 2018 to June 2020. All patients underwent comprehensive preoperative and postoperative ophthalmologic examination, and data were collected including age, sex, surgical indications, best-corrected visual acuity, refractive error, intraocular pressure. Presence of intraoperative and postoperative surgical complications was documented.
RESULTS: A total of 20 consecutive cases were enrolled for analysis with mean final follow-up period 9.8±5.3mo. Visual acuity improved from a mean of 0.35 (0.46±0.32 logMAR) preoperatively to 0.61 (0.21±0.18 logMAR) at the 3-month follow-up (P=0.002). The mean amount of preoperative keratometric astigmatism and total postoperative refractive astigmatism was -1.24±0.80 diopters (D) and -1.42±0.97 D, respectively. There was no statistically significant difference between preoperative and postoperative astigmatism (P=0.156). The mean IOL-induced astigmatism was -0.23±0.53 D. The mean spherical equivalent at the 3-month follow-up was -0.1±0.94 D. No major complications were noted during the follow-up period.
CONCLUSIONS: Surgical techniques using sutured scleral fixation of existing subluxated or dislocated acrylic one-piece IOLs result in favorable visual and refractive outcomes without major complications.

UNASSIGNED: To present the outcomes of a new technique for intrascleral fixation of a flanged three-piece foldable intraocular lens (IOL) without a conjunctival incision.
UNASSIGNED: We retrospectively reviewed a consecutive series of 12 eyes of 12 patients who underwent scleral IOL fixation using this technique.
UNASSIGNED: The follow-up period ranged 3-12 months. There was a significant improvement in best-corrected visual acuity, from 0.8 (1.6) logarithm of the minimum angle of resolution (logMAR) preoperatively to 0.45 (0.8) logMAR at the final postoperative follow-up (p = 0.012). Notable complications included one case of pupillary IOL capture and increased intraocular pressure.
UNASSIGNED: Our novel technique is a viable solution for managing secondary IOL fixation, enabling the use of a wider variety of IOLs and simplifying the reposition process for dislocated three-piece IOLs. This approach has the potential to lower complication rates and enhance patients\' recovery.

BACKGROUND: Here we described a new threading technique for the universal fixation of any posterior chamber intraocular lens (IOL).
METHODS: Twenty-seven eyes of 27 patients whose surgery done by Surgeon A with the needle-guided method or the suture needle retrograde threading (SNRT) method for intrascleral IOL fixation were enrolled in the first group. Thirty-four eyes of 34 patients whose surgery done by Surgeon A, Surgeon B or Surgeon C with the SNRT method for intrascleral IOL fixation were grouped into three sub-groups by surgeon. Information regarding age, sex, best-available visual acuity (BCVA), intraocular pressure (IOP), past ophthalmological history, threading time (from puncturing to externalizing suture) and complications during and after the surgery were gathered.
RESULTS: The analysis showed that the threading time was less in the SNRT group than needle-guided group by Surgeon A. There was one eye with suture needle slipping from the guide needle when guiding out of the eye. The threading procedure was completed one time without suture ruptures or loop slippage in the SNRT group operated by Surgeon A. And using the SNRT method, Surgeon A, Surgeon B, and Surgeon C did not show any significant difference in threading time. No complications (e.g., vitreous hemorrhage, hyphemia, retinal detachment, suprachoroidal hemorrhage, or hypotony) were observed during surgery or postoperatively in all cases. No leakage occurred at the site of the puncture after the operation.
CONCLUSIONS: The described technique appears to be a safe, simple, easy-to-learn, and universal surgical method, which is suitable for various types of IOLs.

UNASSIGNED: This study aimed to present the 1-year follow-up of a modified technique for scleral fixation of three-piece intraocular lens (IOLs) without conjunctival incision.
UNASSIGNED: A retrospective chart review of a consecutive series of 10 eyes of nine patients who underwent scleral IOL fixation using the modified technique was performed. Data were collected 1 year after surgery for all patients.
UNASSIGNED: The range of follow-up time was between 1 year and 31 months. At the last follow-up point, the IOL was well-positioned and the visual acuity was good (as limited by primary diseases). Short-term complications included pupillary IOL capture (n = 1) and decreased intraocular pressure (n = 1), and no long-term complications were observed.
UNASSIGNED: Outcome data support this technique as a viable option for the management of secondary IOL fixation with flexible usage of more designs of IOLs.

BACKGROUND: This study aimed to report the visual acuity outcomes and complications of sutured scleral fixation of posterior chamber intraocular lens (IOL) in children under 9 years old with congenital ectopia lentis.
METHODS: Twenty-six children (47 eyes) with congenital ectopia lentis were included in this study. The mean age at surgery was 61.6 ± 22.3 months (range, 32-94). Patients underwent lens extraction, anterior vitrectomy, and sutured scleral fixation of posterior chamber IOL. The implanted IOL included rigid polymethyl methacrylate (PMMA) IOL (CZ70BD, n = 36) and foldable IOL (SA60AT, n = 9, and LI61SE, n = 2). The outcome measures used to assess the benefits were uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), refraction, intraocular pressure, and any associated complications. Median follow-up was 33.0 months (range, 4-129).
RESULTS: After surgery, the median UCVA (1.30 vs. 0.35 logMAR) and BCVA (0.82 vs. 0.15 logMAR) improved significantly (p < 0.001). The median absolute spherical values decreased considerably (9.00 vs. 0.75 D; p < 0.001). The median astigmatism was lower in foldable IOL compared to rigid PMMA IOL (1.0 vs. 2.5 D; p = 0.026), but neither the UCVA nor BCVA was significantly different. There was no intraoperative complication. Postoperative complications included pupillary capture in 4 eyes (9%), IOL decentration in 4 eyes (9%), choroid edema in 1 eye (2%), and subretinal hemorrhage in 1 eye (2%). The rate of secondary surgery was 9%, caused by IOL decentration of IOL haptics which was broken in 3 eyes and suture degradation in 1 eye.
CONCLUSIONS: Sutured scleral fixation of posterior chamber IOL provided good visual outcomes in children under 9 years of age with congenital ectopia lentis. Although there were some risks of secondary surgery, the complications were acceptable.

OBJECTIVE: To report the outcomes of anterior vitrectomy using high speed cutter for scleral fixated intraocular lens (SFIOL) implantation in patients with posterior capsular rupture.
METHODS: Medical records of 51 patients with posterior capsular rupture who received high speed cutter anterior vitrectomy via limbal incision with SFIOL implantation from June 2011 to December 2013 were reviewed retrospectively for visual outcomes and complications.
RESULTS: Totally 51 eyes of 51 patients were identified (23 males and 28 females). Mean age at surgery was 67.2±15y (range 27-91y), with mean follow-up of 23±8.2mo (range 12-40mo). The 49 (96.1%) eyes had improvement or unchanged of final postoperative visual acuity. The most common complication was vitreous haemorrhage (5.9%) and transient rise in intraocular pressure (5.9%) which all spontaneously resolved.
CONCLUSIONS: High speed cutter anterior vitrectomy via limbal incision is a safe and effective method for those with posterior capsular rupture for SFIOL implantation.

OBJECTIVE: To evaluate the efficacy of toric intraocular lens markers-assisted implantation of the scleral-fixated intraocular lens (SFIOL).
METHODS: From October 2010 to December 2013, all patients who had undergone secondary SFIOL implantation were assigned to group 1 and 2, in group 1 SFIOL was performed with the assist of radial keratotomy (RK)-marker, and in group 2 SFIOL was performed with the assisted of toric intraocular lens markers (T-and axis markers). Patients\' demographic data and information on baseline preoperative visual acuity, indication for surgery and latest postoperative visual acuity were collected and analyzed. The haptic and optic positions were determined by ultrasound biomicroscopy. The optic tilt angle and decentration distance were measured.
RESULTS: The study evaluated 43 eyes of 43 patients ranging in age from 3 to 66y. Group 1 comprised 24 eyes (24 patients) and group 2, 19 eyes (19 patients). Uncorrected reoperative acuity was improved on all the eyes postoperatively. The improved postoperative acuity was significantly more in group 2 than that in group 1 (1.11±0.38 vs 0.82±0.45 logMAR; F=4.85, P=0.03). Ultrasonic biomicrograph examination showed that the rate of haptic asymmetry was significantly higher in group 1 (42%, 10/24) than that in group 2 (11%; 2/19) (Chi square=3.68, P=0.04). The mean tilted degree in group 1 was significantly higher than that in group 2 (P=0.04). Mean decentration distance in group 1 was greater than that in group 2 (P=0.03).
CONCLUSIONS: During SFIOL the toric markers help the surgeon identify the placement of fixation more precisely than that with the use of RK marker.

The study was to report a new two-point scleral-fixation technique for foldable intraocular lenses with four haptics. Lenses were slid into the anterior chamber from a 2.8 mm corneal incision and fixed under two sclera flaps at two opposite points. The postoperative best-corrected visual acuities (BCVAs) of all patients were significantly better than their preoperative BCVA. The results demonstrate that two-point, scleral fixations of foldable, intraocular lenses might be practicable and effective.
