Abstract
BACKGROUND Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015 to December 2020. METHODS Patient historical factors, intraoperative/postoperative complications, and outcomes of IOL type (anterior chamber IOL versus scleral sutured IOL versus scleral fixated IOL versus. sulcus) were assessed. Primary outcomes were rates of postoperative retinal tears and rhegmatogenous retinal detachment. Secondary outcomes were rates of intraoperative endolaser, intraoperative retinal tear, and further IOL surgery. RESULTS The incidence of intraoperative retinal tears was 7.3% and not significantly different between techniques. Rates of intraoperative endolaser use were 17.5% among all techniques and not significantly different between techniques. Rates of postoperative retinal tear were low (0%-2.7%). Rates of postoperative rhegmatogenous retinal detachment were not significantly different between techniques (anterior chamber IOL 9/198 [4.5%], SFIOL 1/54 [1.9%], scleral sutured IOL 14/274 [5.1%], sulcus 2/35 [5.7%], total 26/561 [4.6%], P = 0.79). Rates of repeat IOL surgery trended higher in sulcus lenses (anterior chamber IOL 5/198 [2.5%], SFIOL 4/54 [7.4%], scleral sutured IOL 16/274 [5.8%], sulcus 5/35 [14.3%], total 30/561 [5.3%], P = 0.12). CONCLUSION Intraoperative endolaser use and intraoperative retinal tear are not uncommon in secondary IOL surgery and underscore the importance of careful vitreoretinal management among these patients.

[PMID: 38771460 PMCID: PMC11178701 DOI: 10.1007/s40123-024-00962-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 04/30/2024] [Indexed: 05/22/2024] Open
Abstract
INTRODUCTION The purpose of our study was to compare the safety and efficacy of two scleral fixation intraocular lens (IOL) methods of four-point scleral fixation (Akreos AO60) and the Yamane technique (AcrySof MA60AC). METHODS This prospective, randomized study was conducted at the Military Institute of Medicine-National Research Institute in Warsaw between 2021 and 2023. We compared both groups for cause of aphakia, ocular history, refractive status, and complication. RESULTS Our study included 50 eyes from 47 patients. Four-point fixation was performed in 25 eyes (group 1), and the Yamane technique was used in 25 eyes (group 2). Surgical time was 24.1 min ± 8.9 in group 1 and 25.1 min ± 9.9 in group 2 (p > 0.05). The postoperative BCVA (best-corrected visual acuity) for group 1 and group 2 at 1 year's observation was 0.10 ± 0.15 and 0.09 ± 0.17 logMAR, respectively (p > 0.05). Postoperative total refractive error (RE) was - 0.06 ± 0.71 diopters (D) for four-point scleral fixation and 0.83 ± 0.70 D for Yamane technique (p < 0.05). Endothelial cell density (ECD) loss was 0.9% in group 1 and 3.5% in group 2 (p > 0.05). Bleeding into the anterior chamber and vitreous body was more frequent in the group of patients operated on with the use of the Yamane technique (10 cases, 20%, p = 0.01). IOL displacement was found in one case (2%) in group 2. CONCLUSIONS Both analyzed techniques are well tolerated and ensure good refractive results (extremely predictable in four-point scleral fixation) and have a similar safety profile. Four-point scleral fixation of IOL would appear to be safe, effective and beneficial for young, active patients, especially after trauma or recurrent subluxation. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov identifier NCT06389643.

Abstract
PURPOSE To describe a unique case of Gore-Tex (Gore Medical, AZ) suture-associated delayed-onset endophthalmitis in a patient with a history of scleromalacia, pathologic myopia, multiple prior vitrectomies in the setting of a scleral-sutured intraocular lens (IOL). METHODS A 69-year-old man complained of blurry vision and eye pain 21 months after implantation of a scleral-sutured IOL and was found to have an exposed Gore-Tex suture with scleromalacia, vision loss to hand motion, a hypopyon, and vitritis. He was diagnosed with culture-positive endophthalmitis. He had a previous history of a rhegmatogenous retinal detachment repair and subsequent dislocated IOL in this eye treated with a scleral-sutured IOL. A vitreous tap and injection of broad-spectrum antibiotics and suture removal at the slit lamp were performed at the time of presentation. One week later, he underwent pars plana vitrectomy and removal of the IOL. RESULTS After the tap and inject and subsequent lens removal, his vision has returned to his preoperative vision of 20/100 with refraction. DISCUSSION Gore-Tex suture is a nonabsorbable and flexible option with great tensile strength that has emerged as a favored alternative to polypropylene for the use in transscleral fixated IOLs. Although endophthalmitis and suture erosion are known complications of this procedure, this report describes one of the first cases of Gore-Tex suture-associated endophthalmitis.

Abstract
PURPOSE To describe long-term visual and anatomical outcomes of sutured scleral-fixated intraocular lens (SF IOL) implantation. SETTING Tertiary eyecare hospital in India. DESIGN Retrospective interventional noncomparative study. METHODS Postoperative change in corrected distance visual acuity (CDVA) and occurrence of complications were assessed from the patient medical records. Long-term SF IOL survival rates and factors affecting the occurrence of postoperative IOL-related complications were assessed. Patients with postoperative follow-up less than 10 years or incomplete medical records were excluded. RESULTS 64 eyes of 53 patients were included. Follow-up duration was 11.4 ± 1.2 years. Mean preoperative CDVA was 0.71 ± 0.43 logMAR (Snellen equivalent: 6/30), and mean CDVA at the final visit was 0.52 ± 0.49 logMAR (Snellen equivalent: 6/18) (P < .01). 48% cases had CDVA of 6/12 or better at the last follow-up. 58% cases had coexistent ocular pathology affecting the final visual outcome. IOL and suture-related complications were the commonest and included IOL decentration (17% cases), IOL drop (14%), and suture exposure (6%). The probability of IOL survival (postoperative period without IOL-related complications) was 90.6% at 8 years and 81.2% at 10 years (Kaplan-Meier analysis). Occurrence of postoperative IOL-related complications was unaffected by patient sex, age, indication for surgery (trauma or other), previous intraocular surgery, or technique of scleral fixation (2-point or 4-point) (multivariate regression analysis). CONCLUSIONS Although sutured SF IOL implantation is viable with favorable long-term visual outcomes, there is a risk of postoperative IOL-related complications. Occurrence of postoperative IOL-related complications is unaffected by patient and ocular factors.

Abstract
INTRODUCTION To describe a novel surgical approach in the management of subluxated cataracts. METHODS A 70-year-old Caucasian male with a subluxated cataract in the left eye was referred to our clinic at the Azienda Ospedaliero-Universitaria di Bologna- Ophthalmology Unit. The ophthalmic examination revealed a best-corrected visual acuity (BCVA) of 20/200 in the left eye with monocular diplopia and a severely subluxated NO6/NC6 cataract and the fundus examination did not reveal any vitreoretinal abnormalities. The right eye had 20/20 BCVA and was pseudophakic. After a 300° conjunctival peritomy, a single 25-gauge valved trocar 4 mm was inserted from the limbus in the inferotemporal quadrant, where the cataract was mainly dislocated and a corneal paracentesis to reduce the anterior chamber intraocular pressure was performed. Subsequently cohesive viscoelastic was progressively injected in the retrolental space through the trocar, to recenter and elevate the subluxated cataract. Thereafter, a complete centered capsulorhexis was performed, four capsular hooks were inserted to stabilize the bag, and complete phacoemulsification was performed with intact posterior capsular support. In the end, given the lack of capsular support elements such as the Cionni ring or Ahmed segment, a sutureless scleral fixated intraocular lens was implanted. RESULTS One week after surgery, the BCVA was 20/25, and the final BCVA at 6 months was 20/20, without any complications. CONCLUSIONS Retrolental cohesive ophthalmic viscoelastic injection could represent a novel effective surgical approach in recentering and elevating subluxated cataracts, facilitating the capsulorhexis, and reducing the risk of a pars plana approach.

Abstract
Purpose To present a modified technique of 4-point scleral fixation using polymethyl methacrylate (PMMA) 2 eyelets intraocular lens (IOL) with 8-0 polypropylene sutures. Methods A 270-degree conjunctival peritomy is done, and 4 sclerotomies (2 nasal and 2 temporal) are created. Lamellar scleral or clear corneal incision is made at superior site (6 mm wide for sclera or 5.5-6 mm for corneal). A short segment of 8-0 polypropylene is inserted into each eyelet, each thread of the suture is externalized through the sclerotomy site, and the lens is inserted. The suture is tightened evenly, and the knot is rotated and internalized. Scleral incision and conjunctival peritomy are sutured with 8-0 vicryl. Results We have performed this technique in 6 patients with excellent visual outcomes and no reported complications over 1 year of follow-up. This technique has practical advantages including rigid and stable PMMA IOL, high tensile, and slim 8-0 polypropylene suture which is easily internalized and less irritated, and affordable and widely available overall consumables. Conclusion We present a modified 4-point scleral fixation technique for posterior chamber IOL placement using PMMA IOL with 2 eyelets and 8-0 polypropylene as compared to previous studies that used foldable IOL with 4 eyelets and 10-0 polypropylene or Gore-Tex sutures. This procedure has moderate technical complexity, comparable to previously reported techniques with good overall clinical outcomes and several practical advantages, particularly related to the affordability and availability of the consumables.

Abstract
OBJECTIVE To identify changes in secondary lens techniques over time and to determine common complications of each technique. DESIGN Retrospective cohort study. PARTICIPANTS All patients in the database from January 2015 to December 2021 who underwent secondary lens placement (anterior chamber intraocular lens [IOL, ACIOL], scleral-fixated IOL [SFIOL], or scleral-sutured IOL [SSIOL]). METHODS Rates of secondary IOL surgery techniques were analyzed in 3597 participants in a nationwide aggregated electronic health care database using 2-sample independent t tests. Rates of postoperative rhegmatogenous retinal detachment (RRD) after secondary IOL surgery were assessed using chi-square test of proportion. Postoperative visual acuity (VA) was assessed using 2-sample independent t tests. MAIN OUTCOME MEASURES The primary outcome was change in IOL technique over time. Secondary data points examined were the development of postoperative RRD after secondary IOL surgery, VA changes, the development of endophthalmitis, suture erosion, haptic erosion, or corneal edema after IOL surgery. RESULTS Anterior chamber IOL use decreased over the 7-year period from 93% of cases to 36% of cases (P < 0.0001), while SFIOL use increased from 3% to 34% (P < 0.0001) and SSIOL use increased from 4% to 30% (P < 0.0001). Visual acuity increased for each surgical technique (ACIOL: 44.1 vs. 49.2 ETDRS letters, P < 0.001; SFIOL: 48.7 vs. 57.6 letters, P < 0.001; SSIOL: 51.5 vs. 61.2 letters, P < 0.001), with larger VA gains seen in SFIOL and SSIOL use (ACIOL vs. SFIOL, P = 0.004; ACIOL vs. SSIOL, P = 0.002; SFIOL vs. SSIOL, P = 0.64). Average RRD rates did not significantly differ between techniques. Rates of endophthalmitis, haptic erosion, and suture erosion were low and did not significantly differ between techniques. Rates of corneal edema were significantly higher in ACIOL cases (vs. SFIOL, P < 0.0001; vs. SSIOL, P < 0.0001). CONCLUSIONS Rates of ACIOL implantation performed by vitreoretinal surgeons have decreased over time with more vitreoretinal surgeons electing to place either an SFIOL or SSIOL toward the end of the study period; complication profiles among the 3 techniques may be similar.

Abstract
Purpose 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. Materials and Methods 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. Results 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. Conclusion Outcome data support this technique as a viable option for the management of secondary IOL fixation with flexible usage of more designs of IOLs.

Abstract
An Intraocular Lens (IOL) fixated on the iris either anteriorly, as a phakic IOL, or posteriorly, as an aphakic IOL, can influence pupil motility. In this interventional case series study, we evaluated pupil size under different levels of illumination (scotopic = 0.04 lx, low-mesopic = 0.4 lx and high-mesopic = 4 lx) for anterior iris-claw IOL fixation for correcting myopia or hyperopia (IFPH), retropupillary iris-claw IOL fixation to correct aphakia or as treatment for late in-the-bag IOL dislocation/subluxation (IFRP), and capsular-fixation IOL in-the-bag implantation (IB). Pupil size was measured preoperatively for the IFPH- and IB-group as well as 6 months after surgery for all groups. We analyzed a total of 70 eyes: 22 eyes of 11 patients with phakic IOLs, 22 eyes of 20 patients in the IFRP group and 26 eyes of 13 patients in the IB group. Both IFPH and IB showed a smaller postoperative scotopic pupil size, compared with the preoperative values. When compared to postoperative values of IB and IFPH, IFRP showed a significantly smaller postoperative scotopic pupil size (IFPH: 5.89 ± 0.83 mm, IFRP: 4.37 ± 0.83 mm, IB: 5.34 ± 0.98 mm, p < 0.001) while no differences were seen at high-mesopic lighting. Neither of the surgical techniques seems to impair the constriction of the pupil.

Abstract
PURPOSE To report a series of patients who developed neurotrophic keratopathy following scleral fixation of intraocular lenses. METHODS Retrospective case series of patients undergoing implantation of scleral fixated IOLs with various techniques. RESULTS Three patients developed NK in the immediate post-operative period following scleral fixation of IOLs. Scleral fixation of IOL was performed using three different techniques (4-point fixation, "Yamane" flanged intrascleral and tunneled intrascleral haptic fixation). None of the patient had any prior risk factors for the development of NK. In all patients, intrascleral haptics or scleral sutures were positioned on the horizontal meridian. All patients also underwent light peripheral retinal endolaser. CONCLUSIONS NK can rarely occur following scleral fixation of IOLs. The combination of suturing or intrascleral fixation of the IOL on the horizontal meridian and peripheral retinal endolaser may synergistically damage to the long ciliary nerves with a "two-hit" mechanism and cause NK.

Abstract
PURPOSE The aim of this article is to describe an innovative and minimally invasive surgical technique for posterior vitrectomy combined with secondary intraocular lens implantation, using a sutureless scleral fixation Carlevale intraocular lens (I71 FIL SSF Carlevale lens. Soleko IOL Division, Italy). METHODS The technique was conducted with only three transconjunctival sclerotomies and a corneal tunnel to perform intraocular lens explantation, posterior vitrectomy and Carlevale intraocular lens implantation. It is easier, quicker, and less invasive than the traditional technique with conjunctival peritomy, two scleral flaps and five sclerotomies. RESULTS Surgery was performed uneventfully on three eyes of three patients. Two of them presented a luxation of the intraocular lens into the vitreous chamber, while one patient presented an intraocular lens subluxation. No complications were observed after a 5 to 8 months of follow-up. The intraocular lenses were well positioned, no conjunctival erosion was noted, and the intraocular pressure remained normal at all stages. CONCLUSIONS This is the first report of a combined procedure of IOL explantation, posterior vitrectomy and secondary IOL implantation using only three transconjunctival sclerotomies. This appears to be less invasive and it causes less discomfort to the patient. We suggest considering this technique in all those cases requiring a combined procedure in absence of a proper capsular support.

Abstract
PURPOSE Flanged intrascleral haptic fixation (FISHF) is a useful method for securing intraocular lenses (IOLs) in eyes without capsular support. Biomechanical studies were conducted to support the use of this technique. DESIGN Laboratory investigation. METHODS Haptics of 3-piece IOLs were passed through cadaveric human sclera using 30- and 27-gauge needles. Flanges were created by melting 1.0 mm from the haptic ends using cautery. The forces required to remove the flanged haptic from the sclera and disinsert the haptic from the optic were measured using a mechanical tester and a custom-fabricated mount. RESULTS The mean FISHF dislocation force using 30-gauge needles was greatest with the CT Lucia 602 (2.04 ± 0.24 newtons [N]) compared to the LI61AO (0.93 ± 0.41 N; P = .001), ZA9003 (0.70 ± 0.34 N; P = <.001), and MA60AC (0.27 ± 0.19 N; P <.001). Using 27-gauge needles with the CT Lucia resulted in a lower dislocation force (0.56 ± 0.36 N; P <.001). The FISHF dislocation force was correlated with the flange-to-needle diameter ratio (r = 0.975). The FISHF dislocation forces of the CT Lucia and LI61AO using 30-gauge needles were not significantly different from their haptic-optic disinsertion forces (P = .79 and .27, respectively). There were no differences in flange diameters between 1.0 mm and 2.0 mm haptic melt lengths across the IOLs (P = .15-.85). CONCLUSIONS These data strongly support the biomechanical stability of FISHF with the polyvinylidene fluoride haptics of the CT Lucia using small diameter instruments for the creation of an intrascleral tunnel. 1.0 mm of haptic may be the optimal melt length.

Abstract
This review aimed to evaluate the cumulative incidence, patient characteristics, predisposing conditions, and treatment outcomes for late in-the-bag intraocular lens (IOL) dislocation. Literature searches in PubMed (MEDLINE), Embase, and Cochrane Library Central database identified 1 randomized clinical trial, 1 prospective case series, 2 prospective cohort studies, and 36 retrospective studies of this condition, which showed that the cumulative incidence was 0.5% to 3%, it occurred on average 6 to 12 years after cataract surgery, and mean patient age was 65 to 85 years. Pseudoexfoliation syndrome, myopia, and previous vitreoretinal surgery were the most common predisposing conditions. Studies indicated that IOL repositioning and IOL exchange provided similar visual outcomes and were equally safe. The long-term visual outcome seemed satisfactory. However, the quality of evidence regarding treatment was in general quite low. More studies of late in-the-bag IOL dislocation are needed, and in particular, different surgical techniques should be included in high-quality clinical trials.

Abstract
PURPOSE To evaluate surgical and refractive outcomes of a new sutured scleral fixation technique in the management of subluxated intraocular lenses (IOLs). METHODS Nineteen eyes treated with the new scleral fixation technique were included. The mean corrected distance visual acuity (CDVA), postoperative refraction error, mean endothelial cell count (ECC), and complications were recorded. All patients were evaluated immediately postoperatively, at 1 and 7 days, and then at 1, 3, and 6 months. RESULTS The mean duration of follow-up of the patients was 10 months (range, 6-15 months). The mean CDVA was 0.41 ± 0.1 logMAR (logarithm of minimum angle of resolution) preoperatively and was 0.08 ± 0.07 logMAR postoperatively. The mean astigmatism was - 2.22 ± 1.86 D preoperative and was - 0.86 ± 0.58 D postoperative. The mean preoperative and postoperative ECC was 2455 ± 288 and 2352 ± 288, respectively. One patient (5.26%) experienced vitreous hemorrhage, and two (10.52%) experienced intraocular pressure elevation. IOL tilt and decentralization, conjunctival erosion, and cystoid macular edema were not observed in any eyes during follow-up. CONCLUSION This new IOL repositioning technique can be applied in a short surgical time and provides a stable IOL centration on long-term follow-up.
