OBJECTIVE: To report the long term visual outcomes and complications with use of the novel CM-T Flex scleral fixated intraocular lens (CMT-SFIOL).
METHODS: 116 eyes that underwent CMT-SFIOL were reviewed and 57 eyes with CMT-SFIOL that completed a 2-year follow-up were included. Main outcome measures noted were best-corrected visual acuity (BCVA) and complications. Postoperatively, follow-ups were done at 1 week (1w), 1 month (1 m), 1 year (1y) and 2-year (2y) intervals.
RESULTS: 40 (70.17%) of 57 eyes received CMT-SFIOL for surgical aphakia. Mean follow up was 39.77 ± 8.44 months. BCVA for distance & near improved from 1.26 ± 0.84 to 0.76 ± 0.77, 0.50 ± 0.72 and 0.51 ± 0.73 & 1.28 ± 0.58 to 0.98 ± 0.49, 0.92 ± 0.44 and 0.89 ± 0.40 at 1 m, 1y and 2y respectively (p < 0.001 for all). At 1w, 10 eyes (17.54%) had corneal edema (CE) and 8 eyes (14.03%) had anterior chamber (AC) reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had vitreous hemorrhage (VH). At 1 m, 3 eyes (5.26%) had CE and 5 eyes (8.77%) had AC reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had VH. Cystoid macular edema was noted in 3 eyes (5.26%). At 1y and 2y, 2 eyes (3.5%) and 1 eye (1.75%), had CE. No decentration, dislocation, haptic exposure or retinal detachment was noted. No eyes required resurgery.
CONCLUSIONS: CM-T Flex SFIOL is an effective method to correct aphakia, with reliable and safe long-term results.

OBJECTIVE: This study aims to introduce a new suture method and report surgical outcomes of patients who underwent scleral-fixated intraocular lens (SF-IOL) implantation combined with either pars plana vitrectomy (PPV) or anterior vitrectomy (AV).
METHODS: Twenty-three eyes performed SF-IOL implantation combined with PPV (Group 1), and 34 eyes performed SF-IOL implantation combined with AV (Group 2) were included in the study prospectively. The SF-IOL, either polymethyl methacrylate or foldable IOL, was sutured into the sclera using PC-9 sutures in an irregular, knotless, and zigzag-shaped manner. The scleral tunnel was approximately 12-15 mm long, with at least four sharp edges. Suture tips were trimmed within the scleral tunnel. Postoperative outcomes and complications were evaluated.
RESULTS: Both groups showed no complications such as suture tip expulsion, suture reaction, IOL dislocation, or increased intraocular pressure during postoperative visits. Group 1 exhibited a statistically significant improvement in visual acuity compared to preoperative values (P = 0.036 for the 1st month, <0.001 for the 3rd month). Similarly, Group 2 demonstrated a statistically significant improvement in visual acuity compared to the preoperative period (P = 0.001 for the 1st month, <0.001 for the 3rd month).
CONCLUSIONS: The \"irregular, knotless, and zigzag-shaped scleral tunnel suture technique\" yielded favorable results in terms of IOL stability and visual acuity. This technique can be safely employed in patients undergoing SF-IOL implantation combined with PPV or AV.

UNASSIGNED: Surgical correction of aphakia without capsular support continues to be a challenge. Improvements in the technology of cataract surgery have provided advancements in techniques in surgical management of aphakia. Locally, we have limited data on the outcomes of the different intraocular lenses used in aphakia.
UNASSIGNED: This study aimed to determine visual outcomes and complications associated with different techniques of intraocular lens implantation in the absence of capsular support.
UNASSIGNED: We reviewed the medical charts of 207 patients who underwent intraocular lens implantation without capsular support. Excluded were patients with incomplete follow up, pediatric patients, and lost records. Best corrected visual acuity at day 1, 1st month, 3rd month and 6th month postoperatively, and the complications were noted.
UNASSIGNED: Mean age was 60 and 51% (n=105) were females. The mean follow-up time was 9.33 ± 0.71 months. Loss of capsular support was most frequently caused by intraoperative complication (n=146, 70%) and trauma. Retropupillary fixation iris claw intraocular lens was frequently used (n=93, 44.9%). Across all patients, visual acuities showed excellent outcomes with 20/50 or better. Across IOL types, the most frequent postoperative complication was increase in IOP. Statistically significant results were set at P <0.05.
UNASSIGNED: There is a notable preference towards iris claw retropupillary lenses through time. Iris claw lenses showed the shortest operative time. All intraocular lenses used in aphakia showed comparably good postoperative visual acuities, except for the superior visual acuity trend seen among retropupillary iris claw and anterior chamber IOL groups. Complications included elevated intraocular pressures, corneal edema, and pigment dispersion.

BACKGROUND: A novel technique is described employing scleral grooves to facilitate sutureless scleral fixation of the Carlevale intraocular lens (CIL). We describe its use in a series of 47 patients with aphakia.
METHODS: A retrospective study of all patients with aphakia who underwent CIL implantation with the new technique by a single surgeon during 1 year. The novelty of this technique consists in the creation of two partial-thickness linear sclerotomies (grooves), 180° apart, 2 mm from and parallel to the limbus. In the middle of each groove a full-thickness sclerotomy is performed to facilitate externalization of the CIL anchors. The groove allows the anchor to plug the full-thickness sclerotomy and to rest within the sclera without protrusion. Reported outcomes include pre-operative/post-operative visual acuity, post-operative spherical equivalent and surgical complications. Follow-up was a minimum of 6 months.
RESULTS: Forty-eight eyes of 47 patients with aphakia with a mean age of 74 years (range 31-90 years) are included. The commonest causes of aphakia were intraocular lens (IOL) subluxation,with or without exfoliation (54.2%), complicated cataract surgery (29.2%), crystalline lens luxation (6.3%) and trauma (4.1%). All CILs inserted with the new technique stayed successfully in situ during follow-up. Median pre-operative best-corrected visual acuity (0.75 logMAR; range 0.1-2.7) significantly improved to 0.5 logMAR post-operatively (p < 0.001). Moreover, 78% and 65% of the operated cases were within 1.0 and 0.5 diopters, respectively, from intended refraction. The most common complications were transient cystoid macular oedema (8.3%) and transient intraocular pressure rise (8.3%), all of which resolved within 2 months.
CONCLUSIONS: The proposed modification of sutureless scleral fixation of the CIL appears safe and effective. In our experience it is less time consuming and easier to perform than previous techniques and may therefore offer a useful future option.

Different techniques for artificial iris implantation with or without an intraocular lens, depending on lens status, are described in the literature. We describe a surgical technique for a custom-made artificial iris and toric-intraocular lens intrascleral flange fixation. We modified the \"Backpack\" artificial iris implantation surgical technique to facilitate an accurate alignment of the toric-intraocular lens in a patient with aphakia, aniridia, and high asymmetric astigmatism secondary to blunt trauma. Two months after the surgery, uncorrected visual acuity was 20/30, corrected to 20/25 with a refraction of -2.00 in the diopter sphere with no residual astigmatism. The artificial iris implant and toric-intraocular lens were well-centered. The patient was satisfied with the visual and cosmetic outcomes. This procedure, however, is not complication-free as our patient developed uveitis and increased intraocular pressure during the postoperative period, which was treated successfully.

OBJECTIVE: Evaluation of anterior segment parameters using the Scheimpflug corneal topography 1 year after surgery in patients who underwent sutureless scleral fixation intraocular lens (SFIOL) implantation using the modified Yamane technique and retropupillary iris-claw intraocular lens (RPIOL) implantation.
METHODS: A total of 60 eyes from 57 patients who underwent sutureless SFIOL implantation and 57 eyes from 52 patients who underwent RPIOL implantation were included. Anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), anterior-posterior corneal astigmatism, and keratometric values were assessed using the Scheimpflug corneal topography (Pentacam HR, Germany).
RESULTS: There was no statistically significant difference in postoperative UCVA and BCVA between the sutureless SFIOL and the RPIOL group (p = 0.236, p = 0.293, respectively). While there was no statistically significant difference in postoperative IOP between the two groups (p = 0.223), a statistically significant decrease in IOP was observed in both groups (p < 0.001). While there was no statistical difference between the sutureless SFIOL group and the RPIOL group in terms of spherical value (p = 0.441) and spherical equivalence (p = 0.237), there was a statistically significant difference in cylindrical value (p < 0.001). While there was a statistical difference in anterior astigmatism (p < 0.001), there was no statistical difference in posterior astigmatism (p = 0.405). There was no statistical difference in terms of ACV, ACD, and ACA between the sutureless SFIOL and the RPIOL group (p = 0.812, p = 0.770, p = 0.401, respectively).
CONCLUSIONS: In this study, although there was a statistical difference in cylindrical value and anterior corneal astigmatism between the sutureless SFIOL and RPIOL groups, vision was not affected. According to this study, sutureless SFIOL and RPIOL are two successful methods in terms of visual acuity, anterior segment, and keratometry outcomes in aphakic patients after phacoemulsification.

OBJECTIVE: To assess the refractive outcomes of secondary intraocular lenses (IOL) in patients with traumatic aphakic eyes with corneal penetrating injury and compare different corneal curvature measurement methods.
METHODS: Patients with unilateral penetrating eye injuries underwent corneal wound repair and cataract extraction, followed by secondary IOL implantation. Corneal curvature measurements were taken on the contralateral healthy eye (Group A), from the affected eye before removing corneal sutures (Group B), or after suture removal (Group C). The refractive outcomes were compared among the three groups.
RESULTS: The study included 261 eyes. The Mean Absolute Error (MAE) in Group C (0.99 ± 0.85 D) was significantly smaller than that in Group A (1.87 ± 1.71 D) and Group B (1.37 ± 1.20 D) (both P < 0.001). Moreover, the percentage of eyes with IOL prediction errors within ± 0.50 D in Group C (40%) was higher than that in group A (21.7%) (OR = 2.364, 95%CI: 1.272-4.392, P = 0.006) and group B (28.0%) (OR = 1.714, 95%CI: 0.948-3.099, P = 0.073), and the percentage of eyes with IOL prediction errors within ± 1.0 D in Group C (90.9%) was higher than that in group A (67.9%) (OR = 4.758, 95%CI: 2.131-10.626, P < 0.001) and group B (75.0%) (OR = 3.370, 95%CI: 1.483-7.660, P = 0.003) as well.
CONCLUSIONS: In traumatic aphakic eyes with corneal sutures, IOL power calculation based on the corneal curvature of the injured eye after removing the corneal sutures yields the best refractive outcomes.

OBJECTIVE: To determine retinal detachment (RD) risk factors after lens removal surgery in children with Marfan syndrome (MS).
METHODS: Retrospective, case control study.
METHODS: This was an institutional case series including children (age <18 years) with MS who underwent lens removal surgery. Clinical and surgical characteristics were extracted from the children\'s electronic files: age, axial length (AL), gender, number of surgeries received, intraocular lens (IOL) implantation at the first surgery, complete removal of the capsular bag, and final best-corrected visual acuity. Risk factors associated with RD occurrence were identified.
RESULTS: Among 158 eyes included (85 children), 35 eyes (22.2%) developed RD during follow-up. Bilateral detachment occurred in 11 patients (45.8%). Age at the time of the lens removal surgery was not different between groups. Children in the RD group had a higher AL (P < .001), longer follow-up, IOL implantation, and capsular residue. Multivariate analysis identified capsular residue (odds ratio, 16.8; 95% CI, 1.9-148.8; P = .01) and AL (odds ratio, 1.3; 95% CI, 1.01-1.7; P = .03) as predictors for RD.
CONCLUSIONS: Children with MS and increased AL were more likely to develop an RD after lens surgery. When considering lens removal surgery in a pediatric population presenting with MS, a complete capsular removal seemed to be the safer option regarding RD risk.

Background: The aim of this study was to evaluate the short-term efficacy and safety of the Paul Glaucoma Implant (PGI) in pediatric eyes diagnosed with glaucoma following congenital cataract surgery (GFCS). Methods: A retrospective, single-center, descriptive study was conducted on consecutive children diagnosed with GFCS who underwent PGI implantation between July 2022 and November 2023 at the University Medical Center Mainz. The primary outcome measure was the reduction in IOP at the last follow-up visit. Results: Ten eyes of nine children were included in the study. The mean follow-up time was 7.70 ± 4.22 months (4.68-10.72 months). At the end of the study follow-up, the mean (95% CI) reduction in IOP was -14.8 ± 8.73 mmHg (-8.56 to -21.04 mmHg, p < 0.001). At the last follow-up, 30.0% (3/10) of patients achieved an IOP (intraocular pressure) of ≥6 and ≤21 mmHg with a reduction in IOP of ≥25% without treatment, while 90.0% (9/10) achieved this target IOP regardless of glaucoma medication treatment. The mean number of antiglaucoma medications was significantly reduced from 3.50 (IQR = 1) to 2.0 (IQR = 2, p = 0.01), and the visual acuity logMAR improved from 1.26 ± 0.62 to 1.03 ± 0.48 (p = 0.04). Only one eye experienced numerical hypotony (4 mmHg) without choroidal detachment or anterior chamber shallowing within the first 24 h. No other adverse events were observed during the follow-up period. Conclusions: PGI implantation significantly lowered IOP and the number of antiglaucoma eye drops with a favorable safety profile in children diagnosed with GFCS, thereby achieving a high rate of qualified surgical success in the short term.

BACKGROUND: 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.
