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 flapless technique for two-point fixation of intraocular lens (IOL) with four fenestrated haptics. METHODS A transconjunctival puncture of 1-mL syringe needle was used to guide the suture needle out of the eye. The suture was taken out of the eye through the corneal incision, passed through the pair of fenestrated haptics of the IOL and then securely tied with overhand knots. The folded IOL was implanted into the posterior chamber. The anchor knots were created by both ends of the thread approximately 4 mm to 5 mm apart from the transconjunctival puncture and was intrasclerally buried. RESULTS The technique was used in 18 eyes (18 patients). The mean postoperative follow-up period was 17.22 ± 8.82 months. The IOLs of all the eyes remained well positioned and stable at the final follow-up. The visual acuities of all the eyes were improved postoperatively. No suture loosening, suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed in any of the patients. CONCLUSION The present technique provides minimal trauma and reliable stability for the two-point transscleral fixation of four fenestrated haptics IOL.

Abstract
PURPOSE To describe a technique for the replacement of dislocation of plate-haptic trifocal intraocular lens (IOL) through double-suture 4-point flange intrascleral fixation. DESIGN Retrospective, interventional, noncomparative, case series. METHODS A total of 7 eyes of 7 patients with a dislocated plate-haptic trifocal IOL were enrolled for 4-point flange intrascleral fixation with double 7-0 polypropylene suture. Preoperative and postoperative visual acuity, operating time, refractive results, postoperative IOL tilt and decentration, and intraoperative and postoperative complications were recorded. RESULTS The mean postoperative uncorrected distance visual acuity (UDVA) was 0.05 ± 0.06 logarithm of the minimum angle of resolution (logMAR). The mean postoperative uncorrected intermediate visual acuity (UIVA) at 80 cm was 0.09 ± 0.06 logMAR and the mean postoperative uncorrected near visual acuity (UNVA) at 40 cm was 0.06 ± 0.07 logMAR. The mean postoperative residual spherical equivalent values were -0.27 ± 0.39 diopters. The visual function index-14 questionnaire showed that no difficulty was found in >80% of subjects for all tasks. The mean surgical time was 16.23 ± 5.64 min. The mean tilt of IOL was 3.74° ± 1.31° and the mean decentration of the IOL was 0.18 ± 0.09 mm. No important complications appeared. CONCLUSION We have described the technique of 4-point flange intrascleral fixation for plate-haptic trifocal IOL.

Abstract
PURPOSE To determine the long-term anatomic outcomes and surgical complications of pars plana vitrectomy (PPV) and 4-point Gore-Tex-sutured Akreos AO60 intraocular lens (IOL) scleral fixation. DESIGN Retrospective, multicenter, multisurgeon case series. PARTICIPANTS Ninety-seven patients in tertiary eye care centers. METHODS The patients underwent PPV and intraocular fixation of the Akreos AO60 IOL using Gore-Tex CV-8 sutures between January 2015 and April 2020. The inclusion criteria were aphakia, no capsular support, and a minimal 1 year of follow-up. MAIN OUTCOME MEASURES Uncorrected visual acuity (VA), complication rates or types, and refraction. RESULTS Data from 101 eyes of the 97 patients were analyzed (mean follow-up duration, 33.4 months; range, 12-62 months). The mean ± standard deviation uncorrected logarithm of the minimum angle of resolution VA improved from 1.04 ± 0.73 (20/200 Snellen equivalent) before surgery to 0.66 ± 0.65 (20/80) at 6 months after surgery (P < 0.001). The most prevalent complications included hypotony (12.9%), ocular hypertension (12.9%), corneal edema (8.9%), cystoid macular edema (6.9%), and vitreous hemorrhage (5.9%). Refraction was measured between 3 and 6 months after surgery, and 61.8% of the patients had spherical equivalent of ± 2.0 diopters. Most complications occurred in the first postoperative month and resolved spontaneously or with medical treatment. CONCLUSIONS The results demonstrated that this surgical technique is well tolerated by the eyes, with a low complication rate in the long term. The rates of IOL opacification were infrequent for up to 62 months of follow-up.

[PMID: 37124064 PMCID: PMC10132900 DOI: 10.1155/2023/4032011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/05/2023] [Accepted: 03/22/2023] [Indexed: 05/02/2023] Open
Abstract
Purpose To evaluate refractive outcomes, intraocular lens (IOL) power calculation, and IOL position following a novel conjunctiva-sparing transscleral fixation technique. Methods Forty-one eyes of 40 patients managed with a flapless transscleral-sutured technique were included. Preoperative and postoperative refractive errors (spherical equivalents, SE) were compared. IOL position was assessed on the Scheimpflug images. IOL power was calculated by SRK/T, Holladay 1, and Hoffer Q formulas. Results The mean age was 57.39 ± 14.83 years (range: 26 to 79 years), and the mean follow-up was 7.46 ± 6.42 months (range: 1 to 24 months). Surgical indications were aphakia (n = 14), subluxated lenses (n = 3), and IOL dislocation (n = 24). The SE was 4.50 ± 6.38 diopter (D) (range: -3.75 to 13.75 D) preoperatively and -1.68 ± 1.57 D (range: -5.50 to 1.13 D) postoperatively (P < 0.001). The mean tilt angle and decentration were 2.90° ± 1.93° (range: 0.39° to 9.10°) and 0.23 ± 0.19 mm (range: 0.02 to 0.94 mm) vertically, and 1.75° ± 1.41° (range: 0.24° to 7.65°) and 0.18 ± 0.19 mm (range: 0.02 to 1.06 mm) horizontally, which were clinically insignificant. All three IOL formulas produced myopic errors (range: -0.29 to -0.50 D). The SRK/T had the lowest median absolute error (0.55 D), followed by the Holladay 1 (0.70 D) and the Hoffer Q (0.74 D). The three formulas had the same percentage of prediction errors (PEs) within ±0.5 D (43.48%), while the Hoffer Q had the highest percentage of PEs within ±1.0 D (82.61%). Conclusion The present technique can serve as an alternative approach for transscleral IOL fixation and refractive correction in eyes with compromised capsular support, ensuring the stability of IOLs and reasonable IOL power calculation accuracy.

Abstract
Introduction To compare the outcome of two different transscleral fixation approaches for posterior chamber intraocular lens (IOL) implantation, a two-point fixation of the Sensar (Allergan) or CZ70BD (Alcon) IOL and a four-point fixation of the Akreos Adapt (Bausch & Lomb) foldable IOL, for treatment of subluxated lenses in Marfan syndrome (MFS). Methods Fifty-three eyes of 33 consecutive patients with subluxated lenses secondary to MFS were studied. Eighteen patients with MFS (30 eyes) received two-point fixation of the Sensar (16 patients, 26 eyes) or CZ70BD (2 patients, 4 eyes) IOL, and 15 patients with MFS (23 eyes) received four-point fixation of the Akreos Adapt IOL. Preoperative and postoperative ophthalmologic examinations were performed. A primary outcome measure of postoperative complication was studied. Results The mean preoperative best corrected visual acuity (BCVA) in the two-point group was 0.68 ± 0.38 logarithm of the minimum angle of resolution (logMAR), and it improved to 0.30 ± 0.32 logMAR at the final follow-up (p < 0.05). The mean preoperative BCVA in the four-point group was 0.68 ± 0.45 logMAR, and it improved to 0.28 ± 0.28 logMAR at the final follow-up (p < 0.05). The BCVA results did not differ significantly between groups. The intraocular pressure was increased at the final follow-up in the two-point group (p < 0.05). Transscleral two-point fixation of IOL has relatively high incidences of pupillary capture of the IOL. Conclusion The closed continuous-loop transscleral four-point fixation of the Akreos Adapt foldable IOL is more suitable than two-point fixation of a two-haptic IOL in treating subluxated lenses due to MFS.

Abstract
Background While each scleral fixation method has its own advantages, there is a lack of strong evidence to suggest a superior technique. Advances in cataract surgery expand patient eligibility for successful cataract extraction, benefitting a growing population of pseudophakic patients. However, implantation of secondary intraocular lens (IOL) with compromised anterior or posterior capsule is a more challenging task. Each method of scleral fixation has its own advantages and none of them has strong evidence to be superior. This paper describes postsurgical outcomes of two scleral intraocular(IOL) fixation techniques combined with pars plana vitrectomy(PPV) from a single tertiary referral eye center. Methods Patients underwent PPV and IOL implantation with either four-point sutured scleral fixation (Akreos AO60(AK); n = 24) or two-point sutureless flanged intrascleral fixation (CT Lucia(CTL); n = 7). Reports include IOL and sclerotomy placement, fixation techniques, and IOL model. Results Thirty-one eyes of thirty patients were analyzed. Average change in vision from baseline measurement was LogMAR − 0.68 ± 0.66 and − 0.90 ± 0.63 for AK and CTL groups, respectively. Average postoperative refractive error was − 0.3 ± 1.03 D (AK) and 0.4 ± 0.60 D (CTL). No opacification cases of Akreos lens were found in this study with the longest follow up of 53 months. Conclusions Both methods of implantation (sutured and sutureless) could provide good visual and refractive outcomes. Minimal complication rates were reported despite including patients with multiple comorbidities, making both techniques an attractive choice for secondary IOL implantation.

Abstract
BACKGROUND AND OBJECTIVE To report the clinical outcomes of the flanged intrascleral haptic fixation technique (FIHFT) with the Zeiss CT Lucia 602 three-piece intraocular lens (IOL). PATIENTS AND METHODS This was a retrospective case series of patients who received FIHFT secondary implantation of the Zeiss CT Lucia 602 IOL from January 2018 to August 2020. Clinical and refractive outcomes were assessed including best-corrected visual acuity (BCVA), refractive prediction error, and complications. RESULTS Of the 22 patients in the series, 19 were included in the study. Mean vision improved from logarithm of the minimum angle of resolution (log-MAR) 1.14 to 0.54 (P = .03). BCVA of those without preoperative trauma improved from logMAR 0.68 to logMAR 0.25 (P = .02). Refractive spherical equivalent improved from 2.46 diopters (D) to 0.50 D (P = .07), but astigmatism increased from 1.09 D to 1.31 D (P = .67). CONCLUSIONS FIHFT with the Zeiss CT Lucia 602 three-piece lens is a safe and effective option for secondary IOL placement. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:658-662.].

Abstract
Varied options are available for the implantation of secondary intraocular lens implants in the absence of zonular or capsular support. Loss of the capsule can occur in the context of complicated cataract surgery, trauma or inherited conditions such as Marfan syndrome or pseudoexfoliation. Approaches to overcome this include optical measures such as the use of spectacles or contact lenses, and surgical therapy incorporating the use of anterior chamber, iris-fixated or scleral-fixated lenses. Surgical techniques to implant scleral-fixated lenses have undergone various modifications, since the first publication of sutured intrascleral fixation described in the 1980s. However, despite the advances in surgical techniques, studies are limited either by their retrospective nature, small sample size and most importantly small duration of follow-up. This comprehensive review aims to amalgamate the evolution of various surgical techniques with regards to intrascleral lens fixation and suggests areas for future development.

Abstract
Purpose To evaluate the efficacy and safety of the following three distinct surgical procedures for secondary IOL implantation without capsular support: Iris-claw lens, flanged transscleral fixated IOLs (Yamane technique), and sutureless transscleral hook IOL fixation (Carlevale IOL). Materials and Methods In this retrospective comparative study, three different sutureless IOL implantation techniques were compared in patients without any capsular support. Visual acuity and outcomes were analyzed in 24 eyes of 23 patients (14 male and 9 female). Study included 13 iris-claw lenses (Artisan Ophtec), 6 flanged transscleral fixated IOLs (Yamane technique using a MA60MA Alcon Inc IOL), and 5 transscleral Carlevale IOLS (Carlevale IOL, Soleko, Italy). Results logMAR mean best-corrected visual acuity (BCVA) improved from 0.49 ± 0.19 to 0.19 ± 0.10 at three months after surgery (p < 0.05). Postoperative BCVA was similar in all three groups, and no intergroup difference was noted. Three eyes (12.5%) had a raised IOP >25 mmHg, 2 eyes (8%) presented a subluxated/dislocated IOL, 4 eyes (16%) had corneal edema longer than 7 days, 3 eyes (12.5%) had irregular pupil profile, 2 eyes (8%) had vitreous hemorrhage, 7 eyes had (29%) corneal astigmatism over 3 diopters, and one patient (4%) developed cystoid macular edema (CME). Conclusions All three surgical procedures can be considered adequate to correct aphakia in patients without capsular support with significant improvement in visual acuity and low complication.

Abstract
To assess the safety of scleral fixation using the Akreos AO60 intraocular lens (IOL) and Gore-Tex suture. Prospective evaluation of 20 patients who underwent scleral fixation of an Akreos AO60 with Gore-Tex. Patients presenting with aphakia or dislocated IOL without capsular support were enrolled in the study. Main outcome measures included visual acuity, endothelial cell density, and postoperative complications over 6 months of follow-up. Mean ± standard deviation (SD) uncorrected logMAR visual acuity improved from 1.92 ± 0.23 (20/1600 Snellen equivalent) preoperatively to 0.80 ± 0.56 (20/125) at 6 months postoperatively (p < 0.001). Mean ± SD best-corrected visual acuity (BCVA) logMAR was 0.43 ± 0.23 preoperatively and 0.37 ± 0.24 (20/50) at 3-6 months postoperatively (p = 0.312). The mean ± SD endothelial cell density was 1740.50 ± 522.92 cells/mm2 and 1187.19 ± 493.00 cells/mm2 (p < 0.001) pre and postoperatively, respectively. Mean ± SD postoperative spherical equivalent was - 1.12 ± 1.50D. Postoperative complications included exposure of suture in 40% of the patients, hypotony in 15%, ocular hypertension in 10%, transient vitreous hemorrhage in 10%, retinal detachment in 5%, and transient lens opacification in 5%. Scleral fixation with an Akreos AO60 and Gore-Tex appears generally safe. However, given the high incidence of suture erosion observed, the use of scleral flaps or rotating and burying the knots is recommended in order to reduce the risk of this complication.

Abstract
Purpose To evaluate long-term outcomes and complications of sutured scleral-fixated foldable intraocular lens (IOL) implantation. Design Retrospective study. Methods Patients who underwent sutured scleral-fixated foldable IOL implantation using 10-0 polypropylene suture were followed up for at least 5 years at one Chinese tertiary hospital and two primary hospitals. Results 52 eyes among 48 patients (35 male and 13 female) were evaluated. The mean age (years) was 50.27 ± 20.08 (range: 6 to 81). The mean postoperative follow-up time (months) was 79.70 ± 18.84 (range: 60 to 121). The mean best-corrected visual acuity (BCVA) improved from 0.83 ± 0.69 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.50 ± 0.45 logMAR at the last follow-up visit. There was improved or unchanged BCVA in 44 eyes (84.62%) and reduced BCVA in 8 eyes (15.38%). Mild intraoperative intravitreal hemorrhage was observed in 3 eyes (5.77%). Early postoperative complications included transient elevated intraocular pressure (IOP) in 5 eyes (9.62%) and hypotony in 1 eye (1.92%). Secondary epimacular membrane occurred in 5 eyes (9.62%) and retinal detachment (RD; 3 years postsurgery), subconjunctival suture knot exposure (5 years postsurgery), and persistent elevated IOP (in a GRAVES patient) occurred in 1 eye (1.92%) each. No suture erosion or breakage nor IOL dislocation was observed. No visually threatening IOL tilt or decentration was reported in any patient. Conclusion Sutured scleral-fixated foldable IOL implantation demonstrated satisfactory long-term outcomes and rare suture-related complications. This technology was safe and did not require complicated equipment and is of considerable interest in the setting of aphakia without adequate capsule support.

Abstract
PURPOSE To characterize the true position of in-the-bag intraocular lenses (IOLs) relative to the limbus using ultrasound biomicroscopy and estimate scleral-sutured IOL positioning. METHODS This prospective single-center study included 70 eyes of 41 patients with in-the-bag posterior chamber IOLs. Four vertical ultrasound biomicroscopy captures were performed in each eye in the superior, inferior, nasal, and temporal quadrants. Postoperative biometric data were collected. The primary outcome was the vertical distance of the in-the-bag IOL from the sclerocorneal limbus. Secondary outcomes included anterior shift and refractive change of a theoretical scleral-sutured IOL using sclerotomies at 2.5 mm and 3 mm posterior to the limbus. RESULTS A total of 265 ultrasound biomicroscopy images were analyzed, including 64 superior, 69 inferior, 66 nasal, and 66 temporal. The true in-the-bag IOL position measured as distance posterior to the sclerocorneal limbus was 4.23 ± 0.56 mm superiorly, 4.22 ± 0.46 mm inferiorly, 3.95 ± 0.48 mm nasally, and 3.86 ± 0.52 mm temporally. The anterior shift of a theoretical scleral-sutured IOL was 0.60 mm for a 3-mm sclerotomy and 0.93 mm for a 2.5-mm sclerotomy, resulting in a theoretical myopic shift of 0.45 diopter (D) and 0.79 D, respectively, assuming a 15-D IOL. Larger biometric measurements correlated with a more posterior in-the-bag position. CONCLUSION True in-the-bag IOL position was found to be more posterior than estimates of scleral-sutured IOLs. Additional corrections in scleral-sutured IOL calculations may improve refractive outcomes.

Abstract
PURPOSE To evaluate the outcomes of a 4-point scleral-fixated foldable Akreos AO60 intraocular lens (IOL) insertion using Gore-Tex suture performed by trainees under supervision of a single attending surgeon. METHODS Retrospective chart review for 53 eyes of 50 patients whose surgery was performed by trainees under supervision of a single surgeon between 2015 and 2018 at a tertiary care hospital (Johns Hopkins Wilmer Eye Institute, Baltimore, MD). Indications for surgery, preoperative risk factors, and intraoperative techniques were analyzed. Outcome measures included final best-corrected visual acuity (BCVA), change in BCVA, difference between expected and final spherical equivalent (SE), and postoperative complications. RESULTS Mean patient age was 62.8 years (range 26.9 to 88.4). The most common indication for surgery was IOL dislocation (59.6%) due to trauma in 21 cases (40.4%) and pseudoexfoliation in 6 (11.5%). Combined pars plana vitrectomy was performed simultaneously in 46 cases (88.5%). Mean BCVA improved from 20/100 to 20/40 (p < 0.001). The difference between expected and final SE was within 1.0 D in 28 cases (53.8%). Postoperative hypotony occurred in 12 eyes (21.2%) on day 1; all were resolved at last follow-up. Postoperative cystoid macular edema (CME) occurred in 20 cases (38.5%); 11 (21.2%) persisted through last follow-up. CONCLUSION Scleral-fixation of Akreos AO60 IOL in absence of capsular support can be performed by trainees under supervision and results in effective visual rehabilitation. Postoperative CME occurred at a higher rate than previously reported in the literature. Future studies should assess the rates of postoperative complications amongst different techniques of secondary IOL fixation performed by trainees to determine which is the safest.

Abstract
Purpose To describe a flapless/grooveless technique for four-point refixation of a dislocated intraocular lens (IOL) with four fenestrated haptics. Methods An intraocular suture looping technique was performed with the assistance of two 27-gauge needles. A looping needle was passed into the eye through paracentesis and was used to loop both fenestrated haptics on the same side with an 8-0 polypropylene thread. A guiding needle was used to guide the looping needle out of the eye at the scleral fixation sites. After looping each pair of fenestrated haptics on nasal/temporal sides with 8-0 polypropylene sutures, the IOL was refixated by definitive knotting. The exterior suture ends were buried into the sclera without the creation of scleral flaps/grooves. Results The technique was employed in four eyes (three patients). The mean postoperative follow-up period was 13.8 ± 2.2 months. Postoperatively, the IOLs of all the eyes remained well positioned and stable. The postoperative visual acuities of all the eyes were improved. No suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed within the follow-up period. Conclusion The present technique provides minimal surgical invasion for the transscleral refixation of a dislocated IOL with four fenestrated haptics.

Abstract
Purpose We describe a minimally invasive suture fixation technique for four-point fixation of intraocular lenses (IOLs) in the treatment of aphakic eyes, namely, the intrascleral suture anchoring technique. Neither scleral flaps nor large conjunctival dissections are required. Methods This study included 11 eyes (11 patients). After looping the eyelets on the IOL haptics and externalizing the threads, the curved needle attached to the externalized thread was started with two sequential intrascleral passes from the first fixation point to reach the second fixation point. The same procedure was performed for the other side of the IOL. A fixation knot was created in the sclerotomy by the two ends of the thread to close the suture loop for IOL fixation. Another knot was created about 2 to 3 mm from the exiting point and was intrasclerally anchored by the aid of the attached curved needle. Results The mean postoperative follow-up period was 9.7 ± 5.8 months (range 5-15 months). The IOLs of all eyes remained well positioned and stable postoperatively. The postoperative visual acuities were improved. No suture erosion, suture loosening, hypotony, scleral atrophy, chronic inflammation, retinal tear, and/or detachment were observed within the follow-up period. Conclusion The present technique is an alternative, flapless method for the four-point suture fixation of IOLs. It provides both minimal surgical trauma and reliable stability.

Abstract
Purpose. To study the efficacy of a modified four-point fixation technique for the repositioning of a dislocated intraocular lens (IOL) with four eyelets in the absence of capsule support. Methods. Four patients with dislocated four-eyelet hydrophilic acrylic IOLs (Akreos AO60) were enrolled. The modified technique combined four-point fixation with intrascleral sutures and suture burying. The technique minimized the limbus incision to 1 mm with no externalization of the IOL or its haptics. Follow-ups included routine ophthalmic examinations, corneal endothelial cell counts, and measurement of IOL tilt and decentration (measured using Pentacam® HR images). Results. The IOLs were successfully repositioned in all cases. After a mean follow-up period of 19.75 ± 7.85 months (range: 8 to 24 months), the patients’ best-corrected vision acuity (BCVA (LogMAR), before: 0.63 ± 0.36, after: 0.58 ± 0.43,
) and intraocular pressure (pre 13.35 ± 0.85 mmHg, post 14.80 ± 2.03 mmHg,
) remained unchanged. Corneal endothelium density decreased about 6.84 ± 2.97%. In all cases, the IOL was well positioned during the follow-up. At the final visit, the average IOL tilt was 1.36 ± 0.35° horizontally and 1.31 ± 0.14° vertically. The average IOL decentration was 0.23 ± 0.12 mm horizontally and 0.18 ± 0.13 mm vertically. Conclusions. With this modified technique, dislocated IOLs with four-eyelets could be treated safely with favorable outcomes.

Abstract
BACKGROUND Scleral fixation of intraocular lenses has become a popular procedure for treating aphakia in the absence of capsular support. However, the lens formulas used to predict refractive outcomes were designed for in-the-bag lens placement. This study evaluates the accuracy of the SRK/T formula in predicting a target postoperative refraction when suturing a scleral-fixated intraocular lens (IOL) implant 3 mm posterior to the limbus. METHODS This is a retrospective, case series including 20 eyes of 20 patients who underwent scleral fixation of Akreos AO60 IOLs (Bausch & Lomb, Rochester, NY) by a single surgeon at the OSU Wexner Medical Center. Preoperative measurements were performed with optical biometry, and IOL power was calculated with the SRK/T formula. Following surgery, the actual refractive spherical equivalent (SE) was performed and compared with the preoperative prediction. Prediction error (PE), defined as the deviation of actual postoperative SE refraction in diopters (D) from preoperative predicted SE refraction, was the primary outcome measure. RESULTS The mean attempted (predicted) SE was - 1.12 D (± 0.87). Mean achieved SE was - 0.96 D (± 1.04). Mean PE (actual postoperative SE versus predicted preoperative SE) was 0.16 D (± 0.69). A total of 9 eyes (45%) were within ± 0.5 D of the predicted SE, 16 eyes (80%) were within ± 1.0 D, and all 20 eyes (100%) were within ± 1.5 D. CONCLUSION IOL power calculation using the SRK/T formula with optical biometry demonstrates reliable postoperative refractive outcomes in patients undergoing scleral fixation of an IOL (Akreos AO60). Further studies are needed to refine the predictive value of the SRK/T and other formulas for application in scleral fixation of IOLs.

Abstract
PURPOSE To report refractive outcomes of scleral-fixated intraocular lens (IOL) implantation with Gore-Tex (W.L. Gore & Associates, Newark, DE) suture and combined pars plana vitrectomy and compare predicted refractive outcomes among 5 IOL power calculation formulas. DESIGN Retrospective case series. PARTICIPANTS Patients undergoing scleral-fixated IOL implantation with Gore-Tex suture at our institution between January 2015 and June 2018. METHODS Comparison of preoperative biometrics with postoperative refraction and calculation of predicted refractive outcome with 5 different IOL formulas. MAIN OUTCOME MEASURES Prediction error and absolute error to compare postoperative refraction with refraction predicted by lens power calculation formulas. RESULTS Thirty-one eyes of 31 patients were included. All power calculations assumed in-the-bag position of the IOL. The Akreos A060 (Bausch & Lomb, Rochester, NY) was implanted in 23 eyes and the CZ70BD (Alcon, Fort Worth, TX) in 8 eyes, and all lenses were sutured 3 mm behind the limbus. Average postoperative spherical equivalent (SE) was -0.79±0.95 diopters (D). Average prediction error (postoperative SE refraction minus target refraction) was -0.19±0.72 D. Postoperative SE was within 1.0 D of target in 25 of 31 patients (81%) and 2.0 D of target in 31 of 31 patients (100%). The repeated-measures analysis of variance of absolute error by lens power formula was significant (P = 0.012), with Haigis demonstrating greater error. There was no significant difference among Barrett II, Sanders-Retzlaff-Kraff theoretical (SRK/T), Holladay 2, or Hoffer Q. CONCLUSIONS For eyes undergoing pars plana vitrectomy with scleral-sutured IOL implantation, assumption of in-the-bag IOL position when calculating lens power leads to acceptable refractive outcomes. Barrett II, SRK/T, Holladay 2, and Hoffer Q formulas were noninferior to each other.

Abstract
Objective: To explore the simplified technique for transscleral fixation of a foldable posterior chamber intraocular lens (IOLs) in patients with aphakia or inadequate posterior capsule support. Methods: A review was conducted of 18 eyes of eighteen patients with the absence of-or inadequate-capsule support, after the simplified technique of using a foldable posterior chamber intraocular lens (PC IOLs) with stable four-point transscleral fixation, as performed by a skilled surgeon. This technique uses only a single suture and a knot to fix a PC IOL firmly without creating a scleral flap. The mean follow-up time was 18 ± 5.8 months (ranging from 12 to 24 months). Results: All patients exhibited improved visual acuity. No IOL tilt or dislocation or iris capture was observed, and all patients exhibited stable and centered IOL after surgery. No complex complications, such as suture shedding and exposure, corneal endothelial decompensation, persistent uveitis, or retinal detachment and endophthalmitis were observed. Conclusion: The simplified technique proposed here is a reliable, economical, and reproducible method of treating patients with aphakia or inadequate posterior capsule support. It provides excellent IOL stability, reduces surgical duration and complexity, and prevents certain complications.

Abstract
Background To evaluate the safety and efficacy of combined 23-gauge transconjunctival pars plana vitrectomy and scleral fixation of intraocular lens (IOL) without conjunctival dissection. Methods A retrospective study in Chang Gung Memorial Hospital, Keelung and Taoyuan, Taiwan. Patients receiving combined 23-gauge transconjunctival pars plana vitrectomy and scleral fixation of IOL without conjunctival dissection were enrolled. The ocular findings, causes of lens complication, surgical procedures, type of IOL used, and complications were documented. Results We included 40 eyes from 39 patients (27 male, 12 female) with a mean age of 59.5 [standard deviation (±) 14.8] years old. The mean follow-up duration was 6.8 ± 5.4 months. The cause of lens complications was ocular trauma in 24 (60%) eyes, cataract surgery complications in 11 (28%) eyes, and spontaneous subluxation of crystalline lens in 5 (13%) eyes. The overall best corrected visual acuity (BCVA) (logMAR) improved from 1.359 ± 0.735 to 0.514 ± 0.582 (p < 0.001). The BCVA also improved significantly in each group with different causes of lens complications. Preoperative BCVA was the only factor associated with the postoperative visual outcome (p = 0.008). Most surgery-related complications were self-limited, including mild vitreous hemorrhage (5%), microhyphema (5%), transient elevated intraocular pressure (3%), and transient hypotony (3%). Cystoid macular edema and IOL decentration was found in 3 (8%) eyes and 1 (3%) eye respectively. Conclusions Combined 23-gauge transconjunctival vitrectomy and scleral fixation of IOL without conjunctival dissection is effective and safe in managing a wide variety of lens complications, with good postoperative comfort and visual recovery.

Jpn J Ophthalmol 2018; 62:365-372. [PMID: 29464488 DOI: 10.1007/s10384-018-0579-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2017] [Accepted: 01/21/2018] [Indexed: 12/01/2022]
Abstract
PURPOSE The purpose of this study is to describe a new technique for small-incision scleral fixation of intraocular lens (IOL) using double 10-0 polypropylene sutures, and to report the outcomes of IOL position compared with intrascleral IOL fixation at 12-month follow-up. STUDY DESIGN A retrospective comparative study. METHOD This new technique, called double sutured scleral fixated-IOL (DSF-IOL), was created to help with long-term knots strengthening by applying double sutures to each IOL haptic using an augmented Clove-hitch knot instead of the conventional knots tied by single suture. The tilt and decenter of IOL were measured by Scheimpflug camera and other refractive outcomes were compared between two groups at 12-month follow-up. RESULTS This study consisted of 26 eyes (54.2%) from the DSF-IOL group, and 22 eyes (45.8%) from the intrascleral fixated IOL (ISF-IOL) group. No significant differences of mean absolute degree of IOL tilt (2.90 ± 0.77 vs 2.82 ± 0.72; p = 0.633) and IOL decenter (151.90 ± 59.80 vs 175.0 ± 73.14 microns; p = 0.265) were found between the two groups. Post-operative LogMAR visual acuity was not statistically different between the two groups (0.32 ± 0.17 vs 0.41 ± 0.19, p = 0.089). Early post-operative hypotony was only present in the ISF-IOL group (13.6%). CONCLUSION This study shows that DSF-IOL is as effective as ISF-IOL. This technique can be a simpler approach to optimize small-incision scleral fixation of IOL without the complications associated with intrascleral IOL fixation.

Clinical outcomes of combined pars plana vitrectomy and trans-scleral 4-point suture fixation of a foldable intraocular lens. Eye (Lond) 2018; 32:1055-1061. [PMID: 29398696 DOI: 10.1038/s41433-018-0018-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2017] [Revised: 11/28/2017] [Accepted: 12/05/2017] [Indexed: 11/08/2022] Open
Abstract
OBJECTIVE To describe outcomes of combined pars plana vitrectomy (PPV) and trans-scleral 4-point suture fixation of a foldable Akreos AO60 intraocular lens (IOL) in eyes with subluxated or dislocated lens or IOL. METHODS Retrospective case series of 20 eyes of 18 patients who underwent this procedure with a minimum follow-up of 3 months. Outcome measures included final best-corrected Snellen visual acuity (BCVA), spherical equivalent (SE) and intraoperative and postoperative complications. RESULTS Mean age at surgery was 43.65 years. The commonest indication for surgery was post-traumatic subluxated or dislocated cataract. Mean BCVA improved from 6/24 preoperatively to 6/9 at final follow-up (p < 0.0001). Mean SE was 5.69 dioptres preoperatively and -1.32 dioptres postoperatively. There were no intraoperative complications. Postoperative complications included transient vitreous haemorrhage in one eye and cystoid macular oedema in one eye. Postoperative Pentacam analysis confirmed the absence of IOL tilt or decentration in six eyes. Mean follow-up was 8.9 months (range 3-30 months). CONCLUSION Trans-scleral 4-point suture fixation of a foldable Akreos AO60 IOL can be performed safely along with concurrent PPV across varying surgical indications resulting in a substantial improvement in visual acuity with minimal complications.
