RESUMO

BACKGROUND: A modified surgical technique of sutured scleral fixated intraocular lens (SSF-IOL) was applied in a patient with post-traumatic aniridia and aphakia. CASE PRESENTATION: A 51-year-old man was referred to our clinic with decreased vision (finger count) in his right eye. This patient had previously undergone primary repair of the ruptured globe and pars plana vitrectomy to manage ocular trauma in the same eye. On presentation, the best corrected visual acuity in his right eye was 20/40. The slit lamp examination of his right eye revealed loss of total iris and lens. Corneal endothelial cell density was 1462 cells/mm2. Fundoscopic examination of the right eye revealed a retinal attachment. For IOL implantation, a rigid poly methyl methacrylate IOL was used with a 2-point scleral fixation performed using a polypropylene suture. One year postoperatively, the uncorrected distance visual acuity was 20/32, and the manifest refraction was - 0.5/-1.5 × 130 (20/20). Pentacam revealed that the astigmatism of the anterior corneal surface and the total cornea was 1.1 D (axis: 59.8°) and 1.0 D (axis: 35.6°), respectively. The horizontal (3°-183°) cross-section image displayed an IOL with a 1° tilt and 0.425 mm decentration. The patient reported no dysphotopsia or photophobia and was satisfied with the visual results. OPD-scan III revealed that higher-order aberrations in the right eye were slightly higher than those in the left eye. No suture-related or other serious complications were observed. CONCLUSION: The modified SSF-IOL technique can offer improved visual quality for patients with aniridia and aphakia by ensuring proper IOL positioning and reducing astigmatism.

RESUMO

PURPOSE: 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). CONCLUSION: 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.

RESUMO

AIM: To compare the clinical outcomes between two approaches for sutureless scleral-fixated intraocular lens (SFIOL) in children with Marfan syndrome (MFS). METHODS: The study included 15 children (26 eyes) with lens subluxation due to MFS. These children underwent lensectomy, anterior vitrectomy, and sutureless SFIOL. According to the position of placement of intraocular lens (IOL) haptics, two study groups were reviewed for best corrected visual acuity (BCVA) and postoperative complications: group A, 14 eyes with haptics fixated at 2.0 mm from the limbus; group B, 12 eyes with the haptics fixated at 2.5 mm from the limbus. RESULTS: The mean axial length for all patients was 25.66±2.35 mm. Postoperative BCVA in logMAR were significant improved in both groups (0.77±0.32 to 0.17±0.12 in group A, 0.66±0.25 to 0.24±0.12 in group B, both P<0.001) while no significant difference between two groups (P>0.05). Pupillary capture was main postoperative complication, occurring between 3d and 18mo. It occurred in 7 eyes in group A and one eye in group B (P=0.02). CONCLUSION: Sutureless SFIOL is an effective treatment approach for lens subluxation in children with MFS. Pupillary capture is the main postoperative complication. Fixated IOL haptics at 2.5 mm from the limbus can reduce the occurrence of pupillary capture.

RESUMO

Purpose: To describe the application of the light adjustable lens (LAL) using an intrascleral haptic fixation (ISHF) technique for the correction of aphakia and post-operative refractive error. Observation: The LAL was placed using a modified trocar-based ISHF technique for visual rehabilitation following removal of bilateral cataracts in a patient with ectopia lentis. She ultimately obtained an excellent refractive outcome after adjustment with micro-monovision. Conclusions and Importance: Secondary intraocular lens placement has a much higher risk of residual ametropia than traditional in-the-bag lens placement. The ISHF technique with the LAL presents a solution for eliminating postoperative refractive error in patients requiring scleral-fixated lenses.

RESUMO

Suprachoroidal hemorrhage (SH) is a rare complication of scleral-fixated intraocular lens (SFIOL). In this series, we report three cases of sutureless SFIOL who developed SH postoperatively. Details of surgery, treatment, and outcome were analyzed. Two cases had limited SH which resolved with conservative treatment and had optimum visual recovery. One case developed massive SH needing surgical drainage, with final best-corrected visual acuity of 6/18 due to a persistent retinal fold. SH can be a potential complication while creating scleral grooves for haptic fixation. The use of a bent needle instead of a straight microvitreoretinal knife while creating scleral grooves might reduce the risk of SH in sutureless SFIOL surgeries.

RESUMO

Purpose. To revise the current literature on FIL SSF (Carlevale) intraocular lens, previously known as Carlevale lens, and to compare their outcomes with those from other secondary IOL implants. Methods. We performed a peer review of the literature regarding FIL SSF IOLs until April 2021 and analyzed the results only of articles with a minimum of 25 cases and a follow-up of at least 6 months. The searches yielded 36 citations, 11 of which were abstracts of meeting presentations that were not included in the analysis because of their limited data. The authors reviewed 25 abstracts and selected six articles of possible clinical relevance to review in full text. Of these, four were considered to be sufficiently clinically relevant. Particularly, we extrapolated data regarding the pre- and postoperative best corrected visual acuities (BCVA) and the complications related to the procedure. The complication rates were then compared with those from a recently published Ophthalmic Technology Assessment by the American Academy of Ophthalmology (AAO) on secondary IOL implants. Results. Four studies with a total of 333 cases were included for results analysis. The BCVA improved in all cases after surgery, as expected. Cystoid macular edema (CME) and increased intraocular pressure were the most common complications, with an incidence of up to 7.4% and 16.5%, respectively. Other IOL types from the AAO report included anterior chamber IOLs, iris fixation IOLs, sutured iris fixation IOLs, sutured scleral fixation IOLs, and sutureless scleral fixation IOLs. There was no statistically significant difference in the rates of postoperative CME (p = 0.20), and vitreous hemorrhage (p = 0.89) between other secondary implants and the FIL SSF IOL, whereas the rate of retinal detachment was significantly less with FIL SSF IOLs (p = 0.04). Conclusion. The results of our study suggest the implantation of FIL SSF IOLs is an effective and safe surgical strategy in cases where there is a lack of capsular support. In fact, their outcomes seem to be comparable to those obtained with the other available secondary IOL implants. According to published literature, the FIL SSF (Carlevale) IOL provides favorable functional results with a low rate of postoperative complications.

RESUMO

PURPOSE: To report a novel surgical approach for the scleral fixation of the Rayner 620 H intraocular lens (IOL) with Gore-Tex suture and its outcomes at 6 months postoperatively. METHODS: 19 consecutive patients who underwent novel surgical approach for the scleral fixation of Rayner 620 H IOL with Gore-Tex suture at Peking Union Medical College Hospital between June 2020 and June 2021 were included. Data on best-corrected visual acuity (BCVA), spherical equivalent, total astigmatism/axis, short-term and long-term complications, and corresponding management with a follow-up of 6 months were collected. RESULTS: Nineteen patients (11 men and 8 women) with a mean age of 62.7 ± 10.6 years were included. The median BCVA improved significantly from 0.90 ± 0.90 (Snellen 20/160) preoperatively to 0.20 ± 0.30 (Snellen 20/32) at postoperative 6 months follow-up (P < 0.001). The stratification of the accuracy of refractive outcomes was 53% of patients within ± 0.5 D and 84% of patients within ± 1.0 D of the refractive target. Corneal edema (n = 3, 16%) and increased intraocular pressure (IOP) (n = 4, 11%) were short-term complications. Long-term complications included increased IOP (n = 1, 5%), and macular edema (n = 1, 5%). CONCLUSION: The novel surgical approach for scleral fixation of the Rayner 620 H IOL with Gore-Tex suture is a reasonable option for patients who need secondary IOL placement without adequate capsular support.

RESUMO

PURPOSE: To describe the clinical features and visual outcomes of eyes with conjunctival haptic erosion after sutureless intrascleral (SIS) fixated intraocular lens (IOL) placement. DESIGN: Retrospective case series. SUBJECTS: Patients experiencing haptic erosion after SIS fixation between January 1, 2013, and March 1, 2022. METHODS: A multicenter, multisurgeon, retrospective review. MAIN OUTCOME MEASURES: Clinical features, visual outcomes, and treatment options following haptic erosions after SIS fixation. RESULTS: Nineteen eyes with haptic erosion were identified. The mean age at initial SIS fixation was 64 ± 12 years (range, 38-81 years). There were 5 (26%) eyes with a history of conjunctiva involving ocular surgery, including scleral buckle surgery and tube shunt surgery. Trocar-assisted fixation was performed in 15 (79%) eyes, whereas needle fixation was used in 4 (21%) eyes. Eighteen (95%) sets of haptics were flanged with a low temperature cautery. Seventeen (90%) sets of haptics were externalized superiorly and inferiorly, and 2 (10%) sets of haptics were externalized nasally and temporally. Haptics were covered by conjunctiva in 14 (74%) eyes and by scleral flap in 5 (26%) eyes. All patients experienced a single haptic erosion, of which 8 (43%) were located superiorly, 9 (47%) inferiorly, and 2 (10%) temporally. The mean interval between the initial SIS fixation and haptic erosion was 278 ± 437 days. After correction of the erosion, 18 (95%) eyes had a stable IOL at the last follow-up, with no recurrence of haptic erosion. In this series, there were no cases of endophthalmitis. CONCLUSIONS: Haptic erosion is a notable complication after SIS fixated IOL surgery but may be repaired with favorable visual outcomes. Careful evaluation of the conjunctiva should be considered before the surgery. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

RESUMO

Microspherophakia is a rare developmental abnormality of the crystalline lens with a myriad of ocular and systemic associations. Glaucoma is a serious complication associated with this disorder. Early identification of the disease, timely visual rehabilitation, and appropriate management of the lens and glaucoma can help us prevent blindness from this condition. Multidisciplinary care with lifelong follow-up is recommended, as this typically affects the younger population. Current treatment protocols for this condition are mainly based on case reports and retrospective studies with shorter follow-up. Due to the rarity of this disease, designing a large randomized controlled trial to identify the merits and demerits of each management strategy is challenging. With cataract, glaucoma, and vitreoretinal specialists, each having their preferred way of managing microspherophakic lenses, we decided to do a comprehensive review of the existing literature to devise an integrated approach toward effective management of these patients. This review will collate all evidence and provide a very practical decision-making tree for its management.

RESUMO

Purpose: To describe a case of an indolent, chronic Curvularia infection after a ruptured globe injury from an intraocular metallic foreign body in a 38-year old male. Following globe repair and vitrectomy, the patient underwent a sutured scleral-fixated lens. The patient subsequently presented with recurrent painless conjunctival erosion associated with small, pigmented skip lesions of the exposed suture. Observation: Indolent, chronic Curvularia infections can present with subtle signs, including small areas of suture exposure and pigmentation as well as and small ciliary body collections. Conclusion: Recurrent conjunctival erosion in cases of secondary sutured scleral fixated intraocular lenses should prompt evaluation for possible infectious etiology.

RESUMO

PURPOSE: The purpose of the study is to report the outcomes of sutureless, glueless multipiece posterior chamber intraocular lens (PCIOL) as scleral fixated intraocular lens (SFIOL) implantation in patients with poor or no posterior capsular support. METHODS: Medical records of 45 eyes of 42 patients who underwent SFIOL implantation where no suture or glue was used to fixate intraocular lens (IOL) to the sclera from November 2016 to October 2017, with minimum 18 months of follow-up were retrospectively analyzed. The best-corrected visual acuity, indication of surgery, other significant eye examination findings, and complications were analyzed. RESULTS: Out of 42 patients, 62% were males and 38% were females. Mean age of subjects was 48.5 ± 16.5 years (range 13-79 years). Mean preoperative and postoperative visual acuity was 1.48 ± 0.6 Logarithm of the Minimum Angle of Resolution (logMAR) units and 0.6 ± 0.3 logMAR units, respectively. Most common complication was vitreous hemorrhage six eyes (13.3%) followed by postoperative hypotony in five eyes (11.11%). Other complications such as transient postoperative intraocular pressure rise, hyphema, tilted IOL, cystoid macular edema, retinal detachment were also noted. CONCLUSION: Multipiece PCIOL used as SFIOL without any sutures and glue is a viable, cost-effective method of IOL implantation in eyes with aphakia following surgical complication or trauma, with comparable outcome to other techniques of SFIOL implantation.

RESUMO

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.

RESUMO

PURPOSE: To compare functional outcomes and complication rates of two scleral fixated intraocular lens implantation (SFIOL) techniques. METHODS: In this retrospective study, there were 30 eyes of 30 patients who underwent SFIOL implantation for dislocation of the IOL or crystalline lens. Group 1 (n = 17) comprised patients who received scleral-fixated polymethylmethacrylate (PMMA) IOL implantation through a self-sealing sclerocorneal tunnel with the suture burial technique, and group 2 (n = 13) comprised patients who received scleral-fixated foldable acrylic IOL implantation with a cartridge using a self-sealing clear corneal incision (CCI) with knotless Z-suture technique between 2014 and 2019. Surgical outcomes concerning safety, efficiency, visual function, induced astigmatism with vector analysis, and complications were compared. RESULTS: The indications were dislocated crystalline lens (n = 5/30), dislocated IOL (n = 17/30), and dropped nucleus (n = 8/30). The mean follow-up time was 50.65 ± 14.02 months in group 1 and 15.69 ± 3.71 months in group 2 (P < 0.001). The postoperative visual acuity improvement was statistically significant in both groups (P < 0.001). Surgically induced astigmatism was significantly higher in group 1 (2.68 ± 1.04 D) compared with group 2 (1.6 ± 1.0 D) at month 12 (P = 0.001). Postoperative complications included suture exposure (n = 1 in group 1) and cystoid macular edema (n = 1 in group 1; n = 1 in group 2). CONCLUSION: Both SFIOL techniques are safe and effective in the absence of adequate capsular support. However, the knotless Z-suture technique appears to be superior to the suture burial technique with regard to suture exposure-related complications. In addition, self-sealing CCI appears to be superior to self-sealing sclerocorneal tunnel with regard to surgically induced astigmatism.

RESUMO

PURPOSE: To describe a modified technique of haptic externalization for trocar-based sutureless scleral fixation of intraocular lenses, in order to avoid working with forceps in the iris plane in a manner that may be unfamiliar to the vitreoretinal surgeon. METHODS: This prospective, interventional case series included four eyes of four patients with dislocated intraocular lens (IOL). The modified haptic externalization technique avoids the pitfalls of iris-plane maneuvers by intentionally dropping the IOL onto the retina and using the forceps to grasp the tips of the haptics prior to direct externalization from the same grab. RESULTS: Four patients underwent scleral fixation of IOL using modified haptic externalization technique. One patient was lost to follow up after postoperative day 1. At the last follow up, all eyes demonstrated stability and good centration of scleral fixated IOL. All three patients achieved a best corrected visual acuity same or better compared to before the operation. One patient developed vitreous hemorrhage which later spontaneously resolved. CONCLUSIONS: The modified haptic externalization technique is a simple and quick modification using maneuvers familiar to vitreoretinal surgeons. It has demonstrated safety among a small pilot group of patients.

RESUMO

AIM: To evaluate the postoperative visual acuity and complications in eyes with ectopia lentis in children who underwent lens removal and then implantation of retropupillary fixated iris claw lens versus scleral fixated intraocular lens (SFIOL) implantation. MATERIALS AND METHODS: A retrospective analysis of pediatric cases who presented with lens subluxation secondary to ectopia lentis and who underwent lens extraction (57 eyes of 38 patients) with either retropupillary iris fixated intraocular lens (IOL) implantation (Group A - 36 eyes of 20 patients) and SFIOL implantation (Group B - 21 eyes of 18 patients) was done over a period of 5 years from March 2010 to February 2015. The main outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA) and secondary postoperative complications. RESULTS: The study patients were divided into two groups: Group A patients were implanted with retropupillary iris claw lens whereas Group B patients were implanted with SFIOL. The mean age of presentation was 12 years, the mean follow-up period was of 24 months (range 14-36 months), and the median follow-up period was 26 months in both the groups. An improvement in the mean BCVA (LogMAR) was seen in both the groups. In Group A, the mean BCVA improved from 1.5 ± 0.2 preoperatively to 0.3 ± 0.2 postoperatively, whereas in Group B, the mean BCVA improved from 1.5 ± 0.3 preoperatively to 0.3 ± 0.2 postoperatively (P < 0.001). None of the eyes in either of the groups had any serious complications such as glaucoma, uveitis, cystoid macular edema, or endophthalmitis. CONCLUSION: Retropupillary iris fixation and scleral fixation of IOL are both safe and viable options for the correction of ectopia lentis in pediatric age group.

RESUMO

We report our experience in the surgical technique of sutureless intrascleral posterior chamber intraocular lens (PC IOL) fixation in patients with insufficient capsular support using a uniquely designed, foldable, acrylic Carlevale IOL. It is specifically designed for sutureless scleral fixation and is equipped with a small plug attached to each of two haptics to anchor the lens to the sclera with a self-retaining mechanism. This surgery does not require creation of a scleral tunnel or transscleral exposure or excessive manipulation of the haptics. The harpoon-like plugs provide great stability to this implant, which can be injected through a 2.2mm incision. The characteristics of this IOL and the relative simplicity of this implantation technique makes it widely applicable in aphakic patients after previous complicated cataract surgery.

RESUMO

PURPOSE: To report the short-term outcomes of a modified small-incision technique for implantation of scleral-fixated intraocular lenses (IOLs) using Gore-Tex sutures. METHODS: A retrospective, interventional, consecutive case series was conducted. From June 2019 to February 2020, 10 patients underwent small-incision scleral-fixated IOL implantation using Gore-Tex sutures at a tertiary referral center. Visual and anatomical outcomes and complications were recorded with a minimum follow-up period of 3 months. Surgically induced astigmatism (SIA) and IOL-induced astigmatism were measured. RESULTS: The mean follow-up duration (range) was 396 (240-573) days. Best-corrected visual acuity improved significantly from logarithm of the minimal angle of resolution (logMAR) 0.88 ± 0.65 (Snellen equivalent: 20/153) preoperation to logMAR = 0.30 ± 0.51 (Snellen equivalent: 20/40) at final follow-up (P = .008). The estimated SIA and IOL-induced astigmatism were 0.61 diopters (D) ± 0.49D and 0.40D ± 0.36D, respectively. No intraoperative complications occurred. The postoperative complications, which included ocular hypertension (20%), cystoid macular edema (30%), and vitreous hemorrhage (20%), were transient and resolved with topical medication. CONCLUSIONS: The modified small-incision technique for implantation of scleral-fixated IOLs using Gore-Tex sutures was well tolerated in all patients, with favorable postoperative visual outcomes and minimal SIA and IOL-induced astigmatism.

RESUMO

Because the popularity of corneal refractive surgery has been increasing throughout the last 25 years, many authors have thought to apply optical coherence tomography (OCT) to the anterior segment (AS-OCT); by revising the instrumentation needed and slightly improve the technique, it has become an element of vital importance in order to ensure a complete and exhaustive pre- and postsurgical evaluation. Many applications of OCT have been recently developed-mostly in cataract surgery due to the increasing numbers-such as chamber biometry, which is used in a preoperative stage to determine the details of IOL implantation, and lens evaluation. The aim of this review is to assess the applications of anterior segment OCT in dislocated IOL and/or capsular bag exchange surgery with scleral sutureless fixated intraocular lens and monitoring of possible postoperative complications.

RESUMO

Scleral-fixated intraocular lens implantation in an important tool in the armamentarium of an ophthalmologist for managing aphakia. Various techniques have been described in the literature with variable learning curves. Herein, we describe an easy, fast, reproducible technique; the "MYX" technique, which utilizes the advantages of both the Yamane and the X-NIT technique, where the handshaking of the prolene haptic of a 3-piece PMMA IOL into the lumen of a 26-gauge needle is done externally (like in X-NIT technique), and the exteriorized haptic is cauterized to form a flange transconjunctivally, thereby avoiding the scleral pocket tucking (like Yamane technique), to achieve excellent surgical outcomes.

RESUMO

Purpose: To present the results of a modified sutured transcleral or sutureless intrascleral three-piece foldable intraocular lens (IOL) implantation with Descemet membrane endothelial keratoplasty (DMEK) in cases of aphakic bullous keratopathy (ABK) with inadequate capsular support.Methods: Twenty-one eyes of 21 patients with ABK and inadequate capsular support who underwent DMEK with three-piece foldable IOL implantation from September 2015 to June 2018 were analyzed, retrospectively. Two techniques were used in IOL implantation; sutureless intrascleral fixation of the IOL (ISF-IOL) and sutured transscleral-fixated IOL (TSF-IOL) implantation.Results: Rebubblings due to the graft detachment were needed in 9 (43%) of 21 eyes in the early postoperative period. At the last follow-up visit, 18 (85.7%) of DM grafts were attached. Any complication related to IOL implantation was not observed in the ISF-IOL cases. Exposure of the fixation suture in 1 (25%) of 4 TSF-IOL cases was seen, postoperatively. The increase in the mean best-corrected visual acuity (BCVA) at the last follow-up visit was statistically significant when compared to the mean preoperative BCVA (p < .001). The mean preoperative central corneal thickness was decreased from 883.3 ± 111.8 (700-1150) µm to 582.3 ± 118.2 (490-990) µm at the last follow-up visit (p < .001).Conclusion: DMEK combined with sutureless/sutured three-piece foldable IOL implantation appears to be a feasible method for the management in ABK without adequate capsular support. A faster visual recovery can be obtained with the techniques presented.
