Visual outcomes following Artisan aphakia iris claw lens implantation

Visual and refractive outcomes following secondary intraocular lens implantation

PURPOSE

To analyze the visual and refractive results after secondary IOL implantation using different surgical techniques - iris-claw aphakic IOL through a corneal incision or scleral tunnel, and 3-piece IOL into the ciliary sulcus.

PATIENTS AND METHODS

Retrospective study including patients that were submitted to secondary IOL implantation from January 2017 to December 2019 at the Department of Ophthalmology of Hospital de Braga, Portugal. We collected demographic data (age, surgical indication, comorbidities, surgical technique, IOL implanted, and intra and postoperative complications) and visual and refractive data [preoperative and 3-month, 6-month, and 12-month postoperative corrected-distance visual acuity (CDVA), spherical equivalent (SE), manifest cylinder, and intraocular pressure].

RESULTS

128 eyes from 123 patients were included. The most frequent surgical indications were IOL subluxation/luxation (62.5%) and intraoperative posterior capsular rupture (23.4%). CDVA improved from 1.26 ± 0.51 to 0.47 ± 0.49 logMar (p < .001). CDVA was significantly better in the 3-piece into the ciliary sulcus IOL group than both other groups. The final SE was -0.68 ± 0.94 diopters. The mean manifest refractive cylinder remained stable until the 6th month after the surgery (p = .454) and improved in the last 6 months of follow-up (p = .015). In the postoperative period, the cylinder was higher in the corneal incision iris-claw aphakic IOL group and lower in the 3-piece IOL into the ciliary sulcus group (p < 0,05). The corneal incision iris-claw aphakic IOL group presented the most postoperative complications.

CONCLUSION

All techniques showed satisfying results. The 3-piece IOL into the ciliary sulcus group showed the best visual and refractive performance, followed by the scleral tunnel iris-claw IOL group and the corneal incision iris-claw IOL group.

Descemet Stripping Endothelial Keratoplasty in Microcornea for Pseudophakic Bullous Keratopathy With Anterior Chamber Intraocular Lens

To report a case of bilateral pseudophakic bullous keratopathy (PBK) in a patient having bilateral microcornea with pre-existing anterior chamber intraocular lens (ACIOL) who underwent Descemet stripping endothelial keratoplasty (DSEK) with a successful postoperative visual outcome. A 36-year-old female, diagnosed with microcornea and congenital cataract in both eyes underwent lens aspiration sequentially followed by ACIOL implantation in both eyes. The patient reported to our centre and was diagnosed with bilateral PBK with ACIOL with microcornea. She also had associated secondary glaucoma, postoperative chronic uveitis, and hyphaema, which were controlled with medical management first and taken into consideration while planning DSEK. The patient underwent manual DSEK without intraocular lens exchange under local anaesthesia in both eyes sequentially with a good visual recovery postoperatively in both eyes. Descemet stripping automated endothelial keratoplasty (DSAEK)/DSEK seems a viable option in patients with microcornea who develop PBK following cataract surgery with retained ACIOL where there is absence of capsular support as well as deficiency of iris tissue.

Clinical outcome and endothelial loss following prepupillary and retropupillary implantation of iris claw intraocular lenses

PURPOSE

Iris claw intraocular lenses (IOLs) were successfully used for the management of aphakia in patients that lack capsular support. The aim of this study was to compare the clinical outcome of prepupillary and retropupillary implantation of these IOLs.

METHODS

The files of the 26 patients that had an iris claw IOL implantation between 2010 and 2020 were retrospectively reviewed. Detailed ophthalmological examination findings including corrected distance visual acuity (CDVA), intraocular pressure, endothelial cell counts, slit lamp and dilated fundus examination findings were specifically tabulated. Intraoperative and postoperative complications were also specifically recorded.

RESULTS

There were 18 patients in the prepupillary implantation group and eight patients in the retropupillary implantation group. Age and gender distribution were similar between the groups. CDVA significantly increased in prepupillary and retropupillary implantation groups (p = 0.001 and p = 0.012, respectively). Median endothelial cell loss was 6.7% in prepupillary group and 7.2% in retropupillary group. The only intraoperative complication was iridodialysis (n = 1). Postoperative complications included retinal detachment (n = 1), cystoid macular edema (n = 2) and IOL tilt (n = 1). All of these complications occurred in the prepupillary implantation group.

CONCLUSION

Prepupillary and retropupillary implantation of iris claw IOLs resulted with similar visual gain and endothelial loss rates in a follow-up time of 6 months. There was an insignificant trend toward a reduced complication rate following retropupillary implantation.

Iris-Claw Intraocular Lens Implantation in Various Clinical Indications: A 4-Year Study

An iris-claw intraocular lens (IOL) has been widely used as a secondary implant in aphakic patients. The study presents the results of implanting the anterior chamber iris-claw Artisan IOL in cases of where an appropriate posterior capsular support is lacking. The study included 132 patients subjected to primary IOL implantation during complicated cataract surgery with damage to the posterior capsule (I), secondary implantation in aphakia (II), secondary implantation during penetrating keratoplasty (III), and secondary implantation during pars plana vitrectomy with luxated IOL extraction (IV). We analyzed the records of best-corrected visual acuity (BCVA), spherical equivalent (SE), intraocular pressure (IOP), and corneal endothelial cell count (cECC), taken before and 1, 2, 3, and 4 years after the surgery. BCVA depended on the time after IOL implantation and the primary indication. Four years post-surgery, the SE values were the lowest in group III. IOP was the same in all groups both before and after the surgery, but 4 years after the surgery IOP values in group IV were higher than in group III. The cECC decreased every year after the surgery in all groups, but four years after the IOL implantation, the lowest cECC values were observed in group IV. At the same time, all groups of patients showed improved BCVA, stable refraction, and a low percentage of postoperative complications.

Surgical Outcomes of Retropupillary-Fixated Iris-Claw Intraocular Lens

Purpose:

To assess the visual outcome and complications following retropupillary-fixated iris-claw intraocular lens (IOL) implantation.

Methods:

For this retrospective, non-comparative study, chart review of patients who underwent retropupillary iris-claw IOL implantation for the correction of aphakia from July 2014 to October 2018 and had a minimum postoperative follow-up of 2 months was carried out. Postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), and complications were noted.

Results:

One hundred and twenty-two eyes of 122 patients (mean follow-up: 7.48 ± 5.2 months, range, 2 months-3.5 years) were enrolled in the study. The mean logMAR CDVA improved from 1.36 ± 0.52 preoperatively to 0.5 ± 0.42 postoperatively, at the last follow-up visit (P < 0.0001). The final CDVA improved in 110 eyes (90.2%), remained unchanged in 8 eyes (6.6%), and worsened in 4 eyes (3.3%). In cases of pre-existing cystoid macular edema (CME) or excessive intraoperative manipulations, 0.05 ml of 4 mg intravitreal triamcinolone acetonide (IVTA) was injected at the end of the surgery. Twenty eyes (16.4%) had transient ocular hypertension (OHT), 6 eyes (4.9%) had persistent OHT, and 2 eyes (1.6%) progressed to glaucoma. Choroidal detachment was noted in 2 eyes (1.6%), CME in 6 eyes (4.9%), 2 eyes (1.6%) had retinal detachment, 20 eyes (16.4%) had significant ovalization of pupil, 8 eyes (6.6%) had one haptic disenclavation, 1 eye (0.8%) had corneal decompensation, and 1 eye (0.8%) had endophthalmitis.

Conclusions:

Retropupillary iris-claw IOL provides good visual rehabilitation with a few complications. Its ease of insertion and short surgical time makes it a good option to correct aphakia in patients with an inadequate capsular support.

Five-year follow-up of secondary iris-claw intraocular lens implantation for the treatment of aphakia: Anterior chamber versus retropupillary implantation

BACKGROUND

Though several procedures of IOL implantation have been described (sutured scleral fixation, intra-scleral fixation, angle-supported anterior chamber, and anterior chamber or retropupillary iris-claw IOLs), there are no randomized trials which are comparing different techniques. Hence, the surgical treatment of aphakia still remains controversial and challenging. The purpose of this study was to compare the long-term efficacy and the rate of complications of anterior versus posterior Iris-claw intraocular lenses (IOL) implantation to correct for the treatment of aphakia without sufficient capsule support.

METHODS AND FINDINGS

Consecutive eyes having secondary implantation of aphakic iris-fixated IOLs with a follow-up of at least 5 years were considered. Mean correct distance visual acuity (CDVA) changes, percentage of eyes with CDVA improvement, mean corneal endothelial cell density (CECD) loss and the rate of other complications were used for statistical analysis. The study evaluated a total of 180 eyes (Group A: 87 anterior chamber iris-claw fixation, Group B: 93 retropupillary iris-claw implantation) of 180 consecutive different patients, with aphakia of various reasons. CDVA improved significantly in both groups after surgery (P<0.001, ANOVA), and was remarkably higher than baseline in both groups from first week and during the entire follow-up (P<0.001, Tukey's Honest Significant Difference). There was no statistically significant difference in CDVA between the two groups during each follow-up visits (P = NS, unpaired t-test) and in the CDVA improvement percentage between the two groups (P = 0.882, Chi-square test). No significant changes in CECD were noted after surgery in both groups (ANOVA Group A: P = 0.067, Group B: P = 0.330P). No intra-operative complications occurred in both groups. There was no statistically significant difference in the rate of complications between the two groups (P = NS, Chi-square test), except for pigment precipitates which were higher in Group A (P<0.05, Chi-square test).

CONCLUSIONS

Five-year follow-up shows that secondary implantation of aphakic IOLs is effective and safe for the correction treatment of aphakia in eyes without capsule support.

Calculation of iris-claw IOL power for correction of late in-the-bag IOL complex dislocation

Background

To assess the constants and formula for aphakia correction with iris-claw IOLs to achieve the best refractive status in cases of late in-the-bag IOL complex dislocation.

Methods

A literature search was performed. The following data were obtained: Iris-claw IOL model, Iridal or retroiridal enclavation, A-constant, ultrasound or optical biometry, formula employed and refractive outcomes. Acceptable emmetropia was considered if the resulting spherical equivalent (SE) was within ±1.00 D.

Results

The majority of the studies used SRK/T formula (66.6%). The 88.9% of the reports obtained a SE within ±1.00 D. Using A-115 for ultrasound biometry and A-115.7 for optical biometry and SRK/T formula, the emmetropia (±1.00 D) of SE, was able to get near 100% of reported cases over the pupil implantation. However, the emmetropia decreased to 80% when the enclavation is retropupilar using the same formula. The A-constant can vary from 116.7 to 117.5 for retropupilar enclavation.

Conclusions

Using A-115 for ultrasound biometry and A-115.7 for optical biometry and SRK/T formula, ±1.00 D of SE, is able to get near 100% of cases. Nevertheless, ±1.00 D of SE decreased to 80% of the cases when the enclavation is retropupilar.

Unilateral Iris-Claw Intraocular Lens Implantation for Aphakia: A Paired-Eye Comparison

PURPOSE

To perform a paired-eye comparison of secondary iris-claw intraocular lens (IOL) implantation for aphakia.

METHODS

Retrospective, comparative, nonrandomized interventional case series of aphakic eyes, which underwent secondary iris-claw Artisan IOL (Ophtec BV) implantation for aphakia in one eye and no surgery (group 1) or cataract surgery (group 2) in the fellow eye. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent, central endothelial cell count (cECC), and complications were evaluated before surgery, and at yearly intervals up to 5 years.

RESULTS

Thirty aphakic eyes implanted with the Artisan were included, and the fellow eyes served as controls. In group 1, postoperative logMAR UDVA and CDVA was significantly higher in the Artisan-implanted eyes (P < 0.01). In group 2, no differences were found in postoperative UDVA and postoperative CDVA between the Artisan-implanted eyes and the eyes that underwent cataract surgery throughout the follow-up (P ≥ 0.05). No statistically significant differences were found in postoperative spherical equivalent between the Artisan-implanted eyes and unoperated eyes or eyes that underwent cataract surgery (P ≥ 0.05). In group 1, cECC was significantly lower in the Artisan-implanted eyes [1973 ± 822 vs. 2616 ± 481 cells per square millimeter at 2 years (P < 0.01)] throughout the follow-up (P < 0.01). In group 2, cECC was not significantly lower in the Artisan-implanted eyes (P ≥ 0.05) [1934 ± 689 vs. 2058 ± 818 cells per square millimeter at 2 years (P = 0.67)].

CONCLUSIONS

Visual rehabilitation with secondary iris-claw IOL implantation in aphakic eyes without capsular support seems to be an effective and safe procedure. As expected, uncomplicated cataract surgery with posterior chamber IOL implantation showed lower endothelial cell count loss. Close monitoring of the corneal endothelium is mandatory.

Primary iris claw IOL retrofixation with intravitreal triamcinolone acetonide in cases of inadequate capsular support

PURPOSE

To assess the outcomes and analyze complication rates following primary iris claw IOL retrofixation with intravitreal triamcinolone acetonide.

METHODS

This is a retrospective interventional case series. Patients with poor capsular support-diagnosed preoperatively or owing to intraoperative complications-were treated with iris claw IOL retrofixation with intravitreal triamcinolone acetonide. The data were retrospectively analyzed.

RESULTS

104 eyes of 102 patients with poor capsular support who underwent the procedure between 2010 and 2013 were analyzed. The minimum follow-up period was 12 months (ranging from 12 to 36 months). Iris claw IOL was implanted in-traumatic subluxated cataracts-24 cases (23.07%), non-traumatic subluxated cataracts in 16 cases (15.38%), or as a complication of cataract surgery-intraoperative posterior capsular rent in 48 cases (46.15%) and intraoperative nucleus drop in 16 cases (15.38%). The final mean best-corrected logMAR visual acuity improved from 1.36 ± 0.64 preoperatively to 0.36 ± 0.32 at 1-year follow-up. Complications included pupil ovalization in 11 cases (10.57%), transient elevation in intraocular pressure in 7 eyes (6.73%), postoperative hypotony in 5 eyes (4.80%), cystoid macular edema in 2 eyes (1.92%), retinal detachment in 1 eye (0.96%), vitreous hemorrhage in 1 eye (0.96%), and hyphema in 1 eye (0.96%).

CONCLUSION

Primary iris claw IOL retrofixation provided excellent alternative in patients with inadequate capsular support. The visual outcomes were good along with favorable rates of complications. The addition of triamcinolone acetonide helps in reducing the chances of cystoid macular edema.

Iris-claw intraocular lens implantation: Anterior chamber versus retropupillary implantation

Purpose:

To compare the outcomes of anterior chamber and retropupillary implantation of iris-claw Artisan intraocular lenses (IOL).

Design:

Prospective, randomized, single-blinded study.

Patients and Methods:

Forty eyes of forty aphakic patients were enrolled. Patients were randomized into two groups. Each group includes twenty patients. Group 1 received anterior chamber Artisan IOL implantation. Group 2 received retropupillary Artisan IOL implantation. Preoperative and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), and all complications were noted and compared at 6 months follow-up.

Results:

Each two groups obtained a significant improvement in CDVA (P < 0.05). Four patients in Group 1 and five patients in Group 2 had significant but nonpermanent increase at IOP values. There were one and two pupillary irregularity in Group 1 and Group 2, respectively. In one patient, a shallow and inferior located retinal detachment were encountered in anterior chamber group.

Conclusions:

The results were not significantly different between the two fixation techniques for iris-claw lens. The surgery procedure is dependent to surgeon experience and eye's conditions.

Iris-claw versus posterior chamber fixation intraocular lens implantation in pediatric traumatic cataract

Aim:

This study aims to compare visual outcomes and complications of iris-fixated (claw) intraocular lens (IFIOL) implantation with those of posterior chamber intraocular lens (PCIOL) implantation in children with traumatic cataract.

Settings and design:

Retrospective observational clinical audit.

Materials and methods:

A total of 50 pediatric traumatic cataract cases that underwent lens removal and IOL implantation (IFIOL or PCIOL) with or without corneal or corneoscleral tear repair between January 2009 and December 2013 were analyzed. After meeting the eligibility criteria, their pre- and postoperative visual outcomes and complication rates were recorded. Data were analyzed descriptively.

Results:

Out of 50 children, IFIOL and PCIOL implantations were performed in one eye of each of 25 children. Their mean age was 11 ± 4 years (range 4–18 years). Primary (cataract removal with lens implantation) and secondary (corneal tear repair followed by cataract removal with lens implantation) procedures were performed in 19 (76%) and six (24%) children in the IFIOL group and in 21 (84%) and four (16%) children in the PCIOL group, respectively. There was an improvement in best corrected visual acuity postimplantation in both the IFIOL and the PCIOL group, and no significant difference in the logarithm of the minimum angle of resolution of best corrected visual acuity was observed between the two groups over 36 months. Only three eyes in the IFIOL group developed complications: one eye developed secondary glaucoma, one disenclavation of IOL haptic, and one cystoid macular edema.

Conclusion:

Both IFIOL and PCIOL implantations have good visual outcomes and minimal postoperative complications; therefore, IFIOL can be used as an alternative to PCIOL in children with traumatic cataract with inadequate capsular support.

Long Term Clinical and Visual Outcomes of Retrofixated Iris Claw Lenses Implantation in Complicated Cases

Aims:

To evaluate the visual outcomes and complications after implantation of retrofixated iris claw (RFIC) lens in various challenging situations.

Settings and Design:

Retrospective, single centre, 8 year clinical audit.

Materials and Methods:

A retrospective analysis of cases who underwent RFIC lens implantation alone (group 1) or in combination with vitreoretinal (VR), corneal or glaucoma procedures (group 2) was performed. The main outcomes evaluated were corrected distant visual acuity (CDVA) and postoperative complications. The mean follow up was 13.09±6.8 (range 6-24) months.

Results:

The study involved 100 eyes of 83 patients with mean age of 51.1±25.4 years. Group 1 included 59 eyes and group 2 had 41 eyes. In group 1, the mean CDVA improved from 0.86±0.81 to 0.38±0.51 LogMAR (p<0.001) with 72.8% eyes having gain in lines (≥ 2 lines) of CDVA with safety index of 1.73. The mean CDVA in group 2 improved from 0.71±0.65 to 0.38±0.34 LogMAR (p=0.003) with 65.8% eyes having gain in lines (≥ 2 lines) of CDVA with a safety index of 1.54. Group 2 showed a higher complication rate of 36.59% compared to group 1 (20.34%). Significant complications noted were secondary glaucoma (8%), disenclavation of haptic (4%), subluxation of RFIC lens (1%).

Conclusion:

The visual outcome with RFIC lenses when combined with other intraocular procedures is mainly affected by the complexity of co-existing pathologies .The complications are more related to the combined procedures performed rather than RFIC lens implantation alone. This may still be acceptable when complication profile of other intraocular lenses is evaluated in similar challenging situations.

Visual Outcomes after Primary Iris Claw Artisan Intraocular Lens Implantation during Complicated Cataract Surgery

PURPOSE

To evaluate the efficacy and safety of aphakic Artisan-Verysise intraocular lens (IOL) primarily implanted for complicated cataract surgery.

METHODS

A retrospective analysis of 49 eyes that underwent primary aphakic Artisan IOL implantation for complicated cataract surgery. Pre- and postoperative uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and spherical equivalents (SE) were compared.

RESULTS

The mean age of the participants was 68 ± 12.7 years, and the mean follow-up time was 30.7 ± 14.8 months. The mean BCVA improved significantly from 0.58 ± 0.4 at baseline to 0.44 ± 0.41 after the operation (P = 0.008). The spherical equivalent changed insignificantly from -0.13 ± 1.55 preoperatively to -0.6 ± 1.88 (P = 0.724) at the last visit. Postoperative complications were transient pigmented precipitates in five cases and raised intraocular pressure in one case.

CONCLUSION

Aphakic Artisan IOLs are attractive alternatives in complicated cataract surgery without sufficient capsular bag support.

Two-Year Follow-Up of Artisan Iris-Supported Phakic Anterior Chamber Intraocular Lens for Correction of High Myopia

PURPOSE

To evaluate the results of Artisan iris-supported phakic anterior chamber intraocular lens (pIOL) implantation in patients with high myopia.

METHODS

Medical records of patients who underwent Artisan pIOL implantation for surgical correction of myopia were retrospectively reviewed. Only patients with at least a two- year follow-up were included. Spherical equivalent of manifest refractive error (SE), uncorrected visual acuity (UDVA), distance corrected visual acuity (CDVA), and endothelial cell density (ECD) were analyzed at six months, one year, and two years after surgery.

RESULTS

Sixty-two eyes of 42 patients were included in the study. All patients had a minimum anterior chamber depth of 3.0 mm from the endothelium. At two years, 68% of the patients were within ±0.50 D. Mean ECD was 2723 ± 311 cells/mm(2) preoperatively and 2630 ± 291 cells/mm(2) at six months postoperatively (3.4% loss, p = 0.001). ECD loss from six months postoperatively to two years postoperatively was not statistically significantly different. In three eyes (4.8%) of two patients, a temporary, steroid-induced increase in intraocular pressure (IOP) was detected.

CONCLUSION

Artisan pIOL implantation is a safe and highly effective procedure for surgical correction of high myopia. ECD loss stabilizes in the early postoperative period.

Aphakia correction with retropupillary fixated iris-claw lens (Artisan) - long-term results

PURPOSE

To evaluate the technique, safety, and efficacy of the retropupillary implantation of iris-claw intraocular lenses in a long-term follow-up study.

PATIENTS AND METHODS

This retrospective study included 31 eyes of 31 patients who underwent an Artisan aphakic intraocular lens implantation between January 2006 and February 2011 at the University Hospital Essen, Essen, Germany and at the Zentrum für Augenheilkunde PD Dr Laube, Düsseldorf, Germany. Preoperative data collected included demographics, etiology of aphakia, previous surgeries, preoperative eye pathology, intraocular pressure, clinical signs of endothelial cell loss, and best corrected visual acuity. Operative data and postoperative outcomes included the best corrected visual acuity, lens position, intraocular pressure, pigment dispersion, clinical signs of endothelial cell loss, development of macular edema, and other complications.

RESULTS

Thirty-one patients were included. The mean follow-up was 25.2 months (range: 4-48 months). The mean best corrected visual acuity postoperatively was 0.64 logarithm of the minimum angle of resolution (logMAR) and varied from 0 logMAR to 3 logMAR. Some patients had a low visual acuity preoperatively because of preoperative eye pathologies. In 22 patients the visual acuity improved, in two patients the visual acuity remained unchanged, and seven patients showed a decreased visual acuity. Complications were peaked pupils (n=10) and retinal detachment in one case. Four patients showed an iris atrophy and high intraocular pressure was observed only in one patient. Subluxation of the intraocular lens, endothelial cell loss, and macular edema were not observed.

CONCLUSION

The presented long-term results demonstrate that retropupillary iris-claw lens implantation is a safe and effective method for the correction of aphakia in patients without capsule support. This surgical procedure has the advantages of a posterior chamber implantation with a low intraoperative and postoperative risk profile.

Implantation of iris-claw Artisan intraocular lens for aphakia in Fuchs' heterochromic iridocyclitis

Implantation of iris-claw Artisan intraocular lens (IOL) is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs’ heterochromic iridocyclitis (FHI) due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphakia with no capsular support due to a previous complicated cataract surgery. Enclavation was easily performed and no intraoperative complication was noted. Postoperative course was uneventful with no significant anterior chamber inflammation during 12 months of follow-up. Although there were few deposits on the IOL surface, the patient achieved a best-corrected visual acuity of 20/20 without developing glaucoma or other complications. Therefore, Artisan IOL may be considered for correction of aphakia in patients with FHI. However, studies on large number of patients are required to evaluate safety of the procedure.

Spontaneous subluxation of iris-claw aphakic intraocular lens causing complications in two children

Many surgeons consider implantation of iris-claw intraocular lenses a favorable option for pediatric aphakic eyes with poor capsular support. The authors present two children who had spontaneous subluxation of such lenses resulting in complications that required explantation. These cases highlight the potential sight-threatening complications of such intraocular lenses.

Comparative evaluation of suture-assisted and fibrin glue-assisted scleral fixated intraocular lens implantation

PURPOSE

To compare the visual outcomes and complications after suture-assisted and fibrin glue-assisted scleral fixated intraocular (IOL) implantation.

METHODS

Scleral fixated IOL implantation was performed in patients with inadequate capsular support. Intraocular lens fixation was achieved using sutures or fibrin glue. Main parameters evaluated were visual outcomes and complications.

RESULTS

Fifty patients were included in the study (n=25 suture, n=25 glue). The most common indication for scleral fixated IOL implantation was cataract surgery complicated with posterior capsule rupture (29/50 [58%]). No significant differences were noted between demographic characteristics, surgical indications, and preoperative corrected distance visual acuity (CDVA) in either group (P=.680). No intraoperative complications related to IOL fixation were encountered in any case. At last follow-up (6 months), CDVA was 20/40 or better in 88% and 84% of patients in the suture and glue groups, respectively. Postoperative inflammation (48% vs 16%) and glaucoma (40% vs 16%) were seen more frequently in eyes with sutures as compared to eyes with glue. Overall, a significantly higher number of complications were encountered in eyes with suture fixation (14/25 [56%]) compared to eyes with glue fixation (7/25 [28%]) (P=.045).

CONCLUSIONS

Although visual outcomes were similar at the end of 6 months in eyes that underwent suture- and glue-assisted scleral fixated IOL implantation, fibrin glue was associated with fewer complications.
