Posterior Chamber Intraocular Lens

Purpose. To evaluate the short-term safety and efficacy of a novel approach of utilizing the 9-0 looped polypropylene suture with double knots buried into the scleral groove and the scleral tunnel to minimize the risk of the suture erosion and suture knot exposure. Design. Clinical-based retrospective study. Methods. Records of consecutive patients who had anterior vitrectomy and scleral-fixated posterior chamber intraocular lens (IOL) implantation between July 2018 and April 2020 with a minimum follow-up of 3 months were reviewed. Results. This study enrolled a total of 21 eyes from 20 patients (15 male). These patients had a mean age of 58.52 ± 8.55 years and were followed for an average of 1.08 ± 0.58 years postoperatively. Best-corrected visual acuity (BCVA) improved from a preoperative mean of 0.43 ± 0.41 logMAR to a significantly higher mean 3-month postoperative value of 0.09 ± 0.21 logMAR (Z = -3.35, p < 0.01 ). There were no statistical differences between the preoperative and postoperative corneal endothelial cell density ( p = 0.71 ). The postoperative complications included transient increased intraocular pressure in 5 eyes (24%). No other complications were detected during the follow-up. Conclusions. The modified technique proposed is a safe, effective, and reliable approach resulting in good visual outcomes. Our procedure might have the potential benefit to avoid suture-related complications in scleral-fixated IOL implantation. Trial registration. Retrospective case series study, not applicable.

The aim of this article is to report the results of an innovative technique for a scleral fixation of a posterior chamber intraocular lens using our new modified technique. We retrospectively reviewed the medical records of 15 eyes of 15 patients who underwent sutureless intrascleral intraocular lens fixation using our modified technique. We used a 23-gauge knife to perform sclerotomy and create two parallel scleral pockets for the haptics. The mean follow-up period was 3 years (3 ± 1). No complications were detected during the follow-up period. The creation of two parallel scleral pockets, parallel to the limbus, greatly simplifies the introduction of intraocular lens haptics.

Purpose. To evaluate surgical efficacy of in situ refixation technique for dislocated posterior chamber intraocular lens (PCIOL).Methods. This was a single-center retrospective case series. 34 patients (34 eyes) who underwent sclera fixation for dislocated IOLs combined with vitrectomy were studied. Of 34 eyes, 17 eyes underwent IOL exchange and the other 17 eyes underwent in situ refixation.Results. Mean follow-up period was 6 months. Mean logMAR best corrected visual acuity (BCVA) was not significantly different between the groups 6 months after surgery (0.10±0.03in the IOL exchange group and0.10±0.05in the refixation group;p=0.065). Surgically induced astigmatism (SIA) was significantly lower in the refixation group (0.79±0.41) than in the IOL exchange group (1.29±0.46) (p=0.004) at 3 months, which persisted to 6 months (1.13±0.18in the IOL exchange group and0.74±0.11in the refixation group;p=0.006). Postoperative complications occurred in 3 eyes in the IOL exchange group (17.6%) and 2 eyes in the refixation group (11.8%). However, all of the patients were well managed without additional surgery.Conclusion. The in situ refixation technique should be preferentially considered if surgery is indicated since it seemed to produce a sustained less SIA compared to IOL exchange.

Purpose: To report a new technique using tram-track suture for pupillary capture of a scleral fixated posterior chamber intraocular lens (PC-IOL) to reposition the tilted IOL. Methods: In this prospective interventional case series, we describe a tram-track suture for pupillary capture of a scleral fixated PC-IOL. A long straight needle with double-armed 10-0 polypropylene is passed behind the iris and just above the optic portion (tilted forward) of the IOL. The other straight needle with double-armed 10-0 polypropylene is passed just below the optic portion (tilted backward) of the IOL. After the IOL is repositioned properly, the polypropylene sutures are gently pulled and tied. Results: Four eyes of 4 patients underwent tram-track suture for pupillary capture of a scleral fixated PC-IOL. No intra- or postoperative complications were noted, and no pupillary captures were detected during the follow-up period. Conclusions: The tram-track suture technique provides good centration and stability of a PC-IOL. This technique is an easy and effective way to reposition pupillary capture of an IOL. Further, it is also minimally invasive as it maintains a closed system.

Abstract Background To report a new technique for iris capture of the posterior chamber intraocular lens (IOL) implanted in patients with a posterior capsule defect. Methods In this retrospective case series, a rectangular loop ciliary body suture technique was performed to rectify iris capture. The suture passes between the IOL and iris in a direction perpendicular to the iris edge capturing the IOL. Results A total of three IOLs with iris capture underwent a rectangular loop suture technique. No recapture was observed postoperatively. In one case, large astigmatism appeared after the surgery but recovered at 1 month post operation. No further complications were found. Conclusions The rectangular loop suture technique is an effective, convenient, and minimally invasive method for iris capture of the IOL.

Purpose: We report the longest follow-up to our knowledge of stable scleral fixation of a posterior chamber intraocular lens (PC IOL) with 10-0 polypropylene sutures. Methods: A retrospective review is presented of a case with more than 30 years’ follow-up after performing sutured scleral fixation with 10-0 polypropylene suture using 2 sutures tied together under a scleral flap. One suture was a cow-hitch looped around the haptic, and the other suture was passed through the sclera to create the scleral fixation. Results: The scleral fixation with 10-0 polypropylene suture knots for both haptics of the PC IOL allowed central optic positioning with excellent vision for more than 30 years without suture breakage. Conclusions: Polypropylene sutures for scleral fixation of PC IOLs remained stable for more than 30 years with central positioning of the PC IOL, without exposure of the fixation suture knots through the conjunctiva, and without suture breakage.

Abstract Background Alemtuzumab is an effective disease-modifying therapy (DMT) for highly active multiple sclerosis (MS). However, safety concerns limit its use in clinical practice. Objectives To evaluate the safety of alemtuzumab in a nationwide cohort of Finnish MS patients. Methods In this retrospective case series study, we analyzed the data of all but two MS patients who had received alemtuzumab in Finland until 2019. Data were systematically collected from patient files. Results Altogether 121 patients were identified, most of whom had received previous DMTs (82.6%). Median follow-up time after treatment initiation was 30.3 months and exceeded 24 months in 78 patients. Infusion-associated reactions (IARs) were observed in 84.3%, 57.3%, and 57.1% of patients during alemtuzumab courses 1–3, respectively. Serious adverse events (SAEs) were observed in 32.2% of patients, serious IARs in 12.4% of patients, and SAEs other than IARs in 23.1% of patients. Autoimmune adverse events were observed in 30.6% of patients. One patient died of hemophagocytic lymphohistiocytosis, and one patient died of pneumonia. A previously unreported case of thrombotic thrombocytopenic purpura was documented. Conclusions SAEs were more frequent in the present cohort than in previous studies. Even though alemtuzumab is a highly effective therapy for MS, vigorous monitoring with a long enough follow-up time is advised.

Objectives: Penile fracture with concomitant complete urethral disruption is an uncommon urologic disorder. Data about the treatment and outcome measurements of this condition are scarce in the literature. The aim of the present study is to evaluate the long term urinary and sexual functions of patients with penile fracture associated with complete urethral injury after immediate surgical reconstruction. Patients and methods: Twelve patients met our inclusion criteria and were included in this retrospective case series study; however, one was lost during follow-up. Patient's medical records were reviewed and all patients were interviewed for clinical evaluation. Urinary function was assessed by history, uroflometry and retrograde urethrography, while, sexual function was assessed by questionnaire (Sexual Health Inventory for Men) and penile Doppler for patients with erectile dysfunction. Results: Patients’ mean age was 32.3 ± 7.5 years (range 21-43) and the mean follow-up period was 72.6 ± 45.4 months (range 14-187). Vigorous sexual intercourse was the main cause in 91% of our patients. No serious long term complications was found. Only 1 patient (9%) suffered from anterior urethral stricture, 1 patient (9%) complained of weak erection, 3 patients (27%) had a palpable fibrosis and 2 patients (18%) reported a slight penile curvature during erection. Ninety one percent of all our patients maintained their normal urinary and sexual functions. Conclusion: On the long term follow-up, most of the patients maintained their normal erectile and voiding functions with no harmful long-term complications. We advocate immediate surgical intervention and reconstruction of both corpora cavernous and urethra as a first line treatment for those patients.

Purpose: To assess the indications and visual outcome of eyes undergoing posterior iris fixated intraocular lens (IFIOL) implantation for aphakia, to identify reasons for poor visual outcome, and report occurrence of complications. Methods: In this retrospective case series study, all cases of posterior IFIOL fixation performed over a 30-month period were identified retrospectively. Preoperative and postoperative evaluations comprised objective and subjective refraction, best corrected visual acuity (BCVA), slit lamp biomicroscopy, applanation tonometry, and dilated fundus examination. Results: Fifty-six eyes of 56 patients were analyzed. Mean age was 60.55 ± 17.2 years. The most common indication for IFIOL implantation was surgical aphakia following complicated cataract surgery (n = 33; 58.9%) followed by trauma (n = 10; 17.9%), dropped nucleus/IOL during primary surgery (n = 6; 10.7%), and subluxated/dislocated lens-induced glaucomas (n = 5; 8.9%). BCVA better than or equal to their preoperative BCVA was achieved in 96.43% patients. The surgical aphakia and paediatric/adolescent groups had the best visual results while the dropped nucleus/IOL group and subluxated lens-induced glaucoma groups fared poorly. On the long-term follow-up visit, the most common complication noted was pigment dusting on the corneal endothelium (65.7%). Conclusion: The long-term results suggest that posterior IFIOL implantation is a safe and effective method for correction of aphakia and can be used for a wide range of indications in eyes without adequate capsule support. It may be considered an easier and faster alternative with minimal manipulation to anterior segment structures in paediatric and post-traumatic aphakic eyes.
