Postoperative Vitreous Hemorrhage

Purpose. To evaluate the short-term postoperative outcomes in endoscopic-assisted sclera fixation intraocular lens (IOL) for the management of secondary aphakia in children.Methods. This is a prospective study, whereas 40 aphakic eyes with absence of a good capsular support were implanted by endoscopy-assisted sclera fixation technique.Results. No major intraoperative complications were recorded. All cases were followed up for 6 months. Only transient ocular hypertension occurred in 10 (25%) eyes. Lens decentration and/or tilting were clinically detected in 2 eyes (5%). Ultrasonic biomicroscopic (UBM) examination revealed lens tilting in 2 (5%) of the operated eyes, despite the proper haptics positioning in the ciliary sulcus. Postoperative vitreous hemorrhage was reported in 5 eyes (12.5%) in the early postoperative period and retinal detachment in one eye. A postoperative refractive astigmatism ranging from 0.75 D to 3.75 D (mean 1.7 D ± 0.79) was recorded, as compared to mean preoperative values of 2.00 D, with no statistically significant differences being recorded (p≥0.05). An improvement of BCVA, 1-2 lines on Snellen chart at the end of the follow-up period, was detected in 23 eyes (57.5%) with a mean of0.6±0.08 SD, as compared to a preoperative mean values of0.5±0.07 SD (p≥0.05).Conclusion. Using an endoscope for transscleral suturing of intraocular lenses in aphakic pediatric eyes might be considered as being an effective technique that can reduce surgical complications, especially postoperative lens decentration.

A Prospective Study

Purpose Viscocanalostomy is a new, non-penetrating procedure for glaucoma surgery. We started a prospective study to assess the effectiveness and safety of the operation. Materials and methods Up to March 1998 we enrolled 33 patients (33 eyes) suffering from glaucoma, uncontrolled despite maximum medical therapy, who underwent viscocanalostomy according to Stegmann's technique. A complete ophthalmological examination was performed the day before surgery and on days 1 and 7 postoperatively. Further visits were scheduled at months 1, 3, 6 and 12. Results In four eyes Schlemm's canal was either missed or not deroofed properly, and the procedure was converted into simple trabeculectomy. After a mean follow-up of 3.0±2.6 months (range 1–10), success defined as IOP > 2 and < 21 mmHg with no medication was obtained in 86.2% of the cases (25/29); 23 out of 29 eyes (79.3%) had IOP > 2 and < 16 mmHg. In the 25 successful eyes, mean IOP was 27.7±9.5 mmHg (range 13–48) preoperatively and 12.0±3.0 mmHg (range 7–18) (p<0.0001) at the end of the follow-up period. Mean VA ranged from 0.35±0.34 to 0.32±0.32 (n.s.). Intraoperative complications included Descemet rupture (7), with iris plugging in two cases; choroidal deroofing (3), irregular incision of Schlemm's canal (2). Postoperative complications included: self-resolving 2-mm hyphema (4); IOP spike (1); inadvertent filtering bleb (2); hypotony with choroidal detachment for one week (1). Conclusions In this short-term study, viscocanalostomy proved effective and safe in lowering IOP in glaucomatous eyes.

Purpose. To report a new technique for sutureless intrascleral fixation of three-piece foldable intraocular lenses (IOLs) using 25-gauge trocars. Methods. We performed this technique on patients with insufficient posterior capsule support. Seventeen eyes from 15 patients with aphakia, dislocated IOL, or subluxated crystalline lens undergoing posterior chamber sutureless implantation of an IOL were studied. The haptics of the IOL were externalized using two 25-gauge forceps. The haptics were bended back (hook-like) into the vitreous cavity through a scleral incision made by using a 25-gauge trocar. And, IOL tilt was determined by using a slit lamp and UBM, and complications were recorded. Results. The IOLs were fixed with exact centration and axial stability. No wound leakage was reported even without the use of sutures. The mean best-corrected visual acuity (BCVA) was 0.82 logarithm of the minimum angle of resolution (logMAR) units preoperatively, and the mean BCVA was 0.44 logMAR units at the 6-month follow-up visit. No postoperative retinal detachment, endophthalmitis, IOL tilt or dislocation, or vitreous hemorrhage was noted. Conclusion. Sutureless intrascleral haptic-hook posterior chamber IOL implantation using 25-gauge trocars provides good IOL fixation with reliable wound closure without the use of sutures. This trial is registered with ChiCTR1800017436.

Purpose: To analyse the outcomes of sutureless and sutured scleral fixated intraocular lenses (SFIOL) in paediatric population. Setting: Vitreoretina department of a tertiary eye care institute in Southern India Design: Retrospective case series Methods: Data were collected from January 2010 to December 2018 for children less than 18 years of age, based on the following parameters: demographics, pre-operative characteristics, duration between aphakia and surgery, previous amblyopia treatment, the uncorrected (UCVA) and the best corrected visual acuity (BCVA) at baseline and, 1,6 and 12 months or final visit. Early and late post-operative complications along with details of any resurgery was recorded. Results: The study included 45 eyes of 43 patients. The mean age when children became aphakic was 8.8±3.6 years and the mean age at SFIOL implantation 10.1 ± 3.9 years. Sutureless SFIOL was performed for 36 (80%) eyes. The improvement in UCVA was statistically significant at 1-month follow up. Transient hypotony (n = 3), vitreous hemorrhage ( n = 7) and raised IOP ( n = 4) were the most observed early post-operative complications, while haptic exposure or disinsertion ( n = 4, 9%) was a delayed postoperative complication. The mean spherical equivalent at the last follow up was 1.96 ± 0.83D and mean postoperative cylinder 2.32 ± 1.3D. The children were followed up for a mean duration of 20 ± 21.7 months. History of previous vitrectomy was found to be associated with two line reduction in UCVA (95% CI = 0.03–0.5 logMAR, p = 0.008). Conclusion: SFIOLs- sutured and sutureless; both were suitable for the rehabilitation of paediatric aphakia. Sutureless scleral fixation is a safe alternative for children but prospective studies with longer follow-up are needed.

Background. With the advances in surgical tools, simultaneous removal of cataract associated with vitreoretinal disorders is gaining popularity. This combined surgery offers several advantages besides limitations. The aim of this study is to assess the outcome and complications of phacoemulsification combined with pars plana vitrectomy (PPV). Patients and Methods. In this retrospective review, medical charts of patients undergoing phacovitrectomy for coexisting cataract and various vitreoretinal disorders were analyzed. Patient demographics, retinal diagnosis, visual acuities (VA) in logMAR, intraocular pressure (IOP), intraoperative and postoperative complications were assessed. Clear corneal phacoemulsification and 23-gauge transconjunctival PPV were administered in all cases. Results. Eighty-four eyes of 64 (76.2%) males and 20 (23.8%) females were enrolled. The average age of patients was 59.5 ± 13.8 (18–81). The average period of follow-up was 7.2 ± 7.5 months (1–36). The vitreoretinal diagnoses were as follows: 28 (33.3%) rhegmatogenous retinal detachment, 23 (27.4%) vitreous hemorrhage, 12 (14.3%) intraocular foreign body, 12 (14.3%) epiretinal membrane, 4 (4.8%) macular hole, 4 (4.8%) tractional retinal detachment, and 1 (1.2%) vitreomacular traction. The most common intraoperative complications were miosis and rupture of the posterior capsule (92.9% and 8.3%, respectively). In 8 (9.5%) cases, there was fibrin in the anterior chamber. Posterior synechia developed in 7 (8.3%) of cases. No severe increase in intraocular pressure was evident. Conclusion. Phacoemulsification combined with PPV is a safe and efficient way of management in cases where cataract coexists with vitreoretinal pathologies.

Purpose: The purpose of this article is to examine the clinical outcomes of scleral fixation of intraocular lenses (IOLs) using Gore-Tex suture at our institution. Methods: A retrospective chart review was conducted of patients who underwent scleral fixation of an IOL with Gore-Tex suture with concurrent pars plana vitrectomy. Intraoperative and postoperative complications were assessed. Results: Seventy-four eyes of 74 patients were included with a mean follow-up interval of 210 days (range, 33–720 days). The mean best-corrected visual acuity improved from 20/480 (1.38 logarithm of the minimum angle of resolution [logMAR]) preoperatively to 20/78 (0.59 logMAR) postoperatively ( P < .001). Indications included dislocated lens implant (42), aphakia without capsular support (18), and subluxation of crystalline lens (14). Bausch and Lomb Akreos AO60 IOL was implanted in 52 eyes, Alcon CZ70BD in 15, and Bausch and Lomb enVista MX60 in 6. Postoperative complications included temporary ocular hypertension in 9 eyes (12%), temporary hypotony in 7 (9%), cystoid macular edema in 3 eyes (4%), corneal decompensation in 2 eyes (3%), IOL dislocation requiring exchange in 1 case (1.4%), vitreous hemorrhage in 2 cases (3%), and retinal detachment in 2 cases (3%). There were no cases of postoperative suture breakage or erosion, endophthalmitis, or hyphema. Conclusions: The use of Gore-Tex suture in scleral fixation of posterior chamber IOLs was well tolerated at a mean follow-up interval of 210 days. There were no suture-related complications.

Anchoring Technique

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.

This was a prospective study to evaluate the feasibility of the photic phenomena test (PPT) for quantifying glare, halo, and starburst. We compared two presbyopia-correcting intraocular lenses (IOLs), the Symfony IOL and the PanOptix IOL, as well as the monofocal Clareon IOL in 111 IOL-implanted eyes of 111 patients who underwent the PPT 1 month postoperatively. The reproducibility of photic phenomena with the PPT was assessed in 39 multifocal IOL-implanted eyes of 20 patients and among the examiners. Patients with ocular diseases, except for refractive errors, were excluded. The mean values of the groups were evaluated. Bland–Altman plots were used to analyze statistical data (Easy R version 1.37; R Foundation for Statistical Computing, Vienna, Austria). The PPT reproducibility assessment revealed no fixed bias or regressive significance. Reproducibility was confirmed. The glare size did not differ significantly between the Symfony, PanOptix, and Clareon groups. The halo size was significantly larger in the Symfony group (p < 0.01) than in the PanOptix group. The halo intensity was significantly brighter in the PanOptix group (p < 0.01) than in the Symfony group. In contrast, no halos were perceived in the Clareon group. The starburst size or intensity did not differ significantly between the Symfony, PanOptix, and Clareon groups. We identified the photic phenomenon related to various IOLs.

Introduction Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Several methods have been proposed for repairing a distal penile erosion. We present our preliminary experience in “Distal corporoplasty” technique. Methods We enrolled 18 consecutive patients whose underwent a distal corporoplasty with simultaneous reimplantation of an “AMS 700 inflatable penile prosthesis (LGX)” from January 2013 to November 2015 at our hospital. All procedures were performed by a single surgical team. Intraoperative and postoperative complications have been classified and reported according to Satava6 and Clavien-Dindo (CD) system.7 Mean values with standard deviations (±SD) were computed and reported for all items. Results Mean age of the patients was 53.61 (±11.90) years. Mean body max index (BMI) was 24.22 (±2.51). Mean operative time was 85.2 (±13.1) minutes. Blood losses were minimal. No intraoperative complications are reported according to Satava classification. Four out of 18 patients (22.22%) experienced postoperative complications according to CD system. All patients had sexual intercourse for the first time postsurgery after a mean of 59.11 ± 2.08 days. Mean follow-up was 22.11 (±9.95). Discussions Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Distal corporoplasty was first described by Mulcahy. He reported a series of 14 patients with a follow-up of about 2 years with optimal functional outcomes. Moreover, distal corporoplasty resulted in shorter operative time, better function, less pain, and fewer recurrences than Gortex windsock repair.10 In our experience, distal corporoplasty is a simple and safe procedure in the treatment of distal cylinders extrusion when the prosthetic material is not exposed to the exterior.

New Surgical Technique

Bipolar diathermy scissors tonsillectomy is a relatively new surgical technique. We conducted a prospective study of 90 patients to compare this technique with bipolar forceps tonsillectomy. We found that the use of the bipolar scissors required significantly less operating time (mean: 3.03 min less) and allowed patients to resume eating solid food more rapidly (mean: 40.35 min earlier). Bipolar scissors tonsillectomy was safe, and there were no intraoperative complications or primary hemorrhages. A postoperative follow-up telephone survey revealed that patients who underwent scissors tonsillectomy experienced no more morbidity than did the forceps group during the first 2 weeks after surgery. We conclude that bipolar scissors tonsillectomy is a safe and rapid technique that can be used successfully as an outpatient procedure.

Abstract PurposeTo report a technique for fixating posterior chamber intraocular lenses (PCIOLs) to the sclera by passing sutures through the lens materialMethodsCases in which PCIOLs were fixated to the sclera using trans-optic sutures were included in this series. Intra and post-operative complications were recorded, and lens position was assessed using slit lamp examination.ResultsFourteen cases were included in this series. In 9 cases the procedure was performed using 9-0 polypropylene in pseudophakic eyes to correct subluxation, centration, tilt or to replace a broken haptic. In 5 cases this technique was used for primary PCIOL fixation using a flanged 6-0 polypropylene suture in aphakic eyes. In all cases the lenses remained centered and stable at the end of follow up, and no post-operative complications occurred.ConclusionTrans-optic suturing is a safe and effective alternative method for fixation of IOLs in a variety of pseudophakic and aphakic clinical scenarios.
