Purpose. Siderosis bulbi may occur as a result of retained intralenticular foreign bodies (ILFBs) that were missed during examination in patients with self-sealing wounds and without a significant decrease in visual acuity. This study aimed to explore the clinical characteristics and visual outcomes of ILFBs with self-sealing corneal penetrating wounds. Methods. Fifteen eyes of 15 patients with ILFBs and self-sealing corneal penetrating wounds, seen between October 2014 and September 2019, were retrospectively analyzed. Data regarding the patient demographics, clinical features, surgical procedure, and initial and final best-corrected visual acuity (BCVA) were analyzed. Results. All patients were male with a mean age of 41 years. The foreign bodies passed through the cornea, sometimes through the iris, through the anterior capsule, and finally localized in the lens. All ILFBs were pointed and metallic objects and were successfully removed with phacoemulsification and posterior chamber intraocular lens (IOL) implantation. Anterior capsule violation was found in three eyes, but no posterior capsule rupture was found. The IOL was placed in a capsule bag in all the cases. The BCVA ranged from 20/200 to 20/25 preoperatively and improved to between 20/32 and 20/20 at the last follow-up visit. The IOLs were well-centered. Apart from posterior capsule opacity in four eyes, no other postoperative complications were found. Conclusions. In patients with a pointed metallic ILFB and self-sealing corneal penetrating wounds (with or without cataracts), early diagnosis and removal of the metallic ILFB combined with lens removal and IOL implantation may avoid late complications and achieve good visual outcomes.

Introduction: Intraocular foreign bodies (IOFBs) are a serious subset of open-globe injury that can result in visual loss. This study analyzed the epidemiology, clinical characteristics and visual outcomes of patients with IOFBs in Southwest China. Methods: This retrospective study comprised 1176 patients with the primary diagnosis of IOFBs who resided in Sichuan Province over a 10-year period. All data were collected from medical records and analyzed statistically. Results: The annual incidence for IOFBs was 0.14 per 100,000 (95% CI 0.12–0.16 per 100,000) people in Southwest China. In that period, IOFBs accounted for 22.3% of all open-globe injuries. Working-age male patients accounted for 79.1% of all IOFBs patients and there had significant differences in age distributions between genders(P<0.001). Metallic IOFBs was the most common (74.6%) IOFB, but there were significant differences in the materials of IOFBs between adults and children of different age groups (P<0.001). At discharge, 277 (23.6%) patients had increased visual acuity (VA) and 95 (8.0%) had no light perception. Initial visual acuity (VA) < 20/200 (OR, 5.5; P<0.001), increasing wound size (OR, 1.3; P=0.004), IOFBs in the posterior segment (OR, 2.6; P=0.002) and existing complications (traumatic cataract, endophthalmitis, retinal detachment or retinal break) were independent risk factors for final VA < 20/200. Conclusion: The incidence of IOFBs in Southwest China differed from global statistics. Adults and children had different clinical characteristics. Thus, their prevention strategies should be different.

Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

Aim. To describe epidemiologic and clinical characteristics and prognostic factors influencing visual outcome after intraocular foreign bodies (IOFBs) injury. Methods. Medical records of 370 patients (373 eyes) with IOFBs were reviewed to identify the factors influencing visual acuity by univariate and multivariate analyses. Results. The majority of patients (97.0%) were men, with a mean age of 38.1 years. The most common cause of ocular injury was hammering (52.6%); magnetic IOFBs occurred in 84.7% of these cases. Factors associated with poor visual outcome (defined as <1.3 logMAR) included the following: age ≥50 years (P=0.046); worse presenting visual acuity (P<0.001); complications of retinal breaks (P=0.006) and endophthalmitis (P=0.032); vitrectomy (P=0.035); and intraocular C3F8 gas tamponade (P=0.038). Excellent visual outcome (defined as ≥0.5 logMAR) was associated with age <50 years (P=0.003); better presenting visual acuity (PVA) (P<0.001); wound length <4 mm (P=0.005); absence of vitreous hemorrhage (P=0.026) and retinal breaks (P<0.001); nonvitrectomy surgery (P=0.043); and use of balanced saline (P=0.029). Conclusions. Multiple prognostic factors were identified that may predict visual outcome and globe survival after IOFBs injury. Age, initial presenting visual acuity, wound length, complications (vitreous hemorrhage, retinal breaks, and endophthalmitis), surgical approach, and intraocular tamponade were significant predictors of visual outcome.

Objective. To investigate the clinical characteristics and factors affecting visual outcome in patients with intraocular foreign bodies (IOFBs) and determine the risk factors for the development of endophthalmitis. Study Design. A retrospective case-series study design was adopted. Subjects. In total, 242 patients (242 eyes) who were hospitalized and underwent surgical treatment for IOFB at the Second Hospital of Hebei Medical University between January 1, 2008, and December 31, 2019, were included. Methods. The demographic data, cause of injury, characteristics of IOFBs, postinjury ocular manifestations, and surgical details of the subjects were collected, and the factors affecting visual outcome and endophthalmitis development were analyzed. Results. The most common cause of IOFBs was the propulsion of foreign bodies into the eye due to hammering (149 cases, 61.57%), followed by foreign body penetration (57 cases, 23.55%). Most of the subjects were young adult men who sustained injuries in the work environment. Poorer visual outcomes were found in subjects with initial presenting symptoms visual acuity (PVA) < 0.1, largest IOFB diameter ≥ 3 mm, IOFBs located in the posterior segment, wound length > 5 mm, entrance wound length larger than the largest IOFB diameter, concomitant retinal detachment, concomitant vitreous hemorrhage, concomitant endophthalmitis, and concomitant proliferative vitreoretinopathy (PVR). Factors related to the development of endophthalmitis included lens capsule rupture, time of stage 1 repair surgery ≥ 24 h after trauma, removal of IOFBs ≥ 24 h after trauma, and nonadministration of intravitreal antibiotic injection. Conclusion. Among patients with IOFBs, initial PVA < 0.1, entrance wound length larger than the largest IOFB diameter, concomitant endophthalmitis, and concomitant PVR were risk factors for poor visual outcomes. Lens capsule rupture was a risk factor for endophthalmitis development, and the administration of intravitreal antibiotic injection was a protective factor against endophthalmitis development.

Objectives: To compare visual outcomes, principally myopic shift, visual acuity, intraocular pressure and strabismus between primary and secondary intraocular lens (IOL) implantation following congenital cataract surgery. Methods: A retrospective study of the long-term ocular outcomes in primary versus secondary IOL implantation (IOL-I) following congenital cataract surgery was conducted. We analyzed the files of all children with congenital cataract who underwent unilateral or bilateral lensectomy, posterior capsulotomy and anterior vitrectomy followed by primary or secondary IOL-I between 2000 to 2012, at King Abdulaziz University Hospital, Jeddah. Preoperative and postoperative assessment of each operated eye in terms of axial length, refractive errors, strabismus as well as (post IOL-I) intraocular pressure (IOP) and best corrected visual acuity (BC-VA) were collected and analyzed. Results: Data of 26 eyes of 14 patients (9 males, 6 females) was analyzed: 16 (61.5%) eyes underwent lensectomty and anterior vasectomy with primary IOL-I and 10 (38.5%) eyes underwent lumpectomy and anterior vasectomy with secondary IOL-I. Mean age at cataract surgery was 67.53 (± 48.70) months in the group of primary IOL-I versus 5.90 (± 3.72) months in the group of secondary IOL-I; and patients were followed up for 49.33 (± 26.23) versus 86.50 (± 23.36) months, respectively (p=.051). In the secondary IOL-I group, the mean of time from primary lensectomy to IOL-I was 50.44 (± 18.41) months. Last BC-VA showed better outcomes in primary IOL-I group as 10 eyes (83.3%) with good VA versus only 2 eyes (20%) in the secondary IOL-I, (p=0.009). Myopic shift was greater in secondary IOL group 10.86 (± 11.62) versus 0.19 (± 2.38) diopters (D) in primary IOL (p=0.046*); while no significant difference was observed in IOP (p=0.697). No case of isotropic was detected in primary versus 6 cases in the secondary IOL group. Conclusion: Visual outcomes, including visual acuity, strabismus and myopic shift were better in the group of children who underwent primary IOL implantation at age of >2 years, when compared to those with secondary IOL implantation at the age of <2 years, following congenital cataract surgery. However, poor visual acuity in the secondary IOL group was mainly explained by the relatively higher prevalence of eye complications in this group.

Intraocular foreign bodies (FBs) are common ocular injuries reporting to the emergency services all over the world. The authors highlight the findings and surgical management of a case of intralenticular metallic FB following an injury while using chisel and hammer. The ocular path of the FB (2 mm) could be traced from a self-sealed corneal perforation, extending through the anterior capsule rupture, terminating at the posterior capsule, forming a posterior capsule tent with a part embedded in clear lens. Preoperative ultrasound biomicroscopy gave clues on posterior capsule integrity and the exact site of FB, and helped prognosticate and plan the surgical management of the case. The ‘locked-in’ FB was extracted after clear lens aspiration and posterior capsulorrhexis. The posterior capsule acted as a natural barrier between anterior and posterior segment, where the FB was found embedded.

Aim: To assess the complications and visual outcomes associated with cataract surgery in camp patients operated at a tertiary centre. Materials and methods: In a retrospective study, 206 outreach camp patients had undergone cataract surgeries with posterior chamber intraocular lens implantation under peribulbar anesthesia over a period of 6 months. Post-operative complications on Day 1 were graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions. One month postoperative complications, best corrected visual acuity and refractive errors were assessed. Results: 206 eyes underwent cataract extraction with PCIOL implantation. Small incision cataract surgery (SICS) was the commonest method (78.6%) used. The most common first post-operative day complication was mild iridocyclitis (26.2%). The complications were based on OCTET definitions, and showed that 33 % had Grade I and 3.4 % had Grade II complications. The major post-operative complication after 4 weeks of surgery was posterior capsular opacity. 89.8 % of the eyes had a 4 week-post-operative best corrected visual acuity of e” 6/24. The commonest refractive error was myopia with against the rule astigmatism, seen in 86 out of 150 cases. Conclusion: High quality cataract surgery with a low rate of intra-operative complications and good visual outcome can be attained in camp patients operated in the base hospitals, thus justifying more similar screening camps to clear the vast cataract backlog.
