Transient no light perception visual acuity after cataract surgery

Endophthalmitis is the most serious complication of cataract surgery. A cluster of endophthalmitis is a devastating event for surgeons. Pseudomonas aeruginosa is the main causative pathogen of Gram-negative endophthalmitis, which can be suggestive of the occurrence of an outbreak. Ten patients diagnosed with endophthalmitis after cataract surgery performed by one surgeon were analyzed in this study. At presentation, five patients had obvious clinical findings of endophthalmitis with visual acuity of light perception, two patients had poor light perception/no light perception of vision complicated by concomitant keratitis, and three patients had earlier signs of infection (e.g., a lower degree of anterior chamber and vitreous cells, better presenting visual acuity, and greater visibility of the fundus). Investigations revealed that the source of infection was growth of P. aeruginosa on the phaco probe. All of the surgeries had been performed by the same contaminated probe without sterilization between surgeries. This finding emphasizes the importance of strict adherence to sterility protocols during high-risk surgeries such as intraocular surgeries. Additionally, this report aims to emphasize to surgeons that negligence of simple but vital steps of sterility for any reason, such as limitations in time or equipment, can lead to catastrophic events.

Purpose. To report a case of persistent fetal vasculature (PFV) with a retinal detachment that worsened after cataract surgery. Pars plana vitrectomy (PPV) was performed which reduced the vitreous traction and reattached the retina. Observations. A 20-year-old Myanmarese woman presented with a mature cataract, and her vision was light perception. She underwent uneventful cataract surgery with implantation of an intraocular lens. Her visual acuity improved to 20/200 immediately after the surgery. However, fibrotic tissue was observed between the optic nerve head and the posterior capsule. She was diagnosed with PFV, and she was followed without any intervention. One and a half years after the cataract surgery, she had an advanced retinal detachment which extended over the inferior two quadrants. Her vision deteriorated to 20/400. She underwent PPV, and the PFV tissue was removed which resulted in the reattachment of the retina. The visual acuity improved to 20/60. Conclusions. Surgeons should be aware that it is possible to worsen a retinal detachment after cataract surgery in the eyes with PFV. A simple technique to release the anterior-posterior traction by the PPV was sufficient to achieve the reattachment of the retina.

Background: Pediatric cataracts are major causes of children’s blindness. Surgery has proven to be beneficial in terms of visual function prognosis. Contrast sensitivity evaluation after surgery is as important as visual acuity considering that natural world consists of various objects in low-to-medium contrasts. The purpose of this study is to analyze the difference of contrast sensitivity outcomes based on ages at surgery. Method: Retrospective data of children with pediatric developmental cataract from July 2013 to November 2015 were collected. All children who underwent cataract surgery at 60-months-old or less were randomized into two groups, ≤24 months and >24-to-60 months. Contrast sensitivity was then examined with preferential-looking method using Hiding Heidi low-contrast test face chart. The main outcome measures were contrast sensitivity of both groups. Age-at-evaluation, cataract onset, duration of follow-up, duration of deprivation and visual acuity were also noted. Result: Of 14 children (23 eyes), 11 eyes (47,8%) were in ≤24 months group, 12eyes (52,2%) were in >24-to-60 months group. All eyes underwent cataract extraction and similar type of intraocular lens implantation. Mean age-at-surgery was 28,2 months±16,8 (SD). Mean contrast sensitivity for each group was 47,50 %±42,29 and 18,33%±27,38, respectively, with p-value 0,031. Further analysis of Spearman’s correlation test demonstrated significant negative correlation (rs = -0,559; p = 0,006) between the two groups. Conclusion: There was statistically significant difference in contrast sensitivity between those who underwent surgery at ≤24 months and >24-to-60 months. Children who underwent surgery at older ages tend to have better contrast sensitivity afterwards.

Purpose : The aim of this study is to report a case of intraorbital wooden foreign body with intracranial extension to the frontal lobe and its management. Method : This is a descriptive study: A 53 year-old male referred due to wooden stick stucked in the orbital cavity causing protruding eyeball and vital sign instability. Result : Right eye examination revealed light perception visual acuity, with bad light projection and bad color perception, inwardly folded upper eyelid, proptosis, conjunctival chemosis, corneal erosion and edema, dilated pupil with sluggish pupillary light reflex and limited ocular movement in all direction. Vital sign was unstable with decreasing blood pressure, increasing temperature and heart rate. CT Scan showed complete fracture of the orbital roof due to penetration of the wooden stick, pneumoencephalus, cerebral edema and hematoma. Emergency craniotomy was performed to remove the penetrating wooden stick and bone segment in the frontal lobe and fracture repair. Ophthalmologist pulled the remaining stick, released the superior rectus muscle and repaired the lacerated eyelid. Outcome visual acuity was no light perception with lagophthalmos and limited ocular motility. Patient was admitted to Intensive Care Unit one day post-operatively and treated with systemic and topical antibiotic. Conclusion : Any case presenting with intraorbital foreign body must undergo immediate neuroimaging to exclude any intracranial extension, especially in patients with worsening general condition.

Abstract Objective The study aimed to evaluate the safety and efficacy of resident surgeons performing femtosecond laser assisted cataract surgery (FLACS). Methods A retrospective chart review was conducted at the University of Wisconsin-Madison from postgraduate year four residents performing FLACS between 2017 and 2019. Data were also collected from residents performing manual cataract surgery, and attending surgeons performing FLACS for comparison. Recorded data included patient demographics, pre- and postoperative visual acuity, pre- and postoperative spherical equivalent, nuclear sclerotic cataract grade, ocular and systemic comorbidities, intraocular lens, duration of surgery, cumulative dissipated energy (CDE), and intraoperative and postoperative complications. Results A total of 90 cases were reviewed with 30 resident manual cases, 30 resident FLACS cases, and 30 attending FLACS cases. Resident manual (25.5 ± 6.8 minutes) and resident FLACS (17.5 ± 7.1 minutes) cases took a significantly longer time to complete compared with attending FLACS cases (13.6 ± 4.4 minutes; p < 0.001). There was higher CDE in resident FLACS and resident manual cases compared with attending FLACS cases, but the difference was not statistically significant (p = 0.06). Postoperative visual acuity was not statistically different at 1-day and 1-month after surgery among the three groups. Resident FLACS complications, which included one case requiring an intraoperative suture to close the wound, two cases with intraoperative corneal abrasions, two cases with postoperative ocular hypertension, and one case with cystoid macular edema, were not significantly greater than attending FLACS complications (p = 0.30). Conclusion The FLACS performed by resident surgeons had comparable visual acuity outcomes to FLACS performed by attending surgeons, and to manual cataract surgery performed by resident surgeons. However, resident FLACS cases took significantly longer time to complete, and they were associated with a higher CDE and minor complication rate compared with attending FLACS cases. Introducing advanced technologies into surgical training curricula improves resident preparedness for independent practice, and this study suggests FLACS can be incorporated safely and effectively into resident education.

ABSTRACTBackground:Depression is common among older populations with cataract. However, the impact of cataract surgery on depression in both developed and developing countries remains unclear. The aim of this study is to determine the impact of cataract surgery on depressive symptoms and to examine the association between objective visual measures and change in depressive symptoms after surgery among a Vietnamese population in Ho Chi Minh City.Methods:A cohort of older patients with bilateral cataract were assessed the week before and one to three months after first eye surgery only or first- and second-eye cataract surgeries. Visual measures including visual acuity, contrast sensitivity, and stereopsis were obtained. Depressive symptoms were assessed using the 20-item Center for Epidemiological Studies-Depression Scale (CES-D). Descriptive analyses and a generalized estimating equations (GEE) analysis were undertaken to determine the impact of cataract surgery on depressive symptoms.Results:Four hundred and thirteen participants were recruited into the study before cataract surgery. Two hundred and forty-seven completed the follow-up assessment after surgery. There was a significant decrease (improvement) of one point in the depressive symptoms score (p = 0.04) after cataract surgery, after accounting for potential confounding factors. In addition, females reported a significantly greater decrease (improvement) of two points in depressive symptom scores (p = 0.01), compared to males. However, contrast sensitivity, visual acuity, and stereopsis were not significantly associated with change in depressive symptoms scores. First-eye cataract surgery or both-eye cataract surgery did not modify the change in depressive symptoms score.Conclusion:There was a small but significant improvement in depressive symptoms score after cataract surgery for an older population in Vietnam.

Purpose. To assess safety and efficacy of temporal manual small incision cataract surgery (SICS) in context to visual outcome, astigmatism, and complications. Methods. This involved sclerocorneal tunnel, capsulotomy and hydrodissection. The incision was made with number 11 disposable surgical blade (costing Indian Rs. 2.50, $0.05). Nucleus extraction was done by phaco-sandwich method with the help of vectis and dialer. Posterior chamber intraocular lens implantation was done according to biometric findings. A record of intraoperative and postoperative complications was made. The final postoperative assessment of astigmatism was done with spectacle correction on the 45th day as per the refraction findings. Results. Two thousand eyes were operated by temporal, manual small incision sutureless technique. Uncorrected visual acuity was ≥6/18 in 1636 (81.7%) patients on the first postoperative day, in 1652 (82.6%) patients at 2 weeks, and in 1732 (88.6%) patients at 6 weeks. Best-corrected visual acuity (BCVA) ≥6/18 was achieved in 1868 (93.4%) patients at 6 weeks, with 46 (2.3%) having BCVA <6/60, 24 (1.2%) of whom had preexisting retinal pathology. At 6 weeks, 1876 (93.8%) eyes had with-the-rule and 134 (6.2%) against-the-rule astigmatism (mean 0.7±1.25 D). Iris prolapse was noted in 3 (0.15%), wound leak in 3 (0.15%), and transient corneal edema in 136 (6.8%) eyes. Average surgery time was 6 minutes. Conclusions. Temporal SICS with number 11 disposable surgical blade and nucleus delivery by phaco-sandwich method gave excellent outcome with minimal astigmatism and low complication rate at economic cost.

AIM: To assess the patient-reported outcome of phacoemulsification with posterior chamber single focus foldable intraocular lens (SIOL) using the Chinese version of Catquest-8SF questionnaire (Catquest-8SF-CN), evaluate the applicability of Catquest-8SF scale in northern Chinese and its sensitivity to cataract surgery. METHODS: Prospective clinical case follow-up study. The patients were recruited from the Central Hospital of Tai’an and completed the Catquest-8SF questionnaire by face-to-face interviews before and 3mo after surgery at the hospital. RESULTS: A total of 120 cataract patients with median age 67.6y and 52.5% female completed the Catquest-8SF. The Cronbach’s α coefficient of the total scale, daily-activity sub-table and comprehensive-evaluation sub-table were 0.861, 0.853 and 0.748 respectively. There was a high level of consistency between two investigators. The cumulative contribution rate was 66.64% by using the principal component analysis and the maximum variance orthogonal rotation method. The preoperative score of the Catquest-8SF-CN had a significant negative correlation with preoperative binocular mean weighted visual acuity and age (P<0.05), while a significant positive correlation with education level (F=6.094, P<0.001). The patients without systemic comorbidities got higher score than those who with (P<0.05). Three months after surgery, 102 (85%) patients came for follow-up and completed the questionnaire. Significant improvement of visual acuity was observed in both binocular and monocular surgery groups (t=10.404, P<0.001). There was higher improvement in binocular weighted visual acuity of binocular surgery group than in monocular surgery group (t=-20.77, P<0.001). The postoperative score was significantly higher in both groups than before (P<0.001). There was a significant improvement in the total score after cataract surgery. The 94 patients (92.2%) were very satisfied or satisfied with the operation; 92 patients (90.2%) thought the surgery achieved their expectations, and they all felt satisfactory. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery. CONCLUSION: The Chinese version of Catquest-8SF questionnaire is suitable for the age-related cataract population in northern China. It is highly responsive to cataract surgery and brief, so it may have the potential to become part of a routine clinical assessment for cataract surgery in China. The patient’s overall satisfaction is high, which illustrates that the medical service we provide matches the patient’s needs. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery.

Dry Eye Symptoms

Introduction. Dry eye syndrome has become a common problem after ocular surgeries with a significant impact on the quality of life. Many patients, who have undergone cataract surgery, postop?eratively developed dry eye symptoms. Dry eye syndrome is one of the risk factors associated with cataract surgery. Material and Methods. The prospective study included 80 patients. We recorded the self-reported dry eye symptoms, the values of Schirmer test, tear breakup time, and best corrected visual acuity preoperatively, as well as 7 days and 1 month after the surgery. Results. A total of 80 patients were included in the study, 45 (56.2%) females and 35 (43.8%) males. The mean age of patients was 61.5 years (SD ? 6.2, range 57 - 70 years). The best corrected visual acuity at the time of surgery was 0.4 or less in 70 patients (87.5%). Most patients reported a significant improvement in visual acuity after surgery; 68 (85%) eyes achieved a best corrected visual acuity of 0.5 or higher (median 0.7; range 0.5 - 1.0). The mean tear breaking time in cata?ract patients before surgery was 12.4 sec, 7 days after the surgery it was 8.2 sec (p < 0.05) and 1 moth after the surgery 11.1 sec. The majority of patients had mild (47.5%) and moderate (33.75%) Schirmer test values. Dry eye with wetting < 5 mm after 5 minutes was found in 16.2% of patients before cataract surgery; 7 days after the surgery (p < 0.05) it was found in 23.75% of patients and one month after surgery 11.1 sec. A foreign body sensation and watery eye were the most reported symptoms before cataract surgery. Seven days after the surgery foreign body sensation was present in 48.75% and watery eyes in 40% of patients. Conclusion. Significant increase in dry eye symptoms after cataract surgery was found with increasing age. Self reported dry eye problems are more common in patients with lower Schirmer test and best corrected visual acu?ity values before cataract surgery. Patients with concomitant dry eye disease require preoperative and postoperative treatment of dry eye to prevent aggravation of the existing symptoms that may affect the visual outcome after cataract surgery.
