Ng WWV, Thiyagarajan S, Tan C, Chen DZ. A survey exploring ophthalmologists' attitudes and beliefs in performing immediate sequential bilateral cataract surgery in Singapore. Clin Exp Ophthalmol 2024. [PMID: 39091114 DOI: 10.1111/ceo.14431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 07/10/2024] [Accepted: 07/14/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND To evaluate current practice patterns of Immediate Sequential Bilateral Cataract Surgery (ISBCS) by ophthalmologists in Singapore and assess their attitudes towards performing ISBCS in future cataract care. METHODS An anonymised electronic survey, modified to local context from a similar study conducted in the United Kingdom, was distributed to members of the College of Ophthalmologists, Academy of Medicine, Singapore, from 20 June to 1 September 2023. An initial screening question on prior experience with ISBCS directed the rest of the survey. Questions explored ophthalmologists' current ISBCS practice patterns and the importance of factors affecting their willingness to perform ISBCS. Results were descriptively analysed. RESULTS Results collated 2 months upon survey dissemination saw a total of 58 respondents from 235 eligible members (24.7% response rate). Of these, 16 (27.6%) were currently performing ISBCS, 37 (63.8%) had never performed, and 5 (8.6%) had stopped performing. In considering ISBCS, patient convenience (n = 11, 68.8%) and reduced hospital visits (n = 8, 50.0%) were the most important factors nominated. The most important barriers to performing ISBCS were medico-legal issues (n = 31, 83.8%) and risk of endophthalmitis (n = 27, 73.0%), followed by perceived lack of evidence for its effectiveness (n = 19, 51.4%). CONCLUSION This is one of the first studies evaluating ophthalmologists' sentiments towards performing ISBCS in an Asian country. It highlights some of the most pertinent barriers and concerns that ophthalmologists face in performing and offering ISBCS. This study provides a better understanding of the potential role and prospects of ISBCS in future cataract care in Singapore.

CANADIAN JOURNAL OF OPHTHALMOLOGY 2024; 59:146-153. [PMID: 37290485 DOI: 10.1016/j.jcjo.2023.04.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 04/18/2023] [Accepted: 04/24/2023] [Indexed: 06/10/2023]
Abstract
OBJECTIVE To evaluate the perception of immediately sequential bilateral cataract surgery (ISBCS) among Canadian ophthalmologists. DESIGN An anonymous survey was sent to all active members of the Canadian Ophthalmological Society. METHODS Basic demographic information, cataract surgery practice patterns, and perceived advantages, disadvantages, and concerns regarding ISBCS were collected from respondents. RESULTS A total of 352 ophthalmologists answered the survey. Among these, 94 respondents (27%) practice ISBCS routinely, 123 (35%) practice ISBCS in exceptional cases, and 131 (37%) do not practice ISBCS. ISBCS practitioners were significantly younger than nonpractitioners (p < 0.001) and had a shorter duration of practice (p < 0.001). The prevalence of ISBCS practitioners also varied significantly by province (p < 0.001): most practitioners who routinely practice ISBCS were from Quebec (n = 44; 48%), where financial disincentives are lowest in the country. The main work setting of ISBCS practitioners was academic centres (n = 39; 42%) as opposed to private or community settings (p < 0.001). The main reason for performing ISBCS was more efficient operating theatre use (n = 142; 65%). The main concerns regarding ISBCS were the risk of bilateral complications (n = 193; 57%) and the lack of refractive outcomes for second-eye surgery (n = 184; 52%). The COVID-19 pandemic positively influenced the view of 152 respondents (43%), but this was mostly among practitioners who already performed ISBCS routinely (n = 77; 84%). CONCLUSIONS ISBCS practitioners are more likely younger ophthalmologists working in academic centres. Quebec has the highest prevalence of ISBCS practitioners. ISBCS practitioners were positively influenced by the COVID-19 pandemic to offer ISBCS more often compared with non-ISBCS practitioners.

Abstract
BACKGROUND Due to surgical capacity pressures, induced by the COVID-19 pandemic, immediate bilateral simultaneous cataract surgery (ISBCS) has been utilised increasingly throughout the U.K. This surgical method comes with both novel risks and benefits, so the consent process must be modified. Prior randomised trials have demonstrated that appropriate online information may act as an adjunct to the surgical consent process. This study aims to assess the quality of available internet information for ISBCS. METHODS Terms searched were 'bilateral cataract surgery patient information', 'double cataract surgery patient information', and 'immediate sequential bilateral cataract surgery patient information'. The Google search engine was used. The DISCERN instrument and JAMA benchmarks were used to assess healthcare information for quality. The Flesch Reading Ease Score (FRE), Flesch Kincaid Grade (FKG) Level and Gunning Fog Score (GFS) were used to assess for readability. HONcode certification was used to assess transparency and quality. RESULTS Forty-six websites were found. The average DISCERN score was 41.3, meaning a "fair" quality which is below what many patients would anticipate discovering when trying to find information. National Healthcare Service websites had higher DISCERN scores than private healthcare-provided websites (p < 0.01; 95% CI: 1.13-1.88.). CONCLUSIONS Fair patient information for ISBCS has been demonstrated. Specific internet information sources with appropriate information should be further developed, with cited sources, and patients signposted to them if felt appropriate.

Abstract
PURPOSE To report the refractive outcomes of long (≥25.00 mm) and short (≤22.00 mm) axial length (AL) eyes undergoing immediately sequential bilateral cataract surgery (ISBCS). METHODS In this retrospective cohort study, patients who underwent ISBCS were identified and eyes of patients with bilateral long and short ALs were included. Pre- and postoperative biometry, autorefraction, and ocular comorbidities or complications were recorded. The primary outcome was the mean refractive prediction error. RESULTS Thirty-seven patients (74 eyes) with long ALs and 18 patients (36 eyes) with short ALs were included. The means ± standard deviations of the ALs were 26.40 ± 1.38 mm and 21.44 ± 0.46 mm in the long and short AL groups, respectively. In long AL eyes, the mean absolute error from the biometry-predicted refraction was - 0.16 ± 0.46 D, corresponding to 74% of eyes achieving a refraction within ±0.50 D of the predicted value. In short AL eyes, the mean absolute error was - 0.63 ± 0.73 D, corresponding to 44% of eyes achieving a refraction within ±0.50 D of the predicted value. Eight (44.4%) patients with short AL eyes had a myopic deviation greater than ±0.50 D from the predicted result in both eyes. CONCLUSIONS Compared to patients with long AL eyes, ISBCS in patients with short ALs had a wider variance in refractive outcome and a lower rate of achieving a postoperative refraction within ±0.50 D of the predicted target.

Abstract
BACKGROUND To explore the changes of cytokines expression in aqueous humor (AH) of eyes of patients with congenital cataract (CC) who underwent delayed sequential bilateral cataract surgery (DSBCS). METHODS 28 patients with CC underwent DSBCS. AH samples were collected from each eye before surgery. The contents of cytokines in AH were detected by Luminex xMAP Technology. RESULTS There was no significant difference in the expression of IL-8, IP-10, MCP-1 and PDGFAA in the AH of the first and second eyes (P = 0.35, 0.39, 0.17, respectively). The level of IL-8 in the first-eye AH was negatively correlated with age (ρ=- 0.519, P = 0.008). IP-10 and MCP-1 in the second-eye AH were negatively correlated with age (ρ=- 0.483, P = 0.009; ρ=- 0.445, P = 0.018,respectively). CONCLUSION The first-eye surgery in patients with CC may not cause the change of cytokines in the contralateral eye. The expression of IL-8, IP-10 and MCP-1 in the AH was negatively correlated with the age of patients. TRIAL REGISTRATION The study was registered at www.chictr.org.cn on March 22, 2022 and the clinical trial number is ChiCTR2200057927.

Abstract
PURPOSE To evaluate the preoperative and intraoperative features, intraoperative and postoperative complications and postoperative satisfaction of patients who underwent immediate sequential bilateral cataract surgery (ISBCS) during the COVID-19 pandemic. METHODS The study included ISBCS patients from September 2021 through January 2022. Demographics, comorbidities, type of anesthesia (topical/general), intraoperative complications, postoperative refractive errors, and complications were examined. The one-month postoperative appointment included a patient satisfaction questionnaire. RESULTS ISBCS was performed in 206 eyes of 103 patients. Intraoperative complications did not occur in 99 (96.1%) of ISBCS patients. No patients had visually significant corneal edema, wound leakage, endophthalmitis, or toxic anterior segment syndrome during postoperative follow-up. Final manifest spherical equivalent refraction was less than 1.00 D in all patients and less than 0.50 D in 70.7% of patients. In the questionnaire given to the patients at the one-month follow-up, 96.1% of patients did not change their preference for surgery on the same day. CONCLUSION ISBCS provides an advantage during the pandemic period by reducing hospital visits, especially for the elderly population and patients with comorbidities. ISBCS is a safe and reasonable method that can be used during a pandemic due to the low rates of complications, the success of the refractive results, and the high patient satisfaction rates.

Abstract
PURPOSE OF REVIEW The aim of this study was to present an overview of recent publications and opinions in the field of same-day bilateral cataract surgery. RECENT FINDINGS A Cochrane review was published comparing immediate sequential bilateral cataract surgery (ISBCS) and delayed sequential bilateral cataract surgery (DSBCS) with regard to safety outcomes, costs and cost-effectiveness. In addition, several large database studies provided more information on incidences of rare complications such as unilateral and bilateral endophthalmitis rates. SUMMARY Recently available evidence showed that ISBCS is an effective and cost-effective alternative to DSBCS. Nonetheless, additional (randomized) registry studies, randomized controlled trials and cost-effectiveness studies are needed to evaluate bilateral endophthalmitis rates, refractive outcomes and cost-effectiveness of ISBCS compared with DSBCS.

Abstract
We investigated the proportions of immediate sequential bilateral cataract surgery (ISBCS) and unilateral cataract surgery during the coronavirus disease 2019 pandemic and compared visual outcomes between the two groups in a tertiary hospital in South Korea. We reviewed 441 cataract surgeries performed between March 1, 2021, and October 31, 2021, at Korea University Guro Hospital by a single surgeon (J.S.S). Medical records of demographics, preoperative visual acuity, corneal astigmatism, axial length, preoperative spherical equivalent, preoperative target (using Barrett's Universal 2 formula), postoperative visual acuity, postoperative refractive error, and postoperative complications were evaluated. Among all patients, 322 (73.0%) eyes underwent ISBCS, and 119 (27.0%) eyes underwent unilateral cataract surgery. The preoperative corrective distance visual acuity (CDVA) was lower in the unilateral cataract surgery group (0.40 ± 0.45 logMAR) than the ISBCS group (0.28 ± 0.16 logMAR, P = 0.008), whereas there was no significant difference in postoperative CDVA between the two groups (0.06 ± 0.10 logMAR vs. 0.07 ± 0.16 logMAR, P = 0.63). There was also no difference in the absolute refractive error between the two groups (0.46 ± 0.37 diopters [D] vs. 0.42 ± 0.38 D, P = 0.63). The preoperative CDVA (P = 0.000) was the significant factor influencing absolute refractive error (r = 0.191, P < 0.001). There was no difference in complications between the two groups, although two patients in the ISBCS group complained of postoperative strabismus.

Abstract
The exponential increase in world population and average human lifespan is expected to result in geriatric population globally. The problem of preventable blindness due to cataract will increase manifold. Simultaneous Bilateral cataract surgery (SBCS) is a viable option in such subset of patients. Despite faster visual recovery, economic benefits to patients and health care providers, decreased risk of complications associated with General anaesthesia, there is significant resistance in accepting SBCS as a routine procedure. Bilateral endophthalmitis is the main deterrent in performing ISBCS. This case highlights successful ISBCS in 36 years old female patient with Down's syndrome.

Abstract
The World Health Organization (WHO) is developing a Package of Eye Care Interventions (PECI) to facilitate the integration of eye care into Universal Health Coverage. This paper presents the results of a systematic review of clinical practice guidelines for cataract in adults, to help inform PECI development. We searched academic and guideline databases, and websites of professional associations, for guidelines published between January 2010 and April 2020. Guidelines were excluded if there was commercial funding or unmanaged conflicts of interest. Quality appraisal was conducted using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool. We identified 3778 reports, 35 related to cataract guidelines, four of which met the inclusion criteria (United Kingdom: 2, United States: 1, Iran: 1). The recommendations across the four guidelines covered pre-operative (43%), intra-operative (37%), and post-operative interventions (20%). Most ‘strong’ recommendations were supported by good quality evidence. Differences in recommendations across guidelines may be attributable to time of publication or regional differences in surgical practice. Few guidelines met the quality criteria, and only three countries were represented. The results of this step of the PECI development process will inform subsequent phases for development of the WHO’s package of evidence-based eye care interventions for cataract.

Abstract
PURPOSE To evaluate refractive outcomes for the Clareon monofocal intraocular lens (IOL) in terms of achieved target refraction for the ORA (ALCON) intraoperative wavefront aberrometry device and preoperative noncontact biometry. SETTING University Eye Clinic Maastricht, Maastricht University Medical Center+, the Netherlands. DESIGN Prospective observational clinical trial. METHODS Patients with bilateral age-related cataracts undergoing phacoemulsification, either by delayed sequential surgery or on the same day, were included in the study. Exclusion criteria were an increased risk for refractive surprise or complicated surgery. Implanted IOL power was based on noncontact optical biometry data using the Barrett Universal II (BU-II) formula, optimized for the Clareon IOL. Postoperative subjective refraction was measured 4 to 6 weeks after surgery. Catquest-9SF questionnaires were completed preoperatively and 3 months after surgery. RESULTS 100 eyes (51 patients) were included. The percentages of eyes within 1.0 diopters (D), 0.75 D, 0.50 D, and 0.25 D of target for ORA vs BU-II were 84% (84 eyes), 72% (72 eyes), 57% (57 eyes), and 21% (21 eyes) vs 97% (97 eyes), 88% (88 eyes), 77% (77 eyes), and 53% (53 eyes), respectively. Mean absolute prediction error was significantly higher for ORA vs preoperative biometry (P < .001). After global optimization, the prediction accuracy of ORA improved significantly (P < .001). Catquest-9SF questionnaires showed improved levels of ability at 3 months after surgery (P < .001). CONCLUSIONS This study showed lower percentages of eyes within target refraction for ORA (prior to lens constant optimization) compared with the BU-II formula when implanting the Clareon IOL. However, prediction accuracy of ORA improved significantly after global optimization. Therefore, further intraoperative measurements, postoperative measurements, and optimization are needed to improve the ORA prediction for this IOL.

Abstract
BACKGROUND Age-related cataract affects both eyes in most cases. Most people undergo cataract surgery in both eyes on separate days, referred to as delayed sequential bilateral cataract surgery (DSBCS). An alternative procedure involves operating on both eyes on the same day, but as two separate procedures, known as immediate sequential bilateral cataract surgery (ISBCS). Potential advantages of ISBCS include fewer hospital visits for the patient, faster visual recovery, and lower healthcare costs. Nevertheless, concerns exist about possible bilateral, postoperative, sight-threatening adverse effects with ISBCS. Therefore, there is a clear need for evaluating evidence regarding the safety, effectiveness, and cost-effectiveness of ISBCS versus DSBCS. OBJECTIVES To assess the safety of ISBCS compared to DSBCS in people with bilateral age-related cataracts and to summarise current evidence for the incremental resource use, utilities, costs, and cost-effectiveness associated with the use of ISBCS compared to DSBCS in people with bilateral age-related cataracts (primary objectives). The secondary objective was to assess visual and patient-reported outcomes of ISBCS compared to DSBCS in people with bilateral age-related cataracts. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register; 2021, Issue 5); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov; the WHO ICTRP; and DARE and NHS EED on the CRD Database on 11 May 2021. There were no language restrictions. We limited the searches to a date range of 2007 onwards. SELECTION CRITERIA We included randomised controlled trials (RCTs) to assess complications, refractive outcomes, best-corrected distance visual acuity (BCDVA) and patient-reported outcome measures (PROMs) with ISBCS compared to DSBCS. We included non-randomised (NRSs), prospective, and retrospective cohort studies comparing ISBCS and DSBCS for safety assessment, because of the rare incidence of important adverse events. To assess cost-effectiveness of ISBCS compared to DSBCS, we included both full and partial economic evaluations, and both trial-based and model-based economic evaluations. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures and assessed risk of bias for NRSs using the ROBINS-I tool. For cost-evaluations, we used the CHEC-list, the CHEERS-checklist, and the NICE-checklist to investigate risk of bias. We assessed the certainty of evidence with the GRADE tool. We reported results for economic evaluations narratively. MAIN RESULTS We included 14 studies in the review; two RCTs, seven NRSs, and six economic evaluations (one study was both an NRS and economic evaluation). The studies reported on 276,260 participants (7384 for ISBCS and 268,876 for DSBCS) and were conducted in Canada, the Czech Republic, Finland, Iran, (South) Korea, Spain (Canary Islands), Sweden, the UK, and the USA. Overall, we considered the included RCTs to be at 'high to some concerns' risk of bias for complications, 'some concerns' risk of bias for refractive outcomes and visual acuity, and 'high' risk of bias for PROMs. The overall risk of bias for NRSs was graded 'serious' regarding complications and 'serious to critical' regarding refractive outcomes. With regard to endophthalmitis, we found that relative effects were estimated imprecisely and with low certainty, so that relative estimates were not reliable. Nonetheless, we found a very low risk of endophthalmitis in both ISBCS (1/14,076 participants) and DSBCS (55/556,246 participants) groups. Based on descriptive evidence and partially weak statistical evidence we found no evidence of an increased risk of endophthalmitis with ISBCS. Regarding refractive outcomes, we found moderate-certainty (RCTs) and low-certainty (NRSs) evidence there was no difference in the percentage of eyes that did not achieve refraction within 1.0 dioptre of target one to three months after surgery (RCTs: risk ratio (RR) 0.84, 95% confidence interval (CI) 0.57 to 1.26; NRSs: RR 1.02, 95% CI 0.60 to 1.75). Similarly, postoperative complications did not differ between groups (RCTs: RR 1.33, 95% CI 0.52 to 3.40; NRSs: 1.04, 95% CI 0.47 to 2.29), although the certainty of this evidence was very low for both RCTs and NRSs. Furthermore, we found low-certainty (RCTs) to very low-certainty (NRSs) evidence that total costs per participant were lower for ISBCS compared to DSBCS, although results of individual studies could not be pooled. Only one study reported on cost-effectiveness. This study found that ISBCS is cost-effective compared to DSBCS, but did not measure quality-adjusted life years using preferred methods and calculated costs erroneously. Finally, regarding secondary outcomes, we found limited evidence on BCDVA (data of two RCTs could not be pooled, although both studies individually found no difference between groups (very low-certainty evidence)). Regarding PROMs, we found moderate-certainty evidence (RCTs only) that there was no difference between groups one to three months after surgery (standardised mean difference -0.08, 95% CI -0.19 to 0.03). AUTHORS' CONCLUSIONS Current evidence supports there are probably no clinically important differences in outcomes between ISBCS and DSBCS, but with lower costs for ISBCS. However, the amount of evidence is limited, and the certainty of the evidence was graded moderate to very low. In addition, there is a need for well-designed cost-effectiveness studies.

Ophthalmologists' attitudes towards immediate sequential bilateral cataract surgery (ISBCS): a Dutch national survey. J Cataract Refract Surg 2022; 48:1044-1049. [PMID: 35239579 PMCID: PMC9415210 DOI: 10.1097/j.jcrs.0000000000000922] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 02/03/2022] [Indexed: 11/26/2022]
Abstract
PURPOSE To evaluate current practice patterns of immediate sequential bilateral cataract surgery (ISBCS) in the Netherlands and assess ophthalmologists' attitudes towards performing ISBCS in future cataract care. SETTING Dutch ophthalmic society members. DESIGN Cross-sectional study (national survey). METHODS An electronic survey on ISBCS was sent as part of an annual survey on cataract practice patterns to members of the Dutch ophthalmic society. Questions regarding current ISBCS practice patterns, willingness to perform ISBCS routinely in future care, reasons for performing ISBCS and reasons for not performing ISBCS were included. Data were analysed using descriptive statistics. RESULTS In total, 237/520 survey recipients (45.6%) responded to the overall survey. Data on the ISBCS questions was available from 227 respondents. Sixty-two ophthalmologists (27.3%) currently performed ISBCS, predominantly in low patient-volumes (90.3% in one to five patients per month). However, 108/227 ophthalmologists (47.6%) considered performing ISBCS routinely in future practice. Procedures for which ISBCS was mainly considered included age-related cataract surgery using topical and general anaesthesia. Availability of separate products and instruments for both eyes and patient advantages were considered of high importance when performing ISBCS. Main reasons for not performing ISBCS included the risk of endophthalmitis and potential medico-legal aspects. CONCLUSIONS Although ISBCS is currently no routine procedure in the Netherlands, it is considered by almost 50% of surgeons. In order to improve implementation on a national level, potential barriers identified in this survey (fear of bilateral endophthalmitis, potential medico-legal issues, a lack of availability of separate products for both eyes) should be addressed.

Endophthalmitis Rate in Immediately Sequential versus Delayed Sequential Bilateral Cataract Surgery within the Intelligent Research in Sight (IRIS®) Registry Data. Ophthalmology 2022; 129:129-138. [PMID: 34265315 PMCID: PMC8755857 DOI: 10.1016/j.ophtha.2021.07.008] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 06/11/2021] [Accepted: 07/06/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To compare the rate of postoperative endophthalmitis after immediately sequential bilateral cataract surgery (ISBCS) versus delayed sequential bilateral cataract surgery (DSBCS) using the American Academy of Ophthalmology Intelligent Research in Sight (IRIS®) Registry database. DESIGN Retrospective cohort study. PARTICIPANTS Patients in the IRIS Registry who underwent cataract surgery from 2013 through 2018. METHODS Patients who underwent cataract surgery were divided into 2 groups: (1) ISBCS and (2) DSBCS (second-eye surgery ≥1 day after the first-eye surgery) or unilateral surgery. Postoperative endophthalmitis was defined as endophthalmitis occurring within 4 weeks of surgery by International Classification of Diseases (ICD) code and ICD code with additional clinical criteria. MAIN OUTCOME MEASURES Rate of postoperative endophthalmitis. RESULTS Of 5 573 639 IRIS Registry patients who underwent cataract extraction, 165 609 underwent ISBCS, and 5 408 030 underwent DSBCS or unilateral surgery (3 695 440 DSBCS, 1 712 590 unilateral surgery only). A total of 3102 participants (0.056%) met study criteria of postoperative endophthalmitis with supporting clinical findings. The rates of endophthalmitis in either surgery eye between the 2 surgery groups were similar (0.059% in the ISBCS group vs. 0.056% in the DSBCS or unilateral group; P = 0.53). Although the incidence of endophthalmitis was slightly higher in the ISBCS group compared with the DSBCS or unilateral group, the odds ratio did not reach statistical significance (1.08; 95% confidence interval, 0.87-1.31; P = 0.47) after adjusting for age, sex, race, insurance status, and comorbid eye disease. Seven cases of bilateral endophthalmitis with supporting clinical data in the DSBCS group and no cases in the ISBCS group were identified. CONCLUSIONS Risk of postoperative endophthalmitis was not statistically significantly different between patients who underwent ISBCS and DSBCS or unilateral cataract surgery.

Trends, Factors, and Outcomes Associated with Immediate Sequential Bilateral Cataract Surgery (ISBCS) Among Medicare Beneficiaries. Ophthalmology 2021; 129:478-487. [PMID: 34971649 DOI: 10.1016/j.ophtha.2021.12.015] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 12/14/2021] [Accepted: 12/22/2021] [Indexed: 11/26/2022] Open
Abstract
PURPOSE To report the incidence of immediate (ISBCS) and delayed sequential bilateral cataract surgery (DSBCS) and identify factors associated with undergoing ISBCS. DESIGN Retrospective cohort study. SUBJECTS Medicare beneficiaries aged ≥65 who underwent ISBCS and DSBCS from 2011 to 2019. METHODS Population-based analysis of the 100% Medicare fee-for-service carrier claims data. Logistic regression models were performed to evaluate factors associated with ISBCS. MAIN OUTCOME MEASURES 1) Incidence of ISBCS and DSBCS, 2) demographic, ocular and medical characteristics associated with receipt of ISBCS, and 3) rates of endophthalmitis and cystoid macular edema (CME) after ISBCS or DSBCS. RESULTS A total of 4,014 (0.2%) ISBCS and 1,944,979 (99.8%) DSBCS patients were identified. Black (OR:2.31, 95%CI: 2.06-2.59), Asian (OR:1.82, 95%CI: 1.51-2.12), or Native American (OR:2.42, 95%CI: 1.81-3.23) patients were more likely to receive ISBCS compared to White patients. Patients residing in rural areas had higher likelihood of ISBCS (OR:1.26, 95%CI: 1.17-1.35) compared to metropolitan areas. Patients operated at a hospital compared to ambulatory setting (OR:2.71, 95%CI: 2.53-2.89) were more likely to receive ISBCS. Patients with bilateral complex vs. non-complex cataract (OR:3.23, 95%CI: 2.95-3.53) were more likely to receive ISBCS. Patients with a Charlson comorbidity index (CCI) of 1-2 (OR:1.45, 95%CI: 1.29-1.62), 3-4 (OR:1.70, 95%CI: 1.47-1.97), 5-6 (OR:1.97, 95%CI: 1.62-2.39), and CCI≥7 (OR:1.97, 95%CI: 1.55-2.50) were all more likely to receive ISBCS compared to those with CCI=0. In contrast, patients with glaucoma (OR:0.82, 95%CI: 0.76-0.89), macular degeneration (OR:0.75, 95%CI: 0.68-0.82), and macular hole/epiretinal membrane (OR:0.55, 95%CI: 0.48-0.65) were less likely to undergo ISBCS compared to those without. Cumulatively, there was no significant difference in endophthalmitis rate within 42 days between ISBCS (1.74 per 1,000 ISBCS) and DSBCS (1.01 per 1,000 DSBCS; p=0.15). Similarly, there was no significant cumulative difference between ISBCS (1.79 per 100 ISBCS) and DSBCS (1.96 per 100 DSBCS) CME rates (p=0.48). CONCLUSION Overall utilization of ISBCS among Medicare beneficiaries remains low over the past decade, though rates of endophthalmitis and CME were comparable to DSBCS. Race, geography, systemic and ocular comorbidities were associated with receiving ISBCS. ISBCS represents a potential opportunity to improve access to cataract surgery.

Abstract
This review presents the main pros and cons of immediately sequential bilateral cataract surgery versus delayed sequential bilateral cataract surgery. The main arguments against immediately sequential bilateral cataract surgery are the likelihood of postoperative bilateral endophthalmitis and refractive errors. At the same time, a careful selection of patients, implementation of safety recommendations and the use of intracameral antibiotics, combined with the improvement of formulas for calculating intraocular lenses, provide the advantages of immediately sequential bilateral cataract surgery associated with the rapid rehabilitation of patients after surgery and economic reasons.

Abstract
BACKGROUND Jurisdictions worldwide ramped down ophthalmic surgeries to mitigate the effects of COVID-19, creating a global surgical backlog. We sought to predict the long-term impact of COVID-19 on the timely delivery of non-emergent ophthalmology sub-specialty surgical care in Ontario. METHODS This is a microsimulation modelling study. We used provincial population-based administrative data from the Wait Time Information System database in Ontario for January 2019 to May 2021 and facility-level data for March 2018 to May 2021 to estimate the backlog size and wait times associated with the COVID-19 pandemic. For the postpandemic recovery phase, we estimated the resources required to clear the backlog of patients accumulated on the wait-list during the pandemic. Outcomes were accrued over a time horizon of 3 years. RESULTS A total of 56 923 patients were on the wait-list in the province of Ontario awaiting non-emergency ophthalmic surgery as of Mar. 15, 2020. The number of non-emergency surgeries performed in the province decreased by 97% in May 2020 and by 80% in May 2021 compared with the same months in 2019. By 2 years and 3 years since the start of the pandemic, the overall estimated number of patients awaiting surgery grew by 129% and 150%, respectively. The estimated mean wait time for patients for all subspecialty surgeries increased to 282 (standard deviation [SD] 91) days in March 2023 compared with 94 (SD 97) days in 2019. The provincial monthly additional resources required to clear the backlog by March 2023 was estimated to be a 34% escalation from the prepandemic volumes (4626 additional surgeries). INTERPRETATION The estimates from this microsimulation modelling study suggest that the magnitude of the ophthalmic surgical backlog from the COVID-19 pandemic has important implications for the recovery phase. This model can be adapted to other jurisdictions to assist with recovery planning for vision-saving surgeries.

Use of Simultaneous Bilateral Cataract Surgery (SBCS) to Optimize Parameters Affecting the Subjective Perception of the Procedure. J Ophthalmol 2021; 2021:5584906. [PMID: 34194819 PMCID: PMC8214475 DOI: 10.1155/2021/5584906] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 05/11/2021] [Accepted: 06/02/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction Simultaneous Bilateral Cataract Surgery (SBCS) is still a relatively controversial procedure. The main objection is the risk of bilateral endophthalmitis or bilateral refractive error. However, SBCS has also some advantages (faster visual rehabilitation, lower risk of nosocomial infection, and lower cost). Performing surgery on both eyes in one session has one additional advantage which has not yet been described in the literature (according to the information available to authors). It allows surgeons to distinguish the effect of minor differences in the surgical protocol on the subjective perception of the procedure more accurately, which is a more suitable method than comparing two independent groups of patients. Purpose To compare the effect of minor changes in the surgical protocol during SBCS on intraindividual subjective perception of surgery (pain, pressure, glare, and perception of the duration of the surgery). Methods During the surgery of the right and left eyes of one patient, we randomly changed one surgical parameter (use of intracameral anesthesia, light intensity of the operating microscope, type of eyelid speculum, creation of the posterior circular capsulorhexis, and communication with the patient during surgery). Patients immediately after both surgeries subjectively evaluated the perception of pain (on the scale 0–10), pressure, and glare (on the scale 0–5) and estimated the duration of the surgery, separately for each eye. Each change was evaluated in a group of 50 patients. Results In the control group with no parameters changed, we noted no difference in subjective perception of the first and second surgery. In subgroups, where we changed the protocol, we detected only minor differences in subjective perception of pain, pressure, glare, and duration of the surgery. Only one statistically significant difference in subjective pain perception was in the subgroup where we used eye intracameral anesthesia (0.34 eyes with intracameral anesthesia, 0.44 eyes with only topical anesthesia). We did not note any statistically significant differences in the perception of the time of surgery. Conclusion SBCS can be used to optimize the parameters of cataract surgery. In our study, we noted a positive effect of intracameral anesthesia on subjective perception of surgery.

Abstract
PURPOSE To compare immediate sequential bilateral corneal cross-linking (CXL), wherein both eyes are treated on the same day, to delayed sequential bilateral CXL, where each eye is treated on different days for bilateral progressive keratoconus. METHODS This was a retrospective case note review of all patients who underwent sequential CXL or delayed CXL for keratoconus at Royal Liverpool University Hospital, United Kingdom. Parameters assessed were the change in maximum keratometry and minimum central corneal thickness on corneal tomography scan, corrected distance visual acuity, and cost estimates of treatment. RESULTS A total of 38 patients (31 men and 7 women) with keratoconus with a mean age of 25.3 ± 7.0 years were included. Twenty patients received sequential CXL and 18 received delayed CXL treatment. In both the sequential CXL and delayed CXL groups, the treated eye(s) showed no evidence of progression after the corneal CXL treatment at last follow-up visit after 358 ± 158 days for sequential CXL and 451 ± 205 days for delayed CXL. There were no complications from the treatment in either group. In the delayed CXL group, the mean time interval between the two CXL procedures was 146 ± 129 days. Five of 18 patients (27%) showed progression of keratoconus in their second eye during the waiting time. Economical evaluation showed that four visits were saved for each sequential CXL treatment compared to delayed CXL. CONCLUSIONS Delayed CXL carries a risk of progression in the second eye and is associated with a higher economic burden. [J Refract Surg. 2020;36(8):552-556.].

Abstract
BACKGROUND/AIMS Children with bilateral cataracts may undergo immediate sequential bilateral cataract surgery (ISBCS), which involves surgery on both eyes during the same general anaesthesia, or delayed sequential bilateral cataract surgery (DSBCS), which involves operating on each eye on separate days and requires a second anaesthesia. ISBCS is viewed with caution because of the risk of bilateral endophthalmitis. Proponents of ISBCS emphasise that the incidence of serious complications is low and is outweighed by benefits such as avoidance of multiple anaesthesia, faster visual rehabilitation and potential for decreased costs. However, there is a paucity of literature regarding the cost-effectiveness of ISBCS in children. We conducted a cost-effectiveness analysis to determine whether ISBCS is more cost-effective than DSBCS from the societal and health system perspectives in Ontario, Canada, which has a universal, single-payer system. METHODS A retrospective analysis of children who underwent ISBCS or DSBCS at a tertiary referral paediatric hospital was conducted. A decision tree was constructed using TreeAge Pro 2018 software. Clear visual axis was the measure of effectiveness. A time horizon of 8 weeks postoperatively was adopted. Both direct and indirect costs were included. RESULTS Fifty-three children were included, 37 in the ISBCS group and 16 in the DSBCS group. ISBCS and DSBCS were equally effective. ISBCS resulted in cost-savings of $3,776 (95% CI:-$4,641 to $12,578) CAD, per patient, from the societal perspective and $2,200 (95% CI:-$5,615 to $10,373) CAD per patient from the health system perspective. CONCLUSION ISBCS was less costly than DSBCS from both societal and health system perspectives while being equally effective.

Abstract
The debate on role of ‘simultaneous bilateral cataract surgery’ (SBCS) continues. The world population has exponentially increased during last fifty years and average human lifespan has increased by a decade during the last century. This translates to ever increasing geriatric population with its inherent problem of preventable blindness because of cataract formation in the elderly. We are adding to the backlog of cataract surgeries not only in the ‘developing world’ but also in the ‘developed world.’ Times demand that we reconsider our old fashioned approach of staggering bilateral cataract surgeries. Serious, but a potential, risk of simultaneous bilateral infection/endophthalmitis has been the biggest deterrent in acceptance of SBCS as a routine procedure. The opponents of SBCS strongly believe in this argument that has not been documented when strictly followed the recommendations regarding separate procedures of each eye. The advantages of reducing the ever-increasing backlog of preventable/treatable blindness, faster visual recovery, economic benefits to patients as well as health care providers, lesser risk of amblyopia in pediatric population, and decreased risk of as serious a complication as death by exposure to general anesthesia in pediatric and adult population, etc. outweigh the disadvantages of SBCS when compared with ‘delayed bilateral cataract surgery’ (DBCS). SBCS is favored over DBCS in pediatric population and in uncooperative, mentally retarded and physically disabled adults needing general anesthesia to reduce the risks and complications of general anesthesia. Considering such factors and review of available literature strongly support that SBCS has a definite role where indicated, under certain circumstances, and in certain select group of patients in both developing as well as developed countries.

JOURNAL OF MEDICAL ETHICS 2020; 47:medethics-2020-106412. [PMID: 32958695 PMCID: PMC8639900 DOI: 10.1136/medethics-2020-106412] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 07/22/2020] [Accepted: 07/28/2020] [Indexed: 06/11/2023]
Abstract
PURPOSE The purported benefits and risks of immediately sequential bilateral cataract surgery (ISBCS) have been well described, yet the procedure remains controversial among UK ophthalmologists. As many of the controversies of ISBCS are underpinned by ethical dilemmas, the aim of this work was to explore the ethical perspectives of ISBCS from a variety of stakeholder viewpoints. METHOD A semi-structured independent stakeholder meeting was convened at the Royal College of Ophthalmologists London headquarters in June 2018. In total, 29 stakeholders attended the meeting. The professional characteristics of stakeholders included but were not limited to: ophthalmologists (9), patients (5), religious leaders (4), ethicists (2), lawyers (2) and commissioners (1). Thematic qualitative analysis using methodology proposed by Braun and Clarke was conducted on the resultant transcript of the discussion. RESULTS Themes identified include: (1) beneficence and non-maleficence (patient benefits, patient risks, the uncertainties of risk, patient interpretation of the risk-benefit analysis); (2) autonomy (informed consent, the barriers to communication); (3) distributive justice (the allocation of resources: the individual vs the collective). CONCLUSION This analysis provides a reference point for the ethical factors surrounding ISBCS. The stakeholders concluded that this approach was an ethical undertaking provided patient autonomy was appropriately attained. This requires a patient's interpretation of the risk-benefit balance, which must include an understanding of the low but unquantifiable risk of severe complications. A surgeon must aim to minimise risks through the adaption of accepted surgical protocols and by performing appropriate patient selection. Currently, cost savings to healthcare that may occur following the implementation of ISBCS should be considered a secondary benefit of the protocol.

Cost-effectiveness of immediate versus delayed sequential bilateral cataract surgery in the Netherlands (the BICAT-NL study): study design of a prospective multicenter randomised controlled trial. BMC Ophthalmol 2020; 20:257. [PMID: 32600295 PMCID: PMC7323372 DOI: 10.1186/s12886-020-01521-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 06/17/2020] [Indexed: 12/04/2022] Open
Abstract
Background Cataract surgery is one of the most frequently performed types of surgery. Most patients suffer from bilateral cataract and while cataract surgery of only one eye is effective in restoring functional vision, second-eye surgery leads to further improvements in health-related quality of life, and is cost-effective. At present, most patients undergo cataract surgery in both eyes on separate days as recommended in national guidelines, referred to as delayed sequential bilateral cataract surgery (DSBCS). An alternative procedure involves operating both eyes on the same day, but as separate procedures, known as immediately sequential bilateral cataract surgery (ISBCS). The aim of this study is to evaluate the effectiveness and costs of ISBCS compared to DSBCS, in order to test the hypothesis that ISBCS is non-inferior to DSBCS in terms of effectiveness and superior to ISBCS in terms of cost-effectiveness. Methods/design Multicenter non-inferiority randomised controlled clinical trial. Patients (18 years or older) with bilateral cataract and an indication for bilateral cataract surgery with an expected uncomplicated intraoperative and postoperative course are included in the study. Patients are randomly assigned to either ISBCS or DSBCS. The primary endpoint is the proportion of patients with a refractive outcome in the second eye within 1.0 dioptre from the target refraction, at 4 weeks after surgery. Secondary outcomes include corrected and uncorrected distance visual acuity, complications, patient reported outcomes (PROMs), cost-effectiveness, and budget impact. Follow-up visits are planned at 1 week after first-eye surgery and 4 weeks after second-eye surgery. At 3 months after first-eye surgery, the occurrence of complications is checked and patients fill in a final questionnaire. Discussion This study protocol describes the design of a multicenter non-inferiority randomised controlled trial. Current studies on ISBCS often lack information on safety regarding refractive outcomes. In addition, there is a lack of well-designed cost-effectiveness studies using established methods. The BICAT-NL study will provide more insight in refractive and cost-effectiveness outcomes for ISBCS compared to DSBCS. Trial registration This study was prospectively registered at Clinicaltrials.gov on January 17th 2018. (Identifier: NCT03400124.

Abstract
Background Reducing refractive error has always been a tricky problem. The aim of this study was to verify the correlation between binocular refractive error (RE) after sequential cataract surgery and explore an individualized calculation method of intraocular lens (IOL) for the second eye. Methods This was a prospective study. One hundred eighty-eight affected eyes in 94 age-related cataract patients who underwent sequential cataract surgery in the Department of Ophthalmology, Tangdu Hospital, China, were recruited. Complete case data were included for a correlation analysis of binocular RE. Data obtained in patients with RE values greater than 0.50 diopters (D) in the first eye were extracted and the patients divided randomly into two groups: Group A and B. In the adjustment group, group A, we modified the IOL power for the second eyes as 50% of the RE of the first eye. In group B, the control group, there was no modification. The mean absolute refractive error (MARE) values of the second eyes were evaluated one month after surgery. Results The correlation coefficient of the binocular RE after sequential cataract surgery was 0.760 (P < 0.001). After the IOL power of the second eyes was adjusted, the MARE of the second eyes was 0.57 ± 0.41 D, while the MARE of the first eyes was 1.18 ± 0.85 D, and the difference was statistically significant (P < 0.001). Conclusions Binocular REs were positively correlated after sequential cataract surgery. The RE of the second eye can be reduced by adjusting the IOL power based on 50% of the postoperative RE of the first eye.

A survey exploring ophthalmologists' attitudes and beliefs in performing Immediately Sequential Bilateral Cataract Surgery in the United Kingdom. BMC Ophthalmol 2020; 20:210. [PMID: 32487105 PMCID: PMC7265252 DOI: 10.1186/s12886-020-01475-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Accepted: 05/19/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The standard approach to treat cataracts is Delayed Sequential Bilateral Cataract Surgery (DSBCS), during which patients have a separate operation date for each eye. An alternative method of delivery is Immediately Sequential Bilateral Cataract Surgery (ISBCS). The aim of this project was to examine the attitudes and beliefs of UK ophthalmologists towards ISBCS, explore their reasons to either practise or not practise ISBCS and identify barriers hindering its implementation in the UK. METHODS A questionnaire was distributed to consultant members of The Royal College of Ophthalmologists (RCOphth, UK) and collected electronically. An initial screening question in regards to prior experience with ISBCS directed the rest of the survey; participants were asked to rate the importance of several factors with regards to performing ISBCS. Free text options were also available. Descriptive analysis was subsequently performed. RESULTS Of the 1357 recipients, 130 (9.6%) ophthalmologists completed the survey. Of those, 13.9% were currently performing ISBCS, 83.1% had never performed, and 3.1% had previously done so but since stopped. The main factors that acted as barriers were lack of: (1) College approval (20.5%); (2) medico-legal approval (20.2%); (3) evidence to support the use of ISBCS (16.0%); and (4) hospital approval (13.3%). Additionally, the perceived risk of complications for patients played an important role when considering ISBCS, with the risk of endophthalmitis being most feared. CONCLUSIONS This survey demonstrates some of the barriers that prevent ophthalmologist's performing ISBCS in the UK. There is a need for further exploration in this field to evaluate the effect of addressing any of these concerns on the implementation of ISBCS.
