Tang YF, Duan ZH. Clinical efficacy of femtosecond laser-assisted phacoemulsification in diabetic cataract patients. World J Clin Cases 2024; 12:1733-1741. [PMID: 38660074 PMCID: PMC11036478 DOI: 10.12998/wjcc.v12.i10.1733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 02/25/2024] [Accepted: 03/08/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND Diabetic patients with cataracts encounter specific difficulties during cataract surgery due to alterations in microcirculation, blood supply, metabolism, and the microenvironment. Traditional phacoemulsification may not fully tackle these issues, especially in instances with substantial preoperative astigmatism. The utilization of femtosecond laser-assisted phacoemulsification, in conjunction with Toric intraocular lens (IOL) implantation, offers a potentially more efficient strategy. This research seeks to evaluate the efficacy and possible complications of this approach in diabetic cataract patients.
AIM To investigate the clinical efficacy and complications of femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation in diabetic cataract patients, comparing it with traditional phacoemulsification methods.
METHODS This retrospective study enrolled 120 patients with diabetes cataract from May 2019 to May 2021. The patients were divided into two groups: the control group underwent traditional phacoemulsification and Toric IOL implantation, while the treatment group received Len Sx femtosecond laser-assisted treatment. Outcome measures included naked eye vision, astigmatism, high-level ocular phase difference detection, clinical efficacy, and complication.
RESULTS There were no significant preoperative differences in astigmatism or naked eyesight between the two groups. However, postoperative improvements were observed in both groups, with the treatment group showing greater enhancements in naked eye vision and astigmatism six months after the procedure. High-level corneal phase difference tests also indicated significant differences in favor of the treatment group.
CONCLUSION This study suggests that femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation appears to be more effective in enhancing postoperative vision in diabetic cataract patients compared to traditional methods offering valuable insights for clinical practice.

Abstract
PURPOSE To analyse the long anatomical and functional outcome of a subgroup of the DICAT II study cohort, consisting of 26 patients undergoing cataract surgery and withdrawn from the study for a clinically significant worsening of early diabetic macular edema (DME). MATERIALS Patients who underwent cataract surgery and withdrawn from the DICAT II study for a clinically significant worsening of early DME with at least 12 months follow-up after the dropout. The study population was divided into two groups according to the clinical evaluation at one-year follow-up: ongoing treatment patients for DME (Treatment group, TG) and patients no longer treated (Non Treatment group, NTG). RESULTS Central foveal thickness (CFT) at baseline and dropout time were higher in TG than in the NTG, with a statistically significant difference (p < 0.05). In addition, TG patients reported a higher levels of glycated hemoglobin at time baseline compared to NTG patients (7.81 ± 1.15 vs 7.02 ± 0.56; p = 0.048). The linear regression analysis demonstrated a statistically significant relationship between the visual acuity and the ongoing treatment group at one-year follow-up (p = 0.042). CONCLUSION The study provides parameters to be considered when assessing the risk of developing persistent DME after cataract surgery in diabetic patients. In particular, CFT at baseline and dropout time have been reported to be an effective and predictable OCT biomarkers when evaluating DME progression. During the evaluation of the systemic disease, similar results were found for the glycated hemoglobin at baseline.

Abstract
Diabetic macular edema (DME)'s therapeutic approach can frequently be challenging. The purpose of the review is to propose evidence-based recommendations on the employment of intravitreal dexamethasone implants (DEX) when approaching patients suffering from DME. Seven national consensuses redacted by different groups of retina specialists from Europe and Asia were examined and confronted. Each consensus was redacted utilizing a Delphi approach, in person meetings, or by reviewing the literature. DEX can be studied as a first-line strategy in individuals suffering from DME with inflammatory OCT biomarkers, in vitrectomized eyes, in patients with recent cardiovascular events, in pregnant women, in patients scheduled to undergo cataract surgery or with poor compliance. The other parameters considered were the indications to the DME treatment, when to switch to DEX, the definition of non-responder to anti-VEGFs agents and to the DEX implant, whether to combine DEX with laser photocoagulation, the association between glaucoma and DEX, and the management of DEX and the cataract. Although several years have passed since the introduction of DEX implants in the DME treatment, there is still not a unified agreement among retina specialists. This paper compares the approach in the DME treatment between countries from different continents and provides a broader and worldwide perspective of the topic.

Abstract
BACKGROUND Patients with pre-existing macular edema (ME) due to diabetes and retinal vein occlusions (RVO) make up a growing population receiving cataract surgery. Surgery is associated with an increased risk of worsening existing ME due to post-surgical inflammation that can be further exacerbated by pre-existing diabetic retinopathy (DR) and retinal vein occlusion. This study aimed to examine the pre-operative use of intravitreal dexamethasone (DEX) implants in patients with ME undergoing cataract surgery. METHODS A retrospective study was conducted at National Cheng Kung University Hospital in Taiwan involving 19 eyes of 16 patients with DME or ME associated with RVO. All participants received a DEX implant at baseline and underwent phacoemulsification within 3 months after its insertion. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) and central subfield thickness (CST) were evaluated. RESULTS DEX implants reduced the CST from baseline (357.8 μm) to pre-surgery (280.8 μm). This reduction below baseline continued to month 6 post-surgery (319.4 μm). From baseline (16.15 mmHg), the mean IOP initially increased pre-surgery (17.78 mmHg) before returning to the baseline value at month 6 post-surgery (16.15 mmHg). All patients improved their BCVA from logMAR 0.943 on average at baseline to logMAR 0.532 at month 6 post-surgery. CONCLUSIONS The results of the study suggested that patients with ME could benefit from DEX implants before cataract surgery within 3 months to achieve sufficient postoperative inflammation management and limit ME deterioration. DEX implants did not increase IOP post-surgery and was similar to baseline levels.

Abstract
Diabetic macular edema (DME) causes visual impairment in diabetic retinopathy (DR). Diabetes mellitus is a global epidemic and diabetic individuals are at risk of developing DR. Approximately 1 in 10 diabetic patients suffers from DME, which is the commonest cause of vision-threatening DR at primary-care screening. Furthermore, diabetes predisposes to a higher frequency and a younger onset of cataract, which further threatens vision in DME patients. Although cataract extraction is an effective cure, vision may still deteriorate following cataract surgery due to DME progression or recurrence, of which the risks are significantly higher than for patients without concurrent or previous history of DME at the time of operation. The management of pre-existing DME with visually significant cataract is a clinical conundrum. Deferring cataract surgery until DME is adequately treated is not ideal because of prolonged visual impairment and maturation of cataract jeopardizing surgical safety and monitoring of DR. On the other hand, the progression or recurrence of DME following prompt cataract surgery is a profound disappointment for patients and ophthalmic surgeons who had high expectations for postoperative visual improvement. Prescription of perioperative anti-inflammatory eye drops is effective in lowering the risk of new-onset DME after cataract surgery. However, management of concurrent DME at the time of cataract surgery is much more challenging because DME is unlikely to resolve spontaneously even with the aid of anti-inflammatory non-steroidal or steroid eye drops. A number of clinical trials using intravitreal injection of corticosteroids and anti-vascular endothelial growth factor (anti-VEGF) as first-line therapy have demonstrated safety and efficacy to treat DME. These drugs have also been administered perioperatively for the prevention of DME worsening in patients undergoing cataract surgery. This article reviews the scientific evidence to guide ophthalmologists on the efficacy and safety of various therapies for managing patients with DME who are particularly vulnerable to cataract surgery-induced inflammation, which disintegrates the blood-retinal barrier and egression of fluid in macular edema.

Abstract
OBJECTIVE To compare outcomes of cataract surgery combined with either anti-Vascular Endothelial Growth Factor (anti-VEGF) therapy or dexamethasone implant (DEX) in patients with diabetic macular oedema (DMO). METHODS Pubmed and Embase databases were searched for studies reporting outcomes of diabetic cataract surgery combined with either anti-VEGF or DEX, with a follow-up ≥3 months. The primary outcome was the mean change in central macular thickness (CMT). Mean change in best corrected visual acuity (BCVA) was considered as a secondary outcome. The mean difference between baseline and post-treatment values (MD) with 95%-Confidence Interval (95%CI) was calculated and meta-analyses were performed. RESULTS Nine-teen studies were included, 8 in the DEX group and 11 in the anti-VEGF group. A significant reduction of macular thickness was shown in the DEX group at 3 months (MD = -98.35 µm; 95% CI, -147.15/-49.54), while mean CMT change was non-significant in the anti-VEGF group (MD = -21.61 µm; 95% CI, -59.46/16.24; test of group differences, P < 0.001). At 3 months, no difference in visual gain was found between the two groups (P = 0.13). CONCLUSIONS In DMO patients, cataract surgery combined with DEX seems to provide better anatomical outcomes compared with cataract surgery combined with anti-VEGF therapy. However, our evidence was limited by significant heterogeneity. Randomised trials comparing these two different combined approaches are warranted.

Abstract
Diabetic cataracts (DC) is one of the main causes of blindness among patients with diabetes mellitus. The aim of the present study was to examine the effect of simvastatin on lens epithelial cells in DC and the underlying mechanism. The viability of SRA01/04 cells treated with different concentrations of simvastatin was detected using a Cell Counting Kit-8 assay before and after high glucose (HG) treatment. The expression levels of E-cadherin, N-cadherin, Vimentin and α-smooth muscle actin (α-SMA), proteins associated with epithelial-mesenchymal transition (EMT), in addition to RhoA, Rho-associated kinases (ROCK)1 and ROCK2, proteins related to RhoA/ROCK signaling, were also measured in SRA01/04 cells treated with HG and simvastatin, with or without U46619, using western blot analysis. DCFH-DA dyes, superoxide dismutase (SOD) and glutathione (GSH)/glutathione disulfide (GSSG) kits were used to measure the levels of oxidative stress parameters in SRA01/04 cells treated with HG and simvastatin with or without U46619. The cell viability of SRA01/04 cells treated with simvastatin was found to be significantly elevated after HG treatment. The protein expression levels of E-cadherin were increased but those of N-cadherin, Vimentin and α-SMA decreased after HG and simvastatin treatment, and this was reversed by U46619. The levels of SOD and GSH-GSSG were found to be increased whereas reactive oxygen species levels were decreased, effects that were reversed by U46619. Additionally, the protein expression levels of RhoA, ROCK1 and ROCK2 were markedly decreased. These findings provided evidence that simvastatin increased HG-induced SRA01/04 cell viability and exerted inhibitory effects on EMT and oxidative stress that occurs during DC.

Abstract
Objective. The purpose was to explore the effect of cataract surgery on postoperative macular edema and visual acuity in patients with diabetic retinopathy. Methods. 88 patients with diabetic retinopathy treated in our hospital (December 2019–December 2020) were chosen as research subjects and divided into experimental group of 44 patients (52 eyes) and control group of 44 patients (54 eyes) according to the odd and even admission numbers. The control group received laser photocoagulation treatment, while the experimental group underwent cataract surgery. The central macular thickness (CMT) and visual acuity of the two groups after treatment were detected to evaluate the therapeutic effect of different treatment methods on diabetic retinopathy. Results. No obvious differences in sex ratio, average age, average course of disease, average weight, average BMI, average glycosylated hemoglobin, and residence were found between the two groups
. The total clinical effective rate in the experimental group was obviously higher compared with the control group
. The CMT at T1, T2, and T3 in the experimental group was obviously lower compared with the control group
. The BCVA in the experimental group at 1 month and 3 months after treatment was obviously higher compared with the control group
. The VEGF levels of both groups after treatment were obviously lower
, and the VEGF level in the experimental group after treatment was obviously lower compared with the control group
. The total incidence of complications in the experimental group was obviously lower compared with the control group
. Conclusion. Cataract surgery is a reliable method to improve visual acuity and reduce serum inflammatory indicators in patients with diabetic retinopathy, with better clinical effect than laser photocoagulation, which is recommended for the treatment of diabetic retinopathy.

Abstract
BACKGROUND The prospective DIabetes and CATaract Study II (DICAT II) was performed to characterise the risks of cataract surgery to the retinae of patients with early diabetic macular oedema (E-DMO). METHODS DICAT II was a prospective, comparative, multicentre, observational study involving six Italian clinics. Patients were aged ≥55 years, had type 1 or 2 diabetes with spectral-domain optical coherence tomography evidence of ESASO classification Early DMO. Group 1 eyes (78 eyes, 78 patients) underwent phacoemulsification-based cataract surgery. Group 2 eyes (65 eyes, 65 patients) had E-DMO and either clear media or had undergone uncomplicated cataract surgery ≥1 year previously. Central subfield thickness (CST) and best-corrected visual acuity (BCVA) were assessed in both groups. RESULTS The negative impact of surgery on CST was evident after the first postoperative week; CST peaked during the first month, then rapidly decreased. CST worsening ≥10 µm was observed in 63/78 eyes (80.7%) and 29/65 eyes (44.6%) in Groups 1 and 2, respectively (p < 0.0001). CST worsening of ≥50 µm was observed in 51 eyes (65.4%) and 10 eyes (15.4%) in Groups 1 and 2, respectively (p < 0.0001). Mean CST worsening was lower in Group 2 than in Group 1 (38.6 ± 30.4 µm vs 85.5 ± 55.3 µm, p < 0.0001) with a lower BCVA loss (-2.6 ± 3.5 letters vs -8.2 ± 6.2 letters, p < 0.0001). Higher glycaemic levels and HBA1c levels were significantly associated with the risk of >50 μm CST worsening in eyes from both groups. CONCLUSION Early DMO is associated with poorer outcomes after cataract surgery and requires close pre- and postoperative monitoring.

Abstract
Purpose To estimate the incidence of central macular edema (CME) following cataract surgery and to correlate the central macular thickness (CMT) to the best-corrected visual acuity (BCVA). Methods This cohort study in 2018-2019 included cataract grades I and II. They were operated by phacoemulsification and intraocular lens implantation. CMT was measured using spectral-domain optical coherence tomogram (OCT) before and for three months at one-month intervals after surgery. The change in BCVA and CMT were correlated at three months after surgery. Incidence of CME (more than two SD of pre-surgery CMT) was calculated. Results The mean CMT for 138 eyes operated for cataracts measured before and at one, two, and three months after uneventful surgery was 213 ± 24.9, 222.7 ± 25.5, 217.8 ± 34.8, and 215 ± 28.3 µ, respectively. The median BCVA at three follow-ups was 0.2 (interquartile range [IQR] 0.1; 0.2), 0.1 (IQR 0.0; 0.1), and 0.0 (0.0; 0.03), respectively. The incidence of CME at one and three months was 18% and 4.3%, respectively. The CMT and VA (LogMAR) one month after cataract surgery were significantly correlated (r = 0.4, Pearson P < 0.001). The visual improvement between one and two months post-surgery was not significantly correlated with CMT decline (r = 0.06, Pearson P = 0.5). The BCVA at one, two, and three months was 0.0 LogMAR in 28 (20.3%), 52 (37.7%), and 104 (75.4%) eyes, respectively. Linear regression model, age and diabetes are the risk factors at one month. At two and three months, no significant risk factors were found. Conclusion CME post-cataract surgery seems to be transient. CMT changes correlate with best-corrected vision changes and seem to be affected by age and presence of diabetes in the 1st month after surgery.

Combined Intravitreal Dexamethasone Implant and Cataract Surgery in Patients with Diabetic Retinopathy: Effect on Retinal Morphology and Function. Adv Ther 2020; 37:4675-4684. [PMID: 32970316 PMCID: PMC7547947 DOI: 10.1007/s12325-020-01506-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 09/14/2020] [Indexed: 01/30/2023]
Abstract
Introduction Cataract surgery can be associated with vision-threatening complications in patients with diabetes. This study aimed to assess the functional and anatomic outcomes of the intravitreal dexamethasone (DEX) implant, administered at the time as cataract surgery, in patients with diabetic retinopathy and diabetic macular edema (DME). Methods This was a retrospective, observational, and single-center study. The primary endpoint was the mean change in central macular thickness (CMT) from baseline to month 1. Secondary endpoints included mean change in best corrected visual acuity (BCVA) from baseline to month 1 and 3, mean change in CMT from baseline to month 3, the photopic negative response (PhNR) and the b wave of flash full-field electroretinogram from baseline to month 1, and the incidence of adverse events. Results Twenty-four eyes of 21 patients were included in the study. The mean (range) age of patients was 69 (63–87) years and 13 (61.9%) were men. Mean (standard deviation) CMT significantly decreased from 447 (134) µm at baseline to 341 (134) µm at month 1 (mean difference − 106 ± 134 µm, 95% CI − 183.9 to − 28.1 µm; p = 0.0087). BCVA significantly improved from 46 (20) ETDRS letters at baseline to 59 (22) ETDRS letters at month 1 (mean difference 13 ± 21 letters, 95% CI 0.8–25.2 letters; p = 0.0375). Regarding electrophysiology, there was a statistically significant reduction in mean PhNR from 5.24 (1.67) µV at baseline to 3.73 (1.19) µV at month 1 (mean difference − 1.51 ± 0.42 µV, 95% CI − 2.4 to − 0.7 µV, p = 0.0008); whereas b wave amplitude did not change (12.69 ± 6.89 µV at baseline versus 12.29 ± 6.30 µV at month 1; p = 0.8347). Four (16.7%) eyes developed ocular hypertension over the course of follow-up, which was successfully controlled with topical hypotensive medication. Conclusion Perioperative DEX implant significantly improved both anatomic and functional outcomes in patients with DME who underwent cataract surgery.

Abstract
AIMS To compare the long-term functional and anatomical outcomes of cataract surgery with combined versus 1-month deferred intravitreal dexamethasone implant (DEX) in eyes with pre-existing diabetic macular edema (DME). METHODS Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were retrospectively evaluated in both groups before treatments, then 1, 4, 12 and 24 months after DEX. RESULTS Forty eyes were analyzed, 20 in each group. BCVA disclosed comparable trends, increasing from similar starting values (p = 0.9913) to akin scores 1 month after DEX (p = 0.4229). After 4 months, it similarly reduced without significant variations within each group throughout the whole observation period. CRT was similar at the time of surgery (p = 0.6134) and was reduced by DEX injection in both samples, with a superior beneficial effect in the combined group after 1 month (p = 0.0010). At 4 months, CRT further elevated and remained overall stable in the long term without differences. By 12 months, 19 (95%) eyes received further injections: 1 (5%) fluocinolone, 3 (15%) received other DEX and fluocinolone, 13 (65%) ≥ 1 DEX only and 2 (10%) anti-VEGFs. During the second year, 6 additional eyes (from the 13 receiving DEX) switched to fluocinolone, reaching a total of 10 (50%). Similar results were observed in the deferred group. CONCLUSIONS DEX implant performed at the time of surgery achieved the same long-term functional and anatomical outcomes compared to a 1-month injection deferral in treating eyes with pre-existing DME that should undergo cataract extraction.

Abstract
PURPOSE Intravitreal corticosteroid implants based on sustained-release dexamethasone provide effective retinal delivery of drug for around 6 months for the treatment of diabetic macular edema (DME). As current recommendations on the management of patients with DME undergoing cataract surgery are limited, this article aims to highlight issues and provide guidance on the use of dexamethasone intravitreal implants (DEX-DDS) in patients with DME undergoing cataract surgery, based on the consensus findings of a panel of Italian experts. METHODS The panel developed a survey regarding the use of DEX-DDS in patients with DME undergoing cataract surgery, following a comprehensive literature search. The results of the survey were discussed at an experts' meeting in September 2018, with a structured approach to determining consensus. The routine management of patients with DME undergoing cataract surgery was also developed for use as a basis of discussion to highlight current issues. RESULTS Eight consensus statements are presented, along with key issues that highlight controversial/outstanding issues in the use of DEX-DDS in DME patients with cataracts. CONCLUSION The consensus statements can help provide practical guidance for clinicians in daily practice on the rationale, patient diagnosis and selection, and optimal management of patients with DME undergoing cataract surgery.

Abstract
PURPOSE To report on the prevalence of diabetes, diabetic macula oedema (DME) and retinopathy and their respective grading in a large cohort of patients undergoing cataract surgery. METHODS Data on previous diagnosis of diabetes, fasting glucose, glycated haemoglobin, presence and type of retinopathy and other maculopathy of 3657 patients over 55 years of age undergoing cataract surgery in 13 centres scattered throughout Italy were analysed. RESULTS A total of 20.4% of patients were known diabetics and 27.9% of diabetics showed signs of retinopathy. Haemoglobin A1C was higher than 48 mmol/L (6.5%) in 32% of diabetics and 2.4% non-diabetics. Fasting blood glucose level was higher than 120 mg/dL in 4.3% non-diabetics and 50% diabetics. Duration of diabetes did not significantly correlate with either fasting glucose or glycated haemoglobin, while higher grades of diabetic retinopathy were significantly more prevalent as duration of disease increased. DME was present in almost 40% of diabetics and 22% of patients showed non-diabetic maculopathy. DISCUSSION Diabetic retinopathy and DME worsen after cataract extraction thus complicating long-term prognosis and requiring expensive injective therapy. Since unknown diabetics represent 2-4% of the many million cataract candidates and even known diabetics show poor metabolic control and high rates of DME, preoperative medical testing and accurate retinopathy screening may prove both ethically necessary and cost-effective.
