Effectiveness and safety of early lens extraction during par plana vitrectomy for proliferative diabetes retinopathy with mild cataract:a randomized clinical trial

●AIM:To evaluate the effectiveness and safety of early lens extraction during pars plana vitrectomy(PPV)for proliferative diabetic retinopathy(PDR)compared to those of PPV with subsequent cataract surgery.●METHODS:This multicenter randomized controlled trial was conducted in three Chinese hospitals on patients with PDR,aged>45y,with mild cataracts.The participants were randomly assigned to the combined(PPV combined with simultaneously cataract surgery,i.e.,phacovitrectomy)or subsequent(PPV with subsequent cataract surgery 6mo later)group and followed up for 12mo.The primary outcome was the change in best-corrected visual acuity(BCVA)from baseline to 6mo,and the secondary outcomes included complication rates and medical expenses.●RESULTS:In total,129 patients with PDR were recruited and equally randomized(66 and 63 in the combined and subsequent groups respectively).The change in BCVA in the combined group[mean,36.90 letters;95%confidence interval(CI),30.35–43.45]was significantly better(adjusted difference,16.43;95%CI,8.77–24.08;P<0.001)than in the subsequent group(mean,22.40 letters;95%CI,15.55–29.24)6mo after the PPV,with no significant difference between the two groups at 12mo.The overall surgical risk of two sequential surgeries was significantly higher than that of the combined surgery for neovascular glaucoma(17.65%vs 3.77%,P=0.005).No significant differences were found in the photocoagulation spots,surgical time,and economic expenses between two groups.In the subsequent group,the duration of work incapacity(22.54±9.11d)was significantly longer(P<0.001)than that of the combined group(12.44±6.48d).●CONCLUSION:PDR patients aged over 45y with mild cataract can also benefit from early lens extraction during PPV with gratifying effectiveness,safety and convenience,compared to sequential surgeries.

Analysis of Ultrasonic Emulsification Surgery and Small Incision Cataract Extracapsular Extraction Surgery for Cataract Clinical Treatment Level Improvement

Objective:To analyze the efficacy of ultrasonic emulsification and small incision cataract extracapsular extraction in cataract patients.Methods:96 cataract patients admitted from May 2021 to May 2023 were selected and randomly grouped into group A(ultrasonic emulsification)and group B(small-incision extracapsular cataract extraction),with 48 cases each.Results:At 1 week,1-month,and 3 months post-operation,the visual acuity of group A was higher and the astigmatism value was lower than that of group B(P<0.05);at 12h,24h,and 48h post-operation,the intraocular pressure of group A was higher than that of group B(P<0.05);the thickness of macular area of group A was lower than that of group B at 1 week and 1-month post-operation(P<0.05).Conclusion:Ultrasonic emulsification in cataract patients was slightly better than small incision cataract extracapsular extraction in correcting astigmatism,improving visual acuity,and regulating macular thickness.However,due to the high energy of ultrasonic emulsification,the risk of complications such as high postoperative intraocular pressure was higher.Small-incision extracapsular cataract extraction has better application value in economically disadvantaged areas.

Efficacy of combined cataract extraction and endoscopic cyclophotocoagulation for the reduction of intraocular pressure and medication burden

AIM： To report on the efficacy of combined endoscopic cyclophotocoagulation（ECP） and phacoemulsification cataract extraction（PCE） with intraocular lens placement for reduction of intraocular pressure（IOP） and medication burden in glaucoma.·METHODS： A retrospective case review of 91 eyes（73patients） with glaucoma and cataract that underwent combined PCE/ECP surgery was performed. Baseline demographic and ocular characteristics were recorded,as well as intraocular pressure, number of glaucoma medications, and visual acuity postoperatively with 12-month follow-up. Treatment failure was defined as less than 20% reduction in IOP from baseline on two consecutive visits（at 1, 3, 6, or 12 mo postoperatively）,IOP ≥21 mm Hg or ≤5 mm Hg on two consecutive visits, or additional glaucoma surgery performed within12 mo after PCE/ECP.·RESULTS： Overall, mean medicated IOP was reduced from 16.65 mm Hg at baseline to 13.38 mm Hg at 12mo（P 0.0001）. Mean number of glaucoma medications was reduced from 1.88 medications at baseline to 1.48 medications at 12mo（P =0.0003）. At 3mo postoperatively,the success rate was 73.6%（95%CI： 63.3, 81.5）, 57.1% at6mo（95% CI： 46.3, 66.6）, and 49.7% at 12mo（95% CI：38.9, 59.6）. Patient demographic characteristics were not associated with treatment success. The only ocular characteristic associated with treatment success was a higher baseline IOP.· CONCLUSION： Combined PCE/ECP surgery is an effective surgical option for the reduction of IOP and medication burden in glaucoma patients. Patients withhigher baseline IOP levels are most likely to benefit from this procedure.

Inhibitory Effect of Short-Term Palpebral Margin Cleaning with Antibiotic Eye Drops on Ocular Surface Flora before Cataract Extraction:A New Preoperative Antibacterial Method

Objective To explore the clinical significance of the combined application of palpebral margin cleaning and antibiotic eye drops in inhibiting bacterial growth in the palpebral margin and conjunctival sacs before cataract extraction.Methods In this study,61 patients(97 eyes)with age-related cataract who underwent phacoemulsification and intraocular lens implantation were selected,and randomly grouped.In the experimental group,the combined application of palpebral margin cleaning with cotton pads and levofloxacin eye drops was given for three days before the surgery.In the control group,levofloxacin eye drops alone were applied for three consecutive days.Bacteria samples from the conjunctival sac and eyelid margins were cultivated and identified before and three days after taking antimicrobial measures,respectively.Results In the experimental group,the positive rates of the two bacteria samples were 100%(50/50)and 40%(20/50)before and 10%(5/50)and 0%(0/50)after the treatment.In the control group,the positive rates of the two bacteria samples were 97.9%(46/47)and 29.8%(14/47)before and 40.4%(19/47)and 10.6%(5/47)after the treatment.The positive rates between the two groups were not significantly different before taking antimicrobial measures(P=0.485 and 0.395),while they were significantly different after taking antimicrobial measures(P=0.001 and 0.024).Conclusion Combined application of eyelid and palpebral margin cleaning with cotton pads and antibiotic eye drops before cataract extraction imparted excellent antibacterial effects.

Liquefaction for cataract extraction

A systematic review of the recent literature regarding the implementation of the liquefaction in cataract surgery and its short-term and long-term outcomes in various parameters that affect the quality of patients＂ life, including visual rehabilitation and possible complications was performed based on the PubMed, Medline, Nature and the American Academy of Ophthalmology databases in November 2013 and data from 14 comparative studies were included in this narrative review. Liquefaction is an innovative technology for cataract extraction that uses micropulses of balanced salt solution to liquefy the lens nucleus. Most studies reported that liquefaction is a reliable technology for mild to moderate cataracts, while fragmentation difficulties may be encountered with harder nuclei.

Graft survival and visual outcome after simultaneous penetrating keratoplasty and cataract extraction

AIM: To evaluate the indications, complications, and visual and graft survival outcomes in eyes that had undergone simultaneous cataract extraction and penetrating keratoplasty (PKP). ·METHODS: We described a retrospective study of 101 patients who had undergone simultaneous cataract extraction and PKP at King Khaled Eye Specialist Hospital between January 1, 2001, and December 31, 2002. All patients were followed up postoperatively with maximum follow-up 68 months. ·RESULTS: The mean age of patients was 61 years. The mean overall follow -up was 27 months. The most common indications for surgery were corneal scarring (45.5% ), previous failed graft (15.8% ), corneal ulcer (12.9% ), Fuchs endothelial dystrophy (8.9% ), stromal dystrophy (2.9% ), and other conditions (14.5% ). Overall, 69 grafts (68.3% ) remained clear at final follow -up. Previous glaucoma or postoperative glaucoma had no statistically significant effects on graft outcome (P 】0.05). The graft rejection rate (17.8% ) was a significant risk factor for failure (P =0.00). Age, gender, indications for surgery, corneal graft diameter, and intraoperative vitreous loss had no statistically significant effects on the PKP outcome (P 】0.05). Postoperative visual acuity was significantly associated with preoperative visual acuity (P 【0.01). ·CONCLUSION: The present study provides evidence that performing a combined procedure results in more rapid visual rehabilitation and good graft clarity.

More than 10 Years of Experience with Immediate Sequential Bilateral Cataract Extraction (ISBCE)--A Retrospective Study

Background: To evaluate the safety of immediate sequential bilateral cataract extraction (ISBCE) with respect to indications, visual outcomes, complications, benefits and disadvantages. Methods: This is a retrospective review of all ISBCEs performed at Kantonsspital Winterthur, Switzerland, between April 2000 and September 2013. The case notes of 500 eyes of 250 patients were reviewed. Of these 500 eyes, 472 (94.4%) had a straight forward phacoemulsification with posterior chamber intraocular lens implantation;21 (4.2%) had a planned extracapsular cataract extraction;4 (0.8%) had an intracapsular cataract extraction and 3 (0.6%) had a combined phacoemulsification with trabeculectomy. Results: Over 66% of eyes achieved improved visual acuity (at least 3 Snellen lines) following ISBCE. Median preoperative best corrected visual acuity (BCVA) was 0.5 LogMAR;the interquartile range was [0.4, 1] LogMAR. At one week control the median BCVA was 0.3 LogMAR, IQR [0.1, 0.5] LogMAR. At one month the median BCVA was 0.15 LogMAR, IQR [0.05, 0.3] (p < 0.01). There were no sight-threatening intraoperative or postoperative complications observed. Conclusions: ISBCE is an effective and safe option with high degree of patient satisfaction. The relative benefits of ISBCE should be balanced against the theoretically enhanced risks.

A Clinical Analysis of 120 Cases with Traumatic Cataract Treated by Extracapsular Cataract Extraction and Posterior Chamber Intraocular Lens Implantation

Extracapsular cataract extraction was performed combined with posterior chamber intraocular lens implantation on 120 inpatients (122 eyes) with traumatic cataract from 1992 to 1997. The results revealed that this combined operation can make most of them get useful visual acuity, although they were often accompanied with several comlicated eye injuries. We think the most important thing is to choose suitable opertion time, the reasonable operation method and take close followup after operation.

Self-management of cataract extraction among diabetes patients

Background:Diabetes-related cataract extraction is a minor surgery required to regain full vision.One of the recognized factors that can delay or prevent full-vision recovery is poor management,and most of this management is being carried out by patients themselves.Objective:This study aimed to assess the knowledge of diabetes patients on self-management after cataract extraction in two tertiary hospitals in Osun State.Methods:A cross-sectional descriptive design was conducted among 97 diabetes patients who underwent cataract extraction and were attending clinics and follow-up visits in Osun State.A self-structured questionnaire was used for data collection.Results:Moderate knowledge was found among the participants on an appropriate diet(56.7%),prevention of injury risk(57.5%),prevention of infection risk(50.9%),and low knowledge on the technique of administration of eye drop(60.8%)after cataract extraction,whereas 74.7%of the total respondents were knowledgeable on the indication for follow-up visit after cataract extraction,these results were found to be below the expected knowledge level.Conclusion:An intensive and comprehensive educational initiative by nurses should be tailored to meet the specific needs of diabetes patients with cataract surgery.Nurses also need to implement the use of checklist which will enhance learning and improve patient understanding of self-management after cataract extraction.

Inhibitory Effects of Grape Seed Proanthocyanidin Extract on Selenite-induced Cataract Formation and Possible Mechanism

This study investigated the inhibitory effect of grape seed proanthocyanidin extract(GSPE) on selenite-induced cataract formation in rats and the possible mechanism.Eighty 8-day-old Sprague-Dawley rats were divided randomly into 5 groups:control group,model group,three GSPE groups(low dose,medium dose and high dose).Control group received subcutaneous injection of physiological saline.Model group was given subcutaneous injection of sodium selenite(20 μmol/kg body weight) on the postpartum day 10,and once every other day for consecutive three times thereafter.GSPE treated groups were respectively administered GSPE at doses of 50,100,and 200 mg/kg body weight intragastrically 2 days prior to the selenite injection(that was,on the postpartum day 8),and once daily for fourteen consecutive days thereafter.The opacity of lenses was observed,graded and photographed under the slit lamp microscopy and the maximal diameter of the nuclear cataract plaques was measured.The lenses were analyzed for superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-PX),malondialdehyde(MDA),calcium(Ca 2+),nitric oxide(NO) and anti-hydroxyl radical ability(anti-OH).The histomorphology of lenses was observed with HE staining under a light microscope.The levels of calpainⅡ,and iNOS protein and mRNA expression in lenses were detected by using immunohistochemistry and real-time quantitative RT-PCR.The results showed subcutaneous injection of sodium selenite led to severe nuclear cataract in model group,and the achievement ratio of model group was 100%.As compared with model group,the degree of lenses opacity and the maximal diameter of nuclear cataract plaques were significantly reduced in GSPE-treated groups.Moreover,we observed selenite treatment caused a significant decrease in the activities of antioxidative enzymes(SOD,CAT,GSH-PX) and anti-OH ability,accompanied by a significant increase in the levels of MDA,NO,Ca 2+ as well as iNOS,and calpainⅡ protein and mRNA expression.Administration of GSPE could dose-dependently preserve the activities of these antioxidative enzymes and anti-OH ability,accompanied by a significant reduction in the levels of MDA,NO,Ca 2+ as well as iNOS,and calpainⅡ protein and mRNA expression.These results suggested that GSPE markedly prevented selenite-induced cataract formation probably by suppressing the generation of lipid peroxidation and free radicals as well as the activation of iNOS,and calpainⅡ in the lenses.
