Analysis of antibiotic resistance and genetic profile of conjunctival bacteria flora before and after cataract surgery

Purpose: Objective Objectives: With the emphasis on coagulase-negative staphylococci during cataract surgery and addressing the implications of this colonization as a potential source of endophthalmitis, it was possible to analyze antibiotic resistance and genetic profile of conjunctival bacteria flora before and after cataract surgery. C 0 and 86. 4% in T 0 and 86 percent in C 0 respectively. Results The frequency of CNS was significantly reduced in T 1 from 81. 4% in T 0 to 86. 4% in C 0 from 86 percent. Epidermidis of S. epidermidis was the most common species isolated in any time period. In 7 patients 100% coincident with the seven alleles of the S. epidermidis isolated before to povine-iodine 5% disinfection and at the end of the surgery. As those isolates from C 0 or T 0, the same species, antibiotic, and virulence profile of T1 or T 2 isolates from T 1 or T 2 related to the same species, antibiotic, and virulence profile as those isolates from T 1 or T 0.

Massive intraocular hemorrhage, presumably from the central retinal artery after cataract surgery, and difficult hemostasis during vitrectomy: a case report

Background Severe intraocular hemorrhage is a rare complication of cataract surgery, and it is attributed to the recent widespreadization of minimal-incision cataract surgery. We present a case of a massive intraocular hemorrhage that seems to have arisen from the central retinal artery following cataract surgery, in which hemostasis was impossible to obtain during vitrectomy. After undergoing cataract surgery, an 86-year-old woman was referred to our center for intraocular lens dislocation. Bleeding dramatically reduced in the second surgery compared to the first. Following the second surgery, however, the patient's visual acuity showed no light perception after the second surgery. After undergoing cataract surgery, massive intraocular hemorrhage may have occurred from the central retinal artery. In these situations, surgery with general anesthesia with lower blood pressure may be suggested, considering the possibility of difficult hemostasis in the event of bleeding from the retinal artery.

Impact of Perioperative Dry Eye Treatment with Rebamipide Versus Artificial Tears on Visual Outcomes After Cataract Surgery in Japanese Population

Introduction The present study was designed to compare the effects of rebamipide and artificial tears during cataract surgery's perioperative period. From 4 weeks preoperatively to 3 months postoperatively, Rebamipide was delivered in one eye and Mytear’u00ae synthetic tear ophthalmic solution in the other eye. Mean TBUT was noticeably higher in group R than in group B at each assessment, while mean C-SPK and HOAs were significantly smaller in group R than in group B, though mean C-SPK and HOAs were much lower in group R than in group A. Mean CDVA was much higher in group R1 week and 1 month postoperatively than group A, compared to group A; this figure was not significant at 3 months. Conclusion In the perioperative period of cataract surgery with trifocal IOL implantation, dry eye management with rebamipide was significantly more effective than artificial tears in improving ocular surface condition, contrast sensitivity, and disability glare postoperatively, especially postoperatively.

Early DMO: a predictor of poor outcomes following cataract surgery in diabetic patients. The DICAT-II study

Introduction The prospective DIabetes and CATaract Study II was carried out to assess the risks of cataract surgery to patients with early diabetic macular oedema. E-DMO and either clear media or those who had undergone uncomplicated cataract surgery had been eyed by a G-2 nephropathy unit (u22651 year ago), according to E-DMO and either clear media or had undergone uncomplicated cataract surgery. u22651 years ago. CST's positive results after the first postoperative week were apparent after the first month, before slowly decreasing. CST worsened in eyes in Groups 1 and 2, respectively, with 63/78 eyes and 29/65 eyes visible in 63/78 eyes and 29/65 eyes. u00b5m CST worsened in eyes from both groups. te03bcm CST worsened in eyes.

Effect of cataract surgery on vision-related quality of life among cataract patients with high myopia: a prospective, case-control observational study

Objects: To determine the effect of cataract surgery on vision-related quality of life in cataract patients with high myopia. Methods In this prospective research, 90 patients with bilateral HM and 90 age-matched patients with normal axial lengths who underwent phacoemulsification surgery were sequentially included. Although the preoperative NEI-VFQ-25 composite score in the HM group was lower than in the control group's control group, the postoperative composite score in the HM group was not significantly different between the two groups; however, changes in composite score and scores of 7 subscales were higher in the HM group than in the control group; however, composite score and scores of 7 subscales were higher in the HM group than in the control group were not significantly different between the two groups; Patient age was negatively correlated with the change in composite score in the HM group but not in the control group. Conclusions: VR-QOL is significantly impaired in cataract patients with HM and is greatly enhanced by cataract surgery.

SMILE for the Treatment of Residual Refractive Error After Cataract Surgery

Introduction In the context of assessing patient's anticipation and satisfaction with cataract surgery's visual acuity, we investigated the rise in visual acuity and patient satisfaction after small-incision lenticule extraction in pseudophakic patients with residual myopic refraction following cataract surgery. Methods Seventy-six patients who underwent cataract surgery with ZEISS AT LISA tri 839MP IOL implantation were included in this retrospective review. We reviewed visual acuity and satisfaction, as well as laser vision enhancement and satisfaction in patients who were dissatisfied with trifocal IOL implantation. logMAR increased from 0. 65 u00b1 [0. 52] logMAR preoperatively to 0. 09 [0. 050. 1] logMAR at six months postoperatively, with 0. 09 [0. 05] u20130. 1] logMAR at 12 months postoperatively.

Prevalence and Characteristics of Dry Eye Disease After Cataract Surgery: A Systematic Review and Meta-Analysis

Dry eye disease following cataract surgery is linked to various risk factors, but it can cause a wide variety of heterogeneous signs, such as reduced quality of vision. After cataract surgery, 31. 4% of patients without pre-existing DED developed DED. DED after cataract surgery was caused by age, female sex, systemic diseases, psychobiological drugs, psychiatric disorders, pre-existing DED, meibomian gland dysfunction, preservatives in eye drops, surgery techniques, and lifestyle. Following cataract surgery, the DED severity peak occurred 1 day postoperatively and lasted for at least 1 month, so a consistent follow-up for at least 1 month after cataract surgery is warranted. Following cataract surgery, topical application of a preservative-free diquafosol tetrasodium solution and preoperative meibomian gland stimulation were both highly effective in preventing and treating DED. Following cataract surgery to increase satisfaction and vision quality, more than one-third of patients develop DED after cataract surgery.

Comparison of Three-Dimensional Surgical System Versus Binocular Microscope for Clear Corneal Incision in Cataract Surgery

Introduction In comparison between a three-dimensional visualization system and a traditional binocular microscope for phacoemulsification and intraocular lens implant surgery, we can examine surgical results of 2. 2 mm clear corneal incision between a three-dimensional visualization system and a traditional binocular microscope for phacoemulsification and intraocular lens implantation surgery. Methods In this randomized controlled clinical trial, 60 people with age-related cataracts were divided into two groups receiving cataract surgery, either a 3D vision system or a binocular microscope. The ECD loss rate in the 3D group was 8. 1% and 12. 3% in the BM group, but the difference was not statistically significant. Before and after surgery, there was no difference between the 3D group and the BM group in terms of other ocular or surgical parameters. Conclusions Using the 3D surgical system for phacoemulsification and IOL implantation surgery seems to produce similar ECD and CCI conditions as using a conventional binocular microscope.

Outcomes and complications of cataract surgery in patients with chronic ocular graft-versus-host-disease—a multicenter, retrospective analysis

After allogeneic hematopoietic stem cell transplantation, we need to determine the results of phacoemulsification in patients with chronic ocular Graft-versus-host disease. 104 eyes replaced cataract surgery in seventy-three patients. In n = 84 eyes, the oGVHD NIH grade was announced; 12% of the evaluated eyes were staged; NIH grade 1, 39% NIH is the highest in NIH; 39%, NIH grade 1,31%, 39% NIH3. After surgery without fear of oGVHD severity, logMAR increased from 0. 7 0. 6 to 0. 4 logMAR. Visual acuity was moderately related to pre-operative grade of corneal staining. With each rise of corneal staining by one grade, the visual acuity reduced by 0. 078 LogMar units. In 42 percent of the eyes, corneal epitheliopathy increased sharply after surgery. Conclusion: Phacoemulsification in patients with persistent oGVHD leads to significant visual acuity, but it is also associated with an elevated risk of complications, in particular corneal epitheliopathy and corneal perforations.
