Pseudo second anterior lens capsule during post-vitrectomy cataract surgery: A case report

After previous pars plana vitrectomy with silicone oil tamponade for retinal detachment, we're proud to announce the unexpected discovery of a membrane resembling a second anterior lens capsule during cataract surgery. Observations: A 26-year-old male with a history of two retinal detachment surgeries of the right eye over a 5-month period was met with reduced vision. The first retinal detachment repair was carried out with a 23-gauge PPV, followed by a 25-gauge PPV, scleral buckle, and silicone oil placement. Slit lamp examination and a nuclear cataract were found on presentation, and silicone oil migration to the anterior chamber appeared. With an intraocular lens implant of the right eye, it was decided that we would perform combined silicone oil removal and cataract extraction. This case illustrates the unusual finding of a membrane that behaved as a second anterior lens capsule intraoperatively and that contained novel pathology markers.

Outcome of cataract surgery with 1 h of preoperative antibiotic regimen: A strategy during COVID-19 Pandemic: Study from a tertiary eye care hospital

This study aims to report the visual and surgical outcomes of 810 eyes of 805 patients who underwent unilateral cataract surgery on the same day as 1 h of preoperative antibiotic therapy. This review consisted of a series of consecutive adult patients who underwent preoperative cataract surgery, received 1 h of preoperative antibiotic therapy, and underwent cataract surgery on the same day of consultation with a minimum 3-week follow-up period. 0. 3 LogMAR and 0. 07 0. 3 LogMAR, respectively, on PO day 1 and PO 3 weeks of the study group. B1 0. 3 LogMAR and 0. 07 0. 3 LogMAR BCVA's preoperative comparison of both POD 1 day and PO 3-week showed statistically significant improvement. Conclusion: Our study findings met the World Health Organization's definition of PO BCVA with positive surgical success.

Comparison between the effects of acetaminophen, dexmedetomidine, and normal saline infusion on pain severity after cataract surgery

Dexmedetomidine and acetaminophen infusion and normal saline alone, in comparison to the control group's findings on the severity of pain in cataract surgery, this study evaluated the risks of analgesia in other circumstances. Methods and methods: The effects of dexmedetomidine or acetaminophen infusion and NS on pain, vital signs, recovery rate, and surgeon satisfaction following cataract surgery were investigated in this parallel randomized controlled clinical trial. Patients receiving dexmedetomidine had a higher risk of respiratory depression. Both heart rate and oxygen saturation percentages showed no significant differences in the three groups, as well as pain severity. Conclusions: Acetaminophen was as safe as dexmedetomidine with lower side effects and greater surgeons' satisfaction, without any interference with cardiovascular or respiratory measurements. Acetaminophen infusion should be considered as a safe analgesic agent for cataract surgery.

Intensity simulation of photic effects after cataract surgery for off-axis light sources.

After cataract surgery, photopsia is a photic condition that can be related to intraocular lenses. Photopsia was simulated using the ZEMAX optical design software to determine the relative light intensity of photic effects observed after cataract surgery at the foveal region as the most vulnerable area of the retina. The hydrophilic IOLs embedded in the eye model have a capacity of 21 diopter with an optic diameter of 6 mm and 7 mm. The light intensity was detected at detectors located on the fovea, nasal side of the retina, or the IOLs' edge surface, depending on the angle of incident ray angle. The range in which the light intensity is detected on the fovea can be changed by changing the IOLs edge style to a completely reflective or anti-reflective surface. Patients' photic experiences will therefore be less traumatic for patients, according to an absorbing edge system.

Ocular biometric changes following unilateral cataract surgery in children.

Between the pseudophakic eyes and the fellow phakic eyes, there was a dramatic shift, axial growth, and corneal curvature changes. U00b1 2. 10 D and -0. 45 D/year in the phakic eyes increased during 7. 81 u00b1 4. 39 years, while the rate of myopic shift and initiation were higher at 3. 3 ad and -0. 45 in the corresponding phakic eyes. In the pseudophakic eyes, the pseudophakic eyes had a significantly higher rate of myopic shift in the pseudophakic eyes than in the phakic eyes. Conclusion In the pseudophakic eyes compared to those in groups under 6 years old, following unilateral cataract surgery, a significant postoperative myopic shift was evident in the pseudophakic eyes. When choosing the right strength of IOL in young children requiring unilateral cataract surgery, consider surgical myopic shift and the resulting anisometropia.

Comparison of Efficacy between Non-Steroidal Anti-Inflammatory Drugs and Anti-Vascular Endothelial Growth Factor in Preventing Macular Edema after Cataract Surgery in Diabetic Patients

Background: There is no agreement on the right way to prevent macular edema after cataract surgery in diabetic patients. The aim of the research is to determine the safety of topical nonsteroidal anti-inflammatory drugs and intravitreal injections of anti-VEGFs in diabetic patients without pre-existing macular edema. Conclusions: Our study found that topical NSAIDs eye drops, as well as cataract surgery in diabetic patients, is an effective prevention tool for macular edema.

Cataract Surgery Performed by High Frequency LDV Z8 Femtosecond Laser: Safety, Efficacy, and Its Physical Properties

Background: Our goal was to investigate the safety and effectiveness of the LDV Z8 femtosecond laser in cataract surgery relative to the common procedure. This prospective research was conducted at the Swiss Eye Research Foundation, Eye Clinic ORASIS, Reinach, Switzerland, in Reinach, Switzerland. Methods: This prospective study was conducted by the Swiss Eye Research Foundation, Eye Clinic ORASIS, Switzerland. The FEMTO LDV Z8 femtosecond laser system, which uses a new, low-energy, high repetition rate laser procedure for cataract surgery, was used to achieve capsulotomy and lens fragmentation in the laser group. Conclusions: The FEMTO LDV Z8 system was distinguished by complete and reproducible capsulotomy, as well as highly fragmented lens fragmentation.

Simultaneously Monitoring Whole Corneal Injury with Corneal Optical Density and Thickness in Patients Undergoing Cataract Surgery

This research was designed to monitor corneal wound injury after cataract surgery with a novel technique, in an attempt to ensure the least corneal involvement during cataract surgery. Two weeks before and one month after cataract surgery, a prospective cohort trial included thirty-two patients, who were assessed by a Scheimpflug tomography AxL u00ae using the following two indices: whole corneal optical density and corneal thickness. Regarding annuli 0. 0u20132. 0 mm, 2. 0 mm, and 6. 0 mm, no correlation was found at the surgical site, nor did we investigate the differences between COD and CT between pre- and post-operation, finding significant correlations between the delta of COD and the delta of CT.

Relationship between Cataract Surgery and Mortality in Elderly Patients with Cataract: Nationwide Population-Based Cohort Study in South Korea

Using the Korean National Health Insurance Service-Senior cohort database, we hoped to investigate the relationship between cataract surgery and all-cause and cause-specific mortality in Korean elderly patients with cataract. To determine the correlation between cataract surgery and mortality, we used Adjusted Cox regression models with time-varying covariates for cataract surgery. Patients with cataract surgery, women with lower income, those with lower income, and those without glaucoma had the highest mortality reductions in mortality risks as a result of cataract surgery.

Meta-analysis of the effects of femtosecond laser-assisted cataract surgery on corneal endothelial cells

P=0. 001]; the amount of postoperative corneal edema in both the FLACS and the CUCS group was significantly higher than that in the CUCS group at 1wk after the surgery [WMD=121. 76, 95%CI; P=0. 001]; P=0. 009]; P=0. 001; WMD=91. 84, 95%CI, P=0. 001]; P=0. 001]; the incidence of postoperative corneal e CONCLUSION: There were no differences between the two groups in terms of hexagonal cell count and coefficient of variation of corneal endothelial cells, and did not change the number of hexagonal cells and the length of the phacoemulsification process, and dramatically reduced the loss of corneal endothelial cells in the early postoperative period, as well as minimizing the incidence of postoperative corneal edema.
