Ropivacaine versus Bupivacaine-lidocaine Mixtures used in Peribulbar Blocks for Cataract Surgery: A Randomised, Triple-blind Clinical Study

Since both these anaesthetic agents were known to have cardiovascular and Central Nervous System side-effects, safer alternatives such as levobupivacaine and ropivacaine are being introduced into clinical use. Aim: To perform a comparative review of the morphology of peribulbar blocks with 0. 7 percent ropivacaine vis-u00e0-vis the commonly used bupivacaine plus lidocaine mixtures. Patients undergoing cataract surgery were divided into three groups of 30 patients. In group B, 6 mL of 0. 8 percent bupivacaine and 2% lidocaine, and 6 mL of 1:1 mixture of 0. 2 percent bupivacaine and 2% lidocaine were given, as well as 6 mL of 0. 8 percent ropivacaine with adrenaline. In group R, the total analgesic intake was 56. 3 percent, 75. 42 and 68. 3 percent, with patients of group R showing a significant decline in intake. Compared to other groups, there was a significant decrease in IOP in the patients of group R compared to other groups, and the differences between 5 minutes,10 minutes, and 25 minutes intervals were found to be statistically significant. Patients in groups R, BL and BLA, and group R's group, had less frequent burning sensation episodes, which was statistically significant. Patients and surgeons in groups R had higher satisfaction ratings than those in groups R. More patients and surgeons in groups R had higher satisfaction ratings.

Molecular and microbiological evidence of bacterial contamination of intraocular lenses commonly used in canine cataract surgery.

The 16S ribosomal ribonucleic acid sequencing was performed on three separate veterinary manufacturers and three different production lots/manufacturers, as well as three other manufacturing lots/manufacturer. Unique brand-specific bacterial DNA profiles were found by rRNA sequencing, which were conserved between IOLs and packaging fluid of all manufacturing lots within each manufacturer's different plant families. Distinct mixtures of bacterial DNA are present and consistent in IOLs and packaging fluid, according to the manufacturer, and Staphylococcus is the most common contributor to the bacterial DNA found. Staphylococcus spp. in Caralens products had a significantly smaller amount of Staphylococcus spp.

Anterior Segment Parameter Changes after Cataract Surgery in Open-Angle and Angle-Closure Eyes: A Prospective Study

Background: To investigate the potential relationship between the anterior ciliary process and the crystalline lens in open-angle eyes and other subtypes of primary angle-closure glaucoma eyes, and to investigate the potential relationship between the ciliary process and crystalline lens. Methods: An observational, prospective study was carried out on 66 patients who underwent cataract surgery, including 22 chronic PACG patients, 22 acute PACG patients, and 22 open-angle cataract patients. A natural anatomic abnormality may be a more significant contributor to the anterior rotation of ciliary functions in PACG patients.

Clinical Outcomes of Cataract Surgery in Patients with Sjögren’s Syndrome

This report compared the biometric accuracy and refractive findings, as well as ocular surface changes after cataract surgery in patients with SjU00f6gren syndrome, non-SS dry eye patients, and healthy controls. The medical records of patients who underwent cataract surgery and fulfilled certain inclusion criteria were reviewed. The S group experienced more severe and persistent OSS exacerbation following cataract surgery; the OSS returned to baseline three months postoperatively. The postoperative UDVA of the S group was less costly than that of the C group from 3 months postoperatively but not different from that of the D group. The refractive outcomes of SS patients were similar to those of other groups, and the postoperative UDVA was not inferior to that of non-SS dry eye patients.

Case report: Suture associated corneal abscess three years after cataract surgery

We present a case of corneal absces three years after uneventful cataract extraction with posterior chamber lens implantation through a limbal incision that resulted in three sutures placed in the clear cornea. An overview of cataract surgery complications are provided by risk factors and bacteriology of suture-related corneal absces, as well as suture related cataract surgery complications.

Comparisons of outcomes and complications of immediate sequential bilateral cataract surgery and unilateral cataract surgery in a tertiary hospital in South Korea

Abstract In a tertiary hospital in South Korea, we investigated the proportions of immediate sequential cataract surgery and unilateral cataract surgery during the coronavirus disease 2019 pandemic and compared visual results between the two groups. At Korea University Guro Hospital by a single surgeon, we reviewed 441 cataract surgeries performed between March 1, 2021, and October 31, 2021. The preoperative corrective distance visual acuity was lower in the unilateral cataract surgery group than the ISBCS group, however there was no significant difference in postoperative CDVA between the two groups compared to the ISBCS group, although there was no significant difference in postoperative CDVA between the two groups.

Late Descemet membrane detachment after uneventful cataract surgery

5 patients with late Descemet membrane detachment after uneventful cataract surgery are pictured here. Observations: Six eyes of five patients were recruited following a retrospective chart review of consecutive patients who suffered DM detachment following uneventful cataract surgery. Patients in both cases reported clear vision immediately after cataract surgery. These patients experienced late DM detachment with reduced vision from days to months, extending their vision from days to months. Conclusion and importance: After uneventful cataract surgery, a detachment of the descemet membrane can occur. To reattach DM, either compressed air or long-lasting intraocular gas can be used.

Effect of Diphenhydramine Gargling on Sore Throat in Patients Undergoing Cataract Surgery with Laryngeal Mask Insertion

Intoduction: Sore throat is a common postoperative complication in patients under general anesthesia. The present review was designed to investigate the effect of diphenhydramine gargling on sore throat in patients undergoing cataract surgery with laryngeal mask insertion. The patients in the intervention group gargled 8 cc of diphenhydramine diluted to 20 c with normal saline 20 minutes before anesthesia induction. Patients in the control group gargled 20 cc of normal saline 20 minutes before anesthesia induction. Initially, 176 candidates of eye surgery using laryngeal mask airway were accepted in the trial, but three patients were refused access to the intervention group due to withdrawal. Conclusion: Gargling 20 milligrams of diphenhydramine suspension 20 minutes before LMA entry in the patients undergoing eye surgery dramatically reduced the post-anesthesia sore throat when compared to the control group.

Femtosecond Laser-Assisted Cataract Surgery: Analysis of Surgical Phases and Comparison with Standard Phacoemulsification in Uncomplicated Cataracts

The aim of this study is to determine the timing of surgical phases and the cumulative dissipated energy of the phacoemulsification phase in femtosecond laser-assisted cataract surgery as well as in standard surgical procedures of phacoemulsification. The mean aspiration time of the residual cortical was 121. 7 s in the PCs and 163. 0 s in FLACS; the mean aspiration time of the phacoemulsification was 36. 6 s in the PCs and 46. 8 s in FLACS; and 66. 0 s in FLACS; the mean aspiration time of the cortical was 66. 6 s in the PCs and 65. 6 s in FLACS were 121. 9 s in FLACS.
