Effect of Varying Duration of Ocular Compression on Raised Intraocular Pressure following Fractionated Peribulbar Anaesthesia for Cataract Surgery

Aim: To evaluate the effect of fractionated peribulbar anaesthesia and varying digital ocular compression time on intraocular pressure.Methods: Forty non-glaucomatous patients aged 40 years and older planned for cataract surgery were randomly divided into 2 groups based on the duration for which the globe was compressed digitally following each injection. Patients with a history of glaucoma or those who had had previous ocular surgery were excluded. Group 1 underwent 1 minute of compression and group 2 underwent 2 minutes of compression. Local anaesthetic (2% lidocaine 5 mL, 0.5% bupivacaine 5 mL, and hyaluronidase 25 IU/mL) was injected into the inferotemporal and superomedial quadrants. Intraocular pressure was measured (3 readings with <5% SD) before peribulbar block, after inferotemporal injection, following digital compression, after superomedial injection, following digital compression again, and at 1-minute intervals without compression until the globe attained normotension.Results: The mean (SD) intraocular pressure in group 1 was significantly elevated compared with the baseline mean intraocular pressure of 19.21 mm Hg (SD, 2.82 mm Hg) throughout the procedure (p < 0.0001). In group 2, the mean intraocular pressure was not significantly elevated from the baseline mean intraocular pressure of 19.13 mm Hg (SD, 3.27 mm Hg) following compression after each injection.Conclusions: Intraocular pressure rises significantly following each 5 mL of local anaesthetic injected into the peribulbar space at both the inferotemporal and superomedial sites. Digital ocular compression given for 2 minutes after each injection makes the globe normotensive.

Purpose. The aim of this retrospective cohort study was to evaluate intraocular pressure (IOP) changes during femtosecond laser-assisted cataract surgery (FLACS) using two different patient interface systems. Methods. 116 eyes of 116 patients scheduled for cataract surgery were divided into 2 groups: group 1 (61 eyes) and group 2 (55 eyes) underwent FLACS using Catalys Laser with fluid interface (liquid optics interface, LOI) and LenSx Laser with curved interface and soft contact lens (SoftFit), respectively. IOP was assessed using a portable rebound tonometer (Icare®) preoperatively, after docking, immediately after surgery, at one and seven days postoperatively. Results. In group 1, the mean IOP (±SD) was 14.1 ± 0.4 mmHg before surgery, 33.2 ± 1.1 mmHg after docking, and 21.4 ± 0.9 mmHg immediately after surgery. In group 2, the mean IOP was 13.8 ± 0.4 mmHg before surgery, 24.2 ± 1.4 mmHg after docking, and 20.2 ± 1.2 mmHg immediately after surgery. After the docking procedure, a statistically significant increase in IOP from the baseline was found in both groups (p<0.001). Moreover, no statistically significant difference in IOP measured at 1 and 7 days postoperatively was observed compared with the preoperative values (p>0.05) using both laser platforms. No intraoperative and postoperative complications were observed. Conclusions. FLACS suction phase resulted in a transient increase of IOP in both groups, especially with the LOI system, and it is probably related to the greater pressure of a suction ring and suction generated through the vacuum, independently from the effect of femtosecond laser itself.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

Introduction It is well documented that music plays a role in reducing anxiety levels. Its role in reducing intra-operative anxiety levels in surgical patients while awake is less well known. We report the effects of music on intra-operative patient anxiety in both the elective and trauma plastic surgical setting. Methods Two groups of patients undergoing local anaesthetic surgical procedures were identified: those where music was played in the operating theatre (Group 1) and those where it was not (Group 2). Ninety-six patients were included. Subjectively anxiety was evaluated by the patient with a visual analogue scale (VAS) and objectively by the respiratory rate (RR), both pre and post-operatively. The unpaired t-test was used to evaluate the statistical significance of differences between the groups. Results The mean pre-operative VAS score was similar in both groups (5.7 in Group 1 and 5.8 in Group 2). The mean preoperative RR was 15 breaths per minute in both groups. Post-operatively, the VAS score and RR were both lower in Group 1 (VAS: 3.5 vs 4.9; p<0.01 and RR: 11 vs 13 breaths per minute; p<0.05). Conclusions In the era of the patient centred approach to clinical care, it is crucial to minimise patient anxiety. Music appears to reduce intra-operative anxiety in awake patients in both the elective and trauma plastic surgical setting. Easy listening music and chart classics appear to be suitable genres according to patients. We believe there is a role for a large, multicentre, randomised control study to examine the benefits of music in all local anaesthetic procedures across different specialties.

Objective: To examine the effectiveness and results of primary trabeculectomy with 5-fluorouracil (group 1) or mitomycin-C (group 2) in elderly patients. Materials and Methods: This was a retrospective study including 67 eyes with primary open-angle glaucoma that underwent primary trabeculectomy with group 1 or group 2. Patients who were followed up for less than 1 year or were under 55 years of age were excluded from the study. Surgical success was evaluated according to a decrease in cup/disk ratio and reduction of intraocular pressure without any topical medication. Results: The mean ages of participants were 65.7 years (range 59–88) and 65.9 years (range 59–74) in groups 1 and 2, respectively. The mean preoperative and postoperative intraocular pressure values were 31.3 ± 5.7 mmHg (range 17–46) and 14.8 ± 0.4 mmHg (range 10–21) in group 1 (p < 0.001) and 31.5 ± 7.4 mmHg (range 18–52) and 14.8 ± 2.9 mmHg (range 10–21) in group 2 (p < 0.001). Conclusion: The use of 5-fluorouracil or mitomycin-C during primary trabeculectomy is associated with high postoperative success rates. There were no significant differences between 5-fluorouracil and mitomycin-C in terms of intraocular pressure reduction.

Abstract Purpose: To compare the safety and performance of two ophthalmic viscosurgical devices (OVDs) Bio-Hyalur SV (Sodium Hyaluronate 3.0%) (Biotech Healthcare Group, Luzern, Switzerland) and Protectalon (sodium hyaluronate 2.0%) (VSY Biotechnology, Turkey) in cataract surgery. Methods: One hundred twenty eyes of one hundred twenty patients who underwent phacoemulsification surgery were included in the study. Postoperatively sixty eyes using Bio-Hyalur-SV were classified as Group 1, and sixty eyes using Protectalon as Group 2. Patients aged 45 and over, Grade I, II or III unilateral / double stained cataract, healthy eyes creating cataract inclueded in this study . Endothelial cell morphological parameters including endothelial cell density (ECD), cell number, cell area, coefficient of variation (CV) in cell size, cell hexagonality and central corneal thickness (CCT) were measured preoperatively and at postoperative first week, first and third month visits.Intraocular pressure (IOP) was measured with an applanation tonometer at every visit. Results: . There was a statistically significant decrease in the mean ECD all follow-up times when compared with the preoperative visit (p=0.000). In terms of mean ECD levels there was no significant difference between the two groups within three months postoperatively (p=0.616) In the first week after surgery, there was an significant increase in CCT in Group 1 and Group 2 respectively (p=0.000). The IOP was <23 mmHg in all of the patients on the first day after surgery. There was no significant difference in the incidence of IOP peaks between the two groups in every vizits. In both groups, a significant increase was observed in the mean IOP at first day, first week, and first month after surgery compared to preoperative values (p=0.000). But no significant difference in IOP increase in Group 1 (P=0.092), Group 2 (P=0.013) compared to preoperative values at third month postoperatively (p <0.001 significant with Bonferrotti correction). Conclusion: The two OVD’s used in this study during cataract surgery were safe and effective. Both OVD’s resulted in similar rates of transient IOP increases and corneal endothelial damage also provided good anterior chamber depth and were fairly easy to remove.

Abstract Aim: To evaluate the risk factors, clinical presentation, management and outcome of inadvertent globe perforation during peribulbar anaesthesia.Methods: This retrospective study evaluated the medical records of all the patients treated for globe perforation secondary to peribulbar block preceding ocular surgery from 2012 to 2020. The patients were divided into three groups; Group 1 - clear media with no retinal detachment (RD); group 2 - vitreous hemorrhage (VH) without RD; and group 3 - RD with/without VH.Results: Twenty-five patients (25 eyes) were identified. The incidence of globe perforation was 0.002 %. The mean axial length (AL) was 24.7±2.7mm (Range, 20.9-31.2mm). Eleven eyes (45.8%) had AL≥24mm. The most common presenting features were VH (n=14), ocular hypotony (n=7) and RD (n=7). The treatment included laser photocoagulation for the retinal break(s) (n=7) and vitrectomy (n=17). Retinal breaks were identified in all the patients (total breaks, 37). Other complications included full-thickness macular hole (n=5), subretinal haemorrhage (n=4) and retinal vascular occlusions (n=4). Mean presenting best-corrected visual acuity (BCVA) in group 1,2 and 3 were logMAR 0.79±0.73, 1.82±0.78 and 2.13±0.59 respectively. All the patients, except one who did not undergo surgery due to advanced proliferative vitreoretinopathy, had an attached retina at the time of last follow-up. The mean final BCVA was logMAR 0.59±0.79, 0.48±0.26 and 1.25±0.64 respectively. Conclusion: Early intervention can help manage the eyes with inadvertent perforation successfully. The presence of retinal detachment, as well as macular and vascular complications are risk factors for poor prognosis.

Purpose: To compare the long-term changes in surgically induced astigmatism (SIA) in patients who underwent 23-gauge sutureless vitrectomy and cataract surgery together with patients who underwent cataract surgery only.Methods: We retrospectively reviewed SIA changes for 1 year after surgery in patients who received only cataract surgery using phacoemulsification (group 1) and patients who underwent 23-gauge sutureless vitrectomy and cataract surgery together (group 2). Flat keratometry (K1), steep keratometry (K2), and astigmatism axis were measured with automatic keratometry before and after the surgery. Vector analysis was used to calculate SIA at 1, 3, 6, and 12 months postoperatively. We then examined whether the SIA values at each time point were different between the two groups.Results: A total of 86 eyes were included in this study (group 1, n = 45; group 2, n = 41). The mean SIA values calculated at 1, 3, 6, and 12 months after surgery in group 1 were 0.83 ± 0.37, 0.69 ± 0.39, 0.60 ± 0.33, and 0.59 ± 0.33, respectively. In group 2, the values were 0.82 ± 0.47, 0.69 ± 0.38, 0.62 ± 0.28, and 0.61 ± 0.30, respectively. Over time, SIA decreased in both groups (all p < 0.001). There was no significant difference in the mean SIA between the two groups at each follow-up time point after surgery (p = 0.296, p = 0.728, p = 0.361, and p = 0.356, respectively).Conclusions: When 23-gauge sutureless vitrectomy and cataract surgery were performed together, the astigmatism change caused by surgery did not show a significant difference compared with that of the group who received cataract surgery only. Thus, 23-gauge sutureless vitrectomy may not significantly affect corneal astigmatism.

Background: Cataract is opacity of lens which is treated surgically. Topical corticosteroids are routinely used in the treatment of post-operative inflammation following cataract surgery. This study aims to compare the intraocular pressure changes caused by various topical steroids (prednisolone, dexamethasone and difluprednate) in post cataract patients. To compare compliance and to detect any significant adverse effects.Methods: Patients admitted in ophthalmology department for cataract surgery operated by phacoemulsification were taken as subjects. Total number of patients enrolled in the study were 354. Subjects were separated into 3 groups depending on topical steroids which were prescribed after surgery: group 1 - difluprednate, group 2 -dexamethasone and group 3 - prednisolone. Changes in intraocular pressure (IOP) of patients were measured by ophthalmology department preoperatively and postoperatively after 1st, 2nd, 3rd, 4th week of surgery. These data were collected and analysed. Adverse effects, Compliance of patients and number of bottles of drug used after surgery were also noted.Results: On comparing IOP, there was significant variation (p<0.027) between 3 drugs after one week of drug administration. When group 1 was compared with group 2 or group 3 there was no significant difference Average cost of difluprednate is about 3 times higher than the cost of dexamethasone or prednisolone.Conclusions: All the three topical steroids cause a rise in intraocular pressure in post cataract patients. But in group 1 (difluprednate) there was a rise in IOP up to three weeks after surgery but after 3rd week IOP remained stable. Adverse effects were seen more in group 2 and group 3.

At the time of cataract surgery, one of the challenges a surgeon encounters is intraoperative miosis. This might increase the chances of intraoperative and postoperative complications. Thus, maintainence of adequate pupillary dilatation is necessary during cataract surgery. Aim of the study was to compare the effectiveness of prophylactic administration of topical bromfenac (0.09 % w/V) and topical flurbiprofen (0.03 % w/V) in maintaining mydriasis during the cataract surgery. A total of 100 patients were randomly divided into two groups of 50 each. Group 1 received topical bromfenac (0.09 %) and Group 2 received topical flurbiprofen (0.03 %). The mean percentage loss of mydriasis from the baseline was lesser in bromfenac group compared to flurbiprofen group (p < 0.001). Topical bromfenac was found to be more effective in maintaining mydriasis during the cataract surgery when compared to the topical flurbiprofen.

Purpose: To assess the quantitative changes of macula in diabetic and non-diabetic eyes after uncomplicated cataract surgery. Methods: In this prospective interventional study being performed in a tertiary healthcare hospital, a total of 660 eyes were divided into two groups. Group 1 included 330 eyes from healthy subjects and group 2 included 330 eyes from well-controlled diabetic subjects with no diabetic retinopathy planned for phacoemulsification with foldable IOL implantation by the same surgeon under similar settings. Optical Coherence Tomography (Heidelberg Spectralis SD-OCT) was used to assess preoperative and postoperative central macular thickness (CMT) at weeks 1 and 6. Results: The mean CMT in group 1 preoperatively, at postoperative week 1, and at post-operative week 6 was 257.03 ± 20.904, 262.82 ± 17.010, and 265.15 ± 20.078 μm, respectively. The corresponding values in group 2 were 255.36 ± 17.852, 259.15 ± 16.644, and 266.09 ± 18.844 μm, respectively. There was no significant difference in the mean CMT values between the two groups on any of the three occasions when the CMT was measured (P = 0.374 and P = 0.313 at weeks 1 and 6, respectively). Conclusion: There was no statistically significant difference in CMT between normal subjects and diabetic subjects without diabetic retinopathy preoperatively and in early postoperative period after uncomplicated phacoemulsification surgery.
