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.

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.

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.

Purpose. To compare short-term clinical outcomes between two different intraocular lens (IOL) types in the flanged IOL fixation technique. Methods. This study was a retrospective case series and included the patients who underwent flanged IOL fixation between June 2017 and July 2018 at the Hiroshima University Hospital. Two different 3-piece IOLs (NX-70 and PN6A) were used. Recipients of NX-70 and PN6A IOLs were classed into groups 1 (15 eyes) and 2 (25 eyes), respectively. Patient characteristics, surgical results, and postoperative complications were analyzed. We excluded patients with a postoperative follow-up of <1 month. Results. The mean follow-up period was 13.3 ± 11.7 weeks. The postoperative best corrected visual acuity, in logarithm of the minimum angle of resolution (logMAR), was 0.10 ± 0.33 in group 1 and 0.26 ± 0.42 in group 2. The mean operation times for groups 1 and 2 were 11.2 ± 4.54 minutes and 7.00 ± 2.20 minutes, respectively (p=0.0024). Detachment of the IOL haptic from the optic during surgery occurred in four eyes in group 2 (16%), but did not occur in group 1. Iris capture of the optic was observed in 3 of the 13 eyes (23%) without a peripheral iridotomy in group 2. No peripheral iridotomies were performed on group-1 eyes, but iris capture did not occur in that group. Conclusions. There was a trend to fewer intraoperative and postoperative complications when using NX-70 IOLs. On the other hand, PN6A IOLs was easy to maneuver within the anterior chamber, and the operation time was shorter when using PN6A IOLs. Selection of optimal IOLs for flanged IOL fixation necessitates an understanding of their characteristics in terms of intraoperative and postoperative complications.

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.

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.

Introduction: Recently, few studies were reported about the treatment of large, solitary, renal calculi between shockwave lithotripsy (SWL) and percutaneous nephrolithotomy (PNL). We assess the feasibility of SWL for managing solitary, lower calyceal stones over 1 cm by comparing the results of lower pole calculi treatment between patients that underwent SWL or PNL.Methods: We retrospectively reviewed clinical data for patients who had undergone PNL or SWL due to lower calyceal stones over 1 cm. Group 1 consisted of patients who underwent SWL to treat lower pole renal calculi from 2010 to 2011. Group 2 included patients who underwent PNL to manage lower pole renal calculi from 2008 to 2009. We compared patient age, gender, stone size, comorbidities, postoperative complications, additional interventions and anatomical parameters between the two groups.Results: A total of 55 patients were enrolled in this study. The mean ages (±SD) of groups 1 (n = 33) and 2 (n = 22) were 55.1 (±13.0) and 50.0 (±10.6) years (p = 0.133) and mean stone sizes were 1.6 (±0.7) and 1.9 (±0.8) cm (p = 0.135), respectively. There were no significant differences in gender distribution, comorbidities or stone laterality between the two groups. No significant differences in various parameters were observed between patients with stones 1 to 2 cm and ones with stones 2 cm or larger.Conclusions: Our results demonstrated that SWL is a safe, feasible treatment for solitary, lower calyceal stones over 1 cm.

The problem of sternal osteosynthesis after cardiac surgery is relevant because of a relatively high incidence of postoperative complications associated with inadequate sternal consolidation. The use of nitinol clips is one of the reliable and versatile methods of sternal osteosynthesis. Our research included 208 postoperative patients with different cardiac surgical pathologies. All interventions were carried out with cardiopulmonary bypass using median sternotomy. Patients were divided into 2 groups according to sternal fixation methods: group 1 (105 patients) - wire suture osteosynthesis, group 2 (103 patients) - nitinol clips closure. The short-term postoperative results were analyzed by using the major criteria for comparison. Radiographically confirmed varying degrees of sternal defects in the immediate postoperative period were observed in 15.2% of patients in group 1 and 3.8% of patients in group 2. In group 1 significant sternal defects requiring sternal refixation were observed in 4.8% of patients; in group 2 no such cases were identified. The mean blood loss in the drainages for 24 hours after surgery in group 1 was 351 65 ml; in group 2 - 192 43 ml. The total number of resternotomies for bleeding in group 1 was 6.7% of cases, with half of them being the patients with the source from the sternum in the site of wire sutures, while in group 2 4.9% patients underwent resternotomy, with no bleeding from the sites of clip fixation. Thus, the use of nitinol clips after longitudinal median sternotomy is a more reliable method of sternal osteosynthesis (as compared with the classical method), which enables us to minimize the risk of damage to the retrosternal structures, preserve sternal consolidation and reduce blood loss in the drainages in the early postoperative period.

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: 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.

Purpose: To investigate the effect of capsular tension rings (CTRs) on postoperative refractive results in patients with pseudoexfoliation (PSX) syndrome. Materials and Methods: Sixty-nine patients with PSX syndrome who had uncomplicated cataract surgery between March 2016 and February 2019 were reviewed retrospectively. The patients were divided into two groups. The 35 patients in Group 1 received CTRs prior to intraocular lens implantation during cataract surgery, and the 34 patients in Group 2 had cataract surgery without CTRs. Significant zonular weakness, uncontrolled glaucoma, and ocular pathologies causing low visual acuity were excluded. The preoperative and postoperative keratometry and autorefraction measurements, preoperative expected refractive values, and absolute refractive error were recorded. Results: The mean ages of patients were 73.54 ± 9.78 years in Group 1 and 72.23 ± 6.72 years in Group 2 ( p = 0.521). There was no statistically significant difference between Group 1 and Group 2 in terms of expected preoperative refraction values (–0.52 ± 0.12,–0.56 ± 0.08, respectively, p = 0.118). There was a statistically significant difference in postoperative spherical equivalent values between Group 1 and Group 2 (–0.05 ± 0.97 and −0.92 ± 0.57, respectively, p < 0.01). A statistically significant difference was found between the two groups in terms of absolute refractive error (0.46 ± 0.74 in Group 1 and −0.34 ± 0.59 in Group 2 p < 0.01). Conclusion: CTR implantation causes hyperopic shift, which should be taken into consideration when calculating the lens power of intraocular lens in patients with PSX syndrome.
