RESUMEN

Purpose: To compare the outcomes of active-fluidics based torsional phacoemulsification in diabetics and nondiabetics using a balanced tip. Methods: Two hundred and forty-eight patients undergoing senile cataract surgery using torsional phacoemulsification on an active-fluidics-based platform from December 2016 to August 2017 were included in this prospective, nonrandomized, interventional cohort study; of the 248 patients, 54 were controlled diabetics and 194 were nondiabetics. Intraoperative parameters such as cumulative dissipated energy (CDE), total ultrasound time, torsion usage time, torsion amplitude, aspiration time, and fluid usage were documented and compared. Endothelial cell loss (ECL) and central corneal thickness (CCT) were evaluated at 1 month postoperatively. Results: Diabetics and nondiabetics did not differ in CDE, total ultrasound time, torsion amplitude, aspiration time, fluid usage, endothelial cell count, and CCT. ECL on Day 1 (10.2 ± 8.0%) and Day 30 (11.05 ± 8.3%) were significantly higher in diabetics (P = 0.025 and P = 0.045, respectively). There was an increase in CCT on Day 1 (P = 0.018), which settled by Day 30. Grade 4 cataracts in diabetics had significantly higher CCT at Day 1 (P = 0.032) and Day 30 (P = 0.007). In the diabetic subgroup, Grades 3 and 4 cataracts required lower CDE (P < 0.001) and Grade 4 cataracts showed higher ECL than others till 1 month of follow-up (P < 0.05). Conclusion: Intraoperative and postoperative parameters after torsional phacoemulsification are comparable in diabetics and nondiabetics. Endothelial changes and pachymetry may be related to the grade of cataract in diabetics.

RESUMEN

In this new technique of cataract surgery in patients with iris-fixated phakic intraocular lens with cataract, phakic IOL is explanted at the end of surgery. Phakic IOL remains stable and securely enclaved to the iris during phacoemulsification which is performed through a small 2.2 mm incision. Endothelial protection is provided by viscodispersive OVD above the phakic IOL and space for surgery is created by high molecular weight viscocohesive OVD beneath the phakic IOL. This technique provides significant advantages from the previously described techniques in terms of chamber stability, endothelial protection, iris trauma and surgical ease.

RESUMEN

A 10 year old girl present with both eyes central cataract with posterior lenticonus. Intraoperative, she was noted to have both eyes persistent fetal vasculature (PFV). To the best of our knowledge, association of bilateral posterior lenticonus and PFV has not been reported before. This supports the hypothesis that PFV has a role in pathogenesis of posterior lenticonus.

RESUMEN

Purpose: To review the nature of firecracker-related ocular injuries at a tertiary eye hospital in northern India following the firecracker ban and also to review the level of awareness among the victims. Methods: A cross-sectional observational study involving the patients presenting with firecracker-related ocular injuries from October 18 to 27, 2017 were assessed for demographic distribution, detailed ocular evaluation, and a questionnaire related to the awareness about the injuries. Results: A total of 68 patients were observed. Fifty patients (74.5%) were males. This year, a majority of patients were from outside Delhi. Uttar Pradesh constituted the most 38.23% of the patients followed by Haryana 30.88%, Delhi 23.5%, and Bihar 7.35%. Visual acuity varied from 6/6 to no perception of light. Open globe injury was observed in 56 patients (82.35%) who commonly had zone I injury. A significant number of patients (88.23%) were aware of firecracker-related injuries, and a large number of such injuries (58.8%) occurred in those who were not actively involved in the ignition of firecrackers but were in the vicinity. Conclusion: This year, following a ban, the number of firecracker-related ocular injuries reported from areas outside Delhi outnumbered as compared to within Delhi. However, firecracker-related ocular injuries are still a major cause of significant visual loss, especially involving the bystanders. Thus, firecracker-related celebrations should be monitored with a stringent protocol.

RESUMEN

BACKGROUND: In Pakistan, there is a lack of information about the work environment of residency programs. This lack is a major impediment in their improvement. One of the approaches for improvement in these programs can be directed through the residents' own perception of their working conditions. Therefore, we collected data which would reflect working conditions of residents. AIM: To assess the perceived status of "work environment" in different specialities. MATERIALS AND METHODS: A cross-sectional survey was conducted in four teaching hospitals of Karachi from July 1999 to January 2000. Residents from selected programs were grouped into four broad groups: specialist, medical, surgical and multidisciplinary. Responses of residents were obtained on a Likert scale of 0 to 4. Indices were formed for two components of work environment: academic and mistreatment. STATISTICAL ANALYSIS: Differences between residents' groups were assessed through analysis of variance (ANOVA) at 5% significance. RESULTS: A total of 341 registered residents responded (response rate: 75%). Surgical residents were working more than 80 h/week and this was more than the other three groups. Medical residents were spending the highest actual time on research and teaching activities (10% and 14%, respectively). Academic index score was highest for surgical group (15.81, SD = 4.69) and lowest for multidisciplinary group (11.82, SD = 4.80). Medical group had the highest perceived mistreatment index score (5.56, SD = 4.57). CONCLUSIONS: In a study of work environment of residency programs, differential impact was found for the four groups on work environment perceptions. Most of the residents recognized undergraduate teaching, grand rounds, patient rounds and seminars or workshops as contributing to their academic learning. Reporting of sexual harassment was low, indicating either underreporting or cultural dynamics of our setting.

RESUMEN

CONTEXT: The delineation between selection of surgery and non-surgery residency programmes could provide a pragmatic view of the influences on medical graduates' careers. This would also help coordinators and educators of residency programmes in surgery to further understand the dynamics of specialty selection. AIMS: To identify the different factors that influence the graduates to select surgical specialties in Pakistan. SETTINGS AND DESIGNS: A cross-sectional survey was conducted in 4 teaching hospitals of Karachi between July 1999 and January 2001. SUBJECTS AND METHODS: A total of 455 residents in 1-5 years of residency programmes were contacted. Three hundred and forty-one residents consented to the interview. Residents who were registered both with the College of Physicians and Surgeons of Pakistan (CPSP) and the Post Graduate Medical Education (PGME) office of the selected hospitals were included in this study. STATISTICAL METHOD USED: Logistic regression analysis. RESULTS: Final multivariate analysis identified 4 factors that remained significantly associated with the selection of surgical specialty: deriving gratification from direct patient care (adjusted odds ratio [aOR] = 5.79; 95% confidence interval [CI]: 1.24, 26.99), procedure-based medical practice (aOR = 2.85; 95% CI: 1.23, 6.61), nature of clinical problems (aOR = 3.39; 95% CI: 1.47, 7.84), and lack of consideration of stress during professional work (aOR = 2.27, 95%CI: 1.25, 4.13). CONCLUSIONS: Direct patient care is perceived to be an integral part of surgery residency and immediate patient outcome is a positive influence in selecting surgical specialty. The inclination towards surgery appeared to be determined by the type of procedures and technical skills involved in its practice. The nature of clinical problems is an important determinant of the choice of specialty. Stress was not perceived to be an important influencing factor for those who decided to select surgical specialties.
