RESUMEN

PURPOSE: To compare the intraoperative complication rates in cataract surgery performed by resident trainees and staff ophthalmologists. SETTING: Kensington Eye Institute, University of Toronto, Toronto, Canada. DESIGN: Prospective case series. METHODS: This study included 8738 consecutive cases of primary phacoemulsification cataract surgery performed by staff surgeons and resident trainees from January to December 2016. There were no exclusion criteria. Data collected included the level of resident training, case complexity, degree of resident involvement, and intraoperative complications. Primary outcome measures included intraoperative complication rates and level of complexity of cataract surgeries performed by resident trainees and staff surgeons. RESULTS: Resident trainees were involved in 44% of surgeries. Of those, 82% were completed in their entirety by a resident and 18% were performed by both the staff surgeon and resident. Staff surgeons performed 56% of all surgeries without resident involvement. Sixty-seven percent of surgeries were simple and 33% were complex, with small pupil or intraoperative floppy-iris syndrome being the most common reason for complex cases. For simple cases, there was no difference in the overall complication rates (1.7% and 2.0%; P = .52), posterior capsule rupture rates (0.9% and 0.8%; P = .76), or vitreous loss rates (0.4% and 0.2%; P = .08) between staff and residents, respectively. CONCLUSION: There were no differences in complication rates between the two groups.

RESUMEN

Nonsteroidal antiinflammatory drugs (NSAIDs) have become an important adjunctive tool for surgeons performing routine and complicated cataract surgery. These medications have been found to reduce pain, prevent intraoperative miosis, modulate postoperative inflammation, and reduce the incidence of cystoid macular edema (CME). Whether used alone, synergistically with steroids, or for specific high-risk eyes prone to the development of CME, the effectiveness of these medications is compelling. This review describes the potential preoperative, intraoperative, and postoperative uses of NSAIDs, including the potency, indications and treatment paradigms and adverse effects and contraindications. A thorough understanding of these issues will help surgeons maximize the therapeutic benefits of these agents and improve surgical outcomes.

RESUMEN

UNLABELLED: The surgical management of cataract in the small eye presents the ophthalmic surgeon with numerous challenges. An understanding of the anatomic classification in addition to a thorough preoperative assessment will help individualize each case and enable the surgeon to better prepare for the obstacles that might be encountered during surgery. Small eyes are especially challenging in terms of intraocular lens (IOL) calculations and possible current limitations of available IOL powers, which could necessitate alternative means of achieving emmetropia. Surgical strategies for minimizing complications and maximizing good outcomes can be developed from knowledge of the anatomic differences between various small-eye conditions and the pathologies that may be associated with each. A thorough understanding of the challenges inherent in these cases and the management of intraoperative and postoperative complications will ensure that surgeons approaching the correction of these eyes will achieve the best possible surgical results.

RESUMEN

OBJECTIVE: To conduct a needs assessment survey of Canadian ophthalmologists to determine whether there is a requirement for translational aids in ophthalmology, and if so, the content, format, and languages to include. DESIGN: Anonymous voluntary online needs assessment questionnaire. PARTICIPANTS: A total of 139 ophthalmologists completed the online needs assessment questionnaire. METHODS: An anonymous voluntary online survey in English and French was distributed to 700 active members (practicing Canadian ophthalmologists) of the Canadian Ophthalmological Society. Data were collected regarding the potential utility of translational aids, as well as the contents and languages that should be included if such aids were to be created. Level of support for translational aids, as well as the contents and languages of potential translational aids, was assessed. RESULTS: The survey response rate was 19.9% (139/700). The majority of the respondents (130/139, 93.5%) have encountered difficulty in communicating with patients because of language barrier, and 88.5% (123/139) would benefit from having a list of ophthalmologic terms translated into several of Canada's most popular languages. The top 10 languages that the respondents indicated would be most beneficial are (in descending order): Chinese, Hindi, Spanish, Punjabi, Italian, Portuguese, Arabic, Greek, Cree, and Vietnamese. The survey responses provided a comprehensive list of the most useful ophthalmologic symptoms, instructions to patients, and diagnoses to be translated. Most respondents (120/139, 86.3%) believed that having basic information pamphlets on specific ocular conditions translated into several languages would benefit their practice; the top 3 conditions were cataract, glaucoma, and age-related macular degeneration. Producing the translational aids in both paper and electronic format was found to be the most favoured (89/139, 64.0%). CONCLUSIONS: Canadian ophthalmologists believe they would benefit from translational aids. The results of this survey provide a framework for the creation of such aids.

RESUMEN

A 2014 online survey of the American Society of Cataract and Refractive Surgery members indicated increasing use of intracameral antibiotic injection prophylaxis compared with a comparable survey from 2007. Forty-seven percent of respondents already used or planned to adopt this measure. One half of all surgeons not using intracameral prophylaxis expressed concern about the risks of noncommercially prepared antibiotic preparations. Overall, the large majority (75%) said they believe it is important to have a commercially available antibiotic approved for intracameral injection. Assuming reasonable cost, the survey indicates that commercial availability of Aprokam (cefuroxime) would increase the overall percentage of surgeons using intracameral antibiotic injection prophylaxis to nearly 84%. Although the majority used topical perioperative antibiotic prophylaxis, and gatifloxacin and moxifloxacin were still the most popular agents, there was a trend toward declining use of fourth-generation fluoroquinolones (60%, down from 81% in 2007) and greater use of topical ofloxacin and ciprofloxacin (21%, up from 9% in 2007).

RESUMEN

PURPOSE: To examine the subjective patient experience after cataract surgery. SETTING: Single multisurgeon cataract facility. DESIGN: Prospective intraindividual observational study. METHODS: Patients completed a questionnaire immediately after cataract extraction performed in their second eye. All patients had second-eye surgery within 6 months of first-eye surgery. Cases longer than 30 minutes were excluded. RESULTS: Of the 292 patients who completed the questionnaire, 12 were excluded based on surgical time. The response rate varied per question. The surgery was rated as taking longer or being more painful in the second eye by 127 patients (45.4%) and in the first eye by 38 patients (13.5%) (P < .05); 115 patients (41.1%) reported no difference. Patients (47.83%) who rated the second eye as the generally more negative experience thought their vision would be better and 3.48% worse (P < .05); 48.70% thought it would be the same. No difference was noted in length of surgery (P = .3) or sedation used (P = .96). CONCLUSIONS: Of 125 patients who rated second-eye surgery as the generally more unpleasant procedure, 90 (72.0%) were similarly or more relaxed during the second procedure. Second-eye cataract surgery was perceived as being a longer and/or more painful procedure by a significant number of patients (45.4%), and only 3.48% thought that vision in the second eye would be worse. These results can help surgeons when counseling patients regarding expectations for second surgery.

RESUMEN

UNLABELLED: Improvements in phacoemulsification technology and instrumentation and intraocular lens materials and design have enabled cataract surgery to be performed through incisions smaller than 2.0 mm in external width. This evolution has occurred over time, with new challenges arising at each step of the decrease in incision size. This article reviews the current trend of using increasingly smaller incisions to perform phacoemulsification. Specifically, each facet of phacoemulsification is briefly reviewed from a historical context and then evaluated predominantly from a current perspective to better understand the development of the microincision in cataract surgery. The goal is to help the operating surgeon recognize the potential benefits as well as the potential weaknesses of the smaller incision.

RESUMEN

OBJECTIVE: To identify sex differences in lifestyle and practice patterns of Canadian ophthalmologists. DESIGN: Web-based national survey. PARTICIPANTS: Members of the Canadian Ophthalmological Society. METHODS: A 48-item questionnaire was sent electronically. Analysis of results was completed using χ(2) and Fisher's exact tests where appropriate. RESULTS: Of 385 respondents (30%), 102 were female and 283 male. Several statistically significant differences exist in lifestyle and practice patterns. Fifty-one percent of females operate less than 2 days per month as compared with 36% of males (p = 0.01) despite similar clinical hours. No statistically significant differences were found in other practice pattern parameters including laser refractive surgery, hospital affiliation, university appointment/rank, and number of peer-review publications. Ninety percent of males and 81% of females report having ≥1 children, but males report greater number of children (p < 0.001). Females are commonly the primary caregiver, whereas males report their partner as primary caregiver (p < 0.001). Fifty-two percent of females are unhappy with the amount of parental leave (p < 0.001). Fifty-one percent of females believe that childbearing slowed or markedly slowed career progress, as compared with 15% of males (p < 0.001). Both female (83%) and male (87%) ophthalmologists report high career satisfaction (p = 0.43). CONCLUSIONS: Differences in practice patterns between males and females in our analysis surround surgical time, with no difference seen in other practice patterns or academic achievements. Differences in family patterns surround household and childrearing duties. Despite differences, both males and females report high satisfaction across several professional and personal parameters. Compared with previous studies, this suggests a change in practice patterns over time.

RESUMEN

The surgical management of ectopia lentis presents the ophthalmic surgeon with numerous challenges and options. From the clinical evaluation to the surgical approach, ectopia lentis patients require additional methodologies, techniques, and devices to ensure the best possible outcome. The continued refinement of surgical techniques and adjunctive prosthetic devices has led to incremental improvements in the ability to achieve successful in-the-bag placement and centration of intraocular lenses while reducing complications. A thorough understanding of the challenges inherent in ectopia lentis cases and the management of intraoperative complications will ensure that surgeons approaching the correction of these eyes will achieve the best possible surgical results.
