ABSTRACT

Purpose: To assess the rates of postoperative steroid response following dropless cataract surgery using a subconjunctival depot of triamcinolone versus conventional cataract surgery using topical prednisolone. Patients and Methods: We reviewed consecutive cataract surgery cases performed by a single surgeon to determine the likelihood of steroid response, defined as intraocular pressure (IOP) 50% above baseline or IOP > 24 mmHg postoperatively, excluding the first 72 hours. Logistic regression models were performed including baseline characteristics as exposures in the model and steroid response as the outcome. Main outcome measures were the proportion of eyes developing steroid response, risk factors for developing steroid response, and duration of steroid response. Results: Of the 150 dropless and 218 conventional cases, 26 eyes developed steroid response (15 dropless and 11 conventional cases [10% vs 5%, P=0.096]). Risk factors for steroid response included dropless surgery (OR=2.43, 95% CI=1.03-6.02], P=0.046) and prior diagnosis of glaucoma (OR=7.18, 95% CI=2.66-19.22], P<0.001). Baseline IOP, age, sex, race, and axial length did not increase risk for steroid response. Of the eyes with steroid response, more dropless cases had an IOP elevation ≥30 days (9/15 eyes vs 1/11 eyes; P=0.008), including one patient with refractory IOP elevation in the dropless group who required urgent bilateral trabeculectomy for IOP control. Conclusion: Dropless cataract surgery increases the risk of prolonged steroid response postoperatively. Patients with glaucoma have an increased risk of steroid response and may not be good candidates for dropless cataract surgery with subconjunctival triamcinolone.

ABSTRACT

PURPOSE: To assess the prevalence of autoimmune disease (AiD) in patients with primary open-angle glaucoma (POAG) undergoing ophthalmic surgery. DESIGN: Retrospective, cross-sectional study. PARTICIPANTS: Patients with POAG undergoing any ophthalmic surgery and control subjects undergoing cataract surgery at the Massachusetts Eye and Ear from March 2019 to April 2020. METHODS: All available medical records with patient demographics, ocular, and medical conditions were reviewed. Differences in AiD prevalence were assessed and adjusted for covariates using multiple logistic regression. Additionally, a subgroup analysis comparing the POAG patients with and without AiD was performed. MAIN OUTCOME MEASURES: To assess the prevalence of AiD based on the American Autoimmune Related Diseases Association list. RESULTS: A total of 172 patients with POAG and 179 controls were included. The overall prevalence of AiD was 17.4% in the POAG group and 10.1% in the controls (P = 0.044); 6.4% of POAG patients and 3.4% of controls had more than 1 AiD (P = 0.18). The most prevalent AiDs in POAG group were rheumatoid arthritis (4.6%) and psoriasis (4.1%), which were also the most common in controls (2.8% each). In a fully adjusted multiple logistic regression analysis accounting for steroid use, having an AiD was associated with 2.62-fold increased odds of POAG relative to controls (95% confidence interval, 1.27-5.36, P = 0.009); other risk factors for POAG derived from the analysis included age (odds ratio [OR], 1.04, P = 0.006), diabetes mellitus (OR, 2.31, P = 0.008), and non-White ethnicity (OR, 4.75, P < 0.001). In a case-only analysis involving the eye with worse glaucoma, there was no statistical difference in visual field mean deviation or retinal nerve fiber layer (RNFL) thickness in POAG patients with AiD (n = 30) and without AiD (n = 142, P > 0.13, for both). CONCLUSIONS: A higher prevalence of AiD was found in POAG patients compared with control patients undergoing ophthalmic surgery. The presence of AiD was associated with increased risk for POAG after adjusting for covariates. Additional factors may have prevented a difference in RNFL thickness in POAG patients with and without AiD. Autoimmunity should be explored further in the pathogenesis of POAG.

ABSTRACT

OBJECTIVES: To evaluate the impact of a comprehensive cataract surgery curriculum on the incidence of intraoperative complications. DESIGN: We retrospectively compared the total number of cataract surgeries that the residents performed in all of the teaching sites, and the incidences of intraoperative complications (anterior capsule tear, posterior capsule rent, vitreous loss, anterior vitrectomy, zonular dialysis, iris trauma, hemorrhage, dropped lens fragment, corneal wound burn, incorrect intraocular lens) for the surgeries performed at Massachusetts Eye & Ear by residents in the pre-intervention group (residents graduating in 2004 and 2005), before the implementation of a surgical curriculum, and the residents in the post-intervention group (residents graduating in 2014 and 2015). SETTING: Ophthalmology residency program at a major academic institution. PARTICIPANTS: Residents graduating in 2004, 2005, 2014, and 2015. RESULTS: We reviewed 4373 charts. 2086 of those surgeries were performed at Massachusetts Eye & Ear. The incidence of posterior capsule rent/vitreous loss/anterior vitrectomy was lower in the post-intervention group (1.4% versus 7.7%, p < 0.0001). Other complications were also lower in the post-intervention group. CONCLUSIONS: Implementation of a comprehensive cataract surgery curriculum focusing on pre-operative, intra-operative and post-operative interventions, with an emphasis on patient outcomes resulted in a decrease in the rate of intraoperative complications.

ABSTRACT

PURPOSE OF REVIEW: Continuous curvilinear manual capsulorhexis is currently the standard of cataract surgery. In the past several years, new technologies have been developed to improve the consistency and safety of capsulorhexis creation. This article reviews the most recent technologies in capsulotomy formation and their advantages and disadvantages. RECENT FINDINGS: Guidance devices, femtosecond laser capsulotomy and precision pulse capsulotomy improve the centration, circularity and precision of anterior capsulorhexis and capsulotomy. These developments show particular promise for complex cataract surgeries, though clinical data on the refractive outcomes and complication rates of these technologies are currently limited and warrant additional investigation. SUMMARY: New technological advances in capsulorhexis help surgeons achieve a more ideal capsulotomy geometry. Whether this translates into more predictable refractive outcomes and safer surgeries remains an area of future study.

ABSTRACT

PURPOSE: To evaluate the difference between target and actual refraction after phacoemulsification and intraocular lens implantation at an academic teaching institution's Comprehensive Ophthalmology Service. DESIGN: Retrospective study. PARTICIPANTS: We examined 1275 eye surgeries for this study. METHODS: All consecutive cataract surgeries were included if they were performed by an attending or resident surgeon from January through December 2010. Postoperative refractions were compared with preoperative target refractions. Patients were excluded if they did not have a preoperative target refraction documented or if they did not have a recorded postoperative manifest refraction within 90 days. MAIN OUTCOME MEASURES: The main outcome measure was percentage of cases achieving a postoperative spherical equivalent ± 1.0 diopter (D) of target spherical equivalent. RESULTS: We performed 1368 cataract surgeries from January through December of 2010. Of these, 1275 (93%) had sufficient information for analysis. Of the included cases, 94% (1196 of 1275) achieved ± 1.0 D of target refraction by 90 days after cataract surgery. CONCLUSIONS: This paper establishes a new benchmark for a teaching hospital, where 94% of patients achieved within 1.0 D of target refraction after cataract surgery. The refractive outcomes after cataract surgery at this academic teaching institution were higher than average international benchmarks.

ABSTRACT

PURPOSE OF REVIEW: Recent studies have focused on interventions to minimize progression of retinal disease in diabetic patients undergoing cataract surgery. Here, we review the evidence for progression of diabetic retinal disease with cataract surgery and critically analyze the interventions proposed to minimize it. RECENT FINDINGS: Peri-operative intravitreal bevacizumab, sub-Tenon's triamcinolone, and panretinal photocoagulation (PRP) after cataract surgery (instead of before) have been examined as ways to improve cataract surgery results in diabetic patients. The bevacizumab and triamcinolone results are promising, but the inclusion criteria are variable, the sample sizes are small, and the follow-up is short. Postsurgery PRP shows improved cataract surgery results in diabetics with more severe retinopathy up to 1 year after surgery. SUMMARY: Recent studies do not support the generalized conclusion that phacoemulsification surgery causes progression of retinopathy and macular edema in all diabetic patients. In certain populations of diabetic patients undergoing cataract surgery, peri-operative triamcinolone and bevacizumab may blunt the progression of diabetic macular edema and diabetic retinopathy. The optimal timing of PRP in relation to cataract surgery in patients with more severe retinopathy warrants further evaluation.

ABSTRACT

Epithelial downgrowth is a rare, but potentially devastating, complication of intraocular surgery and trauma. It has been suggested that the incidence is declining with modern surgical techniques, but further long-term analysis is needed to determine whether this in fact is true. While clinical observations and experimental studies have helped to elucidate factors involved in the development of this disease, a precise understanding of its pathogenesis is unknown. Given the difficult management and poor prognosis of this disease, further study and heightened clinical awareness are needed to better understand this disease process.
