Oncocytoma of the upper conjunctival fornix

Oncocytomas are tumors characterized by large, eosinophilic epithelial cells with abundant mitochondria that form ductular or glandular spaces. While these tumors have been described in other organs, those of the ocular adnexa occur infrequently, with the caruncle being the most common site of involvement. Conjunctival oncocytomas are extremely rare and are believed to arise from the ductal elements of the lacrimal gland proper and the accessory lacrimal glands of the conjunctiva. We describe the clinical and histological features of a case of an oncocytoma presenting as an atypically located superior fornix mass in a 78-yearold female, with a review of the literature

Comparison of Corneal Endothelial Cell Loss Between Two Femtosecond Laser Platforms and Standard Phacoemulsification

To analyze and compare the changes in endothelial cell density (ECD) and cumulative dissipated energy (CDE) in patients having cataract surgery with two different femtosecond laser platforms and standard phacoemulsification. This prospective non-randomized comparative study included patients scheduled to undergo cataract extraction using femtosecond laser-assisted cataract surgery (FLACS) (60 eyes) or standard phacoemulsification (60 eyes) between September 2013 and March 2016. The main outcome measures were CDE and percentage of endothelial cell loss. Comparative analysis of CDE and percentage of endothelial cell loss between the two phacoemulsification platforms with respect to conventional and FLACS techniques was performed. The CDE and the 1-month mean percentage of endothelial cell loss was 6.11 ± 3.52 and 9.06% ± 8.77% in the standard phacoemulsification group and 4.65 ± 3.61 and 6.00% ± 8.02% in the FLACS group, respectively (P = .039). In the subgroup analysis based on cataract grading, the CDE was significantly less in the FLACS group compared to the standard phacoemulsification group in both the early and advanced cataract group (P = .002). The percent decrease in endothelial cell loss was statistically lower in the FLACS group when compared to the standard phacoemulsification group in the advanced cataract subgroup (P = .02). FLACS pretreatment resulted in a decrease in CDE and less endothelial cell loss when compared to standard phacoemulsification. The decrease in endothelial cell loss was more prominent in the denser cataract group; thus, FLACS may be most beneficial in those cases. There was no significant difference in results between the two laser platforms. [J Refract Surg. 2017;33(10):708-712.]

Anterior Capsulotomy Outcomes: A Comparison Between Two Femtosecond Laser Cataract Surgery Platforms

To compare capsulotomy outcomes between two femtosecond laser platforms for cataract surgery. This retrospective case series included 205 eyes of 162 consecutive patients (75 male and 87 female) aged 68.32 ± 10.27 years (range: 38 to 92 years) who underwent femtosecond laser-assisted cataract surgery (FLACS) using either the LenSx (Alcon Laboratories, Inc., Fort Worth, TX) or the Catalys (Abbott Medical Optics, Abbott Park, IL) laser platform. Intraoperative assessment of the capsulotomy was performed and graded as one of the following four types: complete treatment pattern (type 1), microadhesions (type 2), incomplete treatment pattern (type 3), and complete pattern but not continuous (type 4). Ninety-seven eyes underwent FLACS using the LenSx platform and 108 eyes using the Catalys platform. Ninety-four capsulotomies in the LenSx group were graded as type 1 (96.91%), and three were graded as type 2 (3.09%); all capsulotomies in the Catalys group were graded as type 1 (100%). There was no statistically significant difference between the LenSx and Catalys groups (P > .05). No intraoperative complications (specifically, no posterior capsular extension or vitreous loss) were noticed in any of the eyes included in the study. The LenSx and Catalys laser platforms demonstrate similar capsulotomy outcomes. The microadhesions that were demonstrated in three cases in the LenSx group did not lead to intraoperative or postoperative complications

Femtosecond Laser-Assisted Cataract Surgery A Report by the American Academy of Ophthalmology

PurposeTo evaluate refractive outcomes, safety, and cost-effectiveness of femtosecond laser-assisted cataract surgery (FLACS) compared with phacoemulsification cataract surgery (PCS).MethodsA PubMed search of FLACS was conducted in August 2020. A total of 727 abstracts were reviewed and 33 were selected for full-text review. Twelve articles met inclusion criteria and were included in this assessment. The panel methodologist assigned a level of evidence rating of I to all 12 studies.ResultsNo significant differences were found in mean uncorrected distance visual acuity, best-corrected distance visual acuity, or the percentage of eyes within ± 0.5 and ± 1 diopter of intended refractive target between FLACS and PCS. Intraoperative and postoperative complication rates were similar between the 2 groups, and most studies showed no difference in endothelial cell loss between FLACS and PCS at various time points between 1 and 6 months. In large randomized controlled studies in the United Kingdom and France, FLACS was less cost-effective than PCS.ConclusionsBoth FLACS and PCS have similar excellent safety and refractive outcomes. At this time, one technique is not superior to the other, but economic analyses performed in some populations have shown that FLACS is less cost-effective
