Practice questions
- A patient develops a cataract after clinically meaningful ocular radiation exposure. Which cataract morphology is described as the most frequent radiation-associated presentation?
- Which description of the crystalline lens is supported by the reviewed radiation-cataract literature?
- When counseling a patient about radiation-associated cataract risk, which set of exposure-related factors is specifically identified as relevant?
- A clinician uses slit-lamp examination and LOCS III to assess lens opacity. Which limitation of these assessment tools is noted in the review?
- Which modality is described as a promising objective, quantitative alternative for assessment of lens opacities?
- A radiotherapy team wants to improve consistency in lens dose reporting and support lens avoidance when feasible. Which measure best aligns with the review's recommendations?
- A patient with lens-induced uveitis has lens proteins exposed to the anterior chamber. Which mechanism best explains the inflammatory response?
- In a systematic review of reported lens-induced uveitis cases, which finding was present in most included eyes and supports the importance of lens-protein exposure?
- A patient has persistent lens-induced uveitis associated with retained lens material. Which intervention was the predominant definitive treatment in the systematic review?
- A patient with glaucoma and visually significant cataract requests a diffractive multifocal IOL to reduce spectacle dependence. Which recommendation best reflects the cited glaucoma guidance?
- A patient with glaucoma has cataract and clinically important corneal astigmatism. Which IOL option may be considered according to the cited guidance, provided clinical evaluation is careful?
- A patient with glaucoma strongly values reduced spectacle dependence after cataract surgery. Which statement about monofocal-plus and extended-depth-of-focus IOLs is most consistent with the cited guidance?
- When selecting a premium IOL for a patient with glaucoma, which clinical information does the cited guidance emphasize considering?
- A phakic patient with high myopia is being considered for a posterior-chamber phakic IOL. Where is this implant designed to be placed?
- A patient with high myopia asks about posterior-chamber phakic IOL surgery. Which counseling point is most directly supported by the consensus statement?
- Why does the consensus statement identify standardization as important in posterior-chamber phakic IOL surgery?
