During a laser trabeculoplasty procedure, what is the primary role of the ophthalmic assistant?
Answer: Position and stabilize the gonioscopy lens on the patient's eye
The ophthalmic assistant's role during laser trabeculoplasty is to assist with patient positioning and stabilize the gonioscopy lens as directed by the physician.
A patient is scheduled for a pneumatic retinopexy. Which positioning instruction is most critical post-procedure?
Answer: Maintain a specific head position to keep the gas bubble over the retinal break
After pneumatic retinopexy, the patient must maintain a specific head position so the intraocular gas bubble tamponades the retinal break.
Which instrument is used to measure the axial length of the eye prior to cataract surgery for IOL power calculation?
Answer: A-scan ultrasonography or optical biometry
A-scan ultrasonography or optical biometry (e.g., IOLMaster) measures axial length, which is essential for calculating intraocular lens power.
When assisting with a chalazion excision, the assistant should be prepared to provide which of the following?
Answer: A chalazion clamp, curet, and local anesthetic
Chalazion excision requires a chalazion clamp to stabilize and evert the lid, a curet to remove the contents, and local anesthetic for patient comfort.
Before assisting with an intravitreal injection, the assistant should verify which critical step?
Answer: That the correct medication, concentration, and dose are confirmed
Confirming the correct medication, concentration, and dose is a mandatory safety check before any intravitreal injection to prevent medication errors.
During phacoemulsification cataract surgery, what does the 'irrigation/aspiration (I/A)' handpiece primarily do?
Answer: Removes residual cortical lens material after nucleus extraction
The I/A handpiece irrigates with balanced salt solution and aspirates residual soft cortical material from the capsular bag after the nucleus has been removed.
A patient undergoing fluorescein angiography suddenly reports nausea and develops hives. What is the most appropriate immediate action?
Answer: Stop the injection, notify the physician immediately, and prepare for anaphylaxis management
Nausea with urticaria (hives) following fluorescein injection indicates a systemic allergic reaction; the procedure must stop immediately and the physician must be alerted for potential anaphylaxis treatment.
