Question 2

Which of the following best describes the assistant's responsibility when handling intraocular lenses (IOLs) during cataract surgery?

Accepted Answer

Following the manufacturer's guidelines for loading and handling to avoid contamination or damage

Answer

IOLs must be handled strictly per manufacturer instructions using appropriate instruments to avoid contamination of the optic or haptics, which could lead to complications.

Question 3

During a trabeculectomy, a mitomycin C-soaked sponge is placed on the sclera. What special handling precaution must the surgical assistant observe?

Accepted Answer

Sponge should be handled with forceps and all MMC-saturated materials must be safely discarded per hazardous waste protocols

Mitomycin C is a cytotoxic chemotherapeutic agent; all MMC-soaked materials must be handled with instruments (not bare hands) and disposed of as hazardous/chemotherapy waste.

Question 4

When assisting with laser photocoagulation for diabetic retinopathy, which contact lens is commonly used to provide a wide-field view of the retina?

Accepted Answer

Panfunduscope or wide-field lens such as the Mainster or Volk lens

Answer

Wide-field contact lenses such as the Mainster or Volk panfunduscope provide a broader view of the peripheral retina needed for panretinal photocoagulation in diabetic retinopathy.

Question 5

A patient undergoing a dacryocystorhinostomy (DCR) will have a silicone tube placed. What is the purpose of this tube?

Accepted Answer

To stent the newly created opening between the lacrimal sac and nasal cavity, keeping it patent during healing
