Free LASIK Intraoperative Procedures Questions and Answers

Question 1

What is the first critical step after positioning the patient for LASIK surgery?

Accepted Answer

Align the patient’s eye with the laser

Answer

Proper alignment of the patient's eye with the laser system is paramount for accurate treatment delivery. This initial step ensures that the laser beam is centered correctly on the cornea, allowing for precise ablation according to the planned treatment parameters. Misalignment can lead to decentered ablation and suboptimal visual results.

Question 2

Which of the following ensures patient comfort and prevents blinking during LASIK?

Accepted Answer

Eyelid speculum

Answer

An eyelid speculum is a sterile device placed between the eyelids to hold them open throughout the LASIK procedure. This prevents involuntary blinking and ensures a clear, unobstructed surgical field for the surgeon and the laser. It also enhances patient comfort by eliminating the need for the patient to actively keep their eyes open.

Question 3

What happens immediately after creating the corneal flap?

Accepted Answer

Excimer laser reshapes the cornea

Answer

After the corneal flap is created and gently lifted, the underlying stromal tissue is exposed. The excimer laser then precisely ablates (removes) microscopic amounts of this tissue to reshape the cornea according to the patient's specific refractive error. This is the core therapeutic step that corrects vision in LASIK.

Question 4

What is the purpose of eye tracking during laser ablation?

Accepted Answer

Maintains precision of laser treatment

Answer

Eye tracking during laser ablation is essential to compensate for any small, involuntary eye movements the patient might make. The eye tracker continuously monitors the eye's position and directs the laser beam to ensure it always targets the correct area of the cornea. This real-time adjustment maintains the precision of the laser treatment, preventing decentered or irregular ablations.

Question 5

Which fluid is used to irrigate the eye during intraoperative steps?

Accepted Answer

Balanced Salt Solution (BSS)

Answer

Balanced Salt Solution (BSS) is a sterile, isotonic solution specifically formulated to mimic the natural fluid environment of the eye. It is commonly used for irrigation during ophthalmic surgeries like LASIK to keep the corneal surface moist, remove debris, and maintain a clear surgical field. BSS is gentle on ocular tissues, preventing cellular damage.
