OCPP 101 Chapter 2.3 Refractive Surgeries UPDATED ACTUAL Questions
and CORRECT Answers
1. Refractive is a type of corneal surgery that modifies the shape of the cornea to
surgery correct a refractive error
When considering this, a patient needs to have good ocular structures, good
corneal thickness, suflcient tear film, and an understanding of potential outcomes.
2. Corneal pachym- is the measuring of the thickness of the cornea, and is required prior to
etry (avg 560 mi- any refractive surgery.
crons)
3. ectasia If the cornea is abnormally thin prior to surgery, it may create an abnormal bulging
of the cornea as a side effect called .
4. Pentacam A is an instrument that utilizes a rotating camera to provide a complete
picture from the anterior surface of the cornea to the posterior surface of the lens. It
quickly measures corneal topography, thickness, structural integrity and strength.
Optical surgeons depends on this instrument for critical information.
5. IOP (intraocular Measuring is also required before any refractive surgery Too much
pressure) pressure and a bulge are more possible, too little and the cornea may flatten too
much.
6. 1980s Beginning in the early , refractive surgery became a procedure chosen by
many patients to correct their myopic refractive error.
7. Radial keratoto- was the first refractive surgery. It consists of flattening the cornea by using
my (RK) radial (spoke-like) incisions in the peripheral cornea, done to correct nearsight-
edness (myopia).
This procedure had many side effects, including significant glare, starburst pat-
terns around lights at night, and a risk of wound rupture with blunt trauma to the
eye. This procedure is rarely used today due to the existence of other procedures
that produce better results.
