The procedure that corrects the inversion of the lower eyelid is:
a) chalazion removal
b) ptosis correction
c) entropion repair
d) ectropion repair - Correct Answer -c) Entropion repair.
It is corrected to prevent corneal irritation and scarring from constant
rubbing by the eyelashes.
A surgical schedule would describe the procedure to correct drooping of
the upper eyelid as:
a) ptosis correction
b) chalazion removal
c) scleral buckling
d) trabeculectomy - Correct Answer -a) Ptosis correction.
It might be repaired for cosmetic or visual reasons.

,The procedure for removal of a fleshy encroachment onto the cornea is
a/an:
a) ectropion repair
b) pterygium excision
c) hordeolum excision
d) scleral buckling - Correct Answer -b) Pterygium excision.
A pterygium is a fleshy growth that extends from the conjunctiva onto
the cornea. It is removed because it can grow across the front of the
cornea, impeding sight.
In addition to the sterile tray for a lacrimal evaluation, the setup for a
procedure to open a blocked tear duct would include:
a) blunt needle
b) set of probes
c) cautery unit
d) electrolysis unit - Correct Answer -b) Set of probes.
A probe is the wire-like instrument that is passed through the punctum
and canaliculus, then pushed through the blockage.
Laser refractive surgery seeks to correct a refractive error by:
a) altering the shape of the cornea
b) altering the shape of the retina
c) improving the tear film
pg. 2
,d) inserting a retinal implant - Correct Answer -a) Altering the shape of
the cornea.
The cornea accounts for most of the refractive power of the eye. It is
also accessible, as opposed to the other parts of ocular media, except for
the tear film. Changing the cornea's shape (flattening or steepening)
alters the refractive error.
In which of the following refractive procedures is a corneal flap created
and laser used to sculpt the underlying tissue?
a) intrastromal rings
b) radial keratotomy (RK)
c) laser-assisted in-situ keratomileusis (LASIK)
d) photorefractive keratectomy (PRK) - Correct Answer -c)
In LASIK surgery, a microkeratome (a keratome is a surgical knife/blade
used to incise the cornea; a microkeratome is small and capable of
making very precise incisions) is used to cut a thin flap in the top most
corneal layers. The excimer laser is then used to sculpt the underlying
tissue to correct the refractive error. The flap is then put back into place,
over the ablated area.
Laser refractive surgery is performed with which type of laser?
a) argon
b) excimer
c) YAG
d) krypton - Correct Answer -b) Excimer.
pg. 3
, The name excimer is derived from "excited dimer." This laser uses
ultraviolet radiation that breaks or photoevaporates chemical bonds
between tissues and is ideally suited for work on the cornea.
All of the following are forms of laser refractive surgery except:
a) RK
b) PRK
c) LASIK
d) laser-assisted subepithelial keratomileusis (LASEK) - Correct Answer
-a)
In RK, the surgeon uses a diamond blade to alter the cornea's shape.
Which of the following allows the surgeon to customize laser refractive
surgery during the procedure?
a) wavefront LASIK
b) aberration-free LASIK
c) LASIK IOLMaster (Carl Zeiss, Jena, Germany) software
d) LASIK corneal keratometry - Correct Answer -a)
Wavefront technology creates a rough map of the patient's eye, allowing
very precise control and treatment during the refractive procedure. The
idea is to reduce aberrations, thus reducing side effects such as glare,
haloes, and blur. The other answers are bogus.
The sterile field is an area that is considered to be:
