– APPLICATIONS AND MECHANICS
Dr Sanjoy Sanyal
Professor and Surgeon
Who Will Need This?
 Ophthalmic Residents inTraining
 Ophthalmic SurgeryTechnicians
 Ophthalmic OperatingTheater Assistants
 Ophthalmic Surgery Nurses
 Medical Students with interest in Ophthalmology
Foreword
 No specific order has been followed while describing the
instruments
 Cataract being very common, most instruments are related to
Cataract surgery
 Instruments were obtained from an Ophthalmologist’s clinic
and pictures were taken with the author’s Low-Res camera
 This is not a comprehensive list, not by a long shot! More such
presentations will follow in due course
Artery (Mosquito/Halsted) Forceps
 Basic instrument
for any surgery
 Numerous sizes
exist
 Straight / Curved
Jaws
 Small (4") Straight /
Curved are a.k.a.
Mosquito /
Halsted's Forceps
(afterWilliam
Stewart Halsted)
 Straight is for
holding Stay-
sutures orTissues
 Curved is for catching / crushing small
bleeders; a.k.a. 'Hemostat Forceps'
Simcoe Irrigation-Aspiration Cannula
 Two Cannulae merged together, in Ophthalmic Surgery
 One Hub is to introduce fluid in Anterior Chamber (AC)
 Other Hub is to extract Lens matter, Blood etc from AC
Universal Eye Speculum
 Separates Eyelids during Ophthalmic Procedures
 Universal: Can be used on either Eye
 Unguarded: Eyelashes can project into operating field
 Adjustable: Screw-Handle controls separation of Eyelids
 Screw-Handle is always onTemporal Side of Orbit
Barraquer Wire Speculum – Adult
 Separates
Eyelids
 Used on either
eye
 Unguarded:
Eyelashes can
project into
operating field
 Non-
Adjustable:
Fixed 22-25
mm
separation of
Eyelids
 Springy light-wire Instrument
Adult-size is 14 mm (length of Eyelids)
Strabismus / Squint / Muscle Hook
 To lift up
muscle during
Strabismus
(Squint) surgery
 Double-curved
end for hooking
up Muscle
 Sideways
flattened tip for
ease of
insertion under
Muscle near its
insertion
 Distinguish from Lens Expressor
(blue inset picture), used to force out
Lens in Cataract Extraction
Superior Rectus-Holding Forceps
 Special double-curve to go inside Orbit and over Eyeball
 Toothed tips for firmly grasping Superior Rectus Muscle
Suture-Tying Forceps (Straight)
 Fine-limbed
Non-
toothed
forceps to
hold fine
sutures (8-0)
 Inner surface
of Tip is
faintly
ridged, flat
and slightly
roughened
to hold the
fine suture
 Straight Suture-Tying Forceps are held in
Left Hand, for holding one end of the Suture
Suture-Tying Forceps (Curved)
 Curved Suture-Tying Forceps are held in Right Hand, for
holding other end of the Suture and tying the knot
de' Wecker's Iris Scissors
 Small,
Slender
spring-
open
Scissors
 Slightly
larger
than
Vanna‘s
Scissors
 For Iridectomy and other delicate Intraocular
Procedures
Dastoor Pupil and Iris Repositor
 Two-
limbed
instrument
 Pupil
Repositor:
Forked at
the tip;To
reposition
Pupillary
Margin
 Iris Repositor: Flattened and rounded at the tip;To move or
reposition the Iris during Intraocular Maneuvers
Utrata Capsulorhexis Forceps
 Removes
central
portion of
Anterior
Capsule of
Lens in
continuous
curvilinear
fashion (
Continuous
Curvilinear
Capsulo-
rhexis
(CCC))
 Fine, Non-toothed, Sharp-tipped, slightly
forward-hooked Forceps
 Forward hook mimics a Cystitome
Kelman-McPherson IOL Forceps
 Fine sharp-
tipped non-
toothed
forceps
 AngulatedTip
 For holding
and inserting
Intraocular
Lens (IOL) in
Capsular bag
Phaco Chopper / Sinskey Hook IOL
Dialer
 Chopper
Tip:Very
sharp
curve,
used
along
with
Phaco
Probe for
cutting
Cataract
Lens
 Sinskey Hook DialerTip: Curved round hook;
Fits in IOL Dialer Holes or at IOL Haptic-Optic
Junction, for Positioning the IOL in Capsular bag
Thank you for
