Lacrimal Probes are straight metal wires with blunt rounded ends, used to probe the nasolacrimal duct in cases of congenital blockage. They also help identify the lacrimal sac during DCT and DCR surgeries.
Uses
- Probes nasolacrimal duct in cases of congenital blockage.
- Identifies lacrimal sac during DCT and DCR surgeries.
Chalazion Scoop
Description
The Chalazion Scoop is a small cup with sharp margins, attached to a narrow handle. It is used to scoop out the contents of a chalazion during incision and curettage.
Uses
- Scoops out the contents of chalazion during incision and curettage.
Sinskey Hook (IOL Dialer)
Description
The Sinskey Hook is a fine, yet sturdy instrument used for positioning non-foldable IOLs in the capsular bag or ciliary sulcus during cataract surgery. It can also manipulate the nucleus in phacoemulsification surgeries.
Uses
- Positions non-foldable IOLs in the capsular bag or ciliary sulcus.
- Manipulates the nucleus during phacoemulsification.
Kelman-McPherson Forceps
Description
These fine forceps are primarily used to hold the superior haptic of IOL during placement. They can also tear the anterior capsular flap during ECCE and assist in suture tying.
Uses
- Holds IOL haptic during placement.
- Tears anterior capsular flap in ECCE.
- Can be used for suture tying.
Iris Repositor
Description
The Iris Repositor is a delicate, flat, malleable instrument with a blunt tip used to reposition the iris in the anterior chamber during intraocular surgery.
Uses
- Repositions iris in the anterior chamber.
- Breaks synechiae during surgery.
Two-Way Irrigation and Aspiration Cannula
Description
This cannula is used in cataract surgery for both irrigation and aspiration of the lens matter. It can also aspirate hyphaema.
Uses
- Used for irrigation and aspiration during cataract surgery.
- Aspirates hyphaema.
Chalazion Clamp
Description
The Chalazion Clamp is used to fix the chalazion and achieve hemostasis during incision and curettage. It has a disc on one limb and a small circular ring on the other for proper fixation.
Uses
- Fixes chalazion and achieves hemostasis during incision and curettage.

Description
These forceps are used to fix the eyeball during surgeries and during forced-duction tests to stabilize the eye.
Uses
- Fixes the eyeball during surgery and holds the eye during tests.
Superior Rectus Holding Forceps
Description
These forceps are used to hold the superior rectus muscle during bridle suture placement and stabilize the eyeball during surgery.
Uses
- Holds the superior rectus muscle during bridle suture placement.
- Stabilizes the eyeball during surgery.
15° Side Port Entry Blade
Description
This fine straight knife is used to make a small, valvular corneal incision, commonly referred to as a side port incision, during phacoemulsification and other intraocular surgeries.
Uses
- Creates small valvular corneal incisions in phacoemulsification and other intraocular surgeries.
