ছানি অস্ত্রোপচার is one of the most frequently performed surgeries worldwide. However, having a solid understanding of the surgical instruments used in ছানি অস্ত্রোপচার প্রয়োজনীয়
For any operation, including ছানি অস্ত্রোপচার, the appropriate instruments must be available and should be placed in good working order. Using blunt or non-functioning instruments in the surgery can result in poor outcomes and even pose a risk of infection to the patient.
This article provides an overview of the instruments used in ছানি অস্ত্রোপচার, including those specific to Small Incision Cataract Surgery (SICS). It also provides an overview of the safety measures and sterilisation methods employed for cataract surgery instruments.
List of Surgical Instruments Used in Cataract Surgery
ছানি অস্ত্রোপচার requires a variety of specialised surgical instruments for removing the clouded lens and replacing it with an artificial one. Let’s look at all the surgical instruments used in ছানি অস্ত্রোপচার.
Irrigation and Aspiration Instruments
Irrigation and aspiration instruments are necessary in ছানি অস্ত্রোপচার to remove lens fragments, viscoelastic material, and cortex after phacoemulsification. These instruments used in cataract surgery ensure a stable anterior chamber and minimise complications, such as inflammation or posterior capsule opacification.
Common I/A instruments used in ছানি অস্ত্রোপচার include coaxial and bimanual handpieces. These handpieces come with various tip designs, including straight, angled and those with a roughened surface for polishing.
Cutting and Dissecting Instruments
To remove the lens and make thin incisions, the instruments used in cataract surgery are scalpels, knives, scissors and forceps. These tools ensure precision with various blade types, enabling the creation of corneal incisions and the cutting of tissue. Using the right cataract surgery tools helps minimise scars and promotes faster recovery.
Forceps Used in Cataract Surgery
Cataract surgery instruments include various types of forceps for different stages of the procedure. These instruments include capsulorhexis forceps, which are used to create a circular opening in the lens capsule. It also includes forceps for holding the lens and manipulating tissues within the eye.
Other Important Instruments
Surgical instruments for cataract surgery also include:
- Speculum: Keeps the eyelids open during surgery.
- Hydrodissection Cannula: Used to loosen the lens nucleus by injecting fluid.
- Chopper: Assists in dividing the lens during phacoemulsification.
- IOL Injector System: Delivers the intraocular lens into the capsular bag.
Instruments Specific to Small Incision Cataract Surgery (SICS)
Cataract surgical instruments for small incision ছানি অস্ত্রোপচার require tools for delivering large, rigid lenses through a self-sealing scleral tunnel.
AC Maintainer:
Maintains anterior chamber depth by continuous infusion of fluid. Helps prevent chamber collapse during nucleus delivery.
Single-port Cannula:
A single-port cannula is used for precise irrigation to maintain space and assist in cortical clean-up.
Blumenthal Cannula:
The Blumenthal cannula is designed explicitly for SICS to deliver fluid behind the lens, facilitating its expression.
Hydro Cannula:
The Hydro cannula is used to perform hydrodissection, separating the lens nucleus from the cortex and capsule for easier removal.
Wire Vectis:
Wire Vectis is a loop-shaped instrument used to cradle and extract the lens nucleus safely.
Cystitome or Capsulotome:
Cystitome or Capsulotome is used to puncture and tear the anterior capsule, allowing access to the lens.
MVR Blade:
MVR Blade is a sharp, angled blade used for precise side port or tunnel incisions.
Crescent Knife:
Crescent Knife is a blunt-tipped, curved blade used to dissect a scleral tunnel without perforating deeper tissues.
Castravejo’s Calliper:
Castravejo’s Calliper measures incision length and IOL position with precision, aiding surgical planning and symmetry.
Safety Measures and Sterilisation of Cataract Surgery Instruments
Instrument Sterilisation Protocols
- Autoclaving: A commonly used method with steam under pressure.
- EO (Ethylene Oxide) Gas: Used for heat-sensitive items.
- Ultrasonic Cleaners: Used prior to sterilisation to remove debris.
Infection Prevention During Surgery
- Use of single-use consumables wherever possible.
- Maintaining a sterile field with drapes and sterile gloves.
- Proper preoperative patient preparation with povidone-iodine.
Handling and Maintenance of Surgical Tools
- Instruments should be checked for damage before and after use.
- Microsurgical tools require careful manual handling to maintain tip alignment.
- Blades must be disposed of in sharps containers or re-sharpened under the supervision of a trained professional.
Advances in Cataract Surgery Technology
Laser-assisted Cataract Surgery
Femtosecond laser systems aid in automating corneal incisions, capsulotomy, and lens fragmentation. This enables better predictability and reduces dependence on manual techniques.
Innovations in Phacoemulsification
Modern phaco machines offer real-time pressure monitoring, fluidics control, and thermal safety features. These improve nuclear disassembly and reduce complication rates.
Newer Intraocular Lens Technologies
Intraocular lenses now come in various forms, including monofocal, multifocal, toric, and extended depth of focus (EDOF). These forms are tailored to meet the patient’s specific visual needs. Advanced materials help reduce inflammation and improve biocompatibility.
Uses and Importance of Each Instrument in Cataract Surgery
প্রতি ছানি অস্ত্রোপচার instrument has a defined purpose, contributing to:
- Surgical Accuracy: Instruments like callipers and microscissors ensure precise incisions.
- Patient Safety: Tools such as AC maintainers and viscoelastic injectors preserve eye structure.
- Efficient Lens Removal: Phaco probes and vectis loops help safely dislodge and remove the cataract.
- Optimal IOL Placement: Folding forceps and injectors help in seamless lens insertion.
Using the right ছানি অস্ত্রোপচার instrument at each step minimises complications and improves visual outcomes.
