Cataract Surgery Instrument List
The standard cataract surgery instrument set for modern phacoemulsification includes: phacoemulsification handpiece with ultrasonic tip, irrigation/aspiration (I/A) handpiece, irrigating chopper or second instrument for bimanual technique, capsulorrhexis forceps or cystotome, lens insertion forceps, corneal incision blade (typically 2.2-3.0mm), and various cannulas for viscoelastic injection and intracameral medications 1.
Core Phacoemulsification Instruments
The contemporary approach to cataract surgery centers on small-incision phacoemulsification, which has become the predominant method in most of the world 1. The essential instruments include:
Primary Surgical Instruments
- Phacoemulsification handpiece and tip: The ultrasonic device for nucleus fragmentation and removal. Modern techniques can utilize tips as small as 0.7mm for microphakonit procedures, though standard sizes are larger 2
- Irrigation/aspiration (I/A) handpiece: For cortical cleanup after nucleus removal. Can be coaxial (single instrument) or bimanual (separate irrigation and aspiration instruments) 3
- Phaco sleeves: Cover the phaco tip and I/A instruments
- Irrigating chopper or second instrument: For bimanual phacoemulsification techniques to divide the nucleus 2
Anterior Segment Instruments
- Capsulorrhexis forceps or cystotome: For creating the circular opening in the anterior lens capsule
- Corneal incision blade: Typically creating 2.2-3.0mm clear corneal incisions for modern foldable IOL insertion 1
- Lens insertion forceps: For implanting the foldable intraocular lens
- Various cannulas: For injecting viscoelastic material and intracameral antibiotics 1
Instrument Processing Considerations
Reusable vs. Single-Use Instruments
Both reusable and single-use instruments are acceptable for cataract surgery 4. The choice depends primarily on institutional sterilization costs and volume of cases 5.
- Reusable instruments require immediate-use steam sterilization (IUSS) between cases. When properly processed, they show no bacterial or fungal contamination and maintain safety across millions of procedures 3
- Single-use instruments can be cost-effective in multispecialty hospitals with high sterilization costs, though they carry a significantly higher carbon footprint (5478.2 kg CO2 eq over 5 years vs. 20.6 kg CO2 eq for reusable instruments) 5
Critical caveat: Reusable instruments scored better for ease of use and handling in comparative studies, though complication rates were similar (2.2% vs 3.8%, not statistically significant) 4.
Specialized Equipment
Femtosecond Laser Systems
Femtosecond laser-assisted cataract surgery (FLACS) equipment increases capsulorrhexis circularity and precision of corneal incisions, but is not cost-effective and has not demonstrated superior outcomes compared to standard phacoemulsification 1, 6.
Intraoperative Guidance Systems
Optional advanced technology includes intraoperative aberrometry, optical coherence tomography, and image guidance systems for enhanced refractive outcomes, particularly when implanting specialty IOLs 1.
Medication Delivery Instruments
- Intracameral injection cannulas: For antibiotic administration, which has substantial evidence for reducing postoperative endophthalmitis risk 1
- Subtenon or subconjunctival injection equipment: Alternative routes for postoperative medication delivery 1
Alternative Technique Instruments
For manual small-incision cataract surgery (MSICS) or extracapsular cataract extraction (ECCE), which remain relevant in resource-limited settings or for very dense cataracts 6, additional instruments include larger incision blades and lens loop extractors, though these techniques are less commonly used in developed countries 1.
