2. Concept and Positioning of the CataRhex 3

The CataRhex 3 was born from the vision of packing comprehensive capabilities for cataract surgery, MIGS glaucoma procedures, and anterior vitrectomy into an extremely compact platform. Weighing approximately 5 kg, it achieves this without compromising on powerful fluidics or energy control. It is purpose-built for operating rooms with limited space, mobile surgical units, humanitarian missions, and surgical centers requiring top-tier performance coupled with effortless transportability. 

3. Differential Technology — SPEEP®: Independent Control of Flow and Vacuum

The most disruptive element of the CataRhex 3 is the SPEEP® pump. It seamlessly merges the principles of a peristaltic pump for flow control with the dynamic responsiveness of a Venturi system for vacuum. This allows the surgeon to regulate flow and vacuum independently and precisely adjust the "holding force" at the instrument tip—even via the foot pedal—maintaining absolute control during occlusions. In clinical practice, SPEEP delivers an immediate, finely dosed response during delicate maneuvers, such as managing Intraoperative Floppy Iris Syndrome (IFIS) or zonular weakness. 

4. easyPhaco® — Fluidics Philosophy Applied to Phacoemulsification

The easyPhaco® technology relies on a fluidics concept that promotes a "magnet-like" attraction to the tip (easyTip), exceptionally high fragment holding force, and a broad infusion channel that ensures a remarkably stable anterior chamber. The result is highly controlled emulsification where ultrasonic energy is directed primarily at the occluded fragment, drastically reducing efficiency loss and the risk of turbulence. The easyTips are available in optimized sizes for both CO-MICS and MICS techniques (1.6–3.2 mm). 

5. High-Frequency Capsulotomy and Bipolar Diathermy

The CataRhex 3 features a High-Frequency (HF) capsulotomy function that allows surgeons to open the anterior capsule using localized diathermy, eliminating the need for a classic mechanical tear. This is particularly advantageous in cases of hypermature cataracts, ocular trauma, small pupils, or situations where controlling the capsular flap is highly complex. The unit also supports additional HF applications, including specialized manipulations for MIGS.

6. Integrated Anterior Vitrectomy

The platform comes equipped with a built-in compressor for anterior vitrectomy and utilizes a pneumatically driven, continuous-flow guillotine cutter capable of reaching up to ~2,400 cuts/minute, this delivers highly effective vitrectomy with minimal vitreoretinal traction. The integrated compressor entirely eliminates the need for an external air supply—a critical advantage for mobile operating rooms or resource-limited environments.

7. HFDS® — Implant-Free Ab Interno MIGS

Oertli incorporates its proprietary HFDS (High-Frequency Deep Sclerotomy) technology into the CataRhex 3 to enable implant-free ab interno MIGS procedures. Published studies demonstrate a sustained reduction in intraocular pressure (IOP) following combined HFDS and cataract surgery, showcasing highly favorable long-term outcomes (e.g., case series with a 48-month follow-up report significant IOP reduction and a high percentage of qualified successes). The technique utilizes high-frequency energy to create micro-sclerotomies, effectively enhancing aqueous humor outflow. 

8. Ergonomics, User Interface, and Foot Pedal

The CataRhex 3 offers a clean, customizable control interface capable of storing up to 20 user profiles. It features color-coded front connections, an adjustable display, and a robust, linear, water-resistant foot pedal (IPX6 rating). The pedal provides fine linear control, direct access to memory settings, and swift function activation, utilizing wired transmission to guarantee uninterrupted signal stability. All these elements are designed to minimize the learning curve and facilitate highly reproducible surgical workflows. 

9. Intraoperative Safety and Consumable Design

• EasyTips: Angled tips with a wide internal channel designed for continuous holding and steady aspiration.
• I/A Safety Design: Quick Tips featuring an elongated shaft and a strategically positioned opening to significantly reduce inadvertent capsule capture.
• Tubing System Outfitted with an integrated pressure sensor and automatic purging to ensure maximum fluidic safety.
  These specific features drastically reduce the risks of anterior chamber collapse, accidental capsular aspiration, and complications related to IOP fluctuations.

10. Clinical Evidence and Publications

A robust body of literature supports the core concepts integrated into the CataRhex 3. Studies on HFDS consistently demonstrate the efficacy and safety of the technique with long-term follow-up (48 months) and excellent IOP reduction. Furthermore, numerous articles and clinical presentations highlight the practical advantages of SPEEP fluidics and the easyPhaco approach regarding precise fragment control and chamber stability. While many series stem from manufacturer data and collaborating centers, the reviewed bibliography is highly encouraging and strongly supports its adoption by trained professionals. 

11. Ideal Use Cases and Target Users

• Surgeons operating in space-constrained environments (mobile clinics, outreach campaigns, satellite hospitals).
• High-volume phacoemulsification centers that prioritize speed, reproducibility, and uncompromising fluidic control.
• Surgeons regularly performing combined Cataract + MIGS procedures.
• Surgical teams requiring occasional anterior vitrectomy capabilities without the need to invest in standalone external systems. 

12. Competitive Advantages at a Glance

• Ultra-Portability: A highly compact unit ready for operation in seconds.
• Advanced Fluidics (SPEEP): True independent control of flow and vacuum.
• Efficient Emulsification (easyPhaco): Paired with purpose-built easyTips for superior holding power and aspiration.
• All-in-One Integration: Seamless inclusion of MIGS (HFDS) and anterior vitrectomy without relying on external equipment.
• User-Centric Design: Backed by a renowned Swiss manufacturer with a long-standing tradition of engineering excellence.

13. Practical Considerations for Adoption

• Training: While the interface is highly intuitive, optimal utilization requires specific training in SPEEP dynamics and modulation modes (Linear / Pulse / Burst), as well as hands-on practice with easyTips. Oertli provides comprehensive educational resources and instructional videos to support this transition. 
• Consumable Compatibility: It is recommended to verify the local availability of easyTips, HF capsulotomy tips, and pressure-sensor tubing sets.
• Maintenance and Service: As a premium Swiss manufacturer, Oertli maintains a robust regional distribution and support network. Facilities should confirm service turnaround times and spare parts availability with their designated local distributor. 

The CataRhex 3 represents a coherent, modern technical commitment to bringing capabilities that once required much larger machines into any operating room—even mobile ones. Its unique integration of SPEEP® (advanced fluidic control), easyPhaco® (fluidics-driven emulsification), HF capsulotomy, HFDS for MIGS, and built-in anterior vitrectomy makes it an incredibly versatile platform for the modern anterior segment surgeon. Backed by Oertli's Swiss manufacturing heritage and published clinical studies on its key components, the CataRhex 3 stands as a definitive choice for institutions seeking top-tier performance, ultra-portability, and a design engineered for real-world clinical excellence.

1. Materials: Beyond "Hydrophilic" vs. "Hydrophobic"

The choice of material remains a determining factor in biocompatibility, capsular stability, and optical quality.

Hydrophobic (Acrylic)

• Extremely low incidence of late opacification ("glistenings"), especially in glistening-free materials.
• Excellent capsular adhesion → greater rotational stability (crucial in toric lenses).
• Higher rigidity that favors long-term centration.

Hydrophilic (Hydrogel or Hydroacrylic):

• High initial biocompatibility.
• Softer, more malleable platforms → better performance through micro-incisions.
• Slightly higher risk of "calcification-type" opacification in specific models.

Current Trend:

Premium manufacturers are migrating toward advanced hydrophobic acrylics, featuring exceptionally low glistening grades, sharper edges, and enhanced optical scatter control.

2. Optical Architecture: Monofocal, EDOF, Hybrid, and Multifocal

Postoperative visual quality depends as much on the optical design as on the patient profile.

Advanced Monofocals

• Aspheric with aberration correction (between –0.18 and –0.27 µm).
• Typically offer the highest image quality and contrast.
• Ideal for irregular corneas, macular pathologies, or patients prioritizing vision free of photopic phenomena.

EDOF (Extended Depth of Focus) Lenses

• Extend the depth of focus without the classic diffraction of trifocals.
• Reduce halos, enhance intermediate vision, and maintain good tolerance in small pupils.
• Highly useful for active patients seeking partial spectacle independence.

EDOF + Hybrid Multifocality

• Combine refractive/diffractive zones for an extended range.
• Allow functional intermediate and near vision with mitigated side effects.
• Require a strict assessment of the patient's psychological and optical profile.

Diffractive Trifocals

• Best near reading vision at 35–40 cm.
• More intense photopic phenomena depending on the model.
• Indicated for regular corneas in patients with high visual demands.

3. Toric Lenses: Precision and Rotational Stability

Astigmatism correction delivers one of the highest impacts on visual satisfaction.

Critical Factors:

• Capsular stability: Haptic design (C-loop, L-loop, Plateau).
• Haptic angulation (1°–5°): Enhances centration.
• 360° square edge: Reduces cellular migration and increases anchorage.
• Material: Hydrophobic = superior adhesion.

Surgical Recommendations:

• Preoperative assessment with topography + biometry + internal aberrometry..
• Axis marking preferably using digital or intraoperative guidance systems.
• Maintain minimal hydration to prevent rotation during deployment.

4. Cornea-Based Selection: Regularity, HOAs, and Biomechanics

A comprehensive corneal analysis significantly reduces refractive surprises.

Key Considerations:

• Higher-Order Aberrations (HOAs): If >0.4 µm (at 6 mm), avoid multifocals.
• Post-LASIK/PRK corneas: Favor neutral aspheric monofocals or non-diffractive EDOF platforms.
• Extreme K-values: Double-check the optimized A-constant and refractive indices.
• Dystrophies and scars: Strict contraindication for diffractive IOLs.

5. Modern Biometry: Precision and Customization

Refractive prediction relies heavily on the measurement method and surgeon personalization.

Key Points:

• Utilize 4th and 5th generation formulas: Barrett Universal II, Kane, EVO 2.0, Olsen..
• Optimize IOL constants using platforms like ULIB.
• For long eyes: Formulas like Kane minimize residual myopic shifts.
• For short eyes: Consider Olsen and Hoffer Q.
• Dual measurement (IOLMaster + Lenstar/Argos) is recommended in highly complex scenarios.

6. Capsular Stability and Haptic Design

Capsular anchorage is fundamental for the Effective Lens Position (ELP).

Common Haptics:

• Modified C-loop: Stable and flexible; widely used in toric IOLs.
• Modified L-loop: Higher rigidity and capsular friction.
• Plate haptic: Useful in short eyes but carries a higher risk of rotation in toric designs.

Optic Edge Influence:

• Full square edge → Lower PCO rate.
• Textured edge → Reduction of marginal glare.
• Continuous 360° edge → Greater rotational stability.

7. Photopic Phenomena: Halos, Glare, and How to Anticipate Them

Every multifocal or diffractive design generates luminous phenomena.

Minimization Strategies:

• Large photopic pupil.
• Regular cornea free of HOAs.
• Negative dysphotopsias mitigated by polished or textured optic edges.
• Proper patient selection (managing expectations + psycho-visual profile).

Lower-Rate Options:

• Pure EDOF platforms.
• Segmented refractive designs.
• Non-diffractive refractive multifocals (though with less consistency in near vision).

8. Posterior Capsular Opacification (PCO) Management

Although most modern IOLs significantly reduce PCO, it remains a critical parameter.

PCO-Reducing Factors:

• 360° square edge.
• Hydrophobic material.
• Single-piece design.
• Firm capsular contact.
• Thorough cortical clean-up.

PCO and Multifocals:

• Affects visual quality much more noticeably.
• Nd:YAG capsulotomy must be performed with extreme care to avoid refractive shifts, pitting, or decentration.

9. Current Trends in 2025

Lentes monofocales “premium”

Increasing demand for monofocals featuring a smooth extended depth of focus.

Tóricas de última generación

Exceptional rotational stability, consistently well below 4°.

EDOF híbridas

Blending soft diffraction and optimized refractive optics to elevate visual quality.

Plataformas preloaded de 1 paso

Materiales glistening-free

Practically the gold standard across all premium tiers.

10. Conclusion

The proper selection of an intraocular lens relies not solely on the optical design, but on a cohesive synergy of material, haptics, capsular stability, biometry, corneal architecture, and patient expectations.
