Recently, the first unit in ChinaJohnson & Johnson"White Force Seventh Generation Catalys 7.0" Navigation Femtosecond LaserPhacoemulsification SystemFormalSettled in Fudan University AffiliatedThe Pudong Campus of the Eye, Ear, Nose, and Throat Hospital marks the official entry of refractive cataract surgery in China into "Intelligent Bladeless, Precise Navigation" A New Era。

Catalys 7.0 It is an integrated scanning laser system used forCataract Surgery Lens Extraction, including anterior capsulotomy, lens fragmentation, and the creation of single-plane and multi-plane arcuate cuts or incisions in the cornea.

The system is characterized by high accuracy and high precision., which can be personalized based on the patient's individual scan data.Improving the Centration of Refractive Intraocular Lens After Implantation, avoiding intraoperative damage to the cornea and iris, as well as postoperative complications such as astigmatism and glare. In addition, Catalys 7.0 also optimizes the process of femtosecond laser-assisted cataract and presbyopia surgery.Shortened the operation time, making the entire surgery seamlessly completed.

# Catalys 7.0, the Seventh Generation of Bausch + Lomb

Femtosecond laser, as an ultra-short pulse laser, has the advantages of high instantaneous power, precise focusing, strong penetration, and high precision, opening up a completely new treatment pathway in the field of cataract treatment. Compared with traditional phacoemulsification surgery,The entire femtosecond laser process is digitally controlled by a computer system.Convert several key steps in traditional cataract surgery, such as clear corneal incision, capsulotomy, and nucleus segmentation, to be automatically performed by femtosecond laser.。

The Next-Generation Femtosecond Laser Cataract Surgery Platform Launched by Johnson & Johnson Vision"White Force 7th Generation Catalys 7.0"With its unique1-Second Capsulotomy, Full-Range Nucleus Fragmentationand other features, leading femtosecond cataract surgery into the digital and intelligent era.

Product Features

Gentle and Knife-Free：The entire surgical procedure uses laser instead of traditional instruments, achieving one-step operations such as incision, capsulotomy, and nucleus division.No pain during the surgery, zero bleeding during the procedure., reducing the patients' suffering and postoperative recovery time.

Personalized Astigmatism Correction：BuildIris PositioningNavigation and high-definition scanning dual systems,Supports Two Personalized Astigmatism Correction Modes，Able to provide personalized astigmatism correction solutions based on the specific conditions of patients.。

ExtremelySugaoEffect：360° capsulorhexis can be completed in 1 second.，Using a semiconductor-pumped solid-state femtosecond laser specifically designed for cataract surgery, with a pulse width of less than 600 femtoseconds and a pulse frequency of up to 120kHz.To simultaneously ensure the speed of capsulotomy and the smoothness of the capsulotomy edge, while minimizing the risks of incomplete capsulotomy or capsular tear caused by patient eye movement or liquefied cortex overflow during the laser emission process.

Hydrating Comfort Experience：Adopting InnovationNewAqueous Patient Interface Technology，The part that comes into contact with the eye is made of aqueous material or design, which can better fit the surface of the eyeball during the operation.Reduce corneal endothelial damage,Reduced during the surgical procedureSubconjunctival hemorrhage improved the patient's comfort.

In addition, the productUsing panoramic, three-dimensional, high-resolution OCT, with >10000Axial scanning,Enables precise positioning, making surgical procedures more accurate.。

# Clinical Application

First Case of Surgery Completed

Professor Zhu Xiangjia, Director of the Cataract and Lens Refractive Surgery Department, performed the first surgery. The patient, Ms. Wang (66 years old), had nuclear cataracts in both eyes.EndophthalmitisAstigmatism, with uncorrected visual acuity of only 0.03 in the right eye.

Professor Zhu's team completed the procedure using the "Catalys WhiteStar 7th Generation" femtosecond laser.5.3mm diameter precise capsulorhexis, 5.9mm diameter pre-chopping significantly reduce phacoemulsification energy and time.; Without the need for an external navigation system, the toric IOL laser marking function was applied, and a trifocal toric intraocular lens was implanted. The surgery proceeded smoothly throughout, providing a one-stop solution for cataracts, presbyopia, and astigmatism.

On the first day after surgery, the patient's right eye vision was 1.0-1.0-1.0 for distance, intermediate, and near, with an intraocular pressure of 11mmHg, and reported very clear vision.

Clinical Research Results

Research data on femtosecond-assisted cataract surgery shows that, under the premise of similar clinical outcomes,The average capsulotomy time for the LenSAR group (Lensar company) was 3 seconds, while for the LenSx group (Alcon) it was 13 seconds.Catalys (Johnson & Johnson) only needs0.9 seconds. InA large clinical study evaluating 1000 eyesCatalys can achieve a 99.8% complete capsulotomy.

A prospective randomized controlled clinical study showed,Catalys® System in Cataract PatientsCan reduce the total effective phacoemulsification time by 96%.；The incision of Catalys® is a non-flattening aqueous interface, which does not cause corneal wrinkles when docking with the eyeball. Patients experience greater comfort, the cornea maintains its natural curvature, and there is less conjunctival bleeding; it does not interfere with laser transmission, resulting in a capsulotomy success rate of over 99%.

Another studyTreatment of 50 patients (mean age 69.9 ± 8.61 years) with bilateral cataracts using the Catalys or LenSx laser systems revealed no statistically significant differences between the two groups in terms of patient interface preparation time, number of docking attempts, effective phacoemulsification time, mean phacoemulsification power, total ultrasound time, and nucleus removal time. However,Compared with the Catalys group, the LenSx group showed a longer cortex removal time as well as higher levels of pressure sensation and vision loss (p<0.001).。More eyes in the Catalys group achieved complete capsulotomy (p<0.001), and cortex removal was also easier.The postoperative visual acuity, corneal curvature, endothelial cell count, and intraocular pressure were comparable between the two groups.

Patients in the LenSx group perceived significantly higher levels of pressure and vision loss.Catalys Group
