Recently, inShanghai Xinsj East District Eye Hospital, Ms. Le, Ms. Tian, and Mr. Liang from Malaysia have becomeShanghai's First BatchSuccessfully AcceptedJohnson & Johnson TECNIS Symfony™ Toric IOL Implantation for Extended Depth of Focus and Astigmatism CorrectionPatients.
The surgery was consulted by Professor Yang Jin, Chief Physician of the Ophthalmology Department at the Eye, Ear, Nose and Throat Hospital of Fudan University, and doctoral supervisor, and jointly completed with Dr. Zeng Qiulin from the hospital's Cataract Specialty.
This new productOfficially Put into Use in Shanghai, which will further promote the high-quality development of cataract and astigmatism correction in the Shanghai area.Will help more cataract patients with astigmatism regain continuous dynamic vision without astigmatism throughout the entire range.。

TECNIS Symfony™ Toric IOL isThe World's FirstExtended Depth of Focus Toric Intraocular Lens, alsoIt is the first toric intraocular lens in the Johnson & Johnson Vision TECNIS Symfony family.Specifically designed for patients with cataracts and astigmatism. The product utilizes patented "Echelette diffraction grating" technology,Provide full-range continuous vision without astigmatism。YuOfficially received registration approval from the National Medical Products Administration in October 2023, entering the Chinese market.
The First Batch to Receive TECNIS Symfony™ Toric IOL ImplantationThe three patients faced different eye problems.：The first patient, Mr. Liang, is a 50-year-old international friend from Malaysia. He suffers from unilateral cataracts and has a history of 200-degree hyperopia. His vision declined six months ago, and glasses could not improve it, so he came to the hospital for help.Diagnosed with cataracts after examination, the visual interference while driving at night is very significant."Considering that the patient's contralateral eye is in a hyperopic state, our design plan is to meet his needs for distance and intermediate vision as much as possible after surgery, as well as functional near vision required for basic daily life," said Professor Yang Jin at the surgery site.The second patient, Ms. Le, is aHyperopia, presbyopia, combined with corneal astigmatism and narrow anterior chamber angleElderly female cataract patients, suffering from multiple eye conditions, have difficulty seeing both near and far. They are eager to resolve all issues through a single surgery.The third patient, Ms. Tian, underwent single-eye (left eye) LASIK laser refractive surgery 20 years ago because she was unwilling to wear glasses due to myopia. Her right eye did not undergo surgery because the astigmatism was too severe, and the laser technology for myopia at that time was limited.Myopia and astigmatism in her right eye have troubled her for 20 years.Anisometropia exceeding 300 degrees caused poor binocular stereopsis, preventing her from achieving ideal results in table tennis, a sport she is very passionate about.“The conditions of these three patients' eyes are all very consistent with the indications for the TECNIS Symfony™ Toric IOL.". So he recommended this artificial lens to them," Professor Yang introduced.▲Originated fromShanghai Xinsj East District Eye Hospital# Surgical ImplementationIn the afternoon, Professor Yang Jin and Director Zeng Qiulin jointly performed surgeries on three patients at Shanghai New Vision East District Eye Hospital.The First Batch of TECNIS Symfony™ Toric IOLs Successfully Used in Clinical Practice in Shanghai。It is reported that TECNIS Symfony™ IOL has been on the market in China for 10 years, and a large number of clinical cases have proven this product.Extended Depth of Field (EDOF) IOL shows good postoperative visual outcomes, but in the past treatment process, a small number of cataract patients with more than 1D of corneal astigmatism were unable to have this extended depth-of-focus intraocular lens implanted.TECNIS Symfony™ Toric IOL, as the world's first extended depth of focus (EDOF) intraocular lens, has effectively filled this gap since its market launch.。On the morning of the second day after the surgery, Dr. Zeng Qiulin went to the ward to conduct the first postoperative examination for three patients, including international friends.Mr. Liang's postoperative vision recovered to 1.2 for distance, 1.0 for intermediate, and 0.8 for near vision.；Ms. Le has a distant vision of 1.0, intermediate vision of 0.8, and near vision of 0.5; Ms. Tian has a distant vision of 1.2, intermediate vision of 0.8, and near vision of 0.8.All three patients expressed great satisfaction with the postoperative results.▲Originated fromShanghai Xinsj East District Eye Hospital# TECNIS Symfony™ Toric Intraocular Lens

By combining the EDOF continuous vision crystal patent "Echelette diffraction grating" technology with multifocal crystal technology, this crystal canAchieveFrom 33cm to far distance, providing high-quality continuous vision of 0.8 or above for cataract or presbyopia correction patients, enabling cataract patients with astigmatism to correct corneal astigmatism while achieving continuous, all-day vision from far to intermediate and near distances without blur.
It adopts innovative hydrophobic acrylic material, which canEffectively filter harmful ultraviolet light and reduce optical interference, ensuring safe nighttime driving while allowing beneficial blue light to improve visibility in low-light conditions.Visual quality, providing patients with better circadian rhythms, systemic health, mood, and sleep.
Eye Center of the Second Affiliated Hospital, Zhejiang University School of MedicineTheProfessor Ke YaoSpeaking of: “Currently, there is a very clear classification of toric intraocular lenses for astigmatism correction: single-focus Toric, bifocal Toric, trifocal Toric, and extended depth-of-field Toric.Different Types of Intraocular Lenses Have Their Own Advantages and Disadvantages。After implantation of a single-focus Toric lens, clear distance or near vision can be achieved postoperatively, but patients still need to wear reading glasses or myopia glasses. After implantation of a bifocal Toric lens, clear distance and near vision can be achieved, but intermediate vision is less satisfactory. However, the patient population often has more intermediate vision needs in daily scenarios such as cooking and computer use, which cannot be fully met. A trifocal Toric lens provides clear far, intermediate, and near vision after surgery, making it highly sought after. However, different trifocal intraocular lenses have varying tolerance for astigmatism, with stricter overall requirements, and residual astigmatism post-surgery must be less than 0.75D. Extended depth-of-focus intraocular lenses adopt a diffractive grating design, extending the focal point into a focal line, offering a wide range of vision.As an intraocular lens based on the classic TECNIS platform, it is evaluated from multiple dimensions such as IOL material, optics, and design.TECNIS Symfony™ Toric IOL has long-term stability, refractive stability, and rotational stability with proven clinical validation, along with excellent distance and intermediate vision and unique包容性.(Such as tolerance for postoperative residual astigmatism up to 1.00D, large Kappa angle, refractive error, and tolerance for old age, etc.)Can better balance visual quality and full-range vision, leading to higher postoperative satisfaction among patients.. These are its main advantages, and as a resultOnce entering the market, it was included in the national bulk procurement, laying a solid foundation for its widespread clinical application.。”# About Johnson & Johnson
