Recently,Pizhou Shimming Eye HospitalSuccessfully for aCataract patients completedJohnson & Johnson VisionTECNIS Symfony™ Toric IOL with Extended Depth of Focus and Astigmatism CorrectionImplantation. This is the crystal inPizhou Shimming Eye HospitalFirst SuccessClinical Application, alsoFirst Case in County-Level Cities Nationwide, marking a significant breakthrough for Pizhou Shiming Eye Hospital in the field of refractive cataract surgery.
TECNIS Symfony™ Toric IOL isThe World's FirstExtended Depth of Focus Toric Intraocular Lens, specifically designed for cataract patients with astigmatism. This product utilizes the patented "Echelette diffraction grating" technology,Provide full-range continuous vision without dispersion。InOfficially received registration approval from the National Medical Products Administration in October 2023, entering the Chinese market.

# Patient Details and Surgical PlanThe patient is Ms. Zhuo, a 47-year-old woman. Three years ago, Ms. Zhuo began experiencing blurred vision. During a chance visit to accompany a friend to Pizhou Shiming Eye Hospital for an examination, she decided to get checked as well and was diagnosed with early-stage cataracts.Ms. Zhuo said she had previously known some information about cataracts, but didn't expect to develop them so early. As it was still in the early stages of cataracts, her daily life hadn’t been affected yet. However, after more than two years, Ms. Zhuo's vision rapidly deteriorated.Uncorrected visual acuity dropped to 0.12 in the right eye and 0.3 in the left eye, which has seriously affected normal life.。Later, Ms. Zhuo visited Pizhou Shiming Eye Hospital for a follow-up examination. After a detailed check-up, Deputy Director Wang Jinpeng recommended hospitalization for surgery as soon as possible based on the test results and considering various factors such as Ms. Zhuo's age of onset.But Ms. Zhuo was very cautious about where to have the surgery and what kind of surgery to undergo."I've also looked up some information about cataract surgery online and asked many people. Friends recommended that the ophthalmic surgeries at Ming Vision Eye Hospital are excellent. So I came directly!" Ms. Zhuo said, "I'm only 47 years old this year, and my physical condition is very good. My eyes will accompany me for many more years, so I must take good care of them."I hope that after the surgery, I can live freely, and be able to use my phone, read books, and drive with clarity and comfort.。”On the day of admission, the special inspection team of Pizhou Shiming Eye Hospital conducted a comprehensive and detailed preoperative ophthalmic examination for Ms. Zhuo. The hospitalization team strictly evaluated the patient's ocular conditions and test results, and formulated a rigorous surgical design plan for Ms. Zhuo.▲President Yang Jianhua Conducts Preoperative Examination for Patients (Originated fromPizhou Shiming Eye HospitalThe next day, byPizhou Shimming Eye HospitalInvited expert Yang Jianhua, the business dean of Xuzhou Fuxing Ophthalmology Hospital, performed surgery together with Dean Wang Jinpeng for the patient.In less than 10 minutes，The surgical teamSuccessfully completed the "Cataract Phacoemulsification Combined with Implantation of TECNIS Symfony™ Toric IOL for Extended Depth of Focus and Astigmatism Correction"”。To achieve the best postoperative results, every step of the surgery, including the creation of the corneal incision, continuous curvilinear capsulorhexis, phacoemulsification, polishing, intraocular lens implantation, and watertight incision closure, was performed with precision and care.Through this surgery,Resolved Ms. Zhuo's cataracts, presbyopia, and astigmatism in one procedure.On the first day after the surgery, when the eye patch was removed, Ms. Zhuo was overwhelmed with excitement, feeling that her vision had been restored to the quality she experienced in her youth.Uncorrected distant visual acuity of the right eye is 0.8, intermediate visual acuity is 0.8, and near visual acuity reaches 1.0.。▲President Yang Jianhua in surgery (Originated fromPizhou Shiming 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 patients with cataract or presbyopia correction., enabling cataract patients with astigmatism to correct corneal astigmatism while achieving continuous, all-day vision from far to near without blur.
It adopts innovative hydrophobic acrylic material, which canEffectively filter harmful ultraviolet light and reduce optical interference, ensuring nighttime driving safety while allowing beneficial blue light to pass through, improving visibility in low-light conditionsVisual 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 post-surgery, but patients still need to rely on reading glasses or myopia glasses. After implantation of a bifocal Toric lens, clear distance and near vision can be obtained, but intermediate vision is less satisfactory. However, the patient population often has more scenarios requiring intermediate vision, such as daily cooking and computer use, which are not adequately addressed.Trifocal Toric provides clear far, intermediate, and near vision post-surgery., which are favored by patients, but different trifocal intraocular lenses have different tolerance for astigmatism, with stricter overall requirements, and the residual astigmatism post-surgery is required to 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 features clinically proven long-term stability, refractive stability, and rotational stability, 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 advanced 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
