Unveiling the 'Flying White'! How to solve the "hard bone" of cataracts?

Mr. Yan, 42, was engaged in construction work due to ultra-high myopia of more than 2,000 degrees in both eyes and cataracts......

Dr. Li, 73, was a former otolaryngist and lived a life of playing with his grandchildren and reading newspapers after retirement. As he ages, cataracts gradually worsen, and his vision in both eyes continues to decline, and he can't even make milk powder for his grandson to see the scale of the bottle......

Fortunately, there is a surgery that does not require a "knife" - femtosecond laser cataract surgery, which can not only help cataract patients regain their clear vision, but also meet their desire to "see and see clearly". At the same time, personalized and precise surgical plans are provided for some patients with complex eye conditions. It can be said that precision refractive cataract surgery and femtosecond laser-assisted cataract surgery technology can be described as a major upgrade in the industry.

Meet femtoseconds

The femtosecond laser acts on the eyeball with a pulse width of the order of femtoseconds, using digital computer control, which can replace the doctor's manual operation in just a few seconds, with high accuracy and strong personalization, and easily complete the core steps such as corneal incision, anterior capsular tearing, and pre-cleavage, avoiding manual operation errors, and the size and position of the capsule tearing are just right, making the intraocular lens more accurate and stable, and ensuring that the subsequent implanted intraocular lens maintains a stable level and then plays a role.

"Flying white" can better solve many "hard bones"

"When encountering some intractable cataracts, doctors are required to have higher surgical skills, so the use of computer-controlled and parameter-set femtosecond laser cataract surgery can narrow the surgical safety gap caused by poor experience among doctors," said Tan Yongchang, director of the Cataract Department of Dongguan Aier Eye Hospital.

Cataract surgery with high myopia is a complex cataract surgery, which is more difficult and risky. Axial high myopia (axial axis exceeding 24 mm) affects the surgeon's judgment on the diameter of the capsule tear due to the length of the eye axis, the depth of the anterior chamber, the large capsule of the lens and the relaxation of the suspensory ligament, which affects the surgeon's judgment of the diameter of the capsule.

Diabetic patients have a fragile eye foundation, are more sensitive to surgical stimuli, and heal more slowly after surgery. During surgery, some links are assisted by femtosecond lasers, which can effectively reduce the hardness of the lens nucleus. Subsequent phacoemulsification of the lens nucleus can greatly shorten the time and reduce the cumulative release of energy. Protect the eye tissue of diabetic people and ensure better postoperative recovery.

The use of this technique in patients with scleronuclear cataract can reduce the effective phacoemulsification time and energy, reduce corneal edema in the early postoperative period, and reduce the rate of corneal endothelial cell loss.

It has obvious advantages for shallow anterior chamber and all-white cataracts that are difficult to operate manually.

For patients with lens subluxation such as Marfan syndrome, femtosecond laser-assisted in situ anterior lens capsulotomy and laser cleavage can minimize the operation-induced damage to the suspensory ligament, and the surgery is safer.

The lens is completely opacity caused by rupture of the anterior capsule of the lens or blunt contusion of the eye caused by corneal penetration, and the use of femtosecond laser can achieve repeated capsule tearing, reducing the difficulty of surgery and improving surgical safety.

Director Tan Yongchang said that femtosecond laser cataract surgery is digitally controlled, and this innovative surgical method allows ophthalmologists to use femtosecond laser instead of manual use of instruments such as scalpels to complete the most challenging and delicate steps in cataract surgery. In addition to solving difficult conditions, it is also very suitable for patients who choose to implant functional intraocular lenses, and a perfect anterior lens incision can ensure that the intraocular lens is centered and more stable, and may achieve better results.

Keep up with the cutting edge and trust the choice

Since femtosecond laser cataract surgery officially entered China in 2013, Aier Ophthalmology is one of the earliest professional ophthalmic medical institutions to carry out this operation.

Since the introduction of femtosecond laser cataract equipment in Dongguan Aier Eye Hospital in 2019, there have been more than 2,000 cases so far, and it has been trusted by more and more middle-aged and elderly friends. It has been awarded the honors of "Global Outstanding Surgical Expert in Precision Femtosecond Cataract Surgery", "Global Precision Femtosecond Cataract Surgery Excellence Service Center", and "Femtosecond Laser Cataract Surgery Excellence Demonstration Center".

The cataract specialty of Dongguan Aier Eye Hospital has been deeply involved in the field of ophthalmology for more than ten years, closely following the cutting-edge technological achievements of cataract specialty, led by experts such as President Liu Fei and Director Tan Yongchang, and forming a team of physicians with rich clinical experience to continue to protect the clear vision for citizens and friends in Dongguan and even the Bay Area.
