Laser for cataract & corneal procedures gets 510(k) clearance

Posted on byHTH华体会

The U.S. Food and Drug Administration granted 510(k) clearance to the Victus femtosecond laser platform, designed to be used in both cataract and corneal procedures, according to a news release from Bausch + Lomb and Technolas Perfect Vision.

该释放称，该平台被清除用于创建角膜皮瓣进行LASIK手术或其他治疗方法，需要在白内障手术期间对角膜和前囊切开术进行初始层状切除。

“白内障手术以传统形式可提供出色的效果，并且可以说是体内任何地方进行的最安全，最成功的外科手术之一。我很荣幸能成为进一步改善白内障手术结果的机会。

该版本称，与手动白内障手术技术相比，Victus平台可以通过允许更精确，可控制和中心的囊膜切开术提供更高的精度。

“The Victus platform represents a major advancement for ophthalmic surgeons that can potentially enhance patient outcomes,” Kristian Hohla, PhD, chief executive officer of Technolas, said in the release. “We look forward to the continued commercialization of the technology around the world, so that ophthalmic surgeons can experience its potential for themselves.”

该平台于12月在欧洲获得了CE Mark的批准，现在可以在美国发货。两家公司计划向FDA提交其他迹象。

Getting the Most out of Three IOLs

Posted on byHTH华体会

“The aspheric design of this multifocal IOL enhances patients’ outcomes”, says Elizabeth A. Davis, MD. “There are a number of different IOLs to choose from to achieve the best outcome for patients today. Presbyopic correction lenses are now available and with good results. In many cases, surgeons prefer the Tecnis Multifocal IOL (Abbott Medical Optics Inc. [AMO]) based on their design and positive outcomes.”

In assessing any IOL, you must consider several factors: ease of implantation, predictability of refractive outcome, quality of vision, range of focus (spectacle independence), patients’ satisfaction, side effects, and long-term stability.

The Tecnis Multifocal IOL is based on an aspheric optic design meant to reduce the spherical aberration of an average cornea to zero. The Tecnis Multifocal has a full-diffractive posterior surface, which makes the diffractive optics pupil independent for optimal image quality at all distances under any lighting condition. The optic is made of acrylic and comes in both a one- and three-piece design. The frosted edge also minimizes edge glare.

In a clinical trial, 94.6{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of subjects implanted bilaterally with the lens reported being satisfied with their vision. Also at 1 year, 92.1{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of the subjects had 20/25 or better distance UCVA and saw 20/32 or better at near with distance correction in place. More than 86{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of subjects reported never wearing glasses, and slightly less than 90{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} were able to function comfortably without glasses at all distances (96.9{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at near, 89.7{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at intermediate, and 95.5{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at distance).Only 1{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} always wore glasses.

All multifocal IOLs inherently reduce contrast and induce some amount of glare and halos, it is important to inform all patients that they should anticipate such side effects. Achieving optimal refractive outcomes with the Tecnis Multifocal IOL requires careful preoperative, intraoperative, and postoperative care. Preoperative preparation requires optimization of the ocular surface, a thorough examination to exclude patients with conditions that would preclude good outcomes, and precise biometry and IOL calculations.

To achieve the best results with the lens, it is important to choose appropriate candidates. Certainly, patients should desire reduced dependence on glasses and contact lenses. They should understand not only the risks of cataract surgery in general but the potential side effects of the lens, including reduced contrast, glare, and halos. Either patients should have minimal corneal astigmatism, or the surgeon should have an appropriate method to manage astigmatism. Accurate preoperative keratometric and biometric measurements are critical, and ocular surface disease must be aggressively treated.

Presbyopia-correcting IOLs are one of the most important transforming factors in the practice of anterior segment ophthalmology, and the AcrySof IQ Restor (Alcon Laboratories, Inc.) diffractive multifocal lens is the most commonly implanted presbyopia-correcting IOL in the United States. This technology offers patients visual rehabilitation for functional distance, reading, and intermediate vision. The surgeon’s selection of patients, meticulous attention to detail, and optimization of postoperative results are the keys to successful outcomes with this lens.

激光性白内障手术技术的最新进展可能会使囊核仁糖具有更大的核心和稳定的尺寸，从而可以通过长期纠正的IOL来增强折射结果。具有Iolmaster（Carl Zeiss Meditec，Inc。）或Lenstar LS 900（Haag-Streit AG）和散光的控制精度生物特征量对于最大化结果也是必不可少的。由于必须仔细地将晶状体常数个性化给个别外科医生，因此跟踪术后结果对于完善手术结果至关重要。

Patients are incredibly sensitive to small refractive errors with presbyopia-correcting IOLs, so surgeons must be willing and able to treat them. Astigmatism of greater than 0.50 D in a symptomatic patient requires surgical planning.

在tention to residual refractive error, the ocular surface,2 cystoid macular edema, and the posterior capsule, surgeons can improve appropriate patients’ quality of vision with the AcrySof IQ Restor IOL. The technology has enhanced the quality of life of many pseudophakic patients by reducing or eliminating their need for spectacles. As physicians’ comfort with multifocal lenses improves in the coming years, these IOLs should become more popular, both with cataract and refractive surgeons and their patients.

太阳和白内障

Posted on byHTH华体会

Just like when you have a smear on your sunglasses, having cataracts can feel like the same thing. Ageing is the main reason for the clouding of the eye lens, but excessive UV radiation is another major contributor. The World Health Organization estimates that cataracts account for almost 15 million blind people worldwide. About 20{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974}, or 3 million, of these are most likely caused by UV radiation.

The lens is not solid, instead it is a soft capsule filled with water and protein fiber. The protein fibers are normally crystal clear but can wear out with age. They can become opaque, and UV radiation can also alter the protein prematurely.

Cataract development can be variable amongst individuals regardless of gender or race. The process is generally slow and initially may affect only part of the lens. In some cases it develops from the lens’s rim and grows inside, and in another the lens begins to cloud from the center. In any case, the growing cataract will eventually severely impair vision and frequently lead to blindness.

在早期阶段，白内障被视为滋扰。但是很快需要额外的照明，不同的眼镜和防止眩光的保护。紫外线辐射保护应有助于减慢过程。

Once the cataract interferes too much with the daily life, surgery should be considered. Eye surgeons replace millions of cloudy lenses with substitutes every year, and this safe procedure returns better vision to as much as 90{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of patients.

白内障手术——不断增长的业务

随着时间的推移,眼镜和接触可能不再工作as well to help you see clearly. Contacting an ophthalmologist should always be the first step after noticing any vision changes or impairments. A thorough eye exam can determine the problem and whatvision correction surgeriesare recommended. Cataract surgery is one of the most frequently performed, safest and most successful surgeries in the United States that is covered by insurance.

Many people don’t even recognize the early signs of cataracts, they just know they do not see as good anymore. Some patients begin having早期白内障症状as early as 40. However, cataracts may also develop in those much younger than 40. Most insurance plans pay for cataract surgery procedures using standard lenses, subject to deductibles and co-pays.

Intraocular lensor Smart Lens such as ReSTOR® or CrystaLens®, replace the old lens in an eye. Ultrasound energy is used to remove cataracts. An instrument called aphaco探针is used to remove the natural lens before being replaced with an artificial lens. These premium lenses can almost eliminate the need to wear glasses, both for reading and distance vision.

Cataract surgery is an outpatient procedure and takes just minutes to perform. The advanced technology has grown leaps and bounds and is being performed more and more each year. Most people notice an immediate improvement in their vision following surgery. People resume normal activities the day after surgery. In fact with the new technologies, your dependence on glasses can be greatly reduced or nearly eliminated.
