Advanced Technology IOLs

During cataract surgery, the surgeon traditionally implants a standard monofocal lens that provides excellent vision. A standard replacement lens cannot compensate for loss of accommodation due to presbyopia, so those who opt for this type of replacement lens usually need glasses to improve near vision or to fine-tune distance vision. Most standard lens recipients are happy with their choice.

Is there an alternative to the standard replacement lens?

For many people, the answer is YES. Revolutionary technology makes it possible to take vision correction to a new level by restoring youthful ability to focus on objects at varying distances. If it is important for you to be less dependent on reading glasses or bifocals, you may want to consider an advanced technology replacement lens implant. These lenses are designed to provide sharper vision with less reliance on glasses or contacts.

Which replacement lens is right for me?

This question can be answered only after careful consideration of the health of your eyes, your individual lifestyle, and the demands of your occupation and hobbies. For cataract patients, the choice is between a standard lens plus glasses or an advanced technology replacement lens implant that may help them recapture a full range of quality vision with less dependence on corrective lenses.

Before advising you, your eye surgeon will want to know more about:

  • The kind of work you do
  • How many hours a day you read and what types of reading you do
  • How many hours a day you spend using a computer
  • The types of outdoor activities you enjoy
  • Your hobbies, and whether you do close work like sewing or knitting
  • How much driving you do at night
  • Whether you like to travel
  • How bothered you are by wearing glasses

Ultimately, the decision is yours. Ask yourself, “What would my life be like if I was less dependent on glasses?” If you opt for an advanced technology replacement lens implant, your surgeon will select the technology that best meets the visual demands you face.

What are the brand names of the lenses that my surgeon may recommend?

symfony-lens-tecnisDrs. Del Negro, Senft, and Glatman may recommend a TECNIS® advanced technology replacement lens implant. The TECNIS lens is designed to enhance a full range of vision (near, far, and in-between). The Symfony and Symfony Toric Continuous Range of Vision Lenses correct at near, intermediate, and distance and provide continuous high-quality vision for patients favoring intermediate and longer reading distances for activities such as computer work and magazine reading.

Your surgeon will carefully evaluate the visual demands of your individual lifestyle before recommending a particular lens. If you have astigmatism, your surgeon may recommend a Toric or Symfony Toric lens designed to correct that condition. There are circumstances where another lens option may be more beneficial for a particular patient. All options would be discussed during your exam.

TECNIS®: Is it possible to achieve a full range of vision…without glasses?

25_TECNIS_Multifocal_IOLThis +2.75 D multifocal lens delivers enhanced performance at 50 cm theoretical reading distance.

  • Outstanding vision across all distances (near, intermediate and far)
  • Enhanced performance for those favoring longer intermediate-vision activities such as reading labels while grocery shopping
  • 98% of patients reported an ability to function comfortably without glasses at intermediate and far distances1
  • 97% of patients reported they would have the same IOL implanted again*
  • The TECNIS Family of 1-Piece Multifocal intraocular lenses also offer higher-power, advanced technology implants for reading. Your personal preference, lifestyle, and overall eye health will determine which lens is right for you.

In general, your surgeon will carefully evaluate the visual demands of your individual lifestyle before recommending a particular lens. If you have astigmatism, your surgeon may recommend a “toric” lens designed to correct that condition.

Toric®: Can my astigmatism be corrected at the time of cataract surgery?

Toric-Lens-2A person who has both a cataract and corneal astigmatism will not regain quality distance vision after cataract surgery unless the astigmatism is also corrected. The Toric lens makes it possible to correct astigmatism and cataracts at the same time and provides quality distance vision. Its unique design makes it possible to reduce, or eliminate, corneal astigmatism and significantly improve uncorrected distance vision.

Who should consider having an advanced technology replacement lens implanted?

Candidates for these advanced-technology lenses include patients age 45 or older who desire a full range of vision in each eye with less dependence on reading glasses or bifocals, as well as individuals with cataracts that impair vision. Patients with health problems, such as diabetes or a chronic infection, should wait until those conditions are under control before scheduling the procedure.

Your doctor will perform a careful examination before making any recommendation.

A-Scan IOL Master

IOLMaster® 500, Image courtesy of ZEISS

The IOLMaster and/or A-Scan is a type of diagnostic test used in ophthalmology to measure the length of the eye. The IOLMaster, all-in-one testing device, measures the axial length and keratometry as well as IOL (intraocular lens) power. The IOLMaster provides all biometric parameters required for IOL power calculation and lens selection for cataract surgery. The most common use of the A-Scan is to determine eye length for calculation of IOL (intraocular lens) power for cataract surgery. When a cataract is removed, the lens is replaced by an artificial lens implant. By measuring both the length of the eye and the power of the cornea (keratometry), a simple formula can be used to calculate the power of the intraocular lens needed. There are several different formulas that can be used depending on the actual characteristics of the eye. This test is also utilized during a patient’s LASIK Consultation to determine the white-to-white measurements that are needed to complete the customized surgical plan.

Fluorescein Angiography

Dr. Glatman utilizes fluorescein angiography to aid in the diagnosis and management of various conditions that may occur in the retina. Pictures taken after the dye is injected help pinpoint signs of retinal circulation problems, swelling, leakage, or abnormal blood vessel formation, which helps guide treatment.

Focal Laser

Focal Laser is used by Dr. Glatman to treat Diabetic Macular Edema. During the treatment, a laser beam is used to seal the leaking blood vessels near the macula. In time, the swelling in this area decreases, as a result of the laser treatment, leading to improved visual acuity.

Lenstar: The All-in-One Optical Biometer


The Lenstar LS 900 Biometer is a non-invasive, non-contact OLCR (Optical Low Coherence Reflectometry) device. It is used for obtaining ocular measurements and performing calculations to assist in the determination of the appropriate power and type of IOL (intraocular lens) for implantation after removal of the natural crystalline lens following cataract removal.

The LENSTAR measures:

  • Axial eye length
  • Corneal thickness
  • Anterior chamber depth
  • Aqueous depth
  • Lens thickness
  • Radii of curvature of flat and steep meridian
  • Axis of the flat meridian
  • White-to-white distance
  • Pupil diameter

The Lenstar provides highly accurate laser optic measurements for every section of the eye − from the cornea to the retina − and is the first optical biometer on the market that can measure the thickness of the crystalline lens. With a special calculation method, the Lenstar provides the user with the best possible IOL prediction.

It provides reliable and precise measurements for the K values, axis, and astigmatism that are essential to the sophisticated planning of Toric and presbyopia correcting lenses. The Lenstar offers the optimal planning platform for superior refractive outcomes in cataract surgery, both now and in the future. Lenstar is redefining optical coherence biometry.

In a single measurement scan and using optical low coherence reflectometry (OLCR), Lenstar captures axial dimensions of all of the human eye’s optical structures. Additionally, Lenstar measures corneal curvature, white-to-white and more.

LenSx® Laser (Laser Custom Cataract Surgery)

lensx-del-negro-senft-eye-associatesNo matter what you value most in life – working, reading, golfing, watching your children or grandchildren, or just taking in the scenery – the level of enjoyment you get out of those activities is very dependent on your sight. If your vision is clouded by cataracts, you may be limited in enjoying the things that are most important to you. Cataract surgery can significantly improve your quality of life.

When you choose cataract surgery with Drs. Del Negro, Senft, and Glatman, we make sure you have the best and most advanced options available to you. That’s why we are excited to be the first eye surgeons in the area to offer Laser Cataract Surgery to provide our patients the opportunity to achieve their best possible vision.

What is the LenSx® Laser?

The LenSx® laser is a femtosecond laser that gives Drs. Del Negro, Senft, and Glatman computer controlled precision, allowing more accurate performance of some of the key steps of cataract surgery. Using a variety of highly advanced technologies, the LenSx captures precise, high resolution images of your eye. To further enhance accuracy, a patient interface connects your eye to the image-guided unit so that the LenSx laser computer and the surgeon commanding it have precise, real time images of your eye at all times during the procedure. These images allow the surgeon to accurately guide the laser in performing cataract surgery with a level of precision not previously possible.

Customized to Your Eyes

All human eyes may share the same basic anatomic structure, but every eye is unique in terms of size, depth and curvature of the cornea, size of the lens, and length of the eye. These parameters are carefully measured and mapped prior to surgery. The LenSx laser uses optical coherence tomography to capture the precise, high resolution images of your eye. This, along with the information obtained prior to surgery, allows Drs. Del Negro, Senft, and Glatman to plan and perform surgery specific to each eye.

With standard cataract surgery, the incision is made with a blade and access to the cataract is obtained using a needle. Not only does the LenSx laser create extremely precise cataract incisions and break up the cloudy lens for easier removal, it also provides the surgeons with the ability to correct/improve astigmatism with more accuracy and precision than ever before.

Gentle, accurate, and precise, the LenSx laser gives Drs. Del Negro, Senft, and Glatman the ability to perform blade-free cataract surgery. This allows for the best possible effective positioning of the advanced technology lens replacement implants and provides the patient with the most predictable post operative visual results.

The Advantages Are Clear

  • The femtosecond laser makes more precise incisions when compared to the traditional method.
  • The LenSx laser technology gives Drs. Del Negro, Senft, and Glatman the ability to reduce astigmatism with greater accuracy. This allows for better performance of the advanced technology lenses and, ultimately, provides the best possible visual outcome.
  • Laser precision creates a uniform, circular opening in the capsular bag that is perfectly centered; this is critical for effective lens position to ensure your best visual outcome.
Magellan – Corneal Topographer

This screening device automatically provides an assessment of normal and abnormal corneal states. It displays percentage similarities of disorders, increasing awareness of borderline diseases such as: Keratoconus (KC), Keratoconus Suspect (KCS), Pellucid Marginal Degeneration (PMD), Astigmatism (AST), Myopic Refractive Surgery (MRS), Hyperopic Refractive Surgery (HRS), and Penetrating Keratoplasty (PKP). Primarily, Dr. Senft uses this screening to rule out any condition that would make a patient ineligible for PRK or Bladeless LASIK. 

Micropulse Laser Trabeculoplasty (MLT)

mlt-del-negro-senft-eye-associatesIndications- The Micropulse Laser Trabeculoplasty surgeries are used for patients with open angle glaucoma. The laser is utilizes to treat the drainage system of the eye known as the trabecular meshwork. Treating this area of the natural internal draining system is designed to improve the outflow of fluid from the eye.

This type of laser surgery will be effective in some patients but not others. Your response is determined by the type of glaucoma you have and the specific structures found in your drainage system. Your doctor cannot predict how well the laser will work before the laser surgery.

Procedure- The laser machine is similar to the examination microscope that the Ophthalmologist uses at each visit to look into your eyes. The laser itself makes little noise and flashes a light about as bright as the flash on a camera. Nearly all patients find the procedure comfortable and pain free. The procedure generally takes 10 – 20 minutes.

Medications- You may need to use drops both before and after the laser treatment. As the pressure in the eye may temporarily go up after laser treatment, you will likely need to have your pressure measured after the laser surgery. If the pressure does elevate, you may need additional medicines to lower the pressure, which will be administered in the office. Rarely, the pressure in the eye could elevate to a level that may require surgery in the operating room to relieve the glaucoma. You need to use drops after the laser to help the eye heal correctly. In most cases you will be asked to continue your other glaucoma medications after the laser surgery. The doctor will notify you if there are exceptions to continuing your medications.

Risks and complications- Glaucoma laser surgery may be followed by complications. Most patients notice some blurring of their vision after laser surgery. This generally clears within a few hours. The chance of your vision being permanently affected by this laser is very, very small. Although rare and unusual, there may be bleeding within the eye, inflammation, cataract and increase in the pressure in the eye requiring different and more extensive treatment. It will take several weeks to determine how much of your eye pressure will be lowered with this treatment. You may require additional laser surgery to lower the pressure.

OPD Scan (Optical Coherence Tomography)


At Del Negro & Senft Eye Associates, we use the innovative OPD III Wavefront system. This remarkable instrument uses the most advanced digital technology available to help us better evaluate your unique needs and provide you with the best possible vision. Far more than just a refractive examination, this instrument gives us a comprehensive understanding of your complete visual system and optical pathway.Using information from the OPD III Wavefront system, we can make better recommendations to help you see better in all types of settings.

How Is Your Current Vision?

  • Trouble with excessive glare and less than optimal vision when driving at night?
  • Feel like you just aren’t seeing your best with your latest pair of glasses?
  • Think cataracts are impacting your vision?

OPD testing can provide insights that contribute to developing a proper treatment plan. We are thrilled to offer the best technology and care for our patients. Our job is to provide you with your best possible vision.

The OPD-Scan III performs at least five important clinical functions:

Optos – Retinal Photography


Annual eye exams are vital to maintaining your vision and overall health. Our doctors offer the optomap® as an important part of our eye exams. The first time a new patient is seen in the office our doctors dilate as normal, establishing a baseline. Following this initial dilated exam, a welcome benefit to our patients is that that a routine exam can be performed without dilation, if there are no additional findings to suggest otherwise. The optomap produces an image that is unique and provides Drs. Del Negro, Senft, Glatman, Shah, and Carniglia with a high-resolution 200° image in order to ascertain the health of your retina. This is much wider than a traditional 45° image.

Many eye problems can develop without you knowing, in fact, you may not even notice any change in your sight – fortunately, diseases or damage such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.

The inclusion of optomap as part of a comprehensive eye exam provides:

  • A scan to show a healthy eye or detect disease.
  • A view of the retina, giving your doctor a more comprehensive view than they can get by other means.
  • The opportunity for you to view and discuss the optomap image of your eye with your doctor at the time of your exam.
  • A permanent record for your file, which allows our doctors to view your images with you each year to look for changes.

The optomap is fast, easy, and comfortable for anyone. The entire image process is simple--you just look into the device one eye at a time.

pentacam-del-negro-senft-eye-associates-2A rotating Scheimpflug camera captures multiple, high resolution images providing valuable information on Refractive, Cataract, Glaucoma, and Corneal findings. Within a mere second the Pentacam® supplies our doctors with precise diagnostic data on the entire anterior eye segment. For those diagnosed with a cataract, the degree of cataract is made visible by the light scattering properties of the eye lens. Measurement of the anterior and posterior corneal surfaces supplies the true total refractive power of the cornea. The data on the posterior surface provides information needed for early keratoconus detection, a test Dr. Senft orders to determine if a patient is a candidate for LASIK. The rotating scan supplies more data points in the centre of the cornea. Corneal thickness is also measured to determine if the amount of tissue is more appropriate for PRK or Bladeless LASIK. For added accuracy, a supplementary pupil camera corrects for eye movement during the examination. Pentacam.com

spectralis-del-negro-senft-eye-associatesDel Negro & Senft Eye Associates is making a difference in the community fight against sight-stealing eye diseases, such as glaucoma and macular degeneration (AMD). It is well known that the key to preventing vision loss is early detection. With the new addition of this 3-D imaging technology, our doctors are now better able to detect and manage glaucoma and retinal disease such as macular degeneration and diabetic retinopathy.This new system, known as SPECTRALIS, uses an advanced eye tracking system that produces 3-D images of the eye, allowing our doctors to more easily identify change over time. This helps reveal eye disease which may not yet be noticeable by the patient or detectable with a traditional visual exam. The SPECTRALIS not only aids in the detection of such diseases as glaucoma and macular degeneration, it also provides essential information for monitoring them in follow-up examinations.

The SPECTRALIS exam is fast, safe and usually does not require dilating the eye. While a patient comfortably sits in a stationary position, the eye is scanned in a few seconds.

SPECTRALIS offers TruTrack™ active eye tracking, and BluePeak™ blue laser autofluorescence, providing clinicians with unique views of the structure and function of the eye.

Enhanced image detail comes from Heidelberg Noise Reduction™, which improves images like Dolby® noise reduction improves recorded sound. Measuring change with 1 micron reproducibility is possible with AutoRescan™, which automatically places follow-up scans in precisely the same location, bypassing operator variability. This precision is the product of 20 years of proven HRT technology, which paved the way for the dual-beam approach to imaging.
