CATARACT TECHNIQUE

Drishti Eye Centre has always been the torchbearer for established techniques. In early 1980s, Dr.M.C Luthra, the founder, was one of the pioneers of Intra Ocular Lens Implantation in the country.

Phacoemulsification is the technique, which is being used for more than a decade. The cataract procedure and its techniques have evolved dramatically improving vision in up to 99% of cases and saving millions from cataract-induced blindness.

Cataract Treatment with phacoemulsification is performed on an outpatient basis under topical or regional anesthesia. Paracaine eye drops are used to numb the eye. No injection is given to numb the eye. No patch is required after surgery. The patients can see and move their eyes after surgery. Topical anesthesia has innumerable advantages.

1. There are no risks which are sometimes associated with regional anesthesia.

2. There is improved vision almost immediately after surgery.

3. This type of anesthesia is most helpful to cataract patients with sight in only one eye.

A small incision, less than 3mm, incision is made. Special microsurgical instruments are used to break up and suck the lens fragments from the eye (phacoemulsification). The back portion of the lens capsule is left in place and polished for clarity.

A small foldable intraocular lens is inserted through the wound and unfolded in place of the natural lens. The incision is self-sealing so that no stitches are needed. The no stitch incision is used because it can seal itself after Cataract Treatment without stitches, which allows the eye to heal more naturally and with greater symmetry.

The phacoemulsification technique is carried out as an outpatient procedure in stress free environment. The patients are informed about the details of the procedure. This helps in making the patient more comfortable. The patient is encouraged to bring the friends & relatives so that the apprehensions get allayed.

The surgical experience & the recovery becomes a better experience. The attendants of the patients are witness to the details of the procedure as they are able to watch on the LCD monitor. The state-of-the-art surgical methods allow people to return home shortly after the procedure to continue with their regular routines.
The total stay in the Institute is for 2-3 hours.
 

CATARACT TECHNOLOGY

TorSional Phacoemulsidication with Infiniti Vision System is the most advanced Phacoemulsification technology in the world for cataract surgery. Torsional Emulsification is a much safer & efficient technique as compared with the traditional phacoemulsification technique. This advanced state-of-the–art technology has changed the very perspective of phacoemulsification.

At Drishti eye Centre, the effort is to give the best results. Calculation of the power of intra Ocular lens is another important click in achieving the power of the spectacles which the patient would have to use after the surgery.

No worry for Cataract Patients with history of Refractive Surgery (PRK/Lasik) Drishti Eye Centre offers fool proof methodology for calculating the power of Intra Ocular Lens to be used

Cataract surgery has come of age. Drishti eye centre offers the best customized treatment for each patient. This helps in improving patients’ quality of life they deserve.

The customized cataract surgery involves the following aspects.

Every patient has different visual requirements. These requirements are based on the professional & personal visual goals of the patient.

We at Drishti Eye Centre strive to give to the patient quality and quantity of vision keeping in mind the individual goals. This is possible because of the state-of-the-art capacity of the institute to raise the bar in cataract surgery. We tailor our surgical capability to help the patient achieve any of the following goals:
 

• Spectacle free eye after cataract surgery.

• Attaining post operative spectacle power of the eye as per the requirement of the patient.

• Implanting Intra ocular Lenses having different qualities like:

  • Image Quality

  • Blue light protection to mimic a natural lens of a 20 year old

  • Multifocality provides patients with freedom from glasses

  • Toricity delivers precise astigmatic correction & distance vision spectacle freedo.

  • Protection of the weak Retina by not allowing the posterior capsule to opacify

• Using different Phacoemulsification techniques according to the type of the cataract.

• Instant & planned appointment for cataract surgery as per the convenience of the patient.

Described as a natural clouding of the eye lens, cataracts are pretty common, affecting about 20 million people worldwide¹.

Cataracts are actually considered an inevitable part of aging and are widespread among people ages 55 years and older. In fact, half of all Americans have them—or have had cataract surgery—by age 80. In other words, if you live long enough, you will likely develop cataracts.

What's worse, if left untreated, cataracts can lead to blindness. Cataracts are already the leading cause of vision loss in adults over age 55 and the most common cause behind blindness worldwide. (For more, see What Are Cataracts?)

The good news, however, is that treatment for cataracts is successful; more than 97 percent of the 3 million-plus cataract surgeries performed each year in the United States are considered successful.

In fact, about 95 percent of patients are able to restore their full pre-cataract distance vision after undergoing the standard intraocular lens (IOL) procedure

Causes of Cataract

Many things can cause a cataract to form, including diabetes, but it is believed that natural aging is the main culprit—at least for 99 percent of cataract sufferers (the other 1 percent are born with congenital cataracts, sometimes due to metabolic disorders or intrauterine infections). For the majority of people with age-related cataracts, age-related cataracts : A clouding of the eye's lens that blocks passage of light to the retina, resulting in impaired vision. Often a result of normal aging, cataracts form when protein clumps cloud areas of the eye's lens. As the cataract progresses, vision worsens and often requires surgical replacement of the damaged lens with an artificial one. or acquired cataracts, these develop very slowly and painlessly over the years and are often initially discovered by an eye doctor during routine exams, but may not be treated until your cataract impedes upon daily activities.

Types of Cataracts

To understand exactly how and why a cataract forms, you first need to know what kind of cataract it is. Following is a breakdown of the 3 most common.

Nuclear cataracts

The most common type, nuclear cataracts are associated with nearsightedness, blurry vision, and faded colors. As a nuclear cataract develops, the eye's lens Lens: The transparent disc behind the pupil that brings light into focus on the retina. becomes more curved and worsens nearsightedness, sometimes temporarily improving farsightedness but not for long

Attributed as a consequence of natural aging, there are several reasons why nuclear cataracts form.

• Just as skin sheds, so does the eye. But since cells can’t be lost into the air inside the eye, they deposit into the lens, causing it to thicken and yellow.

• Likewise, with aging, fewer nutrients reach the inner eye, contributing to the formation of an opaque nucleus.

• Overexposure to ultraviolet light can also contribute, especially as the lens becomes harder, less resilient, and more opaque over time.

• Several studies have also linked alcohol and exposure to cigarette smoke as cataract contributors.

• Some systemic disorders, such as hypothyroidism (an underactive thyroid disease), diabetes, and in rare cases, glaucoma, can lead to cataracts as well.

Cortical cataracts

Often associated with farsightedness and natural aging, cortical cataracts are less common and tend to develop in their own unique way.
​

• They form when the shell, or cortex, of the lens becomes hard after developing post-birth and grows, usually till around age 60, when nearly 16 percent of the lens has become cortex.

• Cortical production makes the lens more compact and hard, or sclerotic. Sclerotic: Relating to sclerosis, the hardening of tissue.
  Posterior subcapsular cataracts Posterior subcapsular cataracts are even less common but affect vision more than any other type and tend to affect people under age 40 more often.

Since light converges at the back of the lens, extreme sensitivity to bright lights normally develops and reading can be extremely difficult. Causes include:

• Chronic intraocular inflammation due to overuse of medications such as corticosteroids. Corticosteroids: A class of steroid hormones used to treat a variety of conditions. Chronic use may lead to the formation of posterior subcapsular cataracts.

• A penetrating injury to the lens, eye surgery, concussion, or the use of irradiation to treat an eye tumor, can cause any type of cataract but typically result in posterior subcapsular cataracts

Cataract prevention

While many doctors believe that nothing prevents most cataracts from forming, there is some promising research and things you can start doing now for possible cataract prevention (if you don’t have them already) or to slow down the development of a cataract. Such as:

• Wear sunglasses to block out the harmful ultraviolet (UV) rays from sunlight. Too much exposure has been shown to contribute to the development of cataracts. Look for a label from the American National Standards Institute (ANSI) that says that the lenses block both UVA and UVB rays.

• Eat foods containing high amounts of antioxidants, meaning fruits and vegetables. People who eat large amounts of green, leafy vegetables, such as kale and spinach, which are rich in the nutrients lutein and zeaxanthin, show a lower risk for cataracts.

• Has your cholesterol been checked by your doctor? It could be that there is a link between high cholesterol levels and cataracts, as some studies suggest that the use of statins, a class of cholesterol-lowering drugs, may help prevent the formation of nuclear cataracts. Anyway, it doesn’t hurt to get your cholesterol levels tested by a doctor at least every 5 years, or more often if you have had high levels in the past or are a man over age 45 or a woman over age 50.
