Cataract

A clouding or loss of transparency of the lens in the eye as a result of tissue breakdown and protein clumping. There are many causes of cataracts, including aging, cortisone medication, trauma, diabetes, and other diseases. Cataracts affect most people who live into old age. Symptoms include double or blurred vision and sensitivity to light and glare. An Ophthalmologist can diagnose cataracts by examining the eyes with Slit Lamp and various other diagnostic equipment and suggest you the best treatment possible-Cataract surgery-MICS/phacoemulsification surgery (PHACO)

What is Cataract?

A cataract is a clouding of the eye’s naturally clear lens. When the lens becomes cloudy, light rays cannot pass through it easily, and vision is blurred.

Common symptoms of cataract include

A painless blurring of vision
Glare or light sensitivity
Poor night vision
Double vision in one eye

When to see a doctor?

Make an appointment for an eye exam if you notice any changes in your vision. If you develop sudden vision changes, such as double vision or flashes of light, sudden eye pain, or sudden headache, see your doctor right away.

What Causes a Cataract?

Medical problems such as diabetes
Injury to the eye
Medications, especially steroids
Long-term, Unprotected exposure to sunlight.
Previous eye surgery
Unknown factors

How is a cataract detected?

A thorough eye examination by your ophthalmologist can detect the presence of a cataract.

How fast does a cataract develop?

How quickly the cataract develops varies among individuals and may even be different between the two eyes.

When should surgery be done?

Surgery should be considered when cataracts cause enough loss of vision to interfere with your daily activities.
It is not true that cataracts need to be “rips” before they can be removed or that they need to be removed just because they are present.

How can a cataract be treated?

There are no medications, eye drops, exercises or glasses that will cause cataract to disappear once they have formed, surgery is the only way to remove a cataract.

What is phacoemulsification cataract surgery?

Phacoemulsification is a non-stich method of cataract removal by ultrasonic fragmentation and aspiration of the cataractous lens through a small wound. It gives greater intraoperative control and faster postoperative recovery. Patients are able to resume normal activity much sooner and with fewer restrictions in a shorter duration of times that the traditional cataract surgery.

What are premium intraocular lenses?

Tonc IOL’s, Multifocal IOL’s. Trifocal IOL’s are various premium intraocular lenses which help in elimination need for glasses following Cataract Surgery.

Types Of Cataracts Include:

A subcapsular cataract occurs at the back of the lens. People with diabetes, high farsightedness or retinitis pigmentosa, or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract.

A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.

A cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortex, which is the part of the lens that surrounds the central nucleus.

Cataract surgery is very successful in restoring vision. In fact, it is the most frequently performed surgery in India. Nine out of 10 people who have cataract surgery regain very good vision, somewhere between 20/20 and 20/40. During surgery, the surgeon will remove your clouded lens and in most cases replace it with a clear, intraocular lens (IOL).New IOLs are being developed all the time to make the surgery less complicated for surgeons and the lenses more helpful to patients.

SRS Eye Hospital is equipped with the state of the art facilities for operating cataract including day care cataract surgeries under topical anaesthesia or local anaesthesia

SRS Eye hospital is equipped with modern operation theatre to ensure a sterile environment during cataract surgery. We have the most advanced phacoemulsification system-Oertli CatarRhex 3(switzerland)and Topcon operating microscope system to perform cataract surgery.

The various surgical options available are:

-Phacoemulsification-Micro Incision Cataract surgery

-Small Incision Cataract Surgery

Types Of Intraocular Lenses(IOL)

Monofocal IOL -A majority of intraocular lenses implanted are monofocal lenses. These lenses have the capability of focusing light from a single distance. Normally distant objects are clear and one requires glasses for reading. The monofocal lenses are either rigid non foldable or foldable. The foldable lenses can be inserted through a small wound allowing faster visual recovery and reduced postoperative discomfort.

Toric IOLs – In certain situations, the patient may have a high cylinder or preoperative bend of the cornea. Monofocal lenses are unable to compensate for this, hence the patient requires glasses for distance vision postoperatively in addition to a reading power. Toric IOLs have the ability to correct the eye power both at the corneal and lenticular plane, thereby correcting the cylindrical power.

Multifocal IOLs -Multifocal lenses have different segments which focus light rays from various distances onto the retina. This affords correction for near, intermediate and distant vision to the patient. Most often patient can manage his activities without glasses for all distances.

The patients are first evaluated in detail clinically about the eye condition. This includes visual acuity assessment, Intra ocular pressure measurement, dilated slit lamp examination to grade the cataract level, Fundus examination to rule out other causes of decreased vision. Once the detailed examination is done the patients are counseled for surgery in terms of types of IOL and the financial aspects of the treatment. We keep in mind the socioeconomic status of the patient and try to give them the best package. We schedule the surgery date as per patients convenience, once scheduled for surgery we go ahead with other routine investigations like blood examination and Blood Pressure measurements. The specific eye investigation includes Biometry (A-scan and Keratometry) to calculate the power of the implant to be placed.
