Cataract & Refractive Lens Surgery

In India, cataract accounts for 85% of reversible blindness. Surgery is the sole method to remove cataracts, involving the implantation of a foldable lens. At Amita Eye Care, we provide advanced equipment, precise techniques, and a modern infrastructure, serving all segments of society.

What is Cataract?

Cataract is a progressive condition characterized by the gradual clouding of the eye's lens as a result of aging. This clouding inhibits the lens from properly focusing incoming light rays onto the surface of the retina. Consequently, individuals with cataracts experience a significant reduction in visual clarity, leading to blurred vision and potentially impacting their daily activities

Cataracts can significantly impact a person's quality of life, making it challenging to perform routine tasks such as reading, driving, or recognizing faces. Fortunately, cataract surgery is a highly effective and commonly performed procedure that involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL), restoring clear vision and improving overall visual function..

Types of Cataract?

Nuclear Cataracts: form in the middle of the lens and cause the nucleus, or the centre, to become yellow or brown.

Cortical Cataracts: are wedge-shaped and form around the edges of the nucleus.

Posterior Capsular Cataracts: form faster than the other two types and affect the back of the lens.

Congenital Cataracts: present at birth or form during a baby’s first year, are less common than age-related cataracts.

Secondary Cataracts: ataracts caused by disease or medications. Diseases include glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.

Traumatic Cataracts develop after an injury to the eye, but it can take several years for this to happen.

Radiation Cataracts: can form after a person undergoes radiation treatment for cancer.

How Do You Know If You have Cataract?

If you have the above Symptoms, Our doctors & Optometrists will perform a comprehensive eye checkup to assess presence of cataract and stage.

A Detailed History Recording

Visual acuity: using eye charts to measure near and distance vision.

Dilated Eye Examination: Via instilling eye drops to dilate the pupil.

Slit Lamp Examination: To assess the grade of cataract

When Does Your Cataract Require Surgery?

If visual difficulties from cataracts begin to interfere with your daily routine and work, it may be necessary to seek treatment. Depending on the severity of the cataract, your eye doctor may recommend surgery as a viable option. In cases where the cataract is hypermature or causing increased eye pressure or lens swelling, emergency surgery might be required to alleviate the condition. Prompt intervention can help restore clear vision and alleviate discomfort in such situations.

What type of anaesthesia is Required for Cataract Surgery?

Local Anaesthesia:
Commonly used.

Topical Anaesthesia::
in cases of Phacoemulsification.

General Anaesthesia:
In children/mentally challenged patients.

What Are The Different Cataract Surgical Treatment options?

Fast healing post-surgery

The surgeon decides which is a safe surgery for a particular patient

Types Of Intraocular Lenses (IOL)

Monofocal IOLs: The most common type of IOLs used is called a monofocal IOL. It is set to focus for clear distance vision. For near work you need to wear spectacles that is for reading or close work.

Multifocal IOLs: These IOL’s can focus both for distant and near vision as there are different focusing powers within the same lens. Therefore you are less dependent on glasses. Most tasks can be performed without glasses.

Toric IOLs: Astigmatism is a refractive error caused by an uneven curve in your cornea.Astigmatism if not corrected can cause blurry vision for distance or near without glasses. The toric lens is designed to correct that refractive error.

Accomodative IOLs: These lenses move or change shape inside your eye, allowing focusing at different distances.
