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..

What Are The Risk Factors?

Symptoms of Cataract?

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.

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.




Frequently Asked Questions (F.A.Q.)

  • What are the pre-operative assessment and procedures prior to cataract surgery?
    • Before undergoing cataract surgery, the patient goes through a comprehensive evaluation process utilizing advanced technologies. The ZEISS IOL Master 700 is employed to assess the patient's ocular measurements accurately. Additionally, corneal endothelial cell count is performed to evaluate the health of the cornea. Retinal function tests, including OCT scanning, are conducted to assess the condition of the retina. If the patient has other associated eye diseases such as glaucoma, diabetic retinopathy, macular diseases, or neurophthalmic conditions, relevant tests are performed to ensure appropriate management. Evaluation for dry eye disease is also conducted to address any ocular surface issues.
      In addition to ocular assessments, systemic parameters such as blood pressure, blood sugar levels, ECG, and other relevant blood and urine tests are performed to ensure the patient's overall health compatibility for the surgery. Certain mandatory blood tests, including HbAsG, HCV, and HIV, are conducted for the safety of the staff, surgeon, and other patients. A thorough health assessment by a physician, cardiologist, nephrologist, pulmonologist, neurologist, or other specialists may be required, and a fitness letter from the respective specialist is obtained accordingly.
      Considering the current COVID-19 pandemic, COVID-19 testing is conducted prior to surgery following government guidelines. Finally, the patient is required to provide consent for the surgery, anesthesia, and acknowledge the potential risks associated with the procedure. The consent also covers the possibility of guarded visual prognosis and highlights any high-risk factors. A responsible relative is also involved in the consent process to ensure transparency and understanding of the surgical procedure.
  • How do I Prepare for The Surgery?
    • Instill eye drops as per instructions and take your regular medications for other diseases if any as prescribed by the physician Take a bath and wear fresh clothes and a fresh mask Have a light breakfast.
