Cataract
Restoring Clarity for a Brighter Vision
What is Cataract?
A cataract is a common eye condition where the natural lens of the eye becomes cloudy, leading to blurred or unclear vision. It usually develops gradually with age and may affect daily activities like reading, driving, or recognizing faces if left untreated.
Symptoms That May Indicate Cataract?
Cloudy Vision
Blurred or cloudy vision is one of the most common signs of cataract, making objects appear hazy, dull, or unclear over time.
Difficulty seeing at night
Difficulty seeing at night is a common cataract symptom that may cause poor vision in dim light, especially while driving or walking at night.
Sensitivity To Light
Increased sensitivity to light may cause discomfort, glare, or difficulty seeing clearly in bright sunlight or while facing headlights at night.
Dull Color Vision
Dull or faded color vision may make colors appear less bright and less vibrant due to the clouding of the eye’s natural lens.
Frequent Glasses Changes
Frequent changes in glasses power may sometimes indicate progressing cataract affecting vision clarity over time.
Main Causes of Cataract
Main Causes of Cataract?
- Age-Related Cataracts
- Congenital Cataracts
- Secondary Cataracts
Investigations
- Complete eye examination
- IOL Power Calculations
Intraocular lens (IOL) power calculation is a crucial step in cataract surgery, ensuring that the implanted lens provides optimal vision correction for each individual patient.

Sac Syringing
Sac syringing test, also known as lacrimal irrigation or naso-lacrimal duct irrigation, is a diagnostic procedure used to evaluate the patency and function of the tear drainage system. During the test, a small amount of saline solution is gently flushed through the tear ducts to assess whether tears drain properly from the eye into the nasal cavity. This is important because any underlying blockages or abnormalities in the tear drainage system can increase the risk of postoperative complications, such as excessive tearing or infection.
Blood Investigations include
Intraocular Lenses (IOLs)
Intraocular lenses (IOLs) are artificial lenses implanted in the eye to replace the natural lens that is removed during cataract surgery. These lenses are necessary to restore clear vision and focus light onto the retina, allowing for improved visual acuity. Without an IOL, the patient would likely require thick eyeglasses or contact lenses to achieve functional vision
Types of IOL Materials
- Rigid PMMA (Polymethyl Methacrylate)
- Hydrophilic Foldable IOLs
- Hydrophobic Foldable IOLs

What is a Toric Intraocular Lens (IOL)?
A toric intraocular lens (IOL) is a specialized type of artificial lens implanted during cataract surgery or refractive lens exchange to correct astigmatism. Astigmatism is a common refractive error caused by irregular curvature of the cornea or lens, resulting in blurred or distorted vision at all distances.
Advantages of Toric Intraocular Lenses IOL
- Improved Vision Quality
- Reduced Dependence on Glasses
- Enhanced Visual Outcomes
Types of Cataract Surgery
Small Incision Cataract Surgery (SICS)
Small Incision Cataract Surgery (SICS) is a technique used to remove cataracts and implant intraocular lenses (IOLs) through a smaller incision compared to traditional extracapsular cataract extraction (ECCE).
At Shriram Eye Hospital, we specialise in SICS with Dr. Anil Shah’s Snare technique, a refined approach that involves making a tiny 3.5 mm incision. This technique is performed topically and suture less, allowing for rapid recovery and the implantation of advanced lenses. Dr. Arpit Shah, our expert ophthalmologist, will assess your suitability for SICS and determine the best approach to ensure optimal outcomes and safety.
Advantages of SICS with Dr. Anil Shah's Snare Technique over conventional SICS
Minimally Invasive
The small incision size minimises trauma to the eye and surrounding tissues, resulting in faster healing and enhanced patient comfort.
Advanced Lens Options
SICS with Dr. Anil Shah’s Snare technique allows for the implantation of advanced lenses, including multifocal and toric lenses, to address various visual needs.
Close to Phaco Incision
The 3.5 mm incision used in Dr. Anil Shah’s Snare technique is similar in size to the incision used in phacoemulsification (Phaco) surgery, offering comparable results with reduced surgical invasiveness.
Surgical Treatment - Micro-Incision Cataract Surgery (MICS)
At Shriram Super Speciality Eye Hospital, we utilise the most advanced surgical techniques and equipment to perform cataract surgery. Our surgical approach, known as Micro-Incision Cataract Surgery (MICS), involves the following steps
