What is Cataract Surgery?

The lens is located behind the iris, the colored part of the eye. It is made of water and protein and helps focus light into the retina through which visual signals are sent to the brain. Excess of protein build up leads clouding of the lens and is called Cataract. It reduces vision due to blockage of light passing to the retina. Based on the size and location of the opaque/cloudy area the vision is impacted negatively. Vision through the cloudy lens is like seeing through a frosty window. The condition is generally seen in older age group however it can also develop at a younger age and there have been many cases to support this fact.

Who can get a cataract Surgery?

Most cataracts develop with advancing age. As a person ages, the lens in the eyes becomes less flexible, less transparent and thicker. Most of the cataracts that occur due to aging are witnessed in the 50-60 age group. Early cataracts Surgeries are also becoming more common off-late.

Listen to Dr. Himanshu Mehta speak about cataract Surgery and how technology at The Vission Eye Center can bring about complete, swift restoration of vision.

Symptoms of Cataract

  • Blurred Vision -  Cataract Symptom Blurred Vision
  • Photophobia, Glare - Cataract Symptom Photophobia, Glare
    (sensitivity to light)
  • Difficulty in Driving at night  - Cataract Symptom Difficulty in
    Driving at night
  • Double vision Cataract Symptom Double vision
  • Colours may appear faded -  Cataract Symptom Colours may
    appear faded
  • Second Sight - Cataract Symptom Second sight (patients start seeing
    near vision clearly which
    they couldn’t see earlier)
  • Frequent changes in glasses power - Cataract Symptom Frequent changes
    in glasses power

Major Causes of Cataract

Other Risk Factors to be avoided
  • Smoking
  • Diabetes
  • Prolonged exposure to sunlight
  • Excessive alcohol usage
Treatment for Cataract Surgery in Mumbai

Currently, there is no preventive treatment for cataract neither there is any medication, eye drops, exercises or glasses to cure the same. The only way to get rid of cataract is Surgery. Cataract surgery is one of the most safest and common type of surgery. Cataract surgery is performed to remove the cloudy lens from the eye. Permanent intraocular lens implant (IOL) selected based on the patient's specific eye measurements replaces the damaged lens and provide the required focusing power.

At The Vission Eye Center there are two types of surgery procedures performed,

  • Phacoemulsification is a modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic hand piece and aspirated from the eye and an intraocular lens (IOL) is put in its place.
  • Femtosecond assisted cataract surgery – Lensx laser FDA Approved( Bladefree Cataract surgery )-in this procedure femtosecond laser is used for making incisions without blades, fragmentation of lens and capsulotomy.

Diferent types of IOL
Monofocal IOLs

Monofocal IOL is the most widely used lens. It has one focusing distance. It is set to either focus on up close, medium range or distant vision. Most people have them set for clear distant vision and wear eyeglasses for reading or other close viewing activities. An aspheric monofocal IOL may be ideal for many patients, which is a wavefront-designed, modified-prolate, anterior-surface optic, has a fixed amount of negative spherical aberration that compensates for the positive spherical aberration of the average human cornea.

Multifocal IOLs

The technology of the multifocal intraocular lenses (IOLs) is advancing as the objectives of the cataract surgery are becoming more embracing. Nowadays, patients have higher expectations from the surgery and more often desire spectacle-free life post the cataract surgery.

Extended depth of focus IOLs

Extended Depth of Focus (EDOF or EDF), or Extended Range of Vision, is a new technology that has recently emerged in the treatment of Presbyopia-correcting IOLs. In contrast to multifocal intraocular lenses (IOLs) used in treatment of presbyopia, EDOF lenses work by creating a single elongated focal point to enhance “range of vision” or “depth of focus”. Both multifocal and EDOF lenses have resulted in increased levels of spectacle independence, the EDOF IOL has performed at par with monofocal and multifocal IOLs with regards to distance visual acuity results, with a trend toward superior uncorrected intermediate visual acuity, while multifocal IOLs have trended toward having superior uncorrected near visual acuity results.

Why Dr. Himanshu Mehta for cataract Surgery?

Vission Eye Center is a state-of-the-art facility with a team of highly trained surgeons who have extensive experience and deploy most up-to-date technology and techniques. With a patient friendly atmosphere, you can be rest assured that you are in safe hands.

Blade Free Cataract Surgery Lensx USFDA Approved

The LenSx Femtosecond laser utilizes a beam of laser light to create the necessary incisions for cataract surgery. An advanced computer-guidance system, controlled by one of our experienced surgeons, directs the laser over the eye to provide the most precise and accurate results for each individual patient. This makes it possible for the successful combination of the surgeon’s skills with state-of-the-art technology to produce extraordinary results. Incisions, Rexhis opening or capsulotomy, Fragmentation of the lens and Limbal Relaxing incisions for astigmatism correction are all done in just 40 seconds!

Advantages of Blade free cataract surgery

  • Higher precision and consistency
  • Less tissue damage as no blades are used
  • Custom-guided laser designed to perform the procedure according to the unique characteristics of your eyes
  • Automates traditionally challenging steps of cataract surgery

Laser Cataract Surgery in Mumbai

In laser cataract surgery, the surgeon creates a precise surgical plan for the corneal incision with a sophisticated 3-D image of the eye called an OCT (optical coherence tomography). The goal is to create an incision with a specific location, depth and length in all planes, and with the OCT image and a femtosecond laser, it can be replicated with highest precision each time without the variable of surgeon experience.

In laser cataract surgery, the anterior capsulotomy is performed with a femtosecond laser. Studies have shown that capsulotomies performed with a laser have greater accuracy and reproducibility.

The laser, on the other hand, softens the cataract as it breaks it up. By breaking up the cataract into smaller, softer pieces, less energy is required to remove the cataract.

Astigmatism usually is caused by the cornea being more curved in one meridian than others. To reduce astigmatism, small incisions can be placed in the periphery of this more curved meridian; as the incisions heal, this meridian flattens slightly to give the cornea a rounder, more symmetrical shape.

During refractive laser-assisted cataract surgery, the OCT image can be used to plan laser LRI or AK incisions in a very precise location, length and depth. This increases the accuracy of the astigmatism-reducing procedure and increasing the probability of good vision without glasses post cataract surgery.
