Cataract is the clouding of the eye’s natural lens. When the lens is not clear due to a cataract, no clear image can be formed on the retina resulting in poor vision. It is the most common cause of vision loss in people over age 40 and is also the foremost cause of blindness in India as well as the world. Dr. Shroff’s Charity Eye Hospital has been a pioneer in the field of cataract surgery offering cutting edge technology and a high standard of care to a large population.
What Causes Cataract?
The major risk factor for cataract is increasing age. The other risk factors which may enhance the development of cataract are
Professions involving prolonged exposure to sunlight
Certain diseases, like diabetes
Personal behaviours, like smoking
What are the symptoms of cataract?
Cataract causes a painless and gradual decline in the vision. The patients usually complain of difficulty in seeing things at a distance or problems in reading in low light or glare and difficulty during driving
What are the tests before undergoing a cataract surgery?
Dr. Shroff’s Charity Eye Hospital is equipped with the latest world class instruments used in the diagnosis and evaluation of a cataract patient as well as calculation of the IOL power to be implanted. These include
Dilated eye examination– the pupils of the eye are dilated with drops to examine the cataract on a slit lamp and the retina and optic nerve on an indirect ophthalmoscope. The effect of the dilating drops lasts for 2-3 of hours, during which time the patient may experience blurred vision
Optical Biometry – We us the state of the art Zeiss IOL Master 700 for the measurements of the eye to determine the most accurate possible power of the lens to be implanted during cataract surgery
OCT – The Zeis Cirrus OCT is used for scanning the retina to check for any retinal disease before undergoing cataract surgery
B Scan Ultrasound – This is used to scan the retina in cases of advanced cataracts
Specular Microscopy – The Rodenstcok REM 3000 specular microscope helps in diagnosing any corneal disease
Pentacam – The Oculus Pentacam helps in scanning the cornea for any irregularities in case of previous history of LASIK/PRK/RK
What is the treatment for cataract?
The treatment of cataract is primary surgical. One may be able to improve the vision for a while using new glasses, strong bifocals, appropriate lighting or other visual aids. But it is prudent to perform a cataract surgery once it starts interfering with ones daily activities.
Cataract surgery is a fairly simple, day-care procedure. It is relatively painless and results in fast visual recovery. During surgery, the surgeon will remove your clouded lens and in most cases replace it with a clear, plastic (synthetic) intraocular lens (IOL).
How is the cataract surgery done?
We at Dr. Shroff’s Charity Eye Hospital have a team of the best skilled and highly experienced doctors to take care of our cataract surgery. Cataract surgery is an extremely skilled surgery and our doctors have managed thousands of such cases making them one of the best in the country.
We also have the latest machines which make the surgery much safer and extremely perfect. This includes the Alcon Centurion Vision System with Active Fluidics and the Alcon Infinity system, which are currently the best machines for operating a cataract. These enable micro incision cataract surgery leading to fast healing, order antibiotics vision and minimal post operative restrictions
The steps of micro incision cataract surgery include
A very small 2 mm incision is made in the eye
The cataract is broken into pieces and emulsified
A foldable lens is implanted into the eye
In most cases no stitch is needed making it absolutely painless and bloodless
The patient can leave for home within an hour
It can also be done under topical anesthesia (i.e. without injection)
The Zepto Advantage
Zepto is the most recent, state of the art technology which helps in making the most perfect capsulorrhexis (opening in the anterior capsule) making it possible to do a safe and accurate surgery in even the most difficult cases. It gives a robotic precision and predictable results everytime for every patient.
What are the type of Intra ocular Lens (IOL) offered?
We have the widest and the best possible options of IOL available for use during cataract surgery. The patient can choose his/her IOL based on the requirements and affordability in consultation with our doctors and counsellors. The types of IOL include
Monofocal IOL– These are the most common type of lenses implanted. They help in providing excellent distance vision, but for near work the patient would need reading glasses. There are further qualities available within these lenses which the patient can choose according to the needs. The premium aberration free aspheric IOL’s provide the best quality of vision and contrast.
Toric IOL– These lenses are recommended for patients having astigmatism or cylindrical power in their cornea before cataract surgery. These lenses would reduce the dependence on glasses for distance vision post surgery. The patient would still need glasses for near work. Our doctor would help you in advising whether your eyes need a Toric IOL.
Mutifocal IOL– These are lenses which have different segments which help in focussing light form distance as well as near without the need for glasses. The lens would give good vision for most day-to-day activities without glasses. However, one may need occasional glasses for reading fine prints close by or at a distance. Some patients experience glare and haloes at night time.
Extended Depth of Focus IOL & Trifocal IOL – These lens provide good distance, intermediate and near vision with reduced chances of glares and haloes making them good for driving as well as computer work.
