What is cataract?
Cataract is clouding of the natural lens, which initially leads to blurring of vision and later to blindness.
How is cataract treated?
Cataract is removed surgically and an artificial lens called intraocular lens (IOL) is immediately placed at the same place.
Will I have to wear glasses if I get intraocular lenses implanted when I get my cataract operated?
Earlier, before intraocular lenses were available, people ended up with a +10 glass for distance and a +13 glass for reading. These days with intraocular lenses the power required is nominal and the debilitating distortions of the very high numbers is a thing of the past. The newer multifocal intraocular lenses have further reduced the dependence on glasses to almost zero. The accuracy of the newer instruments like IOL Master from Zeiss (Germany) and Verion from Alcon (a division of Novartis) to measure and calculate the intraocular lens power to be implanted has further brought down the number of glasses required after cataract surgery.
What are the newer types of intraocular lenses available?
Aberration free lenses give a distortion free image. For people with cylindrical numbers, toric lenses reduce the cylindrical number Multifocal lenses have multiple rings which focus at different distances thus reducing the need for glasses for near, distance and intermediate distances. Multifocal lenses reduce the dependence on glasses. The latest lenses available now are a combination of toric and multifocal lenses for people who have cylindrical numbers and do not wish to wear glasses.
What is phacoemulsification?
The conventional technique for cataract removal is called phacoemulsification. This technique uses a machine to break up the lens by ultrasound energy and wash out the pieces through a very small incision. We have two very sophisticated phacoemulsification machines called Centurion and Infinity to do just that. The Intraocular lens is folded and injected into the eye through the small incision. It unfolds once it is in the eye. The extremely small (2.2 mm) incision allows the surgery to be completed without sutures and the recovery is extremely fast.
What is the latest technique available worldwide to remove cataract?
The latest and the very best, almost futuristic technology available today is LASER ASSISTED CATARACT SURGERY. This technology uses a laser to break up the cataract, make openings in the cataract and to make the incisions even before taking the patient into the phacoemulsification operation. We use a machine called LenSx from Alcon (division of Novartis).
The cornea is the transparent window in front of the eye. Expert, specialized and timely treatment is of paramount importance in saving eyes suffering from many corneal diseases. Many diseases of the cornea, which were incurable, are now being successfully treated. Keratoconus is weakening of the cornea leading to its protrusion or ectasia. A new technique called corneal collagen cross linking is used to stiffen the cornea is available with us. This process has revolutionized the treatment of keratoconus and has saved many eyes from going blind.
The two eyes are normally parallel except while looking at near objects. Squint is when the eyes are not parallel. Apart from its cosmetic problems, it can give rise to a lazy eye or loss of stereoscopic vision. To preserve the stereoscopic vision and to prevent lazy eye, it is important to treat squint as soon as possible, as the development of the eye takes place in the early years of childhood. The treatment includes glasses, exercises, surgery or a combination of these. All facilities for the diagnosis and treatment are available at our hospital.
The retina is the layer at the back of the eye, which is like the photographic film in a camera. Major advances in technology and technique have changed how retinal diseases are diagnosed and treated. The constellation machine from Alcon is the best vitrectomy machine in the world today, giving us the option of small incision stitchlessvitreoretinal surgery at our clinic.
