Once we know what a cataract is, let’s have a look at the Management Of Cataract
First and foremeost, there are no medicines which help resolve a cataract. Our prime responsibility is to spread awareness of this basic fact and protect gullible patients from Quackery and downright dangerous methods claimed to ‘cure’ the cataract.
Surgery performed by a trained Ophthalmologist in a sterile Operation Theatre is the Only safe, approved way to resolve a Cataract
No matter what you do, no matter how hard you try, a scratched windshield needs to be replaced. This is exactly what we do in a Cataract Surgery. We REMOVE the aged/damaged lens; and REPLACE it with an artificial one.
The major strides in the evolution of Cataract Surgery have been first in the Method of Removal, and subsequently in the Implanted Artificial Lens.
Coaching technique described
in Sushrutha Samhita.
The first interventions for lens of the eye date back to 2000 B.C. in Egyptian empire and Indian Sciences. Back then, the procedure was limited to merely displacing the lens from its position within the eye itself – without any surgery – COUCHING. This would bring about a mild improvement in vision. The techniques used were understandably barbaric and rudimentary.
Then came a back and forth change as to whether to remove the lens with (intracapsular) or without (extracapsular) the entire Capsule.
The French ophthalmologist Jacques Daviel (1696–1762) was the first modern European physician to successfully extract cataracts from the eye. He performed the first EXTRACAPSULAR CATARACT EXTRACTION on April 8, 1747.
Albrech von Graefe (1828-1870), a tremendously important Ophthalmologist, died at the early age of 42. He gave a dissertation on 'modified linear extraction' among other significant papers at the 3rd International Congress of Ophthalmology, Paris. Ophthalmology developed tremendously through the application of the ophthalmoscope by von Graefe.
At the turn of the Century, a medical student told Sir Nicholas Ridley, that it was a pity that the cloudy lens extracted could not be replaced with a clear one. At that time, Sir Nicholas was a surgeon at Moorfield Eye Hospital and St Thomas' Hospital in London, specialising in Ophthalmology. Dissatisfied with the poor acuity and loss of binocular single vision following cataract extraction and the poor outcome, with the contact lenses then available, he had early in his career envisaged using an artificial lenticulus. He went on to pioneer ARTIFICIAL INTRAOCULAR LENS TRANSPLANTSURGERY for cataract patients.
In 1967, American Charles D. Kelman (1930-2004), an ophthalmologist pioneer in cataract surgery, introduced PHACOEMULSIFICATION after being inspired by his dentist's ultrasonic probe. This technique use ultrasonic waves to emulsifythe lens in order to remove the cataracts without a large incision. This new method of surgery decreased the need for an extended hospital stay and made the surgery less painful. The principle behind this has now been taken to cutting edge technology.
With the development in IOLs, the method of access to the catracted lens, removing it and Implanting the IOL developed further.
MICROSURGERY MADE COUCHING AND ICCE OBSOLETE
Most cataract extractions are now ExtraCapsular i.e. Surgeons leave the Posterior Capsule behind as a base for the artificial Intra Ocular Lens.
MICROSURGERY involves Extracpasular Lens Extraction and IOL Implantation.
Thanks to recent advances, the Size of Incision required is down from 6-10 mm to 2mm i.e. From an incision that went halfway round the eye, to barely the tip of a pen.
Microscopic surgery and Flodable lenses enabled the entire procedure to be accomplished through these tiny ports.
The IOL – to be discussed in subsequent blog post.
Majority of the cataract surgeries under VisionFoundation of India are performed via Phacoemulsification.
The Lens implanted is the Indian foldable lens.
So now that you know about Phaco, you can reassure prospective patient that :
- · It is Bladeless – a very tiny incision is all that’s needed
- · There are No Stitches – since the incision is small, it self-heals
- · Post op care is simple and in a vast majority, uncomplicated
- · A clear lens is implanted to restore optimum vision
So, what can you do now?
