PHACOEMULSIFICATION -- The No Stitch Cataract Surgery
WHAT IS A CATARACT ?
The human crystalline lens which is clear and transparent is the primary focusing mechanism of the eye. With age, the
lens becomes cloudy and opaque, thereby hampering a clear vision. Any opacity in the crystalline lens is called cataract or "Safed Motia".
WHAT CAUSES CATARACT?
Ageing is the commonest cause. With age, the lens proteins get altered and opacify. Other causes of cataract include :
congenital developmental anomalies, trauma, inflammation of the eye, certain metabolic diseases etc.In the absence of any drugs which remove or slow the process of cataract formation, surgery remains the only cure.
WHEN TO GET CATARACT SURGERY DONE?
Cataract should be removed when it decreases vision that begins to affect your daily activities. When glare or bluer interfere while you are driving, or you have to give up your favourite hobby, it is time to consider having surgery. DO
NOT WAIT FOR THE CATARACT TO GET MATURE for this may lead to complications and a more difficult surgery.
Get the surgery done, when you feel any incapacitation towards performing your normal duties. CATARACT SURGERY CAN BE PERFORMED IN ANY SEASON.
PHACOEMULSIFICATION
The most modern method of removing a cataract is through the use of Phacoemulsification procedure. The Phacoemulsifier is an ultrasonic probe which is vibrating at the frequency of sound, i.e. 40 KHz. This helps in fragmenting and emulsifying the cataract into microscopic pieces, which are simultaneously and gently aspirated out of the eye. This method of cataract removal, is considered the least traumatic to the patient's eye.
SMALL INCISION
A self sealing tunneled incision is made in the cornea and/or sclera, one to three millimeter above the iris. Through this
tiny 3mm incision, the cataractous lens is removed by Phacoemulsification and a foldable intraocular lens is implanted. Due to the small incision and its architecture, the surrounding tissues overlap to make the incision self sealing. In routine cataract surgery, the eye has to be opened to 10-12 mm, to allow the nucleus of the lens to be delivered as a single piece.
FOLDABLE INTRAOCULAR LENS (IOL)
When the opaque, clouded lens of the eye is removed during cataract surgery, a replacement for the human lens is needed to restore focus to the eye. Earlier this was done by wearing thick spectacles or contact lenses postoperatively. An artificial Intra-Ocular Lens (IOL) is implanted into the eye at exactly the same position, from where the cataract has been removed. Foldable intraocular lenses have revolutionized cataract surgery because they can be folded and injected into the eye through this self sealing 2.5mm tunnel incision. Once inside the eye, they unfold to their regular optic size of 6 mm. Foldable lenses are made from a fully cured solid form of acrylic that is completely inert in the eye. Conventional Intra Ocular Lenses (IOLs) are made of polymethyl methacrylate,(PMMA) a plastic which cannot be folded. Thus the incision ie required to be enlarged to 7 mm for their insertion, thereby negating part of the advantage, gained by having a small incision in Phacoemulsification. HOW IS THE LENS INSERTED INTO THE EYE? The foldable lens is folded using a specially designed folder and holder. Alternatively, a specially designed injector, much like a syringe is used to implant the lens. The folded lens held with the specially designed holder/injector, is
inserted through the small tunnel incision, over the iris into the centre of the pupil. There the lens is slowly released,
where it unfolds into the same capsular bag which once housed the natural lens of the eye, restoring focus after cataract surgery.
WHAT ARE THE ADVANTAGES OF PHACOEMULSIFICATION WITH FOLDABLE IOL?
Advantages
1) Early visual rehabilitation for the patient.
2) It allows a stitchless surgery.
4) Final glasses can be given in two weeks as compared
to ten weeks after the conventional surgery.
5) Post-operatively, the wound is very secure.
6) Early mobility of the patient is ensured.
In keeping with our commitment to provide world class eye care services, we at our centers we have acquired the advanced Soverign Phacoemulsification unit from USA. |
