Cataract is clouding of the eye’s natural lens. It is a natural process of ageing. Every individual gets it sooner or later. Cataract impairs focusing of light on the retina and hence blurs vision.
What Are The Causes Of Cataract ?
Old age is the most common cause of cataract. It also sometimes occurs relatively early in life due to factors such as injury, excessive sunlight, toxic chemicals, changes in the body’s metabolism, drugs, or other eye diseases, such as glaucoma and inflammation. There can also be a hereditary predisposition to an earlier occurrence of cataracts…
What Are The Type Of Cataract ?
Senile Cataract (Due to old age)
Congenital Cataract (occurs by birth)
Traumatic Cataract (Due to eye injuries)
Steroid Induced Cataract (side effects of the drug)
What Are The Symptoms Of Cataract ?
People with cataract, even when wearing glasses, typically have:
Glare at night
Difficulty in recognising colors
Foggy / smoky vision
Frequent changes in their glass prescription
What Is The Treatment For Cataract ?
There are no medicines with proven efficacy to prevent or to treat cataract. The only effective treatment is the surgical removal of cataract. Diabetes, hypertension, and other general health problems are not a contraindication for cataract surgery. The cataract need not ‘mature’ for surgery.
When Is Treatment Advised?
The decision to treat a cataract is made together by the eye care practitioner and the patient. It is based on the degree to which the cataract is impairing vision and the effect of the impairment on the patient’s quality of life.
There Are 3 Treatment Options Available For
Cataract:
I. ECCE (conventional method) II. Phaco Emulsification Ill. Micro Incision Phaco Emulsification with Foldable Intraocular Lens Implantation
I. ECCE (Conventional Method)
Requires an incision of 9 mm
The surgeon removes the clouded lens in one piece
A hard rigid lens is implanted
Multiple stitches are required
Increased risk of post-operative distorted vision and complications
Most patients require glasses for both distance and near vision
ll. Phaco Emulsification
The clouded cataractous lens is extracted by fragmenting it into tiny pieces with ultrasound energy and aspirated out with a suction device. The cataract is removed through a small self-sealing wound. There are no sutures applied on the eye. The patient will need glasses for near vision.
Advantages:
Requires no stitches (Incision 2.8 mm)
Is non-invasive and painless
Shorter overall duration of surgery
Less post-operative discomfort
Minimum post operative restrictions
Early rehabilitation
Less induced astigmatism
Perfect early restoration of vision
Ill. Micro Incision Phaco Emulsification With Foldable Intraocular Lens Implantation
Cataract extraction by Phaco Emulsification through a 1.8 mm incision and implanting a Foldable Intraocular Lens is a definite technological advancement from conventional surgery. The lens is injected into the eye through a small incision and it opens up within the eye like a flower.
Advantages:
Wound healing is very fast
Wound stability is far better since the entire surgery is done through a very small opening
Induced astigmatism is minimal
Decreases glare because of the superior surface quality of the lens
The patient will not feel any surgical impact and has a painless and suture-less surgical procedure making this an outpatient procedure
