Common signs and symptoms of a cataract
Blurry or cloudy vision
Glare- sunlight, bulbs, headlights
Seeing halos around lights
Poor night vision
Colours appearing less vibrant
How is a Cataract diagnosed?
Cataracts can only be diagnosed through a comprehensive eye examination.
Your eye doctor will utilize diagnostic tools to measure the following:
Visual acuity to determine to the extent at which a cataract may be limiting clear vision at all distances.
Refraction will determine if your vision has changed— necessitating a new optical prescription for eyeglasses or contact lenses.
Evaluation of the lens using high magnification and illumination to identify the location and extent ofcataracts.
Evaluation of the retina of the eye through pupil dilation.
How are cataracts treated?
There is no medicine or exercise to stop or reverse cataract.
The only treatment is its surgical removal. If the vision is blurred slightly then change in spectacle power may help.
But if one has difficulty in activities like driving, reading, watching TV or identifying faces of people cataract surgery is the only solution.
Can a Cataract come back after surgery?
• It is not possible for a cataract to “grow back” because the lens where the cataract forms have been removed and replaced.
• The intraocular lens (IOL) implant never needs maintenance or replacement.
• In some patients, a cloudy film can form behind the implant on the lens capsule membrane, usually a few months after the original cataract surgery.
• This condition is called posterior capsular opacification, or secondary cataract (because it seems as if the cataract has returned).
• The surgeon can safely and quickly restore vision by creating opening in the capsule with a specialized laser. It is a simple outpatient procedure.
What can I expect immediately after cataract surgery?
This is a walk-in, walk-out procedure.
The total procedure takes approx. 2 hours.
The patient is discharged approx. 15 minutes after surgery.
One of our clinic assistant staff will brief you about instructions and all post operative care at the time of discharge.
Generally, there is little discomfort or mild pain following surgery. Visual recovery may take few days.
What could be expected within the first several days of cataract surgery?
• Considerable improvement in vision.
• Ability to resume normal activities most of them from day 1.
• Gradual and steady decrease in the mild eye discomfort.
• Minor discomfort is normal on the first day
• Mild light sensitivity would wane off.
Types of Lens
MonofocalLens:
This type of lens has a single ‘power’. It has capability to focus rays coming from either distant or near objects on the retina. Normally, the doctor implants a lens that can focus clearly on distant objects. This requires the patient to use specs for near activities like reading, sewing, using cell-phone and laptop.
MultifocalLens:
Multifocal lens has multiple focal power that enables it to focus on objects at various distances. It gives clear distant and near vision to a person. This does away with the requirement for specs.
ToricLens:
This kind of lens is implanted in people having cataract with Astigmatism (cylindrical number). Toric lens has cylindrical power in addition to the spherical power which enables clear vision without specs.
EDOF Lens:
This kind of lens provide a continues range of clean vision from a distance to an intermediate range, reducing the need for reading glasses for tasks like using a desktop.
