Cataract Treatment Then and Now: How advanced cataract treatment has got an edge over the traditional one
Cataracts are one of the most common eyesight problems. Also known as 'Motiyabind' in Hindi, cataracts are a disorder in which clouding of the natural lens of the eyes occurs. If not treated in time, the clouding starts becoming opaque and disrupts vision.
The retina in our eyes is responsible for receiving light, converts it into neural signals, and sends it to the brain via the optic nerve for visual recognition. When the lens is not clear due to a cataract, no clear image can be formed on the retina resulting in poor vision.
Causes of cataracts
Ageing is considered as one of the most common reasons for the development of cataracts. It causes difficulty in doing daily activities like reading, writing, driving, etc.
There are many other reasons as well for the development of cataracts, like:
- Exposure to ultraviolet (UV) rays
- Prolonged usage of steroids and other prescription drugs
- Eye injury that can cause cataracts or result in loss of vision
There are several other factors that increase the risk of cataracts in an individual, like:
- Poor nutrition
- Excessive consumption of alcohol
- Cataracts already running in the family
- Radiation therapies
Cataract treatment then and now
Cataract treatment is one of the oldest known surgical procedures in medical history. In the absence of advanced medical technologies, treating cataracts earlier used to be very different from what we witness today. Advanced cataract treatment has made this surgery uncomplicated and fast.
Traditional cataract surgery
Traditional cataract surgery used to take place via techniques like 'couching.' 'Couching' dates back to 5th century BC that involved the use of a sharp object, like a needle to dislodge the cataractous lens from the visual axis of the patient.
With the arrival of modern techniques gradually over time, cataract treatment was made more relaxed and safe. In another form of traditional cataract treatment, eye specialists made an incision in the patient's eye using a precise blade.
In this procedure, surgeons put an ultrasonic probe in the eyes to break up cataracts. The pieces of cataracts are removed through suction. After that, a new, artificial lens is placed into the eyes through the same incision.
Since this surgery involves using a scalpel to make an incision effectively, it has to be performed by a skilled and experienced surgeon.
Cataract advanced treatment (Femto laser-assisted cataract surgery)
Advanced cataract treatment involves the use of laser technology. It is an automated procedure that dramatically reduces time and energy in contrast to manual surgery. Laser-assisted surgery helps surgeons to understand the exact depth, location, and size of the incision. The imaging device used in laser surgery for cataracts helps map the lens's surface and eyes.
Femto laser-assisted cataract surgery is the world’s leading laser-automated technology for cataract surgery.
Robotic laser cataract surgery benefits:
- Blade free, laser-assisted procedure
- The actual working of the laser takes less than 1 minute
- Capsular opening, fragmentation of cataract with laser & corneal incisions are fully automated to deliver precise cuts and is more accurate than manual blade incision
- Reduces phaco energy
- Enables Astigmatism correction at the time of cataract surgery
- Greater safety, precision & accuracy
- A better visual outcome with quicker recovery
Choosing an intraocular lens (IOL)
Before you go for cataract surgery, the eye specialist will do a comprehensive eye checkup to assess your eyes' overall condition. You might need to go for a refraction test so that the amount of nearsightedness, farsightedness, and astigmatism can also be assessed.
Some other tests might involve biometry, or intraocular lens (IOL) tests to check the IOL power needed in your eyes. You could also undergo a specular microscopy test to examine for any corneal disease, corneal curvature, etc., amongst many.
