What is Cataract Surgery?
Cataract surgery is a common type of eye surgery used to remove cataracts. When light enters the eye, it acts like a camera and focuses on it. As light passes through, this lens is normally clear. However, if this lens becomes cloudy and hardens, they are now referred to as “cataracts.” Cataracts prevent light from entering our eyes, resulting in blurred vision and the appearance of ‘halos’ when we stare at lights. As a result, Cataract Surgery removes the lens and replaces it with a new artificial lens, restoring vision to normal.
Treatment for Cataract
Cataract is an eye condition that cannot be treated with medications. Surgery is the only way to remove a cataract. It is one of the most common eye surgeries in the world, and the entire procedure takes less than 20 minutes. The patient does not need to stay in the hospital after the surgery and can go home. After four to six weeks, 90 percent of them no longer have blurred vision. Artificial Intelligence (AI) is being used to assist surgeons by the 100 percent Bladeless Laser Surgery – Femtosecond Laser Cataract Surgery due to recent advancements. To start off your cataract surgery journey, we will advise that you make an appointment with Dr Goh so as to allow us to do a thorough eye examination for you.
What happens in a Bladeless Laser Cataract Surgery?
The femtosecond laser uses optical pulses of optical pulses in an extremely short period of time. A femtosecond is one quadrillionth of a second. In femtosecond laser cataract surgery, issues are cut using only a cold laser. This means that no knives or sharp instruments will be used inside the eye during the procedure. Furthermore, the procedure is fully computer guided from start to finish.
First, the eye surgeon will use laser technology to map out the eyes and the unique characteristics of the eye and cataract. This includes mapping the orientation and depth of the incision, as well as the safe zone.
Following that, 3D images of the eye would be taken in order to provide real-time visualisation of the eye. To capture the entire volume of the interior segment, 10,000 individual scans will be performed. The scans will provide axial and sagittal cross-sections, allowing for precise surgical decisions.
The eye surgeon will make small incisions at the front layer of the lens after mapping and 3D scanning the eyes with the femtosecond laser. The laser will then help to break down and suction out the cataract through the small incisions.
Last but not least, a new clear intraocular lens will be implanted into the eyes, in replacement of the cataract.
Types of intraocular lens
There are different types of intra-ocular lenses available. These include:
|Multifocal lens technology|| – Both of our eyes will automatically focus on images, be it near of distanced|
– Wearing glasses would not be necessary after the surgery
|Monofocal lens technology|| – One eye will be programmed and set for near vision and another one will be set for far vision|
– The brain will naturally adopt through the neural-adaptation process
– Afterwhich, the person becomes completely unaware of the difference in lens as the brain fully transitions.
Reasons for Bladeless Laser Cataract Surgery
Cataract Surgery is primarily performed through the use of technology. The incision cuts can be pre-programmed to meet the needs of the patient using technology. Incisions can also be made at a specific length, width, and depth. As a result, the possibility of human error is eliminated. Furthermore, a clean and precise cut is required to keep the new lens in place.
More rounded and centred openings created
Since the corneal incision and circular cuts are performed by the femtosecond laser, this allows the surgeon cuts to be more precise and more centred and circular at the front of the lens capsule.
Less energy required for the procedure compared to traditional methods
The femtosecond laser uses minimal ultrasound technology to break down. This will enable the patient to reduce the risks of surgery and future complications.
Less invasive on the eyes
With technology, the need for knives and sharp instruments are no longer needed. This means that the procedure will be more gentle on the eyes. With a less invasive procedure, it could help shorten the healing process and yield better results.
Less time required compared to traditional methods
The technology and 3D imaging helps to reduce the need for complex and additional steps in the procedure. As a result, this will shorten the procedure.

Cost of bladeless laser assisted cataract surgery
The cost of Modern Laser Assisted Cataract Surgery ranges from $4000 to $7000 per eye. The maximum amount claimable by Medisave is $2450. Most insurance companies do not cover Cataract surgery, however under instances such as Traumatic Cataracts, coverage by the insurance is possible. It is crucial to find out about the different insurance coverage.
Cataract surgery recovery time is expected to be four to six weeks. Taking proper care of the eyes and following post-surgery care instructions will also aid in a quick and easy recovery. If the patient is not properly cared for, he may develop Posterior capsule opacification (PCO). This occurs when the cell in our eyes grows over the new lens, causing their vision to become cloudy once more. If this occurs, another surgery may be required.
Cataracts are a progressive condition that cannot be treated with medications; the only option is to undergo Cataract surgery. If you have blurry vision, make an appointment with an eye surgeon as soon as possible. Click on the link here to make an appointment with Dr David Goh!
