In Singapore, cataract surgery may be performed using either conventional phacoemulsification or femtosecond laser-assisted technology. Both approaches aim to remove the cloudy lens and restore clearer vision, but they differ in how selected stages of the procedure are planned and performed.
At Angel Eye & Cataract Centre, your surgeon will assess your eyes carefully before recommending the most appropriate surgical approach for your visual needs, eye anatomy, and lens goals.
Several surgical techniques may be used for cataract surgery in Singapore, depending on how advanced the cataract has become and the overall condition of the eye.
Modern cataract surgery is most commonly performed using small-incision techniques, although older methods may still be necessary in selected cases.
Phacoemulsification, often shortened to phaco, is the standard small-incision technique used for most cataract procedures today.
During surgery, the cloudy natural lens is broken into smaller fragments using ultrasound energy before being removed from the eye. An artificial intraocular lens (IOL) is then implanted in its place.
Because the incision is small, healing is generally faster compared to older surgical methods.
Femtosecond laser-assisted cataract surgery (FLACS) incorporates laser technology into selected stages of cataract surgery planning and preparation.
Instead of performing every step manually, your surgeon may use a femtosecond laser to assist with parts of the procedure before the cataract is removed and the IOL is implanted.
FLACS may be considered when additional imaging-guided planning or greater capsulotomy consistency is relevant to the surgical plan, particularly in patients considering premium IOL options.
Extracapsular Cataract Extraction (ECCE) is less commonly performed today but may still be appropriate for particularly dense or advanced cataracts.
Instead of removing the lens through a small-incision fragmentation technique, the cataract is removed through a larger opening in the eye.
Because the incision is larger, stitches are usually required and recovery may take longer compared to modern phaco techniques.
Phacoemulsification remains the current standard of care for most routine cataract procedures due to its established clinical safety profile, minimally invasive technique, and strong long-term visual outcomes.
This type of cataract surgery is designed to remove the cloudy lens while minimising disruption to surrounding eye structures.
Before surgery, detailed measurements and scans are performed to plan the procedure, such as:
Your surgeon will also assess your:
These findings help guide lens selection and surgical planning.
During phacoemulsification, a small manual micro-incision is created at the front of the eye to access the cloudy lens.
A circular opening, known as a capsulotomy, is then created in the lens capsule. Ultrasound energy is used to break the cataract into smaller fragments before they are removed from the eye.
Once the cloudy lens has been cleared, the selected IOL is inserted into the same capsular space. The lens unfolds inside the eye and remains there permanently. Stitches are often not required for this procedure.
Phaco cataract surgery is typically performed as a day procedure in Singapore using local or topical anaesthesia.
Numbing eye drops are used so you remain awake during surgery without feeling pain, although you may still notice light, movement, or mild pressure sensations. Mild sedation may also be used in selected cases.
The procedure itself commonly takes around 15 to 30 minutes per eye, although preparation and post-operative monitoring may take longer.
Most patients return home on the same day as their phaco cataract surgery.
During the first few days, vision may appear slightly hazy while the eye heals. Mild watering, irritation, or light sensitivity can also occur temporarily.
You’ll usually be advised to:
Many patients return to light daily activities within several days, although visual stabilisation continues over the following weeks.
FLACS uses femtosecond laser technology to assist with selected stages of cataract surgery before the cataract is removed.
Rather than replacing conventional cataract surgery entirely, the laser changes how some parts of the procedure are planned and performed. Cataract removal and IOL implantation are still completed by your surgeon.
A femtosecond laser may be used to assist with:
This is performed using a computer-guided incision system that incorporates real-time imaging of the eye during surgical planning.
One of the key differences between FLACS and conventional phaco cataract surgery is that part of the cataract is softened before ultrasound removal begins. This form of automated lens fragmentation may reduce the amount of ultrasound energy needed during the next stage of surgery.
In selected cases, reducing ultrasound exposure may support greater tissue preservation, particularly within the cornea.
However, the laser does not remove the cataract entirely on its own. The fragmented lens still needs to be removed by your surgeon, and the intraocular lens must still be implanted manually.
FLACS is typically performed in two stages:
Because of this process, FLACS may involve slightly longer procedural logistics compared to standard phaco cataract surgery.
FLACS may improve the consistency and centration of the capsulotomy, which is the circular opening created in the lens capsule during cataract surgery.
The size and positioning of this opening can influence how the IOL sits within the eye afterwards.
More consistent lens positioning may become more relevant when using premium IOL designs intended for:
In selected patients, this may support more predictable refractive outcomes after eye cataract surgery.
Recovery after FLACS is often similar to conventional phaco cataract surgery.
Some studies suggest that lower ultrasound usage may contribute to less early corneal swelling in selected patients. However, recovery still depends on several factors, including:
For many patients, the overall visual rehabilitation timeline remains comparable between both approaches.
Both conventional phacoemulsification and FLACS aim to remove the cataract safely and restore clearer vision. The main differences lie in how selected surgical steps are performed and how much imaging and laser-assisted planning are incorporated into the procedure.
While FLACS introduces additional imaging-guided technology, conventional phaco surgery continues to be widely used with strong long-term clinical outcomes.

The right cataract surgery approach depends on your eyes, visual goals, and lens options.
Laser-assisted cataract surgery is typically priced differently from conventional phaco surgery. Costs may also vary depending on the surgical setting, surgeon experience, and type of IOL selected.
Standard phacoemulsification is available in both subsidised public hospitals and private clinics.
Public healthcare settings generally offer lower costs due to government subsidies, but waiting times can vary, and surgeon selection is usually limited.
Private clinics may offer:
Private clinic fees for phaco cataract surgery vary depending on:
FLACS is generally considered an elective technological upgrade and is more commonly offered in private-sector settings.
Because additional imaging systems and laser technology are involved, the procedure typically costs more than standard phaco surgery.
Additional fees may relate to:
This may result in a higher out-of-pocket top-up compared to standard cataract surgery alone.
MediSave withdrawal eligibility is generally based on the cataract surgery procedure itself rather than whether laser assistance is used.
According to current MOH guidelines:
However, elective technological upgrades and certain premium lens options may not be fully claimable under MediSave.
Your Integrated Shield Plan coverage depends on:
Coverage depends on:
Some Integrated Shield Plans may partially cover laser-assisted procedures, while others may classify certain components as non-claimable upgrades.
Pre-authorisation and detailed financial counselling are often recommended before surgery.
Before cataract surgery, your surgeon will perform a detailed ophthalmic evaluation to assess both your cataract and the overall health of your eye.
For example, if you have more complex corneal measurements or are considering premium IOLs, additional imaging-guided planning may sometimes support more predictable refractive outcomes.
Your surgeon will then recommend an individualised treatment plan based on your eye health, daily visual priorities, and expected vision goals after surgery.

Both laser-assisted and traditional cataract surgery are generally performed with minimal discomfort under local or topical anaesthesia. You may still notice mild pressure, bright lights, or temporary irritation during recovery regardless of the technique used. For most patients, overall comfort levels are broadly similar between both approaches.
Some Integrated Shield Plans may partially cover laser-assisted cataract surgery, although coverage varies between insurers and policies. Certain laser-related components may still be classified as non-claimable upgrades.
Yes, femtosecond laser technology may assist with selected aspects of astigmatism management during cataract surgery. However, the degree of correction often also depends on your corneal measurements and whether toric IOLs are used.
Bladeless cataract surgery refers to femtosecond laser-assisted cataract surgery (FLACS), where a laser assists with selected preparatory stages of the procedure. Traditional phaco surgery relies on manual surgical techniques for these same steps. In both approaches, the cataract is still removed, and the intraocular lens is implanted by a surgeon.
