About Dr Leonard Ang
Dr Leonard Ang is the Senior Consultant Ophthalmologist at Lang Eye Centre. Dr Ang is a former Associate Professor at the Singapore National Eye Centre (SNEC) and the National University of Singapore. He is a fellow of the the Royal College of Surgeons (FRCS), the Royal College of Ophthalmologists (FRCOpth) and the Singapore Academy of Medicine (FAMS), and has been performing cataract surgery for over 25 years.
Cataract is the leading cause of preventable blindness worldwide. In Singapore, more than 30% of the people above 45 years of age have some degree of cataract, and by the time the reach 60 years of age, 90% of people have cataracts. The condition develops when the natural lens of the eye becomes progressively cloudy, reducing the amount of light reaching the retina and causing blurred, hazy, or dimmed vision. If left untreated, cataracts can eventually cause severe visual impairment.
The good news is that cataract surgery in Singapore is safe and effective with a high success rate. At Lang Eye Centre, our senior ophthalmologists offer the full range of cataract treatments, paired with a wide range of intraocular lens (IOL) options to suit each person’s vision goals, lifestyle and budget.
Cataract surgery in Singapore – What to expect?
Cataract surgery is performed as a day procedure and typically takes 20 to 30 minutes per eye. You are able to return home on the same day. The procedure is performed under local anaesthesia (numbing eye drops + injection near eye) or IV sedation — you usually remain awake with minimal pain and discomfort. Most people describe only a mild sensation of pressure around the eye area during the procedure.
Step-by-step: Cataract surgery procedure (phacoemulsification)
Phacoemulsification, commonly referred to as ‘phaco’, is the most commonly performed method of cataract surgery worldwide and also the most widely performed technique in Singapore. It uses ultrasound energy to break up the cloudy lens before removal, through a tiny incision that self-seals without stitches.
- Anaesthesia: Local anaesthesia (numbing eye drops + injection near eye) or IV sedation is administered. For the former, you remain fully conscious while for the latter, you will be in a dreamy state. The procedure remains comfortable with minimal pain throughout for most people.
- Small corneal incision: A self-sealing incision of 2 to 3mm is made at the edge of the cornea. No stitches are required.
- Capsulotomy: A circular opening is created in the front of the lens capsule, which is the thin membrane that holds the natural lens in place.
- Phacoemulsification: A small ultrasonic probe is inserted into the eye. High-frequency vibrations break the cloudy lens into tiny fragments, which are then gently suctioned out.
- IOL implantation: An IOL is folded and inserted through the same small incision. It unfolds and is positioned securely inside the lens capsule, where it remains permanently.
- Completion: The incision seals naturally. An eye patch is used to cover the operated eye. The procedure completes within 20 to 30 minutes.
Note: Phacoemulsification has a reported high success rate for improving vision. Serious complications are uncommon when performed by an experienced surgeon.
Intraocular lens (IOL) options
The choice of intraocular lens is one of the most important decisions in your cataract treatment, as it determines the quality and range of your vision after surgery. When the cloudy natural lens is removed, it is replaced permanently with an artificial IOL. At Lang Eye Centre, we offer the full range of IOL options, matched to your eye condition, lifestyle needs and visual goals.
Monofocal IOLs
Monofocal IOLs provide sharp vision at a single fixed distance most commonly set for far vision. If the eye is targeted for far, then the person will need reading glasses. In order to read without reading glasses, the other eye is intentionally made slightly short-sighted by about 175 to 200 degrees to help with reading. This is known as monovision – one eye for far and one eye for near.
Hence, in this case, the dominant eye is operated first to see far. If the person is satisfied with the far vision, then the other eye can be targeted to see near. But if the first eye is not sharp enough for far, then it would be better that the second eye is also targeted for far, to at least have pretty good distance vison, but then reading glasses would be required.
Hence, monofocal lens users have to be mentally prepared that they would still require glasses for reading.
Aspheric monofocal IOLs are an enhanced option that corrects spherical aberration, which causes slight blurring at the edges of vision, particularly in low-light conditions. They improve the sharpness and contrast of vision, especially at night.
Toric IOLs — For those with astigmatism
Toric IOLs are specifically engineered to correct astigmatism, which is caused by irregular curvature of the cornea resulting in distorted or blurred vision at all distances. If there is significant astigmatism, a toric IOL can substantially reduce and in many cases eliminate the need for glasses for far vision after surgery. Alignment of the toric IOL to the correct axis is critical for effectiveness.
Multifocal IOLs — Extended depth of focus lens (EDOF) and trifocal
Multifocal IOLs are designed to provide clear vision at more than one distance, reducing or eliminating the need for glasses after surgery. They achieve this by dividing incoming light into different focal zones within the lens.
1 / EDOF IOLs
EDOF IOLs extend the range of clear focus by elongating the focal point, rather than dividing light into 2 or 3 discrete zones. If people prefer sharper vision, but would like to have some range of vision, especially for intermediate vision such as computer use, then they could opt for the EDOF lens.
The vision is almost as sharp as a monofocal lens but it also provides some intermediate distance vision. But because the range is more limited, people would still be dependent on reading glasses.
If the person would like to also reduce the need for reading glasses, then just like for the monofocal lens, the dominant eye is operated first to see far and intermediate. If the vision for far is acceptable, then the other eye can be targeted to see near and intermediate by intentionally making that eye short-sighted by about 75 degrees to see near. This would mean that the far vision for the eye would not be so clear. However, if the first eye is not sharp enough for far, then the second eye should also aim for far.
Similar to the monofocal lens, there is the possibility that the person may still be fairly dependent on glasses.
2 / Trifocal IOLs
For those who prefer convenience and wish to reduce their dependence on glasses, then the trifocal lens would a good option. Because the lens enables people to see at 3 distances – far, intermediate and near. People are usually able to function without glasses for their regular daily activities.
This is a popular choice for most people as it offers the most convenience, if they are willing to accept the trade-off in visual result. For those who opt for a trifocal lens, they would do the non-dominant (reading) eye first. And if they feel comfortable with the vision, then most people would generally opt for the trifocal in the second eye as well.
On the other hand, for those who prefer the dominant eye to have sharper vision, they could opt for the monofocal or EDOF lens.
There are some conditions where the trifocal lens is not recommended. This includes those who have significant eye disease that may affect vision, such as corneal disease, glaucoma or retinal disease as these may further reduce the quality of vision. In these situations, then a monofocal lens or an EDOF lens would be the preferred choice. Trifocal IOLs are also available for those who have had previous LASIK (see below).
Regardless of lens choice, please note that if you need to read very fine print or see very far post-surgery, you can still use glasses to improve the vision, especially if there may be some residual refractive error, such as short-sightedness or astigmatism.
Summary: IOL options at a glance
| IOL type | What it provides |
| Monofocal | Far vision |
| Aspheric monofocal | Works like a monofocal lens but with reduced spherical aberration; better night vision |
| Toric | Also corrects astigmatism |
| Trifocal | Far + intermediate + near vision |
| EDOF | Far + intermediate vision |
| Monovision | One eye near, one eye far |
Computer-assisted surgery —
The VERION Image Guided System
The VERION Image Guided System is a computerised surgical planning and guidance platform that captures a high-resolution digital map of each eye before surgery. During the procedure, this map is projected as a real-time overlay onto the surgical microscope, allowing the surgeon to:
- Place corneal incisions with greater positional accuracy
- Align toric IOLs precisely to the correct axis for astigmatism correction
- Optimise the centration and rotational position of multifocal and trifocal IOLs
This system may benefit those who choose multifocal IOL options and for those with astigmatism who require toric lens placement. By reducing reliance on manual marking, the VERION system helps minimise the risk of axis misalignment, which is a key determinant of post-operative visual quality with astigmatism-correcting lenses.
Cataract surgery after laser vision correction
Those who have had previous LASIK, PRK, ReLEx SMILE, or Epi-LASIK can still have cataract surgery including the option of using multifocal IOLs. This is a common concern, and it is important to address it.
Cataract surgery treats the lens of the eye; laser vision correction (LVC) treats the cornea. These are 2 distinct structures, and prior corneal refractive surgery does not prevent cataract surgery from being performed. However, previous LVC alters the shape of the cornea in a way that can affect the accuracy of IOL power calculations, which means additional pre-operative measurements and modified calculation formulae are required.
At Lang Eye Centre, we have the diagnostic equipment and clinical experience to accurately plan cataract surgery for those who have had previous LVC. We are also able to offer multifocal lenses (EDOF and Trifocal) to this group of people.
Bladeless cataract surgery or femtosecond laser-assisted cataract surgery (FLACS)
Bladeless cataract surgery uses a femtosecond laser instead of a surgical blade to create incisions in the first phase of cataract surgery. It is also referred to as laser-assisted cataract surgery (LACS) or femtosecond laser-assisted cataract surgery (FLACS). The laser is programmed to perform 3 specific step: the corneal incision, the capsulotomy (opening in the lens capsule) and pre-fragmentation of the cataract with accuracy and reproducibility.
What steps does the laser perform?
- Creating the corneal incision at a pre-determined depth, length and angle
- Performing the capsulotomy: The circular opening in the front of the lens capsule
- Softening and pre-fragmenting the cataract, which reduces the ultrasound energy (and therefore potential energy delivered to eye tissue) needed during phacoemulsification
The cataract surgeon remains responsible for the entire procedure overseeing the laser steps, removing the lens material, implanting and positioning the IOL and managing any intraoperative findings. The laser does not replace the surgeon; it assists in selected steps.
At Lang Eye Centre, our surgeons will give you an honest, individualised assessment of whether bladeless surgery is likely to improve your outcome or whether conventional cataract surgery is equally suitable for you.
Important: The decision between conventional and bladeless surgery should be based on your individual eye condition, IOL choice, and surgeon’s recommendation. It should not be based on marketing claims about newer technology. An experienced surgeon will advise on whether laser assistance is likely to improve your specific outcome.
Cataract surgery cost in Singapore
The cost of cataract surgery in Singapore at a private eye clinic typically ranges from approximately $5,500 to $12,000 per eye, depending on a combination of factors outlined below. This is before MediSave and insurance offsets.
Factors that affect the cost
- Facility type: Day surgery centres generally charge lower facility fees than private hospitals.
- Surgeon seniority and experience: Fees reflect the surgeon’s training, sub-specialisation, and complexity of cases managed.
- Complexity of the cataract: A denser, more mature cataract, or one occurring alongside conditions such as glaucoma, a small pupil, or a history of prior eye surgery, may require more time, specialist consumables, and surgical technique adjustments.
- Choice of IOL: Standard monofocal IOLs is a more affordable option. Toric, EDOF, and trifocal IOLs carry higher costs reflecting additional engineering and clinical benefit.
- Type of cataract surgery: Femtosecond laser-assisted (bladeless) cataract surgery carries an additional cost of approximately $2,400 to $3,000 per eye in private practice compared to conventional cataract surgery.
- Anaesthesia: Either local anaesthesia (numbing drops and an injection near the eye) or IV sedation.
- Associated costs: Includes the initial consultation, pre-operative biometry and diagnostic tests, post-operative review visits and prescribed eye drops.
MediSave coverage for cataract surgery
Singapore citizens and permanent residents may claim up to $3,210 per eye from their MediSave account for eligible cataract day surgery. You may also claim from the MediSave account of an immediate family member if your own balance is insufficient.
Note: MediSave claim limits may differ depending on the complexity of the procedure, the facility, and whether the surgery meets certain criteria. The Lang Eye Centre team will provide a clear and itemised cost estimate including MediSave-eligible amounts at your consultation before any commitment is made.
Insurance coverage
Cataract surgery is claimable under most Integrated Shield Plans (IPs), corporate and overseas insurance policies if applicable. Coverage may include the surgeon’s fee, anaesthesia, operating theatre charges and IOL fee (standard monofocal) depending on your policy terms, deductible, co-payment, and whether the surgeon is on your insurance panel.
Multifocal IOL including trifocal, EDOF or toric IOLs may be classified as non-medically necessary upgrades and are not covered by insurance. These may be payable as an additional out-of-pocket amount as most insurances only covers the basic monofocal lens.
| Quick guide — MediSave & insurance: | |
| MediSave | Up to $3,210 per eye | Claimable from own or immediate family member’s account |
| Integrated Shield plans | Usually cover procedure using monofocal lens; multifocal IOL upgrades excluded |
| Corporate insurance | Pre-approval / Letter of Guarantee (LOG) from insurer required; contact your HR or insurer directly |
Cataract screening in Singapore
A cataract screening is the only reliable way to detect cataracts before they significantly impair your vision. Because cataracts develop gradually, many people adapt unconsciously to declining vision and are unaware of how much clarity they have lost. Early detection allows timely intervention before the cataract becomes dense and technically more complex to remove.
It is recommended that anyone aged 45 and above should undergo a cataract screening, even in the absence of obvious visual symptoms.
What does a cataract screening involve?
A cataract screening at Lang Eye Centre is a comprehensive eye assessment that takes approximately 2 hours including pupil dilation time. The screening includes the following components:
VISUAL ACUITY TEST
You read letters on a standardised Snellen chart at 6 metres to establish your current best-corrected vision in each eye.
REFRACTION
Your spectacle prescription including the degree of myopia, hyperopia, and astigmatism is measured using trial lenses.
Intraocular pressure (IOP) measurement
Eye pressure is measured by a tonometer to screen for glaucoma, which can coexist with cataracts and is an important pre-surgical consideration.
PUPIL DILATION
Eye drops are instilled to dilate (widen) your pupils. This allows the surgeon to examine the full extent of the lens and the retina. Your vision will be blurred and you will be sensitive to light for 4 to 6 hours after dilation.
SLIT LAMP EXAMINATION
Using a biomicroscope, the surgeon examines the cornea, iris and natural lens to identify the presence, type (nuclear, cortical, posterior subcapsular) and density of any cataract.
Results and treatment discussion
Your surgeon will explain the findings, grade the cataract and discuss whether surgery is currently indicated and if so, which surgical approach and IOL options are most appropriate for your eyes and lifestyle.
Who should schedule a cataract screening?
You should consider a cataract screening if you:
- Are 45 years old or above even with no current visual complaints
- Have noticed any of the symptoms listed earlier in this guide
- Have had multiple changes in spectacle prescription in a short period
- Have a family history of early-onset cataracts
- Have diabetes which significantly accelerates cataract formation
- Have had prolonged corticosteroid use (oral or inhaled)
- Have had significant lifetime ultraviolet (UV) light exposure
Cataract surgery recovery in Singapore —
What to expect?
Most people notice a significant improvement in vision within 24 to 48 hours of cataract surgery. Vision takes about 3 to 6 months to stablise. The overall recovery is generally smooth and well-tolerated.
The first 5 days
- Vision may appear slightly blurry or hazy immediately post-surgery as the eye heals and adjusts. This is expected and typically resolves within 24 to 72 hours.
- Use the antibiotic and anti-inflammatory eye drops exactly as prescribed. Do not miss doses.
- Wear the protective eye shield provided when sleeping to prevent accidental rubbing or pressure on the eye.
- Keep the eye dry when washing your face or hair. Avoid soap, shampoo, or water entering the eye.
- Do not apply eye makeup to the operated eye.
- Most people are able to return to office-based work within 2 to 3 days once vision has improved sufficiently
- Reading, using a computer and watching television are generally fine as soon as you are comfortable doing so.
- Driving can resume once your surgeon has confirmed your vision meets the legal standard, usually within a few days for most people.
- Can travel.
The first 2 weeks
- Do not rub the eye: This is an important instruction during the early recovery period.
The first month
- Avoid contact sports and strenuous exercise.
- Avoid swimming pools, the sea, or any water that could enter the eye.
- Attend all scheduled post-operative review appointments: Typically day 1, week 1, month 1 and 3 to 6 months post-surgery.
Full visual recovery
Full healing and visual stabilisation typically takes 3 to 6 months. Your surgeon will assess your vision at the 1-month review. If a residual refractive error remains after healing is complete, a spectacle prescription may be issued at this stage to sharpen the vision when necessary.
For those who opt for a trifocal or EDOF lens, the eyes continue to adapt for 2 to 3 months after surgery as the brain adjusts to interpreting the new lens. During this period, some people can experience seeing haloes and starburst around lights at night. Most people will learn to ignore them as time passes and carry on life as per usual.

Frequently asked questions about cataract surgery in Singapore
Is cataract surgery painful?
There is usually minimal pain and discomfort during cataract surgery. Local anaesthesia (numbing eye drops and an injection near the eye) or IV sedation is used before the procedure. Most people only experience a mild sensation of pressure or touch around the eye area for procedures using local anaesthesia. During IV sedation, most people are in a dreamy state – feeling relaxed and comfortable throughout.
How long does cataract surgery take?
The surgical procedure itself takes approximately 20 to 30 minutes per eye. You will spend additional time at the surgery centre/hospital for preparation, administration of anaesthesia, and post-operative observation. Plan to be there for a half-day. You will be discharged on the same day.
How long is the recovery for cataract surgery?
Most people notice improved vision within 24 to 48 hours of surgery. Full visual stabilisation takes 3 to 6 months. During the first 2 weeks, avoid rubbing the eye, wear the protective shield when sleeping the first week and keep the eye dry. Swimming and contact sports should be avoided for 1 month. Most can return to office work within 2 to 3 days.
Will I still need glasses after cataract surgery?
It depends on the IOL you choose. With a standard monofocal IOL, most people see far clearly without glasses but need reading glasses for near tasks. With a trifocal IOL, the majority are able to achieve functional near, intermediate, and far vision without glasses for most daily activities. Your surgeon will advise which IOL type best matches your visual goals and eye health.
Can cataracts return after surgery?
The artificial IOL does not develop cataracts and lasts for the rest of your life. However, some people may develop a condition called posterior capsular opacification (PCO). Sometimes called a ‘secondary cataract’ where the the back of the lens capsule becomes cloudy months or years after surgery. PCO is not a recurrence of the original cataract. It is easily treated in the clinic with a quick YAG laser capsulotomy procedure that takes only a few minutes.
How much can I claim from MediSave for cataract surgery in Singapore?
Singapore citizens and permanent residents may withdraw up to $3,210 per eye from their MediSave account for eligible cataract surgery. You may claim from your own account or from the account of an immediate family member. The exact claimable amount depends on MediSave board.
How much does cataract surgery cost in Singapore?
At private eye clinics and specialist centres in Singapore, cataract surgery generally costs between $5,500 and $12,000 per eye in total, depending on the surgeon’s seniority, facility, complexity of the case, IOL choice and whether femtosecond laser assistance is used. After MediSave and applicable insurance claims, out-of-pocket costs are typically lower. Lang Eye Centre provides a full and itemised cost estimate before any treatment is committed to.
What is the difference between cataract surgery and LASIK?
LASIK treats refractive errors such as myopia, hyperopia, and astigmatism by reshaping the cornea. Cataract surgery removes the cloudy natural lens and replaces it with an artificial IOL. They treat different structures for different conditions. If you have had LASIK previously, you can still undergo cataract surgery when needed though additional pre-operative measurements are required to ensure accurate IOL power calculation.
Can I have cataract surgery if I have had LASIK?
Yes, cataract surgery is possible after LASIK, PRK, ReLEx SMILE or Epi-LASIK. Previous laser vision correction does not prevent one from having cataract surgery. However, it requires modified IOL calculation methods, as the altered corneal shape affects standard biometry formulae. At Lang Eye Centre, we perform cataract surgery for post-LASIK patients and can implant trifocal IOLs in suitable cases./span>
When should I have cataract surgery?
Surgery is recommended when your cataract is affecting your ability to perform everyday activities comfortably and safely. You do not need to wait for the cataract to become ‘ripe’ or fully mature. In fact, a denser cataract is more difficult to remove and carries slightly higher surgical risk. Early intervention when vision begins to be meaningfully affected is the preferred approach. Your surgeon will advise based on your visual needs, the density and type of your cataract.
Is cataract surgery safe?
Cataract surgery is one of the most commonly performed surgical procedures in the world with a high success rate. Serious complications, such as infection (endophthalmitis), retinal detachment, or significant bleeding, occur in fewer than 1 in 1,000 cases in experienced hands. Your surgeon will discuss individual risk factors relevant to your case at consultation.
