Cataract
A cataract is a clouding of the eye’s natural lens, causing blurry or dim vision. It develops gradually, often due to ageing, and can make it increasingly difficult to see clearly. If left unmanaged, cataracts can lead to significant vision loss. Cataract removal surgery involves removing the clouded lens and replacing it with a clear artificial lens implant to help restore vision.
Cataracts usually develop gradually, and vision changes can be subtle at first. If you are unsure whether your symptoms require attention, a cataract specialist in Singapore can assess your eyes and advise whether treatment may be needed.
Common symptoms of cataracts include:
Some patients may also notice a temporary improvement in near vision during the early stages, sometimes referred to as “second sight”. However, this usually does not last as the cataract continues to progress.
As cataracts progress, they can begin to interfere with everyday activities. Tasks such as reading, driving, recognising faces, and watching television may become increasingly difficult.
Glare from oncoming headlights can make night driving particularly challenging. Some patients may also notice that their spectacle prescription changes more frequently as the cataract develops.
Over time, these changes can have a noticeable impact on independence and quality of life. When vision begins to affect your daily activities, you should consider cataract treatment in Singapore.
Ageing is the most common cause of cataracts. Over time, the proteins in the eye’s natural lens can begin to break down and clump together, causing the lens to become cloudy.
However, cataracts can also develop due to other factors, including:
A cataract surgeon in Singapore will take your medical history, eye health, and visual needs into account when recommending the most appropriate next steps.
Cataract surgery is one of the most commonly recommended cataract treatment options for patients whose vision has been significantly affected by lens clouding. The procedure involves removing the eye’s clouded natural lens and replacing it with a clear artificial lens, known as an intraocular lens (IOL).
A cataract operation in Singapore is typically performed under local anaesthesia and is generally well tolerated. Following surgery, patients are usually advised to rest and attend follow-up appointments so that their doctor can monitor healing and visual recovery.
At Asia Retina, a cataract clinic in Singapore, every treatment is carefully planned to not only remove the cataract but also address your vision needs through refractive correction. This includes selecting the most suitable artificial lens, also known as an intraocular lens (IOL), based on your lifestyle, visual goals, and personal preferences.
If you are looking for a cataract eye specialist, speak with Dr Claudine Pang to learn more about your cataract treatment options.
Before recommending treatment, your doctor will carry out a thorough cataract assessment to evaluate the extent of the cataract and how it is affecting your vision. This usually includes a visual acuity test, a slit-lamp examination to assess the lens, measurements of the eye’s length and curvature for lens implant planning, and a review of your overall eye health.
These findings help your doctor determine whether cataract surgery in Singapore is appropriate and which type of intraocular lens (IOL) best suits your visual needs and lifestyle.
If surgery is needed, your doctor may recommend 1 of 4 techniques.

|
Technique |
Monovision correction is a refractive strategy that involves correcting each eye with a distinct prescription, enabling one eye to focus on distant objects while the other focuses on nearby ones.
|
Multifocal IOL implantation is a cataract surgery refractive strategy that replaces the eye’s natural lens with a specially designed artificial lens providing multiple focal points for both near and distance vision.
|
Toric IOL implantation is a cataract surgery technique that corrects both cataract-related vision loss and corneal astigmatism in a single procedure by implanting a specially oriented lens.
|
Combined cataract surgery refers to a cataract procedure performed alongside another necessary eye surgery in patients with co-existing ocular conditions, allowing both issues to be treated in a single surgical session.

|
Technology Used
|
This is achieved using monofocal intraocular lenses set at different focal points for each eye, or through non-surgical and refractive methods such as contact lenses or laser vision correction.
|
Multifocal IOLs use advanced optical designs with multiple focusing zones or rings built into the lens, allowing light to be focused at different distances so that patients can see near, intermediate, and far without relying heavily on glasses. |
Toric IOLs are specially designed intraocular lenses that compensate for irregular corneal curvature. The lens is precisely aligned during surgery according to pre-measured corneal astigmatism to neutralise refractive distortion and improve distance vision clarity.
|
It involves standard cataract removal with IOL implantation, performed concurrently with additional procedures such as glaucoma surgery or retinal procedures, depending on the underlying condition. The specific techniques used vary based on the co-existing eye disease.
|

|
Suitable For
|
Patients with presbyopia or cataracts who are seeking an alternative to multifocal lenses with reduced spectacle use.
|
Cataract patients who wish to achieve a high level of spectacle independence and are suitable for adapting to the optical effects of multifocal vision, including possible visual phenomena such as halos or glare.
|
Cataract patients with corneal astigmatism who want improved unaided distance vision and reduced dependence on glasses after surgery. |
Patients who have cataracts together with other eye conditions, such as glaucoma or retinal disorders. Treating both conditions in one operation can improve overall visual outcomes and reduce the need for multiple surgeries.
|

|
Recovery Time
|
The recovery time for cataract surgery will take about 2 to 6 weeks, depending on the procedure chosen and individual factors.

Many patients also ask, “How much is cataract surgery?”. This can vary depending on the surgical method used, the type of intraocular lens selected, and the complexity of the case.
Intraocular lenses or IOL are artificial lenses that are implanted as replacement to the eye’s natural lens when it is removed in a cataract surgery. These silicone or acrylic-made lenses come in different focusing powers, just like a normal prescription glasses or contact lenses.
Multifocal IOLs are artificial lenses that are implanted as replacement to the eye’s natural lens to help clear your vision after a cataract surgery. Multifocal IOLs have more than one focusing distance. This allows vision at both distance and near.
Getting a cataract surgery done doesn’t necessarily enable freedom from eyeglasses, especially for patients who suffer from corneal astigmatism and irregular shaped corneas. Fortunately, Toric IOL, a special intraocular lenses, has been developed to allow correction of astigmatism during a cataract surgery.
Cataract surgery can be done in combination with other procedures when there are pre-existing eye conditions. In the case of concurrent glaucoma, Cataract removal may be done with a microstent or trabeculectomy to improve the eye pressure lowering effect and glaucoma control.
While early symptoms may be managed with updated prescriptions, cataracts themselves cannot be treated with medication. However, cataract surgery is a well-established and effective procedure to restore vision.
You should consider surgery when your vision starts affecting daily activities like reading, driving, or working. If glasses no longer improve your vision and daily tasks feel difficult, it’s a strong sign you may be ready.
No, the procedure is usually painless. Numbing eye drops are used, and most patients only feel mild pressure.
Most patients recover within a few days, with full healing in about 4–6 weeks.
It depends on the type of lens implanted. Some patients may still need glasses for reading or certain tasks.
