Cataract and Cataract Surgery
Cataract is a condition in which the natural clear lens of the eye becomes cloudy and reduces the amount of light entering the eye, causing blurred vision. It is the commonest cause of blindness in the world.
Cause of Cataract
Cataract is most commonly caused by a natural aging process. It often occurs in the elderly and is believed to be related to UV light exposure. Certain medical conditions, such as diabetes mellitus, long term use of certain medication, severe injury or chronic inflammation can also increase the risk of developing cataracts. Occasionally, it may also occur in the young.
Symptoms of Cataract
- commonest symptom of cataract is a gradual, progressive blurring of vision that cannot be corrected despite wearing spectacles.
- Foggy, cloudy or hazy vision with both distant vision and near vision and things appear less bright.
- Difficulty driving at night due to bright headlights
- Trouble with glare from lamps or the sun
- Double vision
- Reduced perception of colours
- A continued change in spectacle power may signify the progression of the cataract.
The cataract can be diagnosed by seeing an eye specialist who can carry out a detailed eye examination.
Cataract Surgery Treatment
Cataract surgery is usually recommended to help restore vision if the cataract is impairing vision and affecting one’s daily activities. Cataracts may need to be removed if it is very dense and is likely to cause complications such as glaucoma.
Cataract surgery is now very advanced and can be performed safely and effectively. Lang Eye Centre makes use of the latest machines and technologies to perform cataract surgery. Dr Ang has a wealth of experience in managing normal as well as complex cataracts.
Cataract surgery is performed as a day surgery procedure and usually takes less than 30 minutes to complete. It is one of the safest and most effective day surgical procedures. The recovery is relatively fast and patients can resume most of their regular activities within a few weeks of the surgery.
The modern method of cataract removal is by phacoemulsification. A cataract surgery is a two-step process. In the first step, a small 2mm incision is made at the edge of the cornea. The cataract is softened and removed using a phacoemulsification probe. In the second step, an intraocular lens (IOL) is implanted and the wound seals on its own without the need for stitches. IOLs enable patients to see far and/or near clearly, improve astigmatism and presbyopia (Lao Hua). The patient can return home after the surgery.
Bladeless cataract surgery / Laser assisted cataract surgery
Cataract surgery can now be completely bladeless, with the use of a laser machine to help perform the various incisions in the initial part of surgery. The surgery is completed by phacoemulsification. The use of the laser can help to improve the precision and predictability of the surgery.
New and improved premium intraocular lenses provide a wider range of vision correction
We provide various high quality artificial lenses to suit each patient’s individual needs. These include aspheric monofocal lens, toric lens and multifocal lens. Aspheric monofocal lenses allow patients to see far clearly, but patients still need to use reading glasses for near work or reading. Toric lenses correct astigmatism.
Patients who wish to reduce their need for spectacles are able to do so with the use of multifocal lenses. Most multifocal lenses are traditionally focused on correcting distance and near vision (bifocal lens). Trifocal lenses are able to provide patients with distance, intermediate (computer distance) and near vision without the need for spectacles. The development of more advanced trifocal lenses which allow better light transmission has enabled patients to achieve better vision over a wider range, so that they are able to carry out most of the regular activities without spectacles. Multifocal lenses have given patients greater convenience without spectacles.
Improving outcomes with Computer-assisted cataract surgery
The accuracy of surgery may be further enhanced with computerized image guided systems. These precision imaging systems can capture high-resolution digital images of the eye prior to surgery so that surgeons can view this information as real-time computer-generated overlays during surgery. This allows for more accurate incisions and lens positioning so that the surgery is more customized and precise. This is particularly useful for patients who opt for multifocal lens implants for correction of distance and near vision, as well as patients with astigmatism. These imaging systems enable cataract surgery and lens implantation to be performed more precisely with better visual outcomes.
Why Choose Lang Eye Centre for Cataract Surgery
Experienced and Trusted Eye Surgeon in Singapore
The cataract surgery is performed by renowned Senior Ophthalmologist Dr Leonard Ang, who specialises in cataract surgery and has a proven track record in cataract treatment.
The Use of High Quality Precision Machines
At our centre, we use high quality precision machines which improve the precision and accuracy of the surgery, to help achieve a safer and more successful cataract surgery.
New and improved artificial lenses to Suit the Individual’s Visual Needs
At Lang Eye Centre, we offer patients the best artificial lenses to suit each patient’s individual needs so as to give patients the best visual outcome.
Cataract Screening to Determine the Best Treatment
Some patients with cataract are unaware of their condition, as cataracts progress very gradually and the change in their vision may not be obvious to them. Eye screening with an eye specialist can help to pick up cataract as well as other potentially blinding eye conditions earlier. We provide cataract screening to determine the best treatment available to suit our patients.
