Phacoemulsification With Intraocular Lens (IOL) Implant

Cataract refers to the clouding of all or part of the focusing lens of the eye. This results in blurred or distorted vision.

The only effective way to treat cataract is to remove the clouded lens through surgery and replace it with a clear Intraocular lens (IOL) to restore your vision.
Modern surgical techniques allow your cloudy lens (cataract) to be removed quickly and painlessly through a 2.5-3mm micro-incision. The lens is broken into small fragments by high frequency ultrasound waves (phacoemulsification) delivered from a tiny ultrasound probe that is inserted into the eye. These small fragments are then aspirated out of the eye.

Once the lens is removed, it is replaced with an intraocular lens (IOL) implant which restores vision to the eye. The tiny incision is self -sealing with no stitches required.

Micro-incision, no stitch surgery has many benefits:

  • Short surgery time -15-20 minutes only.
  • Much gentler to your eye, less inflammation.
  • Less surgically-induced astigmatism with better quality vision.
  • Rapid visual recovery with a quick return to your normal activities.

The operation is a day- surgery procedure. No hospitalisation is needed.

Intraocular Lenses (IOL)

An Intraocular Lens (IOL) is a specially designed, acrylic lens that provides a permanent and safe replacement for the focusing lens in your eye, providing sharp vision at one or more distances.

After your natural cloudy lens (cataract) is removed by phacoemulsification, vision is restored by placing an IOL inside your eye. This implant is supported and held in place by the back portion of your natural lens capsule which is left intact and not removed during surgery.

The power of IOL you need is determined prior to surgery using special measurements. This IOL power can be adjusted to reduce or eliminate any pre-existing spectacle prescription (myopia, hyperopia, astigmatism and even presbyopia) so that you may no longer need any spectacles after the operation.

Once the IOL is in your eye, you will not feel or see it and no specific care is required.

Types of Intraocular Lenses (IOLS)

Monofocal IOL
This is an intraocular lens with a fixed focus for one distance, correcting for either near focus or distant focus (not both) depending on what is required. Most commonly, monofocal IOLs are chosen to correct for distance focus and you will need spectacles for reading or near-focus tasks.

Monovision Treatment is an option which involves the use of 2 monofocal lenses (1 in each eye) with different focusing distances, so that one eye is selected for reading (near) vision and the other eye selected for distance vision. This technique is generally employed for people who do not want to use reading glasses. With monovision, you do not need to make any conscious adjustments in how to see, the brain automatically adjusts so that distance and reading vision become effortless without the need for glasses.

Multifocal (Trifocal) IOL
This is a premium intraocular lens designed to provide varying focus at different distances : distance, intermediate and near focus. This multifocality has revolutionized the treatment of cataract and vision correction that can potentially eliminate your need for spectacles altogether.

Toric IOLs
Both Monofocal and Multifocal IOLs can incorporate a premium TORIC design to correct Astigmatism.
