During the initial stages of cataract, prescription eyeglasses are changed or sunglasses are worn to counter the glare from bright lights. However, these do not totally remove the cataract and are only considered as temporary measures. If not treated properly, the cataract will gradually worsen. Symptoms of Cataract varies with severity and once it starts affecting your quality of life, treatment will then be required.
With the improvement in technology, patients can now undergo surgery to effectively remove cataract. In this surgery, the cataractous lens in the eye will be removed and will then be replaced with an intraocular lens implant.
Here are some of the types of cataract surgery:
Micro-incision Phacoemulsification Surgery – this is the current standard of cataract removal. This procedure uses ultrasound energy to liquify the cataracts in the patient’s eye. It allows the emulsified cataract to be removed through a narrow incision of 2 – 3 mm. The wounds are self-healing, so stitches are not required. This allows the patient to recover and heal faster.
Laser-assisted Cataract Surgery – this procedure is known in the industry for having great potential in treating cataracts. It is considered as the next phase in the improvement of minimally invasive cataract surgery. In LACS, there is improved wound construction, gentle on the eye and allows greater predictability in lens positioning. It also offers advantages in certain forms of complex cataract surgery.
There are also different types of lens implants available in the market:
Multifocal IOLs – These lenses have different zones in different areas of the lens, enabling the patient to clearly see objects at both far and near. It decreases the need for computer or reading glasses after their cataract surgery. This is ideal for patients who find that prescription glasses are a hassle and want to be rid of them.

Toric IOLs – Astigmatism occurs when the cornea or lens are misshapen. Toric lens implants are intraocular lenses that are used to correct astigmatism using the different powers in different meridians of the lens.
Monofocal IOLs – these lenses provide corrective power in only one portion of your visual range, typically distance vision. We may select monofocal IOLs that are for near, mid, or distant focus. Only one of these three can be selected sand the focus will not change after surgery. During your exam and consultation, we can help you choose the best IOL for your needs.

Before any lens implant can be selected for you, you will need to let the surgeon know your lifestyle needs and requirements so that he is able to select a lens that is most suitable for you.
