Cataract Surgery and Intraocular Lenses (IOLs) - Different Lenses for Cataract Surgery: Which One Is Right for You?

Cataract surgery is performed using a Phaco machine, where ultrasonic waves are used to crush the solid cataract lens. A small incision of about 1.8 to 2.2 mm is made, and the needle of the phaco probe is inserted into the eye. The probe breaks the cataract into tiny pieces.

These pieces are then extracted from the eye with the help of vacuum generated by the phaco machine through the probe. Once the cataract is removed, the eye is cleared and ready for the next step.

Insertion of Intraocular Lens (IOL)

A foldable intraocular lens (IOL) is inserted into the eye at the place of the cataract.

Materials Used for IOL

Foldable lenses are made from two types of materials:

• Hydrophilic acrylic

• Hydrophobic acrylic – more advanced and inert in the eye

  
  

Types of IOL

IOLs can be Monofocal or Multifocal.

• Monofocal lens: The patient will need reading glasses but will not require glasses for distant vision.

• Multifocal lens: The patient may not need glasses for either near or distant vision.

If the patient has a cylindrical number or abnormal curvature of the cornea, a toric lens is required. This lens has specific marks and must be fitted in a particular position. Toric lenses can also be monofocal or multifocal.

Variants of Multifocal Lenses

Multifocal lenses can be:

• Actual multifocal

• Trifocal

• Extended Depth of Focus (EDOF)

However, multifocal lenses are not suitable for all patients and tend to be more expensive.
