What is cataract?

Inside the eye, there is a natural (crystalline) lens, which is transparent at birth.

When does one need to have cataract surgery?

Cataract surgery is advised when

  • 1. There is loss of vision.
  • 2. There is disturbing glare (difficulty in seeing in bright light) or haloes (seeing coloured rings around a light source).
  • 3. The cataract has become too hard, although vision is normal, which is a common situation
  • 4. Difficulty in treating other eye diseases, unless the cataract is removed.


What are the steps of cataract surgery?

Cataract surgery consists of two stages –

  • Cataract removal – Consists of removing the cataract
  • Intraocularlens (IOL) implantation– Consists of placing the IOL inside the bag.

What options do I have for cataract removal?

  • 1. Phacoemulsification – Here, the cataract is removed, with the help of ultrasound energy. Before liquefying and sucking the cataract, the steps done manually are (i) entering inside the eye, (ii) opening the anterior capsule, and (iii) breaking the cataract.
  • 2. Femto-second laser assisted cataract surgery (FLACS) – Here, a laser (femtosecond laser) is used (i) to enter inside the eye, (ii) open the anterior capsule and (iii) divide the cataract (instead of doing these steps manually). Then the ultrasound machine, same as in phacoemulsification, is used to liquefy and suck out the cataract. FLACS adds to the accuracy and precision of the procedure.

What options do I have for IOL implantation??

There are multiple options for IOL –

  • 1. Monofocal IOL – This corrects distance vision (for those without cylindrical errors). Spectacles are needed for near (i.e reading) vision after surgery.
  • 2. Toric IOL – For patients with cylindrical errors, toric IOLs are required to correct distance vision. (Else, i.e with monofocal IOLs, cylindrical spectacles will be needed for distance correction after surgery). Even with toric IOLs, spectacles will be needed for near (reading) vision.
    3. Multifocal IOL – In addition to distance vision, this provides near (reading) and/or intermediate (computer/ mobile phone) vision. The types of mutifocal IOL, depending on the distance from the eye it provides vision, are –

  • (i). Bifocal – Corrects distance and near vision.
  • (ii). Trifocal – Corrects distance, intermediate and near vision.
  • (iii). Extended depth of focus – Corrects distance and intermediate vision
  • 4. Multifocal + Toric IOL– For patients with cylindrical errors and desiringdistance, as well as near and/or intermediate vision, IOLs with both toric and multifocal properties are required.
