The opacification of the normal transparent lens is called cataract. The Latin word ‘cataracta’ means ‘waterfall’. Imagine trying to peer through a sheet of falling water or through a frosted or fogged-up window. Development of Cataract varies from person to person but as a general rule, most cataracts develop slowly over a period of time. A cataract can take months or even years to reach a point where it adversely affects vision.
Most common cause of cataract is Age-related cataract
Treatment Options Available For Cataract
Phacoemulsification – A Micro Incision Cataract Surgery
Phacoemulsification is latest technology in Cataract surgery. It is a micro-incisional stitch less operation where cataract is emulsified by ultra sound energy, liquefied & sucked through the phacoemulsifier probe. A foldable intra- ocular lens is then implanted in the eye permanently.
Vision restoration is possible in a short period of time & is least traumatic with early rehabilitation & recuperation.
Advantages
- It is Stitchless. Hence healing is very fast.
- It is done under Topical anaesthesia (by putting drops.) So no need to patch the eye except in special circumstances
- Vision correction for far & near is possible
- Patient can get back to work in the shortest possible time
Intraocular Lens Implantation
During cataract surgery, the natural lens of the eye that has turned opaque is removed, resulting in loss of focusing power of the eye. This situation would be parallel to clicking a photograph without a camera lens–the picture would be extremely blurred. When the natural lens of the eye is removed an artificial implant is placed in the eye.
Intraocular Lens
An intraocular lens (IOL) implant is a synthetic, artificial lens placed inside the eye that replaces the natural lens which is surgically removed usually as a part of cataract surgery.
- Monofocal intraocular lenscan be used to give clear point focus either at a distance or close up, but one can choose only one focal point.
- Multifocal IOLsare popular as they allow correction of vision for both far & near distance.
- EDOF LensThe Extended Depth of Field (EDOF) IOL provides spectacle independence as well as correction for distant, and intermediate vision.
- Trifocal IOLsprovides excellent vision not only for near and far, but also for intermediate distances, especially for people who have routine usage of computers.
- Apodized Diffractive Multifocal IOL: Gradual diffractive steps on the IOL implant that create a smooth transition between focal points. The IOL bends incoming light to the multiple focal points to increase vision in differing light situations.
- Accomodative IOL: Crystalens and Trulign Toric currently are the only US-FDA -approved intraocular lenses (IOLs) that use a method called accommodation, enabling sharper vision at multiple distances for people who have undergone cataract surgery.
Toric IOL for astigmatism
This is a monofocal/ EDOF/ Trifocal IOL with astigmatism correction built into the lens.
- Astigmatism: This eye condition distorts or blurs the ability to see both near and distant objects. With astigmatism the cornea (the clear front window of the eye) is not round and smooth (like a basketball), but instead is curved like a football. People with significant degrees of astigmatism are usually most satisfied with toric IOLs.
Protective IOL filters
IOLs include filters to protect the eye’s retina from exposure to UV and other potentially damaging light radiation. The eye doctor selects the filters that will provide appropriate protection for the patient’s specific needs.
Other important cataract lens replacement considerations
- People who have had refractive surgery such as LASIK need to be carefully evaluated before getting IOLs because the ability to calculate the correct IOL prescription may be affected by the previous refractive surgery.
