What is cataract?
Treatment options for cataract surgery?
Conventional surgery (ECCE/SICS)
- Injections are given around to the eye
- Requires an incision of 7-8mm
- The cloudy eye lens(cataract) is removed in one piece
- A hard, rigid plastic lens is implanted after surgery
- Multiple stitches are required in ECCE
- Final glass prescription takes 6-8 weeks
- Post surgery precautions for 6-8 weeks
MICROINCISION CATARACT SURGERY (TOPICAL CLEAR CORNEAL PHACOEMULSIFICATION)
- Requires very small incision of 1.5 -2.8 mm
- Cataract extraction by phacoemulsification is followed by foldable lens implantation
- Walk in walk out procedure.
- No Injection required.
- Stichless, bloodless, painless surgery, Chances of infection are very low
- No need to stop intake of drugs such as aspirin and clopidogrel before surgery. Hence ideal for people with ischemic heart disease.
- Minimum post surgery precautions
- Quicker healing, so post surgery precautions for short time of 2 weeks.
TYPES OF Intraocular lenses (IOL)
Rigid IOL
Rigid IOL is made up of PMMA material, requires a 6mm incision to inject them inside the eye. Cannot be folded and inserted through phaco incision.
FOLDABLE MONOFOCAL IOL
Foldable monofocal iol are made up of acrylic and silicon material. They can inserted inside the eye through the small phaco incision.
They correct only distance vision glasses are needed for near vision.
MULTIFOCAL IOL
Multifocal foldable lens provides both distance and near vision correction in suitable candidates.
TORIC IOL
These lenses provide crisp distance vision in patients with pre-existing astigmatism. Glasses will be required for reading.
