The following information is taken from my website, www.glaucomadoctor.com.au:
Removal of a cataract is one of the most common surgical procedures performed in Australia. It has a high rate of success due to the modern methods used.If the rest of the eye is healthy, the likelihood is that cataract surgery will restore good vision. If there is macular degeneration, glaucoma or diabetes, final vision may be limited by these conditions. PhacoemulsificationThe most common surgical technique is Phacoemulsification. This involves removing the natural lens and replacing it with an artificial lens. Viewing the eye through a high-powered microscope placed above the patient, Dr Yohendran will make a tiny incision at the junction where the cornea meets the sclera. A small probe is inserted to divide the cloudy lens into small pieces. The pieces are gently suctioned away. The artificial lens is inserted and held in place by the lens capsule. The artificial lens is also called an “intraocular lens implant”. It is a transparent, artificial disc with a shape similar to the natural lens. The incision is normally so small that it requires no stitches. After surgery, the eye is covered with a pad and shield for protection. The operation usually takes approximately 20 minutes. Laser Cataract SurgeryFor the last year os so, some parts of the cataract surgery have been performed with a laser (femtosecond laser). This laser is used to automate some parts of the surgery that are performed manually. Dr Yohendran can program the laser to create the corneal wound, the opening to the lens capsule, and soften the cataract. The potential advantages are due to the surgery being more predictable, and that less phacoemulsification is required to subsequently remove the lens. Whether these advantages translate into better visual outcomes is being extensively studied, with early experience being promising.
