When even after taking these measures the cataract doesn’t allow you to go about your daily activities, like driving or reading, the solution is having eye cataract surgery.

Eye Cataract Surgery

During an eye cataract surgery, the eye’s internal lens is replaced with an artificial lens. There is no hurry to have it done, there aren’t any additional complications associated to waiting. It’s most ideal to find a surgeon that you are comfortable with, as well as being well informed about the available possibilities, risks and benefits.

If you suffer from other eye conditions, such as galucoma, macular degeneration or diabetic retinopathy, there might be additional risks that you need to discuss with your ophthalmologist.

Types of Cataract Surgery

There are two types of cataract surgrery, phacoemulsification and extracapsular extraction.

• Phacoemulsification: It´s the least invasive kind. The natural lens is emulsified with an ultrasonic handpiece and then aspirated.
• Extracapsular cataract extraction: the center of the eye lens is extracted trhough an incision in the cornea and the remaining bits are aspirated.

In both cases, after the extraction, the natural lens is substituted with an intraocular lens implant. On a few exceptional cases, there are patients that are not a candidates for intraocular lenses, due to additional eye conditions or complications during surgery. In this case, either contact lenses or prescription glasses are used.

Cataract Surgery Risks

Cataract surgery is one of the most common and safe kinds of surgery. Over 90% of patients fully recover their vision or experience improvement. Like any other surgical procedure, it does imply a certain level of risk.
