Refractive Surgery What is Refractive Surgery? Refractive surgery is also known as the term "refractive lensectomy". This means to surgically remove the eye's natural internal lens while it is still clear and transparent. Most often your natural lens should only be removed only once your vision is so blurred that you can no-longer experience clear vision. A good example would be when a cataract forms later in your life.  The Refractive Surgery procedure, is also used as a corrective therapy for people experiencing high volumes of short sighted or long sightedness. Most often the eye's natural lenses will be replaced by  lens implants. These lens implants will be specifically selected according to optical prescription to provide sharp vision for the particular eye that is having the procedure. The term "clear lensectomy" is also used to describe this type of procedure. One known con to lensectomy (Refractive Surgery) is that results can affect the eye's ability to focus close up naturally. For example, reading, knitting, typing, etc. Therefore patients that experience this would require reading glasses after lensectomy. However, the advent of new design intra-ocular lenses (IOL's) now means that many people who have refractive lensectomy are able to see up close, as well as in the long distance, without having to constantly rely on glasses as they would have had to with older design IOL's. Am I a candidate? The refractive lensectomy procedure is used if the eye has a very high prescription of long sighted or short-sightedness (i.e. more than could be treated by LASIK). Refractive lensectomy may also be appropriate in eyes that have a low prescription if the natural lens of the eye is developing a cataract that would have to be removed in the near future because it would cause a significant reduction in the quality of vision. My procedure The eye is 'numbed' for this painless surgery by using topical drops to anaesthetise the eye. An ultrasonic probe is inserted through a small incision which is only 3mm long. The ultrasonic action gently breaks up the material that makes up the eye's natural lens, and the probe suctions the fragments out of the eye. Then, the implant, or intraocular lens, is folded to fit through the 3mm incision. The implant is made from a special type of soft plastic. The implant unfolds inside the eye, and stays in position permanently. The whole surgical procedure takes around 25 minutes. Visual recovery from refractive lensectomy, in most cases, is fast and dramatic. On the day after eye surgery patients are usually able to engage in regular activities, with the benefit of increased visual freedom. Most patients experience some temporary blurring for a few days, and also some light sensitivity for a few weeks, therefore, sunglasses need to be worn more often than usual. As lensectomy is an intraocular surgery, there is a small risk that certain complications may occur, and these will be discussed with you during the consultation to help decide if this type of surgery is appropriate for you.
