Cataract repairs with Intraocular Lens replacement

Our eye works a lot like a camera. In order for us to see clearly, the light has to be focused by a lens. We are all born with a lens inside our eye that does this job for us and in early life it is crystal clear. As we age, this lens can become cloudy and begin to block light or create blur. We call this change in the lens a “cataract”.

If we live long enough, we will all develop a cataract and surgery will eventually be required. The idea of having eye surgery is usually confronting. But cataract surgery has now become one of the most commonly performed procedures worldwide with a very high degree of safety. The procedure is typically a fast, day surgery. Through a micro incision, the cataract is broken down and removed from the eye. In its place a new intraocular lens or “IOL” is inserted to do the job of focusing light. There are many types of lens designs available and not all types are suitable for all patients. Some may correct astigmatism if you have this, some may offer focus over multiple distances to reduce the need for reading glasses. The choice of the right IOL for each patient is a usually a discussion between patient and doctor.

Typically your vision will be somewhat blurry the day of the procedure, with return of clear vision over days or weeks. Complications of cataract surgery are fortunately very rare. Serious complications like infection or retinal detachment will occur in less than 1% of patients. Both are treatable if caught early and this is why keeping post operative appointments is important. Less serious complications such as swelling, a need to go back to surgery for minor adjustment or replacement of a lens, bothersome light or shadow effects can occur, but are manageable problems with existing solutions.

Satisfaction rates after cataract surgery are high. It is usually a procedure that makes a positive change to your vision and your life. If you would like more information about cataracts, please don’t hesitate to reach out to your local optician or ophthalmologist.
