After cataract surgery, it is common for the membrane (or posterior capsule) behind the implant lens to become cloudy. The result may be clouding of the vision that resembles the blurring before the cataract was removed. This can be corrected with laser surgery.
The eye will be dilated prior to the surgery and anesthetic drops will be used in the eye. During the surgery, your ophthalmologist will make an opening in the center of the capsule. When the capsule is open, it allows an uninterrupted passage of light through the eye. This is a very simple, painless procedure and does not restrict the patient's routine. Your ophthalmologist may want to check the pressure in the eye about one to two weeks after the laser surgery.
Generally, the procedure works quickly and provides good results. As with any surgery, there are possible risks and complications. There is a risk that the laser may nick the implant lens, but it usually does not affect the vision. Other complications include swelling or detachment of the retina and loss of vision. Although these complications are rare, you need to beware of their existence.
