YAG Part 1
Dr. Whitman: After cataract surgery with or without Crystalens, your vision can once again become cloudy which is often called an “after cataract”. Don’t worry – this is not another cataract; rather it is the posterior capsule of your old lens which is left to help hold the new lens implant after cataract surgery. This capsule or membrane continues to grow new cells as it ages and these cells grow over the capsule and can make the vision cloudy. For our Crystalens patients, this process can may not cloud the vision, but it can decrease good focusing movement of the lens implant.
This is completely normal and at Key-Whitman, we call it PC Haze. Typically this can begin to occur a few weeks to a few months after your Crystalens surgery.
We treat this condition by opening the capsule or membrane with a YAG laser treatment. The laser passes through the front of the eye and your lens implant without harming them at all. When the laser reaches the posterior capsule, it makes tiny openings in the membrane that are joined together to make a single larger opening that should not need treatment again in the future.
The YAG procedure is performed in our surgery center treatment room where you will sit upright in a chair for the entire treatment. Your eye will be dilated and some numbing drops are instilled. Some people have someone drive them on the day of the treatment since your eye will be dilated, but most patients feel that they can drive with sunglasses.
There are no shots, no risk of infection and again only eye drops are needed to numb your eye. You will place your head in the chin rest of the laser, just like the microscope we have in all of our exam rooms.
The treatment is quick, lasting less than a few minutes and is painless. You will focus on a green light to keep your eye still. You may see some pretty flashing lights and hear a faint clicking sound as the laser does its work. Again, you should not feel any pain.
We will check your eye pressure and go over your instructions after the procedure. Since the eye will remain numb for about 30 minutes after the procedure, please do not rub the eye – even with a tissue. It is ok to blot the corners of the eye, just don’t rub since you could cause a corneal abrasion from rubbing the eye while it is numb. It is normal to see floaters for a few days to a few weeks after treatment as the now dissolved capsule remnants may float until they dissolve away. However, if you see a large shower of floaters, flashing lights that persist, or a sudden change in vision, please contact our office right away as we will need to reevaluate your eye.
Most patients begin to see better as soon as their dilation wears off but some may notice little change. You will have an appointment to see us back in order to check on the vision after your treatment.
