You have had a recent eye exam and have been told that there is a membrane in your eye left over from cataract surgery that has become hazy and is impairing your vision. If left untreated, your vision will worsen over time. You have 60 days to have the laser procedure done or you will require another eye exam that is more recent.
When you arrive, a technician will check your blood pressure and you will be asked to sign a consent form. Drops will be used to dilate your pupil and to keep your intraocular pressure from going up after the laser. Once your eye is dilated, a numbing drop will be instilled into your eye; no injections or needles are used. When your eye is completely numb, a contact lens will be placed on it to help focus the laser accurately and also to keep you from blinking.
Your ophthalmologist will use a YAG laser to create an opening in the center of the cloudy capsule. The opening allows clear passage of light rays and eliminates the cloudiness that was interfering with your vision. Most patients say there is little, if any, discomfort associated with the procedure.
The actual procedure takes no more than five minutes, however you will need to have the pressure in your eye checked again after the procedure; if this is normal you will then be able to go home. Visual improvement is usually noticed once the effects from the dilating drops have diminished. You will be given a follow-up appointment to be seen within 6 weeks.


Serious complications with posterior capsulotomy are extremely rare. It is a safe and effective procedure, but like any medical procedure, it does have some risks. The most common being the rise in pressure within the eye. If this occurs then you may be given drops, or a combination of tablets and drops, to reduce the pressure. There is also a slightly higher risk of retinal detachment and also swelling of the macula both of which are rare.
Going to an eye specialist experienced with the procedure can significantly minimize the risks involved with posterior capsulotomy.
