It is sometimes necessary following cataract surgery to clear the capsule behind the intraocular lens. The normal lens of the eye is like a grape, having an outer skin and an inner-gel like material.
When a cataract forms, the material inside the lens turns cloudy and interferes with good vision. Cataract surgery removes the cloudy lens and replaces it with an intraocular implant. During the cataract surgery the fine skin (posterior capsule) of the lens is left in place to support the intraocular lens implant. In some cases, this capsule may turn cloudy and cause decreased vision or glare problems.
A Nd-YAG posterior capsulotomy is a simple procedure utilizing a special laser that creates a small opening in the posterior capsule. The technique is painless and only takes a few minutes. Most patients notice an improvement in their vision quickly and can resume normal activities immediately.
As with any surgical procedure, rare complications can occur including increased intraocular pressure, retinal detachment and dislocation of the intraocular lens.
