What Is a YAG Capsulotomy and How Does It Work?

Updated: Apr 17, 2023

Here we explore the concept of YAG capsulotomy, a laser treatment for secondary cataracts. The paper presents a brief overview of cataracts and explains the causes of secondary cataracts. We then elaborate on the procedure and effectiveness of yag capsulotomy for restoring vision in patients with secondary cataracts. The research indicates that YAG capsulotomy is a safe and effective procedure that has been used for over three decades to treat secondary cataracts.


Cataracts, a condition that results in the blurring of vision, is a leading cause of blindness worldwide. In the United States alone, around two million cataract surgeries are performed each year. Although cataract removal surgery is a routine procedure, post-operative complications such as secondary cataracts can lead to decreased vision. Secondary cataracts occur when the membrane surrounding the intraocular lens becomes cloudy, thereby blurring vision. In such scenarios, YAG capsulotomy is performed to restore clear vision.


Yag capsulotomy is a laser procedure that uses a neodymium-doped yttrium aluminum garnet (Nd-YAG) laser to create an opening in the cloudy membrane. The procedure takes a few minutes, and local anesthesia is all that is needed. The patient does not require hospitalisation and can leave the clinic after the procedure is complete.


Studies have shown that YAG capsulotomy is a safe and effective procedure for treating secondary cataracts. The procedure is associated with few complications, which can include temporary rise in intraocular pressure, corneal edema, and retinal detachment. Yag capsulotomy has an excellent success rate, and patients typically notice immediate improvements in their vision after the procedure. It is worth mentioning that yag capsulotomy cannot prevent or treat other causes of decreased vision such as glaucoma or macular degeneration.


YAG capsulotomy is a laser procedure that is used to treat secondary cataracts. The procedure is a safe and effective method for restoring vision in patients who have developed cloudy membranes around their intraocular lenses following cataract removal surgery. Yag capsulotomy has been successfully used for over three decades, and research indicates that it is a valuable tool for ophthalmologists and their patients. Its effectiveness, safety profile, and low complication rate make it a reliable option for those who are experiencing diminished vision due to secondary cataracts. Get your free video consultation.
