Doctor, my vision did in fact clear up post my surgery, but I have noticed a return of the blur recently. That which immediately comes to mind is that the cataract has come back. But in fact cataracts do not return once they have been taken out. In most cases what we are seeing is a condition called posterior capsule opacification (PCO) which is very much treatable with a YAG laser capsulotomy. A YAG laser capsulotomy is a quick and painless laser procedure that is put in place to restore clear vision when clouding develops behind the intraocular lens which was put in during cataract surgery. Also by understanding what is causing this and how the treatment works patients can make informed decisions about their eye health.
Why Does Vision Become Cloudy After Cataract Surgery?
During cataract eye surgery the natural cloudy lens is taken out and put in a clear artificial intraocular lens (IOL). The lens is put in a thin see-through membrane which we call the posterior capsule. That capsule is left in place on purpose as it does support the implanted lens. Also we see that in some patients over time that develops into a condition we call posterior capsule opacification.
In this case what happens is that from what is left of the old lens some cells will slowly grow over the capsule which in turn causes it to become cloudy. What that does is it scatters light as it enters the eye which in turn causes blurred vision, glare, halos around lights, and reduced contrast sensitivity. Also this clouding may present itself months or even years after laser cataract surgery or traditional cataract procedures. When it does affect daily activities then the treatment which is recommended is a YAG laser capsulotomy.
What Is a YAG Laser Capsulotomy?
A YAG laser capsulotomy is a non-surgical laser treatment used to create a small opening in the cloudy posterior capsule. The procedure uses a highly precise Nd:YAG laser to remove the obstructing tissue without making any incision.
Unlike repeat cataract surgery what we do is we perform a YAG laser capsulotomy which doesn’t involve the removal or replacement of the artificial lens. What we do is restore the path which light takes to the retina thus we see improved visual clarity. Many patients report to see a difference in their vision within hours or days of the YAG laser capsulotomy.
How Common Is Posterior Capsule Opacification?
Posterior capsule opacification is a very common issue in the long term after cataract eye surgery. In fact we see that many patients within a few years of their procedure will develop some extent of cloudy capsule. That which patient’s do depends on a number of factors including age, type of surgical technique, lens used, and also how the individual heals. But on the positive side a YAG laser capsulotomy is at present the standard and very effective treatment for this issue world wide.
Symptoms That May Indicate You Need a YAG Laser Capsulotomy
Patients in need of a YAG laser capsulotomy report very much the same symptoms which they had before cataract removal. Vision may fade out gradually, reading may become a struggle, and night time driving may have you avoiding the head lights. Some report the vision is like looking through a fog or that colors no longer look bright. At first these symptoms tend to present slowly, at which point they may be easily dismissed. When vision begins to decline after prior successful cataract surgery, an ophthalmic exam can tell if a YAG laser capsulotomy will help.
Common Symptoms and Their Causes
| Symptom | Possible Cause |
| Blurred vision | Posterior capsule opacification |
| Increased glare | Light scattering from cloudy capsule |
| Halos around lights | Irregular light transmission |
| Difficulty reading | Reduced visual clarity |
| Dull color perception | Decreased contrast sensitivity |
| Reduced night vision | Capsule clouding affecting light entry |
How Is a YAG Laser Capsulotomy Performed?
Before performing a YAG laser capsulotomy ophthalmologist does a detailed eye exam to determine the diagnosis. We use eye drops which also may include those that reduce eye pressure. The patient sits at a laser machine which is the same as what is used for routine eye exams. The laser is put on the cloudy capsule behind the lens implant. We do several laser pulses which create a small opening in the center of the capsule. The whole YAG laser capsulotomy procedure usually is a few minutes. As no incision is made there are no stitches and no operating room is used. Also one of the great aspects of YAG laser capsulotomy is that it is an outpatient procedure which means patients go home the same day.
What Happens After a YAG Laser Capsulotomy?
Most patients see quick visual improvement after a YAG laser capsulotomy. In some cases better vision appears within a few hours, in others we see gradual change over a few days. Also it is not rare for temporary floaters to present right after the procedure which for the most part will go away on their own. Also at times we will give out anti-inflammatory eye drops for a short term. What we do see is that vision stabilizes rather quickly after the procedure which also is one of the most successful laser procedures in ophthalmology.
Recovery Timeline After YAG Laser Capsulotomy
| Time After Procedure | Expected Experience |
| Same day | Mild blur due to dilating drops |
| 24 hours | Noticeable vision improvement |
| 2–3 days | Reduced glare and clearer vision |
| 1 week | Vision generally stabilized |
| Follow-up visit | Eye pressure and healing assessed |
Is YAG Laser Capsulotomy Safe?
A for many years now YAG laser capsulotomy has been a common procedure that when done by a skilled ophthalmologist is very safe. As is the case with all medical procedures there are some risks but they do not present in most patients. This may include a temporary increase in eye pressure, inflammation, retinal detachment in people prone to it, or retinal swelling. Also the large scale success of YAG laser capsulotomy reports is a fact which also serious complications are rare.
YAG Laser Capsulotomy Cost in India
One out of the top issues we see from patients is related to the cost of YAG laser capsulotomy. In India what you can expect to pay for a YAG laser capsulotomy varies between hospitals, cities, which technology is used in the procedure, and also the which ophthalmologist you have. Also the cost of YAG laser capsulotomy is usually lower than that of cataract surgery as the former doesn’t require use of an operating theater or lens implant. Also which eyes require treatment will play a role in the total cost.
Patients should go over the full package which includes consultation charges and follow up visits when looking at the price of YAG laser capsulotomy. Beforehand, knowing the price of YAG laser capsulotomy helps patients to better plan out their treatment. At top eye hospitals the YAG laser capsulotomy cost typically includes the procedure, use of the laser, and post operative evaluation. Although YAG laser capsulotomy cost may vary by region the procedure is still one of the most cost effective ways to restore vision after cataract treatment. What may influence YAG laser capsulotomy cost is the hospital’s infrastructure, ophthalmologist expertise, diagnostic testing requirements and also geographical location. Also it is important for patients to note that they should not choose care based purely on YAG laser capsulotomy cost.
Can Posterior Capsule Opacification Return After Treatment?
A issue that comes up for many patients is that of if they will have to go in for another YAG laser capsulotomy down the road. The answer is mostly no. What we see is that once the opening in the capsule is made via YAG laser capsulotomy that area does not tend to cloud over again. This in turn makes the procedure a permanent solution for most.
Eye Care at ASG Eye Hospital
At our ASG Eye Hospital we see to it that every patient who reports to us with blurred vision post cataract eye surgery goes in for an in depth evaluation which is aimed at ascertaining the root cause. We may perform a YAG laser capsulotomy when we find out that there is posterior capsule opacification and thus help to return clear vision. Our ophthalmic team is into personalization of treatment plans, in depth diagnostic evaluation and which translates to better visual results over the long term. It does not matter whether a patient had conventional cataract surgery or advanced laser cataract surgery, what we are focused on is timely diagnosis and treatment for the best possible visual quality.
