YAG capsulotomy is a medical procedure that uses a YAG laser to treat Posterior Capsule Opacification (PCO), a common condition after cataract surgery. During cataract surgery, the cloudy lens in the eye is removed and replaced with an artificial intraocular lens. Over time, the eye’s natural cells may build up on the posterior capsule, causing blurred vision similar to looking through dirty glass.
YAG capsulotomy is a treatment for patients who have experienced decreased vision after cataract surgery due to clouding. It is a quick, non-invasive, and painless procedure that is performed in an outpatient setting and does not require hospitalization. YAG capsulotomy is generally appropriate for people who experience vision loss due to PCO and have difficulty with daily activities such as reading or driving.
Yag Capsulotomy Procedure – How Does It Work ?
The procedure is performed using a YAG laser, which is focused on the posterior capsule of the eye to create a small opening, which releases the blocked light path and allows for a return to sharp and clear vision. Before the procedure begins, the patient is given eye drops to dilate the pupil and sometimes anesthetic drops to prevent discomfort.
The doctor uses a precision laser device to make a controlled cut in the posterior capsule without damaging the intraocular lens or nearby structures in the eye. The procedure itself takes only a few minutes, after which the patient is discharged home without the need for hospitalization. Most patients experience rapid improvement in vision within hours to a few days.
When is capsulotomy necessary after cataract surgery ?
YAG capsulotomy is required when clouding of the posterior capsule of the eye occurs after cataract surgery, a condition known as Posterior Capsule Opacification (PCO). This phenomenon can develop months to years after surgery and is one of the most common reasons for a renewed decrease in visual acuity in patients who have undergone intraocular lens implantation.
The need for the procedure arises when the cloudiness affects the patient’s quality of vision to the point of impairing daily functioning. In many cases, people report decreased visual acuity, difficulty reading, severe glare especially in low light conditions or in front of strong light sources, and a feeling of fog in the eye. If these symptoms affect the quality of life and do not improve with glasses or other measures, a YAG capsulotomy may be the appropriate solution.
Symptoms indicating the need for treatment
As posterior capsule opacification worsens, the patient may feel as if their vision has returned to a state reminiscent of that before cataract surgery. One of the most prominent symptoms is the gradual onset of blurred vision, which does not improve with glasses. Many patients describe a feeling of a screen or fog in the eye, making it difficult to focus on small details.
Another symptom that may indicate the need for treatment is increased sensitivity to light, which includes severe glare, especially in bright light, such as when driving at night or in direct sunlight. In addition, there may be difficulty distinguishing colors, a general feeling of darkness in the field of vision, or even the appearance of shadows around light sources. If these symptoms become a significant nuisance and impair quality of life, it is important to consult an ophthalmologist for an examination and to assess the need for a YAG capsulotomy.
How is the process carried out ?
A YAG capsulotomy procedure is a quick, non-invasive procedure performed using a YAG laser to remove cloudiness from the posterior capsule of the eye after cataract surgery. Before the procedure begins, the patient is given eye drops to dilate the pupil and sometimes local anesthetic drops to reduce discomfort.
The treatment itself is performed in an eye clinic without the need for an operating room. The doctor uses a precise laser device that targets the capsular opacity and creates a tiny opening in it that allows light to pass unhindered to the retina. The procedure takes only a few minutes, and during it the patient does not feel any pain, except for fleeting flashes of light.
After the procedure, the patient is discharged home without the need for hospitalization. Sometimes temporary use of eye drops will be recommended to lower intraocular pressure or prevent inflammation. In most cases, improvement in vision is noticeable within a few hours to a few days, resulting in the restoration of the sharp and clear vision achieved after cataract surgery.
Advantages and disadvantages
Lag capsulotomy has significant advantages that make it one of the most common and preferred procedures for treating posterior capsular opacities. One of the main advantages is that the procedure is quick, takes just a few minutes, and is performed in the clinic without the need for anesthesia or prolonged recovery. In addition, it is a non-invasive treatment that does not require incisions in the eye, so the risk of infection is very low.
Another significant advantage is its rapid effect – most patients report significant improvement in vision shortly after treatment. The result is maintained over time, and the chance of the cloudiness returning is very low.
However, there are also disadvantages to consider. In rare cases, the procedure may cause a temporary increase in intraocular pressure, so medical monitoring is necessary, especially in patients with a history of glaucoma. Another rare risk is damage to the intraocular lens or the formation of spaces in the vitreous (floaters) that can interfere with the field of vision.
In conclusion, YAG capsulotomy is a safe and effective procedure that allows patients to enjoy sharp, clear vision again, with very few risks and side effects.
Possible side effects
YAG capsulotomy is considered a safe and effective procedure, but as with any medical treatment, side effects may occur in some patients. One of the most common symptoms is the appearance of flashes of light or “floaters” in the field of vision. These are natural changes in the vitreous of the eye that may occur after treatment but usually resolve on their own within a few days to weeks.
Another phenomenon that may occur is a temporary increase in intraocular pressure, especially in patients who suffer from glaucoma or are prone to high intraocular pressure. For this reason, in some cases the doctor will recommend the temporary use of eye drops to lower the pressure or closer monitoring after the procedure.
In very rare cases, complications such as mild intraocular inflammation, retinal edema, or changes in the position of the intraocular lens may occur. Most mild side effects resolve on their own without the need for special treatment, but in exceptional cases, medical examination should be sought to prevent further complications.
Is YAG capsulotomy dangerous ?
In general, YAG capsulotomy is considered a very safe procedure with a low complication rate. Since it is a non-invasive treatment performed using a laser, the risk of infection, bleeding, or direct damage to the eye tissue is extremely low. Most patients experience significant improvement in vision without further problems.
However, there is a small risk of side effects that require medical monitoring. In rare cases, retinal damage such as retinal detachment or macular edema may occur, especially in patients with existing risk factors. There may also be a temporary increase in intraocular pressure, which requires examination by an ophthalmologist after the procedure, especially if there is a history of glaucoma.
Despite the potential risks, YAG capsulotomy is considered the most effective solution for the treatment of capsular opacities, and is successfully performed by experienced ophthalmologists worldwide. When the procedure is performed under proper medical supervision, its benefits far outweigh the potential risks.
Recovery after YAG capsulotomy – what to expect ?
Recovery from a YAG capsulotomy is usually quick and easy, with no need for a long recovery period. Since it is a non-invasive procedure that does not involve incisions or stitches, most patients can return to their daily routine on the same day of treatment or the next day.
After the procedure, there may be temporary blurred vision, resulting from the laser flashes or from the dispersion of the capsule particles that have broken down inside the eye. This sensation usually passes within a few hours to a few days. Some patients may feel the presence of “floaters” in the field of vision, a phenomenon resulting from changes in the vitreous of the eye and sometimes lasting several weeks.
In some cases, your doctor may recommend the use of anti-inflammatory eye drops or eye drops to reduce intraocular pressure, especially if you have a history of glaucoma. It is important to seek medical attention if you experience unusual symptoms such as severe pain, a sharp decrease in vision, or the appearance of shadows in your field of vision.
YAG capsulotomy results – how long does it take to see improvement ?
Most patients experience rapid improvement in vision within hours to days after a YAG capsulotomy. Because the procedure opens a more direct path for light to pass to the retina, many report immediate sharpening of vision and significant improvement in clarity and contrast.
In some patients, improvement is gradual and lasts for several days to weeks, especially if there were minor side effects such as temporary blurring or floaters. In rare cases, if there is another medical problem with the eye, such as macular edema or severe dryness, it may take longer for full improvement.
The main advantage of YAG capsulotomy is that the result is usually permanent and does not require repeat treatment. The risk of clouding returning is very low, and most patients enjoy long-term vision improvement without the need for further intervention.
Are there any restrictions after YAG capsulotomy ?
After a YAG capsulotomy, most patients can return to their daily routine without any special restrictions. Since it is a non-invasive procedure that does not require incisions or stitches, recovery is quick and patients are not required to avoid exercise, reading, or using screens.
However, there may be temporary blurred vision immediately after the procedure, so it is recommended to avoid driving until your vision stabilizes. Additionally, if your vision is still not clear or if you experience significant flashes of light, it is best to wait until your vision has completely cleared before returning to activities that require visual accuracy, such as working at a computer or driving at night.
In some cases, doctors recommend avoiding strenuous activity such as heavy lifting or swimming for the first few days after the procedure, mainly to prevent a temporary increase in intraocular pressure. Patients with a history of glaucoma or other eye problems may need to be re-evaluated to ensure that intraocular pressure remains normal.
YAG capsulotomy versus other treatments for capsular opacity
YAG capsulotomy is currently the standard and most effective treatment for posterior capsular opacification (PCO) following cataract surgery, but there have been other approaches to treating this condition in the past. Before the development of laser technology, capsular opacification was treated with a repeat surgery, which required a delicate cut into the posterior capsule of the eye. This method was associated with a higher risk of complications, including infection and bleeding, and is therefore rarely performed today.
Another option is to wait and make optical adjustments, such as changing the number of glasses, in cases where the cloudiness is mild and does not significantly affect quality of life. However, in most cases, when there is vision impairment, YAG capsulotomy is considered the most effective solution, as it achieves quick, safe results and without the need for invasive surgery.
Due to its high success rate, the procedure has become the treatment of choice for capsular opacities and is routinely performed in eye clinics worldwide. The risk of complications is very low, making YAG capsulotomy one of the safest procedures for improving vision after cataract surgery.
How much does it cost ?
The price of a YAG capsulotomy varies depending on a number of factors, including the medical institution where the procedure is performed, the experience of the performing physician, and the patient’s eligibility for financial participation from health funds or private insurance.
In Israel, YAG capsulotomy is included in the health basket, so patients who undergo cataract surgery under the health insurance may be eligible for treatment with a low deductible or no cost at all, depending on the health insurance policy and the patient’s personal rights. However, when the procedure is performed privately, the price can range from 800 to 2,500 NIS, depending on factors such as the type of clinic, the medical equipment, and the quality of the service provided.
In cases of private health insurance, the patient may be entitled to full or partial reimbursement for the procedure, so it is recommended to check the terms of the medical policy before making an appointment.
Where can a YAG capsulotomy be performed in Israel ?
YAG capsulotomy is performed in a variety of medical settings in Israel, including public hospitals, private medical centers, and specialized eye clinics. All four health insurance companies in Israel – Clalit, Maccabi, Meuhedet, and Leumit – offer the procedure as part of basic medical insurance, according to eligibility and medical criteria determined by the treating physician.
In addition, there are private clinics specializing in ophthalmology where the procedure can be performed with shorter waiting times and under conditions tailored to the patient. These clinics operate mainly in large cities such as Tel Aviv, Jerusalem, Haifa and Beersheba, but similar services can also be found in smaller medical centers throughout the country.
Before making an appointment, it is recommended to make sure that the performing doctor is experienced in this procedure and that the clinic uses advanced laser equipment, which ensures safe and precise treatment.
